Bromley's a mixed bag when it comes to housing stock, which makes builders here a varied bunch too. You've got the 1930s semis around Shortlands and Bickley with their solid brick construction and original bay windows, Victorian terraces near Bromley South that often need underpinning or damp work sorted before anything else can happen, and newer estates out towards Petts Wood and Orpington where extensions and loft conversions are the main call. Clay soil across much of the borough means subsidence isn't unheard of, so foundations matter more here than in some areas. A lot of local work involves side-return extensions on Victorian terraces, rear extensions on 1930s semis, and loft conversions to squeeze an extra bedroom out of the roof space, given how competitive the property market is in this corner of southeast London.

The builders featured on this page come from public business listings, ranked by their review rating and how many reviews they've collected, with a modest boost for those showing a working website and phone number. We check each business's homepage to confirm building work is genuinely their main trade, which keeps roofers, electricians and other tradespeople who dabble in building work from cluttering up the page. Any listing flagged as permanently closed gets stripped out automatically. Where you spot a Trust Verified badge, that business has gone through 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 sets out exactly what that involves. For businesses without the badge, none of that has been checked by us, so it's down to you to do that homework before signing anything.

Before you commit to a builder, ask to see proof of public liability insurance and, where relevant, their qualifications or trade body membership. For structural work like a rear extension or removing a load-bearing wall, you'll need building regulations sign-off and possibly a party wall agreement if you're near a neighbour's boundary, both of which a decent builder should raise unprompted. Get written quotes from at least two or three firms rather than going with the first one, and check whether the price includes materials, skip hire and making good afterwards. Ask for references from recent jobs in Bromley or nearby, ideally something you can go and look at in person. A written contract with a payment schedule tied to project stages protects you far more than a verbal agreement ever will.
How We Select & Rate The Best Builders in Bromley

Rankings are based on review rating and review count pulled from public business listings, with a small lift given to businesses that show a working website and phone number. We check each business's homepage to confirm building work is what they primarily offer, rather than a trade that occasionally takes on building jobs. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have gone through additional checks covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information; see our How We Verify page for the full list. Other businesses haven't been independently verified by us, and appearing on this page isn't an endorsement. Do your own checks before hiring anyone.

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 →

Frequently Asked Questions

How much does a builder cost in Bromley?
It varies a lot depending on the job. A small extension or loft conversion in Bromley typically runs from around ยฃ25,000 to ยฃ55,000 depending on size and finish, while a full house renovation could run well into six figures. Day rates for a general builder sit somewhere between ยฃ200 and ยฃ350, though larger firms often price by project rather than by day. Get two or three quotes for anything beyond minor repairs, since prices can swing considerably between firms even for the same spec.
Do I need planning permission for an extension in Bromley?
Many single-storey rear extensions fall under permitted development rights, but this depends on size, proximity to boundaries, and whether your property is in a conservation area (parts of Bromley, including areas around the town centre and Bickley, have conservation restrictions). Loft conversions usually need building regulations approval regardless of planning permission status. A good builder will tell you upfront whether your project needs a planning application through Bromley Council, but it's worth checking with the council or a planning consultant yourself before work starts.
How long does a typical extension or loft conversion take?
A single-storey rear extension usually takes eight to twelve weeks once work begins, though this stretches if you're also doing a full kitchen fit-out. Loft conversions tend to run six to ten weeks depending on whether you're adding dormers or roof lights. Add extra time if your builder needs to wait for building control inspections at key stages, and factor in a few weeks either side for planning approval and material lead times, especially for bespoke joinery or roofing materials.
Should I use a builder who's a member of a trade body?
Membership of a body like the Federation of Master Builders or TrustMark can be a useful signal, since these bodies have their own vetting processes and dispute resolution schemes. It's not a guarantee of quality on its own, so treat it as one factor alongside reviews, references and seeing previous work in person. Ask any builder directly which bodies they belong to and check that membership is current rather than taking it at face value.
What should be included in a builder's quote?
A proper quote should break down labour, materials, skip hire, scaffolding if needed, and any costs for making good at the end of the job, such as redecorating or matching existing brickwork. It should also state a rough timeline and payment schedule, ideally staged against project milestones rather than large sums upfront. If a quote is vague or just a single lump figure with no breakdown, ask for more detail before agreeing to anything.
How do I choose between builders in Bromley?
Start by reading recent reviews rather than just the overall star rating, since patterns in complaints or praise tell you more than a number does. Ask to see photos or visit a recent job similar in scope to yours, and speak to a past customer if possible. Confirm the builder holds current public liability insurance and, for structural work, ask how they handle building regulations sign-off and party wall matters. Get quotes from several builders, check they match on what's included, and trust your instinct if one seems reluctant to answer straightforward questions about qualifications or past work.
