What our customers say
Our electricity bill has dropped by over 60% since going solar with Wattli. The install was quick and the team were brilliant. Wish we'd done it years ago.
Sarah M.
Chelmsford, Essex
From quote to install in under two weeks. The panels look great on our roof and the app shows exactly how much energy we're generating. Amazing value.
James & Claire T.
Colchester, Essex
Had the full package — panels and battery. We're barely using any grid electricity now. It's like having our own mini power station. Couldn't be happier.
David R.
Brentwood, Essex
The team were so professional and tidy. They explained everything clearly and the MCS certification means we're eligible for the Smart Export Guarantee. Really impressed.
