Can Energy-Efficient Homes Really Get You a Better Mortgage Deal

Many homeowners are surprised to learn that yes - having an energy-efficient home can sometimes unlock better mortgage rates. But how does it actually work? And is it worth considering if you’re buying, remortgaging, or improving your property?

At Endurance Mortgages, we help clients understand how Green Mortgages work and whether they could genuinely save you money. Here’s what you need to know.

What Is a Green Mortgage?

A Green Mortgage is a mortgage product that rewards you for owning or buying an energy-efficient property. These properties typically have an Energy Performance Certificate (EPC) rating of A, B or C, depending on the lender’s criteria.

If your home meets the requirements, you may qualify for:

• A lower interest rate

• Cashback incentives

• Access to exclusive products

• Better lending criteria in some cases

Not every lender offers these products, but the number is growing as the UK pushes toward net-zero goals.

Myth: “Green Mortgages Are Just Marketing - They Don’t Save You Money.”

Fact: They genuinely can.

While the discount varies by lender, some Green Mortgages offer:

• Reduced interest rates compared to the lender’s standard product

• Lower arrangement fees

• Better affordability calculations because energy-efficient homes often have lower running costs

Even a small rate reduction can save you hundreds - sometimes thousands - over the term of your deal.

Why Lenders Reward Energy Efficiency

An energy-efficient home is usually:

• Cheaper to run

• Better insulated

• More sustainable long term

• Less likely to require major repairs related to heating or damp

This makes it lower risk for lenders.

For buyers, it means:

• Lower monthly bills

• A healthier home environment

• Potentially higher resale value

With EPC regulations tightening in the coming years, efficient homes are becoming even more desirable - and lenders want to encourage them.

Does Your Home Qualify?

Your eligibility often depends on your EPC rating.

Most Green Mortgage products require:

EPC A or B

You’ll usually qualify for the widest range of offers and the best incentives.

EPC C

Some lenders accept EPC C homes, especially for remortgaging.

New builds

Many new build homes automatically qualify due to modern building standards.

If you’re unsure of your EPC rating, you can check it for free on the Government EPC register - or we can help you find it.

What If Your Home Isn’t Energy Efficient?

You may still have options.

A growing number of lenders offer Green Home Improvement Mortgages, which provide:

• Cashback for energy-efficient upgrades

• Discounts after you improve your EPC rating

• Extra borrowing for improvements like insulation, double glazing, heat pumps or solar panels

Improving your EPC can help you:

• Reduce energy bills

• Increase your home’s value

• Access better mortgage deals in the future

A win-win for many homeowners.

When Green Mortgages Work Best

Green Mortgages can be especially beneficial if you are:

• Buying a new build

• Purchasing a modern, efficient home

• Remortgaging with an EPC A–C rating

• Planning eco-friendly home improvements

• Looking for ways to reduce your mortgage rate

If your property is older or needs upgrades, it may still be worth exploring your eligibility - criteria vary widely across lenders.

Why This Matters in 2025

With rising energy prices and tighter EPC expectations on the horizon, an energy-efficient home isn’t just a “bonus” - it’s a smart financial move.

Many landlords, buyers, and homeowners are already seeing the benefits.

Choosing the right Green Mortgage product could help you:

• Lower your monthly payments

• Improve long-term affordability

• Reduce environmental impact

• Enhance the appeal and value of your home

• Compare the full market, including specialist Green Mortgages

• Work out whether a green product is genuinely cheaper for you

• Explore remortgage or improvement-based options
