Small amount of grant funding was sourced from energy suppliers.


Green Lifestyle



Following installation and 12 months of living in their refurbished properties the residents were contacted to gauge their opinion of the work.  All were pleased with the end result.  The work also included re-roofing and insulating sloping ceilings only easily accessible after stripping off the roof covering.
