About the ECO Scheme

The Energy Companies Obligation (ECO) Scheme, a cornerstone of sustainable living initiatives, mandates companies across Scotland and the UK to allocate funds for enhancing home energy efficiency. One such endeavor involves the replacement of outdated storage heaters, aligning with global efforts to combat climate change and uplift economically challenged households.

Delving into the ECO Scheme’s intricacies, the initiative traces its roots back to 2013, with the latest rendition, ECO 4, slated to continue until March 2026, superseding ECO 3 in 2022. Designed to fund initiatives targeting boiler replacements, electric storage heater upgrades, and home insulation enhancements, the scheme champions environmental stewardship while alleviating financial burdens on eligible households.

What is
a Storage Heater Replacement
Grant in Highlands?

The Storage Heater Replacement Grant in Highlands offers eligible households the opportunity to replace their electric storage heaters at no cost. This initiative is a component of the ECO4 Scheme previously outlined.

Under this scheme, along with the Affordable Warmth Scheme (a part of ECO4), outdated, inefficient, or faulty electric storage heaters are exchanged for modern, energy-efficient alternatives.

The grant covers the entire cost, up to 100%, of both replacing and installing the new electric heating system within the home. This grant proves particularly beneficial for properties without access to gas mains or lacking a gas central heating system, such as those found in apartment complexes.

Why apply for the Storage Heater Replacement Grant?

For starters, aging storage heaters are notorious for draining resources, burdening homeowners, particularly those with limited financial means.

The grant alleviates this strain by footing the bill for replacing outdated units with energy-efficient alternatives, sparing homeowners from substantial expenses typically associated with purchasing and installing new systems.

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.

In Highlands of Scotland, residents may find relief in a program offering discounts on electric storage heater replacements. Even if household members haven’t claimed specific benefits, they could still qualify for a 50% discount on replacements, subject to meeting certain criteria and a property assessment by a surveyor.

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

For those residing in council houses or Housing Association properties in the Highlands, there’s a possibility of receiving a complimentary storage heater replacement, although the criteria and application process may differ, requiring direct communication with the housing association.

Why Are Storage Heaters Problematic?

Before delving into the drawbacks of inefficient storage heaters, it’s crucial to gain insight into how these heating systems operate.

How do storage heaters work?

Electric storage heaters are equipped with heat-retaining bricks, typically composed of clay (although ceramic bricks are also viable). These bricks possess the capacity to absorb and retain heat, releasing it as needed.

During off-peak hours when energy tariffs are lower, an element within the storage heater heats up the bricks. This stored heat is then dispersed throughout the day to warm up the home, without the need for ongoing electricity consumption. This feature is particularly advantageous considering that electricity tariffs are generally higher during daytime hours.

These heaters offer versatile and efficient heating solutions as they can be installed in various rooms without necessitating pipes or a central heating system like radiators.

Modern iterations of storage heaters integrate advanced technologies for enhanced energy efficiency. Among the available options are:

  • Fan-assisted storage heater: This variant can be incorporated into the ECO4 initiative. Operating akin to traditional storage heaters, it accumulates heat overnight. During the day, a fan draws in cold air from the room through the heater, releasing hot air via a vent. Additionally, this type of heater incorporates a thermostat for temperature control.

  • Combination convector storage heater: Another contemporary option eligible for installation under the ECO Scheme. Similar to its predecessors, these heaters operate by storing heat overnight. However, they are equipped with a convection heater, offering an alternative heat source or supplemental warmth.

Of Storage Heaters

While modern storage heaters have made strides in energy efficiency, they still retain a degree of inefficiency. However, for certain residences, particularly those not connected to gas mains, storage heaters may represent the sole solution for maintaining a warm home.

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?

While electric heating systems may have drawbacks, they offer numerous advantages for homeowners in the Highlands:

Low carbon emissions

Electric heating produces lower carbon emissions compared to traditional fossil fuels like coal and gas, making it a greener option for the environment, which is particularly important in the pristine landscapes of the Highlands.
