Replace Storage Heaters Scotland

Envirohomes Renewables are leading the way in replacing old, energy inefficient storage heaters in Scotland. Our expert team instals modern electric storage heaters that will lower your energy bill and carbon emissions. Our team has installed hundreds of state-of-the-art electric heating systems in Scotland. We have all the necessary industry accreditations, including the PAS 2030 Certification which is renowned as the gold standard for home renewable suppliers.

We currently focus on providing fully funded storage heater replacements through the Government’s ECO 4 grant which is available for low-income households on benefits. Our team can help you through the process of securing funding, the details of which are given below.

Through the Energy Companies Obligation (ECO) Scheme, companies in Scotland and the rest of the UK must set funding aside that can be used to supply grants to make homes more energy efficient.

One of these grants is to replace storage heaters and upgrade homes’ electric heating systems.

About the ECO Scheme

The ECO Scheme was introduced in 2013, with the latest iteration, ECO4, running until March 2026. ECO4 replaced ECO3 in 2022.

The ECO Scheme provides grants and funding for qualifying households to replace boilers and electric storage heaters, and to install home insulation.

The scheme’s main aim is to reduce the country’s carbon emissions in an effort to combat climate change. This is in accordance with international agreements signed by the government.

It was also developed to help lower-income households or people on income-related benefits reduce their energy bills and improve their homes’ energy efficiency by paying for a variety of energy-saving measures.

What is
a Storage Heater Replacement
Grant in Scotland?

The Storage Heater Replacement Grant in Scotland allows eligible households (more on eligibility criteria below) to replace their electric storage heaters completely free of charge. It forms part of the ECO4 Scheme discussed above.

Through the scheme, as well as the Affordable Warmth Scheme (part of ECO4), faulty, inefficient or old electric storage heaters are replaced with modern, more energy-efficient options.

The grant covers up to 100% of the replacement and installation of the new electric heating system in the home. This grant is especially useful where properties are not served by gas mains or there is no gas central heating system, such as in apartment complexes.

Why apply for the Storage Heater Replacement Grant?

Older storage heaters are not effective and can cost homeowners a lot of money on their heating bills. This is a massive expense, especially for low-income households who may not have the money to spare.

Storage heater replacement grants allow homeowners to remove old, inefficient heaters and have modern storage heaters installed, free of charge.

The purchasing and installation of new storage heaters is typically incredibly expensive (around £200 for a new heater and another £150 for labour). By applying for the grant – should you be eligible – you avoid these costs

Do I Qualify
For The Storage Heater Grant?

The ECO4 funding scheme has a set of requirements for those who want to apply for free storage heaters.

Homeowners or tenants can apply for the grant if they receive the following benefits or credit:

  • Jobseekers Allowance
  • Employment and Support Allowance
  • Housing Benefit
  • Pension Credit (Savings Credit or Guarantee Credit)
  • Child Tax Credits
  • Universal Credits
  • Working Tax Credit

It is important to note, however, that you do not have to currently be claiming the benefits listed above. You must have claimed these benefits in the year (12 months) prior to the requested installation of a new storage heater.

If no one in the household has claimed any of the above benefits, you may still be eligible for a 50% discount on your electric storage heater replacement, as long as other eligibility criteria are met. A surveyor will be required to assess your property.

Additional requirements to be eligible for the grant include:

  • Being the homeowner or the primary tenant renting from a private landlord, with permission from the landlord.
  • The main source of heat is an electric heating system (e.g. electric panel heaters, radiators, storage heaters).
  • Your home’s Energy Performance Certificate rating is E, F or G.

Council houses and Housing Association properties

Those living in council houses and Housing Association properties may also be eligible for a free storage heater replacement; however, the qualifying criteria are different and the housing association should be contacted directly.

Why Are Storage Heaters Problematic?

Before discussing the disadvantages of inefficient storage heaters, we should get a better understanding of how these heating systems work.

How do storage heaters work?

Electric storage heaters contain heat-retaining bricks made from clay (ceramic bricks can also be used). These bricks have the ability to absorb and store heat, which is released when needed.

Electric storage heaters use an element to heat up the bricks during the night when energy tariffs are lower. The heat is then released during the day to heat up the home – with no electricity required to do so. This is useful, as electricity tariffs are typically more expensive during the day.

These heaters are flexible and efficient heating solutions, as they can be installed in most rooms, with no need for pipes or a central heating system such as radiators.

Newer storage heaters use advanced technologies that are far more energy efficient. There are different types of modern storage heaters available:

  • Fan-assisted storage heater: These can be installed as part of ECO4. Similar to traditional storage heaters, heat is stored overnight. During the day, a fan is used to extract cold air from the room through the heater; after which hot air is released via a vent. This type of heater makes use of a thermostat.
  • Combination convector storage heater: As with the above appliance, this modern type of heater can also be installed as part of the ECO Scheme. These heaters work similarly to traditional heaters but have a convection heater providing an alternative heat source or additional warmth.

