Britain’s new climate plan that could make millions of homes unsellable

December 31, 2020

By Paul Homewood




Last week, the government’s Climate Change Committee published its ‘Sixth Carbon Budget’ recommending what it thinks the government needs to do in order to meet its target of achieving net zero carbon emissions by 2050. Much comment revolved around the proposed ban on new gas boilers from 2033, after which homes would have to be heated either by electric heat pump or possibly by hydrogen boilers, should the government decide to repurpose the existing gas distribution network for hydrogen.

But there is a far bigger nasty concealed in the document that was hardly reported:  a proposal that the sale of properties be banned from 2028 unless they score at least a grade C in an energy performance certificate (EPC).

This has serious implications because millions of British homes will not reach this level and cannot be brought up to this standard at any reasonable cost. I have serious doubts as to whether an EPC energy grade means anything, given that it is just a crude estimate of how well an computer algorithm thinks it ought to perform, not a test of how it performs in practice.

Moreover, these reports seem highly sensitive to who is carrying them out – I hade two done on my home in the space of a year, one of which gave me a score of 42 out of 100 and the second, after I had replaced some windows with better-insulated ones, gave me a score of 32. The report informed me that even if I undertook all the recommendations in the EPC, which consisted of fitting solar panels and replacing the boiler, it was only going to bring me up to a score of 49 – a grade E.

In other words, I could spend over £10,000 and still I wouldn’t be allowed to sell my house and nobody would be allowed to buy it. Not only that, the Climate Change Committee recommends that mortgages shouldn’t be allowed on homes with a EPC rating of less than ‘C’ by 2033. So you, you won’t be able to sell, or to have a mortgage on your home. What are you supposed to do then?

There are nine million homes in Britain which, like mine, have solid walls. It is going to be virtually impossible to bring many of them up to a ‘C’ rating unless their walls are insulated. You can do that ‘cheaply’ by stick insulation on the inside or outside, but even so that will cost – in the case of a three bedroom home – between £7000 and £13,000, according to Which. But it is fraught with problems.    If your house wasn’t built with a damp proof course – which applies to just about any house built before the 1920s – you could be trapping in damp. More realistically, to achieve a grade ‘C’ rating you would have to undertake a complete refurbishment, stripping the property back to the bricks and starting again. For millions of homeowners, that is not an option.

Has the Climate Change Committee thought for the moment of the repercussions of its recommended policy: to make millions of homes unsaleable? These unsaleable properties would be in addition, of course, to the many thousands of recently-built homes which, although they notionally have excellent energy performance, are unsaleable thanks to flammable cladding and insulation.

    To all intents and purposes its 2025 for rented properties, ie all new or renewed ASTs after this date.
    As the BoE has based its entire monetary policies on keeping the housing markets bouyant as the commercial banks would fail if it wasn’t, it will be interesting how this plays out, given the new CC requirements on the Bank. Something will have to give, and I doubt it will be the BoE.

    How would the air source heat pumps be working today with temperature below freezing and a shortage of wind, which is now providing under 4 GW, with a demand of almost 40 GW.
    I am also intrigued to know what the performance of Evs is panning out with lights, heaters and range, especially as lithium batteries apparently don’t work too well at low temperatures

    Everything about decarbonisation policy is bad in varying degrees but it is also completely unnecessary for the UK at least, since our output of greenhouse gases is negligible.
    So even were the almost certainly mythical CO2-climate disimprovement causal relationship in any way relevant to the Earth and its people’s, no harm would be done by ending these policies and despatching the CCActs and CCCommittee to oblivion, with gags on the members and no pockets to stash away the gains from corruption.

    Before Prof Kelly’s reports were published I did a little exercise on my own, modest, three bedroom, Victorian Alms cottage to see just how much it would cost to install a Ground Source Heat Pump (GSHP), appropriate radiators, solid wall insulation, double glazing, and a whole house ventilation system (essential if you seal a house up).

    The whole lot came to around £100,000. Consistent with Prof Kelly’s estimates, and around the £3Tn mark he calculates to convert every house in the UK.

    I don’t know about anyone else but I don’t have a spare £100k lying around so, like most people I would be forced to borrow from…….The Banks.

    £3Tn of business for them would be very welcome, I’m sure.

    • December 31, 2020 6:20 pm

      To borrow £100,000 over ten years would cost me about £1,000 per month.

      My pension is about £950 per month.

      So how would that work?!

