Completion of a P24 Check Survey by the OS

General

The P24 forms are sent electronically to the OS by MBM. On receipt the OS will allocate the job to a home based surveyor who will check all the information and documentation to ensure that the requisition can be complied with. The OS agree to make every effort to complete the survey within 15 working days of receipt. However if it is an expedite survey, they will attempt to complete the survey within 5 working days.
On completion, the P24 form is emailed back to MBM together with any supporting photos, etc provided by the surveyor. OS Customer Services in Southampton will supply the new map detail as part of our regular supply of new or updated map data. Once this is received and available on the Plan Viewer, etc., MBM will return the P24 and relevant documentation to the submitting officer.

The Ordnance Survey (OS) is able to provide the following information when responding to a P24 Check Survey request:

Age, nature and height of boundary features

In addition to enquiries about specific boundary features, the surveyor will automatically supply this information where an existing feature is shown in a new position or a new feature is shown near to one which is removed. Some points to note:

An approximation is usually sufficient for height and thickness.
The age, which will also usually be approximate, will be assessed from the materials used, surrounding structures, condition (not reliable), state of ground and vegetation, and, in the case of hedges, the size of stems or trunks.
The nature of a boundary feature will be given by a concise written description. For example, if a boundary follows a geographical feature, such as slopes or cliff, the surveyor will annotate it ‘property boundary’ in pencil on the sketch or overlay trace.

Nature and use of land

A brief statement of the use, and the nature of vegetation or other surface is usually sufficient. Changes in surface detail may be important.

Extent of occupation

This may be as observed by the surveyor, using the following as an indication:

the extent of a particular area of land; or
the floor overlaps within a building; or
which property appears to be occupying a piece of land.

Means of access

All points of access will be indicated together with:

a description of any gates or doors;
whether they are lockable; and
where there is any indication, who is the keyholder.

Evidence of former boundary features

Examples of these are: old fence posts, hedge stumps, foundations of buildings, and so on.

Horizontal ground measurements

These will be the non-equated actual site measurements in metres to one decimal place between specified points of detail, or alternative relevant measurements if the surveyor is unable to identify the points specified. Measurements will be horizontal and will be taken from the centre line of features or external corners of buildings and their start and finish will be clearly indicated.

Other additional information

This will be collected at the site by observation or by local enquiry. For example, name and address of information providers, a short summary of any significant conversations or statements by any party concerning occupation and use of land, alleged ownership or dispute, or changes to boundaries, displayed notices that may be relevant, and so on.

Photographs may be supplied if requested; they will be supplied in JPEG with the completed P24. On occasion the surveyor may provide photographs at his/her discretion where it is felt this will be beneficial. The Ordnance Survey can provide ad-hoc prints to scale (usually at the surveyor’s discretion) when requested to show the position of non-specification detail i.e. driveways, paths etc.

If the survey requires access to a property to check internal divisions and/or floor levels or you are aware of any access problems, a contact telephone number and name must be provided, before sending to MBM. If you are aware of any unresolved dispute this must also be noted on the survey requisition.
