I contacted Green Team One 2 months ago after a failed Government Solar Grant Application. I decided to go it alone in this minefield of an industry. I found them through a friend’s recommendation. Green Team One came over for a recce. I got a very good quote. They continued to answer my tough questions regarding the horror stories I’d heard about bogus companies, equipment and installations. They installed the system and supported me through the whole process. They were quick, efficient and professional. They are continuing to support me all the way to my new Octopus Energy solar tariff choices. Rarely have I felt so comfortable and supported by a company but Green Team One are true professionals with a team of experience and enthusiastic Engineers, technologists, roofers, contract scaffolders and admin. They are superb to deal with. They get 5 stars from me without doubt!

We decided to invest in solar panels, battery storage, EV charger and an Air Source Heat Pump (ASHP), and approached a number of local companies for quotes. From the start of this process, Green Team One were very professional, with Rob spending a couple of hours at our home to go through our options and what our likely rate of return could be. As Green Team One were the only company out of the initial group we contacted that could also supply and install the ASHP in-house, we also had a visit from Bryan to carry out the heat loss survey. Again, this was very detailed – he listened to our expectations and then explained what our options were. Once we had received all the quotes, we decided to go with Green Team One – although they were not the cheapest option, we were very impressed with the level of detail provided and that they would be able to handle the entire installation themselves. A start date was agreed very quickly and clear communication was given as to what we would need to do before the work commenced. The work was split into two phases – with the solar panels, battery, EV charger and ASHP installation being phase 1 while phase 2 consisted of removing the old gas central heating system and replacing it with the new ASHP. Phase 1 was completed in a day and phase 2 in three days. We were very impressed with both the quality and the speed of the work. The team were very knowledgeable and answered any questions we had during the process. We were also given enough information at the end of each phase to allow us to use the new systems, with a more in-depth handover session set up for a couple of days later, to allow the system to bed in. The handover session was also very detailed – with demonstrations on how to set up and monitor the various apps and accounts needed to run and monitor the new devices, checks to ensure that everything was working as intended and time allowed to answer any questions we had. We have been very impressed with how Green Team One delivered on the whole project and turned what could have been a very stressful process into a very smooth experience. We would not hesitate to recommend them to anyone else that was looking to install a similar set-up.

There may not be huge demand for solar projects (or sunlight!) in January, but the speed and efficiency of installation of panels and battery in our town in north Wiltshire took our breath away. All the people who came to the house - three visits from individuals to advise and assess, and a team who completed the work in a morning - were friendly, on time, and professional. The firm is big enough to know its business, and local enough to be available if needed. Not the cheapest quote, but the level of service we have received already justifies their charge, and we feel confident that they will continue to support us.

After approaching a number of companies for a quote for the install of a solar + battery system Green Team One were far and away the best. From a fantastic initial quote with Rob - who came on a Saturday and spent close to 2 hours running through as much detail as I wanted, to the entire installation process I really can’t fault them. The install looks absolutely fantastic, works brilliantly and was installed to an incredibly high standard, taking my desires for placement of items into account - especially valuable to me as we have a cable run from the house to a detached garage. I would thoroughly recommend anyone looking for a solar system to get in touch with GTO!

Green Team One installed a solar system and battery at our property in Cheltenham. They were helpful, communicative and professional from first quote to the follow-up meeting to check we were happy with the work. There was no hard sell, they just gave us the information we asked for, answered all follow up questions and left us to consider the quote in our own time. The scaffolding went up when they said, and the roofers and electricians arrived at around 830am on install day and were finished by around 230pm. Very pleased with both the system they fitted and their professionalism.

We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
