Solar installation
Customer Service
We had solar panels and battery fitted in October last year, sws installed them, the guys that fitted the panels and battery were great, turned up on time and were finished in about 4 hours, everything neat and tidy, cables routed neatly in roof space despite being a bit of a squeeze for the poor electrician.Fitted maximum number of panels on two roofs. All working great. The scaffolders managed to break a few tiles, mentioned this to Nic , he got straight onto it. Within a couple of days sent roofer round to put things right. Great service, didn't have to wait months for the installation. Not the cheapest quote but all the gear is top quality. You get what you pay for. Definitely recommend.

Peace of mind guaranteed by their thoroughness
Customer Service
Investing life savings in Solar panels and batteries is never going to be an impulsive decision, brilliant efforts from all involved made it easy. Nic Goodwin's very thorough survey (including the loft!), ever cheerful and polite installers and office staff who followed up every stage to ensure all had gone to plan. After sales support is great. One month since installation we enjoy 5-10 kWhr and top up the batteries at off-peak rate saving us around £15 weekly in November! Recent talk of power cuts makes the Emergency Power Supply option well worthwhile. The system has already made our lives better and SWS deserve their success. Unreservedly recommended

Professional outfit
Customer Service
The whole project was a pleasant experience, from the visit, by an engineer not a salesman, to generate a quote through to handing over the working system. I also had to wait for my batteries, but that was out of their control. The panel installation was completed in a day by very experienced fitters. It came in under budget as they found they couldn't fit the quoted 9 panels.

Solar and battery installation; an excellent job.
Customer Service
A great experience from start to finish. The sales process was professional and informative, with no pressure. Installation was quick and efficient. There was a short term battery supply problem, but SWS were quick to provide a temporary solution, followed by the finished installation soon afterwards. I have no hesitation in recommending SWS for this type of installation.

Solar panels and batteries
Customer Service
Great service from initial enquiry to completion. We had to wait for a couple of weeks for the batteries due to a logistical problem but we were kept informed and updated by the SWS team, who were very helpful at all stages of the job. Thanks once again.

Solar PV with battery storage fitted without any fuss
Customer Service
We had a solar system with battery storage fitted by SWS and they come highly recommended. The communication was clear and their initial assessment / survey was not in any way pushy. The installation was very efficient, completed between 10am and 3pm, a tidy job by a team who clearly knew what they were doing. The system itself comes with a very useful app that allows you to see what's going on with generation, battery storage, consumption and import from/export to the grid. The only negative was that no one told us that the batteries wouldn't be available at the time of the installation, we didn't know until the installers arrived on the day. We then had to wait a month before the batteries were available, however we were given 6kWh of storage rather than 4.8kWh as was originally quoted, so that's certainly not something that means SWS deserve anything less than a 5 star review.

Solar Panels
Customer Service
Overall the service was very efficient, there was a delay of over 2 weeks to get my battery fitted due to supply chain issues but the communication and customer service was generally good

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.
