Quick Answer: What to Do When You Receive a Party Wall Notice
You have THREE options within 14 days:
- Consent in writing – Agree to the work (no surveyor needed, but you’re not waiving damage rights)
- Dissent or stay silent – Triggers surveyor appointment (you choose your own or agree to share one)
- Serve a counter notice – Request additional work at the same time (within 1 month)
Important: Not responding = automatic dissent = surveyors get appointed. This protects you but costs your neighbour more. You don’t pay surveyor fees – your neighbour pays for both surveyors under the Party Wall Act.
Understanding the Notice You Received
You’ve just found an official-looking letter in your mailbox. It mentions the “Party Wall etc. Act 1996” and describes building work your neighbour plans to do. Don’t panic – this is a normal legal requirement, not a sign of conflict.
What is a Party Wall Notice?
A formal notification required by law when your neighbour plans building work that:
- Affects a shared wall between your properties
- Involves building on or near the boundary
- Requires excavation near your foundations
This notice gives you:
- Advance warning of the work
- Time to understand what’s proposed
- Opportunity to protect your property
- Legal rights under the Act
Three Types of Notices You Might Receive
1. Party Structure Notice (Section 2)
You’ll receive this if your neighbour is:
- Cutting into the party wall (inserting steel beams for loft conversion)
- Raising the party wall height
- Underpinning the party wall
- Removing chimney breasts from the party wall
- Any structural work to the shared wall
Notice period: Must be served at least 2 months before work starts
Most common in London: Loft conversions and rear extensions
2. Line of Junction Notice (Section 1)
You’ll receive this if your neighbour is:
- Building a new wall on the boundary line
- Building a new wall straddling the boundary (requires your consent)
- Constructing a boundary garden wall
Notice period: At least 1 month before work starts
Common scenarios: Side return extensions, new boundary walls
3. Notice of Adjacent Excavation (Section 6)
You’ll receive this if your neighbour is:
- Excavating within 3 metres of your building AND going deeper than your foundations
- Excavating within 6 metres AND going deeper than a 45-degree line from your foundation base
Notice period: At least 1 month before work starts
Most common: Basement conversions in London
What Should the Notice Include?
A valid notice must contain:
- Your neighbour’s name and address (the “Building Owner”)
- Your name and address (the “Adjoining Owner”)
- Description of the proposed work
- When they intend to start
- Plans/drawings showing the work
- Whether special foundations are involved
- Date the notice was served
Red flag: If the notice is missing key information, it may be invalid. You can question validity, but it’s often easier to just proceed with the process.
“Building Owner” vs “Adjoining Owner”
Building Owner: Your neighbour doing the work
Adjoining Owner: You (the person receiving the notice)
These are legal terms from the Act – don’t overthink them!
Your Three Options Explained
You must respond within 14 days of receiving the notice. Here are your choices:
Option 1: Give Written Consent ✅
What this means: You write back saying you agree to the work as described.
What happens:
- ✅ No surveyors needed (saves your neighbour £700-£1,500)
- ✅ No Party Wall Award required
- ✅ Faster process for your neighbour
- ✅ Work can proceed after notice period expires (1-2 months)
Important: Consenting does NOT mean:
- ❌ You waive your right to claim for damage
- ❌ You’re giving permission (the Act gives them the right)
- ❌ You can’t complain if problems occur
You’re still protected: If their work damages your property, you can still claim – consent just means you trust them to proceed without formal oversight.
Example consent letter:
[Your Name]
[Your Address]
[Date]
Dear [Neighbour's Name],
Re: Party Wall Notice dated [date] for work at [neighbour's address]
I acknowledge receipt of your Party Wall Notice and consent to the
proposed works as described.
This consent does not waive my rights under the Party Wall etc. Act
1996 to seek remedies for any damage caused by the works.
Yours sincerely,
[Your signature]
[Your name]
When to choose this option:
- ✅ The work is minor and straightforward
- ✅ You trust your neighbour and their contractor
- ✅ Plans look reasonable and professional
- ✅ Previous good relationship with neighbour
- ✅ You understand the risks
London reality: Only 10-15% of adjoining owners give written consent for significant projects. Most prefer the protection of formal process.
Option 2: Dissent or Stay Silent 🛡️
What this means: You either:
- Write back saying you dissent (disagree), OR
- Don’t respond at all within 14 days
Both have the same effect – you’re now in “dispute” under the Act.
“Dispute” doesn’t mean conflict: It’s just a technical legal term that triggers the surveyor appointment process. You can dissent even if you’re fine with the work – you just want formal protections.
