This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.
Ellesmere
Ellesmere is a market community near Oswestry in north Shropshire, England, noteworthy for its proximity to a variety of prominent Meres. The town is situated alongside Ellesmere (aka 'the Mere'), one of the largest natural meres in England outside the Lake District as well as one of nine glacial meres in the location. ('antarctic' indicates that the clinical depression occupied by the plain was the location of a block of ice that lingered at the end of the last Glacial period). These meres are various from those in the Lake District because they do not have a flow of water into them to maintain the level. A man-made island in the Mere was created in 1812 from dirt removed during the production of the yards at Ellesmere House. This was later called Moscow Island, as Napoleon was compelled to pull back from Moscow that year. The Mere has a site visitors' centre and is popular with birdwatchers, many of whom visit to see grey herons nesting. There are eight other meres close by: Blakemere, Colemere, Crosemere, Kettlemere, Newtonmere, Whitemere, Sweatmere and also Hanmer Mere. The civil church which makes up the community is Ellesmere Urban; the surrounding church, covering a big rural area, is Ellesmere Rural.
