Before paying for expensive upgrades, it makes sense to find the easy wins. A DIY home energy audit helps you spot the gaps in insulation, heating habits, and appliance use that quietly push your bills up every month.
Check insulation and draughts first
Start with the basics. Loft insulation below 270mm, gaps around doors, and poorly sealed loft hatches are all common money leaks in UK homes. A cold, windy day is perfect for checking where air is getting in and warm air is escaping.
- •Measure loft insulation depth if you can safely access it
- •Feel for draughts around doors, windows, skirting boards, and letterboxes
- •Use low-cost draught excluders and foam strips where needed
- •Check whether radiators are blocked by furniture or curtains
Review heating controls and habits
Many households waste energy not because the boiler is terrible, but because the controls are badly set up. Lowering the thermostat by 1°C, using timers properly, and bleeding radiators can make a noticeable difference with almost no cost.
- •Use a timer so heating matches when people are actually home
- •Lower the thermostat by 1°C if comfortable
- •Bleed radiators once or twice a year
- •Fit TRVs where possible so unused rooms are not overheated
Audit appliances and standby use
Appliances often create a slow drip of unnecessary spending. Older fridges, always-on tumble dryers, and televisions left on standby all add up. A simple socket energy monitor can reveal which items are worth changing first.
- •Check old appliances for efficiency and usage time
- •Line-dry clothes when possible instead of using the tumble dryer
- •Turn off clusters of electronics at the wall overnight
- •Use LED bulbs throughout the home
Is a professional energy audit worth it?+
It can be, especially for older or larger homes where insulation or heating upgrades may cost thousands. But for most households, a DIY audit is enough to identify the cheapest first steps.
How much can a DIY audit save?+
The exact figure varies, but many households can find £200–£500 a year in combined savings by tackling draughts, heating habits, lighting, and inefficient appliance use.
