Boiler help for Wrexham

Is Onyx Plumbing & Heating Ltd Gas Safe registered?
This directory does not confirm registration. Anyone working on a gas boiler in the UK must be on the Gas Safe Register, so check it directly using the company name or the postcode (LL13 8AH) before booking, and ask to see the engineer's Gas Safe ID card on the day.
What does this page tell me about Onyx Plumbing & Heating Ltd?
The registered company name, registered office address, Companies House number and incorporation date, all taken from the public Companies House register. It does not include reviews, prices, staff details, or confirmation that the company is currently trading.
Can I see reviews for Onyx Plumbing & Heating Ltd?
Not here. This is a register-based directory, not a review site. Look at independent review platforms, ask the engineer for recent local references, and confirm Gas Safe registration before any work starts.
What should I do if I can smell gas?
Turn the gas off at the meter, open windows, avoid light switches and naked flames, leave the property, and call the National Gas Emergency line on 0800 111 999. Do not wait for a routine appointment.
