Frequently asked questions

Do I need planning permission for an extension?

Many single storey extensions fall under permitted development, but there are limits on size, height and position, and the rules differ for flats, listed buildings and conservation areas. Building Regulations approval is needed regardless. Check with the council planning department, or ask the builder to show you the rules that apply.

How should I pay a builder?

In stages tied to work completed, never a large sum up front. A small deposit for materials is normal. Agree the stages in writing and keep a final payment back until snagging is done.

Does membership of the FMB or a similar body mean a builder is good?

The Federation of Master Builders and similar bodies vet their members, and membership is a reasonable sign, but it is not a guarantee. References from recent customers whose work you can see, and a written contract, matter more.

How do I get a quote from builders in Welwyn Garden City?

Pick a listing on this page and send a quote request saying what needs doing and when suits you. The business comes back to you with a price and a time. It is free to ask, and no payment is taken online.

Are the builders on this page vetted?

Not yet. Listings marked Claimed have been claimed by the business and are kept up to date by them; the rest come from public records such as Companies House and Google and are marked as not yet claimed. Every listing shows its real Google rating and review count where one exists. We do not check registers or insurance yet, so ask for a Gas Safe or NICEIC/NAPIT number and check it yourself.

What should I check before I hire a builder?

Ask for a written quote and what it includes, who will do the work, whether they are insured, and any registration the trade needs, such as Gas Safe for gas work or a Part P scheme for electrics. Never pay the full amount up front.

Prices and availability are confirmed by each business. No payment is taken online, you pay the tradesperson directly.
