Green Mortgages
Green Mortgages: Expert Advice and Whole-of-Market Access
Expert Green Mortgage Advice and Application Support
Transform your home buying journey with environmentally conscious mortgage products that reward energy efficiency with better rates, cashback incentives, and additional borrowing options. Green mortgages reward homeowners with financial incentives such as lower interest rates, cashback, or larger loans for energy-efficient properties.
A green mortgage is designed to incentivize homebuyers to purchase energy-efficient properties, typically those with an Energy Performance Certificate (EPC) rating of A or B. Eligibility for green mortgages is often based on your home's energy efficiency and energy rating, with higher EPC scores qualifying for better terms. Green mortgages can offer benefits such as lower interest rates or cashback for homeowners who either buy energy efficient homes or make energy-saving improvements to their existing properties. With many UK lenders now providing green mortgages to encourage the transition to net-zero carbon emissions, there’s never been a better time to explore these eco friendly options. For more guidance on improving your home's energy efficiency and understanding energy ratings, consult the Energy Saving Trust.
Why Green Mortgages are Great for Your Property Purchase
Green mortgages are increasingly popular, with lenders offering green mortgages across the market to support the goal of bringing all homes in the UK to at least an EPC C rating by 2033. The UK government aims for all homes to achieve at least an EPC rating of C by 2035, which has led to an increase in the availability of green mortgage products from various lenders.
Lower Interest Rates
Green mortgages often come with lower interest rates for properties that meet energy efficiency standards, specifically those with an EPC rating of A or B. Lower interest rates associated with green mortgages can lead to significant long-term savings in total mortgage costs.
Cashback Rewards
Many lenders offer cashback incentives for borrowers who purchase energy-efficient homes or make energy-saving improvements, enhancing the financial appeal of green mortgages.
Additional Borrowing
Green mortgages can allow homeowners to borrow extra money specifically for energy efficiency improvements, making it easier to finance upgrades that enhance a property’s sustainability.
Future-Proof Investment
Energy-efficient homes have lower utility bills, reducing default risk, which may allow lenders to offer larger loans for such properties. These homes are considered less risky purchases for lenders, as they tend to maintain their value and cost less to operate, while less efficient homes may be seen as more risky purchases.
Professional mortgage adviser guidance ensures you secure the best deal on your green mortgage options while comparing the overall cost—including the mortgage rate—against standard mortgage products.
Green mortgages also play a key role in supporting a green society by promoting environmental responsibility within the housing and financial sectors.
Our Green Mortgage Services
Residential Green Mortgages
We provide expert guidance on green mortgage products for first-time buyers, home movers, and those looking to remortgage. To qualify for a green mortgage, the property's home's EPC rating—typically A or B—is crucial, as it reflects the home's energy efficiency. Improving your home's energy efficiency through upgrades such as insulation, heat pumps, or solar panels can help increase your home's EPC rating and make you eligible for green mortgage deals.
Our whole-of-market access means we search across all green mortgage lenders to find competitive mortgage rates, generous cashback rewards, and favourable terms for your energy efficient home purchase.
Green Buy-to-Let Mortgages
For property investors and landlords, green buy-to-let mortgages offer compelling benefits. With upcoming regulations requiring all privately rented properties to meet a minimum EPC C rating by 2030, investing in energy efficient properties now protects your portfolio from future compliance costs and potential fines of up to £30,000 per property.
Green credentials increasingly affect property value and tenant demand, making energy performance certificate ratings a critical consideration for the private sector landlord market.
Top 10 Green Mortgage Lenders in 2026
Several major lenders in the UK offer green mortgages, including Nationwide, Barclays, Co-operative Bank, Halifax, HSBC, NatWest, TSB, and Virgin Money, each providing various incentives for energy-efficient properties.
1. Nationwide Building Society
Up to £1,000 cashback for EPC A/B properties, plus their market-leading 0% interest Green Additional Borrowing for energy efficiency improvements between £5,000-£20,000
Nationwide Building Society has become one of the leading lenders in the UK when it comes to green mortgage initiatives and energy-efficient home incentives. The lender currently offers a combination of cashback rewards for energy-efficient properties alongside a highly competitive 0% Green Additional Borrowing scheme designed to help homeowners improve the energy performance of their homes.
