Common Questions

Heat Pump & Solar FAQs for Cardiff Homeowners

What does an air source heat pump cost in Cardiff?
Air source heat pump installations in Cardiff typically range from £8,000 to £15,000 before grants, depending on property size and system specification. The Boiler Upgrade Scheme can reduce this by up to £9,000. We offer free, no-obligation surveys for Cardiff homeowners to provide an accurate, personalised quote for your property.
Am I eligible for a heat pump grant in Cardiff?
Most Cardiff homeowners replacing a gas or oil boiler with an air source heat pump qualify for the Boiler Upgrade Scheme (up to £9,000). Some households may also be eligible for ECO4 funding. We carry out a free eligibility assessment and manage the entire application process as your MCS-accredited installer.
Is it worth installing solar panels in Cardiff?
Yes. Cardiff benefits from sufficient solar irradiance to make solar PV a worthwhile investment. A well-designed system can reduce electricity bills by 40-60% and pair excellently with a heat pump to lower running costs further. Battery storage lets you maximise self-consumption of the energy you generate.
How disruptive is a heat pump installation in Cardiff?
A standard air source heat pump installation in a Cardiff home takes 2-4 days. Our team works cleanly and efficiently, keeping disruption to a minimum. We coordinate any additional work such as radiator upgrades or pipework modifications in advance, so you know exactly what to expect from day one.
Do Cardiff properties need planning permission for heat pumps?
Most air source heat pumps in Cardiff qualify as permitted development under Welsh planning rules, so no formal planning permission is required. Restrictions may apply for listed buildings, conservation areas, or noise-sensitive locations. Our team assesses your property and handles any planning queries with Cardiff Council before work begins.
Can I combine a heat pump with solar panels in Cardiff?
Absolutely — and it's one of the most effective ways to reduce energy costs in a Cardiff home. Solar panels generate free electricity to power your heat pump during the day, and with battery storage, you can store surplus energy for evenings. We design integrated systems that maximise the synergy between solar PV and heat pumps.
