How to price your labour rate as a tradesperson (2026 UK guide)

Ask most tradespeople how they arrived at their hourly rate and the answer follows one of two patterns: they looked at what the local competition charges and matched it, or they picked a number years ago and add a small amount every January. Neither approach answers the question that actually determines whether the business is financially viable: is this rate enough to cover every cost, pay you a proper salary, and generate profit?

This guide gives you the cost-build formula used by financially literate trade businesses — plumbers, electricians, gas engineers, roofers, and decorators — to calculate a minimum viable hourly rate from first principles. It covers every cost category you need to include, the right way to think about billable hours, UK regional benchmarks by trade, and how to raise your rates without losing the customers you want to keep.

The problem: revenue is not profit

The most common financial error in the trades is treating turnover as though it were take-home pay. A plumber invoicing £80,000 a year feels like they are doing well — until they subtract the van, fuel, insurance, tools, accounting, materials, tax, and National Insurance. At that point, the net position is often far closer to £30,000 than £80,000. That is less than an employed equivalent wage, with none of the employment benefits.

Undercharging is endemic across every trade, and it almost always starts with the same mistake: setting a rate without doing the maths. The tradesperson charges what feels competitive rather than what the numbers demand. The business survives, sometimes for years, because the owner works longer hours and defers purchases to paper over the gap — until something goes wrong and there is no buffer to absorb it.

The cost-build formula

The cost-build method starts from what you need rather than from what competitors charge. The formula is:

Each component requires honest inputs. Round numbers and optimistic assumptions produce a minimum rate that is still too low. The sections below walk through each one.

Step 1: your salary target

Start with what you actually want to take home — not what you currently take, not what you think is reasonable, but what your household genuinely needs plus a sensible amount for savings and pension. If you need £40,000 net per year to live comfortably, that is the number. Be honest.

Now gross it up. As a sole trader, you pay income tax and Class 4 National Insurance on your profits. In 2026, on a profit of around £55,000, you will pay roughly £7,200 in income tax (after the £12,570 personal allowance) and approximately £3,800 in Class 4 NI. That means a £40,000 net salary target requires roughly £51,000–£55,000 in pre-tax profit, depending on whether you make pension contributions (which reduce your taxable profit).

This grossed-up salary target is the number you put into the formula — not the net figure.

Step 2: your annual overhead costs

List every cost the business incurs other than materials. Materials are costed per job and marked up separately — they do not belong in your overhead calculation. Everything else does.

Van: £5,000–£8,000/year

Include depreciation or finance payments, insurance, fuel, servicing, MOT, and tyres. A tradesperson covering 20,000 miles per year in a diesel van will typically spend £3,500–£4,500 on fuel alone at 2026 prices. Add van insurance (£900–£1,800 depending on trade, age, and claims history), annual servicing (£400–£700), and either a finance payment or depreciation charge. Total van costs for most tradespeople fall between £5,000 and £8,000 per year.

Insurance: £600–£2,500/year

Public liability insurance is non-negotiable — £1m minimum cover, £2m recommended for work on occupied properties. Premiums range from around £150/year for low-risk trades (decorating, carpentry) to £600–£1,200/year for gas engineers and electricians. If you employ anyone, employer's liability insurance is a legal requirement and adds £300–£800/year. Professional indemnity is worth considering for design-and-build or specification work. Budget realistically: under-insuring to save £200/year is false economy.

Tools and equipment: £1,000–£4,000/year

Depreciate large tools over their expected life and include an annual figure for smaller purchases: drill bits, blades, PPE, testing equipment, fixings, and consumables. A plumber or gas engineer with a full complement of testing gear and power tools should budget at least £2,000/year; an electrician with a current testing kit and regular battery replacements will be similar. Do not write this off as trivial — across a career, it is one of the largest costs in the business.

Software, phone, and admin: £1,500–£3,000/year

Job management software, accounting software or accountant fees, a work mobile (or the business proportion of your personal mobile), and any subscriptions you use for the business. A realistic figure for a sole trader using a job management platform, a cloud accountant, and a dedicated work SIM is £1,500–£2,500/year. Add your accountant's annual self-assessment fee (£300–£700) and any trade certification renewal fees (Gas Safe: £420/year; NICEIC or NAPIT: varies by grade).

Marketing: actual spend, not zero

If you spend £800/year on Checkatrade, £300 on Google Ads, and £200 on a website, that is £1,300 of overhead. Include it. Tradespeople who claim to spend nothing on marketing usually mean they have stopped tracking it — they still pay for their listing, their website domain, and their time writing reviews responses.

Step 3: realistic billable hours

This is where most calculations go wrong. The temptation is to use 52 weeks × 40 hours = 2,080 hours. The reality for a UK sole trader is very different.

Subtract the following from 2,080 hours:

Using 1,500 hours is a sensible middle estimate for a sole trader in most trades. Indoor tradespeople (electricians, plumbers, gas engineers) can often achieve 1,500–1,600; outdoor trades (roofers, landscapers, groundworkers) who lose more days to weather should use 1,300–1,450.

