Bad plumbing experiences are unfortunately common. Overcharging, poor workmanship, and disappearing tradespeople are real risks. Here's how to protect yourself.
Non-negotiables for gas work
Any plumber working on gas appliances, boilers, or gas pipework **must** be on the Gas Safe Register. This is a legal requirement, not optional.
You can verify any engineer by:
1. Asking for their Gas Safe ID card (every registered engineer carries one)
2. Checking at [gassaferegister.co.uk](https://www.gassaferegister.co.uk) using their name or registration number
Working on gas without Gas Safe registration is illegal and creates a serious safety risk. Never hire someone who offers to do gas work 'off the books' regardless of price.
Reviews and reputation
Look for engineers with a consistent track record of positive reviews across multiple platforms:
Be wary of businesses with only a handful of reviews all posted within a short period.
Written quotations
Always get a written quotation before work begins. This should specify:
Verbal quotes are difficult to dispute if the final invoice is higher than expected.
Check for public liability insurance
A reputable tradesperson carries public liability insurance. This protects you if they accidentally damage your property during the job. It's reasonable to ask for evidence of this.
