But will you be forced to replace your existing boiler, and how much will it cost you? Telegraph Money takes a look.
When does the gas boiler ban come in?
The Government announced that by 2025 newly-built homes cannot have gas boilers installed, and must instead be heated using low-carbon alternatives. This ban will not apply to new boilers fitted in existing homes.
However, in a hydrogen strategy unveiled last month, officials said the Government would also explore “enabling or requiring” new natural gas boilers to be “easily convertible to use hydrogen” by 2026. This could apply to new boilers fitted in existing homes.
The Government’s climate change advisers have also recommended a ban on sales of conventional gas-only boilers by 2033. Around 1.7 million of these devices are replaced in Britain every year.
What are the alternatives to gas boilers?
As a total ban on the sale of gas-only boilers is not expected until the mid-2030s, a device fitted today would likely last most of its typical 15-year lifespan before it would need to be replaced with a low-carbon alternative.
Even when the ban does come in, it would only apply to new installations, and as of yet there has been no suggestion working gas boilers would need to be replaced.
Installing low-carbon heating today would cost more than a gas boiler, though costs will likely come down considerably before any ban.
The Government’s advisers previously said hydrogen will only be suitable in around 11pc of homes, meaning some “hydrogen-ready” boilers could be installed but continue to run on gas.
Meanwhile, heat pumps have also been explored as an alternative. The Government wants 600,000 of these devices installed in homes each year by 2028.
There are two types of heat pumps currently available. Air source heat pumps pull ambient heat from the air and increase the temperature using a compressor. This is then used to heat radiators and water. Ground source heat pumps are similar but draw heat from pipes buried in the ground. These have higher up-front costs but run more efficiently.
Questions have been raised over both the cost of the devices and their effectiveness in heating homes when compared to traditional boilers.
Heat pumps are usually powered by electricity, which is much more expensive than gas or oil, but they are three to four times more efficient than traditional boilers. This means running costs are similar, according to the Energy Saving Trust.
The Energy Savings Trust said a standard air source heat pump installed in an average-sized, four-bedroom detached house would be between £395 and £425 cheaper to run a year than an old “G-rated” gas boiler.
It could be between £500 and £550 cheaper than a G-rated oil boiler or up to £1,300 cheaper a year to run than a G-rated LPG boiler. Newer gas and oil boilers are cheaper to run, however, so the savings would be smaller.
Can I get paid to switch?
A Censuswide survey for the RSK Group, the services provider, found that eight in 10 people would be willing to change how their home is heated to reduce the impact on the environment. However, when asked how much they thought a heat pump system might cost, the average estimate was £3,290.
While a replacement gas boiler can cost around £1,000, an air source heat pump full system installation can cost between £7,000 and £14,000, with ground source heat pumps costing between £15,000 and £35,000.
More than half of respondents to the Censuswide survey said the high upfront cost was the most likely reason to persuade them not to install a heat pump. As a result, eight in 10 respondents said they would only install a heat pump system if they received financial support from the Government.
Those who said they would need a grant to persuade them to install a heat pump would, on average, want a grant to cover 46pc of the cost.
People who join the scheme and abide by its rules receive quarterly payments for seven years, based on the amount of renewable heat that their system has produced. This can help offset some of the costs of installing an air source heat pump, but does not match the 46pc grant that people expect on average.
Some energy firms, such as Igloo Energy, offer schemes that help meet the upfront costs of fitting a heat pump in exchange for the quarterly subsidies.
The Government is launching Clean Heat Grants from April next year, which will replace the Renewable Heat Incentive and last for two years. It will offer grants of up to £4,000 to help install devices such as heat pumps.
