Full details of the rules relating to Cavity Wall Insulation Grants have yet to be finalised for the new ECO Scheme which started on 1st April 2017.
Cavity Wall insulation grants were previously available under the Carbon Emissions Reduction Obligation, not the Affordable Warmth Obligation.
ECO Scheme and Insulation Grants
Free cavity wall insulation is funded by the Government’s Energy Companies Obligation or ECO, and applications may be subject to technical surveys and other eligibility criteria. ECO funding covers the cost of the survey, the insulation material and installation.
Also, sometimes work needs to be carried out which the funding does not cover. You will be offered the chance to meet these extra costs yourself but if you choose not to, you will not benefit from free cavity wall insulation.
Most homes in the United Kingdom have external walls with a cavity between two layers of brick work. Cavity wall insulation is used to fill that gap, which helps to keep in the warmth, which in turn saves energy and reduces your heating bills.
Cavity wall insulation can also help to reduce condensation inside your home if this is a problem on your external walls. In general terms, the need for cavity wall insulation will probably apply to your home if:
• The property was built between 1924 and 1982
• The external walls have a cavity at least 40 mm and it is not insulated
• The brick work is in good condition
• The walls are not exposed to driving rain
An installer can carry out a boroscope inspection to ascertain whether your home already has cavity wall insulation installed and this involves drilling a small hole in the external wall to check if the cavity is filled or not.
