Easy to do business with. The person I dealt with was very helpful and quick to respond to questions etc. The installers done a great job and left the place clean & tidy. Thanks

Warning light showing on control panel. Engineer talked me through repair procedure. Pressure fixed and system working. The fault was worrying but engineer quickly reassured me . Great service . Only minutes between first call and completed repair

Great service, quick install great team Nothing a issue and I have heating again-:-) Thanks guys

We have regretted using them for cavity wall installations and despite numerous emails/calls, they have still not fixed the issues they caused by trying to find out where the beads were continually escaping from our house. No survey was carried out on the property and on installation day, they turned up 2.5 hours late, asked to use our electrical extension lead and connected to our electricity (never asked if our equipment was safe to use). They then said they didn’t have enough material to do the job and would return the following day. Arrangements were made with work for a days leave and waited in all next day...never showed up & when DMS were contacted, they said the fitter shouldn’t have told us that as they are not in charge of timetable! Eventually got it done, however they missed a large hole and had to return.....then the mess started from October till the end of January. Our property was covered in beads continually coming out of the building. DMS did come on numerous occasions (not always at arranged times) to try to establish the leak, they topped up the beading and again it came back out. They changed the air bricks to smaller ones & now we have gaps in brickwork, to which one fitter said was too poor quality to leave, yet they haven’t been back to fix, despite emailing and verbally saying they would. They have now said the beading is escaping from our gas meter box and should have been picked up gas company, despite the meter box being installed over 20 years ago. They stuck silicone on the box 2 weeks ago and said they would return the next day to rectify the issues, yet they have never shown up nor acknowledged emails asking what is happening. CIGA have been notified asking that they don’t issue a certificate yet. Our advice to you if you are considering using them is don’t, get someone who rates customer service and can carry our work competently and does not require you to waste days off work when they don’t turn up despite arranging to. Pictures can be supplied to verify this review.

A new system had to be installed while we were away from the property so everything had to be done 'remotely'. Overall everything good and a nice and efficient new system. Particularly we must say that it looks very good - the heating unit in the cupboard looks very neat and well organised. The flat was left in excellent condition – very clean, neat and tidy. Very professional indeed.

I was promised a free service after 1 year if I wrote a good review for DMS. I've been trying to contact the company regarding this service but have been ignored for over a month. Beware anything these guys promise you.

Excellent service by both staff. Despite ferries and a few hiccups delighted at service and due to unforeseen leak almost immediate response. Back office support brill and thoroughly delighted with cost and customer service. Definitely recommend to any other Worchester Bosch oil boiler purchasers in Argyll. Straight forward no nonsence service and DMS DELIVERED !

DMS were recommended to me by my brother. From the original survey done by the person I dealt with and work carried out loft insulation by one guy and partner, underfloor insulation by another guy and Partner, heating system installed by two guys all were professional nothing was a bother to explain what their job entailed. House was as clean as before they all started, cannot fault any of the service and would definitely recommend to friends and other family. Thanks to DMS and to wee bro for recommending, from a very happy customer :)

This was a company that gave me a warm fuzzy feeling if someone can get that way about renewables. I felt confident and comfortable having this company pentetrate my walls and fill my cavity with thousands of top class silicon balls. State of the art insulation with 20 years gauranttees. DMS are great and thats a fact.The company gave me wonderfull and helpfull advice and I will happyly recommend them for many many other domestic energy products for anyones home.

I got great service from DMS. Albeit a bit persistent to start with. They were very patient with me as I had to wait for a HEEPS loan and they knew exactly what the procedures were. Work done in one day and all great!

Phoned the company and spoke to a guy. He was great communicator and kept his word on what he said that goes a long way. Boiler was fitted and all the other stuff done all in the one day. Got a electric box updated as well So very happy. If your contacting this company is recommend you talking to him

Excellent service from DMS from start to finish. I needed a new boiler installed at a property I rent out. My tenant had no hot water, so I needed quick action. With products and prices excellently explained, then firmed up on him talking to my tenant. I was able to confirm the order over the weekend with DMS. They then sent in a technician to install on the Tuesday. My tenant was delighted at the fast service - all in all 5 days from initial call to instillation - and so was I as DMS also came up with the best prices as other quotes came in. I would well recommend DMS on both service and price, and have already recommended them to my Tenancy Management Company.

DMS have been friendly, helpful and efficient from start to finish Had several quotes and realised that they were prepared to arrange a package that suited our needs. The sales manager, was particularly helpful Our installation team were excellent, from the technical visit right through to completion of installation and explanation of the system. They were happy to answer any questions. Would happily recommend this company, thanks to you all.
