Gloucester's housing stock keeps local builders busy with a very particular mix of work. There are the Victorian and Edwardian terraces around Barton, Tredworth and Linden, where lime-rich old brickwork, tired chimneys and damp problems come up again and again. There are 1930s semis in Hucclecote and Longlevens that suit rear extensions and loft conversions, and there are plenty of newer estates around Quedgeley and Kingsway where the jobs tend to be kitchen knock-throughs, garage conversions and patios. Gloucester also sits on the Severn floodplain, so ground conditions vary a lot. Clay in the lower parts of the city can mean deeper foundations, and some areas near the docks and the river need extra thought about drainage and damp-proofing.

The businesses on this page are drawn from third-party business listings and ranked by public review rating and review count, with a small lift for those that show a working website and phone number. We read each business's homepage to confirm that builders work is what they primarily offer, which keeps unrelated businesses off the page. Permanently closed listings are removed automatically. Where you see a Trust Verified badge, that business has additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page has the full list. For anyone without that badge, we haven't independently verified them, so those checks are yours to make before you book.

Get at least two or three written quotes, and make sure each one breaks the job down properly rather than giving a single lump sum. Ask to see proof of public liability insurance, and ask whether the builder holds relevant trade accreditation. Find out who will handle Building Regulations applications and who is responsible for any party wall notices if you share a boundary with a neighbour. Agree a payment schedule tied to stages of work, not big sums up front. A sensible deposit is usually small, and you should hold back a final payment until you're happy with the finished job. Ask for completion certificates and any warranties in writing, and keep them somewhere safe for when you sell.

Frequently Asked Questions

How much does a builders cost in Gloucester?
It depends on the job. A single-storey rear extension typically runs from about £1,800 to £2,500 per square metre, so a 20 square metre extension might land between £36,000 and £50,000. A loft conversion with dormer usually costs £35,000 to £60,000, while smaller jobs like a garden wall, a new patio or replastering a room sit in the hundreds to low thousands. Day rates for a general builder tend to be £150 to £250. Spec, access, ground conditions and whether the job needs structural steel all push the price up or down. Getting two or three quotes is normal, and any builder worth hiring expects it.
Do I need planning permission or Building Regulations approval for an extension in Gloucester?
Many single-storey rear extensions fall under permitted development, but not all. Conservation areas, such as parts of the city centre and Kingsholm, have tighter limits, and flats and maisonettes don't get the same rights as houses. Building Regulations approval is a separate matter and is needed for almost any structural work, including extensions, loft conversions and removing load-bearing walls. Gloucester City Council's building control team can advise, or you can use an approved private inspector. Ask your builder who is handling the application, and don't start work until it's sorted.
How long does a typical building project take?
A kitchen knock-through with steelwork might take two to three weeks. A single-storey extension usually takes three to five months from groundworks to finish, and a loft conversion about eight to twelve weeks. Weather matters more than people expect, especially for foundations and brickwork on clay-heavy ground near the Severn. Ask for a written programme with stage dates, and build in some slack. Good builders are open about delays and tell you early when something unexpected turns up behind a wall.
What should be in a builder's quote?
A proper quote lists the scope of work in detail, materials with allowances for items you'll choose yourself, labour, skips and waste removal, and what's excluded. It should state the payment schedule, the start date and expected duration, and say whether VAT is included. Beware of vague quotes with a single total. If a price is far lower than the others, ask what's been left out, because that's usually where disputes begin.
Will the builder deal with my neighbours and party wall issues?
Not automatically. If your work involves a shared wall, building on the boundary or digging near a neighbour's foundations, you may need to serve a party wall notice under the Party Wall etc. Act. That's normally the homeowner's responsibility, though a good builder will point out when it applies. In the tight terraces around Tredworth and Barton, it comes up often. Chat to your neighbours early, tell them about noise and skip placement, and it'll save friction later.
How do I choose between builders and check they're legitimate?
Start with the paperwork. Ask for proof of public liability insurance and check the policy covers the type and value of work you're planning. Ask whether they hold relevant trade accreditation and check it with the issuing body directly. Look up the company on Companies House if they trade as a limited company. Read online reviews for patterns, not just the star rating, and ask for addresses of recent jobs you can visit. Check how long they've been trading. Get everything in writing, including a contract, and never pay a large deposit upfront. If a builder gets awkward about any of this, move on.
