EPC Energy Performance Certificate Shock Surprise

AncientMariner

Our village halls attached house is due to be rented out again and a couple of days ago had a EPC Energy Performance Certificate survey.

Due its form of construction, its a late 1890s Grade II listed building, no cavity walls, no floor insulation etc I was pleased that it achieved a D rating which means that it is OK to rent out, since the current minimum is E for rented property. However I was a little nervous when the surveyor told me that from 2025 the minimum will be C but as a Grade II listed I should be able to get an exemption.

However, the house that my wife rents out scored a D in 2019 and in order to become a C requires, in the suggested order: Floor insulation, Solar Water heating and Photovoltaic panels with a typical expected cost of  £20,000 as per the certificate! I've ignored the sloping ceiling insulation which was Number 1 on the list at £1500, this due to the previous owner converting a utility room into a breakfast room and removing the ceiling and creating a pyramid style ceiling.

The certificate (like all others visible on the UK Gov website) reminds all that the UK average is D.  These rules apparently were from the EU and take into account that the average age of a house is higher in the UK compared with the EU, so theirs have been built on average to a better spec.

Interestingly electric central heating makes the situation worse, my wife's property luckily has had a condensing combi-boiler fitted 2 years ago.  I joked(?) with the surveyor whether an EV charger is good or bad, she was not too sure.

    I wouldn't worry too much, a lot of this green nonsense, the ban on gas boilers, compulsory heat pumps and electric cars etc will never happen, simply because we don't, and will not have enough generating capacity by the due dates. I reckon Boris is just blustering this nonsense in order to placate Carrie, the new Green Queen of No 10, in pursuit of marital harmony.

    They can hardly evict folk out of their houses simply on the strength of a poor energy performance rating.

     

    I disagree.

    There is no talk of banning gas boilers in EXISTING homes. The prohibition will on on installing gas boilers in NEW homes. New homes will be required to have good insulation such that very little heating will be needed. No heat pumps needed for new homes, resistance heating will be fine for the very small heating demand.

    Heat pumps could be applied to existing homes if desired.

    Electric cars use surprisingly little energy. A typical figure is about 3 or 4 miles per kwh. The average daily mileage is only about 30 miles a day. So an average charging demand of about 8 to 10 kwh a day. less than 500 watts average. Or about 1 kw overnight.

    No one is suggesting that tenants will be evicted from homes with a poor energy rating. The prohibition is on re-letting the property to a NEW tenant.

    Coincidentally, about the same as the average domestic usage, so in effect, doubling the household's consumption………………..

    Which would make the UKs consumption figures similar to what France has now - and interestingly they manage that with a typical domestic supply limited to 30A or 45A single-phase.

    I suspect that with off peak charging encouraged by preferential tariffs, that the existing generating capacity and distribution systems could cope with an average of a extra few hundred watts per house, overnight.

    Not everyone will get an EV so 1 kw per vehicle for overnight charging is nothing like 1kw per house.

    interestingly they manage that with a typical domestic supply limited to 30A or 45A single-phase.

    They don't want peaks when most of their generation is nuclear so limit domestic single-phase to 30 A (it may be 40 A now Andy) and if you want more, you have to have three-phase, still at 30 A per phase, but at a higher tariff. So, no 10.5 kW electric showers that the UK are so fond of and an intelligent CU supplying radial circuits to each socket-outlet so that appliance usage can be prioritised……………………………………
