EPC Changes for Landlords: Why Reviewing Your Portfolio Before the New EPC System Arrives in 2027 Could Be a Very Smart Move
Major changes are coming to Energy Performance Certificates and the Minimum Energy Efficiency Standards for privately rented property.
By 1 October 2030, privately rented homes within scope will generally need to meet a significantly higher energy-efficiency standard or have a valid exemption in place.
You may have heard this described simply as:
“Rental properties will need an EPC C by 2030.”
Unfortunately, it isn't quite that simple.
The EPC itself is changing. The way properties are assessed is changing. HMOs that currently sit partly outside the EPC regime are being brought further into it. And landlords could ultimately be required to invest up to £10,000 per property attempting to meet the new standard.
But sitting within all of this regulation is an important transitional rule which could create a genuine opportunity for some landlords who understand it early.
At Nola Living, we think landlords should be looking at this now, rather than waiting until 2029 or 2030.
Not because everyone should immediately order a new EPC.
Quite the opposite.
The key is understanding what you already have, where your properties currently sit, and whether taking action before the reformed EPC system arrives in the second half of 2027 could put you in a stronger position.
The short version
The new PRS minimum standard is due to apply from 1 October 2030
The new standard will be based on new EPC metrics, rather than simply today's EPC rating
The maximum required investment is intended to be £10,000 per property, with an affordability adjustment for properties worth under £100,000
The maximum proposed penalty is £30,000 per breach, per property
Qualifying energy-efficiency expenditure from 1 October 2025 can count towards the future cost cap, although there are important exclusions
A privately rented property achieving EER C or above before 1 October 2029 can be treated as compliant until that EPC expires or is replaced
Reformed domestic EPCs are now expected to launch in the second half of 2027
Room-by-room HMOs which currently may not require a whole-property EPC are also intended to be brought into the EPC regime.
What is actually changing with EPCs?
At present, most landlords are familiar with a domestic EPC giving their property an overall Energy Efficiency Rating from A to G, largely based around the modelled cost of running the property.
The Government is fundamentally changing that approach.
New domestic EPCs are intended to contain four headline measures:
· energy cost
· fabric performance
· heating system, and
· smart readiness.
For privately rented property, the new Minimum Energy Efficiency Standard is then intended to operate on a dual-metric basis.
A landlord will first need to meet the required standard for fabric performance — essentially how effectively the building itself retains energy, taking account of elements such as insulation and heat loss.
The property will then need to meet the required standard through either the heating-system metric or the smart-readiness metric, with the landlord able to choose between the two routes.
That distinction matters.
Under the new regime, simply replacing a boiler or changing one element of the property may not necessarily make it compliant if the underlying fabric of the building performs poorly.
Equally, landlords shouldn't start spending thousands of pounds today on insulation, heating systems, solar panels or other improvements without understanding how their particular property is likely to be assessed.
Information first. Expenditure second.
When do landlords have to comply?
The current planned compliance date for privately rented properties within scope is:
1 October 2030
There is no longer a separate earlier deadline for new tenancies. The Government decided instead to introduce one compliance date.
However, there is another date which we think landlords need to have on their radar.
The Government originally intended to introduce the reformed domestic EPC in October 2026. Following further engagement with the industry, that has now been delayed until the second half of 2027.
And that creates an interesting period for landlords between now and then.
The EPC C transitional rule landlords need to understand
This is arguably the most important part of the announcement — and the part that could make early planning particularly valuable.
The Government has confirmed that privately rented homes achieving EER C or above on an EPC before 1 October 2029 will be recognised as compliant with the higher standard until that EPC expires or is replaced.
EPCs currently have a ten-year validity period, and the Government has confirmed that reformed EPCs will also retain that ten-year validity.
So, in principle, an EPC lodged in 2027 showing an EER C could potentially remain relevant well into the mid-2030s.
There are two important points to understand here.
The formal deadline is 1 October 2029 — not 2027
There is nothing in the Government's current policy saying landlords must obtain a C before summer 2027.
