Several g15 members have completed mergers.
In November 2016 AffinitySutton and Circle Housing merged to form Clarion Housing Group, the largest housing association in the UK with 125,000 homes. Clarion has plans to build 50,000 homes during the next ten years, around two-thirds of which will be for affordable rent and low-cost homeownership.
The following month L&Q joined forces with East Thames. The L&Q group owns and manages more than 90,000 homes across London and the South East and is the largest landlord in the capital. With plans to deliver 100,000 new homes over the next decade, half of which will be affordable through shared ownership and rent, it will be one of the largest residential property developers in the country.
Optivo was formed in May 2017 through the merger of AmicusHorizon and Viridian Housing. It has 44,000 homes across London, the Midlands and south east England and will build 1,500 homes annually from 2021.
Peabody and Family Mosaic merged in July 2017. Family Mosaic is now a part of the Peabody group, although its subsidiary name will continue for a while. The Peabody Group has 55,000 homes spread across 29 London boroughs, with over 2,000 homes in Essex, Sussex, Hampshire and Kent. The group aims to build 2,500 new homes each year by 2021.
Most recently, Notting Hill Housing and Genesis Housing Association have agreed in principle to merge. The merger is expected to complete in early 2018 and will create a 64,000-home housing association. Notting Hill Genesis will be the largest provider of shared ownership homes in the country.
