- Planning and building regulations: Sandwell Council handles planning applications and building control for Smethwick.

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 Smethwick?
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.
Is the water hard in Smethwick?
Most homes in the B66 postcode district are supplied by South Staffs Water, and hardness in the main supply zone is 146 mg/l (slightly hard), from 2025 to 2026 supply zone data. It varies by street, so check your postcode with your water company.
Who do I call if I smell gas in Smethwick?
Call the national gas emergency number, 0800 111 999, free at any time. Cadent runs the gas network in the West Midlands and will send an engineer to make it safe. Then book a Gas Safe registered engineer for any repair.
