How It Works
No maze. No mystery. Three steps.
- Within 24 hours
You talk. We listen.
A few quick questions to understand your home and your goals. Then we'll show you what's achievable and let the data do the talking.
- Around 2 weeks
We measure. You decide.
Your choice: a home visit, or a call with a satellite plan of your roof. Either way you get a written quote to think over. No pressure and no contract on the day.
- 4 to 6 weeks
We install. You're live.
MCS-certified local engineers fit your system, then stick around: a decade-long workmanship guarantee and aftercare that answers the phone.
Transparent Pricing
The Straight Answer on Cost
Most solar and battery systems cost between £8,000-£12,000, depending on your roof, your energy use and the battery you choose. Your exact price is confirmed in writing at a free survey, and the price we confirm is the price you pay.
10 solar panels
4.8 kW of solar power from premium Aiko or LONGi 480W panels. Bigger roof, more power.
Tap a panel to remove it, or tap an empty space to add one.
Add a battery
Solar powers your home in the day. A battery stores what you don't use, so you can use your own solar electricity in the evening too.
Battery size
About 5 kWh each.
How many?
1 battery, up to 3.
Stores spare daytime power for the evening. The exact size depends on the brand, so each one below shows what it actually fits.

The Valhalla Guarantee
Our Word, In Writing
No asterisks the size of icebergs. Three promises, plain English.
Your deposit is protected
Independent insurance covers it from the moment you pay it. Your deposit is never at risk. Pay your deposit by credit card if you like, so Section 75 protection applies. The final payment is only due once your system is installed and working.
Our workmanship is guaranteed for ten years
A decade of cover on the work itself, backed by insurance rather than a handshake. If anything needs putting right, we put it right.
Your first year's output is guaranteed
If your system generates less than its official MCS production estimate, you're covered in full, on the rare chance it's ever needed.
Small print: Your deposit and our 10-year workmanship guarantee are insured through the IWA. Manufacturer faults, your bill savings, and an obvious mistake in the written estimate itself are not covered. Full terms in your contract.
