Key Points
- Party Wall Act 1996 is mandatory law in England & Wales
- Applies to shared walls between Slough terraced/semi-detached properties
- Requires 1-2 months' notice before starting work
- Typical party wall surveyor fees: £700-1,500 per property

What is the Party Wall Act 1996?
The Party Wall Act 1996 provides a legal framework for preventing and resolving disputes about party walls, boundary walls, and excavations near neighboring buildings. It's particularly relevant in Slough where terraced housing and semi-detached properties dominate the housing stock, especially in areas like Langley, Chalvey, and central Slough.
As a party wall specialist surveyor in Slough, I've seen the Act save countless homeowners from expensive disputes and legal battles. It provides a structured process that protects everyone's interests while allowing necessary building work to proceed.
When Does the Party Wall Act Apply?
Section 1: New Walls on Boundaries
Building a new wall astride the boundary line with your neighbor, or entirely on your own land but abutting the boundary.
Notice required: 1 month before work starts
Common in Slough: Side extensions on semi-detached properties
Section 2: Work on Existing Party Walls
Alterations to existing party walls including cutting into walls, inserting beams, removing chimney breasts, or underpinning.
Notice required: 2 months before work starts
Very common in Slough: Loft conversions and kitchen extensions in Victorian terraces
Section 6: Excavation Near Neighbors
Digging foundations within 3 meters (and below neighbor's foundations) or within 6 meters (and at 45° downward angle).
Notice required: 1 month before work starts
Common in Slough: Basement conversions and deep foundations

If you checked ANY boxes, you need to follow the Party Wall Act procedure.
The Party Wall Act Process: Step-by-Step
Step 1: Serve Party Wall Notice (1-2 Months Before)
You (the "Building Owner") must serve formal written notice on your neighbors (the "Adjoining Owners"):
- Section 1 & 6 works: 1 month notice minimum
- Section 2 works: 2 months notice minimum
- Notice must include: Details of proposed works, drawings, proposed start date
- How to serve: Delivered by hand, registered post, or left at property
Step 2: Neighbor Responds (14 Days)
Your neighbor has three options:
Option 1: Consent
Neighbor agrees in writing. Work can proceed. No surveyors needed.
Cost: £0 (ideal scenario)
Option 2: Dissent
Neighbor objects or doesn't respond within 14 days (deemed dissent).
Result: Party wall surveyors must be appointed
Option 3: No Response
If neighbor doesn't respond within 14 days, it's treated as dissent.
Result: Surveyors appointed automatically
Step 3: Appoint Party Wall Surveyors
If neighbor dissents or doesn't respond, surveyors must be appointed:
- Agreed Surveyor (recommended): One surveyor represents both parties (cheaper, faster)
- Two Surveyors: Each party appoints their own surveyor (more formal, higher cost)
- Third Surveyor: If disputes arise between the two surveyors, a third surveyor resolves them
Step 4: Schedule of Condition Survey
The surveyor(s) visit the adjoining property to document its current condition:
- Photographs of relevant areas
- Written descriptions of cracks, damage, decoration
- Creates baseline to assess any damage from works
- Typically takes 1-2 hours per property
Step 5: Party Wall Award Issued
The surveyor(s) prepare a Party Wall Award document setting out:
- Description of permitted works
- How and when work will be carried out
- Working hours (typically 8am-6pm Monday-Friday in residential areas)
- Who pays surveyor fees (usually the building owner)
- Process for resolving any damage claims
Step 6: Works Proceed
Once the Award is issued, work can commence. The surveyors may:
- Inspect works at key stages
- Ensure compliance with the Award
- Resolve any issues that arise
- Assess any damage claims after completion
Real Case Study: Loft Conversion in Langley
A homeowner in Langley wanted a loft conversion requiring a steel beam through the party wall with their Victorian terrace neighbor. They came to us after their builder said "you don't need party wall stuff."
What we did:
- Explained the legal requirement for Party Wall Act compliance
- Prepared and served proper Party Wall Notice
- Neighbor initially dissented (concerned about structural damage)
- We acted as Agreed Surveyor for both parties
- Conducted detailed Schedule of Condition
- Drafted comprehensive Party Wall Award
- Monitored works during installation
Outcome:
- Works completed smoothly with no disputes
- Neighbor's concerns addressed professionally
- No damage to adjoining property
- Total surveyor fees: £900 (split from £700 agreed surveyor fee + £200 monitoring)
- Saved potential legal costs of £5,000-10,000
The lesson? Proper Party Wall Act compliance prevented what could have been a nasty neighbor dispute and expensive legal battle.
Costs and Who Pays?
Party Wall Surveyor Fees
| Service | Typical Cost | Who Pays |
|---|---|---|
| Agreed Surveyor (basic) | £700-1,000 | Building Owner |
| Two Surveyors (one each) | £1,200-2,000 | Building Owner (both fees) |
| Schedule of Condition | £200-400 | Building Owner |

