The company said it wants to meet growing demand for short-term finance to pay for energy-efficient refurbishments.

The new product will be available initially on residential properties across the Northwest.

It aims to reward experienced property investors and landlords for their efforts as they face pressure to meet the Government deadline of a minimum C Energy Performance Certificate (EPC) rating for rental stock by October 1, 2030.

The new product offers bridging loans of up to £600,000 to purchase a property or remortgage a current loan and complete a scope of work to improve energy efficiency over an 18-month term. Monthly rates start at 0.99% at 75% loan-to-value (LTV).

Once energy saving measures such as air source heat pumps, insulation or triple glazed windows are installed – lifting a property’s EPC rating to C or above – a lower bridging rate is unlocked for the borrower.

The rate for achieving an EPC C rating is 0.95%, 0.85% for a B rating and 0.80% for an A rating.

The Charles Street team aims to test demand for the new product in the Northwest ahead of it looking to roll out nationally.

Charles Street development relationship manager Penny Ridgway said: “Over half of homes in the Northwest are estimated to have an EPC of D or lower, which means that there is a lot of pent-up demand to upgrade housing stock for residential or rental use.

“We are delighted to launch this offer to Northwest broker and direct customers as we support them by providing the financial headroom they need to realise their property ambitions. It is always our ambition to act as a partner with our end customers to help maximise opportunities through property.”
