I recently recieved a request for information concerning grants to help with paying for insulation.  I found this to be a very helpful website, so if you are looking for this so please have a look (http://www.freeinsulation.co.uk).  There is also an option on the site to enter your postcode and see if your area is eligible.  Here is some information from the site about the grants:

Insulation Grants are available to completely cover the cost of Cavity Wall Insulation & Loft Insulation for your home. If you are not entitled to one of the full insulation grants, you can still receive a grant for up to 70% of the cost!

All Home Insulation Grants are backed by the UK Government and they do not have to be re-paid! Any home owner or private tenant qualifies for a grant, regardless of circumstances. Take advantage of this fantastic offer now while grants are still available.

Free Insulation grants are available to private households where anyone is aged 70 and above or anyone is in receipt of certain benefits, tax credits or allowances. All other home owners and private tenants will still qualify for a partial grant and the table below shows some typical examples of the amount to pay after the grant has been applied.
