Keeping a MEES Evidence File: What Landlords Should Record Now

If you let a property in England or Wales, the energy efficiency paperwork you keep today may decide how easily you can prove compliance later. A MEES evidence file is simply one place where every EPC, invoice, assessor report and exemption record for a property is kept together, with dates, so that you can show what was done and when.

The government has set out plans to raise the minimum standard for private rented homes in England and Wales to the equivalent of EPC Band C, measured against the new EPC metrics, from 1 October 2030, with a cost cap and new exemptions. Those plans still need legislation, and Band E remains the legal minimum for now. But the direction is clear, and landlords who start recording evidence early will be in a far stronger position than those trying to reconstruct events from memory. This guide covers what to keep, why dates matter, and where evidence and exemptions meet.

Why an Evidence File Matters

Under the proposals, a landlord will not need to spend without limit. The government response sets a cost cap of £10,000 per property, with an affordability exemption where the cap is £10,000 or 10% of the property value, whichever is lower. Spending on relevant improvements from 1 October 2025 onwards will count towards the cap. These decisions still need legislation, so check the current official guidance before relying on them for a specific property.

Whatever the final detail, the principle is the same. If you want to show that you have spent what was required, or that an exemption applies, you will need records that stand up to scrutiny. A verbal agreement with a contractor or a letting agent is not evidence.

What to Keep for Each Property

Keep one folder, paper or digital, per property. It should hold:

the current EPC and every previous EPC you hold, with lodgement dates and certificate numbers
dated invoices and receipts for any work that affects energy performance, showing what was done, where, and what it cost
quotes you obtained, including those you did not proceed with, because they can support a cost cap or negative impact claim
written correspondence with contractors, agents and your assessor about what is and is not feasible
photographs taken before and after work, with the date visible or recorded
any exemption details, including the date it was registered and the date it expires

Do not rely on your letting agent to hold the only copy. Agents change, and a landlord who cannot produce a document in their own name is the one who carries the risk.

Dates Do Most of the Work

Three dates matter more than most landlords expect: when the work was done, when the EPC was lodged, and when any exemption was registered.

An EPC lodged before improvements were made will not reflect them, so a new assessment after work is often needed to show the result. Equally, an exemption only counts once it is logged on the government’s PRS Exemptions Register. Most last five years, so a diary entry for the expiry date is worth making now. Our guide to the landlord register and your EPC and MEES evidence explains how exemptions link to registration.

Evidence for Exemptions

The government has said new exemptions will cover cases where improvements would have a negative impact on the property, and solid wall insulation. Some exemptions are expected to last ten years rather than five. If you may need one, the evidence matters even more, because you will have to show why the work was not reasonable or possible.

That is where an independent assessment helps. A properly evidenced EPC, with clear site notes explaining the construction and any limits on what can be done, gives you something solid to point to. Since 1 October 2026, assessors have had to meet standardised minimum evidence requirements, which is good news for landlords because the report behind your EPC is better documented than it used to be.

Where This Sits Against the Wider Changes

Evidence is not only about the 2030 plans. The rental property register is rolling out by region from 15 December 2026, starting in the West Midlands. Landlords in Northamptonshire fall in the East Midlands phase from 15 February 2027, and landlords in Milton Keynes and Buckingham fall in the South East phase from 15 March 2027. You will be asked for your EPC and any exemption details. Our guide to the rental property register for Milton Keynes and Northamptonshire landlords sets out the local timetable. Separately, the government intends to require a valid EPC before a property is marketed, which will make keeping your EPC current more important. Our guide to EPC Band C for landlords covers what is proposed for 2030.

A Simple Routine to Start Today

Create a folder for each property and add the current EPC, its expiry date and its rating.
Gather any invoices, quotes and photographs from work done since October 2025 and file them by date.
Check whether any property relies on an exemption, and confirm it is logged on the PRS Exemptions Register.
Set a calendar reminder for every EPC and exemption expiry date.
Agree with your letting agent that you keep your own copies of everything.

This is a compliance routine, not an upgrade plan. It does not tell you what work to carry out, only how to be ready to prove what you have done.
