About Warmify
Warmify is a service that helps households across England and Wales access free, government-funded energy upgrades. We work with councils and national schemes to deliver insulation, heating, solar panels, and energy advice to people who need it most.
We’re not a government department, but we deliver government-backed funding through trusted national and local partnerships, including with your local council.
All upgrades and support offered through Warmify are funded through schemes like ECO4, LEAP, Connected for Warmth and the Warm Home Local Grant. These are paid for by the government and major energy companies as part of their commitment to reducing carbon emissions and fuel poverty.
We work in partnership with local authorities, we’re not a sales company, and we never pressure anyone. Our advice is clear, our service is free if you qualify, and everything is designed around what’s right for your home.
All work is carried out by certified, experienced installers. We only work with trusted partners who meet industry standards.
Eligibility
You can use our free eligibility checker. We’ll ask a few simple questions about your household, income, and property to match you to the right scheme.
Yes. Some schemes (like ECO Flex and LEAP) use flexible criteria such as income level, health conditions, or postcode. We check all options to find what’s available for you.
An Energy Performance Certificate (EPC) shows how energy efficient your home is. Most schemes require your home to have a rating of D, E, F or G. If you don’t have one, we can arrange it for free.
Yes, but you’ll need your landlord’s permission for any work. We can contact them directly if needed.
Yes. Many types of insulation and heating upgrades can still be installed in flats, depending on building structure and permissions.
Yes. Landlords can receive full funding for one property, but may need to contribute 50% for additional homes. Tenants must also meet income criteria, and landlords cannot increase rent due to improvements.
Upgrades & Support
Depending on your eligibility and your home’s needs, you may qualify for:
- Loft insulation
- Cavity wall insulation
- Solid wall insulation (internal or external)
- Room-in-roof insulation
- Underfloor insulation
- Air source heat pumps
- A-rated boiler replacement
- Solar PV panels
- High heat retention storage heaters
- Heating controls (thermostats, TRVs, smart timers)
- Draught-proofing and ventilation
- Free energy-saving devices (like LED bulbs or radiator panels)
Yes—if your home qualifies for multiple improvements, you may receive a combination (e.g. insulation plus a new boiler or solar panels).
Yes. Many homes see a noticeable drop in heating bills, improved comfort, and higher EPC ratings after installation.
Most installations take a few hours to a few days, depending on the work. We’ll arrange everything at a time that suits you.
You’ll receive full documentation, warranties, and post-installation support. Some homes are also selected for an additional quality check.
The Process
Start with our eligibility checker. It only takes a few minutes and lets you know what funding you may qualify for.
Yes. If you’d like support, you can request a call from our friendly team who will guide you through the process or complete the application with you.
Yes, you may need to share proof of income, benefits, or tenancy. We’ll let you know exactly what’s needed and help you gather it.
A free visit from a trained energy assessor or installer to check your home’s suitability for upgrades. They’ll inspect insulation levels, heating systems, and general layout.
Never. Warmify is a no-pressure service. We only recommend upgrades that are fully funded and suitable for your home.
Funding & Schemes
We deliver energy support through:
- ECO4 – national scheme funded by energy companies
- ECO Flex – flexible version of ECO4, referred by local councils
- Connected for Warmth – offers insulation and heating nationwide
- LEAP – provides advice, referrals and smaller energy-saving measures
- Warm Home Local Grant – available in select areas (e.g. Portsmouth, Oxford)
Each scheme has slightly different criteria, funding levels, and available upgrades. Warmify checks them all to match you with the best option.
No. These are grants, not loans. If you're eligible, everything is fully funded and you won’t owe anything later.
Yes. Even if you’ve had support through another grant like HUG or earlier ECO phases, you may still be eligible.
If you qualify, 100% of the cost—including survey, equipment and installation—is funded.
Areas We Cover
We offer services across England and Wales, through national and local schemes.
The Warm Home Local Grant is currently available in:
- Portsmouth
- Oxford
These areas have additional funding and flexible support options.
You may still qualify for national schemes like ECO or Connected for Warmth. We’ll help you check based on your postcode and home type.
