I used the Welwyn Garden Office. Excellent price (I had several quotes) Good workmanship and excellent friendly fitters. Final Invoice exactly the same as the Estimate 5 stars. Very happy with the company and would certainly use again.

Gas Works Plumbing & Heating - Central Heating and Plumbing Works I have used Gas Works Plumbing and Heating a number of times in these last recent months. I have found them to be excellent and would not hesitate in making recommendations for anyone requiring gas, plumbing and central heating services. I can safely say they have an excellent knowledge base with all aspects of central heating and general plumbing. Gas Works PH fully upgraded our central heating systems with the Honeywell Evohome Wireless systems which allows you to take full individual control of radiators via the Evohome App, which works perfectly. I found their install teams to be highly professional and approachable and always respected our home by keeping their works clean and tidy at all times. Once we had our new system fitted they showed us how it worked and were available on the telephone to answer any queries or problems. In addition to the central heating upgrade we also had a water pump fitted to our down stairs hot water to improve the water pressure. Unfortunately this water pump failed after about 10 months of use and so I contacted Gas Works PH regarding this. Gas Works PH were excellent, they did not hesitate to look into this and ultimately they arranged for a new pump to be delivered from the manufacturer which they came and fitted a few days later without question. Many thanks to Gas Works Plumbing and Heating and all their install guys that came to our home!

Brendon did a wonderful job setting up our central heating system, very professional, very knowledgeable, very cheerful. Excellent value for money. A pleasure to do business. I wholeheartedly recommend Gasworksph for a thorough job.

I've used Gasworks thrice in the last two years, based on a recommendation from a neighbour. I can't fault the knowledge, friendliness and professionalism. It's a relief to find reputable heating and plumbing engineers, at a competitive price! Thanks to all the team!

First class, A* Service. We had several Heating and Plumbing issues which were all resolved very quickly and professionally. Our visiting engineer, Michael, was on time, friendly and clearly very experienced. The communication with the company was excellent, they gave sound professional advice and I would highly recommend them.
