Woodbrook – fuel supply • Fuel comes from local willow coppice – 18% moisture content • A selection of local wood fuel suppliers available • 5 tonne deliveries at present – would mean 1 per day in peak heating season

Woodbrook – customer and developer perspectives • High sustainability standards have been led by developer • Want to establish themselves in the market as a leader in sustainable, zero carbon development • For residents, have been some issues with slow response time of heating – training needed in how to use systems (lower output over a longer time) • Plots have been selling well, despite market turn down
