The SQ1 team were outstanding and provided a much appreciated stress free experience from start to finish. The install lads were a great bunch too and left our property spotless. We have no reservations in recommending SQ1 installations.

We have nothing but praise for Max, Oli and the team at Square1. From the moment Max came to talk to us to the time that Oli commissioned our battery and gateway, it’s been a pleasure being their client. We highly recommend them. And if you want the proof, just ask Max or Oli if you can speak to us directly we will be happy to endorse them.

Great company to deal with, very professional and helpful from the start. The fitters, electricians and all members of the team were very polite and did a great job. Very happy with our system and would happily recommend Square1 installations. We’ve now had our system for just over 2 years and it’s working great, having generated over 27 MW so far. It covers all our electric needs so we have no electric bills with the system easily covering our energy usage plus earning around £200-£300 extra per year.

From start to finish, my experience with this company, and their people had been impeccable, 100%, faultless. Max did the initial pitch, design and pricing, and actually advised us to go slightly smaller (and cheaper), than our initial idea; his wisdom has been proved correct over last 12 months. The installers lead by Ollie were tidy, cheerful, helpful - just brilliant. 12 months after installation, my electricity bill is probably a third of what it was before install, 4MW generated. A big thank you to Max, Ollie and team, you are brilliant.

Very, very impressed with this company. They explained everything before the installation, checked in the day before they were due to start and what a team of workers. They were such a lovely group of roofers and electricians who worked fast, were neat and tidy and so friendly. Now we are all connected to the grid, the support is ongoing to make sure we get the best out of the solar panels and batteries. We would definitely recommend them. Thank you to the whole team.

We'd been tempted to get solar for a while but never quite got to arranging it because there always seemed to be something we weren't keen on, like one company giving the quote and then getting another company to do the installation, or being charged a fee just for a quote. After seeing the good reviews for Square1, we contacted them and they were just a pleasure to deal with from that moment. Max was very friendly and helpful during the (free) quote and happily answered many questions afterwards. When we went ahead the lads that did the panels and battery installation were great, friendly and professional, the scaffolders were a pleasure too. And when the panels and battery were in, Oliver set it all up and was happy to explain how to use it and gave some great after-sales care, which was much appreciated. Everything was done very quickly and efficiently and we were happy to trust our house and roof to these people who clearly know what they're doing! A few weeks after installation everything is working well and, because it was fitted in early May, we haven't used any electricity from the grid since installation. Happy days! If we did decide to expand the system we'd be only too pleased to go back to Square1 to get it done. Thoroughly recommended.

Very pleased with my experience with Square 1. The initial site visit and quote was comprehensive and the advice given helped steer my decision. I thought the installation would be tricky on a brick and flint frontage but the team have come a very neat job so much so that the wiring is hard to spot! Once installed commissioning was quick and easy and good advice given on how to maximise the benefits and how to set up an export agreement. Overalll very pleased and wouldnt hesitate to recommend the Square 1 team!

First impressions in any relationship are vital and right from the word go I could not have been more impressed with Square1. Despite the narrow window we had to work in, Square1 reassured all my concerns and delivered a very professional installation in just two days. I would like to thank Max, Oliver, Phil and all the crew for doing such a great job, all worked tirelessly and with great humour. I feel I have the best possible solution for my house and comfortable that even after the job is done, that I will still be looked after by Square1. With a business model and staff like yours, then you will continue to succeed.

This is the second solar installation that we have used Sq1 for (the first being ours and this one being my parents). At every step of the way they have been excellent to deal with, the standards on both installations have been exemplary and they are always available for any questions and queries. I would highly recommend.

Solar & Your Energy Costs

What could the next 25 years look like?

Solar isn't just about what you pay for electricity today. It's about how much energy you could generate yourself over the years ahead.

The right solar and battery system can reduce reliance on grid electricity and give you greater control over changing energy costs.

Think long term

You're not buying panels. You're changing where your energy comes from.

A well-designed solar PV system can generate electricity from your own roof or land for decades. Add battery storage, and more of that energy can be kept for the times when you actually need it.

01
Generate your own electricity

Use suitable roof or ground space to produce renewable electricity at your property.

02
Use more of what you generate

Battery storage can hold surplus solar energy for use later in the day or evening.

03
Reduce exposure to grid costs

Every unit generated and used on site is one you don't need to buy from the grid.

Your property is different

The useful number isn't an average. It's yours.

Roof orientation, available space, electricity consumption, battery capacity and when you use energy all affect the potential return. SQ1i can design and model a system around your actual property and energy use.

Estimate Your Solar Potential
