Surely I am not the only landlord worried about new EPC requirements?

Your correspondents have hi-lighted the major flaw in the current domestic dwelling Energy Performance algorithm (the software program calculating EP scores).
The EP algorithm was born as a part of the ill-fated Home Information Pack in 2004, in the days when we weren’t so concerned about global warming. The algorithm/methodology has changed little since then.
At the time, energy units (kWh) supplied by gas and by Economy-7 night-time electricity were much cheaper than a regular (all-day) units – and they still are – which meant that a consumer who heated a home by these means could afford (literally afford) to be more wasteful of energy. So the EP algorithm was deliberately fiddled to award far more points for gas heaters and night-time storage heaters than was justified, yielding higher EP Classifications in those cases than they actually merited.
Of course this built-in fiddle in the algorithm made a complete nonsense of an EP rating supposedly making an objective assessment of the intrinsic energy performance of a domestic dwelling.
The number of all-electric homes will increase vastly as domestic use of natural gas is phased out – let’s remember that after 2024/5 there will be NO methane gas supplied to new-builds and unrepairable combi-condenser boilers will have to be replaced by electric boilers – and the long-overdue revision of the EP algorithm will have to happen before then. (In my professional opinion, replacing piped methane with piped hydrogen is a completely uneconomic non-starter – forget it.)
The climate in 2021 onwards will continue to warm. It doesn’t distinguish between a kWh energy unit from heating with gas and one from heating with electricity!! All kWh energy units are equal to climate warming, regardless of the source, and should be treated as such for EP calculation purposes. Some are NOT “more equal than others”, and never have been, even if the EP algorithm then – and still – believes that they are.

NRLA call for extension to safety certificates

Dear Jan
EPCs expire after 10 years, unless I am very much mistaken. So after 9 years 10 months (March 2020 in my case) you need to get an EPC surveyor to visit and issue a new one (valid for the next 10 years).... Read More

NRLA call for extension to safety certificates

And what about Energy Performance Certificates (EPCs)? I'm stuck in the same position. An EPC runs out in June - my usual EPC surveyor has cancelled the appointment made for May. If I can't get another EPC surveyor to come then I will become "illegal".
So a 6 month extension to renew EPCs is required just as urgently as for Gas and Electricity certificates.... Read More
