Bluestone National Park Resort in Pembrokeshire has become the first holiday park in the UK to be completely fossil fuel free in all its purchased energy.

The five star holiday resort near Narberth has now completed the final stages of taking all of its energy away from fossil fuels into certified renewables.

Bluestone’s on-site solar park is the largest of its kind in UK hospitality, generating a third of the resort’s annual electricity needs. The resort has a renewable energy deal with Ecotricity, Britain’s greenest energy company; Bluestone’s small vehicle fleet is now entirely electric; its tractors run on hydrotreated vegetable oil instead of diesel; and cooking at all food and beverage outlets is carried out using BioLPG which is made from food waste, instead of mains gas.

Marten Lewis, Director of Sustainability at Bluestone, said: “Our Blue Lagoon… uses waste products from local sawmills and other waste timber products to heat the water, and solar gain thanks to the building’s windows which act like a big greenhouse keeping it warm. In 2025 we’ve transitioned all remaining parts, like back-up boilers for the Blue Lagoon water park, so that Bluestone is now a resort entirely run on purchased fuel that is fossil fuel free.

“As part of showcasing a way forward for the responsible operation of holiday resorts, we have even taken our main contractors with us on the journey. Across the resort, people strimming hedges and cutting trees not employed directly by Bluestone have also decarbonised their fuels switching to electric strimmers and hydrotreated vegetable oil, or HVO fuels, to power their mowers.”

It’s a significant milestone for Bluestone’s founder, William McNamara, who in 2004 outlined a regenerative tourism vision in his ‘Green Book’.

Bluestone is the only holiday park to be recognised with a King’s Award in Sustainable Development. Find out more at bluestonewales.com .
