What affects the price of a building job in London
No two jobs cost the same, which is why we do not publish a single average. These are the things builders usually take into account:
- The scale of the work, from a small repair to an extension or a structural change.
- The design: drawings, structural advice and any approvals needed before the work starts.
- Materials and finishes, which you often choose and which can change the price a lot.
- Groundwork, access for materials and where waste can be taken away.
- How the job is split between trades, and whether the builder manages them or you do.
London homes range from Victorian houses to purpose-built flats and new conversions. Period and listed homes may need consent before changes, so ask the builder what to check with the council. In flats, check the lease and speak to the managing agent about access and permissions before building work.

Frequently asked questions
How do I get an accurate quote for a building job in London?
Describe the finished result, share any drawings or sketches and say whether you have approvals in place. Photos of the space and the garden or access route help. The more a builder can see before quoting, the less likely the price is to change later.
Do builders in London charge for a call-out or a visit?
It depends on the builder and the job. Some charge for a visit, some do not, and some include it in the quote. Ask before anyone comes out and check that the written quote says what is and is not included.
What should I check before hiring a builder in London?
Ask about a written quote that sets out the scope of work and a payment schedule and public liability insurance, with the certificate shown before work starts. Ask for a written quote, and read the reviews on the trader's profile.
Can I get an urgent building job done in London?
Yes, you can mark your job as urgent when you post it. Traders who are available now see urgent jobs first, and if nobody replies we step in. Whether someone can come the same day depends on who is free near you.
Why do some pages show prices and others do not?
We only show prices that traders have published on Arkadia, and only when enough different traders have done so for the same trade and area. Where there are not enough yet, we show no figures rather than guess.
