registered social landlord Nucleus Housing Group has been placed under supervision by the Housing Corporation in the same week that details emerged of a merger with London & Quadrant Housing Trust.
The intervention follows concerns over Buckinghamshire-based Nucleus' performance on property management and development.

The corporation gave Nucleus two amber ratings in its "traffic light" assessment in September. There were "weakness and poor performance" in repairs and many performance indicators showed worsening performance.

It also failed to meet development targets for its £1.2m grant development programme.

The merger would mean L&Q controlled almost 40,000 homes across the South-east

The corporation will work with the association to produce a revised strategy.

The supervision of Nucleus, which is mostly made up of 4400-home Beacon Housing Association, puts a question mark over the merger. If it goes ahead, it would leave all Nucleus' subsidiaries intact and create an enlarged group covering London and the South-east that would mean L&Q controlled almost 40,000 homes.
