Overview
If you are planning to build a new wall at or near the boundary, the Party Wall etc. Act 1996 may apply. The process depends on whether the wall is to be built wholly on your own land, up to the line of junction, or astride the boundary as a party wall.
The key is to understand the project early, speak to your neighbour and serve the correct line of junction notice where required.
1. Understand your project early
Ask yourself:
- Are you building a new wall up to the boundary, but wholly on your own land?
- Are you asking to build a new party wall astride the boundary?
- Are foundations, projections or access likely to affect the neighbour's land?
If the Act applies, a line of junction notice must usually be served at least one month before the intended start date.
A wall built astride the boundary requires the adjoining owner's written consent. If consent is not given, the building owner cannot force an astride wall and will usually need to build wholly on their own land.
2. Communicate early and clearly
Before serving a formal notice, speak to your neighbour. Explain what you want to build, why it is needed and how disruption will be managed.
Drawings, sketches and simple visual aids can make a significant difference. Many neighbours object because they do not understand what is proposed.
3. Serve the correct notice
The notice should clearly describe the proposed wall and state the intended start date. It should also include the building owner's details and should be served correctly.
Common methods include personal service, post with proof of posting, or email where the receiving owner has agreed to receive notices by email.
Keep a clear record of how and when the notice was served.
4. Wait for the response
The adjoining owner can respond in different ways, depending on the type of wall proposed.
They may:
- consent to the proposed work;
- refuse consent to a wall astride the boundary;
- raise concerns or ask for clarification;
- serve a counter-notice where the Act allows it;
- dissent, where a dispute arises under the Act.
5. Address concerns and amend plans if sensible
Your neighbour may have reasonable concerns about design, access, drainage, future maintenance or disruption.
Where reasonable, consider small adjustments in return for written consent. That can be cheaper and faster than allowing the matter to become a formal dispute.
6. Formalise consent
If consent is given, obtain it in writing and keep it with your project documents.
If there is a dispute under the Act, surveyor appointments may be required and an award may need to be agreed or made before the relevant works proceed.
7. Consider an agreed surveyor
Where surveyors are needed, propose a single agreed surveyor. This is usually faster and cheaper than having two surveyors, and in many cases the outcome will be no different.
Separate surveyors are a legal option, but they often increase cost without improving protection.
8. Follow the award where one is required
If an award is needed, it should set out the relevant works, timing, access, protection measures and responsibility for costs.
Once it is in place, follow it carefully.
9. Keep the neighbour updated
Tell your neighbour when work is due to start and keep them informed if dates change. Respond quickly to concerns during the work.
Example timeline
- Initial discussion: ideally 1 to 2 months before serving notice.
- Serve notice: at least one month before the intended start date.
- Response period: usually 14 days from service.
- Dispute resolution: appoint surveyor or surveyors if required.
- award: issued once the surveyor or surveyors have agreed the relevant terms.
Conclusion
Getting consent for a boundary wall is usually about clarity and confidence. Explain the work early, serve the correct notice, keep records and offer reasonable assurances. That gives the best chance of keeping the process quick, compliant and neighbourly.
