How to judge a loft conversion specialist

Independent, no-ads guidance. The trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each trader’s public evidence above.

Verify before you hire

  • Check they are on the FMB (Federation of Master Builders) register at fmb.org.uk: it means independent vetting, insurance, and credit checks.
  • Confirm they carry Public Liability insurance and ask whether their subcontractors (electricians, roofers, structural engineer) are also insured.
  • Ask for the building-control completion certificate from a previous loft job: proof the council actually signed off the work as legal and safe.
  • Look up their company on Companies House: a firm under two years old with no track record is a serious risk on a major, high-cost project.

Warning signs of a cowboy

  • No FMB, TrustMark, or similar independent vetting: any established loft specialist should have at least one.
  • Asking for a large upfront deposit in cash with nothing in writing: a legitimate firm will give you a staged-payment contract.
  • Glossing over building regulations or saying you 'probably don't need planning' in a conservation area without actually checking.
  • Reviews that only mention general building work with no loft conversions specifically: generic builder experience is not loft experience.

Questions to ask before you hire

  • Can you show me photos and addresses of loft conversions you've completed: ideally similar to mine in property type and area?
  • Who handles the building-control application and who is the structural engineer for the floor and ridge beam design?
  • My property is terraced: will you manage the Party Wall Notice process, or do I need to arrange that myself?
  • Are you registered with NHBC or LABC Warranty so I can get a 10-year structural warranty that satisfies my mortgage lender?

Frequently asked questions

How do I choose a trustworthy loft conversion specialist?
Compare the public evidence on each profile: how many independent reviews they have and across how many named sources, the rating and how recent it is, any credential evidence, and the company status. A loft conversion specialist backed by several named sources is harder to fake than one found in only one place.
Does MyTrustedTraders rank or recommend loft conversion specialists for payment?
No. There are no ads and no paid placement. Loft conversion specialists are ranked only by the strength of independent public evidence. No one can pay to rank higher, add a badge, or change their reviews.
Where do the reviews come from?
They're imported from named public review sources and always shown with the source named. They aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
What should I check before hiring a loft conversion specialist?
Confirm credentials and insurance directly with the loft conversion specialist, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence. It doesn't replace your own checks before you hire.
