Party Wall Notices: What to Serve, 14-Day Response Rules, Counter-Notices and Agreed Award Format
Quick Answer: Under the Party Wall etc. Act 1996 you must serve written notice on the adjoining owner before certain works. The three notices are: Line of Junction notice (Section 1) for a new wall at the boundary — 1 month before work; Party Structure notice (Section 2) for work to an existing party wall — 2 months before work; and Notice of Adjacent Excavation (Section 6) for digging within 3m (or 6m for deeper foundations) of a neighbour's structure — 1 month before work. The adjoining owner has 14 days to respond; if they dissent, do not respond, or you receive silence, a dispute is deemed to arise and surveyors must agree a Party Wall Award before work starts. The Act is a civil statute, not Building Control — it runs in parallel with Building Regs and planning.
Summary
The Party Wall etc. Act 1996 sits between you and your neighbour, not between you and the council. It is a piece of civil law that gives a "building owner" (the one doing the work) a right to carry out specified works affecting a shared or boundary structure — provided they first notify the "adjoining owner" and follow the dispute-resolution process if there is any objection. It is completely separate from Building Regulations and planning permission: you can have full planning consent and a Building Control sign-off and still be acting unlawfully if you skipped a party wall notice.
The procedure is built around three notices and one clock. The notice you serve depends on the work: a new wall on the boundary (Section 1), works to or into an existing party wall such as cutting in a beam, raising it, or underpinning (Section 2), or excavating close to a neighbour's foundations (Section 6). Once served, the adjoining owner has 14 days to consent or dissent. The trap most tradespeople fall into is assuming silence means "yes." It does not — silence after 14 days is treated as dissent, which puts you into the surveyor/Award process whether you like it or not.
For the working builder this matters commercially. Serving notice too late delays the start date (you cannot begin Section 2 work for 2 months); serving an invalid notice (wrong owner, missing detail, no signature) means it does not count and any work is a trespass exposing you to an injunction. This article gives you the practical flow, the response rules, the counter-notice option, and ready-to-adapt notice templates.

Key Facts
- Party Wall etc. Act 1996 — applies in England and Wales (not Scotland or Northern Ireland, which have different boundary law).
- Building owner — the person carrying out (or wanting to carry out) the works.
- Adjoining owner — the neighbour whose wall/structure/land is affected; includes freeholders and leaseholders with leases over a certain length, so multiple notices may be needed for one property.
- Section 1 — Line of Junction notice — building a new wall at or astride the boundary line. Notice period 1 month before work begins.
- Section 2 — Party Structure notice — works to an existing party wall or structure: cutting in beams, inserting a DPC, raising or underpinning the wall, removing chimney breasts on the party wall, demolition and rebuild. Notice period 2 months before work begins.
- Section 6 — Notice of Adjacent Excavation — excavating within 3 metres of a neighbouring structure where you will dig deeper than its foundations, or within 6 metres where your excavation falls within a 45° line drawn down from the bottom of the neighbour's foundations. Notice period 1 month before work begins.
- 14-day response window — the adjoining owner has 14 days from service to respond.
- Consent in writing → you may proceed (subject to the notice period) without surveyors; a Schedule of Condition is still strongly advised.
- Dissent → a dispute is deemed to arise; surveyor(s) appointed and a Party Wall Award is required before work.
- Silence (no response in 14 days) → deemed dispute — same outcome as dissent. The Act forces the surveyor process.
- Counter-notice (Section 4) — within 1 month of a Party Structure notice, the adjoining owner can serve a counter-notice requiring the building owner to include additional/related works (e.g. extra height, chimney provisions) for the adjoining owner's benefit, at the adjoining owner's expense.
- Surveyors — either a single "Agreed Surveyor" acting impartially for both, or two surveyors (one each) who jointly select a Third Surveyor to resolve any deadlock.
- Party Wall Award — the binding document recording the agreed works, working hours, access, a Schedule of Condition (photographic record before work), and who pays. Either party can appeal to the County Court within 14 days of service of the Award.
- Who pays the surveyors — generally the building owner pays the reasonable surveyor fees, as the party benefiting from the works.
- Not Building Control — the Act is a private civil matter; no council enforcement. Breach is enforced by the neighbour through the courts (e.g. injunction).
- No retrospective notice — you cannot validly serve notice after starting work; start without a valid notice and the work is a trespass.