Step 4: the full worked example

Here is a complete cost-build calculation for a self-employed plumber based in the Midlands with a salary target of £45,000 net.

The minimum rate — the rate at which the business breaks even but generates no profit — is £47.67/hour. The working rate, with a 25% profit margin added, is £60/hour. Any rate below £48/hour means this tradesperson is subsidising their customers out of their own standard of living. Any rate above £60/hour builds a buffer for slow months, bad debts, and future investment.

UK regional benchmarks by trade

Once you have your minimum rate, check it against what the local market actually sustains. If your minimum is above the regional ceiling for your trade, you need to either reduce costs or specialise in higher-value work. If your minimum is well below the regional rate, you have headroom to price higher — and you should use it.

The following benchmarks are based on 2026 data from job boards, trade forums, and Checkatrade pricing guides. All figures are for labour only, excluding materials, callout fees, or VAT where applicable.

Gas engineers typically command a 10–20% premium over standard plumbers in most regions due to the Gas Safe registration requirement and the higher liability involved. London gas engineers frequently charge £100–£140/hour for boiler diagnostics and emergency work. Specialist electricians — EV charger installers, solar PV, commercial three-phase work — can command the upper end of the London range outside the capital too, because the specialist supply is thinner.

Call-out fees and emergency rates

A standard hourly rate should not be your emergency rate. Emergency call-outs — burst pipes at 11pm, total power loss, boiler failure in January — carry real costs: you are abandoning your evening or weekend, travelling immediately rather than scheduling efficiently, and taking on higher-stress work. A 1.5× to 2× uplift on your standard hourly rate is standard practice and fully justifiable.

A fixed call-out fee covers the first visit regardless of duration: typically £60–£100 for domestic, £100–£180 for commercial. This protects you from wasted journeys where the “emergency” turns out to be a tripped breaker. After the call-out fee, the emergency hourly rate applies for time on site. Be transparent about this structure upfront — customers who are genuinely in distress will pay it; customers who object are usually not in the emergency they claimed.

Fixed price vs hourly: when each works better

Hourly rates work best for jobs where the scope is genuinely unknown at the outset: fault-finding, drainage investigations, opening up walls to assess hidden damage. Charging hourly for these jobs protects you from scope creep and rewards your expertise — a faster diagnosis should not penalise you.

Fixed pricing works better for clearly defined jobs where you can estimate accurately: a boiler service, a consumer unit replacement, a standard bathroom installation. Customers generally prefer fixed prices because they remove uncertainty. You benefit too, provided your estimate is accurate — a well-priced fixed-price job where you finish slightly early yields a higher effective hourly rate than your stated rate.

The mistake is mixing the two inappropriately: quoting fixed prices on jobs with significant unknown elements (older properties, hidden services, structural unknowns) destroys your margin when the unknowns materialise. Always include an explicit caveat in fixed-price quotes for anything that involves opening up existing structure or working on pre-2000 installations.

How to raise your rates without losing customers

If your cost-build tells you your current rate is too low, you need a plan to move to the right number. Raising rates overnight on existing customers tends to generate complaints; doing it gradually over 18 months tends to produce almost no attrition at all.

Apply new rates to new customers immediately

There is no reason to delay charging the right rate to someone who has never paid your old one. New enquiries should receive quotes at your correct rate from today. If they accept, you now have data that your market sustains the higher rate. If they do not, that information is also useful — but most will, because most price sensitivity is in the imagination of the tradesperson, not the customer.

Notify existing customers in advance

For customers you visit regularly — landlords, maintenance contracts, annual service customers — give 60 days’ notice of a rate change. A short message explaining that costs have risen significantly over the past two years and that your rate is increasing from [old] to [new] from [date] is all that is required. The vast majority of good customers will accept this without complaint.

Let attrition do some of the work

The customers you are most afraid of losing to a rate increase are usually your least profitable ones. Price-sensitive customers who push back hardest are also the ones most likely to query invoices, request discounts, and slow-pay. Raising your rates to the right level naturally filters toward customers who value quality over cheapness — which is a better business to run.

Knowing which jobs are actually profitable

Setting the right rate is necessary but not sufficient. The other half of the equation is tracking whether your jobs are actually delivering that rate in practice. It is entirely possible to charge £60/hour and still lose money on jobs that run over on time, use more materials than quoted, or require a return visit you did not price in.

Trade2Base records time on site, materials used, and invoice amounts per job, giving you an effective margin figure for every piece of work you complete. Over a few months, the data shows clearly which job types consistently deliver your target margin and which ones erode it — even when the invoice looks healthy. A plumber might discover that boiler installations at their current rate hit a 28% margin while bathroom renovations consistently land at 8% after overruns. Without that data, both jobs look fine because both generate revenue.

Your labour rate is not a set-and-forget decision. Review it annually against your actual cost base — fuel prices, insurance renewals, tool replacement cycles, and tax rates all change. The cost-build formula gives you a repeatable method: run it once a year, update the inputs, and you will always know whether your rate is still covering the ground it needs to.
