What Type Of Boilers Can You Get On A Grant?

What Type Of Boilers Can You Get On A Grant?

Thousands of households across the UK have already benefited from a free boiler grant which has helped them replace their old and inefficient boilers with a new A-rated model. A new boiler can not only help you save large amounts on your energy costs but is a more eco-friendly option for the environment.

Under the ECO Scheme, the Government has committed to helping the UK meet its challenging carbon footprint reduction targets and helping low income households with the costs of heating their homes. This means assisting people by replacing their boilers for a more efficient and cost effective boiler.

So, if you are eligible to have your old boiler replaced, what types of gas boiler can you get under the Free Boiler Grant scheme?

Much will depend on the existing boiler set up you have in your home, presuming you have one at all. Boiler manufacturers, like Baxi and Worcester Bosch, have produced some innovative energy efficient boilers to replace or upgrade your current system. 

There are 3 main types of A-rated gas boilers that we can supply:

What is a combi boiler?

A combi (or combination) is the most commonly used gas boiler system and provides both central heating and hot water on demand in the home. It is a great economical choice for many homes and considered the most energy efficient, but is not always the best option for all.

A combi boiler will provide heat to your radiator, but differs from other boiler variants as it heats hot water for your taps only when you need it, as opposed to relying on a full tank of heated water when only a small amount of hot water is required. You do not have to wait for the water to heat before it is available for use and it is delivered at mains pressure, making it ideal for a powerful shower.

Main features of combi boilers:

  • Instant hot water at the turn of tap 
  • No requirement for a separate hot water cylinder or water tank
  • Available in a range of sizes to suit your home
  • Usually the most energy efficient boiler
  • Ideal for households with low hot water demand

What is a system boiler? 

System boilers, also known as closed vent boilers, control the heating and water separately, requiring both a boiler and a pressurised hot water tank. The system uses water directly from the mains water supply, and when the heating is switched on, the boiler heats the water and delivers it to the radiators.

Hot water is provided to taps and the shower via the system boiler heats which heats the water inside your water tank (which you will typically find in your airing cupboard). It takes time to heat, so you will usually have to switch your boiler on well in advance of needing a large amount of water, say if intending to take a bath.

Main features of system boilers:

  • Allows more than one hot water tap to be run at the same time
  • Economical running costs
  • Compact as key components are built-in to the body of the boiler instead of being external
  • Requires both boiler and water tank
  • Available in different sizes, but particularly well-suited to larger homes that use more hot water (e.g houses with several bathrooms)


What’s a conventional boiler/heat only boiler?

Conventional boiler systems are similar to system boilers as both require a separate hot water tank, but they also require a cold water tank, usually stored in the loft of a property that feeds water to the system. However, many components (diverter valve, circulation pump) of a heat only boiler are external to the boiler  and usually located next to the hot water tank.

Installing a heat-only boiler is usually straightforward as they can be added to an existing system. They are easy to use and will normally have a switch so you can turn the hot water on in advance of needing it.

Main features of conventional/heat-only boilers:

  • Usually relatively simple to install
  • Compact in size
  • Allow you run more than one hot water tap at the same time
  • Can replace any existing heat-only boiler


Pros of cons of gas boiler types

Type of Boiler Pros Cons
  • Contains almost all components within the boiler itself, which makes the boiler system compact and tidy
  • Absence of a cold water or feed and expansion tank in the loft
  • Immediately get hot water heated on demand 
  • Moving parts within the boiler unit, so greater potential for things to break than with other boilers
  • Only able to use hot water from a combi boiler system for one task at a time. 
System Boiler
  • Good for large homes where hot water may be required in multiple places in the home at the same time
  • No need for a large cold water tank in the loft
  • Ideal for areas with low water pressure
  • Requires space for a hot water cylinder
  • More expensive to install than basic combi boilers
  • Not as efficient as combi boilers as heat is lost from the stored hot water in the hot water cylinder.
  • Need to wait for water to heat up once store hot water has been used up
Conventional/Heat Only Boiler
  • Better suited to larger households where several people need hot water at the same time
  • Can be the best option for an older property with an old heating system.
  • requires two tanks in the loft and a hot water cylinder to run effectively
  • Don’t provide hot water on demand, so you have to wait for the water to heat up
  • Less efficient than combi boilers because heat is lost over time from the hot water cylinder

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!

If you are in receipt of any of the benefits mentioned, just fill in your postcode to confirm whether you are eligible or not for a FREE boiler grant.

Who is eligible for a grant?

If you are a homeowner living in your property, with a 7+ year old boiler and current receipt of one or more of the listed benefits, you qualify to apply.

For any further information on your eligibility, get in touch with us today.

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.
