A quarter of heat is lost through the roof in an non insulated home. Insulating your loft is a simple and effective way to reduce heat loss and reduce your heating bills. Loft insulation is effective for at least 40 years and it should pay for itself many times over.

 What is cavity wall insulation?  

Cavity wall insulation is one of the best and most affordable ways to improve your home's energy efficiency. 
Houses in the UK mostly have either cavity walls or solid walls: 
Cavity walls are made of two layers with a gap or ‘cavity’ between them. If your home was built after the 1920s, it's likely to have cavity wall 
Solid walls have no gap, so they can’t be filled with cavity wall insulation. If your home was built before the 1920s, it's likely the external walls are solid walls rather than cavity walls 
Cavity walls can be insulated by injecting insulation into the cavity from the outside through drill holes in the outside walls. Insulation is usually mineral wool or polystyrene beads, or polyurethane foam. Cavity Wall Insulation comes with a 25 year guarantee. 

 How can I tell if I have a cavity wall? 

There are some common ways to tell if your property has a cavity wall: 
It was built after 1920; homes built within the last 40 years almost certainly do 
It has walls more than 260mm thick 
It has brickwork like one of these picture examples
