Health and Safety for UK Tradespeople: RAMS, CDM 2015, COSHH and On-Site Compliance Explained

Why Health and Safety Matters for Self-Employed Tradespeople

Many sole traders assume health and safety law applies mainly to large employers, not to someone working on their own or with one or two others. This is a dangerous misconception. The Health and Safety at Work etc. Act 1974 (HSWA) places duties on all employers and self-employed people. Section 3 of the Act specifically requires self-employed persons to conduct their undertakings in a way that does not expose themselves or others — including clients, members of the public and other contractors — to risks to their health and safety. Breaching this duty can result in HSE prosecution, unlimited fines in the Crown Court, and for serious offences, a prison sentence of up to two years.

Beyond criminal liability, failing to comply with health and safety law creates serious civil liability exposure. If a customer, bystander or fellow worker is injured or suffers illness because of your work, they (or their family) can bring a civil compensation claim against you. Courts will consider whether you took reasonable precautions — and a failure to carry out basic risk assessments or follow recognised safe working practices will count heavily against you. This is directly relevant to your public liability insurance: most policies contain conditions requiring you to comply with relevant legislation and regulations. A non-compliant claim can be reduced or declined by your insurer.

The HSE operates a programme of proactive site inspections as well as reactive investigations following accidents or dangerous occurrences. Construction is consistently one of the highest-risk sectors in the HSE’s annual fatal injury statistics, which is why the sector receives a disproportionate share of HSE enforcement activity. In the 2022/23 programme, the HSE prosecuted 302 cases resulting in 288 convictions, with total fines exceeding £38 million. The practical upshot for tradespeople is that an HSE visit is not a hypothetical risk — it is an event you should be prepared for, with documented risk assessments, safe working procedures, and trained workers.

Compliance with health and safety law also has a direct commercial benefit. Most principal contractors and larger commercial clients now require tradespeople to demonstrate competence and compliance before allowing them on site. Accreditation schemes such as CHAS, Constructionline and SafeContractor audit health and safety management as part of their assessment. Even smaller clients and managing agents increasingly ask to see risk assessments, method statements and public liability certificates as a matter of course. Being able to produce these documents quickly and professionally helps you win work, not just avoid prosecution.

What Is a RAMS? Risk Assessment and Method Statement Explained

RAMS stands for Risk Assessment and Method Statement. A risk assessment identifies the hazards involved in a piece of work, evaluates the likelihood that harm will occur and how serious that harm would be, and sets out the control measures you will put in place to eliminate or reduce the risk. A method statement (sometimes called a safe system of work) describes in a logical sequence how the work will actually be carried out safely, incorporating the controls identified in the risk assessment. The two documents are produced together and read as a single package — hence “RAMS”.

A RAMS is not a legal requirement for every piece of work you carry out. The legal requirement is for a risk assessment under Regulation 3 of the Management of Health and Safety at Work Regulations 1999. If you employ five or more people, the significant findings must be recorded in writing; below that threshold there is no strict obligation to write it down, though in practice you always should. A full written RAMS goes beyond the bare legal minimum — but it is standard industry practice on construction sites and is very often required contractually by principal contractors as a condition of your engagement. Refusing to produce one is functionally equivalent to not getting the job.

A well-written RAMS for a typical trade job should include: the scope and location of the work; the significant hazards identified (e.g. working at height, electrical hazards, manual handling, silica dust from cutting); the controls already in place (existing site arrangements, PPE, restricted access); the additional controls you will implement; the sequence of work; the competence and training of the people doing the work; the tools and equipment to be used; and the emergency arrangements. The level of detail should be proportionate to the complexity and risk level of the job — a one-page RAMS is perfectly adequate for many straightforward tasks, whereas complex multi-trade refurbishment work might require a far more detailed document.

The principal contractor or client should receive and review the RAMS before work starts, and their acceptance should be recorded. Workers carrying out the task should be briefed on the RAMS — this briefing should itself be documented, with signatures where possible, so you can demonstrate that the safe system of work was communicated to everyone on site. If the scope of work changes significantly during the job, the RAMS must be reviewed and updated. Keep your completed RAMS on file for at least three years — they may be needed if a health and safety incident leads to HSE investigation or a civil claim.

