I've worked for leading Plumbing and Heating companies across cardiff. Boilers, bathrooms, renovations, leaks... you say it, if it's to do with Plumbing I've probably done it. I've decided to make the leap of being self employed. I hope this will not only better myself and my trade but allow me to have control over my own time so I can see my children growing up! Please get in touch for any work needed. Kind regards. Lawrence

Plumbing- 27 Apr 2018
Owain quoted me for the job ( outside tap new install ) and told me he lived locally. On the Monday he called in to see what he needed for the job and told me that he would be here on the Wednesday aftertnoon. He also phoned me to let me know what time he was going to be at my home. Throughout the job he explained to me where and what he was doing which was great! Owain cleaned up during the job and made sure I was happy with his work. He actually showed me what was done and his work ethics are great. I am very pleased with the way he carried out the job, he was polite and easy to talk to. There would be no hesitation in recommending Owain for his work. The very reasonable quote was the actual price I paid. Thank you

Central Heating- 24 Jan 2026
Had a new radiator fitted before Christmas. Initially it looked fine, but it was connected to the wrong feed in our dual-zone heating system. The radiator works intermittently due to an airlock, affecting heating throughout the house, with gurgling and hissing noises. He also left holes in the wall from an initial failed mounting attempt, and the Hive installation took multiple visits to complete. Several attempts were made to have the issues fixed. Messages were ignored, appointments were cancelled late, and on the final arranged date he didn’t turn up or respond. This has been particularly difficult as we have a toddler and a newborn in the house. We’re now having to pay another plumber to put it right. Very disappointing.

Questions to ask a gas engineer in Cardiff

Choosing the right gas engineer is essential, not just for quality but also for your safety. You can be sure you find a suitable gas engineer by asking the right questions.

Some key questions you should ask before hiring a gas engineer in Cardiff include:

Are you Gas Safe registered?

This is the most important question to ask. Only Gas Safe–registered engineers are legally permitted to carry out gas work in the UK. Ask to see their Gas Safe ID card, which lists the types of gas appliances they’re qualified to work on.

What experience do you have with this type of job?

Whether you need a boiler installation, central heating repair, or a gas safety check, look for someone who has completed similar work recently. Experience with your specific appliance brand or system can help avoid costly mistakes.

Can you provide a detailed written quote?

A professional gas engineer in Cardiff should offer a clear, itemised quote covering labour, parts, call-out fees, and VAT. This avoids unexpected costs and lets you compare prices easily between engineers.

Do you offer any warranty or guarantee?

Ask whether the engineer guarantees their workmanship and if the manufacturer provides a boiler or parts warranty. Many gas engineers in Cardiff back their work for 12 months or more.

Do you offer emergency call-outs?

Gas leaks and heating failures can happen at any time. Ask if the Cardiff gas engineer provides 24/7 emergency cover, and confirm how quickly they can attend.

What are your charges for emergency or out-of-hours work?

Many Cardiff gas engineers charge a higher rate for evenings, weekends, or emergencies. You should be aware of these rates in advance to avoid unexpected costs if something goes wrong outside normal working hours.

Will you provide a Gas Safety Record after the work?

For installations or inspections, your Cardiff gas engineer should issue a Gas Safety Record (CP12) confirming the appliance or system has been checked and meets legal safety standards. Be sure that the engineer you choose will do so, if required for the job.

FAQs: Frequently asked questions when looking for gas engineers in Cardiff

How do I check if a gas engineer is Gas Safe registered?

You can verify any gas engineer in Cardiff’s registration by visiting the Gas Safe Register website. You can also ask to see their Gas Safe ID card, which shows their licence number and the types of gas work they’re qualified to carry out.

How long does it take a Cardiff gas engineer to install a new boiler?

A straightforward boiler replacement typically takes one to two days. More complex upgrades (like moving a boiler or updating pipework) may take longer.

Do I need a gas engineer in Cardiff to conduct an annual gas safety check?

Yes, it’s recommended for all homeowners and legally required for landlords. Annual checks keep appliances safe, efficient, and compliant with UK regulations.

Can I ask a plumber in location to work on gas appliances?

Only if they are Gas Safe registered. Some plumbers in Cardiff hold dual qualifications, but unless they appear on the Gas Safe Register, they cannot legally work on gas installations or appliances.
