Storage and electric heater replacement in Porthmadog
Old storage heaters in Porthmadog homes are removed and recycled as part of the replacement. North Wales has mild, damp weather for much of the year, so efficient heating and dehumidifying are big benefits.
Flats and bungalows in Porthmadog that have never had gas are the usual candidates for replacing storage heaters. Porthmadog sits around 21 miles from Bangor, Gwynedd, inside our Gwynedd area. Postcode districts we cover here include LL49.

Prices are shown before any Boiler Upgrade Scheme grant. The £2,500 air-to-air grant applies only to eligible homes in England and Wales, using an MCS-certified heat pump installed by an MCS-certified installer, who applies for the grant and deducts it from the price. We confirm eligibility, and which installer applies, before you commit.
Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
In Wales, outdoor units of up to 1.5 m³ that meet MCS 020a noise limits are usually permitted development on houses; listed buildings need consent, and in conservation areas a unit cannot go on a wall or roof facing a road.
If your home in Porthmadog is replacing fossil fuel or electric heating, and no gas, oil or LPG boiler stays in use, an MCS-certified air-to-air heat pump may qualify for the £2,500 Boiler Upgrade Scheme grant, which the MCS-certified installer claims and deducts from the price.