In fact, the Government intends to retain the existing EER as a legacy metric for a period after the new EPC system launches, and an EER C obtained on a reformed EPC before 1 October 2029 is also intended to qualify for the transitional protection.
So why are we interested in 2027?
Because we understand today's assessment system.
Once reformed EPCs arrive, properties will be assessed using a substantially different framework.
If we have a property today which is already capable of achieving a C — or could realistically achieve one following modest improvements — we think there is a sensible argument for investigating that position before the methodology changes.
That's very different from saying every landlord should rush out and commission a new EPC.
The part nobody else is telling you
There is a risk here that we think landlords need to understand before picking up the phone to an assessor.
A fresh EPC can replace the rating you were relying upon — and the result may be worse.
The Government's transitional policy specifically says that an existing EER C remains compliant until the relevant EPC expires or is replaced.
That matters.
A property which achieved a C several years ago won't necessarily achieve exactly the same rating if it is reassessed today.
Assessment methodologies have evolved, evidence requirements matter and the information available to an assessor can affect the resulting rating.
So imagine you have an EPC C with another six years remaining.
Ordering another EPC simply because you've heard about the 2030 changes could be completely unnecessary. Worse still, if the fresh assessment produces a D, you could potentially lose the C-rated certificate you were hoping would give you transitional protection.
That isn't an argument for doing nothing.
It's an argument for looking properly before commissioning anything.
The properties we're most interested in reviewing are likely to include those sitting at a high D, where modest and sensible improvements could realistically achieve a C, and C-rated properties whose existing certificates expire before or shortly after 2030.
If you already have a strong C with plenty of validity remaining, the best answer may simply be:
Leave it alone.
What about HMOs? This is particularly interesting
For HMO landlords, there is another significant change coming which has received considerably less attention.
Under the current EPC regime, Government guidance does not generally require an EPC for an individual room simply because that room within an HMO is being rented separately.
That has created an unusual position for many professional HMOs.
A tenant rents their bedroom. Gas and electricity are often included within the rent. They aren't therefore choosing a property based upon their expected individual gas and electricity bill in quite the same way as somebody renting an entire house.
Interestingly, landlords made precisely that argument during the Government consultation: HMO tenants commonly don't pay energy costs directly, so the usefulness of the EPC information to them is arguably more limited.
The Government considered that argument — and has decided that it nevertheless intends to change the rules.
It intends to require a valid EPC for the whole HMO when even a single room is let.
That does not mean an EPC for every bedroom.
It means one EPC covering the HMO as a whole.
The Government also intends this expanded EPC scope to interact with the Minimum Energy Efficiency Standards, although the precise transitional arrangements for properties newly brought into scope are still being finalised.
Section 21 has gone — so why bother with EPCs on HMOs now?
This is worth mentioning because it reflects how many landlords and agents have historically thought about EPC compliance.
For years, agents were particularly careful about providing prescribed documents such as EPCs because failures could have consequences when attempting to use Section 21.
Section 21 was abolished for the private rented sector in England from 1 May 2026, so that particular possession-related consideration has now disappeared.
But Section 21 was never the underlying reason EPC legislation existed, and its abolition does not remove EPC obligations where they otherwise apply.
For room-by-room HMOs, the more interesting point is that Government is now specifically intending to expand the EPC regime to cover them anyway.
So our question as HMO landlords and managers isn't simply:
“Do I legally have to obtain an EPC for this HMO today?”
It is:
“If Government has already told us that this property is going to be brought into the EPC regime, is there any benefit in understanding how it performs under today's methodology before that methodology changes?”
We think there very well could be.
Should HMO landlords get an EPC before the new system arrives?
This is an area where we think landlords should be cautious but proactive.
If an HMO doesn't currently require a whole-property EPC because its rooms are individually let, obtaining one voluntarily now could at least tell the landlord where the property currently stands.
If it achieves a C, excellent.
