Why Swansea Homeowners Are Switching to Heat Pumps

Swansea’s position on the south Wales coast gives it a mild climate well suited to heat pump technology. The Gulf Stream influence means winter temperatures stay relatively moderate, allowing air source heat pumps to maintain strong efficiency throughout the year.

Many properties around the Gower and rural areas west of Swansea are off the gas grid, relying on oil or LPG for heating. These homes see the biggest savings when switching — typically 40% to 70% reduction in heating costs.

For properties with garden space, ground source heat pumps deliver even higher efficiency. Swansea’s geology is well suited to borehole drilling, and our in-house drilling team has extensive experience working in the local ground conditions.

Frequently Asked Questions

How much does a heat pump cost in Swansea?

Air source heat pump installations in Swansea typically cost £8,000 to £18,000, and ground source systems £18,000 to £45,000 before the grant. After the £7,500 BUS grant, you could pay as little as £500 for a smaller air source system. Contact us for a free, personalised quote.

Are heat pumps suitable for Gower and coastal properties?

Absolutely. Swansea’s coastal climate is mild year-round thanks to the Gulf Stream, which means both air source and ground source heat pumps operate at excellent efficiency. For coastal properties, we recommend corrosion-resistant units. Many Gower properties are off the gas grid, making heat pumps the most cost-effective alternative to oil and LPG — savings of 40–70% on heating bills are typical.

Can I keep my existing radiators with a heat pump?

In many cases, yes. Heat pumps work at lower flow temperatures than boilers, so we assess each radiator during our survey. Larger and modern radiators usually work fine. Some homes may need a few radiators upgraded for optimal comfort, but full replacement is rarely necessary.

What grants can Swansea homeowners claim?

The £7,500 Boiler Upgrade Scheme grant is available to all Swansea homeowners with no income test. Welsh Government schemes including Nest and Green Homes Wales may provide additional funding for eligible households. We advise on all options and handle the BUS application on your behalf.

How long does installation take?

Air source heat pump installation typically takes 2–3 days. Ground source systems require 3–5 days for internal works plus 1–3 days for borehole drilling. Our in-house drilling team operates from West Wales, so scheduling is efficient and we restore all garden areas after completion.

Can I combine the BUS grant with Welsh Government schemes?

Yes, in many cases the £7,500 BUS grant can be combined with Welsh Government programmes like the Nest Scheme. This can significantly reduce or even eliminate the upfront cost of a heat pump. Eligibility depends on household income and property type. We can advise on the best combination of funding for your situation during your free consultation.
