return to our customer websiteLast month, we continued our 2025 programme of Get more with Aldermore webinar sessions, this time focusing on sustainability and ‘green’ mortgages.
We were joined by Karina Gerdes, Head of Resilient Homes at Mortgage Advice Bureau, who shared her expertise in this growing sector.
She explained how brokers can better engage customers on sustainability by highlighting the savings on energy costs and showing them how an energy-efficient home mitigates future financial risks.
Here’s what we learned in this month’s session:
The mortgage industry is set to transform as sustainability becomes more important to homeowners, lenders, and therefore brokers.
Karina said that energy-efficient homes are not just better for the environment, they can offer significant cost savings to homeowners too and present a viable business opportunity for brokers.
Because of this, we’re beginning to see energy-efficiency being baked into mortgage criteria as running costs play a more important role in property affordability.
Potential regulatory changes could also have a direct impact on your clients’ finances.
Landlord clients might already be aware of the proposal to tighten Minimum Energy Efficiency Standards to an EPC C-rating by 2030, plus the government recently consulted on changing the assessment criteria for EPCs.
But new rules might not only be relevant to landlords. In Scotland, the Heat in Buildings Bill proposes minimum EPC requirements on owner-occupied homes as well as privately rented properties. This doesn’t cover the whole UK but gives us an idea of the direction of travel.
These regulations pose challenges for landlords, and potentially homeowners in Scotland, but they offer opportunities for brokers to support your clients, said Karina.
Impact on mortgage underwriting: Rule changes will undoubtedly impact mortgage criteria and feed into lender decision-making, because of the risk involved with providing funding for a property that doesn't meet a legislative standard.
Regulatory pressure: Highlighting the long-term benefits of energy-efficient properties and potential risks of ignoring this helps clients avoid foreseeable harm, which aligns with Consumer Duty principles.
Unlock additional revenue: By educating your clients about ‘green’ financing options, such as further advances, brokers have the chance to unlock additional revenue through higher procuration fees as well as helping them to future-proof their home.
Referral arrangements: There is a potential business case for brokers to form strategic partnerships with retrofit suppliers – you’re not expected to become a retrofit expert. Just as we already do with conveyancing and surveying, there's potential for referral as long as this is completely transparent and disclosed to the customer.
Boost retention: An increase in energy bills can impact the customer's ability to repay their mortgage. By addressing this, you are showing a commitment to your client’s financial health that can build trust and help retention.
The risks of ignoring this are stark from a climate and also a financial perspective.
Failing to engage with sustainability could have serious implications for brokers and their clients:
Clients might not ask for ‘green’ mortgages outright, but brokers can lead the way by reframing the conversation. Instead of asking clients if they’re worried about their EPC rating or a property’s carbon emissions, ask if they are worried about rising energy bills.
As Karina pointed out, there is a huge knowledge gap that you are perfectly positioned to fill, and she offered some practical tips:
Are we going to see mandatory ‘green’ mortgages?
Karina believes that most mortgages will be linked to energy efficiency, whether based on the EPC or on data from our smart meters.
Innovations like property-linked finance (where loans are tied to the property, not the borrower), as well as second charge mortgages and personal loans could also reshape the market.
By becoming trusted advisers on sustainability, brokers can retain clients and build long-term relationships. Mortgage Advice Bureau has already experienced this, Karina explained, with customers who would have taken a product transfer with their existing lender coming back to them to discuss energy efficiency and explore finance options.
Whether clients are eco-conscious or cost-conscious, you can adapt your approach and tailor the message to meet their priorities.
If you embrace this inevitable shift and educate your clients, you will not only protect their financial resilience but also help your own business to thrive.