Note: EPC (Energy Performance Certificate) regulations and the process for obtaining an EPC may differ in Northern Ireland compared to England and Wales. In all regions, accredited domestic energy assessors are used, and you can find more information or locate an assessor via the GOV.UK register.
Green Reward Cashback for Energy-Efficient Homes
Nationwide offers a Green Reward cashback incentive for buyers purchasing highly energy-efficient properties. The cashback amount depends on the property’s EPC and SAP rating:
- • Up to £500 cashback for properties with very high energy efficiency ratings (typically EPC A rated homes)
- • Up to £250 cashback for certain EPC B rated properties with strong SAP scores
In some cases, first-time buyers may also qualify for Nationwide’s standard mortgage cashback incentives, allowing eligible customers to receive up to £1,000 total cashback when combined with the Green Reward. This initiative is designed to encourage buyers to choose homes with lower energy consumption and reduced carbon emissions while helping offset some of the upfront moving costs associated with purchasing a property.
Nationwide’s 0% Green Additional Borrowing
One of the most attractive features offered by Nationwide is their market-leading 0% Green Additional Borrowing product. This scheme allows existing Nationwide mortgage customers to borrow between £5,000 and £20,000 interest-free to fund approved energy-efficiency improvements.
Eligible improvements may include:
The borrowing is available over either a 2-year or 5-year term, making it one of the most competitive green home improvement finance options currently available in the UK mortgage market.
Why Green Mortgages Are Becoming More Important
With energy bills remaining high across the UK and government focus increasing around sustainability and carbon reduction targets, green mortgages are becoming increasingly popular among both homeowners and property investors.
- • Lower monthly utility bills
- • Improved property value & Better EPC ratings
- • Increased mortgage attractiveness & Reduced impact
Important Considerations
Although Nationwide’s Green Additional Borrowing offers a 0% interest rate during the initial promotional period, it is still a form of secured borrowing against the property. Customers should always review the full terms and conditions carefully and consider how repayments may change once the initial period ends. As with any mortgage or additional borrowing product, seeking professional mortgage advice is highly recommended to ensure the product is suitable for your financial circumstances and long-term plans.

Our Green Mortgage Application Process
Step 1: Initial Consultation and EPC Assessment
During your initial consultation via phone or video call, or face to face we review your property’s EPC rating and assess your mortgage needs. An EPC is valid for ten years and is required whenever a property is built, sold, or rented, serving as a measure of the property’s energy efficiency. If you don’t have a current energy performance certificate EPC, we’ll explain how to obtain one and what ratings qualify for green mortgage products. Currently, only about 3% of the UK’s housing stock has an EPC rating of A or B, highlighting the potential for improvement in energy efficiency across homes.
Step 2: Whole-of-Market Green Mortgage Search
Our mortgage adviser searches all available green mortgage products, comparing green versus standard mortgage rates and benefits. While competitive, a green mortgage is not always the lowest-cost deal available compared to standard products—that’s why whole-of-market comparison is essential for saving money. We analyse interest rates, cashback offers, and additional borrowing options to find your optimal mortgage deal.
Step 3: Application Submission and Agreement in Principle
We handle your application submission and secure your Agreement in Principle, confirming the loan amount available to you. At Step By Step Financial Solutions, we believe in transparent and fair mortgage advice with no upfront costs to get started. Our fee is only payable once we successfully secure your formal mortgage offer from the lender.
We do not charge:
• Any fee for your initial mortgage consultation
• Any fee for arranging an Agreement in Principle (AIP/DIP)
This allows you to explore your mortgage options, receive professional advice, and understand your borrowing position before making any financial commitment.
There may be a fee for arranging a mortgage. The precise amount will depend on your circumstances, e.g. credit history and employment record. It will typically be £395 for purchases, £199 for remortgages and £495 for Buy to Let. We do not charge for a product transfer or an Agreement in Principle. We will confirm your fee in writing before any chargeable activity.
Full fee and regulatory informationRefer a Friend Programme: We also offer a Refer a Friend Programme, which may help reduce your mortgage advice fee. All referral rewards and discounts are subject to our referral programme terms and conditions.
Step 4: Completion Support and Ongoing Advice
From solicitor selection through to completion, we support you at every stage. Once your offer accepted is confirmed, we provide guidance on energy efficient home improvements, government grants available, and future remortgage opportunities to maximise your green home benefits.
