 Trustindex verifies that the original source of the review is Google. Very pleased with the service provided by Mason and Ian from Gas Works. Dealt mainly with Mason who did the initial survey and then the installation. He came promptly and job was finished in less time than I had thought. The area was left clean and tidy.  Would definitely recommend the company to anyone requiring tjis type of service. Thanks to Mason for his efficient and professional service.

 Trustindex verifies that the original source of the review is Google. Delighted at the service provided by Gasworks.  Found this company on the Worcester Bosch website and used for a full central heating install.  The engineers worked exceptionally hard during the hottest days in June and did a very tidy job agreeing pipe runs with me.  Would have no hesitation in using them again and recommending to all my friends/family.

 Trustindex verifies that the original source of the review is Google. Very happy with the service. Mason and Kier, the two engineers who came to install the new boiler, looked very young when they appeared at the door and because of this I was concerned at the beginning they could have not been very experienced. But I was soon proven wrong in this first impression, Mason in particular came across at the end of the installation as being very experienced. Very happy with the new boiler and with the service provided by Gasworks. I would like to praise in particular Kamila and Helen who were lovely to deal with on the phone, making me feel I was in good hands. Thank you

FAQ Some Common Questions

How quickly can you respond to an emergency callout?

We provide an emergency response service across West London during our opening hours, which are up to 22:00 on weekdays. In most cases, our engineers can be at your door within 1–2 hours, depending on your location and traffic conditions. We know heating and plumbing issues can’t wait, so we always prioritise urgent callouts.

Do you charge a callout fee for boiler or plumbing emergencies?

Yes, we do charge a call out fee. We believe in clear, upfront pricing so you know exactly what to expect before any work begins. See our Prices page for full transparency

Are your engineers Gas Safe registered and insured?

Yes. Every senior Gasworks London Engineer is Gas Safe registered and fully insured. This means we are legally qualified to work on boilers and gas appliances, and you can have complete peace of mind that all work is carried out safely and to the highest standard. There may be occasions when our apprentices in training are not yet qualified, but we will always ensure they are Gas Safe and supervised accordingly

What areas of West London do you cover?

Our team covers our core zones of West London, which are the towns of Acton, Ealing, Chiswick, Hammersmith, Shepherds Bush and West Kensington.

Our service extends throughout the Ealing, Hammersmith & Fulham, Kensington & Chelsea, Harrow, Hillingdon, Brent and Hounslow boroughs.

Do you offer fixed prices or hourly rates for your services?

We provide transparent pricing. Some services are fixed price (e.g., boiler service from £119+VAT, CP12 certificate from £115+VAT). For repairs or installations, we’ll give a clear estimate before work begins, with no hidden extras. See our Pricing page for details.

Can I book an evening or weekend appointment?

Yes. We offer flexible evening and weekend appointments for convenience.

Do you provide guarantees or warranties on your work?

Yes. All of our work is covered by a 12-month workmanship guarantee and new boilers come with a manufacturer’s warranty of up to 12 years (depending on the model and brand). This means you can have complete peace of mind knowing your repair or installation is fully backed.

Can you supply and fit new boilers, or do I need to buy one first?

We can supply and install boilers from leading brands at competitive prices, or install a boiler you’ve purchased. Most customers choose supply & fit for correct sizing, full manufacturer warranty and safe installation by a Gas Safe engineer.

Do you offer service plans or regular maintenance contracts?

Yes. We offer tailored boiler and central heating maintenance plans to keep systems safe and efficient year-round. Regular servicing helps prevent breakdowns and ensures compliance. Get in touch to discuss a plan for your home or rental property.

What happens if the problem can't be fixed on the first visit?

Occasionally, we may need to order specialist parts or carry out further diagnostics. If we can't complete the repair immediately, we'll always endeavour to provide you with a temporary solution where possible to restore heating or hot water. We'll then order the required parts and schedule a follow-up appointment at your convenience. You'll never be left without clear next steps or an estimated timeframe for completion.
