In reference to your article “OFT clears housebuilders – but raises zero-carbon fears” (26 September, page 11), while it is true that zero carbon could potentially prove a barrier for small housebuilders, we strongly believe it is also an opportunity.

To help this group meet these targets we must ensure that small housebuilders and self builders have access to the right technology and knowledge.

The fact that the Zero Carbon Hub has been established is testament to the commitment of government and the housebuilding sector to ensuring potential barriers are broken down. Over the coming months the Hub will be developing a programme of activity to support small homebuilders including a series of exemplar homes on sites across the UK.
