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 qualify for permitted development rights and bypass planning, but some don't—loft conversions, multiple storeys, conservation areas, listed buildings. Building Regulations approval is always needed. Check with the local planning authority first.

What is Building Regulations approval?

Separate from planning permission, Building Regulations ensures work meets safety, structural, energy and access standards. Plans are submitted to the local authority's control team, who inspect at key stages. Required for extensions, lofts, renovations, new builds and structural changes.

How long does a loft conversion take?

Typically 8–12 weeks for a straightforward loft conversion, depending on complexity, size and inspections. Weather, structural surprises and approval delays can extend timescales. Planning and Building Regulations approval takes 4–8 weeks before work starts.

What is the difference between solid and cavity walls?

Solid walls are single brick thickness (common in older properties), cold and prone to damp. Cavity walls have two skins with an air gap (post-1920s), better insulated and drier. Age of property roughly indicates which. Affects insulation, damp treatment and renovation options.
