The Warm Homes Plan is a major UK government initiative to be launched in early 2027. It represents the largest public investment in home energy efficiency and clean heating in British history, aiming to upgrade up to 5 million homes by 2030 and lift one million families out of fuel poverty.
While the overarching strategy runs through the end of the decade, January 2027 marks a major milestone where the initiative transitions into its fully consolidated, nationwide rollout phase.
| Question | Answer |
|---|---|
| What is it? | A major UK government programme to help pay for home insulation, heat pumps, solar panels, and smart heating controls, aimed at making homes cheaper to heat. |
| When does it start? | Early 2027, when it replaces and consolidates today’s separate, smaller grant schemes into one single programme. |
| How much money is involved? | £15 billion in direct government funding, rising to around £38 billion once local authority and private investment is included. |
| What can the money be used for? | Cavity, loft, and solid wall insulation; heat pump subsidies; solar panels with battery storage; and smart heating controls. |
| Who is it meant to help? | Around 5 million homes are expected to be upgraded by the end of the decade, including an estimated 1 million families currently in fuel poverty. |
| What’s changing for installers? | Up to 5,000 heat pump installers will go through a new vetting process by March 2027, alongside a new “Warm Homes Agency” offering advice and digital tools for homeowners. |
| What’s the longer-term goal? | Scaling up to 450,000 heat pump installations a year and 3 million homes with solar panels by 2030. |
Figures and dates are based on the government’s current plans as announced; details, funding levels, and timelines may be adjusted as the scheme is finalised closer to its 2027 launch.
What the Plan Offers
The plan is designed to provide energy-saving upgrades to households across all tenures, whether you own your home, rent privately, or live in social housing. If you let out a property, our guide to the EPC rules for landlords explains how the 2030 deadline fits alongside this funding.
Upgrades Covered:
- Insulation: Cavity wall, loft, and solid wall insulation to trap heat.
- Clean Heat: Subsidies and grants for switching to air-source heat pumps.
- Renewable Energy: Financial help to install rooftop solar panels and battery storage systems to keep electricity costs down.
- Smart Tech: Energy-efficient heating controls to optimise home energy use.
Why 2027 Matters: The Structural Reset
The programme is rolling out in stages, and a few major changes are locked in for the 2027/2028 period:
- Scheme Consolidation (2027): Existing independent funds, like the Warm Homes: Local Grant and the Warm Homes: Social Housing Fund, will be merged into a single, streamlined grant scheme for low-income households to reduce confusion and red tape.
- The Warm Homes Agency: A new national delivery agency will launch in 2027. It will provide a centralised digital platform, telephone hotlines, and impartial, high-quality advice to help all consumers choose the right retrofit options.
- Vetted Standards (March 2027): To protect consumers from rogue traders, the government has mandated strict vetting. For instance, the Microgeneration Certification Scheme (MCS) must vet all 5,000 UK heat pump installers by March 2027 to ensure high-quality workmanship.
Until the new scheme opens, the Boiler Upgrade Scheme remains the main grant for heat pumps in England and Wales. To see how today’s schemes compare with what is coming, read our BUS vs ECO4 vs Warm Homes Plan comparison.
Funding & The Bigger Picture
The government has committed £15 billion in direct public funding, but the ultimate goal is to unlock a total of £38 billion by partnering with local authorities, social landlords, and private finance mechanisms (such as the National Wealth Fund).
The Long-Term Goal: By shifting 3 million more homes to solar power and scaling up to 450,000 heat pump installations a year by 2030, the plan aims to break the UK’s reliance on volatile international gas markets and permanently lower household energy bills.
If you are hoping to apply, the best step for now is to check whether your local council is running a Warm Homes: Local Grant scheme. Be wary of anyone charging a fee to “pre-register” you for 2027 funding.
