East Suffolk, the local planning authority covering Leiston, approved 35 residential planning applications and refused 18 in Q3 2026 (1 July to 30 September 2026), with 105 still awaiting a decision. That is an approval rate of 66%. 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 2,885 homes, an estimated £662.4m 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.

East Suffolk covers more than one town in Suffolk, so these figures are authority-wide rather than specific to Leiston alone.
