Decarbonised heating

New report: a green homes revolution could create 138,000 new jobs and inject £9.8bn into the economy

Decarbonised heating

A properly funded and ambitious programme to insulate homes and swap gas boilers for low-carbon heating sources, such as heat pumps, could deliver huge economic and social benefits, according to a Greenpeace UK report published today (21 Sept).

Up to 138,600 new jobs could be created and the economy boosted by £9.8bn by 2030 if the government were to deliver a strategy for decarbonising homes that significantly increased the deployment of heat pumps and energy efficiency measures, with grants to cover the costs.

These findings come ahead of the publication of the government’s Heat and Buildings Strategy and Spending Review, which are expected to set out plans for decarbonising homes and buildings, and the finances made available to do it next month.

Gov ‘missing a trick’

The report and analysis, produced by Cambridge Econometrics on behalf of Greenpeace UK, used macroeconomic modelling to assess the impact of three housing decarbonisation scenarios.

The central scenario, taken from the Climate Change Committee’s (CCC) central pathway for delivering net zero, aims to install just over one million heat pumps per year by 2030 and upgrade all buildings to EPC C standards within the next 10-15 years.

The other two scenarios were also based on the CCC’s pathway, but one used the government’s current, less ambitious plans to install just 600,000 heat pumps per year by 2028.

The other had the cost of heat pump installations rapidly falling to £5,500 in line with industry estimates.

‘The simple fact is, the government’s current plan to decarbonise homes won’t cut emissions enough to meet its own legally binding climate commitments or tackle the climate crisis. A more ambitious plan, which will sufficiently slash emissions from homes, could create many thousands of new jobs right across the country and pump billions into the economy. This should be music to the prime minister and chancellor’s ears.

‘Rishi Sunak will be shooting himself in the foot if he fails to deliver the required extra £12bn to green our homes next month. His reluctance to dig deep in order to tackle the climate crisis will cost the UK economy much more in the long run but he’d also be missing a trick when it comes to short-term economic growth. It’s time to stop tinkering around the edges and get on with tackling this crisis.’

Money and jobs

The analysis found that all three scenarios would provide a significant boost to the economy, both in terms of job creation and GDP. However, the greatest benefits would come from the more ambitious rollout of low-carbon heating technologies and energy efficiency.

The modelling showed the government’s current, less ambitious plans would add £3.9bn to the economy and provide 71,500 new jobs by 2030, whereas the scenario based on the CCC’s pathway, which sees significantly more heat pumps installed, would inject £4.8bn into the economy and create 84,700 new jobs by the same year.

The scenario in which heat pump installation costs are lower would boost the economy by £5bn but create slightly fewer new jobs at 83,400 by 2030.

In all three scenarios the analysis assumed that the government will provide £4,000 grants for households to install heat pumps over the first three years, with grants then falling over time to ensure the cost of installing a heat pump matched that of replacing a gas boiler.

It also assumed that the government will cover 45% of energy efficiency improvement costs.

Upgrades must be funded

The report also looked at alternative funding models. One of these, in which the government provides no extra investment and leaves all households to pay the full cost of upgrades and clean heating installations, delivered far less in terms of economic benefits.

GDP increased by just £0.2bn by 2030 and job creation was less than half of even the worst outcome under the partially funded scenario, with just 34,700 new jobs created. 

However, it shows that greening homes is a substantial net job creator, mostly in construction and manufacturing, even without government support. This is because money flows towards manufacturing and construction rather than utilities and fossil fuel extraction.

The final funding model saw the government fully fund the installation of heat pumps and energy efficiency measures across the UK’s housing stock. This provided the greatest economic gains by far. Such a scenario could provide a £9.8bn economic boost in 2030 and create almost 140,000 new jobs. 

While the range of scenarios and funding models all provided an economic benefit, it’s clear that the greater the government’s investment, the better the return, both in terms of jobs and economic growth.

Lower bills and better health

In addition to the economic and environmental benefits that a programme to sufficiently decarbonise housing would deliver, the report also highlighted a wide range of social benefits that would come from greening the UK’s homes.

They include lower bills, reduced fuel poverty and a reduction in health impacts related to cold homes, which currently cost the NHS up to £2bn a year. Savings to the NHS from warmer homes could be up to £848m annually.

‘This analysis highlights the substantial economic benefits that would result from a programme to encourage the deployment of heat pumps and energy efficiency measures into people’s homes. The government should take the opportunity presented by the Comprehensive Spending Review to set out a clear long-term framework for delivering these measures, which are an essential component in decarbonising the UK economy.’

There are concerns that the government’s Heat and Buildings Strategy and funding made available in next month’s Spending Review will fall short of what is required to tackle emissions from housing and fail to capitalise on the thousands of jobs that could be created and economic growth it could provide.

In order to maximise this significant economic opportunity Greenpeace UK is calling on the government to deliver within its Heat and Buildings Strategy a comprehensive package of grants, loans and tax incentives that would see the deployment of heat pumps rapidly ramped up this decade, covering the full cost for low-income households.

As well as a commitment to phasing out new gas boiler installations early in 2030s. This must be delivered alongside a fully-funded programme to properly insulate our homes.

Rishi Sunak must commit to an extra £12bn of public investment to green our homes in the upcoming Spending Review. Failure to deliver this level of investment, on top of existing commitments, will result in a missed opportunity economically, and result in the government failing to deliver the warm housing revolution that the UK desperately needs.
