MODEL COST GUIDE: RAINWATER GOODS
The prices in this table have been calculated for a typical two-storey, medium sized property offering around 125m2 of living space. We have assumed a conventional half-round profile of around 112mm. Designs such as deep-flow or decorative ogee will cost more. These indicative prices exclude VAT and
builder’s profit. The lifespan costs per year are intended for quick comparison only – they don’t account for the price of future maintenance work. Note: Self build projects qualify for zero-rated VAT on labour and materials (the latter will be reclaimed on completion), but renovators and extenders will usually need to pay the standard 20% rate on both aspects.