CDM 2015 Regulations: What Tradespeople Need to Know

The Construction (Design and Management) Regulations 2015 (CDM 2015) govern health and safety management on construction projects in Great Britain. They replaced the previous CDM 2007 Regulations and significantly extended duties to cover virtually all construction work — including small domestic projects. CDM 2015 imposes duties on clients, principal designers, principal contractors and contractors, with different obligations depending on the nature and size of the project and your role on it.

As a contractor under CDM 2015 — which includes self-employed tradespeople carrying out construction work — you have duties that apply on every project regardless of size. These include: planning, managing and monitoring the construction phase to ensure it is carried out without risk to health and safety so far as is reasonably practicable; not starting work unless a construction phase plan has been drawn up; ensuring all workers have appropriate induction and site-specific information; co-operating with any principal contractor, principal designer and other contractors on site; and reporting to the principal contractor anything that might affect the health and safety of workers or the public.

Additional notification requirements apply to notifiable projects — those that will last longer than 30 working days with more than 20 simultaneous workers, or involve more than 500 person-days of construction work. On a notifiable project the client must notify HSE (via the F10 online notification form) before work begins. A principal designer must be appointed to plan, manage and monitor the pre-construction phase, and a principal contractor must be appointed to plan, manage and monitor the construction phase and produce a construction phase plan. In practice, most small-scale trade work — single tradespeople doing domestic repairs, small extensions, or maintenance — falls well below the notifiable threshold and will not require F10 notification.

The domestic client exemption under CDM 2015 works differently from what many tradespeople assume. CDM 2015 still applies to domestic projects — it is not disapplied. What changes is who carries the client duties. A domestic client (a private individual commissioning work on their home, not used for business) does not have to fulfil the full CDM client duties themselves. Instead, those duties pass to the principal contractor by default. If no principal contractor is appointed (which is common on small domestic jobs with a single tradesperson), the duties pass to the contractor. This means that even on a domestic job, you as the sole contractor carry CDM client duties on top of your contractor duties — so you must still have a construction phase plan (which for a small domestic job can be a very simple, proportionate document) and must still manage site health and safety appropriately.

Working at Height: HSE Regulations and Hierarchy of Controls

Falls from height are the single largest cause of workplace fatalities in construction. The Work at Height Regulations 2005 (WAHR)apply to all work at height where there is a risk of a fall liable to cause personal injury. “Height” under the Regulations has no minimum — a fall from any height can cause injury, and the Regulations apply even where work is just above floor level if the risk of injury exists. The Regulations require employers and the self-employed to ensure that work at height is properly planned, appropriately supervised, and carried out in a manner that is safe so far as is reasonably practicable.

The WAHR establish a clear hierarchy of controls that you must work through in order. First, avoid work at height where possible — if the task can be done safely from ground level (using, for example, a long-handled roller instead of working from a ladder), that is the preferred option. If work at height cannot be avoided, second, prevent falls using collective protection — edge protection, guard rails, safety nets or working platforms that protect all workers rather than relying on individual action. Third, where the risk of falling cannot be eliminated, minimise the distance and consequences of a fall using equipment such as fall-arrest harnesses, airbags or crash decks. Personal protective equipment such as harnesses is always at the bottom of the hierarchy — not the first line of defence.

The question of when scaffolding is required versus when a ladder is acceptable is one of the most common practical questions from tradespeople. The Regulations do not specify a height threshold for scaffolding. The test is proportionality and risk — the duration of the task, the nature of the work, and the working conditions. Ladders and stepladders are acceptable for work that is of short duration, light effort, and where the ladder can be secured and used safely — for example, a few minutes changing a light fitting. They are not appropriate for sustained work requiring two hands, work carrying heavy materials, or work in adverse weather. For chimney repairs, roof work, external wall rendering, gutter replacement, and similar sustained tasks, you should normally use scaffolding or a properly designed mobile elevated work platform (MEWP). If you hire scaffolding, ensure the contractor is a member of NASC (National Access and Scaffolding Confederation) and that the scaffold is tagged with a handover certificate before you use it.

