Happy Days!

 All homeowners and private tenants qualify for a full 100% grant regardless of financial circumstances.

If your home was built after 1920, the chances are that its external walls are made of two layers with a gap or cavity between them. Cavity wall insulation fills that gap, keeping the warmth in - to save energy. It can also help reduce condensation inside the house if this is a problem on your external walls.

Your home will usually be suitable for cavity wall insulation if:

  • its external walls are unfilled cavity walls

  • your cavity is at least 50mm wide

  • the masonry or brickwork of your property is in good condition

  • it is more than ten years old (most newer houses will have insulation already)

  • the walls are not exposed to driving rain.

If your house was built in the last ten years or so, its walls are probably insulated already. 

What if there is damp? 

If you have any damp patches on your external walls then they should not be insulated until the problem is sorted out. Speak to us about damp prevention. 

How is insulation installed? 

Filling cavity walls is not a job you can do yourself. We do the job in around two hours for an average house with easily accessible walls; it is simple, quick - and with no mess. 

Most installers use Cavity Insulation made from shredded mineral wool (glass fibre), but we always use polystyrene beads, that can reduce the amount of heat escaping from your home by up to 35%. Cavity Wall Insulation saves up to £135 per year on energy bills and reduces CO2 emissions by up to 610kg. 

  • Most homes built of brick between 1920 and 1999.

  • Polystyrene beads in all cases.

  • Blown into the gap between two layers of bricks.

  • Installed from the ground floor to the roof. 

N. B. Cavity wall insulation is achieved by blowing either mineral wool or small polystyrene beads through a series of small holes drilled in a careful pattern in your walls. Wool is a little cheaper, but bead offers better overall thermal performance and requires smaller holes and fewer holes to be drilled in your mortar joints during installation. 

Our Installers are among the best in the business, and they will make good the holes with closely-matching filler, so that you have a first-class result with the minimum of fuss and disruption. Most of our customers are amazed at how quickly and neatly this operation can be carried out and our work is guaranteed for 25 years by CIGA – the Government-backed Cavity Insulation Guarantee Agency – offering you complete peace of mind (see below).


  • The Government's new Green Deal will replace Insulation Grants.
  • Loans will be issued instead and will be repaid from bill savings.
  • Insulation grants are still available and do not have to be repaid. 
  • This will only last for the next few months!
    Cavity Wall Insulation grants are running out so to claim your Insulation grant, you need to act fast before the scheme comes to an end in 2012. Loft Insulation grants are scheduled to be replaced by a loan-based system called the Green Deal.

     But now time is running out!


    The Green Deal starts in October, but the Best Deal is available here and now, but not for long. Owing to recent Government laws the existing Grant Schemes will be axed.

    The existing Grants do not have to be repaid at all , you simply pocket your energy savings (which is about £135 p.a. for cavity wall insulation).



    Peace of Mind

    The Cavity Insulation Guarantee Agency provides independent 25 year guarantees for Cavity Wall Insulation fitted by registered installers in the UK and Channel islands.

    The Government regards cavity wall insulation as the most effective energy savings measure that most people can carry out on their homes and a major contributor to reducing emissions of carbon dioxide, the main greenhouse gas.  

    The Cavity Insulation Guarantee Agency was established in consultation with the Government's Energy, Environment and Waste Directorate (a division of DETR) to provide householders with an independent, uniform and dependable guarantee covering defects in materials and workmanship.

    Independent research carried out for the Department of the Environment, Transport and the Regions (DETR) has confirmed that cavity wall insulation is a very reliable process. 

    Problems are therefore extremely rare, but if they do occur, CIGA has the expertise to ensure that they are swiftly rectified. 

    CIGA also operates and administers the Cavity Wall Insulation Self Certification scheme (CWISC) in association with the British Board of Agrément. The scheme provides homeowners with the comfort of knowing that work by registered contractors complies with the requirements of the Building regulations.
