The lender’s new mortgage range has a £250 cashback for those buying the most energy efficient homes and will be available through mortgage intermediaries, plus Halifax phone and branch services.

From Monday, homebuyers and movers purchasing a property with an Energy Performance Certificate (EPC) or Predicted Energy Assessment (PEA) rating of A or B can take advantage of the new green mortgage cashback offer if they’re borrowing below 85% loan-to-value (LTV).

The offer is available on selected Halifax mortgage products and is applicable for first-time buyers, home mover, shared-ownership and new build mortgages for the purchase of a main residence only.

The EPC rating of the property will be requested as part of the mortgage application, with mortgage advisers required to verify the appropriate certification.

If the EPC rating is A or B, the cashback reward will be applied automatically.

Ian Wilson, head of Halifax Intermediaries, said “Our new green mortgage cashback offer continues our work to help make Britain’s homes more energy efficient.

“This addition to our product range demonstrates another way that we are working towards our Group climate ambitions of halving our financed emissions by 2030.”
