Proposals to ban gas boilers after 2025 in new build homes can be confusing to understand. Read on and we’ll give you the inside line on what will replace gas boilers after 2025.

What are the plans for phasing out gas boilers?

First of all, it’s important to be aware that, right now, the proposals to phase out gas boilers are just that - proposals. And even then, the proposal only covers new build properties, not existing homes.

While changing to more efficient and environmentally friendly heating systems will be core to achieving net zero by 2050, such a rapid change across the board cannot be implemented so easily.

Are gas boilers being phased out in 2025?

In short, no. The government’s proposed legislation only covers new build homes that are constructed after 2025, meaning that such properties will be heated using alternative sources, such as heat pumps.

You will still be able to buy A-rated gas boilers and have them installed in existing homes after 2025.

Will gas boilers be banned from 2025?

No, gas boilers will not be banned from 2025. In the future, it is likely that gas boilers will be phased out in order to facilitate the transition to net zero. But that will only happen when alternatives are much cheaper and infrastructure has been improved to such a degree that we do not need to rely on gas to heat our homes and hot water.

A rated, fuel efficient gas boilers will still be on sale after 2025 and will offer a cost effective option for those looking to replace an ageing heating system.

Do I need to replace my gas boiler?

It may be a good idea to replace your gas boiler if it is more than 15 years old. The good news is that getting a new boiler doesn’t have to be stressful and can actually save you money in the long run.

All new boilers need to be A-rated for fuel efficiency, meaning that minimal energy escapes into the atmosphere. Such boilers are almost always condensing boilers, which use a second chamber to keep water warm as it returns into the system. A-rated boilers are cheaper to run and save a lot of space compared with older models too.

What can I replace my gas boiler with?

There are lots of different options if you want to replace your existing gas boiler.

Perhaps the most obvious option is to get a new, A-rated gas boiler. Combi boilers, which heat both your home and your hot water, are the most common. These new models are small and work very efficiently, ensuring you save money.

If you have the space and want to go for a greener alternative, then heat pumps are a great idea. They come in two types: air source and ground source. The former uses the air to warm up water that can heat your radiators and provide warm water for the kitchen and bathroom, while the latter transfers heat from the ground outside your house to heat your property. Both are expensive, although you can get grants for installing one under the Boiler Upgrade Scheme, as much as £6,000. Installers will have to apply on your behalf.

You can also get money off biomass boilers via the same scheme. Instead of gas, these boilers use sustainable fuels, such as wood pellets. These release carbon dioxide, but much less than gas.

Can I get a gas boiler after 2025?

If you live in a home built before 2025, then you can get a new gas boiler installed.

However, properties built after this date will have to use green systems like heat pumps. The good news is that heat pumps and similar set ups will last years and will not require replacement unless they are faulty. It’s likely that any such product will be covered under your new home’s warranty, meaning the cost of replacement if it does become faulty will not fall to you.

Should I buy a combi boiler?

A combi boiler is a great option if you are looking to replace your old gas boiler. Such systems can heat both your home and hot water and are almost always based on condensing technology, meaning they can recycle any condensation that’s released to create more heat.

The other benefit is that they are often a lot smaller than older models, meaning you should get a lot of space back close to where your boiler is installed.

All new combi boilers must have an A efficiency rating, so they could also save you money too.
