What customers say,the rolling figure,and the two-star ones too.

They told me to sort the loft insulation before we talked about a heat pump. That single sentence was why I hired them. No one else had suggested the cheaper job first.

Quote matched the invoice to the pound. The team were in and out in four days, left the kitchen cleaner than they found it, and the new boiler's knocked about £40 a month off our bills.

We had three surveys before theirs. Theirs was the only one that explained what wouldn't work in our house. That's how we knew.

I was nervous about the whole thing. We'd had a bad experience with another company who left us with a faulty boiler and stopped answering the phone the moment we mentioned it. Smart Energie were a different planet. The engineer talked me through everything before he started. The quote matched the final invoice to the penny. He cleaned up better than we do. Our bills dropped noticeably in the first month. And when we had a question about the controls six weeks later, the same engineer rang me back the same afternoon.

The solar and battery have been running for four months and we've barely touched the grid. What I really appreciated was how upfront they were before we signed anything. They told me our south-facing roof was good but not perfect, gave me a realistic generation forecast, and the system has hit it almost to the kilowatt-hour. That kind of honesty before the sale is rarer than it should be.

We have two small children and I was dreading three days of engineers in the house. They were brilliant. Polite. Quiet during nap times when I asked. Tidy at the end of every day. The heat pump is much quieter than I expected and the house is genuinely warmer, even the kids' bedrooms, which used to be freezing in winter. I'd recommend them without hesitation, to anyone.
