A major policy shift is on the horizon: the EPC C Proposal would require all privately rented homes in England and Wales — including holiday homes and short-term lets — to meet a minimum Energy Performance Certificate (EPC) rating of C by 2030.
This isn’t law yet — it’s still under consultation — but the direction is clear: energy efficiency is no longer optional for landlords although it might be for tenants.
If approved, this change will affect millions of properties, and the knock-on impact for the solar industry, housing market, and local economies could be huge.

Why EPC C Is on the Table
The government’s goal is to reduce energy use, cut carbon emissions, and tackle fuel poverty. According to estimates, around 2.6 million rental properties currently don’t meet the Energy Performance Certificate (EPC) C standard.
Upgrading properties could cost up to £15,000 each, which is the price cap for improvements, though the full financial picture remains unclear — especially for landlords with older properties in rural or coastal holiday areas.
And while no specific technology is being mandated, solar panels are high on the list of EPC-boosting upgrades.
The Coming Solar Surge
Although solar isn’t explicitly required, it’s one of the most effective ways to push a property up the EPC scale. That’s where timing becomes crucial.
If this EPC rule is approved, expect a rush of landlords and developers scrambling for solar installations — especially in regions packed with holiday lets. That means:
-
Longer wait times
-
Higher demand for installers
-
Potential supply chain delays
If you’re a business already thinking about solar, now’s the time to move. Beat the surge, lock in better prices, and avoid being stuck in the queue.

The Knock-On Effects for Tourism
Many holiday lets are older properties — quaint, charming, and often energy-inefficient. Retrofitting them to meet EPC C standards won’t be cheap, and some landlords may decide it’s not worth the hassle.
That’s bad news for:
-
Visitors facing fewer rental options
-
Local shops, restaurants, and attractions that rely on tourism
-
Hospitality businesses preparing for peak season
With fewer lettings available, local economies could feel the squeeze — especially in areas where tourism makes up a large share of business revenue.
How Could This Affect Your Business?
At Black Sheep Utilities, we track energy regulation changes because they shape the landscape for UK businesses. Here’s what this EPC proposal could mean for you:
1. Solar Bottlenecks Are Coming
If solar becomes the go-to upgrade, demand will surge, which means longer wait times and higher prices — so now is your window! Book in a call to discuss solar and we’ll help you plan, compare quotes, and secure installation before the rush begins.
2. Rising Costs in Rental Supply Chains
If landlords decide not to invest, housing stock — especially in holiday hotspots — may shrink. That could drive up prices and reduce footfall for local businesses.
3. Policy-Driven Shifts
More rules like this are on the way. Whether it’s EPCs, heat pumps, or zonal pricing, energy legislation is tightening. Get ahead of it now, and you’ll avoid last-minute compliance scrambles later.

Exemptions: When Might You Be Able to Delay or Skip It?
Landlords may be able to register an exemption from meeting Energy Performance Certificate (EPC) grade ‘C’ requirements in certain situations as with the current EPC ‘E’ upgrade scheme that has been in place since 2020. Here are the key scenarios:
-
Listed or Heritage Properties: If bringing a property up to Energy Performance Certificate (EPC) grade C would “unacceptably alter the character or appearance” of a listed building or heritage property, you may qualify for an exemption.
-
High Cost: Under current minimum Energy Performance Certificate (EPC) improvement standards if improvements costing up to £3,500 (including VAT) don’t bring the EPC rating to E, or if no improvements are possible within that cost an exemption can be registered. Although a price cap of £15,000 has been propsed for the new EPC ‘C’ standards it’s not yet clear if exemptions will be granted under the new scheme if it is implemented.
-
All Improvements Made: If all possible energy efficiency upgrades (up to the cost cap) have already been completed — or if none are feasible — and the property still doesn’t meet the standard.
-
Wall Insulation: If the only relevant improvements involve wall insulation and these would damage the structure or fabric of the building.
-
Third-Party Consent (Including Tenants): If the work requires permission from another party — such as a tenant, mortgage lender, or freeholder — and that consent is refused or granted only with unreasonable conditions. For example, if a tenant refuses upgrades, you can register a temporary exemption lasting as long as they remain in the property (typically up to five years), provided you supply evidence like a signed refusal.
-
Property Devaluation: If carrying out the necessary upgrades would reduce the property’s market value by 5% or more (evidence required).
-
New Landlord (Temporary): If you’ve recently become a landlord (e.g., through inheritance or purchase), you can apply for a six-month exemption. This allows time to either bring the property up to standard or register a longer-term exemption if applicable.
Final Thought: Take the Driver’s Seat
The EPC C proposal may not be law yet, but it suggests the direction government policy is heading — landlords, solar providers, and local businesses should start preparing.
