Good to know

Common questions

General guidance about builders in the UK, not specific to any one business.

How long does a typical house extension take to build?

Single-storey extensions usually take 3–4 months. Two-storey can take 5–7 months. Weather, ground conditions and building control inspections affect timescale. Complexity and size of the project matter most.

Do I need planning permission for an extension?

Most single-storey extensions qualify for permitted development if they meet size and distance rules. Two-storey extensions usually need permission. Grade-listed buildings and conservation areas have stricter rules. Check with the local planning authority first.

What building control inspections happen during construction?

Inspections typically cover foundations, structural frame, roof, insulation, electrics, plumbing and final completion. At least four visits are typical. Building control must sign off before the building is legally complete.

Can I get a mortgage on a property with an extension that has no paperwork?

Most lenders will not. They require evidence of building control approval and sometimes planning consent. Undocumented work can block a sale. Lenders typically ask for these certificates before releasing funds.

What happens if bad weather stops work during construction?

Most building contracts allow extensions to timescale for weather delays. Cold, wet weather can slow concrete curing, brick bonding and external finishing. Protracted bad weather is usually factored into the contract terms.

What electrical and plumbing work needs certification?

All fixed electrical work must be tested and certified by a qualified electrician. Gas and some plumbing work also require certification. Building control will verify this during inspection. Certification protects safety and insurance.