If it comes back as a high D and relatively modest work could push it into a C, we can investigate whether those improvements make commercial sense.
If it performs badly, we've identified a potential future capital-expenditure problem years before the compliance deadline.
That information alone can be extremely valuable.
There is also the potential transitional advantage of achieving an EER C before 1 October 2029.
However, we need to be precise here.
We would not currently tell an HMO landlord that obtaining an EPC C today guarantees another ten years under the future rules.
Room-by-room HMOs are specifically being brought further into a regulatory regime that many currently sit partly outside, and the Government has said that the detailed transitional arrangements for properties brought into scope still need to be finalised.
Things may change.
Further guidance may alter the position.
But from a portfolio-management perspective, we would still rather understand where an HMO stands before the assessment system changes than discover a major issue shortly before the 2030 deadline.
The cost of an EPC is relatively small.
The potential cost of getting the strategy wrong across a portfolio of HMOs could be anything but.
Could landlords really have to spend £10,000 per property?
Potentially, yes.
The Government has settled on a proposed maximum required investment of £10,000 per property over a ten-year period.
Its impact assessment estimates the average expenditure for properties below the new standard at approximately £5,400, although actual expenditure will clearly vary considerably depending upon the building.
There is some better news.
Qualifying expenditure on relevant energy-efficiency improvements installed since 1 October 2025 can count towards the first £10,000 cost cap.
However, there's an important qualification that landlords need to know:
spending between 1 October 2025 and 30 September 2029 on installing fossil-fuel heating will not count towards that cap.
So landlords should not simply assume that every pound spent improving a property's heating or energy efficiency since October 2025 automatically counts.
There is also an intended affordability protection for lower-value properties.
Where a property is worth below £100,000, the applicable maximum spend is intended to be £10,000 or 10% of the property's value, whichever is lower.
And if a landlord has undertaken the required relevant improvements up to the applicable cap and the property still can't meet the standard, they may be able to register a cost-cap exemption.
Perhaps most importantly:
£10,000 is a cap on required investment. It isn't a guarantee that £10,000 makes a property compliant.
If the property still falls short after the applicable expenditure, the exemption mechanism is what allows the property to continue being let.
Exemptions worth knowing about — particularly for older properties
This is particularly relevant in areas such as West Sussex and Surrey, where a considerable amount of housing stock is older, traditionally constructed, solid-walled or subject to planning and heritage constraints.
The Government intends to retain and expand several important exemptions.
One is a solid-wall-insulation exemption. Where solid-wall insulation is effectively the remaining measure needed to achieve the fabric standard, landlords are intended to be able to choose not to install it and register the appropriate exemption.
Another is the negative-impacts exemption, which can apply where evidence shows that a particular improvement would negatively affect the building or materially devalue it.
There is also the existing third-party-consent exemption, covering circumstances where necessary consent — for example from a tenant, superior landlord or planning authority — cannot be obtained.
These aren't loopholes.
Depending on the exemption, evidence, declarations and registration requirements apply, and different exemptions can have different validity periods.
But for somebody who owns a difficult period property and has quietly assumed that the only options are spending a fortune or selling it, the actual position may be considerably more nuanced.
The penalties are significant
This isn't something landlords will simply be able to ignore.
Under the Government's current policy, local authorities are intended to be able to impose a maximum financial penalty of:
£30,000 per breach, per property
That can cover non-compliance with the future PRS regulations as well as false or misleading information submitted to the exemptions register.
For somebody with one rental property, that's significant.
For somebody with ten, twenty or fifty properties, EPC strategy stops being an administrative task and becomes a portfolio-level risk-management exercise.
Is this another major cost being pushed onto landlords?
Partly, yes — and it's worth acknowledging both sides.
There are legitimate reasons to improve Britain's housing stock.
Better-insulated properties should cost less to heat, be more comfortable for tenants and waste less energy.
But there is another side to the argument.
Private landlords have already absorbed substantial increases in regulation, taxation, financing costs, maintenance costs and compliance obligations.