All work at height must be included in your risk assessment and RAMS. Equipment used for working at height — ladders, stepladders, scaffolding, MEWPs, harnesses — must be appropriate for the task, in good condition, maintained, and inspected before use. Pre-use inspection should be part of your daily routine: check ladder stiles and rungs for damage, check scaffold boards are undamaged and correctly supported, check harness webbing for cuts and buckle mechanisms for function. Keep a brief written inspection log — it takes seconds and provides evidence of due diligence.

COSHH: Controlling Hazardous Substances on Site

The Control of Substances Hazardous to Health Regulations 2002 (COSHH)require employers and self-employed persons to prevent or adequately control workers’ exposure to substances hazardous to health. A substance is hazardous to health if it appears on the Approved Supply List (substances with assigned Workplace Exposure Limits, or WELs), is classified as a carcinogen, mutagen, or reproductive toxicant, or is a biological agent, or is a dust present in high concentrations. In practice, COSHH affects almost every tradesperson on a daily basis.

For tradespeople, the most common COSHH hazards include respirable crystalline silica (RCS) — generated when cutting, drilling, grinding or sanding concrete, stone, brick and mortar; wood dust — particularly hardwood dust, which is a known carcinogen and has a strict WEL of 3 mg/m³ (softwood dust 5 mg/m³); solvents in adhesives, paints and thinners; isocyanates in two-part spray paints and coatings; and lead dust and fumes from old paintwork. Each of these requires a COSHH assessment specific to the task — identifying the substance, the route of exposure (inhalation, skin contact, ingestion), the level and duration of exposure, and the controls to be implemented (substitution, local exhaust ventilation, RPE).

Asbestos deserves particular attention. Asbestos is the single largest cause of work-related deaths in the UK, killing around 5,000 people per year. Asbestos-containing materials (ACMs) were used extensively in UK buildings until 1999, when the final types (chrysotile) were banned. Any building constructed or refurbished before 2000 may contain ACMs — in floor tiles, ceiling tiles, insulating board, textured coatings (Artex), pipe lagging, roofing sheets, and elsewhere. Before carrying out any work on a pre-2000 building that might disturb the fabric of the structure, you have a legal duty under the Control of Asbestos Regulations 2012 to check whether an asbestos register or management plan exists (the building owner or manager is required to have one for non-domestic premises), and to assess whether ACMs may be present in your work area. If you suspect you have disturbed asbestos, stop work immediately, seal off the area, and seek advice from a licensed asbestos contractor. Licensed asbestos removal work may only be carried out by a contractor holding an HSE licence.

Controlling COSHH hazards follows the same hierarchy as any health and safety risk: eliminate the substance where possible (use a water-based coating instead of a solvent-based one), substitute it for something less hazardous, reduce exposure time, enclose or ventilate the process (on-tool extraction is often the most practical approach for dry cutting), and as a last resort, provide and use appropriate respiratory protective equipment (RPE). RPE must be adequate for the task — a nuisance dust mask (FFP1 or an unrated disposable mask) is not adequate for silica dust or wood dust; HSE recommends at minimum FFP3 disposable or P3 reusable half-mask respirators for these hazards. Health surveillance — for example, lung function testing for workers regularly exposed to asthmagens — may also be required under COSHH for certain activities.

Electrical Safety: Part P Building Regulations and Competent Person Schemes

Part P of the Building Regulations (England)governs the safety of electrical installations in dwellings. It requires that all electrical installation work in domestic premises that is “notifiable” — broadly, work on a new circuit, replacing a consumer unit, or adding a circuit in a bathroom or kitchen — must either be carried out by a person registered with an approved competent person scheme (CPS) who self-certifies the work, or must be notified to the local authority Building Control department before work begins, inspected, and a completion certificate issued. The scheme was introduced in 2005 following a significant number of electrical fires and fatalities attributable to unsafe DIY and unqualified electrical work in homes.

