AI adoption among UK trades: what the 76% figure means for your heating firm

Three quarters of trades professionals in the UK now use AI every day, according to recent Sage research. If you run a heating or plumbing firm and haven’t looked at any of this, the reason to take it seriously has nothing to do with keeping up with a trend. Your competitors are quoting faster than you, chasing invoices without the awkward phone call, and getting hours back every week.

Here’s what is actually happening, what trades use these tools for, and how to work out whether any of it is worth your time.

76% of trades use AI daily, but what does that actually mean?

Sage surveyed a broad cross-section of sole traders and small trade businesses across the UK and found 76% now use AI in some form every day to manage their businesses.

The detail is less exotic than the headline. Record keeping is the most common use at 23% of respondents, followed by payment chasing at 17%. Nearly a third of builders use AI for material cost calculations, and 43% of electricians use digital platforms to communicate directly with customers.

Very few heating and plumbing firms are running anything sophisticated. They open ChatGPT and ask it to write a quote follow-up, or use an app that sends invoice reminders for them. It adds up anyway.

The sole trader angle: who’s gaining the most

You’d expect the bigger operations to lead this, the firms with a few vans and an office manager. The data says otherwise. Sole traders are more engaged with AI than administrative staff, with 58% using it in their daily workflow.

That tracks. If you’re on the tools all day, writing quotes in the evening and chasing payments at the weekend, anything that shrinks the admin pile pays you back personally and immediately.

The stakes are worth putting in pounds. At 10 hours of admin a week and an effective rate of £45 an hour, a sole-trader plumber or electrician spends around £23,400 a year on manual processes. That’s 384 hours, or ten full working weeks, on tasks that mostly have automated solutions already.

What the broader UK picture looks like

British Chambers of Commerce research puts 54% of UK firms actively using AI in 2026, up from 35% in 2025 and 25% in 2024, a doubling in two years.

The ONS Business Insights and Conditions Survey reports a lower 23% of businesses using some form of AI in late September 2025, up from 9% in September 2023. The two surveys define AI use differently, which is why the headlines disagree.

The gap between large and small firms persists. Between 2023 and 2025, firms with 250+ employees nearly doubled their adoption to 44%, while firms under 50 employees reached 26%. The trades data suggests motivated sole traders, the ones who feel the pain of doing everything themselves, punch above their weight once they start.

The tasks where AI is actually earning its keep

Four areas save heating and plumbing firms real time rather than creating more work.

Quoting is the biggest drain for most sole traders. AI tools draft from bullet points, pull in your standard pricing and format consistently, turning a 45-minute quote into a 10-minute one.

Invoice chasing is awkward in person and easy to put off. A firm chasing five to ten overdue invoices a month loses time it could bill. Automated follow-up sequences send the reminders on schedule and take the personal sting out of it.

Tax and bookkeeping has become a pressure point as Making Tax Digital reaches more income bands. One in four survey respondents have already asked AI tools about HMRC’s updated requirements, and a fifth use the technology regularly for tax and bookkeeping support.

Customer comms, the enquiry follow-ups and job confirmations and review requests, can be templated and automated without sounding like a robot wrote them.

The time savings are real, even if the numbers vary

Studies measure this differently, so here’s the range. Federal Reserve research puts generative AI’s time saving at 5.4% of work hours on average, which is 2.2 hours in a 40-hour week, roughly a full working day back each month. At the higher end, employees at companies with ChatGPT enterprise accounts save 40 to 60 minutes a day.

For a plastering business in Leeds or an electrical firm in Bristol, the conservative end still matters. An hour a day is five hours a week, which is another job, or a Friday afternoon off.

One construction professional cut their weekly admin from three hours to twenty minutes after adopting AI tools. That takes a few months of consistent use rather than a weekend.

Why trades are actually well placed for this

Skilled trades stay largely protected from AI displacement. Nvidia CEO Jensen Huang put it bluntly: “the next millionaires will be plumbers and electricians rather than techies.”

A chatbot cannot bleed a system or diagnose a noise in a plant room. What it can do is the paperwork around the edges: the follow-ups, the scheduling, the calculations. You keep the work that earns money and hand over the admin that’s been eating your evenings.

What’s stopping people

Plenty of trades businesses are still watching from the sidelines, and the barriers are no mystery. UK Government AI Adoption Research found 60% of businesses cited limited AI skills and expertise as their main blocker, and 71% said they hadn’t identified a clear use for AI in their organisation.

For a heating or plumbing firm the “clear use” question answers itself: invoice chasing, quoting, job notes, customer follow-ups, tax queries. Five minutes with one of these tools makes the use cases obvious. The real obstacle is the assumption that it’s complicated, expensive, or built for someone who works at a desk.

Most of the tools trades use day to day are free or cost less than a tank of diesel a month.

What this means in practice for your trade business

If you already use AI daily, the question is whether it’s set up around your workflow, or whether you’re still copy-pasting between apps and doing half of it by hand.

If you haven’t started, you don’t need training or a developer. You need the one thing that costs you the most time each week, and a tool that fixes that specific thing. Get it working, then add the next one.

The trade businesses pulling ahead aren’t doing anything dramatic. They spend less time on admin than their competitors, and put that time into jobs, quotes, and occasionally finishing at a reasonable hour.

FAQ

What are UK heating and plumbing firms actually using AI for?

Record keeping (23% of respondents), payment chasing (17%), material cost calculations, particularly among builders, and customer communication, with 43% of electricians using digital platforms to talk to customers directly. Beyond the day-to-day, 27% use AI for creative inspiration and 25% for problem assessment.

Is AI going to replace heating and plumbing firms?

No. Skilled trades remain largely protected from AI displacement, because the physical, judgement-heavy work can’t be automated. AI handles the administrative layer of quoting, invoicing, scheduling and communications, which leaves more time for billable work.

How much time can AI save a sole trader?

Federal Reserve research puts average weekly savings from generative AI at around 2.2 hours in a standard 40-hour week. Targeted tools that automate invoicing and job management do better. One construction professional brought weekly admin down from three hours to twenty minutes.

Do I need to be tech-savvy to use AI tools as a heating engineer?

No. ChatGPT, AI-powered job management apps and automated invoice reminders all work in plain English. If you can send a WhatsApp message, you can use them.

Is AI adoption growing in the trades sector?

Yes, and quickly. 76% of trades professionals now use AI every day, including 73% of builders, 71% of electricians and 63% of plumbers. The gap between firms using these tools and firms that aren’t is widening.
