Green Mortgages

An energy efficient home could save your customers money

For residential and buy to let property purchases and remortgages with an energy performance rating of A or B

What is a Green Mortgage?

According to UK Government National Statistics, residential properties make up 15% of the UK total climate emissions. At NatWest, we want to help to lower this and reward customers who are trying to do the same.

Green Mortgages reward your customers for purchasing an energy efficient home by offering a reduced rate on a 2 year or 5 year fixed rate mortgage, and they could also get cashback which will be paid to their solicitor on the day they drawdown their mortgage.

The offer is only available on selected mortgages marked with ‘Green Mortgage - Cashback’ and can be changed or withdrawn at any point. Max LTV 85%.

If your customers buy a UK home with a valid Energy Performance Certificate (EPC) rating of A or B they could be eligible to select a Green Mortgage product. Early repayment charges may apply.
