Save energy by changing your own house

Isolation 

In order to save your money by reducing your energy and water costs while reducing your impact on the environment, it is essential to ensure your home is adequately insulated. 

Standards of insulation in new housing are considerable higher than they are in older housing. However, properties built before current standards make up by far the largest proportion of the UK housing stock. In order to improve energy efficiency, reduce heating and hot water costs and to reduce CO2 emissions the fitting of insulation into existing housing stock is essential. 

The following types of insulation can be affective:

-Hot water insulation 

-Roof insulation 

-Wall insulation - both cavity and solid wall 

-Floor insulation 

-Double and secondary glazing