Detailed Guidance
Step 1 — Identify the right notice (and the right owners)
Work out which section the works fall under — you may need more than one notice (e.g. an extension with a new boundary wall and excavation near the neighbour triggers both Section 1 and Section 6). Then identify every adjoining owner: that means freeholders and any leaseholders with a sufficiently long lease, on each affected neighbouring property. Serving the wrong person, or missing a leaseholder, invalidates the notice.
Step 2 — Serve a valid notice
A valid notice must include the building owner's name and address, the address of the building, a description of the proposed work (with plans/sections for excavation), the proposed start date (no earlier than the notice period), and be signed and dated. Serve it by hand, by post, or by email only if the adjoining owner has agreed to electronic service. Keep proof of service.
Step 3 — The 14-day clock
From the date of service the adjoining owner has 14 days to respond:
- Written consent → you wait out the notice period (1 or 2 months) then proceed. Even with consent, take a dated photographic Schedule of Condition of the neighbour's property to protect yourself against later damage claims.
- Dissent → a dispute is deemed to arise.
- No response in 14 days → the Act deems a dispute. (Best practice: serve a "10-day letter" reminder if you hear nothing, but the dispute is still deemed.)
Step 4 — Counter-notice (Section 4)
If you served a Party Structure (Section 2) notice, the adjoining owner may, within 1 month, serve a counter-notice asking you to carry out additional related works for their benefit — for example building the wall higher or thicker, or providing for their chimney/flue. You must comply so far as it is reasonable, but the adjoining owner pays the extra cost of works done solely for their benefit.
Step 5 — Surveyors and the Award
Where a dispute is deemed, the parties appoint surveyors:
- Agreed Surveyor — one impartial surveyor acting for both parties (cheaper, quicker). They do not represent either side; they administer the Act.
- Two surveyors — one appointed by each owner; together they select a Third Surveyor in advance to break any deadlock.
The surveyor(s) produce the Party Wall Award — a binding document that authorises the works and records the method and timing, working hours, access arrangements, the Schedule of Condition, and the allocation of costs (usually the building owner pays). Either party may appeal to the County Court within 14 days of the Award being served. Once the appeal window passes (or the appeal is resolved), the Award is final and work can proceed in line with it.

A Section 6 Notice of Adjacent Excavation follows the same format, stating that you intend to excavate within 3m (and deeper than the neighbour's foundations) or within 6m (within the 45° line), giving the depth and proximity, attaching sections showing the excavation relative to the neighbour's foundations, and proposing a start date not less than 1 month ahead.
Frequently Asked Questions
My neighbour hasn't replied — can I just start?
No. Silence is not consent. If the adjoining owner does not respond within 14 days, the Act deems a dispute to have arisen, and you must go through the surveyor/Award process before starting. Starting work on the strength of silence is a trespass and exposes you to an injunction.
What's the difference between 1 month and 2 months' notice?
It is set by the section. Line of Junction (Section 1) and Adjacent Excavation (Section 6) notices give 1 month. Party Structure (Section 2) notices — work to an existing party wall, including beams, underpinning, raising, or rebuild — give 2 months. You cannot start before the relevant period expires even if the neighbour consents immediately.
Is a party wall notice the same as planning permission or Building Control?
No — they are three separate things. Planning permission is about land use; Building Control checks Building Regulations; the Party Wall Act is a civil agreement with your neighbour. You can hold the first two and still be in breach of the Act. Always treat them as parallel, not interchangeable, processes.
What is a counter-notice?
A counter-notice (Section 4) lets the adjoining owner, within 1 month of receiving a Party Structure (Section 2) notice, ask the building owner to include extra works for the neighbour's benefit — for example building the wall higher or making provision for a flue. The building owner must do so where reasonable, and the adjoining owner pays for the additional works done solely for their benefit.
Who pays for the surveyors and the Award?
Usually the building owner — the party doing and benefiting from the works — pays the reasonable surveyor fees for preparing the Award, even where two surveyors are appointed. The Award itself can re-allocate costs in unusual cases. This is one reason to keep the works (and notices) clean: disputes drive surveyor fees up.
