How to choose a builder
On bigger projects, choosing the right builder is the single biggest factor in a good result. Before you commit, check:
- Membership of the FMB (Federation of Master Builders) or TrustMark registration
- Public liability and, where relevant, structural warranties
- A detailed written quote and a realistic schedule
- Building-regulations approval and, if needed, planning permission
- A fair, staged payment plan — avoid large sums up front
- References and, ideally, a recent finished project to view

What affects the cost of building work?
Building work is quoted per project, so comparing detailed quotes matters. The main cost factors are:
- The size and specification of the work
- Groundworks, foundations and any structural elements
- The quality of finishes and fittings chosen
- Access to the site and materials storage
- Building control, structural engineer and design fees
- London labour and material rates

For larger jobs, always use a written contract and keep a retention until snagging is complete.
