Air Source Heat Pumps in Cornwall and Devon: 2026 Installation Guide
Cornwall and Devon are among the UK's best markets for air source heat pumps. Here's the full 2026 installation guide.

GivEnergy and FoxESS are two of the most installed home battery storage brands in the UK. Both offer solid performance, competitive pricing and good warranties — but there are meaningful differences in their product architectures, software ecosystems and support networks that affect which is best for different homeowners.
GivEnergy is a UK-based brand that has quickly become one of the market leaders. Their flagship product is the GivEnergy All-in-One (AIO) — a combined hybrid inverter and battery unit available in 2.6, 5.2, 8.2 and 9.5kWh configurations. The AIO format keeps the system compact and simplifies installation.
Key specs: 3,000–4,000 cycle life, 10-year warranty, round-trip efficiency of approximately 93%, and a comprehensive smartphone app with live monitoring and automated charge/discharge scheduling. GivEnergy integrates well with Octopus Agile and other variable-rate tariffs, allowing the battery to charge from cheap overnight grid electricity and discharge during peak hours.
FoxESS is a Chinese brand with strong global distribution and a growing UK presence. Their H1 and H3 series hybrid inverters pair with the ECS range of stackable batteries (2.56kWh modules). The modular design allows homeowners to start with one module (2.56kWh) and expand in future.
Key specs: 6,000 cycle life (higher than GivEnergy), 10-year warranty, round-trip efficiency approximately 91–93%, good app interface with solid monitoring and tariff-based charge scheduling. FoxESS is generally priced slightly below GivEnergy for equivalent capacity.
Capacity: Both offer 9.5–10kWh units. FoxESS offers expandability. Price: FoxESS typically £200–£400 cheaper per comparable capacity. Cycle Life: FoxESS 6,000 vs GivEnergy 3,000–4,000. Software: GivEnergy slightly ahead for UK tariff integration. Support: GivEnergy has stronger UK-based customer support. Warranty: Both 10 years.
For most Midlands homeowners, either system will perform well. If you want the most flexibility and best long-term capacity retention, FoxESS's higher cycle rating is an advantage. If you prioritise software sophistication, UK-based support and seamless tariff integration, GivEnergy edges ahead. We install both and can advise based on your specific system and energy usage profile.
