Older homes are packed with charm and character, but this often comes with a compromise on energy efficiency. If you live in a Victorian terrace, a 1930s semi, or even a post-war build, you might find it’s harder to keep warm in winter or cool in summer. The good news? You don’t need a full retrofit or an endless budget to make meaningful improvements. Here’s how to boost energy efficiency in your older home, step by step.
Conduct a DIY energy audit
Before looking at any upgrades, walk through your home to identify potential problem areas. Common issues in older homes include:
- Draughts around windows and doors
- Poor loft insulation
- Cold floors and uninsulated walls
- Single-glazed windows
- Inefficient heating systems
Take a notepad with you and list down the problems, making a list of improvements that you can tackle right away and those that might need a tradesperson.
Prioritise insulation improvements
You don’t have to tear down walls to make an impact. Focus on affordable insulation upgrades:
- Loft insulation is one of the most cost-effective ways to retain heat. Check if yours meets the recommended 270mm depth.
- Pipe and water tank lagging is cheap and easy to install, lagging helps reduce heat loss and prevents pipes from freezing.
- Thermal curtains or blinds help trap warm air in during winter and block heat out during summer.
Combat drafts
Older homes often suffer from leaky windows, under-door gaps, and unused chimneys. Some quick wins include:
- Draught excluders for doors and letterboxes
- Silicone sealant or foam strips around windows
- Chimney balloons to stop heat escaping
These upgrades are inexpensive and relatively simple, but they can make a big difference in comfort.
Upgrade your heating controls
You may not need a brand-new boiler to improve efficiency, smarter controls may be enough for you to get more impact for less energy. Consider:
- Installing a programmable thermostat
- Using thermostatic radiator valves (TRVs)
- Zoning your heating to avoid heating unused rooms
Secondary glazing
Full double glazing can be expensive and may not suit period properties, especially in conservation areas. Secondary glazing can be either professionally installed or installed using DIY kits and offers a good alternative by reducing heat loss and noise without altering the look of your windows.
Use reliable traders for bigger jobs
If you decide that you need to invest in more significant work, such as cavity wall insulation or a boiler upgrade, make sure that you use a verified, reviewed professional so that you know that your money, and your home, are in safe hands.
Energy efficiency upgrades in older homes don’t have to be disruptive or expensive. Start small, focus on insulation and heating controls, and only bring in professionals when needed. Over time, you’ll notice lower energy bills, better comfort, and a smaller environmental footprint, all while keeping the charm of your older home intact.
