About Our Services

Heat pumps for Cardigan's off-grid homes

Large parts of south Ceredigion and north Pembrokeshire have no mains gas, so many homes around Cardigan, Aberporth and the Teifi valley still heat with oil or LPG. Renewable Heating Wales designs and installs air source heat pumps, solar PV, battery storage and underfloor heating for exactly these properties, from coastal bungalows to farmhouses and converted barns.

We are MCS-accredited and an Octopus Energy Trusted Partner, and we already work in Aberporth and the surrounding coast. We handle the Boiler Upgrade Scheme application from start to finish, and plan every system for the exposure and older construction that are common in this part of Wales.

What We Offer

Our Services in Cardigan

Most homes we visit around Cardigan are moving off oil or LPG, so we start with an air source heat pump designed around the building, then look at solar PV and battery storage to cut the electricity you buy. Underfloor heating and MVHR suit renovations and barn conversions.

Common Questions

Heat pump FAQs for Cardigan homeowners

Can Cardigan homeowners get the £9,000 heat pump grant?
Many can. The Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump, and £9,000 where the home is heated by oil or LPG and has no mains gas connection. Because so much of the area around Cardigan is off the gas grid, a high share of local homes meet both conditions. The £9,000 is confirmed until 31 March 2027. You also need to own the property and have a valid EPC with no outstanding loft or cavity wall insulation recommendations.
Is a heat pump cheaper to run than oil or LPG?
It depends on what you pay for fuel. At the October 2026 price cap, a well-designed heat pump costs about 7.5p per kWh of heat. That beats an older oil boiler once heating oil costs more than about 65p a litre, and beats LPG above about 48p a litre. On a dedicated heat pump tariff the break-even point falls further. Check your last delivery invoice, and we will model your actual running costs during the survey.
Will salt air on the coast damage a heat pump?
Not if it is specified and sited properly. Homes near Aberporth, Tresaith and the Teifi estuary are exposed to salt-laden air, which can corrode standard outdoor units over time. We choose units with suitable corrosion protection, position them away from the worst of the onshore wind and spray where we can, and set a servicing schedule that keeps the warranty valid.
Do I need planning permission for a heat pump near Cardigan?
In most cases no. Welsh permitted development rights were widened on 1 June 2026: a detached house can have up to two air source heat pumps and other homes one, provided the outdoor unit is no larger than 1.5 cubic metres. Extra restrictions can apply to listed buildings, conservation areas and National Park land, which covers parts of the nearby Pembrokeshire coast. We check the position for your property and deal with the council where an application is needed.
Will a heat pump work in an old stone farmhouse?
Yes, with the right design. Stone and solid-walled houses lose more heat than modern builds, so we size the system from a room-by-room heat loss calculation and often recommend larger radiators or underfloor heating so it can run at low, efficient temperatures. Where the building needs better insulation first, we will tell you, and you may be able to get that funded through ECO4 or Warm Homes Nest.
What happens to my oil tank when I switch?
Once the heat pump is running, the tank needs emptying and then either removing or safely decommissioning. Try to time your last delivery so you are not left with a full tank, and mention it at the survey so it is planned into the job. We can talk you through the options for your property.
