What s106 costs here · from the deeds read so far
115 of the 605 agreements on file carry a pound total we have read: median £1k, mean £184k, largest £8.3m, £21m in total. Small undertakings dominate the median; the extraction is still running, so treat these as from the deeds read, not the borough total.

When does an agreement start? · share of approved schemes with an s106 on file, by size
Approved schemes since 2015 with a unit count in the proposal; “with s106” means we hold the agreement — a floor, not the council's full count. Smallest scheme here with an agreement on file: 1 unit.

Does it vary by borough? · yes
Share of approved 10+ unit schemes with an agreement on file (boroughs with 100+ deeds held) — highest Croydon 83%, lowest Kingston Upon Thames 30% · Lambeth 59%. On small schemes (1–9 units) agreements are rare everywhere except where a small-sites tariff applies: Lambeth 56%, Hackney 54%, Kensington And Chelsea 48%, Camden 44%.
Policy thresholds differ too — most boroughs seek affordable housing from 10 units (national threshold), some (Islington) charge a small-sites contribution from the first unit; the deed rate above is what actually happens, not what the policy says.
