Grant System Boilers

Free System Boilers

If replacing your inefficient boiler is long overdue then it is worth looking into whether you could benefit from a free system boiler under a generous Government backed scheme. UK households can receive assistance under the ECO Scheme to replace their old boiler and replace them with an energy efficient boiler as part of a commitment to reach carbon footprint reduction targets.

The Scheme applies to different types of boiler, including system boilers, so if you are eligible you may be in line for a grant to replace your system boiler with a much more energy efficient one. Receiving a free system boiler will bring benefits for you in terms of savings on future heating bills as well as being much better for the environment.

If you are looking to see if you are eligible for a grant system boiler, read on to discover some of the features and benefits of having one in your home…


What is a system boiler? 

A system boiler consists of a boiler and a water cylinder. The boiler heats water direct from the mains water supply when you switch the heating on and delivers this to the radiators. To provide hot water to taps, the system boiler heats the water inside the water cylinder, and has to be switched on in advance in order for hot water to be generated.

Main features of system boilers:

  • Requires a boiler and hot water cylinder
  • Allow multiple hot water taps to be run concurrently
  • Economic to run as heated only when required


Who should use a system boiler?

System boilers could be used in any home, but are best suited to households with large hot water demand, for example multiple bathrooms likely to be in use at the same time. This makes them most suitable for large families and for households with a large number of radiators.


What are the pros and cons of using a system boiler?

System boilers are the best option for some homes, whereas a combi boiler may be more than adequate for others. It can often depend on what your current set up is. Here are some of the pros and cons of using system boilers in the home:


  • Can handle high hot water demands
  • No need for a large cold water tank in the loft
  • Uses mains water supply so pressure is improved 
  • Economical way to provide hot water


  • Requires space for a hot water cylinder (likely in an airing cupboard)
  • More expensive to install than basic combi boilers 
  • Not as efficient as combi boilers as heat is lost from the heated water in the storage cylinder if it is not used up
  • Lack of instant hot water means having to wait for water to heat up 


Are system boilers efficient?

System boilers may not be as efficient when heating the hot water tank as the water is heated and stored (at which some heat may be lost) rather than being created and used at the same point. However, if you are replacing an old system boiler with a new one, it is inevitable that this will be much more efficient.

Old boilers can see their efficiency reduced down to as little as 60% whereas a new A-rated system boiler is generally 90%+ efficient, meaning that a larger portion of the fuel used is converted to heat.


How much could a new system boiler save me?

A new system boiler will bring efficiency savings meaning that you could reduce your heating bills by as much as £300 annually. Plus if you qualify for a grant for a new system boiler, your new heating and hot water system will come with a lengthy warranty and will also protect you against maintenance and repair costs in the coming years.


What brands of boiler could I have installed if I’m eligible for a free system boiler grant?

We focus on providing two main boiler brands – Baxi and Worcester Bosch – which we believe are best suited to the needs of our customers. Both come with excellent warranties providing you with peace of mind with your new system boiler. If you qualify for a grant for a system boiler, we will assist you with identifying which boiler is best suited to the needs of your household and current set up.


What size system boiler do I need?

Domestic boilers usually range from 24kW to 42kW in size and you need one that is just the right size for your requirements. Having one too small will not be able to heat your home adequately and will not produce enough hot water for your needs. A boiler that is too big will unnecessarily use too much fuel. 

Arugh rule of thumbs suggests the following:

 1.5kW per every radiator = 3kW for your water cylinder

It is possible to ditch your system boiler and convert to a combi boiler but this could prove expensive due to extra materials and work required.

What is the ECO scheme?

The Government-backed Energy Companies Obligations (ECO) scheme places an obligation on the largest energy suppliers – including npower, E.ON and British Gas, SSE, EDF and Scottish Power – to help make British households more energy efficient and help reduce their energy bills.

By offering free grants towards new energy efficient boilers to eligible households helps reduce the cost of heating the home and contributes towards the overall drive to reduce carbon emissions. Those who benefit from the ECO scheme with a free boiler grant could save several hundred pounds on their heating each year.

How much will a new boiler save me?

If we consider an old boiler may only be operating at 65% of its efficiency you could literally be wasting 35p of every pound you spend on energy.

The good news is that new boilers with an ‘A’ rating can operate at around 90% + efficiency which translates into less than 10p wastage. So, you could save as much as £300 per year by replacing your old and inefficient boiler with a brand new one with an ‘A’ rating. Imagine what you could do with that money!

How is the boiler grant free?

Under the government boiler scheme, it is the leading energy companies who are under the obligation to provide the grants for replacement boilers to those who qualify.

Our fees for removal, installation and aftercare are sourced through the scheme and its grants, so you won’t have to pay out to cover our costs during the process.

This allows you to get your brand new boiler at a fraction of the cost.

Does the boiler grant have to be repaid?

Boiler grants are free and do not have to be repaid at any time. There are no hidden terms and conditions to worry about.

The scheme aims to help low income households improve their home energy efficiency and any grants are non-repayable. Those eligible for a grant will either get a free or a subsidised boiler replacement. In some cases a contribution may be required towards the cost of the new boiler, but this will be made clear from the outset, following a free assessment at your home.

How long does installation take?

We understand that many of our clients will be eager to know exactly how long it takes for their new boiler to be fully functional in their home, particularly if your current boiler has issues.

Specific schedules can vary a little depending on availability of staff and equipment in your region at a given time, but in general, it should be no more than 2-3 months from the moment you apply through to completed installation.

What type of boiler can I get fitted?

Under the ECO scheme, you can have a brand new A-rated, energy efficient combi or system boiler fitted which will have an efficiency usually in excess of 90%.

We offer a range of boilers including Baxi, Worcester Bosch, Vokera and Ideal.

Will the boiler come with a warranty?

If you receive a new boiler through a boiler grant,  your installation will be covered by the same warranty you would receive from that boiler manufacturer.

The length of any warranty varies between brand and different boiler models but would usually be anything from 2-7 years. All aftercare will also be provided as part of the service to you.
