The £10,000 EPC Cap: What Landlords Need to Know and What You Should Keep on File
For landlords, energy efficiency is no longer something that can simply be dealt with when an EPC expires. With the Government’s plans for the private rented sector, landlords need to start thinking strategically about their properties, their likely improvement costs and, importantly, the evidence they keep on file.
The Government has announced plans for privately rented homes in England and Wales to meet a new energy-efficiency standard equivalent to EPC Band C by 1 October 2030, unless a valid exemption applies.
A key part of the proposed framework is a £10,000 per-property cost cap.
But what does that actually mean for landlords?
And perhaps more importantly, what paperwork and evidence should you be retaining now?
What is the £10,000 EPC cost cap?
The Government’s proposed framework would require landlords to invest up to £10,000 per property in relevant energy-efficiency improvements to meet the new standard.
If a property still cannot achieve the required standard after the landlord has spent up to the applicable cap, the landlord may be able to register an exemption.
The £10,000 figure should therefore not be viewed as a £10,000 bill that every landlord will automatically receive.
Instead, it represents the maximum amount a landlord may be required to invest before certain cost-based exemptions can become available.
The Government estimates that the average cost of achieving the new standard will be considerably below the maximum cap, at around £5,400 per property.
The important message for landlords is therefore not “you will have to spend £10,000” but rather:
Understand your property’s position now, plan ahead and keep evidence of what you do.
The 2030 deadline is the important date
The Government has proposed a compliance date of:
1 October 2030
The higher energy-efficiency standard is intended to apply to privately rented homes across the sector, rather than only being triggered when a new tenant moves in.
This is important for landlords with long-standing tenancies.
The Government has also indicated that properties achieving EPC C under the existing Energy Efficiency Rating metric before 1 October 2029 will be recognised as compliant with the higher standard until the EPC expires.
That could provide a useful opportunity for landlords who are considering improvements now.
Don’t wait until 2029 to look at your EPC
One of the biggest mistakes a landlord could make is treating 2030 as a problem for the future.
Energy-efficiency improvements can take time.
Depending on the property, works could include:
Loft insulation
Cavity-wall insulation
Improved glazing
Heating-system improvements
Heating controls
Solar PV
Smart technology
Improvements to the building fabric
Specialist retrofit advice
Some properties will also present more complicated issues because of their construction, listed status, planning restrictions, solid walls, tenant considerations or the need for third-party consent.
The Government’s proposed approach places greater emphasis on the fabric of the property before landlords move on to heating or smart-readiness measures.
For landlords, this means early assessment is likely to be considerably more valuable than waiting until the deadline approaches.
What should landlords keep on file?
This is where good record keeping becomes particularly important.
If a landlord eventually needs to demonstrate compliance or rely upon an exemption, simply saying “I’ve spent a lot of money improving the property” is unlikely to be sufficient.
Landlords should be building a proper property energy-efficiency file.
1. Every EPC
Keep copies of:
The current EPC
Previous EPCs
Any EPC commissioned following improvements
The EPC recommendations report
The date each EPC was commissioned
The property’s EPC rating and relevant metrics
Do not rely solely on the EPC being available online.
Keep your own copy within the property’s compliance records.
2. Quotes for recommended works
If an EPC recommends improvements, retain the quotations obtained.
Ideally, keep:
The contractor’s quotation
Date of quotation
Description of the proposed works
Materials specified
VAT
Labour costs
Contractor details
Confirmation of whether the quotation was accepted or declined
For some existing exemptions, the Government already requires evidence such as multiple quotations.
For example, under the current high-cost exemption, landlords may need three quotations from different installers demonstrating that even the cheapest recommended improvement exceeds the applicable cost threshold.
The lesson for landlords is simple:
If you obtain a quote, keep it.
Even if you decide not to proceed with the work.
3. Invoices and receipts
If work is completed, retain the full financial evidence.
That should include:
Invoices
Receipts
Proof of payment
Contractor details
Dates of installation
Descriptions of works
VAT invoices where applicable
The Government’s proposals indicate that relevant improvement expenditure from 1 October 2025 may count towards the first £10,000 cost cap in certain circumstances.
Landlords should therefore avoid throwing away old invoices simply because the work has already been completed.
4. Before-and-after evidence
Where practical, retain photographs showing:
Before the improvement
and
After the improvement
For example:
Insulation
Windows
Heating systems
Boilers
Heating controls
Solar panels
Roof works
Wall insulation
Ventilation improvements
Photographs can provide useful supporting evidence of what was actually installed.
They should not replace invoices, certificates or formal documentation, but they can strengthen the property’s compliance file.
5. Building and installation certificates
Where relevant, retain certificates associated with improvement works.
Depending on the work undertaken, this could include:
Building Regulations completion certificates
Electrical certificates
Heating installation documentation
Boiler information
Warranties
Manufacturer’s certificates
Insulation certificates
MCS certification for relevant renewable installations
Planning permissions
Listed-building consents
Structural reports
Specialist retrofit reports
A landlord should aim to be able to answer: What was installed, when was it installed, who installed it, how much did it cost and what evidence do I have to prove it?
