Understanding how to make small improvements to your home before an EPC assessment will help increase your energy
Improving Energy Efficiency in your home?
Once an appointment has been made for your EPC assessment you may have time to improve
your property’s energy efficiency before the assessment is made. Below are low-cost improvements, typically
those under £500, that could improve your energy rating.
A low energy bulb is an easy improvement to make and one that can mean real savings on your
electricity bill. A low energy bulb produces light for 80% less energy than a normal bulb. Having
low energy bulbs in 75% of your fixed fittings will receive a very good rating on your EPC. They
are compact fluorescent bulbs that can last up to 10 000 hours. Low energy bulbs can still be
fitted in downlights, but those fitted in removable lamps will not be counted.
Improving your loft insulation to the current building regulations of 270mm will have a
significant effect on your EPC rating. If there is less than 150mm insulation in your loft space the
EPC will recommend increasing it to 250mm. Loft insulation can be fitted by any able-bodied
person and to save time the insulation can be laid over joists.
Hot water cylinder insulation
If your property has a hot water cylinder it should be adequately insulated. The EPC will
recommend fitting an additional jacket even if your cylinder already has factory applied foam
insulation. Check your cylinder, if it has factory applied spray foam of less than 25mm, fit an
additional jacket. If your cylinder already has a jacket but it is less than 80mm fit an additional
jacket to increase the total width to 80mm. Fitting insulation to an uninsulated cylinder will
significantly improve your EPC rating. Fitting a cylinder thermostat to a cylinder in a gas central
heating system is also an EPC recommendation.
Improving energy efficiency within your home is a great way to increase your EPC score as well as to save you money.
There are those measures such as cavity wall insulation and improved heating controls such as
programmers, room thermostats and thermostatic radiator valves that will dramatically improve
your EPC rating. However, these measures are more costly and will need to be carried out by a
