Overview
Why battery storage?
A home battery stores electricity to use later — solar power from the afternoon for the evening, or cheaper overnight electricity for the day.
We install Tesla and GivEnergy batteries, with or without solar panels, sized to how and when you use electricity.

Planning, regulations and timings
Siting
Batteries need a suitable location, usually a garage, utility room or outside wall, with space for safe access. We check at survey.
Grid connection
Your installer notifies the local Distribution Network Operator (DNO), and some systems need approval first.
0% VAT
Solar panels, batteries and heat pumps installed in homes in Great Britain are zero-rated for VAT until 31 March 2027.
Annual servicing
Every installation can go on an annual service plan, so it keeps running efficiently and stays within any manufacturer servicing conditions. Plans and prices are confirmed on request.
