UK green mortgages for energy-efficient homes

What are Green Mortgages?

Green mortgages in the UK are offered by banks and financial institutions to homeowners who meet pre-set environmental standards. Typically, lenders provide you with lower interest rates and cashback if your home meets the minimum energy-efficiency requirements in the Energy Performance Certificate EPC.

What is the Role of EPC in Green Mortgage Lending?

A green mortgage helps homeowners to cut energy costs by improving the EPC rating and resale value of the property. The EPC plays a crucial role in mortgage lending because it assesses the level of energy efficiency of a home.

An assessed home can be rated from A to G, with A being the most efficient and G the least.
The lenders use EPC ratings in affordability checks because properties with a high Energy-Efficient rating are considered less risky to invest in due to lower bills and better future value.
The UK government has set a goal of Net Zero Carbon emissions by 2050. New homes typically have an A or B rating, while older ones fall into a lower ranking due to their less eco-friendly design and systems.

Types of Green Home Loans

The “green” word in these mortgages aims to finance the home’s energy-efficient rating. UK lenders offer green finances in three ways:

Reduction Rates are provided to those homeowners who own a high energy efficiency rating. The lenders usually offer a cashback or lower the standard mortgage rates.
Capital Release options are used to pay for eco-friendly improvements through discounted mortgage rates or fixed cashbacks on existing rates.
Additional Borrowing on mortgage deals is available for home-energy efficiency improvements, such as replacing the gas boilers with an air source heat pump or improving insulation.

How does Green Mortgage Work?

Green Mortgage works by linking loan terms with your property’s energy efficiency. Like traditional mortgaging, the borrowers make monthly payments and pay the interest on the amount they take for 2 to 5 years. The general interest rate varies from 4.13% as the lowest to 5.46% as the highest.

Lenders take EPC ratings into account and their impact on energy expenses. Homeowners with higher-efficiency homes will be able to borrow more as they spend less on energy efficiency. If homeowners spend less on energy bills, they are less likely to struggle to repay their interest each month.
