Builder day rates you should be charging
Search “builder day rates” and almost everything you find is written for the homeowner, not for you. It’s a customer working out what to pay, not a builder working out what to charge.
Those are different sums. A day rate that covers your costs and your risk looks nothing like a single number copied from a comparison site. It should still leave you a wage worth getting out of bed for. Get the maths wrong and you can be fully booked and still not making a living.
Tradesman Saver insures builders and other tradespeople, which means plenty of conversations about what cover actually needs to include and why. Pricing and protection turn out to be closer than they look. Both come down to knowing what a day of your work costs, before you’ve made a penny.
Why the “average day rate” you see online won’t tell you what to charge
Many cost-guides provide a headline day rate for builders and the numbers don’t agree with each other. One site’s national average sits well below another’s regional low. The same site will often quote a range wide enough to be almost meaningless on its own.
That’s not because one of them is right and the rest are wrong – it’s because they’re all answering a different question to the one you’re asking. Those figures tell a homeowner what to expect to pay. They say nothing about what it costs you to be available, insured, and equipped to do the job.
So is £300 a good day rate?
It might be. It might also leave you worse off than a lower number, depending on what that £300 has to cover. A day rate covering your fuel, tools, insurance, quiet weeks and tax bill is doing far more work than the same figure covering nothing but the hours on site.
There’s no universal “good” rate. There’s only a rate that covers what your business actually needs it to cover, for where you work and how you work.
What has to come out of a day rate before it’s profitable?
Before any day rate becomes your wage, it has to absorb a list of costs:
- Materials markup and waste: if you’re supplying materials, the margin has to cover price rises between quoting and buying, plus the inevitable trip back to the merchant.
- Van, fuel and tools: running costs, servicing, and replacing tools that wear out or go missing all come out of billable days, not extra ones.
- Insurance: Public liability insurance cover, and often tools and equipment cover too, protects you if something goes wrong on site. Builders insurance is an important business expense for builders, rather than simply an optional extra.
- Admin you don’t bill for: Quoting, invoicing, chasing payment and ordering materials all take real hours. None of them are billable, and all of them still have to be paid for out of the days that are.
- Tax, and the safety net employees get for free: income tax and National Insurance come off the top. So do sick pay and holiday pay. A self-employed builder doesn’t get either automatically, so they have to be built into the rate rather than assumed.
- Downtime between jobs: gaps waiting on a start date, bad weather, or a client who goes quiet don’t pause your bills. A realistic rate has to plan for days that don’t get billed at all.
How much does insurance really add?
Less than most builders assume, and it’s worth checking rather than guessing, because the answer changes what your rate needs to cover. Cover can include public liability with products liability, financial loss and legal expenses, so one policy is doing several jobs rather than one.
Treat it as a fixed cost per working day, the same way you’d treat fuel or van finance. Don’t leave it as something to think about only after a claim.
How do you actually turn your costs into a day rate?
Start from what you need to earn, not from what a website says other builders charge:
- Add up your target annual income, your business running costs (van, tools, insurance, and the rest), and your tax bill. That’s the total your day rate has to generate across a year.
- Then divide by the number of days you’ll realistically bill, not the number of working days in the calendar. Take out bank holidays, admin days, and a sensible allowance for downtime and slow weeks.
The result is a rate built from your actual costs, not from someone else’s average.
What if undercutting feels like the only way to win the work?
It’s tempting when a quote’s on the line, but it tends to cost more than it saves. Working under your real cost of doing business doesn’t just squeeze this job’s margin – it sets a rate that’s hard to raise later. It also attracts customers who chose you on price alone, and leaves nothing spare for the quiet weeks a realistic rate is meant to cover.
Underpricing costs more in the long run than it looks like it saves in the short one. Holding a rate from the start is far easier than clawing one back once customers have got used to the cheap version of you.
Does your rate need to change by region or by job?
Yes, on both counts, and that’s exactly why a single “going rate” was never going to fit your business:
Overheads in London and the South East run higher across rent, parking, congestion charges and wages. A rate that works in the Midlands or the North can leave a London-based builder short. Regional cost-guide figures reflect that gap, even where they disagree on the exact numbers.
Job type matters just as much. A straightforward day of first fix carries less risk than a structural job needing specialist skill or extra cover. The rate should reflect that difference, not treat every day as identical.
Charge what the work is worth, then make sure it’s covered
A day rate built from your own costs, not copied from a comparison site, is the one that actually pays you properly. Tradesman Saver has arranged cover for tradespeople since 1984, direct rather than through comparison sites. Public liability, products liability, financial loss, legal expenses and accidental death insurance cover are bundled in as standard, backed by Standard & Poor’s A-rated insurers.
Once your rate reflects what a working day costs, it’s worth a few minutes checking your cover reflects it too. Get a quote from Tradesman Saver today.
