Starmer to ban gas boilers and force developers to install heat pumps (2024)

Sir Keir Starmer's Labour government plans to ban gas boilers in most new homes by 2027, it has been reported.

The so-called 'Future Homes Standard' aims to cut carbon emissions across family homes - and will insist that developers make sure new-builds are kitted out with electric heat pumps or non-gas alternatives.

It has been suggested that the new rules could be brought forward for an announcement next May, although would not be enforced until the following year.

The expected measures come despite a bombshell report earlier this year revealing that the uptake of heat pumps to replace boilers had been lessthan half the expected levels.

The National Audit Office warned efforts to encourage homes to install the pumps have been slow with people reluctant to spend four times more than on a gas boiler.

Uncertainty over the role hydrogen could play in heating homes is also hampering investment, the report found.

The total installed in 2022 was just 55,000, well short of the Government's targets of 600,000 by 2028 and 1.6million by 2035.

The Financial Times has reported that the proposed ban on gas boilers in new homes would involve a 12-month delay to ensure housebuilders are prepared for the switchover.

The previous Conservative administration last year launched a consultation on the Future Homes Standard policy.

New legislation had been expected to be announced this month but has been put back by at least half a year following the general election last July, according to the Telegraph.

The plans form part of a mission to cut carbon emissions across all new homes by up to 80 per cent - but there have been concerns over whether enough new heat pumps can be supplied to meet targets.

Sir Keir's government has also pledged to build 300,000 new homes per year.

Steve Turner, executive director of the Home Builders Federation lobby group, said: 'We need to make sure the heat pump supply chain will be in place.

'At the minute, we're only installing about 35,000 a year – to go from there to up to 300,000 a year, plus additional ones fitted to existing homes, the supply chain will need a significant scale-up.'

He also raised fears over the capacity of the National Grid if put under extra pressure to serve heat pumps.

He said:'If you're not using gas for heating, that will load more on to the grid. We need to make sure there's enough resilience within that.'

It has previously been suggested that all new homes should be without boilers by the end of 2030.

Officials are also encouraging wider use of solar panels, although these are not expected to become mandatory.

A spokesman for the Department of Housing, Communities and Local Government said: 'We remain committed to delivering highly efficient new homes that will become net zero as the grid decarbonises.

'We are considering the responses to the Future Homes Standard consultation and will respond in due course.'

A study published last monthfound that British homeowners are being put off installing environmentally-friendly heat pumps by the high cost which has not reduced over the past decade.

Researchers said the systems only play a 'marginal role' in heating UK homes - and installation numbers remain low compared to traditional, fossil fuel-based systems.

An average air source heat pump costs about £10,000 while a ground source one is £20,000, the academics estimated - figures which have hardly changed since 2010.

The analysis by the University of Edinburgh and Imperial College London said the high costs meant ambitious Government targets for installations would be missed.

Projections suggest a fall of 20 to 25 per cent in installation costs by 2030, but the study said this also 'falls significantly short of the targets' set by the Government.

The experts said it costs an average of £3,000 to install a traditional gas boiler – 30 per cent of the average price of air source pumps and 15 per cent of ground source.

Ignoring any available Government grants or loans, achieving cost parity with air source heat pumps would therefore require a 70 per cent drop in installation costs.

The Government's Boiler Upgrade Scheme offers grants of £7,500 towards a heat pump - a greener alternative to a gas boiler which takes heat from outside and pumps it back into buildings to warm them up.

The study concluded that Government policies should be based on 'realistic assessments of likely cost reductions', and 'develop incentives that can address the relatively high upfront costs of some low carbon technologies'.

Heat pumps run on electricity and capture heat from outside before transferring it inside

Advocates of heat pumps say they offer energy security and efficiency benefits and can also lower energy bills.

But homeowners who have installed the systems have complained that their monthly bills skyrocketed during the energy crisis.

A report by innovation charity Nesta in July found one in 10 households – around three million homes – need to install heat pumps or other low carbon heating during this parliament to meet climate targets.

It also revealed that the UK installed only an estimated 250,000 heat pumps between 2020 and 2024, while 25.5million homes still use oil or gas boilers.

What are heat pumps and what do they cost?

AIR SOURCE HEAT PUMPS

Average cost: £10,000

Air source heat pumps absorb heat from the outside air at low temperature into a fluid to heat your house and hot water. They can still extract heat when it is as cold as -15C (5F), with the fluid passing through a compressor which warms it up and transfers it into a heating circuit.

They extract renewable heat from the environment, meaning the heat output is greater than the electricity input – and they are therefore seen as energy efficient.

There are two types, which are air-to-water and air-to-air, and installing a system costs up to £8,900 once the £7,500 Boiler Upgrade Scheme grant has applied. But it can also be significantly less, depending on the size of your home and its insulation.

GROUND SOURCE HEAT PUMPS

Average cost: £20,000

Ground source heat pumps use pipes buried in the garden to extract heat from the ground, which can then heat radiators, warm air heating systems and hot water.

They circulate a mixture of water and antifreeze around a ground loop pipe. Heat from the ground is absorbed into the fluid and then passes through a heat exchanger.

Installation costs between £15,000 to £30,000 depending on the length of the loop, and running costs will depend on the size of the home and its insulation. The £7,500 grant will lower the price on the installation.

The systems normally come with a two or three year warranty - and work for at least 20 years, with a professional check every three to five years.
