EPC Ratings: Energy efficiency is becoming part of the financial assessment of a rental property.
An EPC rating can affect the work a landlord may need to complete. It can also influence valuation, refinancing plans, available mortgage products and future portfolio decisions.
For mortgage advisers, the important question is no longer whether EPC rules may change. It is how landlords can prepare without making rushed or unsuitable financial decisions.
At a Glance
- Privately rented homes in England and Wales must currently meet EPC E, unless a valid exemption applies.
- The government has confirmed a target requiring eligible rented homes to meet the equivalent of EPC C by 1 October 2030.
- Advisers should record the EPC position during the fact-find process.
- Landlords may need to consider improvement costs before refinancing or selecting a new fixed term.
- Green mortgage incentives vary between lenders and should not replace a full suitability assessment.
- Portfolio landlords may need a property-by-property funding plan.
What Is the Current EPC Requirement for Landlords?
Privately rented homes in England and Wales must currently achieve at least EPC E before they can normally be let.
A landlord may be able to register an exemption where the property qualifies under the relevant rules. An exemption should not be assumed without checking the supporting conditions and evidence.
The government has confirmed that private rented properties will need to meet the equivalent of EPC C by 1 October 2030, subject to the updated regulations and applicable exemptions.
The confirmed policy replaces earlier proposals that referred to separate deadlines for new and existing tenancies.
Landlords and advisers should refer to the government’s minimum energy-efficiency guidance for domestic rented property before relying on older articles or proposed dates.
Why EPC Ratings Matter to Mortgage Advisers
An EPC is not simply a certificate kept with the tenancy documents.
It may indicate that a landlord will need to fund insulation, heating controls, glazing or other improvements. These costs could affect available capital, borrowing requirements and the timing of a mortgage application.
Advisers should establish:
- the property’s current EPC rating
- when the certificate expires
- which improvements have been recommended
- whether works have already been completed
- the landlord’s estimated improvement budget
- whether the property may qualify for an exemption
- whether other properties in the portfolio also need work
The findings should form part of the wider borrowing discussion.
Advisers can review relevant criteria through Connect’s buy-to-let mortgage support.
How EPC Improvements Can Affect Mortgage Planning
A landlord approaching a remortgage may also be planning energy improvements.
The order of these decisions matters.
For example, a long fixed-rate period could restrict access to the property’s equity if the selected lender does not offer a suitable further advance. Early repayment charges may also make refinancing costly.
Advisers should therefore consider whether the landlord may need:
- a further advance
- a remortgage with capital raising
- short-term finance for renovation
- a product with lower early repayment charges
- a lender that accepts the property before improvements
- a lender offering incentives after the EPC rating improves
The cheapest initial rate may not provide the most practical long-term structure.
Good mortgage planning considers not only today’s payment, but also the decisions the borrower may need to make later.
EPC Ratings and Lender Criteria
Lender approaches are not identical.
Some lenders offer green mortgage products or incentives for properties rated A to C. Others may provide cashback or improved pricing after qualifying work has been completed.
However, advisers must check the detail.
A lender may require:
- a valid EPC before application
- an updated certificate after the work
- a minimum property value
- approved types of improvement
- completion within a set period
- invoices or evidence of expenditure
- the property to meet standard valuation requirements
An incentive should not be treated as evidence that the overall product is suitable.
For more complex properties or portfolio cases, advisers can review Connect’s specialist buy-to-let guidance.
Portfolio Landlords Need a Property-by-Property Review
The potential cost becomes more significant when a landlord owns several properties.
One property may only require modest changes. Another may involve solid walls, older heating systems or restrictions linked to the building’s construction.
A portfolio review should record:
- The current EPC rating for each property.
- The certificate expiry date.
- Recommended improvement measures.
- Estimated costs.
- Current mortgage deal end dates.
- Available equity and rental income.
- The planned order of work.
This creates a timetable rather than a last-minute funding problem.
Advisers can also use the buy-to-let rental calculator when reviewing rental coverage. The result remains an illustration and does not replace lender criteria.
Should Landlords Complete EPC Work Immediately?
Not every recommendation on an EPC will suit every building.
Landlords should obtain suitable property and installation advice before commissioning expensive work. This is especially important for older, listed or unusually constructed properties.
However, waiting until close to the 2030 deadline may create other pressures. Demand for assessors, contractors and materials could affect project timing and cost.
A measured approach is usually more useful:
- confirm the current certificate
- identify realistic improvements
- obtain cost estimates
- check available grants or schemes
- consider the mortgage position
- schedule work in a practical order
- obtain a new EPC when appropriate
The objective is not to predict every future lender rule. It is to ensure the landlord has enough information to make informed decisions.
When Should an Adviser Raise the EPC Discussion?
The EPC conversation should begin when an adviser first reviews the property or portfolio.
It should not be left until the mortgage offer stage.
Useful review points include:
- a property purchase
- a remortgage
- a product transfer
- capital raising
- portfolio restructuring
- incorporation into a limited company
- the purchase of an older property
- an approaching EPC expiry date
Early discussion gives the landlord more time to compare costs, borrowing routes and suitable lender criteria.

Supporting Landlords Through EPC Change
EPC reform connects property condition with borrowing strategy.
The certificate shows the present position. The mortgage structure may determine how easily the landlord can fund the next step.
Advisers who record EPC information early can help clients assess improvement costs, mortgage flexibility and future refinancing needs together.
Connect network members can access specialist support for buy-to-let, portfolio and complex property cases. Advisers interested in joining the network can review why advisers join Connect.
Mortgage availability and lender criteria vary. Property owners should obtain suitable mortgage, legal, tax and property advice before acting.
