Bluestone National Park Resort in Pembrokeshire has achieved a first in the UK holiday park sector by becoming completely fossil fuel-free across all its purchased energy sources.
The five-star resort began its transition at the start of the year and completed the move to renewable energy in September 2025.
The resort’s sustainability strategy includes an on-site solar park—the largest of its kind in UK hospitality—which now generates about one-third of Bluestone’s annual electricity needs.
Since April 2025, Bluestone has sourced its remaining electricity through a 12-month renewable energy contract with Ecotricity.
A small non-half-hourly supply covers the Black Pool Mill Heritage Restaurant, ensuring that every part of the resort’s operation is powered by renewables.
Bluestone has also replaced traditional fuels across its operations. The resort’s vehicle fleet is now entirely electric, while tractors run on hydrotreated vegetable oil (HVO).
All food and beverage outlets cook with BioLPG, a renewable gas produced from food waste, instead of mains gas. Backup boilers that once ran on kerosene have also been converted to HVO.
Marten Lewis, director of sustainability at Bluestone, said: “We purchase a huge amount of energy across the resort and have now completed the final stages of taking all our energy away from fossil fuels into certified renewables.”
He added that the Blue Lagoon water park, one of the first in the world to use local renewable biomass for heating, has long embodied the resort’s approach to sustainable energy.
“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.”
Lewis noted that Bluestone’s sustainability efforts extend beyond its direct operations. “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,” he said.
“Across the resort, people strimming hedges and cutting trees not employed directly by Bluestone have also decarbonized their fuels, switching to electric strimmers and hydrotreated vegetable oil, or HVO fuels, to power their mowers.”
The milestone marks the culmination of a long-term vision by Bluestone’s founder, William McNamara, who in 2004 outlined a regenerative tourism plan in the company’s “Green Book,” focusing on community support and biodiversity.
In July 2025, Bluestone was ranked the third-best holiday park in the UK in a Which? survey of 1,700 holidaymakers—placing above Center Parcs and Haven—and remains the only holiday park to receive a King’s Award in Sustainable Development.
For outdoor hospitality operators, Bluestone’s transition demonstrates how large-scale resorts can feasibly decarbonize energy systems through phased investments in renewable technologies and supplier partnerships.
It also highlights the growing importance of sustainability credentials in consumer choice and brand reputation within the competitive UK holiday park market.
