Hot Air? EPC targets cannot be achieved with government funding

Savills estimates that £330 billion is needed to implement all energy efficiency improvements to the UK housing sector to meet EPC level C by 2035.

That's far more than provided through government funding - so Savills suggests more radical measures are needed.

The £330 billion figure is based on EPC certificate recommendations, covering interventions such as loft and cavity wall insulation, double glazing and replacing gas boilers, as well as small steps using low energy light bulbs and draught proofing.

The latest research which analyses EPC certificates to estimate the cost of implementing all advised energy efficiency improvements highlights the limitations of current grant schemes and the need for more radical intervention.

Between 2004 and 2017 CO2 emissions from residential property fell by 26 per cent but they have risen again by nine per cent between 2014 and 2020 according to government data. 

As a result, the UK’s residential housing sector was responsible for emitting 67.7 metric tonnes of carbon dioxide equivalent in 2020, which is over one-fifth of all UK CO2 emissions.

The vast majority - some 70 per cent - of this comes from heating properties, the bulk of the issue lies with older homes that present the greatest challenge. 

Around 30 per cent of homes in England and Wales built pre-war still carry an EPC rating of E or below, increasing to 47 per cent for those built pre-1900, according to Savills research.

The payback on many energy improvements remains unattractive, even if grant can be accessed to underwrite some of the cost. 

The estimated cost of upgrading a home with an EPC D rating is £6,472 – but with an average annual cost saving of £179, it will take 36 years to pay back the initial investment according to the English Housing Survey.

As a result, for the majority of homeowners, the impact that upgrading a home’s EPC rating will have on its value is limited.

At a national level, there’s just a £9,840 difference between an average home with an EPC C to E rating based on Savills analysis. Though this increases to £47,605 when comparing EPC B to F, the opportunities to make such a large change are far rarer.

Savills suggests that grants and green finance initiatives alone are unlikely to facilitate the step-change in investment in energy efficiency needed to meet government targets.

 

“Existing regulation provides a framework to require landlords to ensure their stock meets the increasing minimum standards for energy efficiency in the rented sector, however, it will place a significant liability on both private and affordable landlords that is likely to result in significant restructuring of their portfolios” says Lucian Cook, head of residential research at Savills.

“Decarbonising heating sources needs to go alongside improving the energy efficiency of our homes, but as things stand, energy cost savings and small changes to home values are currently not enough of an incentive for many homeowners who won’t see enough of a return on investment compared to other home improvements, to warrant the expenditure.

“With the government likely to impose EPC targets for lenders, the cost and terms on which mortgage finance can be obtained have the potential to change the equation for those with a mortgage. However, even this will not go far enough. 

“More than 10 million homes are owned outright – increasing by 1.6 million in just the past 10 years. These homes are typically older, less energy-efficient and change hands infrequently.

“This may mean discounts and surcharges on property-specific taxes such as stamp duty and council tax have to be considered by policymakers. These have the potential to increase the ‘green premium’ and ‘brown discount’ of housing, providing a greater incentive for owners to invest in energy efficiency improvements. However, they are likely to be highly politically sensitive, requiring, among other things, concessions for heritage properties.”

    Mankind contributes c 4% of co2 , 4% ! Of that China 28% , uk 1.1% , a minuscule amount in the grand scheme

    The whole climate scam is just that

    Most c02 is created by undersea volcanoes , the next biggest contributor is methane from animal's bottoms

    Same place most politicians speak from

    Truest thing I’ve read on here in ages…

    36 years, by then we’ll all be transhuman cyborgs 🤦‍♀️, the ones that are still alive that is…

    Very true. First time I have read anything that isnt a eulogy to climate change, (rebranded global warming !) WE have a complete idiot running the government and an opposition full of crap. Most insulation is derived from oil (can be coal) so its either burn it to keep warm or plasticise it as insulation. Most people seem to forget that you need ventilation to get rid of moisture and stale air and bring in fresh air to breathe.
    When are the Royal Family going to give up the queens flight ? They must have one helluva carbon footprint.

    Basically its about turnbing us into a peasant economy.

  • George Dawes

    That is definitely the long term plan , get rid of the middle class make everyone poor with no assets then control us completely. I’m glad I’m the age I am I just fear for the kids , what a bleak future

    I agree, I doubt it will affect me but our children and grandchildren have a very bleak future.
