Boiler & Heating Services in Barmouth
Barmouth is a well-loved Victorian seaside town on the Mawddach estuary, with a great mix of terraced properties around the harbour, hillside cottages overlooking the sea and rural homes spread across the surrounding villages. Many properties in the area rely on oil-fired boilers, older heating systems and traditional Aga or Rayburn cookers — and we've worked on all of them over our 20+ years serving the region.
We also work with holiday let owners and landlords across Barmouth, providing prompt CP12 Gas Safety Certificates, annual servicing and rapid response repairs when tenants or guests need help.
Every job is completed by a Gas Safe registered engineer with proper local knowledge and a straightforward, honest approach. As a Navien Accredited Installer, we can also offer manufacturer-backed warranties of up to 12 years on gas boilers and up to 10 years on oil boilers.
