Finding and reading a local plan policies map online

The local plan policies map online is the document that tells you which of your council's planning policies apply to your land. Search your council's website for adopted policies map rather than for local plan, because the plan itself usually does not contain the map, and the two are published separately.

Ten minutes with it will tell you whether you are inside the settlement boundary, whether your garden is in a conservation area, whether the field behind you is allocated for housing, and whether an Article 4 direction has removed the permitted development right you were relying on. Those are the four facts that most often change a householder application after it has been drawn.

Where the map lives and how it is published

Under the Local Planning Regulations 2012 the policies map is published with the adopted plan and illustrates geographically where the plan's policies apply. It is not itself a policy document, which is a distinction worth holding onto: the policy wording governs, and the map shows the extent.

In practice you will find one of three things. A set of PDF sheets, sometimes a strategic sheet plus insets. An interactive map viewer with layers you can switch on and off. Or increasingly, datasets published to a national standard and available through the planning data service alongside the council's own version.

Older plans call it the proposals map. Some authorities have a current policies map assembled from more than one plan. Where that is the case the council usually publishes a note explaining which designations come from which document, and read it before you open the map.

Designations you should check first

Work through these in order, because the earlier ones change what the later ones mean.

• Settlement boundary or development limit. Inside or outside is the single most consequential line on the map for anything beyond an extension.
• Site allocations, both on your land and adjoining it.
• Conservation area, and whether any Article 4 direction applies within it.
• Listed buildings on or next to the site, including the curtilage question.
• Green Belt, National Landscape, National Park.
• Flood zone, and any critical drainage area or surface water designation the council shows.
• Tree Preservation Orders, where the council maps them.
• Local Green Space, open space, playing field and allotment designations.
• Employment area, town centre boundary, primary shopping area.
• Air quality management area.

For a householder application the conservation area line and any Article 4 direction do most of the work, because together they decide whether you need permission at all. For anything larger, the settlement boundary and the allocations decide the principle.

Allocations and what they mean for neighbours

An allocation is the plan saying a site is expected to come forward for a particular use. It is not a permission, and it does not fix the layout.

If a site next to you is allocated, three things follow. The principle of development there has been established through the plan process, so objecting to the principle at application stage carries little weight. The allocation will usually have a policy attached setting out requirements such as access arrangements, open space or a maximum number of units, and that policy is where the useful objection material sits. And the supporting text in the plan often records constraints the applicant has to address.

Read the allocation policy and its justification rather than just noting the hatching on the map. As an illustrative example, an allocation for around 40 dwellings with a policy requiring vehicular access from a named road and retention of a boundary hedgerow gives a neighbour two specific tests to hold an application against, which is far more effective than a general objection about traffic.

Inset maps and their scale

Use the largest scale sheet available. A strategic sheet covering a whole district at 1:25,000 is for orientation, not for boundaries, and a line 0.5 mm wide on that sheet is over ten metres on the ground.

Insets exist for exactly this reason, usually for each town and larger village. Check whether your site appears on an inset and use that version. Where the strategic sheet and the inset appear to differ, the inset normally governs, and the council should confirm it.

Two further cautions. A scanned PDF of a map originally drawn on paper carries registration errors that nobody has corrected. And an interactive viewer that lets you zoom to a metre gives an impression of precision the underlying data does not have.

So where your site sits on or close to a boundary, email the planning policy team, attach a site plan, and ask them to confirm in writing which side of the line the site falls. Keep the reply and submit it with the application. Officers change, and a written confirmation is the only thing that travels.

Saved policies from an older plan

Many authorities are working with a patchwork. A recent plan covering strategy and housing numbers, plus saved policies from a predecessor plan covering design detail, parking standards and local designations.

The practical consequence is that a policy number quoted in a decision notice may not appear in the document you downloaded. Look for the council's list of saved policies, which is usually published with the adopted plan, and check it before you assume a policy has gone.

Neighbourhood plans add another layer. Where one has been made, it forms part of the development plan for that area and has its own policies map. Those maps are often the most detailed available, and they frequently designate Local Green Space and important views that the district map does not show.

Emerging plan maps and their weight

An emerging plan can carry weight in decisions, and how much depends on three things the Framework identifies: the stage the plan has reached, the extent of unresolved objections to the relevant policies, and the degree of consistency with national policy.

So check the emerging map as well as the adopted one. A site allocated in a plan at examination is in a different position from the same site in a plan at first consultation. And a designation proposed over your land in an emerging plan is worth objecting to now rather than arguing about later.

Cross-check anything environmental against the national sources rather than relying on the council's layer alone. The flood map for planning gives the Environment Agency position, the environmental mapping service gives designations such as sites of special scientific interest and ancient woodland, and the watercourse question needs its own check because checking whether a watercourse is a main river determines who regulates work near it. Rights of way are a separate register again, and the definitive map for public rights of way is held by the county or unitary authority rather than shown reliably on a policies map.

Printing an extract for your application

You need two plans for an application and the policies map is not one of them. The location plan and the site plan have to come from a licensed source, because council maps are published under mapping licences that do not permit reuse in your own documents.

What the policies map gives you is the content of your supporting statement. Use it to write a short paragraph listing every designation affecting the site, with the policy reference for each, and to work out which technical reports you need. A site in Flood Zone 2 needs a Flood Risk Assessment. A site in a conservation area or affecting a listed building needs a Heritage Statement.

Then screenshot the relevant inset for your own file, with the date you looked, and note the plan it came from. Designations change on adoption of a new plan, and a record of what applied on the day you designed the scheme is useful if the plan moves while your application is running.

Enter your postcode on PlanScope to see which reports the designations on your site are likely to trigger.
