If you live in Lancashire and you're wondering how to access the Warm Homes Plan, this is the guide for you. The scheme is delivered locally through Cosy Homes in Lancashire — and here's exactly how it works.
See our solar panel installation service for what gets installed.
What is the Warm Homes Local Grant?
The Warm Homes Local Grant (WH:LG) is the grant-funded arm of the government's Warm Homes Plan. Eligible households can receive up to £30,000 of fully funded home energy upgrades — no upfront cost, no repayment. It covers insulation, solar panels, air source heat pumps, battery storage and heating controls.
In Lancashire, the grant is administered by Cosy Homes in Lancashire (CHIL), a council-backed delivery body operating across all Lancashire districts.
Who qualifies in Lancashire?
- Gross household income at or below £36,000 — no documentation needed; you self-declare
- EPC rating of D, E, F or G (check yours free at epcregister.com)
- Owner-occupier or private tenant (with landlord's permission)
- Property in Lancashire — eligible postcodes include BB, BL, FY, LA, PR

How the WH:LG works in Lancashire
Step 1 — Application
You apply through Cosy Homes in Lancashire at chil.uk.com, or contact Alliant Energy directly and we'll handle the referral on your behalf.
Step 2 — Home survey
Once your eligibility is confirmed, a free survey is arranged, typically within five working days. A qualified assessor visits to check insulation, heating and EPC rating.
Step 3 — Funding confirmation
Cosy Homes issues a written offer confirming the measures covered and the grant value — up to £30,000. You don't pay anything.
Step 4 — Installation
An MCS-certified and TrustMark-registered installer is appointed. Alliant Energy is both — we install solar PV, heat pumps, batteries and insulation across Lancashire.
Step 5 — Post-installation
You receive MCS Certificates, warranty documentation and aftercare support. Your EPC is reassessed.
