Making your home warmer, greener, and easier to run starts with good information. This resources page brings together everything you need to explore energy-saving improvements – from simple fixes like loft insulation to bigger steps like solar panels or heat pumps.

Whether your goal is lower bills, more comfort, or cutting carbon, you’ll find clear guidance here to help you choose the right steps, in the right order, for your home.

Insulation and the fabric of your home

Good insulation is the foundation of an efficient home. By tackling draughts, walls, floors, and roofs, you’ll stop heat escaping and make every other upgrade – from heating to solar – work harder for you.

• Floor insulation: Reduce draughts and heat loss, especially in older homes with timber floors.
• Loft or roof insulation: Cut heat loss by up to a quarter with simple but effective upgrades.
• Solid wall insulation: Reduce heat loss in older homes – best planned as part of a whole-house approach.
• Cavity wall insulation: Fill wall gaps to cut heat loss by a third when conditions are suitable.

Smarter heating and energy

Once the fabric of the home is improved, modern heating systems can make a big difference. Heat pumps, for example, can heat (and even cool) homes efficiently – especially when combined with solar panels and smart controls.

Heating

Renewable energy

Adding renewable energy helps you generate your own power, cut reliance on the grid, and bring down running costs – while reducing your carbon footprint.

• Solar thermal system: Use the sun’s energy to heat your water.
• Solar panels: Generate your own electricity and reduce your carbon footprint.
• Will solar PV save you money?: Find out what kind of savings you could make, and whether solar is right for your home.

Planning improvements

Good planning avoids wasted money and missed opportunities. By thinking through your options in advance, you’ll make upgrades that fit together properly and deliver the biggest benefits.

• Home refurbishment vs retrofit: What these terms really mean.
• Where is your home using the most energy?: Track energy use to make smarter decisions.
• Double or triple glazing?: Which option makes sense for your home.
• Understanding LED lighting: Smart, efficient lighting choices.
• Eco-friendly home improvements: Plan for a home that’s comfortable year-round.
