Gas Work- 23 Jun 2025
We recently completed a loft conversion and had the pleasure of working with Koli on the design and installation of our new system boiler, loft-level plumbing work, second-fix bathroom plumbing, and heating setup. From start to finish, his work was nothing short of outstanding. He’s a highly technical and capable engineer with a deep understanding of complex requirements. Despite the challenges of our build, he devised a thoughtful design and implemented it with precision and care. Every detail, from the neat copper pipework to the clean, logical layout of the system, reflects his skill and pride in his work. He was reliable, consistent, and incredibly responsible throughout the job. He's also a genuinely great guy who is easy to work with and trustworthy. We’re so happy with the final result. The quality of his work speaks for itself (see photos!). If you’re looking for someone who really knows their stuff and delivers well-planned plumbing and heating work, look no further.

Gas Work- 27 Aug 2020
Really nice genuine guy. I posted a job up in the morning and Jonathan immediately responded with his hourly rate (which is always appreciated so you don't have to shortlist before finding out how expensive they are!) and I shortlisted him and within minutes he rang to arrange to come and fix the boiler. He arrived within an hour and half, made the boiler safe by turning off the gas and stated investigating. He was honest all along the way, trying to save me money where possible. He managed to find the fault quite quickly and took the time to explain and show me what was wrong with it. He then rang up the store to make sure A) the had the part in stock so there wasn't a wasted journey and B) find the price so he could tell me the price of the part so there were no suprises. He was always very friendly, polite and explained the issues well to me, replaced went and got the relevant part and replaced it. From a boiler not working in the morning to a fixed boiler in the afternoon, great job! Would definitely recommend and will use Jonathan again for any plumbing/heating needs.

Gas Work- 1 May 2026
A very poor experience and I feel ripped-off. On sending a photo of the faulty part and discussing the issue with them on the phone they identified the part that needed changing (air release valve) and came out (arriving 45 mins late). A plumber turned up without the part, looked at the boiler and confirmed yes, that's the part needed and they would have to go get the part and come back the next day to fit it. Before leaving, the plumber called his colleague and passed me the phone and they wanted payment of £350 there and then or they would not come back and finish the job. This did not correspond with the estimated £120 they had given on MyBuilder nor with their later quoted hourly rate (he was there less than an hour on both visits). As the work was urgent (it was winter and have small kids) I made the payment. He promised to send an invoice but failed to do so despite chasing for one on several occasions. Stay clear, avoid this company and find a more reputable one.

Questions to ask a gas engineer in South London

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 South London 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 South London 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 South London 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 South London 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 South London 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 South London 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 South London

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

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