If you're a private landlord with EPC D, E, F or G properties, there are two reasons to act now: a regulatory deadline approaching in 2028 and a grant scheme that could fund the required upgrades at no cost to you.
See our solar panel installation service for what funded upgrades typically include.
The 2028 EPC C obligation for landlords
Under proposed legislation, from 2028 all newly let properties in England must have an EPC rating of C as a minimum. From 2030, this will apply to all existing tenancies. Properties currently rated D–G will need significant energy efficiency improvements before 2028 or you risk being unable to legally let them.

How the Warm Homes Plan applies to landlords
Route 1 — Apply on behalf of your tenants
If your tenants have a gross household income at or below £36,000 and your property is EPC D–G, you can apply for the WH:LG on behalf of the tenancy. The grant funds the improvements — you don't pay. Tenants benefit from lower bills. Your property moves toward EPC C.
Route 2 — Apply directly as a landlord
In some local authority areas, landlords can apply for the WH:LG directly without tenant income assessment. Eligibility varies by area — contact Alliant Energy and we'll confirm for your postcode.
What upgrades can the grant fund for rental properties?
- Loft insulation and solid or cavity wall insulation
- Air source heat pumps (replacing electric storage heaters, oil or LPG)
- Solar PV panels and battery storage
- Heating controls and smart thermostats
A combination of insulation and a heat pump often achieves the required EPC C uplift in a single application.
Landlord with EPC D–G properties?
Alliant Energy can assess your portfolio and manage the grant application. Call 0800 088 4286.
What if my tenant doesn't qualify income-wise?
The Boiler Upgrade Scheme (BUS) gives any homeowner — including landlords — £7,500 toward a heat pump installation (rising to £9,000 for oil/LPG properties from July 2026), with no income test. For landlords who can't access the WH:LG, BUS is a viable alternative.
The commercial case for acting now
| Act now (2026) | Wait until 2027–28 |
|---|---|
| Fully funded upgrades available through WH:LG | Grant funding may be exhausted or reduced |
| Contractor availability — book now | High demand, possible delays and premium pricing |
| Tenant satisfaction and retention improves | Risk of void periods if property can't be let |
| EPC C achieved ahead of compliance | Possible enforcement action from 2028 |

Frequently asked questions
Can landlords apply for the Warm Homes Plan?
Yes. Landlords can apply for the Warm Homes Local Grant on behalf of their tenants or, in some areas, directly. The grant funds the full cost of eligible upgrades — no charge to landlord or tenant.
When is the EPC C deadline for landlords?
EPC C will be required for new lets from 2028, with all existing tenancies following by 2030. The exact commencement date depends on parliamentary confirmation.