Of Storage Heaters

Although modern storage heaters have come a long way in terms of energy efficiency, this type of heater remains fairly inefficient. However, for some residences, such as those not connected to gas mains, a storage heater is the only solution for a warm home.

Below are some of the main disadvantages of storage heaters

Not all heat is stored:

Unfortunately, not 100% of the heat generated during the night is stored and released during the day. This is particularly true for older heater models. That means that the heaters actually need more energy to heat up during the night than what is needed during the day. Convection heaters are able to store and release 100% of the available heat, making them much more efficient.

Electricity is expensive:

Electricity prices are currently three times higher than gas prices per unit of energy (kWh). As a result, it is still very expensive to run an electric storage heater in comparison to gas boilers and central heating.

Lack of temperature control:

Storage heaters – even the modern ones with thermostats – do not offer precision temperature control. Since heat is stored during the night, the heat released the next day may not be enough to keep the home at a comfortable temperature level. This is especially true on very cold days, of course.

The opposite also applies when a balmy day surprises you; the storage heater makes your home unbearably warm during the day.

The Advantages
Of Electric Heating?

Despite the disadvantages mentioned above, an electric heating system still holds many benefits for homeowners:

Low carbon emissions

Electric heating has a much lower carbon footprint than traditional fossil fuels such as coal and gas. As such, it is much better for the environment – a major plus.

Modern advances

Some may argue that electric heating has become outdated when compared to heat pumps or boilers; however, modern advances in the industry mean that electric heating has become incredibly energy efficient.

Safe and no risk to health

When compared to various other heating systems, electric heating does not pose any health concerns. There are no gases that can leak, and no burning or combustion occurs. There is no risk of explosions or carbon monoxide poisoning.

Less maintenance

As these electric systems have fewer components, they require less ongoing maintenance to ensure that all the parts are working.

Won't be left out in the cold

Less maintenance also means fewer repairs. As electric storage heaters are easy to maintain, there is no real risk of homeowners being left without any heating as breakdowns are very rare. As heat is stored in the system, you will have heating for a day, even if the heater breaks.

Lower installation costs

Although there are upfront costs involved, electric heaters are cheaper than heat pumps (£7,000 to £35,000) and gas boilers (£600 to £3,500).

Easy to install

As there are no moving parts, installation is quick and easy. The storage heater only needs to be connected to the electricity mains.


Electric storage heaters can be installed in any room in the house as they don’t require complicated piping.


An electric heating system is highly efficient; no heat is lost via flues or pipework. If you are able to combine your electric heaters with solar PV panels, you will not only have a very efficient heating system but also a reduced carbon footprint.


You won’t be exposed to loud noises and banging pipes with electric heating systems. Storage heaters are virtually silent when switched on and make no noise when releasing heat during the day.


Yes – to a certain extent.

Manufacturers must select from a list of approved suppliers for storage heaters to be installed under the ECO4 Scheme, including Creda, Dimplex, Heatstore and Elnur.

Installers may also select from a list of scheme-approved installers. Check the TrustMark status of your preferred installer, as this will indicate whether or not they have been approved for the grant scheme.

It is incredibly easy to replace storage heaters. Once you apply for the grant, a surveyor will come to the property as soon as possible to make sure that all eligibility criteria are met. Once approved, you can have new storage heaters installed within 24 to 72 hours.

Installation itself is very quick and can be done within a few hours.

The ECO4 Scheme covers more than just electric storage heater replacement. There are other home improvements related to energy efficiency which can be covered by ECO4 grants, including:

  • Replacing old or inefficient boilers
  • Draught proofing
  • Home insulation (including room in roof, underfloor, cavity wall and solid wall insulation)
  • Installation of solar panels and other renewable energy initiatives
  • Replacement of single-glazed windows with double glazing

For each of these grants, certain eligibility criteria will apply under the ECO4 Scheme.

The first step before applying for a free storage heater is to check whether you are eligible to receive the ECO4 grant. This can easily be done by filling in Envirohomes Renewables’ Check Eligibility Form. Thereafter, someone will be in contact to discuss the way forward.

Alternatively, you could also contact Envirohomes Renewables directly on 0141 459 0292.

Yes; if you have existing storage heaters in your home and these are being upgraded in accordance with the ECO4 grant, any existing storage heaters must be removed. This is part of the funding rules. The installer must prove that old electric storage heaters have been removed.

If you have other heating in your home, this doesn’t have to be removed – only old and inefficient storage heaters.

A modern storage heater will set you back between £150 and £200, depending on the model you opt for. Installation costs can range from £70 to £150 and will take about a day to complete. Purchasing a brand-new storage heater and having it installed can cost you anywhere from £220 to £350. The ECO4 grants will completely cover this cost if you are eligible.
