Dear Mrs Argyle. Thank you for your post. The grants are worked out by taking into consideration age, location, energy provider and benefits received. The older someone is and the more benefits they are receiving the more likely it is that their insulation will be completely free. In your circumstances i would say you would ber very close to attaining 100% free insulation but please fill in our form and one of our surveyors will calculate this for you when they survey your property. The form can be found at http://www.eviee.co.uk/grants.asp.
