Questions about sheep's wool or natural loft insulation in Greater London

Which council covers my address in Greater London?

Do you cover the whole of Greater London?

Yes. We cover every town and village in Greater London, including Islington, Barking and Sutton.

Is sheep's wool insulation worth the extra cost?

In an older breathable house, or if you care about the material, often yes. In a modern semi with plasterboard ceilings the extra cost buys little performance.

It depends on the product's thermal conductivity. Some need slightly more depth than mineral wool to reach the same U-value, which we allow for on the quote.
