EPC Axed: When rules change, landlords often feel relief first and ask questions later.

The 2023 decision to axe the proposed EPC C deadlines gave many buy-to-let landlords breathing space. It removed an immediate pressure point. Yet it did not remove the wider question behind the rule: how efficient, lettable, financeable and future-ready is the property?

For landlords, the lesson is simple. A delayed rule is not the same as a cancelled risk.

At a glance

• The proposed EPC C deadlines for private rented homes were dropped in 2023.
• Landlords still needed to understand the existing EPC rules.
• Energy efficiency could still affect rent, resale value, tenant demand and mortgage planning.
• Some lenders were already paying closer attention to EPC ratings and property condition.
• Portfolio landlords had the most to review because costs could multiply across several properties.
• The decision was not a reason to ignore energy performance. It was a reason to plan with more care.

What Does EPC Axed Mean for Landlords?

“EPC axed” referred to the 2023 decision to remove proposed rules that would have required many privately rented properties to reach EPC band C by set deadlines.

Before the change, many landlords expected new tenancies to need an EPC rating of C or above by 2025, with existing tenancies following later. The decision reduced the short-term regulatory pressure on landlords who owned older, less efficient rental homes.

That mattered because many buy-to-let properties are Victorian terraces, converted flats, older houses, HMOs or homes with limited improvement options. In these cases, reaching EPC C can involve insulation, glazing, heating upgrades, ventilation work or changes to lighting and controls.

The cost is not always simple. A small flat may need limited work. A larger older house may need a staged plan. A listed or unusual property may need specialist advice before improvements are made.

Does EPC Axed Remove All Landlord Responsibilities?

No.

The decision did not mean landlords could ignore energy performance. An Energy Performance Certificate still plays a practical role when a property is sold or rented. Landlords can check official requirements through GOV.UK guidance on Energy Performance Certificates.

For buy-to-let landlords, the important point was not only legal compliance. It was commercial judgement.

A property with a weak EPC rating may still raise questions around:

• tenant running costs
• future improvement costs
• resale value
• rental appeal
• lender appetite
• valuation comments
• long-term portfolio strategy

A rule can be axed quickly. A cold, inefficient property cannot be changed overnight.

Why landlords Should Not Treat the Decision as a Full stop

The 2023 announcement gave landlords more time, but time only helps when it is used well.

Energy efficiency sits between regulation, lending, valuation and tenant demand. It is not just an environmental label. It is a measure of how a property performs in everyday life.

A tenant may not ask about policy, but they may ask about bills. A lender may not reject a case on EPC alone, but the property still forms part of the risk assessment. A buyer may not demand perfection, but they may compare the likely upgrade cost against the asking price.

That is why the EPC axed decision should be seen as a pause, not permission to stand still.

How EPC Ratings Can Affect Buy-to-Let Mortgage Planning

A buy-to-let mortgage is based on more than the interest rate. Lenders may consider rental income, property type, valuation, deposit, ownership structure, landlord experience and wider portfolio strength.

EPC ratings can form part of that wider property picture.

Some lenders may offer products linked to stronger EPC ratings. Others may ask more detailed questions when the property is older, unusual, or already costly to maintain. A low EPC rating may not stop a mortgage application on its own, but it can add another point for review.

Landlords comparing new purchases, remortgages or refinancing options can read more about buy-to-let mortgage advice before making decisions.

Portfolio Landlords May Need a Wider EPC Review

The EPC axed decision may have felt helpful for landlords with one property. For portfolio landlords, the issue was more complex.

One property needing £4,000 of work is a cost. Ten properties needing work becomes a strategy question.

A portfolio review can help landlords understand which properties may need attention first. The review may include:

• current EPC ratings
• remortgage dates
• rental yield
• likely improvement costs
• property age and construction
• local tenant demand
• exit plans
• future borrowing needs

A landlord may decide to improve one property, refinance another, sell a weaker asset, or hold funds for future works. The right answer depends on the numbers.

Landlords with several mortgaged rental properties can explore buy-to-let portfolio mortgage options when reviewing borrowing and long-term plans.

Should Landlords Still Improve EPC Ratings?

In many cases, yes, but not blindly.

A landlord should not spend money just because a headline creates pressure. The better approach is to look at the property, the likely cost, the expected benefit and the future plan.

Some improvements may be practical and cost-effective. Examples may include loft insulation, heating controls, LED lighting, draught-proofing, or improved hot-water insulation. Larger works, such as wall insulation, new heating systems or glazing, may need more thought.

The key question is not simply, “Can this improve the EPC?”

The better question is, “Does this improve the property as an investment?”

A stronger EPC rating may support lower running costs, a better tenant experience and stronger future marketability. It may also help when lenders offer products linked to greener homes. Landlords can read more about green mortgages, in which energy efficiency is part of the mortgage conversation.

What Should Landlords Do After EPC Axed?

The practical response is to review before reacting.

Landlords may wish to:

• Check the current EPC rating for each rental property
• Read the assessor’s improvement recommendations
• Separate low-cost works from major upgrades
• Compare improvement costs with rental income and property value
• Check mortgage renewal dates
• Consider whether the property still fits the portfolio
• Keep records of works completed
• Speak with a mortgage adviser before refinancing or buying again

The most important step is to avoid making decisions in isolation. EPC work, borrowing, tax, rent, repairs and exit plans can all affect each other.

For example, a landlord planning to remortgage may want to know whether improvement works could affect valuation, rent, affordability or lender choice. A landlord buying a new rental property may want to factor EPC upgrade costs into the purchase price from day one.

The buy-to-let affordability calculator can help landlords form an initial view of borrowing, but it should not replace tailored mortgage advice.

Should Landlords Celebrate or Exercise Caution?

Landlords had reason to welcome the 2023 decision. It reduced immediate pressure and gave breathing space at a time when mortgage rates, maintenance costs and tax changes were already affecting the buy-to-let market.

But celebration without planning can become expensive later.

A good landlord thinks beyond the next rule. A good investor thinks beyond the next mortgage product. A good property plan asks whether the asset is still strong enough for the years ahead.

EPC axed did not make energy efficiency irrelevant. It made the timing less urgent, but the practical question remained.

Is the property fit for tenants, lenders and future buyers?

When a Mortgage Adviser May Help

A mortgage adviser cannot tell a landlord which insulation to install. That is a technical property matter.

However, an adviser can help landlords understand how the property fits into the mortgage market. This may include lender criteria, rental stress testing, remortgage options, limited company borrowing, portfolio finance and the possible role of green mortgage products.

FAQs

Was EPC C scrapped for landlords?

The proposed EPC C deadlines were dropped in 2023. This reduced immediate pressure on many private landlords, but it did not remove the need to understand EPC rules or property energy performance.

Does EPC still matter for buy-to-let landlords?

Yes. EPC ratings can still affect tenant appeal, running costs, property value, improvement planning and mortgage discussions.

Should landlords still improve rental properties after EPC axed?

Landlords should consider sensible improvements where they support the property’s long-term value, tenant comfort and future marketability. The decision should be based on cost, benefit and the wider property plan.

Can EPC ratings affect buy-to-let mortgages?

They can form part of the wider picture. Lenders may consider property condition, valuation comments, rental strength and product rules. Some products may also be linked to stronger EPC ratings.

What should portfolio landlords do first?

Portfolio landlords should list each property’s EPC rating, mortgage renewal date, likely upgrade cost and rental yield. This helps identify which properties need attention first.
