The Party Wall etc. Act 1996 is one of the most misunderstood pieces of legislation in English property law. Every year, we see homeowners in Crowborough and across East Sussex start building projects without complying with it — and then face injunctions, neighbour disputes and costly delays as a result. This guide explains the Act clearly, in plain English, so you know exactly what you need to do before building work starts.
What Is the Party Wall etc. Act 1996?
The Party Wall etc. Act 1996 is a piece of legislation that applies in England and Wales. It sets out a framework for preventing and resolving disputes between neighbours when one of them wants to carry out building work that affects a shared wall, floor or boundary structure.
The Act requires the person doing the work — called the building owner — to give formal advance notice to their neighbours — called adjoining owners — before certain types of work begin. It also provides a mechanism for resolving disputes if the adjoining owner objects to the work.
Crucially, the Act does not stop you from carrying out work. It simply requires that your neighbours are properly informed and that their interests are protected.
When Does the Party Wall Act Apply?
The Act applies in three main scenarios:
1. Work on an Existing Party Wall or Party Structure
If you want to carry out work to a wall or structure shared with a neighbour — such as cutting into it to install a beam, raising its height, or underpinning it — the Act applies. This is covered under Section 2 of the Act and is the most common scenario we deal with at Crowborough Surveyor.
Examples include: building a loft conversion that involves raising or modifying the party wall, inserting steelwork into a shared gable wall, and repairing or rebuilding a shared wall.
2. Building a New Wall Astride the Boundary
If you want to build a new wall on the line of the boundary between your property and a neighbour's, Section 1 of the Act applies. You must serve notice at least one month before work is planned to start.
3. Excavation Near Neighbouring Buildings
If you plan to excavate within three metres of a neighbouring building or structure to a depth lower than its foundations, Section 6 applies. This is particularly relevant for basement extensions or deep foundation work. You must serve notice at least one month before work starts.
What Is a Party Wall Notice?
A party wall notice is a formal written document served on your neighbours before work begins. It must include:
- Your name and address (as building owner)
- The address of the property where the work is to be carried out
- A full description of the proposed works
- The proposed start date
- A statement that it is a notice under the Party Wall etc. Act 1996
For most party wall works, notice must be served at least two months before the intended start date. For excavation works under Section 6, one month's notice is sufficient.
"We started building our rear extension before properly serving notice — we didn't realise it was required. Our neighbour took legal advice, and we found ourselves facing an injunction. The delay cost us over £3,000 in contractor standing time alone. We wished we'd called Crowborough Surveyor at the start."
What Happens After You Serve a Party Wall Notice?
Once you serve notice, your neighbour has 14 days to respond. They can:
- Consent in writing — the simplest outcome. Work can proceed, though a Schedule of Condition is still advisable to protect you against future damage claims.
- Dissent and agree to appoint an Agreed Surveyor — both parties agree to use the same party wall surveyor (typically the most cost-effective route).
- Dissent and appoint their own surveyor — in which case you must also appoint a surveyor, and the two surveyors together (or a Third Surveyor if they cannot agree) will draw up a Party Wall Award.
- Fail to respond within 14 days — this is treated as a deemed dissent, triggering the surveyor appointment process.
What Is a Party Wall Award?
A Party Wall Award (sometimes called a Party Wall Agreement, though this is technically incorrect) is a legally binding document drawn up by the appointed party wall surveyor(s). It sets out:
- The works to be carried out and in what manner
- The hours during which work may take place
- A Schedule of Condition of the adjoining owner's property (to record its state before works begin)
- Access rights and security provisions
- The procedure for making good any damage caused by the works
Once the Award is served on both parties, works covered by it can lawfully proceed. The Award also provides a clear baseline against which any damage claims can be assessed — protecting both the building owner and the adjoining owner.
Who Pays the Party Wall Surveyor's Fees?
As the building owner — the person doing the work — you are generally responsible for the costs of the party wall process. This includes the fees of any surveyor appointed by your neighbour, as well as your own surveyor's fees. This is an important point: if your neighbour appoints their own surveyor, you'll be paying for both.
This is why we always encourage clients to appoint an Agreed Surveyor where possible — a single surveyor acceptable to both parties who can produce the Award efficiently and cost-effectively. At Crowborough Surveyor, we act as Agreed Surveyor regularly and this is by far the most straightforward route for straightforward projects.
Do I Need a Party Wall Surveyor for a Loft Conversion in Crowborough?
Almost certainly yes, if your property is a semi-detached or terraced house. Loft conversions typically involve:
- Raising the height of the party wall (triggers Section 2)
- Inserting steel beams into the party wall (triggers Section 2)
- Work within the roof space of a semi-detached or terraced property (may trigger Section 2)

What About Garden Walls and Boundary Fences?
Not all boundary structures are covered by the Party Wall Act. Free-standing garden walls and timber fences are generally not party structures under the Act, unless they form part of the structure of a building. However, if you plan to build a new wall on or near the boundary, Section 1 may apply. Again, the safest course is to seek advice before proceeding. We're happy to advise — get in touch.
Party Wall FAQs
No. The Party Wall Act does not give neighbours the right to veto your building work. It gives them the right to be informed and to have their interests protected. Even if your neighbour dissents, work can lawfully proceed once an Award is in place.
Your neighbour can apply to the court for an injunction to stop the works. They can also pursue damages for any loss or inconvenience caused. Starting without notice is a serious mistake — we've seen it cost homeowners tens of thousands of pounds in delays, legal fees and compensation.
In simple cases where both parties co-operate, the process can be completed in 6–8 weeks from serving notice. More complex projects or disputed matters can take longer. We always advise clients to factor party wall timing into their build programme from the outset.
A Schedule of Condition is a photographic and written record of the state of the adjoining owner's property before building works begin. It protects both parties — the adjoining owner can use it to demonstrate any damage caused by the works, while the building owner can use it to dispute inflated claims. We always recommend one, even when the adjoining owner has consented.
