Martyn removed the bathroom suite, tiled the floor and then refitted the bathroom suite. I was really impressed with it. It was quite a difficult job - the bathroom is very small and in fact one tradesman could not cope with it. We bought tiles and Martyn came and laid these beautiful tiles for us after preparing the floor. I am absolutely over the moon with it - he has done it really well, I am really impressed. I would definitely recommend him. The kitchen floor is next on the list!

Mario was great, he capped the old pipe off at the mains and removed the redundant pipes in the house. He was so swift we didn't notice he'd done the work while we were doing other work in the room! We'll be calling him again in future.

Questions to ask a gas engineer in Llanelli

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 Llanelli 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 Llanelli 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 Llanelli 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 Llanelli 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 Llanelli 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 Llanelli 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 Llanelli

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

You can verify any gas engineer in Llanelli’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 Llanelli 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 Llanelli 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 Llanelli hold dual qualifications, but unless they appear on the Gas Safe Register, they cannot legally work on gas installations or appliances.
