Above & beyond
My boiler stopped working, no heating or hot water on Christmas Eve. I phoned after lunch on the off chance someone would still be working. Darren was fantastic & was able to talk me through what to do over the phone to get everything working again. Great service, so kind & helpful. Thank you!

Fast, efficient and friendly
We have used DHS for some years now. They installed our current boiler and have serviced it annually since. Making an appointment is always easy. Emails and phone calls are professionally handled and always courteous and friendly. Very flexible around appointments and accommodating if a change is needed. Work carried out with skill and efficiency every time. Very approachable staff who are happy to offer advice/answer questions.

Excellent Service As Usual
Turned up on time, was thorough in teh work required checking out the loft exhaust/air intake pipes, testing the gas pressure at the meter. Issues with a parts failure that required Bosch Engineer to be arranged and left within the hour.

First rate Heating company
I have been using this company for 15 years. They are a longstanding local business. They have regularly serviced and occasionally repaired or upgrade our gas heating system. They arrive on time, head office communicates well if they have had to change appointment. I have had helpful verbal advice from the engineers in the office when needed that has helped me resolve problems. The engineers are universally polite, knowledgeable and efficient. Each year I have an interesting discussion with the engineer not only about our system but also the up to date developments in alternative green and efficient ways of heating houses. I have a scientific background and the engineers know their stuff! When our boiler has broken down they respond quickly. I have never been overcharged. I am not easy to please.

Landlord gas safety check and boiler service
Very good service. From the initial helpful phone call to arrange appointments to being kept informed the whole time about what was happening and when, the customer service level was very high. When there was a slight issue my end re access this was resolved efficiently and without fuss. Very good value too when the boiler service option is taken alongside the landlord safety check. I have already recommended DHS to others and will continue to do so.

Friendly, reliable service over many years.
Have used this local company for two decades or thereabouts, for services ranging from the installation of our CH boiler and annual servicing, to a variety of smaller domestic repairs. Engineers and plumbers who have attended have been unfailingly prompt, courteous and efficient. Charges are fair and reasonable by the standards of the industry. I can recommend them with confidence.

Prompt and effective service
DHS installed our new boiler and we've been happily using them for servicing since. They last came out at very short notice when we stopped getting hot water and promptly identified the fault (a failed heating valve) and replaced it.

Great job of annual servicing of gas appliances
As in previous years, DHS did a throughly professional job. The gas engineer came within the scheduled time period and serviced our Worcester Bosch boiler as well as the gas burner in the living room. He spent quite a bit of time in completing the job. I also liked the after sales service DHS provided in answering questions I had. I do hope to continue using their services in the future.

DHS removed an old radiator in the kitchen/diner, prior to decorating, and came back after decorating to fit a new one.
The 2 engineers turned up on time, were cheerful, polite, respectful, and professional. They did the job well, tested the central heating system, and cleared up after themselves. The cost was reasonable.

Gas Boiler Annual Service
DHS installed my boiler in 2018 and have serviced it annually ever since. Their engineers seem very thorough, competent and considerate, and I have always been very happy with their work. When you phone them, the phone is answered promptly by a real person, who is also friendly and helpful!

Efficient and friendly service
I have used DHS to install my boiler in March 2021 and they have serviced it every year since then. They run a very efficient service, easy to contact and the staff are very helpful and friendly. I like using a local firm and will use DHS for as long as I have a gas boiler to be serviced.

Boiler service - just one of the things DHS have done for us over the years
This most recent visit was for the annual boiler service of our Worcester Bosch boiler. DHS also looks after the boiler for our elderly parents, and over the years, has solved plumbing issues and installed a gas stove (looks like a wood burner) for us. We would recommend them for all of the work they have done for us. Everyone we have dealt with - from Marie and Lin in the office, to the engineers we see - is very friendly and professional. We think DHS has got the customer service just right, and we would not dream of asking anyone else for assistance with gas and plumbing work.

Good work
The annual boiler service was carried out efficiently and the paperwork arrived promptly the next day. A courtesy call was made when the engineer was running late which was very helpful. First class, friendly, professional service.

Happy I switched from British Gas
After our boiler died last year I contacted DHS on a friend's recommendation. They installed a new Vaillant boiler and have just done it's first annual service. Every part of the process has been smooth and comfortable. The installer and the service engineer were both prompt, polite, tidy, efficient and helpful, and the office communication has been excellent. The prices charged are very good value. Very happy with everything from this company and will recommend to everyone.

Great company, great job
The job entailed replacing the WC in the first floor bathroom along with replacing a damaged floorboard beneath the WC. The engineers arrived on time and were friendly and polite. On lifting the damaged floorboard it was discovered that additional support was required before fitting the new board. This was completed at no extra cost. All the work was carried out in a professional manner and the area was left clean and tidy. I was kept informed of progress and when the water needed to be switched off and back on. Very happy with the end result and would highly recommend DHS for any plumbing jobs. Will definitely use again.

'Mobility Bathroom' beautifully constructed and finished
DHS was by far the most efficient of the 3 WTT bathroom fitting firms we approached and gave us a very reasonable estimate for a fairly complex job, of creating a 'Mobility Bathroom' in an under-eaves location. Ian Johnstone's planning was exact, even though installation had to be postponed twice because of very late delivery of the walk-in bath from Victorian plumbing, (whom we can't recommend). The installation team was superbly led by Ricky, and was first-class from start to finish, arriving on time and always most courteous. The final clean-up was impeccable and all rubbish and detritus cleared away. The result is a joy to behold and to use. We highly recommend DHS!
