Looking for a builder near you in Bromley?
Use the project postcode and describe the property, proposed work and stage you are at. Access and logistics can differ greatly between a tighter town-centre property and larger homes around Chislehurst, Hayes, Bickley, Orpington or West Wickham, so delivery space, skips, neighbours and approvals should be clear before builders price the job.
Building projects large and small
What can a Bromley builder help with?
A general builder may take on anything from masonry repairs to a multi-trade renovation. Larger projects are easier to compare when every builder receives the same drawings, specification, structural information and responsibilities.
Renovations & refurbishments
Whole-room or whole-house improvement projects involving strip-out, repair, reconfiguration, making good and coordination between several trades.
Structural alterations
New openings, wall alterations and structural supports where the work follows appropriate design, calculations and the required approval route.
Brickwork & masonry
New walls, repairs, repointing, steps, blockwork and other masonry where a general builder or brickwork specialist is appropriate.
Conversions & reconfiguration
Garage, loft-adjacent or internal reconfiguration projects that change how existing space is used, subject to design and permissions.
General building repairs
Local masonry, structural and fabric repairs, making good after other trades and building work that goes beyond a typical handyman visit.
How much does a builder cost in Bromley?

~£9,949/jobaverage Bromley general-building job
£5,168–£16,998typical Bromley general-building range
Indicative guidance checked August 2026. Checkatrade currently shows general building services in Bromley at about £9,949 on average, with a typical range around £5,168–£16,998. Larger projects should be compared from drawings, scope, materials, access, waste, specialist trades and programme rather than a single average.

Give every builder the same project information
A low headline figure is difficult to judge if one builder includes scaffolding, waste, structural steel, specialist trades and making good while another does not. Standardise the information before comparing totals.
- Share drawings, dimensions, structural information and specifications you already have.
- State which permissions or approvals have been obtained and who is expected to manage inspections or paperwork.
- Explain access for deliveries, skips, scaffolding and materials, including shared or narrow routes.
- Ask each builder to state exclusions, VAT where applicable, payment stages, programme and how variations will be agreed.

Access and planning context can change a project
Building logistics vary between denser streets and larger suburban plots. Delivery access, parking, skips, scaffolding and neighbour boundaries should be considered before a programme and quote are finalised.
Planning and Building Regulations are separate checks. Some work may fall within permitted development while other projects require planning permission, Building Regulations approval or both. Check the property and proposal with the relevant official guidance before construction.

What should you check before hiring a builder?
For substantial work, compare more than the total price. Look at relevant experience, the clarity of the written scope, how the project will be managed and what happens when design or site conditions change.
Comparable project experience
Ask for recent examples and references from work similar in scale and complexity. Extensions, structural alterations and full renovations demand different planning from small repairs.
Contract, insurance & payment stages
For larger work, agree the scope, insurance, programme, variation process and staged payments in writing. Avoid vague arrangements that make inclusions hard to judge.
Approvals and responsibilities
Clarify who is responsible for drawings, structural design, planning matters, Building Regulations, inspections and completion paperwork before work begins.
Builder plus specialist trades
Make sure the right Bromley specialists are included
A builder may coordinate a renovation or extension, but electrical, plumbing, roofing and finishing work still needs the right trade and, where relevant, the right qualifications.

How much does a builder cost in Bromley?
Current Checkatrade Bromley guidance shows general building services at about £9,949 on average, with a broad range around £5,168–£16,998. Larger extensions and conversions can be much more.
Do I need planning permission for an extension in Bromley?
Not every extension needs a full planning application because some work can fall within permitted development rights, but the answer depends on the property and proposal. Check official planning guidance before work starts.
Is Building Regulations approval the same as planning permission?
No. Planning and Building Regulations are separate systems. A project may need one, both or neither depending on the work.
Can heritage or local controls affect building work in Bromley?
They can. Conservation, listed-building and other local planning controls may affect external alterations, so check the property’s status before finalising the design.
Are the builders verified?
Tradespeople using our partner service are verified with official identification, email and phone details. You should still review profiles, comparable project experience, insurance and the full quote.
Do I have to accept a builder quote?
No. Posting the project does not oblige you to hire anyone. Compare the scope, experience, programme, contract terms and price before choosing.