6. Evidence where works cannot be undertaken
This is potentially one of the most important areas.
Not every property will be capable of straightforward improvement.
There may be circumstances involving:
Listed buildings
Planning restrictions
Solid-wall construction
Structural concerns
Tenant consent
Superior landlord consent
Freeholder restrictions
Disproportionate costs
Potential damage to the property
Concerns regarding property value
Technical limitations
The Government has proposed that a number of exemptions will be available within the new framework.
These include circumstances involving the cost cap, property value, third-party consent and negative impacts, amongst others.
If a landlord believes an exemption may apply, keep the evidence that demonstrates why.
For example, if consent is required, retain:
Correspondence requesting consent
The response received
Reasons for refusal
Planning correspondence
Freeholder correspondence
Specialist reports
If an installer says a measure cannot safely be installed, retain the written professional advice.
A verbal conversation is much harder to evidence several years later.
7. Keep a record of rejected works
This is something we would strongly recommend landlords consider.
Suppose an EPC recommends three measures.
You obtain quotations and decide to proceed with two, while the third cannot reasonably be undertaken.
Keep a record of:
What was recommended
What was undertaken
What was not undertaken
Why it was not undertaken
The cost
The professional advice received
Any consent issues
Any relevant correspondence
A clear audit trail can be extremely valuable if the property’s compliance position is subsequently questioned.
8. Keep your exemption evidence together
An exemption should never simply be treated as a box to tick.
The Government’s current PRS exemption system requires landlords to register qualifying exemptions and provide supporting evidence depending on the exemption being relied upon.
The current register already requires information such as the property address, exemption type and a valid EPC, with additional evidence required depending upon the exemption.
For the future £10,000 cost-cap exemption, landlords should expect evidence of expenditure and the improvement journey to be important.
A landlord’s EPC compliance folder
We recommend landlords create a dedicated folder for every rental property.
It could contain:
EPC & Energy
☐ Current EPC
☐ Previous EPCs
☐ EPC recommendation reports
☐ New/reformed EPCs when applicable
Improvement Works
☐ Contractor quotations
☐ Alternative quotations
☐ Invoices
☐ Receipts
☐ Proof of payment
☐ Installation certificates
☐ Warranties
☐ Photographic evidence
Permissions & Restrictions
☐ Planning correspondence
☐ Listed-building correspondence
☐ Freeholder/superior landlord consent
☐ Tenant consent where relevant
☐ Contractor advice
☐ Specialist reports
Compliance & Exemptions
☐ Exemption registration
☐ Exemption supporting evidence
☐ Dates of registration and expiry
☐ Copies of correspondence with the local authority
☐ Evidence supporting the reason for exemption
This could ultimately make the difference between a landlord being able to demonstrate a clear compliance history and having to reconstruct years of expenditure and decisions retrospectively.
Don’t spend £10,000 just because you can
Another important point for landlords is that the £10,000 cap is not a spending target.
The objective is to meet the required standard using the relevant improvements.
Landlords should not assume that spending £10,000 automatically means the property will be compliant.
The correct approach is:
Assess → Plan → Obtain evidence → Improve → Reassess → Record
rather than simply:
Spend £10,000 and assume compliance.
What should landlords do now?
For landlords with properties below EPC C, now is a sensible time to review the portfolio.
We recommend:
1. Identify properties below EPC C
Create a portfolio list showing each property’s current EPC rating and EPC expiry date.
2. Review the recommendations
Look beyond the headline rating and understand what the EPC is actually recommending.
3. Obtain professional advice
Where significant works are involved, consider obtaining advice from appropriately qualified energy-efficiency or retrofit professionals.
4. Start building your evidence file
Keep quotations, invoices, certificates, correspondence and photographs.
5. Don’t assume an exemption will automatically apply
An exemption needs to meet the applicable criteria and, where required, be properly registered.
6. Review the position regularly
Energy-efficiency policy is developing, and landlords should keep their properties under review as further regulations and technical guidance are introduced.
The professional landlord will be the prepared landlord
The introduction of the £10,000 cost cap should not be viewed simply as another financial burden.
For landlords, it is also a reason to take a more structured approach to property management.
A well-maintained compliance file gives a landlord something extremely valuable:
an evidence trail.
When a property has been improved over several years, it can otherwise become difficult to remember exactly what was done, when it was done, what it cost and why certain measures were or were not undertaken.
By keeping the evidence together now, landlords can make future compliance considerably easier to manage.
And for landlords who use a professional letting agent, this is an area where good property management should extend beyond collecting rent and arranging repairs.
Your property should have a compliance history, not simply a collection of certificates.
With the 2030 deadline approaching, landlords who understand their current EPC position, plan their improvements and retain the supporting evidence will be in a far stronger position than those who leave everything until the last minute.
If you are unsure what the proposed EPC changes could mean for your rental property, speak to a professional letting agent or appropriately qualified energy-efficiency specialist before committing to significant expenditure.
