The plan should offer guidance on those circumstances which might dictate a site being considered unsuitable for affordable housing provision.

Where commuted sums are obtained it will be helpful to the community to understand where those sums will be spent and in what timescale.

The policy indicates commuted sums will be acceptable only in exceptional circumstances, and is supported. However, it would be helpful if the plan offers guidance on the circumstances where a site might be considered unsuitable for affordable housing. This is not a decision which should be left to the developer. Where commuted sums are obtained it will be helpful to the community to understand where those sums will be spent and in what timescale, to avoid the potential for all sites suitable for affordable housing in the areas where they are needed, being used in preference for open market housing.
