What to check when hiring drainage contractors in the United Kingdom

MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.

  • Confirm they cover your area and can actually come out in your timeframe before anything else.
  • Read recent reviews for reliability and turning up on time, not only the quality of the work.
  • Agree the call-out fee up front, and be wary of large upfront deposits for an emergency job.
  • Run the Cowboy Checker to confirm the business is real before you let anyone in.

How to judge a drainage contractor

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 listed on DrainSafe (drainsafe.org): the main independent competence scheme for drainage operatives in the UK.
  • Confirm they carry public liability insurance that specifically includes pollution cover, since sewage spills can trigger Environment Agency fines.
  • Look up their company on Companies House to verify they have traded under the same name for at least a few years: rogue firms frequently fold and re-register.
  • Check for Trading Standards approval via Buy With Confidence (buywithconfidence.gov.uk): contractors are criminal-record-checked and independently vetted.

Warning signs of a cowboy

  • They knocked on your door claiming to have spotted a problem outside: this is a known drainage scam pattern flagged by Trading Standards.
  • They refuse to give a written quote before starting, or quote low then add charges mid-job (for jetting, equipment, or water use).
  • They push a CCTV survey and full pipe relining before attempting a simple jet-clear first: CCTV is often unnecessary for a straightforward blockage.
  • They demand cash upfront and cannot provide a business address or company name you can verify.

Questions to ask before you hire

  • What is your call-out charge, and will you give me a written quote before any work starts?
  • Are you listed on DrainSafe or approved by your local Trading Standards Buy With Confidence scheme?
  • Does your public liability insurance cover pollution incidents and sewage damage?
  • If you find a bigger problem, will you show me evidence, such as CCTV footage, before quoting for further work?

Frequently asked questions

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