Before you get in touch. Know your budget and rough requirements. Have measurements of the property available. Check garden boundaries.

Loft Conversions

Staircase installation, flooring, insulation, roof windows or skylights, electrics, plumbing, plastering and finishing to building regulations standard.

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?

Many single-storey extensions qualify for permitted development and skip planning, but multi-storey additions, those near boundaries, or listed properties usually need it. Building regulations approval is always required.

What's the difference between building regulations and planning permission?

Planning permission controls what can be built and where. Building regulations ensure the work is structurally sound, safe and complies with energy standards. Both are often needed.

How long does a loft conversion typically take?

Most loft conversions take 8 to 12 weeks from start to completion, depending on complexity, existing services and weather. Approval and design add time before work begins.

Can I live in my house during renovation?

It depends on the scope. Small kitchen or bathroom work is manageable, but major structural work or rewiring requires areas to be sealed off. Dust and noise will be significant.

What's involved in building regulations approval for groundworks?

The local authority inspects foundations, concrete floors, drainage and backfill at key stages. They verify depths, materials, compaction and connections to the mains or septic tank meet standards.
