The property boundary is the legal boundary of your plot — the line that separates your property from your neighbours’ or from public land. The property boundary is recorded in the Land Registry and determines where you may build, how high your fence can be and what rights and obligations you have towards your neighbours.
Property boundary and building
| Rule | Condition |
|---|---|
| Building on the boundary | Only with written permission from the neighbour |
| Fence on the boundary | Max 2 metres high (rear garden), costs shared |
| Distance to boundary | Permitted development outbuilding: may be built up to the boundary (rear garden) |
| Windows in side wall | Not within 2 metres of the boundary (neighbour privacy) |
Determining the property boundary
The property boundary is recorded in the Land Registry:
- Cadastral map — Can be consulted online via the Land Registry website
- Cadastral survey — A surveyor can mark the exact boundary with stakes
- Title deed — Your purchase deed contains the cadastral reference number
> Tip: If there is any doubt about the property boundary (for example with a fence or outbuilding): have a cadastral survey done. This prevents a dispute with the neighbours that costs far more than the survey.
