  • Get a written quote and keep guarantee, insurance and payment terms in writing.
  • Run the Cowboy Checker before you commit to anyone.

How to judge a decking installer

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 whether they hold TDCA DeckMark accreditation: the only independent UK audit of decking installation workmanship (tdca.org.uk/suppliers).
  • For composite boards, confirm they are on that brand's approved installer network (Trex, Millboard, Cladco): otherwise the 25-year warranty is void.
  • Ask to see their public liability insurance certificate; £1m minimum is standard for structural outdoor work.
  • Look at completed project photos, not just star ratings, to judge finish quality and structural detail directly.

Warning signs of a cowboy

  • They ask for more than 50% deposit before materials are ordered: the most common pattern in outdoor-trade rogue complaints.
  • No project photos anywhere online: a reputable decking installer will have a visible portfolio.
  • They can't say whether your job needs planning permission or building regulations: a raised deck above 300 mm always triggers building regs.
  • They quote verbally with no written spec of materials, dimensions, or fixings: substituting cheaper timber or boards after deposit is a known scam.

Questions to ask before you hire

  • Are you on a manufacturer's approved installer network for the composite brand you're quoting, and can you pass the full warranty to me?
  • Does my deck need building regulations sign-off, and will you handle the application or advise me on it?
  • Can you show me Companies House details or proof the business has been trading for at least a few years?
  • What grade and treatment spec is the timber you're quoting: and can I see that in writing before I commit?

Frequently asked questions

How do I choose a trustworthy decking installer?
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 decking installer backed by several named sources is harder to fake than one found in only one place.
Does MyTrustedTraders rank or recommend decking installers for payment?
No. There are no ads and no paid placement. Decking installers 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 decking installer?
Confirm credentials and insurance directly with the decking installer, 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.
