Why do I need an OS map for my planning application?

When a planning application is submitted for a new property or development, the local authorities will almost certainly want planning maps to back up each request. It is critical that you use the correct type of map, or your application may be delayed or denied. They should cover a variety of topics related to the development and should make use of data from current Ordnance Survey maps. If you have never submitted a planning application before, you must ensure that you cover all areas before submitting your ideas.

Planning maps are an essential element of the process. The most typical reasons for applications being denied by local governments include incorrectly scaled, unauthorised, wrongly displayed, or out-of-date plans. The maps will make it obvious to the relevant local authority which land the application refers to. Ordnance Survey maps are constantly updated and have the correct format needed for your planning application.

How can I get an OS map for my planning application?

All planning applications, whether for a single house or an entire housing estate, require a map called a ‘Location Plan’ that shows the proposal in its surrounding context. Some local governments may also need a ‘Block Plan’ (sometimes known as a ‘Site Plan’), which specifies the development on a wider scale but not always in greater detail. These can be purchased directly from our site and hold all necessary information needed for your application including a scale bar, north arrow and licence.

How can I make sure that my OS planning application maps are valid?

When creating maps for planning applications, keep a checklist of all necessary items on hand. This will ensure that nothing is overlooked and will make your application run more smoothly.

Location Plans

A standard scale should be chosen which is commonly 1:1250 Plan for urban applications and 1:2500 Plan for bigger developments and those in rural areas. A planning map must have north clearly highlighted and should fit on a sheet of A3 or A4 paper. The map may indicate the date of the survey but must include the Ordnance Survey licence number, as well as the date it was purchased. Essential buildings and roads should be included, and the site border should be highlighted in red. This must include any acreage needed for access to the site. A blue line should be drawn around any land owned by the applicant that is next to or close to the proposed site.

Site Plans

Site (or ‘Block Plan’) must also be developed at the appropriate scale. This is usually done at a scale of 1:200 Plan or 1:500 Plan. The proposed development should be fully visible including the site boundary and any existing structures on the property. A north arrow, scale and scale bar should also be visible and clearly displayed. Site Plans must incorporate a variety of information unless they will not be affected or influenced by the proposed plans. They should include any footpaths, roads, and buildings on the next property, as well as the access arrangements. Any public rights of way adjacent to or across the site, as well as all trees in existence, should be indicated. The plans must show the type and extent of the hard surfacing, as well as the type and location of any borders that will be employed, such as fencing or walls.

Are OS planning maps free?

There is a fee that must be paid for all OS planning maps. As suppliers we pay the Ordnance Survey for the use of their data and the Ordnance Survey is continuously surveying and making sure that the maps provided are up to date and detailed enough to cover the UK which in turn costs enough money.

What kind of OS maps do I need for my planning application?

A large-scale planning application map must be obtained from one of Ordnance Survey's official suppliers like BuyAPlan®. When evaluating a planning application that contains an OS map, the local authority may request confirmation that the usage of the mapping data is correctly licensed by the Ordnance Survey so you will need to make sure that your plan is valid and purchased from an official OS partner.

What should be included in my OS planning maps?

All planning maps must include the proposed development in respect to the site boundaries, as well as written dimensions. It should take into account any public rights of way, trees, hard surfacing, and border treatment (where applicable). They should also feature a prominent North arrow and OS licence number as well as the scale and scale bar.

How long does my OS planning map’s licence last for?

Ordnance Survey map data is not for sale; instead, it is licenced through suppliers such as BuyAPlan®. Any digital mapping you purchase through BuyAPlan® is licenced for one year. If you need for the license to last longer, please contact us.

How accurate are OS planning maps?

We use OS MasterMap® to create our planning maps. OS MasterMap® provides the most complete and accurate representation of the landscape in the United Kingdom. It contains man-made and natural environment features such as roads, tracks, and walkways, land cover, buildings, water features, railways, height information, heritage features and structures and administrative boundaries. It gets updated every 6 weeks but the currency of the map depends on when a survey has taken place and then added to the map. The Ordnance Survey can give precise details of when a location was last updated.

What scales are used by the OS?

The main surveying scales used by the Ordnance Survey (OS) are 1:1250 Plan, 1:2500 Plan, and 1:10000. These are known as large scale maps, which depict real-world things in greater detail on the map. OS also produces a variety of mapping products at different scales, including 1:25 000 and 1:50 000. OS MasterMap® is designed for display in urban, rural, and mountain/moorland areas at 1:1250, 1:2500, and 1:10000 scales.

What can OS maps be used for?

The accuracy and detail of OS maps provides the assurance you need to make location-based decisions about assets, services, environmental concerns and various operations. OS maps can be used for several purposes including for: planning applications, cartographic representation of areas, property development, route planning, land management, finding a site’s access points, risk assessment, environmental monitoring and geographical analysis and tourism.
