Searching a council planning register properly

Every local planning authority in England keeps a public register of planning applications, and any search of planning register history has to start there. The duty comes from section 69 of the Town and Country Planning Act 1990, with the detail set out in article 40 of the Development Management Procedure Order 2015. The council's online portal is a search front end to that register. It is not the register itself, and the gap between the two catches people out constantly.

So before you decide a site has no planning history, work out what you have actually searched.

What the register holds, and what it leaves out

The register records each application by reference number, the address, a description of the proposed development, the date of receipt, the decision and the date of that decision. Alongside it councils publish the application forms, submitted drawings, consultee responses, neighbour representations and the officer report or delegated report. The decision notice lists the approved drawing numbers and every condition.

A separate register of enforcement notices and stop notices sits under the same Order. Plenty of portals put it behind a different search box, or leave it off the public site altogether, so a site with a live enforcement history can look clean on the main application search. If you are tracing a breach rather than a permission, read how council enforcement priorities and complaints are handled before drawing conclusions from silence.

Section 106 agreements usually appear as a scanned deed, sometimes only after completion, and sometimes filed against the parent outline permission rather than the reserved matters approval that triggered the payment. Compliance correspondence and section 106 monitoring fee records are almost never published.

Four categories routinely sit outside the register: building regulations approvals, highway agreements, licensing decisions, and works that never needed permission at all. Lawful permitted development leaves no trace unless the owner applied for a prior approval or a lawful development certificate.

Searching by address, reference and map

Address search is the least reliable route. Property descriptions on older records were typed by hand, so "Land rear of 14 Mill Lane" will not surface from a search for "14 Mill Lane", and a house that was once two cottages may appear under both former addresses. Search the street name on its own, then filter by date. It returns noise, but it returns the thing you are looking for.

Reference numbers follow local conventions rather than a national one. Most take the form of a year, a sequence number and a suffix for the application type, so once you have one reference for a site you can often guess the shape of its siblings. Search on the numeric stem without the suffix where the portal allows it.

The map search is the one worth learning properly. It plots the red line boundary of each application rather than the postal address, which is how you find applications on land behind, beside or beneath a property. Drag the search area wide, set the date range to the maximum, and include withdrawn and refused decisions. Refusals matter more than approvals when you are judging what an officer will accept.

Records that predate the portal

Development control in its current form began on 1 July 1948 under the Town and Country Planning Act 1947. Anything built before that date needed no planning permission, so the absence of a record is not evidence of a breach. For buildings of that age the useful documents are rating records, Ordnance Survey editions and deeds rather than the planning register.

Between 1948 and the mid-1970s the decision-making authority was often the county council, and the files may now be in the county record office rather than the district's. After local government reorganisation, boundary changes left some files with the wrong successor authority.

Online coverage typically starts somewhere between 1996 and 2005, depending on when the council scanned its back catalogue. Earlier applications may exist as an index card entry with no drawings attached. Microfiche survives in some authorities. A register entry that shows a reference and a decision date but has no documents tab is a signal that the paper file still exists somewhere.

Reading the documents in the right order

Portals list documents by upload date, which is close to useless. Read them in this order instead.

1. The decision notice, for the outcome, the conditions and the list of approved drawings.
2. The officer report, for the policies applied and the balance struck.
3. Consultee responses from the highway authority, the lead local flood authority and any statutory body, because these constrain what a later application can propose.
4. Neighbour representations, for the local issues that will resurface.
5. The drawings, checked against the approved list on the decision notice rather than against what looks most recent.

That last point matters. Superseded drawings stay on the portal, and a revision uploaded during determination may never have been approved. If the decision notice names drawing 1042-P-03 Rev B, revision C on the documents tab is not permitted development, whatever its date.

Following the chain of related applications

Sites accumulate applications. An outline permission generates reserved matters approvals, each of which generates condition discharge applications. A section 73 application varies a condition and produces a fresh permission with its own reference, while the original permission survives alongside it. Section 96A non-material amendments sit on top of all of it.

The practical consequence is that the operative permission for a site is rarely the one with the most recent date. Build the chain backwards from the newest reference, noting at each step which permission is being varied or discharged, until you reach the grant that created the development rights. Then check whether that grant was implemented in time.

Where a site straddles a designation or a plan allocation, the chain also tells you which policy framework each decision was taken under. A refusal from 2017 was decided against a different Framework and probably a different local plan, which is why it pays to check whether a neighbourhood plan covers the site and when it was made.

Keeping watch on a site

Most portals offer a tracking function that emails you when a document is added or a decision is issued. Register for it on the specific reference rather than relying on the weekly list, because weekly lists are published by ward or parish and an application on the far side of a boundary will not appear in yours.

Weekly and monthly lists are still worth subscribing to for the surrounding area. They are the only routine way to see pre-application enquiries announced, where a council publishes them, and they catch applications whose site address bears no relation to the land you care about.

And set a diary reminder for the end of the consultation period rather than the start. Representations submitted after the officer has drafted the report carry less weight, even when the formal period is still open.

Asking for what is not published

Where a document is missing, the planning register is not the only route. Planning information is environmental information, so a request under the Environmental Information Regulations 2004 reaches material that the portal does not carry, including older files, internal consultation responses and correspondence. The authority has 20 working days to respond and can charge only reasonable costs for copying, not for staff time spent searching.

Viability appraisals, pre-application advice and legal advice are the three categories most often withheld. Viability material submitted after 2018 is generally expected to be public, and a refusal to disclose should be tested rather than accepted.

If the file is paper only, ask for an inspection appointment instead of copies. It is faster, and you see the whole file rather than the pages someone else selected.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it. Once you know what the site's history allows, enter your postcode on PlanScope to see which reports a new application there is likely to need, or browse the full list of report types.