The main approved competent person schemes for electricians are NICEIC, NAPIT, ELECSA and STROMA. As a registered member, you can self-certify notifiable electrical work in dwellings — which means you issue a Building Regulations Compliance Certificate to the client, notify the local authority through the scheme’s online portal, and record the work in the scheme’s database. This is far more efficient for clients than the Building Control notification route, which typically involves a fee, a formal inspection, and administrative delays. For a full breakdown of electrician registration pathways, see our electrician certification guide.

Non-notifiable electrical work — for example, like-for-like replacement of accessories (sockets, switches, light fittings) on an existing circuit, or adding a spur from an existing ring in a non-special location — does not require notification or CPS registration. However, all electrical work, whether notifiable or not, must comply with BS 7671 (the IET Wiring Regulations), which sets the technical standards for electrical installation design, selection and erection, and verification. Failing to comply with BS 7671 is not a criminal offence in itself (unless it breaches Building Regulations) but creates serious civil liability if the non-compliant installation causes a fire or electrocution.

It is also important to understand that Part P is an England-specific regulation. Wales has its own Building Regulations (Part P applies similarly); Scotland has its own Building Standards (Technical Handbook — Domestic, Section 4.5 covers electrical safety); and Northern Ireland has its own Building Regulations. If you work across borders, check the applicable regime. In all cases, however, the practical message is the same: notifiable electrical work on domestic premises requires either CPS membership and self-certification or Building Control notification — doing it without either route, even if technically competent, leaves both you and your client in breach of Building Regulations.

Personal Protective Equipment (PPE): Employer and Self-Employed Obligations

The Personal Protective Equipment at Work Regulations 1992 (as amended 2022) require employers to provide suitable PPE to employees where risks cannot be adequately controlled by other means. Importantly, the 2022 amendment extended these regulations to limb (b) workers — broadly, self-employed individuals who are economically dependent on a single engager, which covers many subcontractors and gig-economy workers in the trades. If you supply workers to a principal contractor, you should check whether they are classified as limb (b) workers under the amendment, as this changes your PPE obligations.

Even aside from the 2022 amendment, the self-employed have always had duties under COSHH and the Working at Height Regulations to use appropriate PPE where required by the risk assessment — PPE is the last line of defence in the hierarchy of controls, but it is a mandatory line of defence where other controls are insufficient. PPE provided must be appropriate for the risk, fit correctly, be compatible with other PPE worn simultaneously (for example, a hard hat must not prevent a face shield from fitting properly), and be maintained in good repair and replaced when worn or damaged.

The minimum PPE for most site-based trade work includes: safety boots or shoes (ISO 20345 S1P or S3 standard for most general site use, with midsole puncture protection for work near nails or rebar); hard hat/safety helmet where there is overhead risk (EN 397 standard); high-visibility vest or jacket (EN ISO 20471 class 2 or above on most contractor sites); safety glasses or goggles when cutting, grinding, or working overhead; gloves appropriate to the task (cut-resistant for steel fixing; chemical-resistant for solvents; general-purpose leather for handling materials). Hearing protection should be provided where noise levels exceed 80 dB(A) (the first action level under the Control of Noise at Work Regulations 2005); above 85 dB(A) hearing protection must be used.

PPE must be CE or UKCA marked (post-Brexit, UKCA marking is required for PPE newly placed on the GB market, though CE-marked stock placed before October 2023 remains valid). Be cautious of cheap, unbranded PPE sold online — counterfeit safety products are a genuine market problem, and non-compliant PPE that fails to protect you in an incident may also affect a negligence claim. Keep purchase records for PPE and inspect items before each use. Disposable items like dust masks have finite service lives — an FFP3 mask used for a full day in heavy dust should be replaced.