      Your local authority will provide you with an interest free loan for life to do the work, and your property will become theirs when you die. If you refuse, they will declare your property uninhabitable (as they already can for other reasons) and subsequently seize it as a blight on the area (as they can already do for other reasons).

      You think I’m joking……..?

    Further thoughts. At the moment people are going along with CC as they don’t see themselves being affected much, electric cars, you still have a car, no gas cookers, well you still have a cooker etc.etc. but there comes a point when the general public will realise that their comfy life is about to be severely disrupted and this might be it. The key to it is of course that they have to have spelt out to them. Will that happen……..maybe.

    The suggestion that the government has a right to prevent two parties from transferring a property from one to another is against human rights as we know it.
    On the subject of CO2, The world is definitely greening up as most people will realise just by looking around them. Is there perhaps a relentless absorption of any CO2 rise and the higher levels we may see in the atmosphere are simply gases ‘in transit’ ?

    Seems you Brits are having a personality problem.
    You spent 4 years extracting the Nation from the bureaucratic union and regain your sovereignty. Congratulations for that!
    Meanwhile, the climate cult has twisted the Nation into knots.
    This stuff about housing being just the latest nonsense.

    It occurred to me that your “betters” have classified the people as “emeriti” – in the old sense of a no-longer useful Roman solider – a bit of a burden to the rulers, so please die soon.

    Nevertheless – – 2021 is here.
    – May the road rise up to meet you.
    – May the wind be always at your back.
    – May the sun shine warm upon your face;
    . . . the rains fall soft upon your fields

    From the report, in respect of achieving EPC band C:

    Page 120: “Total investment costs are less than £10,000 per household on average in our Balanced Pathway. 63% of homes need spend no more than £1000 on retrofitting energy efficiency measures.”

    A simple calculation; if average = £10,000 and 63% = £1000 then 37% = £25,324.
    Extrapolating from this, 20% of homes will need to spend £55,000 and 10% £77,500

    Then in Table 5.1 on page 247, they give the average cost for a heat pump in 2020 of £6,415, for a pump rated at 5.4kW.

    This may be useful in a small flat but the average house will need more like 8-9kW at a cost of £10,000+

    The CCC are displaying as much honesty with energy figures as Volkswagen did with NOx emissions, the difference being that homeowners will not be able to sue the CCC for deliberately fiddling the figures.

      There’s no mention of the disruption or additional costs. e.g. to insulate walls internally would require most kitchens to be dismantled – and kitchen cabinets are not designed to be refitted. So add in the cost of a new kitchen.

      Internal insulation would also mean complete redecoration of every external wall and window and door surrounds would need to be altered. The potential for damp behind the internal insulation is immense.

      The issues involved with external cladding are at least as challenging. Much of the UK’s housing stock is Victorian red brick or sandstone. The character of these houses will be drastically altered. The wholesale alteration of entire rows of these houses would need to be co-ordinated somehow, which means planning consent. The problem is, planning departments have all been hollowed out thanks to ‘austerity’ of the last ten years or so. The workload and cost would be immense.

      Unless every house is to be turned into a sauna and running with damp, they will need some sort of whole house ventilation. To do it on the cheap would need, at least, quality heat exchanger units in each room which is getting on for several hundred quid per unit, not including the fitting and wiring. Then there’s the cost of running the units, maintaining them etc.

      Clearly, no one in government has spoken to a builder about this.

      VW were trying to give their customers vehicles that worked well for them since what they did to pass the tests did not make their cars worse for drivers to use. For years motorcycle manufacturers had been engineering flat spots in the power curves of their engines at the revs required by the noise tests. Hardly beneficial to the riders and because riders are a more proactive lot, many would get the flat spot tuned out given that the noise test would never be repeated. How much easier with ECUs and injection systems it is to do that and make it easy to change.

    Although I’ve mentioned this before on NALOPKT, I think it’s worth mentioning again as it illustrates the reality of the CCC’s mindset.

    About three few weeks ago, I had an interesting exchange with Piers Forster – Professor of Physical Climate Change at Leeds U and a member of the Committee on Climate Change. I asked him this:

    Do you agree that, unless all countries that are a major source of emissions (e.g. China, Russia and India) are fully committed by at least this time next year to substantial and urgent emission cuts (as required by the UNEP Emissions Gap Report 2020), there’s no point in the UK (the source of less than 1% of emissions) proceeding with its expensive and potentially damaging net-zero ambition – particularly as we’ll be struggling at the same time with Covid’s aftermath and difficult Brexit problems?

    He answered by saying that ‘even if we were the only country decarbonising it would be worth it.
