The recommendations table is so important because it breaks down how much your EPC rating can be improved, what the costs to make the improvements are and as a result, how much of a saving you can make on your annual energy bill. This will help you to make an informed decision on what changes you should be making.
The lower the rating on the certificate, the more attention you should give to the recommendations section as this could make a significant difference to the value of a property.
The recommendations in the table are made in cumulative order, this means that in the table, the potential improvement rating shown in the right column is only applicable if all the improvements up to and including that row are made.
You’re not legally obligated to make changes recommended.
The G rated property has nine recommendations that could take the property from a G11 rating to a C76 – a huge increase of 65 points. But, to achieve this would be a cost of up to £51,640 to result in energy savings of £2,910 per year (payback of 18 years). Cost effective?
To take the property to an E rating and an increase of 38 points would be a cost of up to £12,640 resulting in energy savings of £1,870 (payback of 7 years). A more reasonable achievement and would take the property to the minimum rental rating.
The A rated property has one recommendation of solar water heating. At a cost of up to £6,000 this will only make savings of £51 and an improvement of one point to A96 on your EPC. Probably not an investment worth making.
