What we install

Fabric first, then renewables. One working system.

Insulation, solar, storage, heat, EV charging and boilers, work most firms split across seven different vans. Here it is designed together, installed by one in-house team, and handed over as a single system with one survey, one warranty file and one number to call.

01 · Insulate

Fabric insulation, keep the heat you already pay for

Fabric first, always: loft, cavity and solid-wall insulation that cuts heat loss before a single panel or pump goes in. It is the most cost-effective energy upgrade there is.

How it works

Scroll the journey, watch the house change.

Step 01

A short call

Ten minutes, no script. You tell us what you want and what the house is like; we tell you honestly whether it's worth a visit and whether grants apply.

Step 02

A proper survey, free

We measure heat loss, fabric and electrics room by room. The findings are yours to keep, whatever you decide to do next.

Step 03

One clear price

A single document in plain English, with any grant already deducted. The figure you see is the figure you pay. Nothing moves after you say yes.

Step 04

A clean install

Dates agreed up front, our own crew, your home left tidy each evening. We handle the grant and finance paperwork in the background.

Step 05

Handover, then us on the same number

We walk you through the system in person and hand over your certificates. When you call afterwards, it's the same people who did the work.

Our story

We built the company we wished our customers had called first.

Smart Energie started because too many homes were being sold systems that were never sized for them. Years on, we still measure every house before we quote it, and still turn down work that isn't right.

Jobs we have deliberately walked away from

A heat pump on a poorly insulated house. We fixed the fabric first, then it made sense.

An oversized system to win on a spec sheet. Right-sizing saved the customer money.

A rushed deadline we could not hit to standard. We will not cut corners to finish a job.

In their words

Customer satisfaction, measured from post-install surveys. We ask every customer, and we publish the rolling figure.

Across 1,879+ homes upgraded, from single boiler swaps to whole-house retrofits.

★★★★★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.

Emma C., Southampton

Semi-detached, 1930s

★★★★★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.

David R., Sheffield

Victorian terrace

★★★★★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.

Mark & Louise T., Nottingham

1970s detached

★★★★★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.

Sarah K., Bristol

★★★★★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.

James T., Leeds

★★★★★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.
