A blueprint to cut energy bills

A practical guide for how business and communities can work together to help households cut bills, build resilience and support the Warm Homes Plan.

The UK has some of the leakiest homes in Europe.

Precious heat that should be keeping us warm is escaping through uninsulated walls, draughty windows and poorly sealed roofs. That's bad news for bills, bad news for comfort and bad news for the planet.

Many households want to do something about it, and many forward-thinking businesses want to help.

This practical blueprint explores what happens when corporate partners, community organisations and local residents combine forces to tackle home heat loss. Featuring actionable insights from Thermal Detectives - a community pilot that lent out free thermal imaging cameras to spot home heat loss – this guide offers a step-by-step framework for corporate-community partnerships.

The pilot was successfully delivered in Bradford with support from TSB and B&Q, working in partnership with Business in the Community and Great Horton Park Chapel Cricket Club.

Who is this guide for?

  • Business and ESG leaders: looking for impactful, measurable community partnerships that drive social and environmental impact
  • Community groups & local councils: seeking a tested, replicable model to support residents, build local resilience, and lower energy bills

Why it matters

Today, 4.5 million households are living in fuel poverty (NEA), while up to £1 in every £4 spent heating a home is wasted.

Hubbub’s research has found three quarters of homeowners say they would make energy improvements if they had the right support. Yet three systemic barriers continue to hold people back:

  • Cost: navigating upfront expenses and understanding the potential return on investment
  • Support: knowing which solutions work for their property type
  • Trust: feeling confident in installers, technologies and advice.

With increasingly volatile energy prices we explored the role of trust to help cut energy bills for communities and their members, working with them as trusted messengers in their community.

6 steps to build replicable community energy efficiency projects

Build trust by taking the leap first! Upgrading community buildings first creates a powerful cascade of benefits:

  • Reducing costs so groups can focus on their mission
  • Building credibility by proving the technology works in practice
  • Creating visible proof that upgrades work

Make the savings tangible. Talk about money saved rather than kilowatt hours.

Recognise and value what each partner brings to the table.

Corporate partners can contribute far more than just funding – explore if expertise or products are equally valuable. Community organisations often have a physical hub, inbuilt links to the community and deep local knowledge.

Be clear on what each organisation can provide, have these conservations early and often, with check ins as the project evolves.

The right coordinator is the single most important factor in project success. Ideally, this should be someone already embedded within the community organisation.

A trusted insider can:

  • Recruit local participants and maintain project momentum
  • Organise engagement events and follow up on camera loans
  • Drive action through trusted face-to-face communications, that often outperform digital marketing

Every community is different. Avoid assumptions and design the project around the specific demographics of the local area, keeping in mind:

  • Home tenure patterns
  • Language and accessibility needs
  • Income challenges
  • Core motivations
  • Existing community rhythms and local events

Remember to listen to the communities' specific needs and challenges to design a project fit for purpose.

Energy efficiency is rarely the first reason people come along to a community centre. There needs to be an engaging, high-energy draw with a clear link back to trying out the cameras.

Successful activities in Bradford included:

  • ‘Can you beat the heat?’ Curry challenge – as the spice kicked in participants watched their face temperatures rise in real time on the thermal imaging cameras.
  • A half term draught excluder making workshop paired with a free hot chocolate station  naturally brought local families through the door.

Drop the confusing jargon and write like a human.

Instead of: "Building envelope heat loss"

Try: “Cold air sneaking in around your windows."

Share small specific actions people can take such as using draught excluder tape on their windows rather than catch-all terms or only highlighting the big changes.

Key findings from the Thermal Detectives pilot

The project ran at Great Horton Park Chapel Cricket Club, a vibrant community hub in Bradford. Before engaging residents, the club upgraded its own building, with over £2,000 saved through solar generation in 2025 alone.

"We used to turn the heating on in the morning to warm the club for evening events. Now we only need a couple of hours." - Les, Club President

  • 30 of 36 people (83%) reported high awareness of heat loss after using the camera.
  • The most common heat-loss discoveries were draughty windows and doors, inadequate or poor loft insulation, and missing or incomplete cavity wall insulation.

Bob borrowed a camera after seeing the project on Facebook.

  • The camera revealed heat escaping through this loft, alongside draughty windows and poorly sealed doors. His home was also missing cavity wall insulation.
  • He responded by sealing windows, draught-proofing doors and bleeding his radiators. Plus installing loft insulation and is keeping his eyes peeled for cavity wall insulation grants.

"It gave me the kick up the butt I needed." - Bob, Club Member
