Sustainable Energy Engineering - Washington

I have no hesitation in recommending Sustainable Energy Ltd. From the start and initial enquiry, the team have been very helpful and responsive to our questions. We now have 12 solar panels and all the additional electrics, neatly installed. The job was quite hard, due to the nature of our property and age of the slates on the roof. The weather was also awful for a couple of days of the installation. However, the lads were always polite, cheerful and helpful to have around, despite the circumstances and just cracked on. Their instructions have been clear and they have organised the paperwork required as quickly as possible so we can gain the best from our panels. Excellent job! Thank you!

I did loads of research before choosing Sustainable to fit/install my solar panels and battery. I promise you it paid off, from the start to finish this family run company nailed it for me. My installation was mid Feb 2024. I'm not originally from around the NE, and I decided to go with a local company which also had great reviews. Choosing them was the best thing I did and I can't rate them highly enough. (Sorry I forgot to put this review on sooner) apart from the good reviews previously, there are 3 reasons why I choose them, 1- good price for a good job, 2- SUS was one of a few company's that install a switch over switch, so I could, say in the event of a power cut, switch over and use my batteries power to run my house. (As a short term solution) for info, you can use your batteries power in the event of a power cut, for example, unless a switch over switch has been install as you need to isolate you from the grid. 3- local family run business was also a factor for me.
Hope this review is helpful, as solar is worth having if you can afford it. I didn't take a loan but I still may have so go for it if you get chance. 5 Star review, thx for reading, Julian S. Hartlepool. Adding the review on 19/06/24.

Luke, Stephen and all the team at Sustainable Energy Engineering were a pleasure to work with. Their team were on time, worked solidly and did a fabulous job. I would highly recommend them for any solar installation.

We had been recommended Sustainable Energy Engineering by family who had one of their systems installed. The whole process with Steve, Luke and the rest of the company has been an extremely smooth one. They produced an extremely competitive quote in comparison to other local trusted installers and discussed with us some options we had, explaining the benefits of each. Steve came out to see us (on my request) and diligently talked me through our options which led us to making a decision to go with them. There was no pushy salesman talk, just sound advice.
We made a couple of changes to the system which required a G99 application to Northern Powergrid, the team had the paperwork off quickly which meant we could get the approval and make the install date we wanted!
On the day of the install, the scaffolders arrived and were very efficient at getting the scaff up. The lads from Sustainable Energy Engineering arrived about an hour later and set to getting the roof work and cable runs sorted. They had a few bits to finish the next day but by midday our panels were producing and the site was tidy. The system has been working really well so far (Fox ESS 8.29kwh battery and 5kw inverter with 12x435w JA panels).
We have also had great communication after the install. The handover pack was promptly sent following payment and the relevant documentation and notifications were present.
So all in all, great pre-sales, great after sales, great installation and great post-install care.

Thanks for all your hard effort guys!

Sustainable Energy Engineering installed my solar panels about 10 years ago. They quoted an extremely competitive price. Installation was quick, with no mess.The panels have more than paid for themselves since their installation. I recently had a letter from the company, with details of battery storage. Steve came round to talk to me about it and do the maths. He came to the conclusion that the possible financial gain over the anticipated 10 year battery life, would be negligible. He was completely honest and didn’t try to sell me something that I didn’t need. I highly recommend this company. First class service.

SEE installed 18 solar panels on my roof in 2011 doing a great job. I had them back this year to fit 6 more panels with battery storage. Totally hassle free from planning the job to installation. When an issue developed later on due to aging panels, not the installation, SEE responded on the day to deal with it. Great after sales service. I totally recommend Sustainable Energy Engineering.

Having dealt with the company in the past I was fully aware of their high standards and competent work. The latest installation fulfilled their usual ethics and it went ahead with no problems. Operation of the system was explained fully and the job completed in a single day. I am very satisfied with the installation.

Nothing but praise for Sustainable Energy Engineering! Recommended by some neighbours and we've been really happy with them. We wanted a quite complex solar panel system, with panels on the house (slate roof) and on a detached garage...and a battery. They designed the system to include optimisers where we get a bit of shading and. linked the whole lot together. The installation was very efficient - took 3 days (including one where it poured with rain almost all day, so they did all the inside work then) - the lads worked really hard and were a pleasure to deal with.
