Air source heat pump installation
Customer Service
I was very happy with the installation of the air source heat pump, radiators and new pipes. They spend quite a lot of time answering all our questions and made sure there was as little disruption to my home as possible (not an easy task when you are installing new pipes for radiators everywhere). The workmen were friendly and courteous. And although there was some mess while they were working everything was cleaned up before they left. They also arranged for our old oil tank to be removed before the work started and helped relocate two light switches that were in the way.

Very efficient and effective service
Customer Service
Installing air source heat pump and new radiators. All work was carried out with minimum disruption and on time. There was good liaison between the company and ourselves right from the start, initial inspections were carried out and all works required and costed were completed to a high level with no last minute changes of any significance. The work was carried out quickly and efficiently, all work areas were left neat and tidy and all old radiators and old packaging were removed as arranged. Any minor problems were discussed and explained well and did not significantly effect the work. The system was set up for us and it’s operation explained precisely and clearly. There have been no problems with the operation of the system. Overall we have been very pleased with the whole procedure and cannot find fault with anything.

Second to none customer care
Customer Service
ASH pump and cylinder installed and 9 rads upgraded. Work was done within agreed schedule and budget. It quickly became apparent that the initial installation team lacked the necessary expertise to carry out the work competently. Several problems manifested themselves. However, SWS management very quickly addressed the problems. Their conduct was exemplary: they were extremely helpful, kept in constant communication and were not satisfied until the last issue had been fixed. I have since recommended the company to family, friends and neighbours.

Outstanding Company
Customer Service
My in-laws had solar panels installed in 2006 by a totally different company. They recently had a leak and contacted the company who advised they could not come out to the until March 2022. As this was not acceptable, I contacted SWS Northwest Ltd on 3rd Feb. The telephone was answered by a lovely lady called Lisa. I explained I was looking for someone to remove solar panels due to a leak. She kindly passed my details over to Shaun, one of the directors of the company. He telephoned me within 15 minutes of my initial contact. I explained what I wanted and that the other company could not come out until 2022 and he was horrified. He advised someone could come on Saturday 6th around 12ish. He phoned me at 12.15 to see if the lads had arrived and I advised no, he said they should be with us with in the next 10 - 5 minutes but if they had not arrived by 12.40 to call him. The lads turned up at 12.30. They asked why we were removing them and I explained again to them what had happed and the timeframe. They too were horrified. They took the solar panels off the roof, to reveal a horror scene. The previous company had completely damaged the roof. SWS moved tiles around to stop the leaks, after they drove around looking for somewhere that sold new tiles. My in-laws were speechless at how fast this company had been in resolving their issue. We are truly humbled and grateful for their help. They have gone above and beyond and provided an extremely excellent service.

Good quality, professional job.
Customer Service
Did a great job installing an air source heat pump at my house. Went over and beyond, to complete the job, despite delivery delays. Stayed an extra half-day (plus long hours on the other workdays) to finish. Very helpful, hard-working and pleasant to have to do the work.

Customer Service second to none
Customer Service
[I do not understand the tick box at the top: if I tick it and therefore claim that I haven't used this trader, how could I share an experience I haven't had? Am I missing something here?] SWS installed an ASH Pump (17kw), compatible cylinder and nine replacement, upgraded radiators. Communication between SWS and myself remained flawless throughout. The on-site technicians were quick, clean and efficient. They were ready to listen to and answer any queries I had and demonstrated a good level of knowledge in their responses. The work was carried out to the agreed schedule and budget, though certain teething problems were encountered. These, however, were remedied rapidly. The most outstanding aspect, apart from my satisfaction with the product itself, was the level of aftercare. The coordination between the main office and the installation technicians was superb and the experience has left me with a high level of confidence in SWS.

Air source heat pump fitted and working
Customer Service
We had researched this system a little and following the visit by the sales chap, we took a couple of days to make a decision. Within a 5 week period the system was fitted up and working. Iwan, the lead of the fitters team worked continually, non stop and jobs were finished as if it were wizardry. The only time he would stop was when you asked for an explanation of how a piece of equipment worked and he would give a complete explanation, fitting in the pieces a step at a time to provide an overall picture of what he was doing. A job well and quickly done by a team of competent, efficient and tidy workers.

Myself and my wife are both disabled and where left without any heating when our boiler broke down and was too old to be repaired. Mr Watson of SWS services heard of our difficulties, immediately came to our aid and fitted a new top of the range boiler for us within 24 hours. He couldn't do enough for us his work was first class and I wouldn't hesitate for one minute to use him again