Tool and Equipment Safety: PAT Testing and Inspection Records

Portable appliance testing (PAT) is the process of inspecting and testing portable electrical equipment to ensure it is electrically safe. Despite what many people believe, PAT testing is not required by law for every portable appliance in every situation. The legal requirement — under the Electricity at Work Regulations 1989 and the Provision and Use of Work Equipment Regulations 1998 (PUWER) — is that electrical equipment be maintained in a condition that is safe. PAT testing is one way of demonstrating that maintenance, but it is not the only way, and there is no legal requirement for annual testing of all equipment.

In practice, however, PAT testing is expected by most commercial clients and principal contractors as a condition of bringing portable electrical equipment on site. Many site rules require all electrical tools and equipment to display a current PAT test label showing the test date, the next test due date, and the tester’s details. If you regularly work on commercial sites — offices, factories, hospitals, schools — you should have your portable tools PAT tested by a competent person at intervals appropriate to their use and the environment. For tools used frequently on construction sites (high-risk environment), annual testing is typical. Keep a register of your equipment with test dates, results and next test dates — this doubles as an inventory for insurance purposes.

Beyond PAT testing, PUWER requires that all work equipment — including hand tools, power tools, lifting equipment, scaffold, ladders and MEWPs — is suitable for the intended use, properly maintained, and inspected at appropriate intervals. For most hand tools this means a visual check before use and routine maintenance such as blade sharpening, lubrication and checking guards. For lifting equipment (hoists, straps, shackles, scaffold lifts) the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) require thorough examination by a competent person at intervals not exceeding six months for lifting equipment used to lift people, or twelve months for other lifting equipment. Maintain inspection records for all LOLER-regulated equipment.

Equipment faults identified during inspection must be taken out of service immediately and clearly tagged as defective so no one uses them. On a busy site it is not sufficient to leave a broken tool in the van or in a corner — label it clearly “Do Not Use — Awaiting Repair” and keep it separate from serviceable equipment. Continuing to use equipment that is known to be faulty is a straightforward breach of PUWER and would be treated seriously by an HSE inspector or, in the event of an accident, by a civil court.

Public Liability Insurance and Health & Safety Non-Compliance

Health and safety compliance and public liability insurance are deeply linked. Your PL policy is a contract, and that contract contains conditions. Almost all trade insurance policies include conditions requiring you to comply with relevant legislation and regulations — which includes health and safety law. If you suffer a loss or a claim is made against you and the insurer discovers that you were in breach of a legal duty (for example, you were carrying out work at height without any fall protection, or you disturbed asbestos without appropriate controls), the insurer may argue that the breach was the proximate cause of the loss and seek to reduce or decline the claim.

This is not a theoretical risk. In practice, insurers investigate the circumstances of serious injury claims carefully. If a claimant was injured because you were working in a way that breached the Working at Height Regulations or COSHH, your insurer’s lawyers will identify this quickly, and it will be used both to contest liability (arguing the injured party contributed to their own loss) and potentially to question coverage. Non-compliance that voided or reduced your insurance cover would leave you personally responsible for the compensation award, legal costs and any HSE penalties — a combination that could be financially catastrophic for a sole trader.

There is also a reputational and commercial dimension. If a serious accident occurs on one of your jobs and results in HSE investigation or prosecution, this becomes a matter of public record. News of a prosecution can spread quickly in a local trade community. Principal contractors who previously gave you work may cease to do so if your H&S record becomes a risk to their own CDM compliance. Accreditation schemes like CHAS and SafeContractor audit your claims history and enforcement record — a prosecution could result in loss of accreditation. You can use our tradesman insurance calculator to estimate the cost of cover appropriate to your trade and turnover.

The practical message is that health and safety compliance and adequate insurance are not alternatives — they are complements. Good compliance reduces the likelihood of an accident; adequate insurance protects you if one happens despite your precautions. Neither on its own is sufficient. A well-run trades business treats H&S compliance as a routine part of job preparation — not as a box-ticking exercise for inspectors, but as the framework that protects you, your workers, your clients, and your livelihood.
