Planning Permission in Darlington
Unitary Authority in North East · Last updated April 2026
Darlington is a unitary authority in the Tees Valley, renowned as the birthplace of the railways — the Stockton & Darlington Railway, the world's first public steam-hauled passenger railway, opened here on 27 September 1825. The borough combines a thriving market town with surrounding villages and countryside, anchored by a rich Victorian commercial centre and significant railway heritage including the Grade I listed Skerne Bridge, the oldest railway bridge in the world still in use.
The Darlington Borough Local Plan 2016–2036 was adopted in February 2022. Two major garden village allocations — Skerningham (4,500 homes) and Greater Faverdale/Burtree — will shape growth over the plan period. The £140m Bank Top Station transformation adds two new platforms and a transport interchange, due for completion spring 2026. The £35m Railway Heritage Quarter at North Road Station creates an internationally significant museum for the S&DR bicentenary. The borough has 2 made neighbourhood plans (Middleton St George and Low Coniscliffe & Merrybent).
Planning application fees are set nationally and increased in April 2025. A householder application costs £528. The council offers pre-application advice with fees set out in the Pre-Application Advice Charter (from April 2025). Darlington does not charge CIL; developer contributions are secured through Section 106 agreements. A borough-wide Article 4 direction for HMOs comes into force in July 2026, requiring planning permission for all HMO conversions.

Permitted development in Darlington
Permitted development rights in Darlington are generally unrestricted outside conservation areas, with standard national rules applying to householder extensions, loft conversions and outbuildings. A borough-wide Article 4 direction for HMO conversions (C3 to C4) has been confirmed and comes into force on 28 July 2026, after which all such conversions will require planning permission. A separate Article 4 direction applies within the S&DR: Northgate Conservation Area, restricting certain external alterations to protect its railway heritage character. The two garden village allocations at Skerningham and Greater Faverdale have specific Design Code SPDs (adopted 2023 and 2022 respectively) setting detailed design expectations for new development.
What Darlington expects from your project
The council's Design of New Development SPD (2011, planned for update) guides design quality across the borough. Specific Design Code SPDs have been adopted for the two garden village sites: Skerningham (September 2023) with health and wellbeing-led 10-minute walkable neighbourhoods, and Greater Faverdale/Burtree (July 2022). The borough's character ranges from the dense Victorian commercial streets of the town centre to scattered villages and farmsteads in the surrounding countryside. Properties along the River Tees (southern boundary) and River Skerne face flood risk considerations. The council identifies 19 Scheduled Monuments and 3 Registered Parks and Gardens across the borough.
