Extensions & additions
Single- or two-storey extensions, side or rear additions, porches and other projects involving structural work and coordination with other trades.
Builder Sutton
Planning an extension, renovation, structural alteration, conversion or substantial repair? Post the project once and suitable builders covering your Sutton postcode can get in touch. Compare relevant experience, scope, programme and price before deciding who feels right for the work.
Sutton projects can range from alterations to period and interwar homes around Cheam, Carshalton and Belmont to extensions on later suburban houses and refurbishment of town-centre flats. Rear access, parking, shared boundaries, trees and existing extensions can all change deliveries, skips and scaffolding. Planning status matters too: conservation areas and Sutton’s Article 4 Directions can remove permitted-development rights for some work.
Building projects large and small
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 statement of responsibilities.
Single- or two-storey extensions, side or rear additions, porches and other projects involving structural work and coordination with other trades.
Whole-room or whole-house improvement projects involving strip-out, repair, reconfiguration, making good and coordination between several trades.
New openings, wall alterations and structural supports where the work follows appropriate design, calculations and the required approval route.
New walls, repairs, repointing, steps, blockwork and other masonry where a general builder or brickwork specialist is appropriate.
Garage, loft-adjacent or internal reconfiguration projects that change how existing space is used, subject to design and permissions.
Local masonry, structural and building-fabric repairs, making good after other trades and work that goes beyond a typical handyman visit.
Prices depend on the exact scope, materials, access and complexity. Current Sutton data gives useful local reference points:
Indicative guidance checked August 2026. Checkatrade currently shows general building services in Sutton at about £9,949 on average, with a typical range around £5,168–£16,998. Its Sutton extension data averages about £38,253, so larger projects should be compared from drawings, scope, materials, access, waste, specialist trades and programme rather than one headline average.
Comparable quotes start with a comparable brief
A low headline figure is hard 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.

How it works
Describe the work once and let suitable local tradespeople who cover the postcode decide whether the job fits their experience and availability.
Enter the Sutton postcode, describe the work, project stage, drawings or approvals you have and your preferred timing.
Your requirements can be matched through our partner network, and up to 3 local tradespeople can contact you about the work.
Compare relevant experience, what is included, timing and price before deciding who to hire.
Choose with confidence
Compare more than the headline price. Relevant experience, a clear written scope, sensible communication and appropriate insurance or paperwork all help you choose with more confidence.
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.
For larger work, agree the scope, insurance, programme, variation process and staged payments in writing. Avoid vague arrangements that make inclusions hard to judge.
Agree timing, access and how changes will be handled. Where testing, certification, permissions or specialist paperwork applies, clarify who is responsible.
Builder and related trades
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. Ask who will carry out each part and who remains responsible for coordination.

Not every extension needs a full planning application because some work can fall within permitted development rights, but the answer depends on the property, proposal and local restrictions. Sutton Council notes that conservation areas and Article 4 Directions can restrict permitted development.
It removes permitted-development rights for certain alterations and additions to specified houses and their curtilages on named roads, so planning permission will usually be required for those works.
No. Sutton Council says a number of properties across the borough have had permitted-development rights withdrawn for roof alterations, including extensions and dormer windows.
