Use your own solar after dark.
Battery storage captures the electricity your solar panels generate during the day and releases it when you need it — evenings, mornings, overnight. Or charge from the grid at off-peak tariff rates and discharge during peak. Either way, you stop buying electricity at its most expensive.

of solar self-consumption with a battery
Store now. Use later.
A home battery captures the solar electricity your panels generate during the day — power you’d otherwise export to the grid for pennies — and holds it until you actually need it. Run your evening, your overnight heating, even your morning kettle on the sun you caught hours earlier. With a smart inverter, the battery decides moment-by-moment whether to charge, discharge or hold, so you get the most from every unit you generate. Add cheap-rate overnight tariffs and you can also store grid electricity when it’s cheapest and use it when it’s most expensive.

One accountable team, end to end.
Most retrofit projects fail because nobody owns them. We design, fund, install and warranty in-house — so you only ever deal with one team that’s accountable for the result.
End-to-end ownership
Design, funding, installation and aftercare under one roof. We’re MCS, TrustMark and PAS-certified to deliver every stage in-house — no subcontractor finger-pointing.
Funding handled for you
We’ve secured £12M+ for customers across HUG2, BUS, GBIS, ECO4 and SHDF. The application paperwork stays with us — not you.
Quality, not volume
1,154 lodged projects across the group, every one designed for long-term performance. We turn down work where the numbers don’t make sense for the homeowner.
Real people. Real homes.
Every project starts with a quote and ends with a homeowner who notices the difference. Here’s what they tell us.
“Bright Nest handled the entire project from the initial survey to the final commissioning of our solar PV and battery system. They kept us fully informed at every stage, and the system is performing exactly as predicted — we’re already seeing significant savings on our electricity bills. Professional from start to finish.”
