Replace your inverter
We replace inverters on systems other firms fitted. The price depends on the inverter you have,
the size of your array and your wiring, so it is set at your free roof design visit — we don’t
put a number on screen we might have to change.
Thinking about a battery too? A hybrid inverter lets you add one now or later — we’ll show you
both prices at the same visit.

When is someone usually home?
Solar works hardest when you use power as it’s made — this shapes your battery advice.
Any big electricity users?
These change which battery size suits your home.
Battery storage?
A battery stores daytime solar for the evening — you’ll see prices either way.

Package prices are based on one roof elevation with a single scaffold lift. Extra roof faces or additional scaffolding are quoted at survey. Your free roof design confirms the exact fixed price in writing.
Who actually does the install?
Our own MCS-certified team — not a subcontractor network. A company owner is on every install, which is exactly why we can promise what we quote.
How long does installation take?
Most solar-and-battery homes are done in 1–2 days, panels-only usually in a day. Scaffolding typically goes up a day or two before.
What happens after I request my free roof design?
We design your system from your roof and answers within 24 hours, then email it over with your exact fixed price — and call once to walk you through it. The price is valid for 30 days while you decide. No pressure, no drip-pricing.
I already have solar panels — can you help?
Yes. We add batteries to, and replace inverters on, systems other installers fitted.
Do I need planning permission?
Almost never — home solar is permitted development for most houses. Listed buildings and conservation areas need a check, which we do for you at design stage.
Done — your free roof design is on its way.
Your reference is . Your free roof design and fixed price will be with
you within 24 hours — and this price is held
