What Is The ECO4 Grant?

The ECO4 scheme is a whole home scheme. It is designed to make substantial energy efficiency upgrades to the whole property to improve its EPC (energy performance certificate) rating.


Air Source Heat Pump

Your new energy-efficient heating system will produce four units of energy for every unit of electricity it absorbs. You could save thousands on your energy bills and your solar panels will help to power your home heating system.


Solar Panels

Solar Panels are installed on your roof as part of the scheme to help you generate your own clean energy and save on your energy costs. You can also sell any unused electricity back to the grid.


Insulation

Insulation is installed in your home as part of the scheme which can include roof, underfloor and wall insulation. Did you know that 35-45% of heat is lost through poor wall insulation, 20% through your roof and 10% through the floor.

Air Source Heat Pumps

  • What is the lifespan of an air source heat pump?

    The lifespan of an air source heat pump typically ranges from 15 to 20 years. Proper maintenance and regular servicing can help extend its lifespan.  

  • Are there any government grants for installing air source heat pumps?

    Yes, there are UK government grants available for installing air source heat pumps. The ECO4 Scheme allows homeowners to install renewable heating systems such as air source heat pumps in their properties for free. Other current schemes grants include the Boiler Upgrade Scheme . As part of this scheme, households can receive financial assistance to install heat pumps.  

  • What is an air source heat pump (ASHP)?

    An air source heat pump (ASHP) is a heating and cooling system that transfers heat between the indoor and outdoor air, providing energy-efficient heating and cooling for residential and commercial buildings.

  • How does an air source heat pump work?

    ASHPs work by absorbing thermal energy (heat) from the outdoor air in winter to heat indoor spaces.

  • Are air source heat pumps environmentally friendly?

    Yes, ASHPs are considered environmentally friendly because they use renewable heat sources (the outdoor air) and typically have lower carbon emissions compared to traditional heating systems like gas or oil furnaces.

  • What are the advantages of using an air source heat pump?

    Advantages include energy efficiency, lower operating costs, versatility (can provide both heating and cooling), and reduced carbon footprint. ASHPs also offer consistent heating and cooling performance.

     

  • How do air source heat pumps impact my home’s carbon footprint?

    Air source heat pumps (ASHPs) reduce your home’s carbon footprint by using renewable energy from the outdoor air to heat your home, rather than relying on fossil fuels like gas or oil. This means fewer greenhouse gas emissions, contributing to a cleaner environment and combating climate change.  

  • What maintenance is required for an air source heat pump?

    For air source heat pumps (ASHPs), regular maintenance includes cleaning or replacing filters, checking for airflow obstructions, and scheduling annual inspections by a qualified technician. This helps ensure optimal performance and efficiency, prolonging the lifespan of the system.  

  • Can air source heat pumps be used with existing heating systems?

    Yes, ASHPs can often be integrated with existing heating systems, such as furnaces or radiant heating systems, to provide supplemental or primary heating and cooling. Proper sizing and installation are essential for compatibility and efficiency.

  • How long do air source heat pumps typically last?

    With proper maintenance, air source heat pumps can last 15 to 20 years or more. Regular maintenance, including cleaning filters, coils and checking refrigerant levels, can help prolong their lifespan.

  • How noisy are air source heat pumps?

    The noise level of ASHPs varies depending on the model and installation. Many modern units are designed to operate quietly, especially when compared to older models.

  • Can air source heat pumps work in cold climates?

    Yes, modern ASHPs are designed to operate efficiently even in cold climates. They can still provide heat even in sub-zero temperatures. Over 60% of homes in Norway use air source heat pumps, where conditions are much colder than the UK.

Solar Panels

  • Are there government incentives for installing solar panels?

    The ECO4 Grant 

  • Can solar panels generate electricity on cloudy days?

    While solar panels are most efficient in direct sunlight, they can still generate electricity on cloudy days, albeit at a reduced rate. They rely on ambient light, so they will still produce some power even when the sun is obscured by clouds.

  • How much do solar panels cost?

    The cost of solar panels depends on factors such as panel type, system size, location, and installation costs. Prices have decreased significantly in recent years, and there are often incentives, rebates, or financing options available to help offset the initial investment. ECO4 Grant 

  • What maintenance do solar panels require?

    Solar panels generally require minimal maintenance, typically limited to periodic cleaning to remove dirt, debris, and bird droppings. Regular inspections for damage and ensuring proper wiring connections are also recommended.

  • How long do solar panels last?

    Most solar panels come with warranties ranging from 25 to 30 years, but they can last much longer with proper maintenance. Degradation rates are typically low, with panels losing around 0.5% to 1% of their efficiency per year.

  • What are the benefits of installing solar panels?

    Benefits include reduced electricity bills, decreased reliance on fossil fuels, lower carbon footprint, potential increase in property value, and energy independence.

  • Are solar panels suitable for my home?

    Solar panels can be suitable for most homes, especially those with unobstructed access to sunlight. Factors such as roof orientation, shading, and available space should be considered when determining the suitability of solar panels for a particular home.


     

  • What are solar panels?

    Solar panels, also known as photovoltaic (PV) panels, are devices that convert sunlight into electricity using semiconductor materials

Insulation

  • What does external wall insulation involve?

    The process may require preparation of the walls, installation of insulation and fixings, application of the render or cladding, and finishing touches. It often requires professional installation and may involve some disruption to the exterior of the building. External wall insulation (EWI) typically involves applying insulation boards or panels to the exterior walls of a building, followed by a protective render or cladding system. 

  • I already have loft insulation, do I still need more insulation?

    While loft insulation is essential for reducing heat loss through the roof, additional insulation in other areas of your home, such as walls and floors, can further improve energy efficiency and indoor comfort. It's worth considering insulation upgrades if your home lacks adequate insulation in these areas.

  • What does external wall insulation involve?

    External wall insulation (EWI) typically involves applying insulation boards or panels to the exterior walls of a building, followed by a protective render or cladding system. The process may require preparation of the walls, installation of insulation and fixings, application of the render or cladding, and finishing touches. It often requires professional installation and may involve some disruption to the exterior of the building.

  • Will internal wall insulation reduce the size of my room?

    Internal wall insulation can reduce the usable floor area of a room slightly, typically by a few centimeters. However, the impact on room size is generally minimal and can often be compensated for with adjustments to fixtures or furniture placement.

  • If I don’t have cavity walls, how can my walls be insulated?

    If your walls are solid (without cavities), insulation can still be applied internally or externally. Internal wall insulation involves adding insulation material to the interior walls, while external wall insulation entails adding insulation and an external finish to the outside of the walls. The Great British Insulation Scheme Apply  

  • What is insulation?

    Insulation is a material used to reduce the transfer of heat, sound, or electricity between different areas or objects. It is commonly used in buildings to improve energy efficiency and indoor comfort.

  • How is cavity wall insulation installed?

    Cavity wall insulation is installed by drilling small holes in the outer wall, injecting the insulation material into the cavity, and then sealing the holes. The process is relatively quick and minimally invasive, usually completed in a day for an average-sized home.

  • What are the benefits of cavity wall insulation?

    Benefits include improved energy efficiency, reduced heating and cooling costs, increased comfort levels indoors, and a smaller carbon footprint. Cavity wall insulation can also help prevent dampness and condensation issues.

  • What is cavity wall insulation?

    Cavity wall insulation involves filling the gap (cavity) between the inner and outer walls of a building with insulating material. This helps reduce heat loss through the walls and improves energy efficiency.
