We fitted a Warmflow Agentis E21PRO, one of the most efficient external oil boilers on the market. With its A‑rated performance, 21kW output, and clean‑burn Blue Flame technology, it’s a brilliant upgrade for comfort and fuel savings.

Proud to keep our local villages warm and running smoothly.

• ERP A‑rated performance — ensuring lower running costs and improved environmental impact.

🏡 Perfect fit for a historic Wiltshire cottage