What happens next:
- ✅ Surveyors must be appointed
- ✅ Schedule of Condition documents your property’s current state
- ✅ Party Wall Award sets formal terms for the work
- ✅ Your property gets professional protection
- ✅ Clear process for handling any damage
You have TWO surveyor options:
Option 2A: Agreed Surveyor (Shared Surveyor)
Both you and your neighbour jointly appoint one surveyor who acts impartially for both parties.
Advantages:
- ✅ Faster process (4-6 weeks typically)
- ✅ Cheaper for your neighbour (£700-£1,200 vs £1,400-£2,500)
- ✅ Less formal/adversarial
- ✅ Works well for straightforward projects
Disadvantages:
- ❌ No dedicated “your side” advocate
- ❌ Must trust one person to be fair to both
- ❌ If you become unhappy, harder to contest
When to choose: Standard loft conversions, simple extensions, good neighbour relations, straightforward work
Option 2B: Two Surveyors (Separate Representation)
You appoint your own surveyor, your neighbour appoints theirs. The two surveyors work together and select a “Third Surveyor” (only involved if the two disagree).
Advantages:
- ✅ Dedicated representation for your interests
- ✅ Your surveyor advocates for you specifically
- ✅ More thorough review of plans
- ✅ Better for complex/contentious situations
- ✅ Professional oversight throughout
Disadvantages:
- ❌ Takes longer (6-8 weeks typically)
- ❌ More expensive for your neighbour (£1,400-£2,500 total)
- ❌ More formal process
When to choose: Basements, major structural work, high-value properties, complex projects, any concerns about the work
Important: Your neighbour pays ALL surveyor fees (yours AND theirs). You don’t pay anything.
Example dissent letter:
[Your Name]
[Your Address]
[Date]
Dear [Neighbour's Name],
Re: Party Wall Notice dated [date] for work at [neighbour's address]
I acknowledge receipt of your Party Wall Notice dated [date].
I do not consent to the proposed works as described and am therefore
dissenting under the Party Wall etc. Act 1996.
[CHOOSE ONE:]
Option A: "I propose that we appoint [Surveyor Name] of [Company] as
our Agreed Surveyor to act impartially for both parties."
Option B: "As we are now in dispute, I am appointing [Surveyor Name]
of [Company] as my surveyor. Please confirm your surveyor's details."
Option C: "I will appoint a surveyor within the next 10 days and
provide you with their details."
Yours sincerely,
[Your signature]
[Your name]
Option 3: Serve a Counter Notice 📝
What this means: You agree to the work, BUT you request additional work be done at the same time (within 1 month of receiving their notice).
Example scenarios:
- While you’re working on the party wall, please repair the cracks on my side too
- If you’re raising the party wall, make it high enough for my future loft plans
- “While you’re underpinning, extend it to underpin the full length”
What happens:
- Your neighbour has 14 days to agree or disagree
- If they disagree, surveyors determine what’s reasonable
- If the additional work benefits only you, you may have to pay for it
When to use: Rare (5% of cases), but sensible if you’re planning similar work soon and coordination makes sense
Reality: Most adjoining owners don’t serve counter notices – the timing and costs usually don’t align.
Should You Consent or Dissent? Decision Framework
This is the most important decision. Here’s how to think through it:
Choose CONSENT if ALL of these apply:
✅ The work is straightforward and minor
✅ Your neighbour is professional and trustworthy
✅ Plans are detailed and look professionally prepared
✅ Good existing relationship
✅ You understand construction/property matters
✅ Your property is modern and robust
✅ Low risk of damage (e.g., Velux windows, not basement)
Risk level: Low to Medium
Your protection: Legal right to claim damage, but no formal documentation baseline
Choose DISSENT (Surveyor Process) if ANY of these apply:
⚠️ The work is major or complex (basement, major extension, loft conversion)
⚠️ Your property is Victorian/Edwardian or fragile
⚠️ You have concerns about the quality of their contractor
⚠️ Plans are vague or unprofessional
⚠️ Your property is high value (difficult to prove damage without baseline)
⚠️ Previous issues with this neighbour
⚠️ You’re uncertain about construction matters
⚠️ You want formal protection and documentation
Risk level: Managed through professional process
Your protection: Comprehensive Schedule of Condition, formal Award, surveyor oversight
The Practical London Perspective
For loft conversions (most common): 85% of adjoining owners choose dissent/surveyor process
Why? Because:
- Victorian/Edwardian properties are sensitive to vibration
- Steel beam cutting creates risk
- Schedule of Condition provides crucial baseline
- Neighbour pays for your surveyor (no cost to you)
- Professional oversight ensures proper working methods
Our recommendation: Unless the work is genuinely minor, choose the surveyor process. The protection is worth it, and you don’t pay for it.
