Why prior approval rarely works in Slough
The numbers are blunt. In the latest published year the council granted 6 larger home extensions by prior approval and refused 43. Upward extensions were split evenly, with 1 granted and 1 refused.
A refusal rate that high means the prior approval route is risky for a deep rear extension in the town, and we say so before you pay for the application. Often a householder application, judged against the council's own guidance, is the safer course.
Our planning drawings in Slough are built for that route.

Slough's guidance and policy documents
The core planning documents are the Slough Local Development Framework Core Strategy 2006-2026 (with Site Allocations DPD and saved Local Plan for Slough policies), adopted in 2,008. They are long-standing documents, so we check whether any newer evidence or appeal decision has moved the council's thinking.
For household extensions the practical guide is the Residential Extensions Guidelines Supplementary Planning Document (RESPD). It is the document officers use to judge extensions to existing homes. We draw to it and mark the compliance points on the plans.
Householder decisions in Slough
The council decided 405 householder applications between July last year and June this year and granted 81 per cent. 81.5 per cent were decided within eight weeks or an agreed extension.
Minor applications, such as one or two new homes, were granted at 78.6 per cent, with 71.8 per cent decided on time.
These are historic figures for the town, useful for planning a programme but never a promise about one house.
Flats, leases and landlords in Slough
Permitted development does not apply to flats, so flat owners here almost always need an application, and often a landlord's licence as well. Where a block has a freeholder, their consent may be needed before work starts.
If you own a house and want to split it, our flat conversion drawings in Slough cover layout, parking and refuse storage. The council has no Article 4 direction for small HMOs, but a change of use still needs checking against the plan.
Heritage and Green Belt around Slough
The council publishes 5 conservation areas. Historic England lists 105 entries: 5 at Grade I, 7 at Grade II* and 92 at Grade II.
There are 4 registered parks and gardens and 2 scheduled monuments, with no entries on the Heritage at Risk Register. Around 27 per cent of the borough is Green Belt, which matters on the edges.
Prices, lawful development and levy in Slough
A terraced house averages £355,644, a semi-detached £457,835 and a flat £218,068. The twelve-month change to July was -1.8 per cent.
The council has no Community Infrastructure Levy. It received 157 lawful development certificate applications in the latest published year, a route our Lawful Development Certificate service covers for permitted work.
How a Slough job runs
You send the address, a few photographs if you have them, and a description of the change. Messages sent before three in the afternoon get a reply the same working day, and the first answer is the constraints check.
If an application is needed, we measure the property or use your survey, draw the existing and proposed layouts and prepare the location and block plans, which are free inside a planning package. Drawings take about seven days after the survey.
Another chartered technologist checks the set before submission. If the council asks for amendments, we redraw without charge until the application is decided.
