Heat pump, solar PV and battery storage designed as one system and installed by the same Aventus Eco engineers, responsible for the whole job from survey to commissioning. Real heat loss calculations, no subcontractors.
“Excellent service before & after installation. We’ve had very attentive customer service from Sean, and are very happy with the outcome of the installation of solar panels & batteries. We are also grateful for his knowledge and input into adjusting our heat pump and currently our bills are massively reduced.”

Homeowners in Scotland can continue to claim £7,500 to £9,000 for a new heat pump. Our MCS-certified installs, designed by a Heat Geek Mastery trained engineer, qualify for the maximum support.
You’re not alone in feeling the pinch of high bills.
“I can’t believe how much I’m spending just to heat the house.”
“I want to go green, but I’ve heard heat pumps and solar don’t work in older homes.”
“I had a bad experience before. How can I trust another installer?”
Every week, we speak to homeowners who feel stuck. High energy costs, cold homes, and the fear of making a bad investment keep people from upgrading. The good news? There is a better way.
Scroll to run the survey on a Scottish stone home: what we fit, where it goes, and what it does for your bills.
A 1920s stone semi, the kind we survey every week. Solid walls, roof facing south-south-west.
One quiet unit outside heats every room and your hot water, sized from a room-by-room heat-loss survey. Radiators or underfloor heating, both work.
Your roof starts making its own electricity, with panels set out to this exact roof's pitch and shading.
Daytime sun is stored, then runs the house all evening from a bank in the garage.
All three designed together and fitted by one MCS accredited team led by a Heat Geek Mastery trained engineer.

Access up to £7,500 in grant funding, £9,000 if you are rural, and a £7,500 interest-free loan through Home Energy Scotland.
Systems engineered for Scottish homes, including stone cottages and tenements.
Pick up where Octopus, British Gas and Aira left off: we rescue and rebuild failed installs to a Heat Geek standard.
High-performance results from a system sized to your property.
Choosing the right installer is the single most important part of upgrading your home energy system. Aventus Eco isn’t a sales-first business. We’re technical experts who care about performance, support, and long-term value.
We don’t install systems that won’t work. If your home isn’t suitable, we’ll say so.

Heat pumps can typically cost around £2,000 to £6,000 after Home Energy Scotland funding. Solar PV: £9,000 to £16,000 with 0% VAT until March 2027.
Yes. We design every system based on the actual heat loss of the property, not guesswork. We have successfully designed heat pump systems for homes up to around 280 years old.
No, unless you want to keep it for cooking. If you remove your gas supply completely, you also remove the gas standing charge.
Not necessarily. We only recommend changing radiators where the existing ones are not large enough for the required output. On an average installation, we typically change around four radiators.
You get a 5-year workmanship guarantee, manufacturer warranties, and direct WhatsApp access to your installer.

We don’t disappear after install. In fact, we consider aftercare just as important as installation.
Here’s how we make sure you’re looked after long-term:
We build relationships, not just systems.
