Evidence to gather first
Share photos, measurements, access notes, and any relevant survey or product information so scaffolder quotes are based on the same facts.
A stronger brief helps tradespeople price the same job rather than guessing from incomplete information.
Share photos, measurements, access notes, and any relevant survey or product information so scaffolder quotes are based on the same facts.
Ask whether preparation, materials, waste removal, making good, testing, and follow-on trades are included or priced separately.
Compare timing, insurance, review quality, warranty assumptions, and how clearly each scaffolder explains exclusions before choosing a shortlist.
£500–£3,000 for small structural work, £15,000–£80,000+ for extensions and conversions

Most structural work requires building regulations approval. Planning permission may be needed depending on size, location, and conservation area status.
Low-friction quotes are not enough on their own. Push these points into writing before you let a low price or early availability become the deciding factor.
Large cash deposits before materials, drawings, or programme details are agreed.
Quotes that ignore structural unknowns but still promise a fixed total and start date.
Refusal to discuss insurance, references, or who is responsible for building control coordination.
Pressure to skip written scope, staged payments, or neighbour access planning.
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.
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.
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.
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.
