Telford's mix of housing keeps builders busy in different ways across town. You've got the newer estates around Lawley and Ketley with their timber-frame construction and warranty quirks, the older brick terraces in Wellington and Oakengates that often need repointing or damp work, and the ex-mining land around Dawley and Madeley where subsidence and ground conditions matter more than most homeowners realise. A lot of local work is loft conversions and rear extensions on 1970s and 1980s semis, plus kitchen knock-throughs on the bigger detached houses out towards Newport Road. Knowing your property type helps before you even pick up the phone, since a builder used to new-build snagging isn't always the right fit for a Victorian terrace with solid walls.
The businesses featured here are pulled from public business listings and ranked mainly by review rating and review count, with a small boost for those with a working website and listed phone number. We check each business's homepage to confirm building work is genuinely their main trade, which stops plumbers, electricians or general handymen sneaking onto a builders page. Any listing flagged as permanently closed gets removed automatically. Where you see a Trust Verified badge, that business has gone through our fuller verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information; our How We Verify page sets out exactly what that involves. For businesses without the badge, none of that has been independently confirmed by us, so it's worth doing your own homework before you book anyone in.
Before agreeing to any work, ask for a written quote that breaks down labour, materials and any waste disposal costs separately. Confirm whether they're VAT registered, since that changes the final figure noticeably on bigger jobs. For anything structural, like removing a wall or adding an extension, check they'll handle building regulations sign-off and, where needed, party wall agreements with neighbours. It's sensible to ask for photos of similar completed jobs and to speak to a recent customer if you can. Getting three quotes rather than settling on the first one is still the best way to spot if someone's pricing is out of step, either too cheap to be sustainable or padded because they think you won't shop around.
How We Select & Rate The Best Builders in Telford
Ranking is based on review rating and review count from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm building work is what they primarily do, keeping unrelated trades off this page. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have gone further, passing our full verification of trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information; see our How We Verify page for details. Other businesses here haven't been independently verified by us, and being listed isn't an endorsement. Always check credentials yourself before hiring.
Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

Small jobs like a garden wall or patio repair might run £400 to £1,200, while a single-storey rear extension on a typical Telford semi often lands between £22,000 and £45,000 depending on size and finish. Loft conversions tend to sit around £28,000 to £45,000 with a dormer. Prices shift a lot based on materials, whether structural steels are needed, and access to the site (tight terraced streets in Oakengates cost more in labour time than a detached property with a driveway). Get two or three quotes for anything over a few hundred pounds so you can compare like for like.
Do I need planning permission for an extension in Telford?
Many single-storey rear extensions fall under permitted development rights if they stay within size limits, but this depends on your property type and whether you're in a conservation area, such as parts of Ironbridge Gorge. Telford & Wrekin Council's planning portal is worth checking first, or ask your builder to confirm before work starts. Building regulations approval is separate from planning permission and is needed regardless, covering things like insulation, structural strength and fire safety.
How long does a typical extension or loft conversion take?
A single-storey extension usually takes 10 to 14 weeks from groundworks to final finish, weather permitting. Loft conversions tend to run 6 to 8 weeks if there are no complications with the roof structure. Older Telford properties with non-standard roof pitches or asbestos in the loft space can add time, so ask your builder for a realistic schedule rather than a best-case one.
What should be included in a builder's written quote?
A proper quote should break down labour, materials, skip hire or waste removal, scaffolding if needed, and any allowance for unexpected costs like discovering rotten timber or old pipework once work starts. It should also state the payment schedule, typically staged payments tied to project milestones rather than one lump sum upfront. Avoid any builder who wants full payment before work begins.
Do builders in Telford need to be Gas Safe or NICEIC registered?
Only if they're doing gas or electrical work themselves, such as moving a boiler flue or rewiring during an extension. Most builders will subcontract these parts to a registered gas engineer or electrician rather than doing it in-house. Ask who's actually carrying out that portion of the work and ask to see their registration certificate directly, don't just take the main builder's word for it.
How do I choose between builders in Telford?
Start by reading recent reviews rather than just the overall star rating, since patterns in complaints (missed deadlines, poor communication) matter more than a single bad review. Ask each builder for proof of public liability insurance and, if the job is structural, evidence of past building regulations sign-offs. Check their trading history, how long they've operated under that name locally, and ask for two or three references you can actually contact. Get everything in writing before work starts, including start dates, payment stages and what happens if the job overruns.
