📅 Typical Negotiation Timeline

S106 agreement negotiation typically takes 4-12 weeks from initial submission through to signing. Plan accordingly: initial scoping discussion (1-2 weeks), formal viability appraisal review (3-4 weeks), heads of terms negotiation (2-3 weeks), legal drafting (2-3 weeks), final sign-off (1 week).

🔄 S106 vs Community Infrastructure Levy (CIL)

S106 is negotiated, site-specific and covers necessary infrastructure and mitigation. CIL is fixed-rate, applies to floorspace, and funds strategic infrastructure. Many authorities use both — CIL for general items, S106 for site-specific requirements (e.g., on-site open space, bespoke highway works). Check your LPA's CIL charging schedule and policy framework.
