  • Are Gas Boilers Being Phased Out in the UK?

Updated: October 14, 2024

There has been ongoing discussion about the future of gas boilers in the UK, with growing concerns about their environmental impact. The UK government has set ambitious targets to reach net-zero emissions by 2050, leading to proposals to phase out gas boilers in favor of cleaner, low-carbon alternatives. In this article, we will examine the current situation regarding gas boilers, what the phase-out means for homeowners, and what the heating solutions of the future might look like.


Are Gas Boilers Being Phased Out?

The simple answer is yes—but not immediately, and not entirely across the board. The UK government is working towards reducing carbon emissions by phasing out gas boilers gradually, starting with new-build homes.

Key Points:

  • 2025 Ban on New Builds: From 2025 onwards, newly built homes in the UK will no longer be fitted with gas or oil boilers. These properties will instead be equipped with low-carbon heating systems, such as heat pumps.
  • No Ban on Existing Boilers: For homeowners with existing gas boilers, there is no mandate to remove or replace them. However, over time, when these boilers reach the end of their lifespan, they will need to be replaced with a more sustainable alternative.
  • Phase-out by 2035: The government has set a target to phase out the installation of new gas boilers in all homes by 2035. While this date is not set in stone, it reflects the UK’s push towards more eco-friendly heating solutions.

Although these deadlines seem distant, they signal a clear direction: the future of domestic heating is shifting away from gas. However, homeowners can continue using their gas boilers until they need replacement, and no immediate action is required unless upgrading voluntarily.

Domestic Heating Systems of the Future

With gas boilers on the way out, what are the alternatives? Several low-carbon heating systems are being developed and promoted to meet future heating needs. Below are the most likely contenders to replace traditional gas boilers.

1. Heat Pumps

Heat pumps, both air source and ground source, are considered one of the most promising replacements for gas boilers. These systems extract heat from the air or ground and convert it into energy to heat your home.

  • Air Source Heat Pumps (ASHP): These work by drawing in outside air, even in cold temperatures, and transferring the heat indoors. ASHPs cost between £8,000 and £15,000 to install, although they can be expensive upfront, they are highly efficient and reduce long-term heating costs.
  • Ground Source Heat Pumps (GSHP): These systems are even more efficient, using the stable temperature of the ground to heat your home. However, they are more costly, with installation prices ranging from £18,000 to £25,000. The upfront costs can be reduced through the government’s Boiler Upgrade Scheme (BUS), which offers grants of £5,000 to £6,000 for heat pump installations.

2. Electric Boilers

Electric boilers are gaining popularity as a gas-free alternative, offering an eco-friendly solution when powered by renewable energy. They function much like gas boilers but use electricity to heat water.

  • Cost: Installing an electric boiler typically costs between £1,000 and £2,500, making it more affordable than some of the other low-carbon options. However, it’s important to ensure the electricity comes from a renewable source to truly minimize carbon emissions.

3. Hydrogen Boilers

Hydrogen boilers are another option for the future of home heating. These are similar to gas boilers but use hydrogen, a clean fuel, instead of natural gas.

  • Hydrogen-Ready Boilers: Manufacturers are already producing hydrogen-ready boilers that can run on both natural gas and hydrogen. As hydrogen technology becomes more widespread, these boilers will offer a seamless transition for homeowners looking to reduce their carbon footprint.

Hydrogen boilers could play a key role in the future, as hydrogen fuel is more environmentally friendly than fossil fuels. However, large-scale adoption of hydrogen as a fuel is still in its early stages, and it may take time for hydrogen boilers to become mainstream.

4. Biomass Boilers

Biomass boilers use organic materials, such as wood pellets or logs, to generate heat. While these systems are environmentally friendly, they are typically used in larger homes or commercial properties.

  • Cost: Installing a biomass boiler typically costs between £4,000 and £10,000. Although they are eco-friendly, the high installation cost and need for regular fuel deliveries make them less practical for the average household.

What Does the Future Hold for Gas Boilers?

The phase-out of gas boilers will be gradual. There is no need to worry about an immediate ban, and homeowners can continue using their existing systems. However, there are a few important things to keep in mind:

  1. Government Incentives: The Boiler Upgrade Scheme and other government initiatives aim to encourage homeowners to switch to renewable energy systems. Financial assistance is available to help reduce the upfront costs of installing heat pumps and other low-carbon technologies.
  2. Gradual Transition: Homeowners will not be forced to replace their gas boilers overnight. The phase-out will occur over decades, allowing time for households to transition to new technologies when they are ready.
  3. Energy Efficiency: Modern alternatives like heat pumps and electric boilers are more energy-efficient than gas boilers, reducing energy consumption and long-term costs.

FAQs About the Gas Boiler Phase-Out

1. Will I Have to Remove My Existing Gas Boiler?

No, there are no plans to force homeowners to remove existing gas boilers. You can continue using your current boiler until it needs to be replaced.

2. What Is the Most Likely Replacement for Gas Boilers?

Heat pumps, particularly air-source heat pumps, are expected to become the most common replacement for gas boilers. They are energy-efficient and well-suited for UK homes.

3. How Long Do Gas Boilers Typically Last?

A well-maintained gas boiler can last between 10 and 15 years. As your boiler ages, it may become less efficient, so replacing it with a more eco-friendly option may be beneficial in the long run.

4. Can I Get Financial Help to Replace My Gas Boiler?

Yes, the Boiler Upgrade Scheme offers grants to help cover the cost of installing low-carbon heating systems, such as heat pumps.


Final Thoughts

The future of home heating in the UK is moving away from gas boilers towards more sustainable, low-carbon solutions. While gas boilers will not be banned outright anytime soon, new regulations will encourage homeowners to switch to cleaner alternatives over the next few decades. Heat pumps, electric boilers, and hydrogen-ready boilers are leading the way as the primary candidates for replacing gas central heating.

Now is the perfect time to explore your options, whether you want to stay ahead of the curve or simply want a more energy-efficient heating system. Government grants and incentives can help offset the costs of upgrading to greener technologies, ensuring a smooth transition for UK households as they move toward a more sustainable future.
