Trades lose around 8 hours a week to admin, mostly evenings

If you are a plumber, electrician, builder, or gas engineer running a small UK business, you are losing around 8 hours a week to admin. That is the median figure from HoursBack assessment data across UK trades.

8 hours sounds like less than the other sectors. It is. But you do most of it in the evening, after a 10-hour day on the tools. And every hour you spend quoting, invoicing, or chasing is an hour you are not earning.

At £37.50 an hour across the 46-week UK working year, that is £13,800 a year per person. Not a small number when your margins are tight and your weekends are short.

Here are the five biggest time sinks for UK trades, the AI tools that solve them, and three quick wins you can try this week.

The numbers behind the headline

The maths: weekly admin hours × hourly rate × 46 weeks.

• 8 hours × £37.50 × 46 = £13,800 per person per year (mid-range trade rate)
• 8 hours × £25 × 46 = £9,200 (labourer or junior rate)
• 8 hours × £50 × 46 = £18,400 (specialist, gas-safe, or higher-skilled trade)

Your number will depend on what you charge per hour and how many people you have. Run it in the calculator with your own rate. The 8-hour weekly admin figure is the median from HoursBack assessment data (n=20+).

Quotes, invoices, and chasing are the big three. Fewer hours than the office-based sectors, but the pounds-per-hour impact is higher because that time comes out of your earning hours, not from a salaried desk.

Top 5 time sinks for UK trades businesses

1. Quote writing. Customer wants a price for a bathroom refit, a rewire, a boiler swap. You measure up, then sit at the kitchen table on a Tuesday evening typing out the quote, pricing in materials, listing assumptions. 45 to 90 minutes a quote. Run five quotes a week, that is half a working day.

2. Invoicing. Job done, customer happy. Now you have to write the invoice with the right description, the right VAT line if you are registered, the right reference. Then you have to send it, and chase it 14 days later. 15 to 25 minutes per invoice if you do it carefully.

3. Chasing late payments. The job where they said "settle up at the end" and now it has been three weeks. Writing the polite chase. Writing the firmer chase. Phoning. Most trades hate this and put it off, which costs cash flow.

4. Materials ordering and supplier emails. Phoning the wholesaler, sending the parts list to the merchant, sorting next-day delivery to the right address. 20 minutes a job that you do not bill for.

5. Customer follow-up and review chasing. The "everything OK?" message a week after the job, the gentle ask for a Google review, the keeping-in-touch text six months later. Most trades never do this because they do not have a system - and they lose repeat work as a result.

3 AI tools that solve them

TraidHand (specifically built for UK trades) - the AI agent designed for quote drafting, customer follow-up, and the messy bits of running a trades business. Built around how a plumber or electrician actually works, not how an office worker imagines they work. The strongest fit for any UK trade running solo or with a small team. (Full disclosure: David from HoursBack is a co-founder, which is also why we know it works.)

ChatGPT (Plus, around £20 a month) - for drafting quotes from a few bullet points, writing polite chase messages, and replying to enquiries when you have not got time to think. You feed it: "Quote for a customer in Bromley for a bathroom refit, three weeks of work, you supply materials, here is the rough list, total £8,400." It gives you a tidy quote draft you edit and send. Suits any trade who can use a phone.

Xero or QuickBooks (around £14-£42 a month) - invoicing, automated late-payment reminders, and Making Tax Digital if you are VAT-registered. Both let you send an invoice from your phone in under 60 seconds and chase it automatically. If you are still using Word documents and paper invoices, this is the single highest-impact change you can make. Suits any trade earning over £30,000 a year.

Quick wins to try this week

1. Set up three ChatGPT prompts on your phone for your most common admin texts. "Polite chase for an overdue invoice on a £[amount] job from [date]." "Quote acknowledgement to a new customer with timeline." "Thank-you and review ask after a completed job." Pre-fill the context once, save the prompt, paste in the variables when you need it. 4 minutes saved per message. Over a week, 60-90 minutes back.

2. Move all invoicing to a phone-based app (Xero or QuickBooks). Stop typing invoices on the laptop in the evening. Send them from the customer's driveway as soon as the job is done. You will get paid faster and you will get your evenings back.

3. Set up a 7-day automatic chase on every invoice. Both Xero and QuickBooks do this in two clicks. The chase email goes out without you doing anything. Most late payments get paid as soon as the first automatic reminder arrives, because they were just forgotten. Saves you the awkward phone call.

What an Assessment unlocks

The calculator and these tips will get you started. They will not tell you which CRM is worth the money for a 3-van team, how to route enquiries to the right engineer without sitting in the office all day, or how to roll out a quoting system that does not annoy your existing customers.

An AI workflow assessment does. We run a 60-minute call, produce a custom 48-hour report with named tools, exact steps, and a 7-day plan, and back it with a money-back guarantee if we do not surface 5+ hours a week. £799 - one big quote's worth, and we work it out from your actual day, not a template.
