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 rear extensions under 4 metres and two-storey extensions under 3 metres qualify for permitted development and don't need permission. However, planning permission is required in conservation areas, listed buildings, and for larger extensions. Check with the local planning authority first.

How long does building regulation approval take?

Building control typically takes 5–10 working days to approve plans after submission. The actual build inspection process happens at foundation, structural, and completion stages. Start the approval process early, as it runs parallel to planning but takes time.

What is a structural engineer's report and why is it needed?

A structural engineer assesses whether proposed changes to a building are safe and feasible. Required for loft conversions, extensions creating large openings, and renovations affecting load-bearing walls. The report tells you what support is needed and confirms the design is sound.

What makes a loft conversion fail building inspection?

Common failures include inadequate roof insulation, poor ventilation, joists unable to support a floor, headroom under 2.2 metres, inadequate fire safety routes, and insufficient window openings. These must all meet current building standards.

How do you protect a property during renovation?

Builders use dust sheets and temporary barriers to seal off work areas, protect fixtures and floors, and manage waste removal daily. Temporary hoarding protects the exterior. Good site management reduces disruption and protects existing structures.
