Do I need planning permission for a house extension?

Many single-storey rear extensions fall under permitted development rights. However, if your property is in a conservation area, is listed, or the extension exceeds size limits, you will need planning permission. Always check with your local planning authority before starting work.

How do I know if a builder is trustworthy?

Look for verified customer reviews, proof of public liability insurance, membership of trade bodies like the FMB or NHBC, and ask to see examples of completed projects. A reliable builder will provide a detailed written quotation and a realistic timeline.

What is the difference between a builder and a groundworker?

Builders handle the above-ground structure — walls, roofs, and finishes. Groundworkers prepare the site, dig foundations, install drainage, and lay services. Many extension or new build projects require both.

How long does a loft conversion take?

A typical loft conversion takes 6–10 weeks depending on the type (Velux, dormer, or mansard). The structural work takes 2–3 weeks, followed by plastering, electrics, plumbing, and finishing.
