Five jobs eat up your week: pricing work, sending invoices, planning the job, replying to customers, and chasing material prices. Here's what the AI compresses each one into.
A detailed itemised quote with materials, labour and contingencies. Without AI you measure, calculate, look up prices and format. The AI builds the same quote from a plain-English description.

Every figure in the calculator is grounded in industry benchmarks and real measurements across Sleepless Tradesman's 240+ users. No vanity stats.
Sources: Federation of Master Builders surveys (2024), TradeRight admin-time studies, and our own time-tracked sample of 50 manual quotes from electricians, plumbers and builders. The 5-minute AI figure comes from production telemetry across thousands of generated quotes.
Comparing across 3+ UK suppliers (Screwfix, Toolstation, Wickes, City Electrical Factors, Plumb Center, etc.) saves 5-12% on average versus a single supplier. The 8.5% midpoint is conservative — heavy-volume tradesmen often save more.
We monetise saved hours at your rate because every hour pulled out of admin is an hour that can be billed on a job. The default rates are ONS-derived UK averages by trade. You can override yours above for a personalised figure.
Faster response times win you more enquiries; thorough plans cause fewer callbacks; branded PDFs drive referrals. These compound into real revenue but are hard to attribute to a single number — so the calculator only shows the direct, measurable savings. The total is an undercount of real-world value.
Mark is a Newcastle-based electrician with 12 years on the tools. He runs a 1-man limited company doing rewires, consumer-unit upgrades and EV charger installs. Before the AI he was losing his Sundays to paperwork. Here's a typical month with the calculator's defaults applied to his real workload.

Everything you might want to know about the calculator and the numbers behind it.
The estimates are based on industry benchmarks for how long tradesmen typically spend on quoting, invoicing, job planning, and customer messaging. We've measured each task with and without AI on real jobs across 240+ tradespeople, and the calculator multiplies the time saved by your hourly rate. Your actual savings will vary depending on job complexity and how often you re-use templates, but the figure is a realistic estimate, not a sales pitch.
Quoting takes about 2-3 hours manually for a detailed itemised quote (measuring, calculating materials, looking up prices, formatting). With Sleepless Tradesman, the AI builds the same quote from a plain-English description in about 5 minutes. Invoicing is similar — 2-3 hours of admin compressed into a single tap. Job planning runs around 3 hours per project to do thoroughly. Customer messages average 5 minutes each when you handle them manually. These are the benchmarks the calculator uses.
The AI's material price lookup searches current prices from major UK suppliers (Screwfix, Toolstation, Wickes, electrical wholesalers, plumbing merchants, timber merchants) when you build a quote. On average, comparing across at least 3 suppliers per material saves 5-12% versus sticking with one supplier. We use 8.5% as a conservative midpoint. If you already shop around manually you may save less from this; if you tend to use one supplier you may save more.
The 'money saved' figure is the value of your time saved (hours × your hourly rate) plus material cost reductions. Whether that converts to bank-account cash depends on what you do with the freed-up hours. Most tradesmen use the time for extra billable work — so saving 20 hours a month at £45/hour can mean roughly £900 in extra invoicing, on top of the direct material savings.
Sleepless Tradesman gives you 10 free AI messages to try the app — enough for a couple of full quotes — with no credit card required. Paid plans start at £29.99/month for the Starter (100 messages, photo analysis, PDF export) and £59.99/month for Premium (500 messages, real-time material pricing, unlimited threads, priority support).
No. The AI works through a chat conversation in plain English. You describe the job the way you'd describe it to a customer, and the AI handles the calculations, formatting, and PDF generation. There's nothing to configure, no spreadsheets, and no templates — if you can text a customer, you can use the app.
About 5 minutes. Sign up, upload your logo and add your business details (Gas Safe number, NICEIC registration, VAT number, etc.), and you're ready to generate your first quote. The AI learns your pricing preferences over time so quotes get more accurate the more you use it.
No — and that's a deliberate undercount. Faster, more professional quotes mean you respond to enquiries before competitors; thorough job plans mean fewer callbacks and customer disputes; branded PDF documents mean better referrals. These compound into real revenue but are hard to put a single number on, so the calculator only shows the direct, measurable time and material savings.
