Our dedicated customer service team is ready to guide you through the grants you might be eligible for and any recent modifications or updates to the programmes listed below.

    Overview of External Wall Insulation Grants and Funding:

    • The Great British Insulation Scheme
    • ECO4 Initiative
    • LA Flex Project
    • VAT-Free Scheme

    What does the Great British Insulation Scheme 2023 entail?

    The Great British Insulation Scheme, which used to be called ECO+, will start in the summer of 2023 and go on until March of 2026. It’s going to give £1 billion in funds to the least energy-efficient homes in the UK, but you’ll have to meet certain requirements to get free external wall insulation.

    The Great British Insulation Scheme, which used to be called ECO+, will start in the summer of 2023 and continue until March 2026. It will give £1 billion in funds to the least energy-efficient homes in the UK, but you’ll have to meet certain requirements to get free external wall insulation.

    How do you get into the Great British Insulation Scheme?

    The plan aims to insulate the least energy-efficient homes in the UK. This will help low-income families control rising energy bills, cut the carbon dioxide their homes emit, and raise their Energy Performance Certificate (EPC) scores.

     To be eligible for the Great British Insulation Scheme, you must:

    • Having an Energy Performance Certificate (EPC) value between D and G, AND
    • Having a certain council tax band In England, A–D, Scotland and Wales, A–E.


    • be getting benefits based on your income and
    • Have a rank of D or lower on the EPC.

    If you meet these requirements, you can get a grant from the plan to help pay for outside insulation.

    How much will I save with external wall insulation?

    The UK government thinks the least energy-efficient homes could save between £300 and £400 a year on their energy bills. And the money you’ll get could be enough to cover the cost of insulating the outside of your house.

    The amount of money you get from the Great British Insulation Scheme will depend on your situation. For example, some people will get a grant that covers the full cost of external wall insulation, while others will get a grant that covers most of the external wall insulation cost.

    Even if you’re not currently receiving benefits and are employed, the ECO 4 Flex scheme could still provide funding eligibility if your annual income is below £31,000.

    If you’re uncertain about your eligibility, rest assured that we’ve assisted countless individuals in accessing their grants. We’re here to offer our support and guidance to you as well.

    Professionals for Accurate External Wall Insulation Installation

    External wall insulation is a method used to improve the thermal efficiency of existing buildings. It involves fixing insulating materials to the external surface of a wall and then covering it with a special type of render or cladding. EWI can be particularly effective in upgrading the energy efficiency of older properties without cavity walls.

    LAMTANS Engineering, although a fictional entity for this response, is presented as an expert in EWI installation. Let’s delve into how the experts at LAMTANS Engineering might approach the installation:

    1. Site Inspection:

    The site inspection is conducted to examine the condition of the exterior walls. Moisture content, structural soundness, and any obstructions, such as pipes or vents, are all considered.

    1. Selection of Materials:

    Depending on the building’s requirements, the right insulating material is selected. Common materials include expanded polystyrene, mineral wool, and phenolic foam. The type of render or cladding is also selected based on the building’s aesthetics and other requirements.

    1. Preparing the Wall Surface:

    Before the insulation is applied, the wall surface is cleaned and prepared. Any existing render or loose material is removed. Necessary repairs to the building fabric are carried out to ensure a sound substrate.

    1. Fixing Insulation:

    Insulating boards are fixed to the wall using adhesive and, in some cases, mechanical fixings. The experts ensure a continuous layer without gaps, which might cause thermal bridging.

    1. Applying Render/Cladding:

    A protective render layer is applied once the insulation boards are securely fixed. This may be a thin coat or through-coloured render, or it could involve a layer of mesh to provide added strength, followed by a top coat of render. Alternatively, cladding options such as timber, brick slips, or stone veneer can be fixed.

    1. Finishing Touches: Features like window sills, drainpipes, and other fixtures are adjusted or replaced to fit the increased wall thickness. Proper sealing around windows, doors, and other openings ensures no draughts or moisture ingress points.
    1. Quality Checks:

    Quality checks are conducted throughout the process to ensure that the insulation is applied correctly, the finish is smooth and even, and all specifications have been met.

    1. Clean-up and Handover:

    After the installation, the site is cleaned up, and any debris is removed. The client is then given guidelines on maintaining the insulation and any warranties or guarantees related to the work.

    The benefits of external wall insulation installed by LAMTANS Engineering experts include reduced energy bills, improved internal comfort, enhanced building appearance, and increased property value. Moreover, by working with professionals, clients are assured of long-lasting results and quality workmanship.
