  • Being completely transparent in all our dealings with you and explaining the work we have carried out in straight-forward way.
  • Explaining to you the cost implication of any repair before we do it – after all, it’s your money, not ours.

"Thank you for the work carried out, your help was greatly appreciated. We were very impressed with the work carried out by your engineer, also his personality."

- Pam Hobday

"I am so impressed with the service we received from GasWise Plumbing & Heating Services (UK) Ltd. They installed a new bathroom in our house in March. They helped with the selection of the bathroom and fitted it. They were efficient ,reliable and very tidy during the process. We are pleased with the end result and would definitely use them again."

- Emily Walls

"I wanted to write to you to pass on feedback from the recent School Council Meeting, where the Chairman of the Governors put on record his thanks to all involved for the quality and the amount of work done over this summer.

To have completed the Pavilion, Lower School, Thompson Building and White Lion 6th form was a huge achievement and in terms of area of works completed makes it the biggest summer works since the Great Hall in 1938.

From a personal point of view can I also thank you for the work done in improving our school for the pupils and staff."

- Charlie Little, Bursar, Bloxham School

"Jonathan is finishing a barn annexe renovation project for a client in Oxhill. Part of the work was quite involved but it didn't seem to bother Jonathan. His men were very competent and got on with the tasks ahead. Myself and my guys like working alongside Jonathan and his men because there is good friendly banter and apart from that their work is of the highest quality. I have 100% confidence in anything they do and Jonathan will always get my call on any plumbing and heating jobs. Jonathan's business is going the right way forward and I wish him luck and prosperity in the years ahead."

- David Green

Many thanks for the bathroom works, we are really pleased with the end result, they look great.  Ben did a wonderful job!

- Mrs W Cone
My experience with GasWise was excellent as always.  The staff are always very helpful, friendly and polite.  They answer any queries I may have clearly and without jargon .  The work carried out to install my new gas fire was done efficiently and with great care.  I would happily recommend GasWise to anyone needing the services they provide.

- Jean Wilson
I would like to thank you, Lucy and your fitters for your patience, kindness and expertise in responding and dealing with my requests for help regarding my boiler problem.

Not many businesses woud be as attentive as yours, and for this I am very grateful.

- Liz Podmore
One of your engineers, a young man called Tom, came today to service our boiler and try to restore the hot water, which wasn't working. He very quickly diagnosed the problem, rang a supplier for a replacement part, serviced the boiler while he waited for it to be delivered to the house, then fitted it. He was efficient, clearly very competent and experienced, and friendly, explaining in detail what he was doing and why. Within two hours we had a clean boiler, hot water on demand, and bled radiators -- the best Christmas present possible. Tom was brilliant. Next year when we need the boiler serviced again, we'll ask for him by name. Please let him how very pleased we are.

This has been my first experience with GasWise (I used a different firm until they stopped trading last year), and I am overwhelmingly happy with your service. You've been great. 

- D Fortenberry
Thanks so much for fitting in the work on our boiler so swiftly for us. We wouldn't hesitate to recommend Gaswise to our friends or family. We were really impressed with how professionally your engineer worked to get everything working last week. He was brilliant at explaining how the new system works, too. With the -7 temperatures this week, we are very thankful that we now have a good working boiler in place!

With thanks again,

- L Hyde

We had the good fortune to be recommended to use GasWise by Buy Wise after purchasing a dishwasher. They sent Luke who was so pleasant and who worked so hard. He was so determined to do a good job. I highly recommend this firm, first class!

- Mrs M Brown 
From my initial telephone call to book an appointment I was treated in a friendly and helpful manner. The gentleman who came to service my gas boiler and check out my gas fire was pleasant, polite and efficient.  He worked tidily, especially when having to deal with some debris behind the gas fire.   He gave me good advice as to what I needed to do.   I would have no hesitation in recommending Gaswise to anyone.

- Jean Wilson
Thank you.
You were so helpful with my initial call and I'm very grateful your team found time to fit in our call.   
Engineer arrived on time which was very much appreciated, did all necessary checks and got our boiler up and running.. 
You're all Brill!  Thank you.

- Mrs S Barber
Following my initial contact with Jonathan, who gave me clear information on a date and hourly charge after I had described the job I needed doing, booked me in.  The gas engineer, Tom arrived on time and carried out the work for me, most efficiently and explained every question I had for him.  I have to say he instilled a confidence in me which is most important.  I am delighted with the work completed and extremely impressed with his expertise and for his patience with me in answering my questions and explaining everything.

Overall I am grateful to you all for your efficient and friendly approach to me as a customer, I will certainly recommend your company and indeed be in touch again when I need help.

- Mr. J Wright

Ben completed the work on Monday 11 January.  We knew Ben from previous work here, were confident that a sound installation would be achieved, and this was the case. He overcame a problem in the bedroom (some redundant micro bore pipe attached to the wall) and fixed the 3 radiators with minimal disruption. Ben tested the updated system and we are satisfied that it will perform as expected.

- Mr. B Ormerod
I just wanted to say a big thank you to you all and the team for all your help! you have all been brilliant and the service from yourselves right through to the tradesmen has been quick, friendly, professional and the work carried out has been excellent- so thank you. 
Please pass on my compliments to the rest of the team.

- Mrs G Freeland
