Whether it's a leaking radiator or a misbehaving boiler, you'll eventually need a Chelsea plumbing professional to sort it out. But not every tradesperson delivers on their promises — some don't show up or leave jobs unfinished, even cause more problems than they solve. So how can you make sure you're letting the right plumber into your home? Here's what to check before booking anyone in.

Make sure they're Gas Safe registered.

Any plumbing engineer working with gas must be registered with the official Gas Safe Register. This proves they've passed the required safety training and are legally authorised to work on boilers, water heaters, and other gas appliances.

If there's even a chance your plumbing issue is connected to your heating system, double-check that your tradesperson holds Gas Safe credentials. It's the best way to ensure your home stays safe and compliant while the work is carried out.

Expect clear pricing and written agreements.

Reliable plumbers no longer scribble vague prices on scraps of paper. Professional tradespeople now provide clear written quotes and contracts — whether that's sent by email or printed out in writing.

Here's what to expect from a trustworthy Chelsea plumbing engineer:

  • Written terms and conditions that outline what's covered
  • A breakdown of the materials and services included
  • A clear explanation of the issue and what needs to be done
  • A straightforward summary of the total cost, along with the payment schedule

This level of transparency protects you from surprise fees and makes it easier to hold someone accountable if anything goes wrong.

Are they insured?

It's important to choose plumbers who are fully insured and backed by a trusted company like WPJ Heating. When Chelsea plumbing engineers are employed directly, you can feel confident that they're properly qualified and covered for every job they take on.

Many installation companies rely on sub-contractors, which introduces a lot of uncertainty. You might end up with someone whose qualifications aren't verified and who is uninsured. It can also affect the quality of work, especially if the job requires multiple visits or ongoing follow-ups. With subcontracted labour, there's no guarantee who will turn up or how experienced they'll be.
