UK Warm Homes Plan: What Homeowners & Businesses Can Expect

The UK has just launched the largest home upgrade programme in the country’s history committing £15bn (US$20bn) in public investment to retrofit up to five million homes with solar panels, heat pumps and battery storage by 2030.

The Warm Homes Plan, which was announced by Prime Minister Keir Starmer and Energy Secretary Ed Miliband on 20 January, aims to lift one million families out of fuel poverty while accelerating the electrification of domestic heating.

The initiative comes at a moment when the UK is grappling with the legacy of volatile gas prices following Russia's invasion of Ukraine, which cost the UK £183bn (US$246bn) according to climate think tank E3G.

Three-tier approach targets renters and homeowners

The plan is has three main strands:

• Direct support for low-income households
• Universal access to government-backed loans
• New regulations for rental properties

Low-income families stand to receive fully-funded installations worth up to £12,000 (US$16,096), covering solar panels, batteries and heat pumps depending on suitability.

The government plans to focus on neighbourhoods too, rather than individual properties. As such, social housing residents could see entire streets upgraded simultaneously.

All UK homeowners will gain access to zero and low-interest loans for solar installations, with the government promising to triple rooftop solar capacity by 2030.

A £7,500 (US$10,061) universal grant for heat pumps will be available, including the first government support for air-to-air heat pumps that can cool homes in summer.

New protections for renters will require landlords to upgrade properties, with the government estimating this will lift 500,000 families out of fuel poverty by decade's end.

Currently 1.6 million children live in private accommodation suffering from cold, damp or mould.

Energy sector welcomes demand signal

Major energy companies have heartily endorsed the plan, viewing it as a catalyst for scaling deployment of technologies that remain expensive for many households.

"Electrifying homes is the best way to cut bills for good and escape the yoyo of fossil fuel costs," says Greg Jackson, Founder and CEO of Octopus Energy, the UK's largest heat pump installer.

Greg adds that with proper finance and simplified regulations, "heat pumps will increasingly be the best solution for many homes – as they are in other countries like Sweden, Norway and Finland".

Chris O'Shea, CEO of Centrica, emphasises his company's readiness with 7,000 unionised engineers.

"To achieve net zero, we must start where it matters most - in people's homes," Chris says.

"That means making the transition simple, affordable and within reach for every household."

Elsewhere, E.ON's UK CEO Chris Norbury highlights the importance of combining generation and storage with time-of-use tariffs.

"This approach puts control in customers' hands, pounds in their pocket and turns the energy system into something that works for people, not the other way around," Chris says.

Supply chain and manufacturing ambitions

The plan includes a target for 70% of heat pumps installed in Britain to be manufactured domestically, with government investment in the heat pump supply chain tripling to US$113m.

The government projects 180,000 additional jobs in energy efficiency and clean heating by 2030.

Charlotte Lee, CEO of the Heat Pump Association UK, describes the funding as "a strong signal to both industry and consumers that the shift to clean, electrified heat remains important for this Government".​​​​​​​

Solar Energy UK's Policy Director, Gemma Grimes, notes that almost two million small-scale solar installations have already been completed.

"The industry stands ready and able to build millions more by 2030," she says.

Implementation challenges remain

The plan will be delivered through a new Warm Homes Agency, consolidating functions currently scattered across the energy regulator Ofgem and other bodies.

Jonathan Brearley, who is CEO of Ofgem, confirms that existing experts would transfer to the new organisation to deliver "a clearer, more efficient system".

Regional mayors will lead local rollout, though details on financing mechanisms and consumer access to loans remain to be finalised later this year following consultations with financial institutions.

The government has also committed to implementing the Future Homes Standard in early 2026, requiring solar panels as standard on all new builds.

Critics of previous governments note that cancellation of the Zero Carbon Homes standard led to more than one million homes being built with higher running costs, leaving families exposed during the 2022 energy crisis.

Home insulation installations fell by more than 90% between 2010 and 2024.

Broader energy transition context

The initiative forms part of the government's wider clean power mission, with buildings currently responsible for over a fifth of Britain's territorial greenhouse gas emissions.

Adam Scorer, CEO at National Energy Action, calls it "a welcome, landmark occasion," though he cautions that "there is a lot of work to be done".

The plan seeks to reduce dependence on imported gas while providing resilience against future price volatility.

It also aims to address climate adaptation, with heat pumps offering cooling capacity for increasingly hot summers.

Total investment across the parliamentary term is projected to be around £38bn (US$51bn) when private sector contributions are included.

Whether the ambition can be realised depends on overcoming longstanding barriers to retrofit delivery, including skills shortages, supply chain constraints and consumer hesitancy about new technologies.