| Third Surveyor (disputes) | £500-1,500 | Building Owner |
| Complex projects | £2,000-5,000+ | Building Owner |
General Rule: Building Owner Pays
The Party Wall Act states that the building owner (person doing the work) pays all reasonable surveyor fees for both parties. This includes:
- Your own surveyor's fees
- Your neighbor's surveyor's fees (if they appoint one)
- Schedule of condition survey costs
- Party Wall Award preparation
- Any necessary monitoring visits
What Building Work Costs
Important: Party Wall Act compliance adds to your project costs. Budget for:
- Simple extensions: Add £700-1,500
- Loft conversions: Add £800-1,500
- Basement conversions: Add £1,500-3,000
- Complex projects: Add £2,000-5,000
Expert Insight from Emma Clarke
"Many Slough homeowners are shocked when they discover Party Wall Act compliance can add £1,000-2,000 to their project budget. However, this is money well spent. I've seen disputes where homeowners tried to avoid the Act—they ended up in court spending £10,000-20,000 in legal fees, plus had to stop work for months. The Party Wall Act isn't optional red tape; it's mandatory law designed to protect everyone. Factor it into your budget from day one, and you'll save yourself enormous stress and expense."
Common Mistakes to Avoid
1. "My Builder Says I Don't Need It"
Many builders mistakenly think the Party Wall Act doesn't apply or try to skip it to save time. It's not optional. If you don't comply, your neighbor can:
- Get an injunction stopping your work
- Sue you for damage (expensive without baseline Schedule of Condition)
- Force you to comply anyway (plus pay their legal costs)
2. Starting Work Before Notice Period Ends
You must wait the full notice period (1-2 months) even if your neighbor consents immediately. Starting early is a breach of the Act.
3. Using a Biased Surveyor
Don't use your builder or a surveyor with a conflict of interest. Party wall surveyors must act impartially, putting the Act's requirements first.
4. Not Serving Notice Properly
Informal mentions to neighbors aren't sufficient. Notices must be in writing, include all required information, and be properly served (hand-delivered, registered post, or left at the property).
5. Assuming Neighbors Will Be Reasonable
Even friendly neighbors may have legitimate concerns about structural work. The Party Wall Act provides a professional framework that protects everyone—don't try to wing it.
Resolving Party Wall Disputes
If disputes arise during or after works:
During Works
- Party wall surveyor investigates concerns
- Can require work to stop if Award breached
- May modify working methods or hours
- Ensures compliance with Award terms
After Works (Damage Claims)
- Neighbor claims damage from your works
- Surveyor compares to Schedule of Condition
- Determines if damage was caused by works
- Assesses repair costs
- Building owner must pay legitimate claims
Appealing an Award
If you disagree with a Party Wall Award, you can appeal to the County Court within 14 days. However:
- Appeals rarely succeed (surveyors follow established law)
- Court costs can be substantial
- Usually better to negotiate with surveyors

Request Your Free QuoteFrequently Asked Questions
Do I really need to follow the Party Wall Act?
Yes, it's mandatory law in England and Wales. If you don't comply, your neighbor can get an injunction stopping your work, sue you for damages, or force compliance (making you pay their legal costs). It's always cheaper and easier to comply from the start.
How much do party wall surveyors cost in Slough?
An Agreed Surveyor (serving both parties) typically costs £700-1,000 for straightforward projects. If both parties appoint their own surveyors, total costs are £1,200-2,000. Complex projects like basement conversions can cost £2,000-5,000. The building owner (person doing the work) pays all fees.
My neighbor and I are friendly—do we still need surveyors?
If your neighbor consents in writing within 14 days, you don't need surveyors. However, many neighbors consent then later claim damage without a Schedule of Condition to prove pre-existing state. We often recommend getting a Schedule of Condition even with friendly neighbors—it's insurance for both parties.
Can my neighbor stop my building work?
No. The Party Wall Act gives you the right to carry out necessary building work. Your neighbor can't stop you, but they can ensure proper procedures are followed and their property is protected. This is why the Act exists—to balance your rights with their protection.
How long does the Party Wall Act process take?
Minimum 1-2 months (notice period) plus 2-4 weeks for surveyor appointments, Schedule of Condition, and Award preparation. Total: 2-4 months from serving notice to starting work. Plan this into your project timeline from the beginning.
What if my neighbor doesn't respond to the notice?
If they don't respond within 14 days, it's treated as "deemed dissent" and party wall surveyors must be appointed. You can't just proceed because they didn't respond—you still must follow the full surveyor process.
Conclusion
The Party Wall Act 1996 is mandatory law that protects both building owners and neighbors during construction work affecting shared structures. In Slough, where terraced and semi-detached properties dominate, party wall matters are a daily reality for homeowners undertaking extensions, loft conversions, or significant renovations.
While the process adds time and cost to your project, it's a small price to pay compared to the potential expense of neighbor disputes, court proceedings, or injunctions stopping your work. Professional party wall surveyors ensure everyone's rights are protected while allowing necessary building work to proceed smoothly.
