Like many busy parents balancing full-time work and rising costs, Adam Swallow was looking for ways to protect his family budget. When he moved back to Bedford with his wife and two young sons, he decided to take control of his utility bills by putting his house to work. Over time, Adam Swallow has converted his five-bedroom house in Bedford into a super-efficient home energy ecosystem – slashing his bills, building resilience, and turning him into the go-to solar expert among his group of friends.

“I'm in the most expensive time of my life, “says Adam. “I'm working full-time, my wife works full-time and I've got two kids. Life is not cheap. If there are longer-term investments I can make to reduce how much I pay in bills, that seems like a really sensible and worthwhile investment.”

The manifold benefits of that investment still seem to surprise Adam. “I'm literally looking at my app now,” he says, slightly disbelievingly. “And I'm £450 in credit. I pay Octopus £150 a month via direct debit, and I reckon before we get into the colder months, I'm going to have around £700 that will see me right through the winter.”

After 20 years of living in Manchester, he moved back down to Bedford with his wife and two sons. Using equity set aside from the house move, he set about putting together a super-efficient system to run the household effectively. In his day job as head of security and revenue protection at Docklands Light Railway, he understands the value of reliable, optimised systems – so it was no surprise that he brought that mindset to his home installation.

Combining solar, batteries, and heat pumps

He was familiar with solar panels, having had them on a previous property, but the battery – a 10kWh SolarEdge setup – was new to him. “It's been absolutely brilliant. I compare my bills rather snobbishly with my friends as I bore them about solar stuff over a pint. The difference made by the battery and the solar panels working in concert is quite dramatic.”

And the newest addition – an air-source heat pump – has performed exactly as hoped. “It’s effectively like a new boiler, but it doesn't run off gas; it's all electric. It’s like a mega-efficient fridge in reverse. During the winter – and we had a cold winter this year – the heat pump just stays on like a fridge does, keeping the house at a really nice, cosy 20 degrees.”

To keep costs down, he is on the Intelligent Octopus Go tariff, which is designed with EV drivers in mind. “When you get an electric car, which I did a couple of years after getting the solar panels, you unlock tariffs that allow you to charge very cheaply overnight. I can get 10 kilowatt-hours of stored energy for about 75p.”

Fast payback and no gas standing charges

An extensive ecosystem like his involves some initial expenditure, but it has been worth it and then some. “We installed the solar panels and batteries in 2022, and then the heat pump in 2025. In just four years, I have completely paid back my initial investment in the solar panels and batteries.”

Part of the reason the system paid for itself so quickly was the energy price hikes precipitated by the war in Ukraine, but now his system is in place, he feels insulated from future market shocks.

He also took the opportunity to streamline his utility setup completely: “I even got rid of my gas hob in the kitchen when I got the heat pump installed, so they took away the gas meter and I don't pay a standing charge now. On that alone, I’m saving about £150 a year.”

Becoming the neighborhood solar expert

Off the back of his success, he’s become the go-to solar authority among his friends, evangelising for the technology over a pint in the pub or in WhatsApp groups.

“I would absolutely advocate it,” Adam says. “Get the solar panels and get the heat pump, and you can create a really efficient little microcosm.”

And he’s always keen to point out how straightforward the transition was: “The installation process for the heat pump was lovely. We had four guys who worked for about four days, and they were all polite, dead accommodating, and really patient. It was just a very positive experience.”
