Good to know

Common questions

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

Do I need planning permission for an extension?

Most single-storey extensions under certain sizes don't need permission, but checks vary by location and property type. Lofts and two-storey work usually do. Conservation areas have stricter rules. Building control approval is always required.

How long does a loft conversion take?

Typically 8 to 12 weeks depending on size and complexity. This includes structural work, electrical and plumbing installation, insulation and finishing. Building control inspections add time at various stages.

What's the difference between a surveyor and a structural engineer?

A surveyor inspects property and identifies issues. A structural engineer designs solutions and calculations for building work. Extensions and loft conversions usually need an engineer's report before work starts.

Can I live in a property while renovation work happens?

It depends on the scale. Minor updates allow occupancy with precautions. Major renovation, rewiring or structural work may require temporary relocation due to dust, noise and safety hazards.

What is building control and why is it needed?

Building control is a legal inspection process ensuring work meets safety and building standards. They approve designs, inspect at key stages and issue a completion certificate. Required for most extensions, conversions and new builds.
