Standing proudly in the Lake District for over 800 years, Muncaster Castle has witnessed countless innovations come and go—but its latest may be its most significant yet. Known as the UK's first ‘eco-castle’, the castle is heated by a ground source heat pump, proving that historic homes can embrace sustainability without compromising structural integrity of the castle. 

Ewan Frost-Pennington, Director of Operations at Muncaster Castle, said: "Muncaster is proud to be known as the UK's first eco castle! The heat pump has made a world of difference, keeping the castle warm and cosy without the usual heating headaches. Unlike traditional heating systems, the heat pump maintains a stable temperature around the clock without breaking the bank. This isn't just great for comfort—it's essential for preserving our priceless artefacts, books, paintings, and even the structural integrity of the castle itself. It's been such a game-changer for our historic homes I hope it reaches its potential with all UK homes!"

Ian Morrison, Director of Policy and Evidence at Historic England, added: "There's a common misconception that older buildings can't accommodate modern, sustainable heating solutions, but that's simply untrue. At Historic England, we actively support homeowners and custodians of historic properties seeking to reduce carbon emissions with technologies like heat pumps and solar panels. Done thoughtfully and carefully, these solutions can make homes more energy-efficient and protect our heritage by ensuring they remain viable places to live in the future."

Muncaster Castle most recently provided a stunning backdrop to the new ‘Pride & Prejudice’ campaign which was fronted by model and sustainability champion Daisy Lowe. The government campaign highlighted the benefits heat pumps can bring, such as creating a warm and cosy environment, while encouraging homeowners to take advantage of the UK government’s Boiler Upgrade Scheme.

As part of the campaign, new survey revealed that Brits are swapping scepticism for celebration as heat pumps become the latest home innovation to shed their ‘prejudice’ and gain ‘pride’.
