Is this housing’s path to net-zero carbon emissions?
John Perry runs the rule over the government’s green housing plans
The prime minister’s 10-point plan for a green industrial revolution is aimed at achieving net-zero carbon emissions by 2050. In the housing sector alone, the challenge is enormous. Just to reach the government’s interim target for housing by 2035 means retrofitting 1.2 million UK homes every year. Will the government’s plan be up to the task?
In the Conservative election manifesto, £9.2bn was promised over five years for energy-efficiency work, beginning in 2020/21. But only part of this funding has been announced so far. The main programme is the £2bn allocated for the Green Homes Grant, of which £500m is available to local councils to help low-income households.
This was extended until March 2022 (and until December 2021 for the local authority element) but with no extra funding. However, there is also the promised new Social Housing Decarbonisation Fund which will, in the government’s words, “continue upgrading the least efficient social housing”. At first, just £50m of this was provided for “innovative approaches to retrofitting social housing at scale to make them greener”, although an extra £60m was announced in the Spending Review, with more promised for future years.
There are other initiatives that require private sector investment. The government wants to squeeze out the installation of gas boilers and achieve 600,000 heat pump installations per year by 2028. The Future Homes Standard will make new housing ‘zero-carbon ready’ and will ban gas boilers. Although a proposal to bring this forward to 2023 wasn’t included in Boris Johnson’s plan, The Times said it is still the firm intention.
The government is already consulting on tougher energy standards in the private rented sector and said it will consult on a mandatory requirement on lenders to declare the energy efficiency of homes when they are sold.

Put together, the green home finance initiatives are set to improve energy efficiency in 2.8 million homes, with 1.5 million reaching the interim target (an energy performance certificate band C) by 2030. Assuming this ambition relates only to England, it is still well short of achieving the 2035 interim target for the whole stock, so presumably will require more money for the Green Homes Grant as well as the promised social housing fund.
Whether the funding is adequate is at this stage only one of the obstacles to achieving the government’s targets. Already there are problems in delivering retrofits through the grant scheme. The Guardian recently reported that only 1,174 installers had signed up to the scheme while just 36,000 householders had applied for the grants. According to Bloomberg, only 267 grants have been paid so far.
“It makes sense to ensure existing homes can’t be let or easily sold if they are not energy efficient and that extra money is promised through the Energy Company Obligation scheme to help landlords comply”
Obviously the scheme’s extension will give them more chance, but the teething problems could have been avoided if the government had heeded warnings to plan earlier to train installers and increase the industry’s capacity. And because the scheme is voluntary, it seems likely to leave many houses falling short of band C and requiring further work later.
Replacing gas boilers with heat pumps is also a major task, involving a 20-fold increase in numbers installed annually. While capacity is also an issue here, other question marks apply to the quality of and consumer confidence in heat pumps and whether they will work properly in homes that are still not energy efficient.
This is why the green lobby has been advocating a ‘fabric-first’ approach which tackles insulation first and heating systems afterwards.
Bringing forward the Future Homes Standard is an excellent move. Although, as the Climate Change Committee pointed out, if this had been introduced when the Climate Change Act was passed, two million new homes would already have been built to higher standards. Instead these will now require expensive retrofits.
It also makes sense to ensure existing homes can’t be let or easily sold if they are not energy efficient and that extra money is promised through the Energy Company Obligation scheme to help landlords comply. The real risk here is that with turnover in the private sector of around one million tenancies annually, the inspection scheme won’t deliver and the standards could fall into disrepute.
So our judgement on the prime minister’s plan is that it’s a good start for the housing sector, but there is still a very long way to go. As Lord Deben, chair of the Climate Change Committee, put it: “This must now be turned into a detailed road map – so we all know what’s coming down the track in the years ahead.”
Judging from Inside Housing’s recent summary of the plans being made in the sector to achieve zero carbon, housing professionals who lead this field are in full agreement with Lord Deben.
