Berkshire has had no county council since 1998 — six unitary authorities run planning independently, and they differ sharply. Windsor and Maidenhead is Green Belt and heritage-led; Reading and Slough are urban; West Berkshire is a National Landscape.

Berkshire County Council was abolished in 1998, and unusually for southern England there is no two-tier structure at all. Six unitary authorities each act as the sole planning authority for their area: the Royal Borough of Windsor and Maidenhead, Reading Borough Council, Slough Borough Council, Wokingham Borough Council, Bracknell Forest Council and West Berkshire Council.
That matters practically because there is no county tier to fall back on for minerals, waste or highways coordination in the way a shire county provides. Every consultation is internal to the unitary, which tends to make determination timescales more predictable but local policy more variable.
Eastern Berkshire sits in the Metropolitan Green Belt, covering most of the Royal Borough of Windsor and Maidenhead outside the towns, and parts of Slough and Bracknell Forest. The disproportionate-addition test applies there in the same way as in Surrey and Hertfordshire.
The Thames is the second constraint and the one most often underestimated. Flood Zone 2 and 3 designations follow the river through Maidenhead, Windsor, Datchet, Wraysbury and into Reading, bringing a flood risk assessment, minimum finished floor levels and, on many sites, a requirement for flood-resilient construction and compensatory storage. It regularly rules out basements outright.
Heritage is concentrated around Windsor, where the castle, the Great Park and the historic town core produce dense conservation-area and listed-building coverage, and around the older cores of Maidenhead, Reading, Newbury and Hungerford. In the west, the North Wessex Downs National Landscape covers much of West Berkshire, adding a landscape and visual test to rural schemes.

One of six unitary authorities — Windsor and Maidenhead, Reading, Slough, Wokingham, Bracknell Forest or West Berkshire. Berkshire County Council was abolished in 1998, so there is no second tier and the unitary is the sole planning authority.
If the property sits in Flood Zone 2 or 3 — which follows the river through Maidenhead, Windsor, Datchet, Wraysbury and Reading — you will need a flood risk assessment, and the design will be shaped by minimum finished floor levels, flood-resilient construction and often compensatory storage. Basements are frequently ruled out.
Yes, subject to the disproportionate-addition test measured against the original dwelling. Most of the Royal Borough of Windsor and Maidenhead outside the towns is Metropolitan Green Belt, and prior extensions count against the allowance.
If the building is listed, yes, and they are separate applications. Listed building consent carries no statutory fee, but it requires a heritage statement and a fuller level of drawn detail than a planning application alone.
The same fixed fees as London: £840 for the Essentials planning package, £1,225 for a loft, £1,575 for a mansard or roof rebuild, and £1,750 for planning plus building regulations produced from one survey.
