FAQs

Thermal stores & boilers questions

Do I need a thermal store with a heat pump?▾

Not always — but a buffer tank significantly improves heat pump performance by preventing short cycling. If you are integrating with a boiler or solar thermal, a thermal store is usually essential. Typical cost: £2,000–£4,500 installed.

Can I keep my gas boiler when I install a heat pump?▾

Yes — a hybrid system pairing your existing boiler with a new air source heat pump is very practical, especially for older properties. The heat pump handles most heating; the boiler provides backup on the coldest days. This approach also qualifies for the BUS grant.

What does an annual boiler service involve?▾

Our service includes visual inspection, safety device checks, component cleaning, gas pressure checks, heat exchanger inspection, combustion efficiency testing and a service record. We also carry out a Gas Safety Check as part of the service.

Do landlords need a Gas Safety certificate?▾

Yes — landlords are legally required to have all gas appliances inspected and certified annually by a Gas Safe registered engineer. We provide landlord Gas Safety certificates across South Wales.
