Why regional firms are winning the retrofit market — and a tour of who is serving where, region by region.
Choosing an installer
Before comparing battery brands it is worth working out what size solar battery you actually need. And churches bring their own rules — listed-fabric fixings and faculty jurisdiction — which is why parishes go to dedicated UK church solar specialists.
When you're ready for quotes, a good local installer usually beats a national call centre on price and aftercare — see, for example, solar installers in Hertfordshire, ElectriFusion Solutions in South Yorkshire, or AMP Pro Electrical. For EV-charger pairing, this Zappi vs Ohme vs Hypervolt comparison is a useful read. Running a business instead? See solar panels for UK factories and the commercial solar payback period. For batteries specifically, an installer's Sigenergy vs Tesla vs GivEnergy comparison is a useful real-world read.
