Het kost ongeveer £6,155 om een huis van een energieprestatiecertificaat (EPC) classificatie van D naar een C te upgraden.
Habito's analyse toonde aan dat hetuity zal kosten ongeveer £3,653 om een studio van EPC D naar C te upgraden, terwijl een kleine tussenwoning in een rijtjeshuis waarschijnlijk tot £6,400 zal kosten.
Grote vrijstaande huizen zullen naar verwachting ongeveer £12,540 kosten in energiebesparende verbeteringen, wat meer dan het dubbele is van het nationale gemiddelde.
Er zijn momenteel geen wettelijke vereisten voor huiseigenaren in het VK om een minimale EPC-classificatie te behalen.
Als je, zoals de meeste panden in het VK, een EPC-classificatie van D hebt, dan kun je je classificatie relatief gemakkelijk tot C verhogen.

The research shows how much it would cost to raise a D-grade EPC to a C. According to the findings, it will cost roughly £3,653 for a one-bedroom flat to achieve this rating. A small terrace house is likely to cost up to £6,400 to go from a D to a C, while £12,540 worth of energy-saving improvements is said to get larger detached homes from a D to a C grade. Window replacements can improve an EPC score by up to 10 points. These range between £100 to £1,230. Loft insulation can add 30 points to an EPC rating, which is guaranteed to make a significant difference. Checkatrade estimate this upgrade costs £250 for labour alone. Switching to a newer model of boiler can increase the EPC rating up to 40 points. Costs range between £600 to £2,500 for a replacement boiler. Solar panels can add up to 15 points to EPC ratings. These are by no means cheap as Energy Saving Trust’s figures claim a 4.2 kilowatt-peak solar panel system is about £6,500.

The cost of upgrading a property from an energy performance certificate rating of D to C is up to £6,155.
It calculates that for one-bedroom flats or properties measuring under 55m² the cost is up to £3,653.
For a small mid-terrace house it is up to £6,400.
For a large family detached home the potential cost rises to £12,540.
But with 59% of homes registering a D rating or below, this could amount to £38bn nationally.

It is only when upgrading from an E, F or G to a C will a landlord face such high costs.
I’ve been in this sector for 15 years and my experience tells me that it will cost most landlords substantially less to upgrade their properties to an EPC band C from a band D.
From my experience of helping landlords improve their EPC to a C the expense of improving from D to C is substantially less than £5,000, although of course every property is different.
There are a number of inexpensive and simple measures a landlord can take such as new LED eco-bulbs costing a few pounds and adding TRV radiator valves - if the property does not have them - for example would improve the EPC at least one point for each measure.
An average property in the UK has an EPC of D with an EPC score of 60, so upgrading from 60 points to a C (minimum 69 points) is a nine-point increase, and usually that doesn’t require expensive work.

5 percent can expect to spend: less than £1000
25 percent can expect to spend: £1000 to £4,999
46 percent can expect to spend: £5000 to £9,999
20 percent can expect to spend: £10,000 to £14,999
4 percent can expect to spend: £15,000 or more
While the most likely outcome for landlords is a ballpark price tag of £7,500.
