55.35kWp system saving £17,626 a year for Brooklands Health & Sports Club.
Project overview
We’ve installed a 55.35 kWp system for Brooklands Health and Sports Club. The installed system generates over 50,000 kWh of energy annually representing a return on investment for the client of just over three years! Based in Sale, Cheshire, Brooklands Health Club provides a premium health and wellness service. This includes constant operation of a gym, spa facility, swimming pool and club lounge. This large offering of services results in a larger energy demand for the club, with the addition of Solar PV, the club now self-generates over 15% of its demand directly.
The challenge
Like most leisure & sport operations, Brooklands Health & Sports Club faced a structural exposure to wholesale electricity prices — a cost line that doubled for many UK businesses between 2021 and 2023 and shows no sign of returning to pre-crisis levels. With significant daytime load and suitable roof space, on-site generation was the obvious lever, but the project needed to stand on its own commercial merits: predictable payback, manufacturer-backed warranties, and zero operational disruption during install.
The solution Alliant Energy designed
Following a structural roof survey and DNO capacity check, Alliant Energy specified a 55.35kWp array using 126 high-efficiency mono-PERC panels, paired with a SolarEdge hybrid inverter. The SolarEdge platform was chosen for its export-management capability and remote firmware updates, allowing the array to be tuned over its life without site visits. Surplus generation is exported to the grid under a Smart Export Guarantee tariff, providing a secondary revenue stream alongside the primary saving on imported electricity.
Install & commissioning
The full installation completed in 2 weeks, scheduled around the customer's operating hours to avoid downtime. Work was carried out by Alliant Energy's directly employed MCS-registered engineers — no subcontracted labour. The system was commissioned to G99 requirements, registered with the Microgeneration Certification Scheme, and handed over with monitoring access, electrical certification, and structural sign-off documents on the day of completion.
Financial outcome
In its first full year of operation the system is on track to save Brooklands Health & Sports Club approximately £17,626 on electricity costs, with a payback term of 3.5 Years and a projected total ROI of 714%. Over the 25-year warranted life of the panels, the cumulative saving is forecast at £331,418 — a figure that improves materially if grid prices continue their long-term upward trend, and that benefits from the UK's 100% full-expensing capital allowance for qualifying solar assets.
Environmental impact
The installation displaces roughly 11.1 Tonnes of CO₂ emissions every year compared with grid-sourced electricity. Over the system's 25-year design life that is the equivalent of removing more than Brooklands Health & Sports Club's entire annual Scope 2 footprint several times over — a material data point for ESG, B-Corp and net-zero reporting frameworks.
Why it matters for the leisure & sport sector
Leisure & Sport businesses typically run daytime electrical loads — refrigeration, machinery, IT, lighting, compressors — that overlap closely with solar generation. That overlap is what drives strong economics: every unit generated and consumed on-site replaces a unit that would otherwise be bought from the grid at full commercial rates. The Brooklands Health & Sports Club project demonstrates how the model scales for this kind of operation.

Project FAQ
How much does Brooklands Health & Sports Club save each year?
Brooklands Health & Sports Club saves approximately £17,626 per year on electricity, with projected lifetime savings of £331,418 over the system's 25-year guaranteed performance period. The payback term is 3.5 Years, delivering a total ROI of 714%.
Was the project funded or paid for upfront?
This project was paid for directly by the customer. Under the UK's full-expensing capital allowance, the entire cost can be deducted from corporation tax in year one — improving the effective payback meaningfully for profitable companies.
What's the environmental impact?
The system avoids around 11.1 Tonnes of CO₂ emissions every year compared with grid-sourced electricity. Over a 25-year design life that's a material contribution toward Scope 2 reduction and any ESG or net-zero reporting commitments the business holds.
Could a similar system work for my business?
Probably — the same hardware platform (panels, hybrid inverter, optional battery) scales from roughly 10kW up to 1MW+. The deciding factors are roof area, daytime electricity use, current unit rate, and grid-connection capacity.