The Questions to Ask Yourself
1. “What’s the worst that could happen?”
- Structural cracks requiring £5,000+ repairs?
- Decorative damage costing £2,000?
- Minor hairline cracks (£300-500)?
If worst case is expensive, get surveyor protection.
2. “How would I prove what was pre-existing?”
- Do you have comprehensive photos of every room right now?
- Can you document all current cracks, defects, conditions?
If not, Schedule of Condition by professional surveyor is valuable.
3. “Do I trust this will be done carefully?”
- Are they hiring experienced contractors?
- Do they seem professional and organized?
- Have they communicated well so far?
If any doubts, surveyor oversight ensures standards.
4. “Is this worth the relationship strain?”
- Will insisting on surveyors damage relations?
Reality: Most neighbours expect surveyors for major work. It’s normal and professional. Explain it’s standard protection, not personal mistrust.
How to Appoint a Party Wall Surveyor
If you’ve decided to dissent and want surveyor protection, here’s how to appoint one:
Finding a Party Wall Surveyor
Look for:
- ✅ Pyramus and Thisbe Club Chartered Surveyor (essential)
- ✅ Specific party wall experience (50+ awards)
- ✅ Member of Pyramus & Thisbe Club (specialist organization)
- ✅ Local to your London area (knows property types)
- ✅ Professional indemnity insurance (£1-2 million minimum)
Where to find surveyors:
- Pyramus and Thisbe Club website directory
- Pyramus & Thisbe Club member list
- Google: “party wall surveyor [your borough]”
- Recommendations from friends/family who’ve done similar work
What to Ask Potential Surveyors
Before appointing, ask:
- “How many party wall awards have you completed?”
Good answer: 50+, ideally 100+ - “Do you have experience with [type of work] in [property type]?”
Want: Specific experience with your scenario (e.g., Victorian loft conversions) - “Will you be doing the work or delegating to junior staff?”
Best: The person you speak to will handle your case - “What’s your approach as an adjoining owner’s surveyor?”
Look for: Thorough, protective but reasonable, good communication - “How long typically from appointment to Award?”
Standard answer: 4-6 weeks (agreed surveyor) or 6-8 weeks (two surveyors) - “What’s your fee structure?”
Remember: Your neighbour pays, but you should understand what’s being charged - “Can I contact you during the work if issues arise?”
Best answer: Yes, with clear contact info and responsiveness commitment
The Appointment Process
Step 1: Contact 2-3 surveyors for initial discussion (most offer free 15-min consultation)
Step 2: Choose the surveyor you’re most comfortable with
Step 3: Confirm appointment in writing to your neighbour:
[Your Name]
[Your Address]
[Date]
Dear [Neighbour's Name],
Re: Party Wall Matter at [neighbour's address]
Further to your Party Wall Notice dated [date], I am appointing
[Surveyor Name] of [Company Name] as my surveyor under the Party
Wall etc. Act 1996.
Contact details:
[Surveyor Name]
[Company Address]
[Phone]
[Email]
Please arrange for your surveyor to contact mine directly.
Yours sincerely,
[Your signature]
Step 4: Your surveyor takes over from here
If You Don’t Appoint a Surveyor
What happens: If you don’t appoint someone within 10 days of dissenting, your neighbour can appoint a surveyor “on your behalf.”
This surveyor still protects you: Even though appointed by your neighbour, they must act in your interests under the Act.
Why you might not appoint: Inaction, uncertainty, or just trusting your neighbour to appoint someone fair.
Risk: You don’t choose who represents your interests.
Better approach: Even if you want to be hands-off, take 30 minutes to appoint someone you’ve spoken with. It’s free to you, and you control the choice.
What Happens Next: The Process
Once surveyors are appointed, here’s the typical timeline:
Stage 1: Surveyor Communication (Week 1-2)
Your surveyor will:
- Contact your neighbour’s surveyor (if two-surveyor approach)
- Request full plans and structural calculations
- Review the proposed work
- Identify any concerns or needed clarifications
You’ll be asked:
- Contact information and availability
- Access arrangements for Schedule of Condition
- Any specific concerns about the work
Stage 2: Schedule of Condition (Week 2-4)
Most important step for you:
Your surveyor visits your property to document everything:
- Every room (usually 50-150 photographs)
- All walls, ceilings, floors
- Every crack, mark, defect
- Structural condition assessment
- External areas if relevant
- Gardens, boundary walls, etc.
