How one Plymouth home went fossil free and how you can do it too

When Andrew and his wife moved into their modern Plymouth home, they made a bold decision: remove gas from the picture entirely and build a smart, low‑carbon energy system that could keep them warm, cut their bills and reduce their environmental impact.

Since then, their mix of an air source heat pump, an expanded solar array and home batteries has kept their four‑bed detached house reliably cosy year‑round, while proving that, for households able to invest upfront, a greener, mostly self‑powered home is achievable.

Andrew’s now sharing what he learned along the way to help others understand what’s involved and what to consider before starting a similar journey.

1. Choose your installer carefully

Use independent review sites like Trustpilot to find firms with a strong track record in the relevant technology. If you want a whole-house solution (heat pump, solar, batteries), look for a contractor who understands how all the parts work together, not just one element.

2. Insulation and EPC ratings matter

A heat pump works best in a well-insulated home. With an EPC rating of 83 (B), Andrew’s house was already performing well, which helped the system deliver good comfort and efficiency.

3. Make sure the system is MSC certified

MCS certification gives assurance on quality and is often essential if you want to access Government incentives or future support schemes.

4. Data is your friend

Using apps, smart meters and even a simple home weather station can help you understand how your system is working and spot ways to fine-tune it if needed.

5. Think about your motivations

For Andrew, the main driver was climate action, not a quick financial return. This mindset can make decisions easier, especially when energy prices and tariffs are fluctuating.

Andrew’s experience shows that moving to a low‑carbon home energy system is possible with the right preparation and mindset.

His biggest takeaway? Do your homework, and perhaps most importantly, be clear on your motivations. If your goal is long‑term resilience and reducing your carbon footprint rather than chasing quick paybacks, the journey becomes far more straightforward.
