Making your home warmer, more efficient, and ready for the future starts with good information. Whether you’re looking at small upgrades or planning a full retrofit, our resources hub brings together clear guidance on the key steps – from insulation and ventilation to renewable energy and smarter heating – so you can make informed choices.

Insulation and the fabric of your home

Improving walls, windows, roofs, and floors helps your home stay warm in winter and cool in summer.

• 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

Modern heating systems and renewables can cut running costs and carbon.

Heating

• Air Source Heat Pumps: Low-carbon heating with smart controls.
• Which heat pump is right for your home?: Explore air, ground, and water source systems.
• How loud is a heat pump?: What to expect and how to minimise noise.
• Living with a heat pump: Real stories from our customers on how combining a heat pump with insulation, solar panels, and smart controls has transformed comfort and energy bills.

Renewable energy

• 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.
• Solar PV guide – Download PDF: How solar panels and battery storage work, and what to consider before installing.

Planning improvements

Good planning avoids wasted money and missed opportunities.

• Why an EPC rating doesn’t tell you the whole story: Understand the limits of EPC ratings.
• 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.
• Heritage buildings – Download PDF: How to improve older homes while protecting their character.