Why this matters: This becomes the “before” record. After your neighbour’s work, this document proves what was pre-existing vs. new damage.
Your role:
- Provide access (2-3 hour visit typically)
- Point out any concerns
- Ask questions about the process
Timeline: Usually takes 2-3 weeks to arrange (coordinating schedules)
Stage 3: Award Preparation (Week 4-7)
Surveyor(s) draft the Party Wall Award – a legally binding document that specifies:
Contents:
- What work is permitted (exactly as notified or with modifications)
- How the work must be done (working hours, methods, protections)
- When work can start (after notice period expires)
- Access rights (when and how surveyors/workers can access your property)
- Protective measures (scaffolding requirements, dust control, etc.)
- Damage resolution (how claims will be handled)
- Schedule of Condition (attached as baseline)
- Costs (confirms your neighbour pays surveyor fees)
Your involvement:
- Your surveyor may ask about acceptable working hours
- Review draft Award (your surveyor explains it)
- Raise any concerns before finalization
Stage 4: Award Service (Week 7-8)
Award is served on both parties:
- Legally binding document
- Sets terms for the entire project
- 14-day appeal period (rarely used)
After 14 days: Award becomes final (unless appealed to County Court)
Stage 5: Work Proceeds (Months 2-6 typically)
During your neighbour’s building work:
- Must comply with Award conditions
- You can contact your surveyor if concerns arise
- Surveyor may visit to check compliance
- Keep notes/photos if you notice any issues
Your rights during work:
- Access for inspection (reasonable notice)
- Complain if Award conditions violated
- Request surveyor intervention if problems
Stage 6: Post-Completion Inspection (After work finishes)
Final critical step:
Surveyor inspects your property again, comparing against Schedule of Condition.
Three possible outcomes:
A) No damage found (70-75% of careful projects):
- Surveyor confirms no work-related issues
- Process concludes
- Happy ending!
B) Minor damage found (20-25%):
- Small cracks, plaster issues, cosmetic damage
- Your neighbour must make good (per Award)
- Typically costs £300-£1,500
- Surveyor oversees repairs
C) Significant damage (5%):
- Structural issues, major defects
- Full remediation required
- Structural engineer may be needed
- Costs £2,000-£10,000+
- Your neighbour is liable
Your Rights as an Adjoining Owner
Understanding your rights helps you feel confident throughout the process.
Legal Rights Under the Party Wall Act
You have the right to:
✅ 14 days to respond to notices (2 calendar weeks from receipt)
✅ Appoint your own surveyor at your neighbour’s expense
✅ Comprehensive Schedule of Condition documenting your property
✅ Formal Party Wall Award setting clear terms
✅ Refuse special foundations on your land (requires your written consent)
✅ Reasonable protective measures to safeguard your property
✅ Access during work to inspect (with reasonable notice)
✅ Not suffer unnecessary inconvenience beyond what’s inevitable
✅ Compensation for damage caused by the work
✅ Security for expenses (rare, for very high-risk projects like basements)
✅ Appeal the Award to County Court within 14 days
Practical Rights (What This Means)
Working hours:
- Typically 8am-6pm Monday-Friday, 8am-1pm Saturday
- Award will specify
- Can request more restrictive hours if reasonable
Methods and protections:
- Can request dust control measures
- Scaffolding must be safe and secure
- Temporary propping where needed
- Professional contractors expected
Access to your property:
- Surveyors need access for Schedule and inspections
- You must allow reasonable access
- They must give reasonable notice (usually 7-14 days)
- You can request specific times
Information:
- Right to see full plans and structural calculations
- Right to ask questions about the work
- Your surveyor explains everything
What You Cannot Do (Common Misconceptions)
You CANNOT:
❌ Stop the work entirely (if they follow proper process)
❌ Demand payment for “allowing” the work
❌ Impose unreasonable conditions that prevent legitimate work
❌ Refuse access for Schedule of Condition (court can order access)
❌ Block surveyors from doing their job
❌ Delay indefinitely by not responding (auto-dissent after 14 days)
❌ Negotiate a “fee” from your neighbour to consent
The Act is designed to facilitate building work, not to give adjoining owners veto power. Your rights are to influence how work is done and to be protected from damage, not to stop it.
Costs: Who Pays What?
Good News: You Don’t Pay Surveyor Fees
Your neighbour (Building Owner) pays:
- ✅ Their own surveyor
- ✅ YOUR surveyor (yes, really!)
- ✅ The agreed surveyor (if using one)
- ✅ Third Surveyor (if needed)
- ✅ All reasonable costs of the process
You pay: Nothing for the surveyor process
Why this structure: Parliament decided the person benefiting from and initiating the work should bear the costs. This ensures adjoining owners aren’t financially penalized for protecting their interests.
