What Are Section 106 Agreements?
Grounded in the Town and Country Planning Act 1990, S106 agreements are legal obligations designed to mitigate the impact of development. They must be:
- Necessary to make the development acceptable in planning terms
- Directly related to the development
- Fairly and reasonably related in scale and kind
Typically, these agreements cover contributions for highways, education, affordable housing, and community facilities. They are binding on the land and can be modified or discharged under certain conditions.
The Scale of Unspent Contributions
According to recent Home Builders Federation (HBF) research, local authorities in England and Wales are holding over £8 billion of infrastructure payments by developers, including more than £6 billion from S106 agreements and nearly £2 billion from the Community Infrastructure Levy (CIL). Alarmingly, only £20.6 million has been returned to developers in the last five years
