Guidance Notes

1. The above costs are purely indicative and are based on standard sized homes with no extensions,sound exterior wall surfaces and 2 storeys high

2. Any extra access equipment such as bridging a conservatory or tiled roof will be extra

4. Any specialised trades work such as moving electric cables, extending gas pipes and boiler flues or extending soil and waste pipes will be extra

5. UPVC window cill extensions are included but any wooden cill extensions will be extra

* Exact costs are dependant upon having a Green Deal Assessment & Survey carried out and are subject to the level of grant subsidy or cash back relevant at the time of the work being carried out but these typical costs for external wall insulation can be used for budgeting purposes
