Great bathroom installation
We decided to get a quote for SGS bathroom installation after purchasing our new bathroom from Island. Colin was professional and clearly had a lot of experience when he came out to quote. Having never done anything like this before we were reassured by SGS depth of expertise and experience backed up with their 10 year warranty so decided to go with them and we were pleased that we did. Phil the main fitter arrived on time each day and completed the job to a standard that exceeded our expectations. He was on hand to offer advice / guidance on the decorating we needed to do after. He left everything tidy each day, explained what his plans etc. Him, Colin and James the plumber are an asset to SGS. We won’t hesitate to use SGS for other works around the home in the future.

New Bathroom
We purchased a replacement Bathroom from Island Bathrooms and elected to have it installed by their recommended installer, SGS. The installation was completed in the time estimated to a very high standard, despite the challenges faced when removing the old bathroom. When faced with challenges the depth of experience that could be brought to bear was extensive, and resolved the problem. I would not hesitate to recommend SGS for the installation of a heating system, bathroom or any electrical or plumbing related work. You will save money in the long term, because you can be confident that the work will be completed to a high standard.

Boiler installation
Had a new boiler installed yesterday by Mark at SGS. He arrived on time and took the amount of time we were told. He was very courteous and polite. Particularly liked that he protected all carpets before he started. Checked with us throughout the work and left the house without any evidence of having been (apart from the new boiler of course). When he was finished he went through all the instructions with us and made sure we were happy with everything. Really no surprise that all went well as SGS have always done a first class job. Thank you all, much appreciated

Complete Bathroom Refit
Our bathroom was old and needed a complete renovation. SGS responded quickly, provided a competitive quote, and scheduled the work to be finished before my retirement. Jeff from SGS arrived on time daily, worked hard for two weeks, and provided excellent service, resulting in an outstanding new bathroom. My extended family has given us numerous compliments about the new bathroom. I want to thank everyone at SGS who was involved in completing this project on time. Well done!

Clean and efficient work to unblock kitchen sink
SGS visited to unblock the kitchen sink, after a different company had tried and failed. The plumber arrived on time and worked efficiently, but more important was effective in unblocking the sink and left the area clean and tidy. I have no hesitation in recommending this company.

Saved us from cold showers
Having had our usual plumber - not based in the area - only promising a booking in a couple of weeks we decided we couldn't wait and face further low hot water pressure. SGS had come to provide previous quotes for Solar and HVAC we'd been impressed by their knowledge and helpfulness. I completed their form out-of-hours in the evening, got a call the next morning and a plumber was with us by the afternoon. Within an hour the issue - severe blockage in different sets of pipes - the issue was fixed. Costs were fine; certainly in line with what I was expecting.

Solar panel installation
Great service from start to finish. A detailed initial survey followed by a competitive quote. Work started within a couple of weeks of the survey and they fitted their work around other jobs that were being done at the same time. 15 solar panels, battery and inverter all fitted in a couple of days (they would have completed the job in a day had the weather not been truly atrocious!). Work finished neatly and tidily. Would definitely recommend them.

Solar PV Installation
SGS carried out the installation of our Solar PV system. They were recommended by a Yorkshireman who had SGS instal the same system for him, he was so pleased he almost broke into a smile. Even though we are about 150 miles from SGS’s area of Ops they agreed to instal for us. Throughout the project, communications with the Project & Renewables Manager were good and update communication passed both ways prior to the instal date. The team arrived early day 1 and went about their business without complaint enduring the usual poor Welsh weather gave them. Their work is very neat and looks professional – probably because they send qualified electricians with many years’ experience unlike other installers who, we find, have only done a short instal course. The instal went well with a second confirmatory check the day after it was commissioned to ensure no faults had occurred overnight. A full brief was given prior to clearing and sweep-up and departure. SGS quote was reasonable – and quality – be it labour or the equipment used. Highly recommended.

Improper Call-Out Charge
Requested a visit from an engineer to prepare an estimate to repair and reposition our gas boiler and cylinder. Estimate received same day but followed up several weeks later with an invoice for a call-out charge. SGS maintained it was a call-out visit and that their engineer had identified the issues with the boiler and quoted a repair accordingly. This was completely false, sine we told him what the Ideal boiler specialist had advised needed to be done. I told SGS to check with the engineer or the original telephone call, which they did and, "on this occasion, as a gesture of good will" they decided to withdraw the invoice but stressed that any future call-outs would be charged as £75+vat so £90.00. Although it was not a call-out, SGS are in breach of consumer protection laws by not declaring a call-out charge or the amount before they visit or even mention it on their website.

Brilliant, professional job
The workmen, Ben and Dan, arrived on time. After introducing themselves they prepared the site laying dustsheets and protecting the carpet. All the works were explained and were taken in a professional manner. They cleaned up after the works. I would recommend them, really professional with an eye for detail. Really great job.

Excellent and very nice to deal with. We have enjoyed a faultless service by this company for approximately 20 years annual servicing of our 'old' original boiler and battery with several emergency call-outs during the winter 2016-17 and new replacement with us this year. We are grateful indeed.

Ben Docking and Dan Joseph from SGS installed a completely new central heating system. I was so impressed with the way they handled a pretty complex job in my 1911 three storey terraced cottage. They were polite and easy to have around and have done a brilliant job. So pleased.

Labour of love.
The house is old and listed so really tough job. Ben Docking and Daniel Joseph went more than the extra mile! Everything brought unseen problems, they sorted them and using skill (and some creativity) made sure the problems were solved. They worked very hard in difficult conditions to get the job done so we could move back into our home. Thank you!
