Do you need planning permission in Stockton-on-Tees?
Most householder extensions in England fall under Permitted Developmentrights set out in the General Permitted Development Order (GPDO) 2015 — meaning you don't need full planning permission, provided you stay within the limits.
- · Single-storey rear extensions: up to 3m deep on terraced or semi-detached, 4m on detached, eaves under 3m. Above that, the Larger Home Extension prior approval route covers up to 6m and 8m respectively.
- · Two-storey rear extensions: up to 3m deep, must be at least 7m from the rear boundary, no balconies or raised platforms.
- · Loft conversions: up to 40m³ on terraced houses, 50m³ on detached/semi, no extensions beyond the original front roof slope facing a highway.
- · Outbuildings: must be single-storey, eaves under 2.5m, ridge under 4m (dual pitch) or 3m (other), within the curtilage of the dwelling and not used as a separate residence.

How long do Stockton-on-Tees planning applications take?▾
Statutory determination is 8 weeks for householder applications and 13 weeks for major schemes. Stockton-on-Tees can request an extension of time — check the application page on the council portal for the agreed determination date.
Does Stockton-on-Tees use a Local Validation List?▾
Yes. Every UK council publishes a Local Validation List on top of the national one. Applications missing items from this list are rejected as invalid before review. The applywell analysis cross-checks your drawings against Stockton-on-Tees's validation requirements.
Can I appeal a Stockton-on-Tees decision?▾
Yes. Householder appeals must be lodged within 12 weeks of the decision through the Planning Inspectorate. Around 25% of householder appeals succeed. The applywell decision parser extracts every refusal reason verbatim so you can see exactly what to address.
What's the difference between Permitted Development and full planning?▾
Permitted Development means you don't need to apply for full planning permission — but you might still want a Lawful Development Certificate (~£129) as proof for future buyers. Full planning is needed when you exceed PD limits, are in restricted designations, or build something not covered by the GPDO.
Do I still need Building Regulations approval?▾
Yes. Building Regulations are separate from planning — required for almost all building work regardless of whether you need planning permission. Approve via Full Plans (drawings reviewed up front) or Building Notice (inspections during construction).
