Excellent response and high quality service

A very satisfied customer
Carl was transparent, told me exactly what he was doing and why and provided a professional invoice. Carl and Grant were efficient, courteous and worked well together.

Real Service - thank you.
What a pleasure to deal with, polite, efficient with fair and reasonable costs. The office and engineers real do understand their profession. Excellent!!
Great work
I am a pensioner and had been ripped off badly by other companies in the past until I found Gasworks. I had a very bad slow leak in my downstairs toilet that had caused a lot of water damage. Carl found the leak and fixed it and also checked for other leaks. He was very courteous and considerate and cleared up afterwards. Carl is an excellent plumber which, in my experience, are hard to find. I have also used their Electrician, Oscar who is also excellent and I have used this company to have my boiler serviced every year (this year by Michael) and I can highly recommend them all. Great company and very helpful.
Endorsement Reference
On this occasion my boiler was serviced, the engineer arrived on time, communicated with me what he was doing and the work was completed as necessary. Boiler area was left in a clean and tidy state. I have used Gasworks on very many occasions for various issues and have always found them to be prompt to attend and all their work has been of an exceptionally high standard. My house presented with many unforeseen and complicated plumbing issues when I purchased it and these have all been resolved by Gasworks. Their engineers are very pleasant and helpful.

Endorsement Reference
The work on this occasion was a boiler service. It was done just as you would hope. The engineer arrived at the time we had booked, the work was done very considerately (our boiler is in the middle of our hallway so we were coming & going a lot around him, but this didn't cause any problems), and no mess at all. The booking of the appointment, and invoicing afterwards, was easy and efficient. Gasworks have been working for us for around four years and every piece of work has been to the same excellent standard - our boiler installation, boiler services, and a few other things. On a couple of occasions we've had leaks (not from any of their work, but from older plumbing) and they've come round quickly, and sorted the problem sensibly without trying to suggest lots of expensive / unnecessary work. All their engineers, and their office staff, have been unfailingly friendly and cheerful. I couldn't recommend Gasworks highly enough.
Endorsement Reference
Gasworks offer a great service. They are always polite and courteous from point of office contact to their super team of engineers who come out and carry out the work. They are clean and tidy and extremely thorough. I would highly recommend
Endorsement Reference
Installation of new pipe work for central heating and hot and cold water supply plus new radiators. The company is very professional. Provided full details and explanation of the work to be carried out. The work was completed to a high standard and within the timeframe given.

Approved plumbers on the free WaterSafe register are vetted, qualified to the water regulations and insured. Check they're listed, or find a WaterSafe-approved plumber near you.
Check the WaterSafe registerAgree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
