Ok for those that are interested and may have a similiar issue, I found the following information, it seems the council can do what they like in terms of the division of ah and social as long as they have enough houses. Will post more if I find anything else to the contrary;

Part 5 affordable housing
Part 5 of the Development Acts 2000-2002 allows a local authority to require developers to set aside up to 20% of new developments of five or more houses for social or affordable housing. The local authority will decide how much (if any) of the 20% will be affordable, social, voluntary, housing etc. This is determined in consultation with the developer, taking into account the appropriate percentage in the development plan.
There are no rules about where affordable houses should be located in new developments.
It is for the local authority to decide which homes should be designated as affordable housing, as appropriate. For example the affordable houses may be peppered through the development/estate or may be grouped in pairs, in areas, etc. The proximity of these homes will all depend on what the local authority approve as most appropriate for the area and most appropriate for the residents of these homes.
Eligibility for Part 5 affordable housing
You are eligible to buy an affordable house provided under Part 5 of the Planning and Development Acts 2000-2002 if 35% of your income is not sufficient to enable you to buy a house.
Affordable Housing Initiative
The Affordable Housing Initiative (AHI) was introduced under the Sustaining Progress agreement. Under this initiative the Office of Public Works provides land on which new houses are built and sold.The AHI is meeting the needs of those who would formerly have been able to purchase a house, but now find themselves priced out of the market.
