I want to invest in energy‑saving upgrades and modern technology
Modernising your home with energy‑saving upgrades can reduce energy use, improve comfort and make your property more attractive to future buyers. Options range from technologies such as solar panels, battery storage and heat pumps, to fabric improvements like insulation. The right mix will depend on your home, your budget and what you want to achieve.
You can use the Energy Saving Trust’s solar calculator to get an estimate of installation costs and potential savings for your home.
Fabric upgrades vary widely in cost and payback. Loft insulation is relatively low‑cost and usually pays for itself within a couple of years. Other measures, such as solid wall insulation, may not ‘pay back’ financially but can make your home warmer, healthier and more comfortable. It’s important to think about the benefits that matter most to you — lower bills, comfort, carbon savings, or future‑proofing.
Independent research on potential savings
A 2025 analysis by OVO Energy, a major UK energy supplier, modelled the impact of installing a package of home‑energy improvements such as insulation, solar panels, and a heat pump.
Their modelling suggested that, although upfront costs can be significant, households could recover these costs over time through reduced energy use, with potential long‑term savings compared with continuing to use oil or gas heating. You can read the analysis here.
Actual outcomes will vary depending on the home, installation costs, and energy use.
Start with understanding what your home needs
Before deciding what to install, it’s important to understand what your home actually needs. An EPC, Home Energy Hub self‑assessment, or a full Retrofit Assessment can help you identify the improvements that will deliver the best results for your situation.
You can explore the steps involved in our Retrofit Journey to understand how assessments, planning, and installation fit together.
For some households the priority will be reducing running costs, for others it may be the quickest return on investment, and for landlords it may be ensuring their property meets future standards.
Heritage-sensitive upgrades
Older and historic buildings often require a more careful approach when making energy improvements. Traditional materials such as solid brick, lime mortar and timber behave differently from modern construction methods and need to be considered during retrofit work.
Heritage sensitive upgrades aim to improve energy efficiency while protecting the character and condition of the building. This may involve using breathable materials, carefully designed insulation or upgrades that minimise changes to the original structure.
Specialist advice is often recommended to ensure improvements are appropriate for the property.
