Pricing

London Building Prices, Service By Service

Typical London market ranges for every service we offer, drawn from the same figures published across our cost guides. These are general ranges, not fixed quotes — actual pricing always follows a free site survey.

How pricing works

General ranges, confirmed by survey

No online instant quote

Every job depends on access, existing condition and specification, so we don't offer an online instant-quote tool. The ranges below are genuine London market pricing, useful for early budgeting, but the figure that matters is the written quote you get after a survey.

A quote well below the ranges here for the same scope is usually a sign the job is priced to win cheaply and make the difference back later through extras, not a genuinely better deal. Our guide on how to tell if a builder is trying to scam you covers the checks worth doing before any money changes hands.

Questions

Pricing questions we're asked most

Are these prices fixed quotes?

No. Every figure on this page is a general London market range drawn from our published cost guides, not a fixed price for your job. Access, existing condition, specification and property type all move the final number, which is why we always survey before confirming a written quote.

Why do prices vary so much within the same range?

The lower end of a range is usually a straightforward job with good access and no hidden problems. The higher end reflects harder access, older properties where more is found once work starts, or a higher specification. A proper survey narrows that range to a single confirmed figure.

Do these prices include VAT?

Where a range isn't explicitly marked otherwise, treat it as the general market figure before VAT is itemised separately in your written quote, since VAT treatment can vary by the type of work and property. We confirm this in writing as part of every quote.

How do I get an exact price instead of a range?

Send the property address, photos if available, and a short description of the work through our contact page or by email. We survey the property, then provide a clear written scope and price before any work starts.

How do I know if a quote from another builder is reasonable?

Compare it against the ranges on this page for the same scope, and check it's broken down by labour, materials and any provisional sums rather than a single lump figure. Our guide on how to tell if a builder is trying to scam you covers the other checks worth doing before you commit.

Not sure which service you need?