Asking landlords to find potentially thousands of pounds per property introduces another substantial capital requirement — particularly for owners of older housing stock where improvements may be technically difficult or disproportionately expensive.
Government policy explicitly links these reforms not only to reducing fuel poverty but to the UK's wider Net Zero and decarbonisation objectives.
Whether the policy survives completely unchanged between now and 2030 is impossible to predict.
Governments change.
Policies change.
Deadlines move.
The introduction of the new EPC system has already been delayed once.
There could be further changes, further exemptions or another change in political direction.
But hoping for a future Government U-turn isn't an investment strategy.
Landlords need to plan using the rules currently heading towards them while retaining enough flexibility to change course if Government policy changes again.
What we think landlords should do now
Our approach would not be to panic and start throwing money at insulation, solar panels, heat pumps or other improvements.
We think this requires something much more strategic.
It starts with information rather than expenditure.
First, pull every EPC across your portfolio.
Identify which properties already have a C, which are sitting at D but relatively close, and which appear likely to present a genuine challenge.
Then look at the expiry dates.
An EPC C expiring in 2035 is doing very different work for you from an EPC C expiring in 2028.
Then consider which properties might justify further investigation.
A high D might potentially reach C following relatively modest works.
An existing C with substantial validity remaining might be best left completely alone.
An HMO with no current EPC might warrant an assessment simply so that the landlord understands what they're dealing with before HMOs are brought further into the regime.
And only then should you consider whether commissioning a fresh EPC actually makes sense.
That decision needs to be made property by property, taking into account the existing rating, expiry date, likely new rating, recommended improvements and the remaining value of the certificate you already hold.
Don't wait until 2030
2030 sounds a long way away.
For property investors, it really isn't.
Major improvement works need budgeting.
They need scheduling around tenancies.
Portfolio landlords may need to spread significant capital expenditure across several years.
And before we even get to 2030, the domestic EPC system itself is scheduled to change in the second half of 2027.
That's why we think the sensible time to start looking at this is now.
Not necessarily to spend money.
Not necessarily to commission a fresh EPC.
But to understand the portfolio.
Over the coming months, we will be reviewing the EPC position across the properties we manage and identifying where an updated certificate, further advice or relatively inexpensive improvements could put a landlord in a materially stronger position ahead of the reforms.
We will also continue monitoring the legislation and Government guidance as the final methodology and HMO transitional arrangements develop.
Don't panic. Don't overspend. But don't ignore this either.
A note from Oli
As both a landlord and a letting agent, this is exactly the sort of regulation I think property owners need to get ahead of.
I'm not suggesting landlords rush out and spend £10,000 on every property, quite the opposite.
I'd also be wary of anyone simply telling you to order new EPCs across your entire portfolio without looking at what you already have first.
That could potentially cost you the rating you're currently relying upon.
What I will be doing is going through our own properties and the properties we manage, property by property, to work out where obtaining a fresh EPC under the existing system genuinely makes sense — and where it doesn't.
I'm particularly interested in our HMOs.
Some room-by-room HMOs may not need a whole-property EPC under today's rules, but the Government has already made clear that it intends to change that.
My thinking is therefore quite simple:
If we're likely to need these EPCs in the future anyway, I'd rather understand where those properties stand before the assessment system changes.
If they comfortably achieve a C, great.
If they're just short, we can investigate our options.
And if we've got a problem, I'd rather know about it in 2026 or 2027 than in 2029.
I also wouldn't be surprised if these rules change again before 2030.
This represents another potentially substantial cost for private landlords and forms part of a much wider Net Zero agenda which, in my view, deserves proper scrutiny — particularly when Government policy has the potential to require thousands of pounds of private investment into individual rental properties.
But we can't build a property strategy around the hope that a future Government changes its mind.
We can only work intelligently with what's currently in front of us.
And right now, I think there is a potentially valuable opportunity for landlords who look at this early, understand what they've got and make decisions property by property rather than waiting until the deadline.
