Loosen planning restrictions on old windows in listed buildings

Planning are too strict with applications for changing old single glazed windows to double glazed in old houses. The process of applying is also very complicated and you basically need an architect to draw up drawings of your existing windows etc! My house loses so much heat through the single glazing. 

Why the contribution is important

Homes being well insulated makes a vast difference to energy consumption.

    The only problem with putting modern windows in an old property is damp you have to ensure your old property is completely insulated

    New double-glazing has one of the longest payback periods of all energy efficiency measures due to their cost. Broadly speaking the lower the cost of the energy improvement the more effective it is in terms of saving carbon, largely due to the amount of embodied carbon in the new window. D/g units should be seen at one end of a scale of improving the performance of existing windows - whether they're in listed buildings or not. For instance closing shutters will reduce heat loss by c60% compared to d/g units at c79%, but obviously only when they're shut. An ordinary roller blind will reduce heat loss by c22%, a roller blind with low emissivity film on the window facing the blind c45% ; secondary glazing c63%, secondary glazing and shutters c75%.
