In January 2026, the UK government published the Warm Homes Plan — described as the largest home-upgrade programme in British history. While it may sound like another environmental initiative, it signals a shift in how rental property will be regulated, financed, and valued over the next decade.
For landlords and property investors, this isn’t abstract policy. It’s a roadmap to new obligations, new costs, and new commercial realities.
The government’s position — in plain terms
- Gas heating is being phased out
- Landlords are expected to invest in property upgrades
- Tenants are expected to benefit from lower running costs
- The financial responsibility sits primarily with property owners
“If you rent out property, you must provide a warm, affordable-to-run home.”
This is no longer guidance. It is a regulatory expectation.
What the Warm Homes Plan includes
- £15 billion of public funding for home upgrades by 2030
- 5 million homes targeted for improvement
- New minimum energy standards for the private rented sector and social housing
- EPC ratings as the primary enforcement mechanism
- Mandatory investment in insulation, low-carbon heating, solar generation, and energy storage
EPC is no longer just a certificate at point of sale. It is becoming the central lever for compliance, finance access, rentability, and long-term asset value.
The part that deserves more attention
When energy standards rise quickly, the market effect is predictable:
- push some landlords out of the market
- reduce rental supply
- increase rents
Despite this, the policy direction remains unchanged.
In simple terms: this is happening.
What this means for UK landlords
1) “Buy cheap, do nothing, hope for the best”
This approach is no longer viable. Deferred maintenance and poor energy performance now translate directly into compliance risk and financial exposure.
2) Ignoring EPC ratings
EPC performance increasingly affects:
- whether you can legally rent the property
- how easily you can refinance
- what interest rate you pay
- how attractive the asset is to future buyers
EPC C is emerging as the minimum survival tier. EPC B is becoming the commercial advantage tier.
The smarter way to approach upgrades
Step 1: Insulation first
Fabric improvements typically deliver the best EPC uplift per pound spent.
Step 2: Replace inefficient heating
Landlords will be looking for upgrade routes that are fast and practical. The best options tend to share:
- low installation cost
- no pipework or wet systems
- minimal disruption
- fast deployment
- low maintenance
Step 3: Add solar and storage where viable
Solar PV and compact battery storage can further improve EPC scores where viable.
Warm Homes Plan FAQ
What is the Warm Homes Plan?
The Warm Homes Plan is a UK government programme to improve energy efficiency across millions of homes, with EPC standards used as a key enforcement mechanism.
Does the Warm Homes Plan affect landlords?
Yes. It places increased responsibility on landlords to upgrade properties and meet higher minimum energy standards.
What EPC rating should landlords plan for?
EPC C is becoming the minimum acceptable standard, with EPC B offering a growing commercial advantage.

No. The policy does not mandate a single technology. EPC improvements can be achieved through multiple pathways.
What happens if a landlord does nothing?
Landlords may face restrictions on letting, higher compliance costs, and reduced refinancing or resale options.
Final thoughts
The Warm Homes Plan represents the biggest structural shift in the UK rental market in years.
Landlords who plan upgrades early will protect asset value, stabilise cashflow, and remain competitive.
