Most property owners have seen their title plan. Fewer have really understood it.
That red line around your property looks straightforward enough. But title plans contain more information than most people realise — and some significant limitations that aren't obvious unless you know what to look for.
This guide explains how to read a title plan properly: what the various elements mean, what the plan can tell you, and where its limitations lie.
What is a Title Plan?
When land is registered with HM Land Registry, two documents are created: the register (a text document describing the property and any rights or restrictions) and the title plan (a map showing the extent of the registered land).
The title plan is based on Ordnance Survey mapping. The Land Registry takes the OS base map and adds edging — typically red — to show the land included in the title.
Every registered property in England and Wales has a title plan. You can download yours from the Land Registry for £7.
The Elements of a Title Plan
The base map
The underlying map is Ordnance Survey data — the same mapping that covers the entire country. Depending on when your title was created and the type of area, this might be at different scales:
- 1:1,250 — Urban areas, showing individual buildings and features in detail
- 1:2,500 — Rural areas, showing field boundaries, buildings, and major features
- 1:10,000 — Remote or mountainous areas, showing less detail
The scale is shown on the plan, usually in the corner or margin.
The OS base map shows physical features as they existed when the mapping was captured — buildings, roads, fences, hedges, water features, and so on. This mapping is periodically updated, but there's often a lag between changes on the ground and changes on the map.
The red edging
The red line around the property — technically called “the extent” — shows the land included in the title. This is what most people focus on.
This is the “general boundaries rule” that applies to almost all registered land in England and Wales. The red line indicates approximately where the boundary lies, usually by reference to physical features shown on the map. It doesn't fix the precise boundary line.
The actual legal boundary might be:
- Along one side of a feature (the hedge, not the middle of the hedge)
- In a position that's changed since the map was made
- Defined by the original conveyance in terms that don't exactly match the map
The title plan identifies the land. It doesn't survey it.
Blue edging
Blue edging typically indicates land that affects the title but isn't part of it — for example:
- Land over which you have a right of way
- Land that benefits from a restriction on your property
- Land referenced in an easement
Check the register to understand what any blue edging means in your specific case.
Green edging
Green edging is less common but usually indicates land affected by a specific entry in the register — for example, land subject to a particular restriction or covenant.
Again, the register explains what it means.
Tinting
Sometimes areas are tinted (coloured in) rather than just edged:
- Red tinting often indicates the extent of a lease within a larger building
- Blue or green tinting may indicate specific areas referenced in the register
Tinting is particularly common for flats and commercial units within larger buildings, where edging alone wouldn't clearly show which parts are included.
Reference numbers and letters
Title plans often include numbered or lettered points referenced in the register. For example:
- “The land has the benefit of a right of way between the points marked A and B on the title plan”
- “The area marked 1 on the plan is subject to...”
These references connect the visual plan to the verbal descriptions in the register.
What the Plan Can Tell You
A title plan reliably tells you:
The general extent of the property
Which land is included in your title, in broad terms. You can see whether a particular building, garden area, or field is part of your registered ownership.
The relationship to surrounding features
How your land relates to roads, neighbouring buildings, watercourses, and other features. This context helps identify the property on the ground.
The scale and orientation
How big the land is (approximately) and which way is north. Title plans always include a scale bar and north arrow.
Whether there are additional complexities
Blue or green edging, tinted areas, and reference points indicate that there's more to understand. They prompt you to read the register carefully.
What the Plan Cannot Tell You
The exact boundary position
This is the big one. The title plan shows the general boundary, not the precise line. If you need to know exactly where your boundary lies — for building work, resolving a dispute, or establishing a fence line — the title plan alone isn't sufficient.
The exact boundary is determined by:
- The original conveyance or transfer that created it
- Physical features and their historical positions
- Relevant legal principles
Important
What's on the ground now
Title plans are based on OS mapping, which may be months or years out of date. New buildings, removed features, and changed boundaries won't appear until the mapping is updated.
The plan shows what the OS recorded, not necessarily what exists today.
Vertical extent
For freehold land, the title plan shows the horizontal extent — the land viewed from above. It doesn't explicitly show vertical extent (how far up or down your ownership goes).
For leasehold property, vertical extent matters more — which floors are included, whether you own the roof space or basement. Lease plans often include floor plans or verbal descriptions to clarify this.
Rights and restrictions
The title plan shows where land is. The register describes what rights exist over it. A right of way might cross your land, but you won't understand its terms from the plan alone — you need to read the register.
Accuracy of the underlying features
The OS mapping that forms the base of the title plan is accurate, but not perfect. Features are positioned within the accuracy limits of the survey method and scale. A feature shown as a line has real-world width; a building footprint might be slightly simplified.
For most purposes this doesn't matter. For precise boundary work, it might.
Common Misunderstandings
“The red line is my exact boundary”
No. The red line shows the general boundary by reference to mapped features. The exact legal boundary may differ.
“If the fence is inside the red line, I own the land up to the fence”
Not necessarily. The fence might have been moved since the title was registered. The legal boundary might be in a different position. Long occupation might have changed things. The relationship between the red line and physical features is indicative, not definitive.
“The title plan proves where my boundary is”
It's evidence, but not conclusive evidence. If there's a dispute, the title plan is one piece of information among several — including the original conveyance, historical maps, physical evidence, and potentially expert opinion.
“The Land Registry has surveyed my boundary”
The Land Registry doesn't survey boundaries. It records ownership based on submitted documents and OS mapping. The general boundaries rule explicitly avoids the Land Registry having to determine exact boundary positions.
When You Need More Than a Title Plan
A title plan is sufficient for:
- Understanding generally what you own
- Identifying your property for most purposes
- Checking whether specific features are within your title
A title plan is not sufficient for:
- Building near a boundary — You need to know the exact position, not the general area
- Boundary disputes — You need professional investigation of the actual boundary
- Development or subdivision — You need accurate survey data
- Determined boundary applications — You need a precise survey to fix the boundary line
In these situations, professional surveying adds the precision and investigation that title plans don't provide.
How to Get Your Title Plan
You can download your title plan from the Land Registry:
- Go to the Land Registry portal
- Search for your property by address or title number
- Purchase the title plan (currently £7)
You'll receive a PDF showing the plan with its red edging and any other relevant markings.
If you don't know your title number, you can search by address. The search will show all registered titles at that location.
Reading Between the Lines
Title plans reward careful reading. Here are some things to look for:
Boundary features that have changed
If the red edging follows a hedge shown on the map, but you know the hedge was removed and replaced with a fence in a different position, there may be a discrepancy between the registered extent and the physical position.
Complex boundaries
Boundaries that jog around buildings, follow irregular features, or have multiple small parcels may indicate historical complexity — perhaps a property assembled from several purchases, or land with a complicated history.
Reference points without obvious explanation
If the plan shows lettered points (A, B, C) but you can't immediately see what they relate to, check the register carefully. There may be rights, restrictions, or other matters that affect specific locations.
Different edging colours
Any colour other than red indicates something beyond the basic extent. Blue, green, or other colours always mean “check the register to understand this.”
Tinted areas
Tinting usually indicates parts of a building — relevant for flats, commercial units, or other situations where multiple titles exist within a single structure.
For most purposes, a title plan tells you what you need to know: which land is registered to which title, and how it relates to surrounding features. For precise work — building, boundary resolution, development — professional surveying provides the additional accuracy and investigation that title plans aren't designed to offer.
Understanding what your title plan can and cannot tell you is the first step to using it properly.
