EPC Herts has compiled some valuable tips to help you improve your energy performance certificate (EPC) rating. It’s advisable to review this guidance before your domestic energy assessment takes place at your property.
To enhance your EPC rating, ensure that as many of your fixed light fittings as possible are equipped with low energy lamps. This small adjustment can make a noticeable difference.
If your home includes a hot water tank, it’s crucial to have ample insulation around it, as effective insulation can significantly improve your EPC rating.
Regarding loft insulation, if access to the loft is restricted or if it’s boarded over, I may have to report the insulation status as 'unknown'. This could negatively impact your EPC rating. Please have any documentation available to demonstrate the loft insulation is present.
Cavity wall insulation is another important factor that can greatly affect your EPC rating. If your insulation is not visible due to external rendering, it may result in a lower EPC rating since we have to assume that no insulation is present. Ensure you bring along paperwork to confirm that your cavity walls have been insulated.
For double glazed windows installed after 2002, it's beneficial to provide documentation that verifies the installation date. This can positively influence your energy performance certificate.
In terms of boiler information, I will attempt to ascertain the exact make and model of your gas or oil heating boiler. If achievable, knowing the precise efficiency of the boiler can yield a higher EPC score compared to the software's default setting for that boiler type. Since visually inspecting boiler details can be challenging, please have any manuals or service history available for reference.
