An ‘indicative’ cost is shown for recommendations on my EPC - what does this mean?

The indicative cost of recommendations are those that apply to a typical property. They may differ for very small or very large properties or ones with special features.

The costs shown on the EPC are higher than my actual energy bills for the year, why is this?

EPCs use standardised assumptions so as to make properties directly comparable while still reflecting the features of individual properties. The EPC costs are based on a number of assumptions: a standardised heating pattern, number of occupants, hot water usage, etc. These factors vary appreciably between different households even if living in similar properties.

Why are the potential heating costs greater than the current heating costs when the EPC recommends low energy lighting is installed?

This occurs when low energy lights are recommended and there is no recommendation for improvements to the heating system (usually because an efficient system is already installed). Standard light bulbs generate more heat than low energy light bulbs; by replacing standard bulbs with low energy bulbs the heat generated by the lighting is reduced and the heating system has to make up the difference. The reduction in the lighting cost is appreciably greater than the increase in the heating cost, so there is a net reduction in energy costs for the property.

Your boiler accounts for up to 70% of what you spend on energy every year. This means replacing your old, inefficient boiler for a modern ‘A’ rated boiler can save up to £490 per year on running costs!

Around a third of all heat lost in a solid wall or non-traditional property is lost through the walls. In such properties cavity wall insulation is not possible so externally insulating is often the best option.

There has never been a better time for homeowners to invest in renewable energy and in particular Solar PV. Not only do homeowners benefit from free, self-generated electricity but any surplus is sold back to the National grid and you get paid for it via the Feed-in Tariff.