Typical Costs (Your Neighbour Pays)
| Surveyor Arrangement | Total Cost (All Paid by Your Neighbour) |
|---|---|
| Agreed Surveyor | £700-£1,200 |
| Two Surveyors (one for each party) | £1,400-£2,500 |
| Complex projects (basements) | £2,500-£5,000+ |
What If Your Surveyor’s Fees Are “Excessive”?
Protection: Surveyor fees must be “reasonable.” If your neighbour believes your surveyor is overcharging:
- Their surveyor can challenge
- Third Surveyor can review
- County Court can ultimately decide
Reality: Most party wall surveyors charge similar market rates. True overcharging is rare and won’t stand scrutiny.
Best practice: Appoint a reputable party wall surveyor with fair, transparent pricing.
Costs You Might Incur
If damage occurs:
- Your neighbour pays for repairs (per Award)
- You don’t pay anything
Only scenarios where you might pay:
- If you serve counter notice requesting additional work for your sole benefit
- If you appeal Award to court and lose (very rare)
- If you refuse reasonable access and court orders you to allow it
Timeline: What to Expect
Realistic timeline from receiving notice to work starting:
| Stage | Your Action Required | Duration | Cumulative Time |
|---|---|---|---|
| Receive notice | Read and understand | Day 0 | – |
| Response period | Decide: consent or dissent | 14 days | 2 weeks |
| Surveyor appointment | Appoint or agree to surveyor | 1-2 weeks | 3-4 weeks |
| Schedule of Condition | Provide access (2-3 hours) | 2-3 weeks | 5-7 weeks |
| Award preparation | Minimal—review when ready | 3-5 weeks | 8-12 weeks |
| Award served | Read and understand | Day X | ~10-12 weeks |
| Appeal period | None (unless appealing) | 14 days | ~12-14 weeks |
| Notice period expires | None | (Concurrent, 2 months from notice) | – |
| Work starts | None | – | 10-14 weeks total |
Minimum from notice to work starting: 2-3 months
Typical: 3-4 months
With complications: 4-6 months
Red Flags to Watch For
Concerning Notice Content
🚩 Notice missing key information (no plans, vague description)
🚩 Notice served by builder, not property owner (may be invalid)
🚩 Unrealistic start date (less than notice period)
🚩 Mentions “special foundations” but no detail (you must consent separately)
🚩 No mention of structural engineer for major work
Concerning Neighbour Behavior
🚩 Pressure to consent immediately (“Sign this today or I’ll be delayed”)
🚩 Offers payment to consent (“I’ll give you £500 to agree”)
🚩 Threatens or intimidates (“You’ll regret making this difficult”)
🚩 Work already started before notice served or process complete
🚩 Dismissive of your concerns (“It’s nothing, don’t worry about it”)
What to Do If You See Red Flags
Step 1: Don’t be pressured—you have 14 days to respond thoughtfully
Step 2: Consult a party wall surveyor immediately (free initial call usually)
Step 3: If notice is invalid, surveyor can advise on challenging it
Step 4: If work has started without proper notice, surveyors or legal injunction may be needed
Step 5: Document everything—emails, letters, dates, conversations

Frequently Asked Questions
What happens if I don’t respond to the party wall notice?
Automatic dissent: After 14 days of silence, you’re deemed to be in dispute. Your neighbour must then either appoint an agreed surveyor or appoint a surveyor on your behalf (after 10 more days). The process continues even if you do nothing.
Can my neighbour start work before the process is complete?
No. They must wait until:
- The notice period expires (1-2 months from service), AND
- A Party Wall Award is in place (if you dissented or stayed silent)
Starting early is a breach of the Act and you can seek an injunction.
Do I have to let surveyors into my house?
Yes, for Schedule of Condition. The Act gives surveyors right of access with reasonable notice (usually 7-14 days). If you refuse, they can apply to a magistrate for an order allowing entry.
What if the work damages my property?
You’re protected: The Party Wall Award requires your neighbour to make good any damage caused. The Schedule of Condition proves what was pre-existing. Your surveyor oversees the resolution.
Can I charge my neighbour a fee to agree to the work?
No. This isn’t permitted under the Act. Your neighbour has legal rights to do the work if proper process followed. You can’t extort payment for consent.
How long does the surveyor process usually take?
Typical timeline:
- Agreed surveyor: 4-6 weeks from appointment to Award
- Two surveyors: 6-8 weeks
- Complex projects: 8-12 weeks
