Tonbridge and Malling, the local planning authority covering Tonbridge, approved 8 residential planning applications and refused 7 in Q3 2026 (1 July to 30 September 2026), with 104 still awaiting a decision. Too few decisions were captured in the period to state a reliable approval rate. Planning figures come from local planning authority records compiled by Landstack, retrieved on 3 October 2026. Councils and Landstack can take several days to publish decisions, so decisions made in the final days of Q3 2026 may not all be included yet.

Schemes approved in Q3 2026, together with those still awaiting a decision, propose around 2,349 homes, an estimated £950.4m of development value at local sale prices. Treat the unit total as an upper bound, since an outline permission and its reserved-matters application both count.
