Do I need planning permission in Dewsbury?
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
The planning position for a specific Dewsbury address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Working in Dewsbury
Postcode districts we cover around Dewsbury include WF5, WF12, WF13, WF14, WF16, WF17. We also work in nearby Batley (1 mile), Ossett (2 miles), Heckmondwike (2 miles), Liversedge (3 miles).
Just over the South Yorkshire border, Darton is about 8 miles away. Yorkshire and the Humber combines stone-built terraces in the Pennine towns with brick semis and newer estates elsewhere, so materials and roof details need matching with care.
