The Warm Homes Loan Scheme is a government scheme offers loans to households for clean tech, including £15,000 for solar panels, £10,000 for air-source heat pumps, and £15,000 for storage batteries.

Here’s what it offers in full:

Clean technology Maximum available loan for households
Solar panels£15,000
Electrical storage battery£15,000
Air-water source heat pump£20,000
Air-air source heat pump £10,000
Ground-source heat pump£35,000
Biomass boiler£20,000
Heat network connection£7,500
Micro-renewable system£20,000

Yes, you will have to pay interest on whatever loans you take to install clean technology, but these interest rates will be 5% lower than what you would likely pay otherwise.

For example, if you were to borrow £10,000, at 8%, over seven years you would likely repay around £155 a month with a loan available right now from a high street bank outside the Warm Homes Loan Scheme. Through the Warm Homes Loan Scheme, you could save up to £285 a year on repayments.  

Everyone is eligible as these loans are available to households across the entire UK – in England, Scotland, Wales and Northern Ireland.  

There are 10 lenders who are offering loans through the Warm Homes Loan Scheme right now (although this could change as more lenders join).

  • Homeserve (partnering with E.On)  
  • Hometree Finance  
  • Propensio  
  • Secure Trust Bank  
  • Selina Finance  
  • South Manchester Credit Union 
  • Sunsave  
  • Tandem Bank
  • The Money Co-op  
  • This Bank  

Yes, if you get a loan through the Warm Homes Loan Scheme, you can combine with a grant from the Boiler Upgrade Scheme.

The Boiler Upgrade Scheme offers up to £9,000 towards the cost of a heat pump depending on what type of heating system you have. That means almost the upfront entire cost of a heat pump can be paid for by the government and you’d only have to pay back the balance left by the Boiler Upgrade Scheme.

The government says that all clean technology will be MCS certified, except for heat network connections. This will give consumers confidence that recognised technical and consumer-protection standards will be met, the government says.

Energy secretary Miatta Fahnbulleh said that energy is an “everyday essential that must be affordable for everyone”.

“These government-supported loans will help families across the UK upgrade their homes with no upfront costs to make them warmer and cheaper to run.”

He has also written extensively for consumer titles like City AM, The Morning Star, and The Daily Express.

He has represented The Eco Experts on national television several times, including the BBC’s Sunday Morning Live and ITV Tonight .

In 2020, he covered in detail the International Maritime Organisation’s (IMO) legislation on sulphur emissions and its effects on the global container shipping market as online editor of Port Technology International.

He also explored the initiatives major container ports and terminals have launched in order to ship vital goods across the world without polluting the environment.

Since then, he has reported heavily on the impact made by environmental, social, and governance (ESG) practices on the supply chain of minerals, with a particular focus on rare earth mining in Africa.

As part of this, in 2022 Max visited mines and ports in Angola to hone in on the challenges being faced by one of the world’s biggest producers of rare earth minerals.

His most recent sustainability-related work came much closer to home, as he investigated the eco-challenges faced by independent retailers in the UK, specifically looking at how they can cut emissions and continue to thrive.

Max lives in South London and is an avid reader of books on modern history. He has also recently learned to play the game Mahjong and takes every opportunity to do so. He is also yet to find a sport he doesn’t enjoy watching.
