EPC C by 2030: Your MK Upgrade Roadmap

The government has proposed an EPC C minimum standard for all rental properties by October 2030, and landlords who start planning now will avoid the expense and stress of a last-minute scramble.

What the 2030 rule means

From October 2030, landlords may need to achieve an Energy Performance Certificate rating of C or above for all tenancies, including existing ones. The target date remains provisional while the legislation moves through Parliament, but the direction is clear. Properties currently rated D, E, F or G will need work, and the clock is already ticking.

The £10,000 spending cap

The January 2026 Warm Homes Plan confirmed a £10,000 per-property spending cap, meaning landlords will not be required to spend beyond that threshold to meet the standard. If upgrades costing up to the cap still leave you below C, you will be exempt. Keeping invoices and an audit trail will matter when the time comes to demonstrate compliance.

Which upgrades move the needle

Loft and cavity wall insulation typically deliver the largest EPC improvement for the cost, often lifting a property by one or two bands. Upgrading to a modern condensing boiler or heat pump and replacing single glazing also make measurable differences. An EPC assessor can model the impact of each measure before you commit, so you spend on what actually counts.

Why 2026 is the year to budget and book

Waiting until 2029 means competing with thousands of other landlords for the same insulation fitters, heating engineers and grant-approved installers. Quotes will rise and lead times will stretch. Budgeting now, exploring finance options, and phasing work across void periods gives you control over cost and timing instead of accepting whatever is available in a rush.

Grants and finance worth checking

Several grant schemes support energy upgrades for rental properties, though eligibility and funding levels change regularly. It is worth checking the current position with your local authority, the Energy Company Obligation scheme, and any low-interest finance products aimed at landlords before paying full price. Even partial grant funding reduces the net cost and improves the return.
