Home energy in Gwynedd
Well over a third of homes in Gwynedd aren’t connected to mains gas — one of the highest rates in Great Britain. Most rely on oil, LPG, electric storage heaters or solid fuel, which makes the area a priority for heat pump funding.
That’s about 30,142 of the 61,800 homes in Gwynedd — higher than the average for Wales.
