UNITED KINGDOM / AGILITYPR.NEWS / February 03, 2026 / Renewable energy company Ulex Energy is urging homeowners across South Wales to act quickly as funding for the Green Homes Wales scheme approaches capacity for the 2025/26 financial year - with the possibility that new loan offers may not reopen until after April 2026.

Delivered by the Development Bank of Wales, Green Homes Wales provides access to interest-free loans and expert support to help homeowners invest in energy efficiency measures such as solar PV, battery storage, insulation and low-carbon heating. However, demand for the scheme has increased sharply - and the programme is now nearing its funding limit for the current cycle.

Ulex Energy, a Swansea-based specialist in bespoke solar and battery systems, says that households considering renewable upgrades - but relying on grant or loan support to make projects viable - need to act fast.

“The Green Homes Wales scheme has played an important role in helping people move forward with solar and other improvements,” said Ian Mach, Founder of Ulex Energy. “What we’re seeing now is a real surge in interest, and that’s pushing the scheme close to capacity. Homeowners who leave it too late may find that funding simply isn’t available until well into the next financial year.

Under the scheme, eligible homeowners can access interest-free finance alongside fully funded retrofit advice, helping them spread the cost of improvements while reducing energy bills and carbon emissions. With wholesale energy prices remaining unpredictable, many households are turning to solar and battery storage to gain greater control over long-term energy costs.

Mach believes the potential pause in funding could leave some homeowners in limbo if they do not start the process soon. “These projects don’t happen overnight,” he said. “There’s an assessment stage, system design, installer quotes and approvals to work through. Funding is not guaranteed until an offer is formally approved, and availability depends on the scheme’s remaining budget.”

While alternative finance options exist, the interest-free nature of Green Homes Wales makes it particularly attractive for households looking to maximise return on investment without increasing monthly outgoings.

Ulex Energy is encouraging homeowners to seek advice early, even if they are still weighing up their options. “Starting a conversation now keeps doors open,” Mach added. “Even if someone ultimately decides not to proceed, understanding their eligibility and timeline puts them in a far stronger position than waiting until funding has already closed.”

Ulex Energy continues to support customers seeking to switch to renewable energy, from early design discussions through to installation - helping homeowners make informed decisions about solar and battery storage.
