How much do builders charge per day in London?

Builders in London typically charge between £300 and £450 per day in 2026, against a UK average of around £400 per day [1]. Labourers charge less, specialist trades charge more, and London rates sit at the top of every range in the country.

That's the short answer.

The longer answer is that a day rate on its own tells you surprisingly little. What matters is how many days the job takes, what the rate includes, what quietly sits outside it, and whether a day rate is the right way to pay for your project at all.

We spend our working lives around London build costs, so this guide covers all of it: the going rates by trade, why the capital costs more, and the point at which paying by the day stops protecting you.

What does a builder's day rate actually cover?

A builder's day rate covers labour only: one person, on site, for a working day of around 8 hours. It excludes materials, skip hire, scaffolding, plant hire, VAT and the cost of any specialist trades the job needs alongside them.

This is the detail that catches people out.

A £350 day rate sounds knowable. But a bathroom strip-out that needs a skip (£250 to £350 in most London boroughs), a plumber for two days and £900 of materials has already doubled the number in your head before anyone has laid a tile.

And the eight hours deserve a closer look too. A working day includes arrival, unloading, protecting floors, setting up, clearing down and loading the van again. On a small job, that's easily 90 minutes of the day gone on logistics. It's nobody's fault. It's just why three separate one-day visits cost more than three consecutive days on site, and why good builders price them differently.

Three more things to pin down before you compare rates:

1. VAT. A VAT-registered builder adds 20% on top. A £380 day becomes £456. Always ask whether the rate you've been given is plus VAT, because most are quoted net. 
2. Team size. Some builders quote a combined rate for themselves plus a labourer (£450 to £600 is common in London). Others quote solo. Two quotes that look £150 apart may describe identical crews. 
3. Materials handling. If the builder buys materials for you, many add a 10 to 20% handling margin on top of the receipts. Reasonable for their time, but you want to know it's there before the invoice does the telling.

How much do different trades charge per day in London?

General builders in London typically charge around £300 to £450 per day, with experienced builders on demanding projects at around £50 per hour. Labourers, who handle clearing, carrying and groundwork support, typically charge £150 to £250 per day.

We tracked published rates across the major trade platforms and cost guides for 2026, and the pattern is consistent enough to plan around:

Treat these as planning figures rather than promises. Rates move with experience, postcode and how busy a trade's diary is, and inner London consistently runs 10 to 20% above outer boroughs for the same work.

A small rule of thumb worth keeping: a builder who can start tomorrow is often cheap for a reason. One booked three months out is usually booked out for a reason too.

Why are day rates higher in London than the rest of the UK?

London day rates run above the UK average because builders in the capital carry higher costs and face higher demand. The congestion charge is £15 a day, ULEZ compliance means a newer van or £12.50 a day, parking permits and fines are a running tax, storage is expensive, and travel between jobs eats billable hours. All of it lands in the rate before profit does.

Demand does the rest.

London has the country's densest concentration of period properties, and Victorian terraces generate exactly the kind of skilled, fiddly work that keeps good builders permanently busy: lath and plaster that crumbles on contact, joists that were never level, walls that have moved a little every decade since 1890.

When every street has three skips on it, nobody needs to compete on price.

When does paying a day rate make sense?

Day rates suit small, hard-to-define jobs: opening up a ceiling to find out what's leaking, repairing brickwork of unknown depth, or general maintenance where the scope genuinely can't be fixed in advance. For anything with a defined start, finish and specification, a fixed price protects you better.

The risk with day-rate work is drift.

Nobody is incentivised to finish quickly, and a two-week job that becomes a four-week job doubles your labour cost without anyone doing anything wrong on paper. You carry all of that risk. The builder carries none of it.

If you do agree a day rate, put three guardrails around it. Agree a realistic estimate of days in writing before starting. Ask for a short end-of-day update (what got done, what's next) so drift shows up in days, not weeks. And agree a trigger point, say 20% over the day estimate, where you both stop and re-scope rather than carrying on hopefully.

This is where knowing the difference between a builder's quote and an estimate earns its keep. A day rate is effectively a rolling estimate, open-ended by design. A written quote against a defined scope is a commitment, and on any project measured in weeks rather than days, a commitment is what you want.

How many days does a typical project take? 

Labour time, more than the rate itself, decides what you'll spend. A bathroom renovation typically takes 2 to 3 weeks of on-site labour, a kitchen around 3 to 4 weeks once you include first fix and finishing, and a rear extension typically runs 10 to 14 weeks with multiple trades on site.

Multiply that out and the arithmetic gets serious quickly.

Take a real-world shape of job: a 12-week house extension with an average of two people on site at London rates is £35,000 to £50,000 of labour alone, before materials, structural steel, glazing or VAT. On projects that size, day rates stop being a costing method and become a liability, which is why extensions are almost always priced as a fixed-scope contract instead.

Run the same maths on your own project before anyone starts, even roughly. Days × people × rate is a 30-second calculation, and it's the difference between a budget and a hope. For the fuller version across a whole project, our 2026 renovation cost guide and calculator breaks down typical budgets by project type and size.

How do you know the rate you're quoted is fair?

A fair day rate comes with evidence attached: insurance documents, references from recent jobs, and a clear written note of what the rate includes and excludes. A cheap rate with none of those is the most expensive thing on this page.

Comparing three like-for-like prices is the reliable test, and it works for day rates exactly as it does for quotes.

If two builders say £380 and one says £220, that third number isn't a bargain. It's a question. Sometimes the answer is innocent: a quieter diary, a lower cost base, a job that happens to be around the corner from their last one. Often it's missing insurance, missing VAT, or a plan to make the difference back once your kitchen is in pieces.

Ask the question before you sign. Our guide on how to find a good builder in London covers the checks that separate a sharp price from a shortcut.

What's the alternative to guessing with day rates?

The alternative is a defined scope, priced fixed, paid in stages.

At Beams, every project starts with a free estimate built from real project data, then a detailed scope of works, then up to three like-for-like quotes from vetted builders. The price is agreed before anyone breaks ground, payments are released in milestones as you approve completed work, and every project carries a 12-month workmanship warranty.

No day-rate drift. No arithmetic anxiety at week nine.

If you're planning a project and want a number you can actually hold on to, get your free estimate and see what it should cost before you speak to anyone.
