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.
