1. The best case: consent

If your neighbour receives your notice and consents in writing, the statutory process is complete almost immediately.

Timeline with consent:

  • Serve notice
  • Neighbour consents (in writing)
  • Works can proceed

This can happen within days if your neighbour responds promptly. There’s no minimum waiting period once valid consent is given.

For straightforward works with cooperative neighbours, this is common. Many Party Wall matters are resolved by consent within a week or two of serving notice.

2. The notice period

If your neighbour doesn’t consent immediately, there’s a statutory notice period:

For works to party structures: 2 months minimum notice (but only 14 days to respond)

For line of junction works (building a new wall): 1 month minimum notice

For excavation works: 1 month minimum notice

The notice period is how much advance warning you must give before starting work. The response period is how long your neighbour has to consent or dissent.

Important distinction:

  • Works to existing party walls: You must give 2 months’ notice before starting, but neighbour has 14 days to respond
  • Excavation: 1 month notice before starting, 1 month to respond

If your neighbour dissents (or doesn’t respond, which is deemed dissent), you need a Party Wall Award before works can begin.

3. The Award process

When surveyors must prepare an Award, the timeline extends:

Surveyor appointment: 1-2 weeks typically

  • You appoint your surveyor
  • Neighbour appoints theirs (or agrees to an Agreed Surveyor)
  • If they don’t respond, the 10-day letter process adds time

Condition survey: 1-2 weeks

  • Surveyor(s) inspect the adjoining property
  • Schedule and photograph existing condition
  • Coordinate access with neighbour

Award preparation: 2-4 weeks

  • Draft Award and drawings
  • Negotiation between surveyors if there are two
  • Agreement on terms and conditions

Service and appeal period: 14 days

  • Award served on both parties
  • 14-day appeal period before Award becomes final

Realistic total for Award process: 6-10 weeks

This assumes reasonable cooperation. Complications extend it.

4. Factors that speed things up

Agreed Surveyor

When both parties agree to appoint a single surveyor, the process is faster. No negotiation between surveyors, simpler administration, one fee instead of two.

Early engagement

Talking to your neighbour before serving formal notice helps. Explain what you’re doing, why Party Wall notices are required, and what the process involves. Informed neighbours respond faster.

Straightforward works

Simple works (like a loft conversion with beam bearing on a party wall) generate simpler Awards than complex basement excavations next to shallow foundations.

Accessible properties

If the surveyor can access the adjoining property easily for condition survey, there’s no delay waiting for appointments.

Responsive parties

Everyone responding promptly to correspondence keeps things moving.

5. Factors that slow things down

Non-engagement

Neighbours who don’t respond trigger the 10-day letter process. Each missed deadline adds time.

Disputes about scope

If there’s disagreement about whether works are notifiable, or exactly what’s covered, expect delay while this is resolved.

Complex works

Basement excavations, underpinning, works affecting stability — these require more detailed Awards and often more negotiation.

Difficult access

If condition surveys can’t be arranged promptly (neighbour away, access issues, difficult schedules), the whole process waits.

Multiple adjoining owners

Terraced properties may have neighbours on both sides. Each relationship runs separately. You’re waiting for the slowest.

Third surveyor involvement

If the two appointed surveyors can’t agree, a Third Surveyor may need to determine the Award. This is rare but adds weeks or months.

Hostile relationships

Neighbours actively obstructing or disputing everything extend timelines significantly. Fortunately this is unusual.

6. Working backwards from your start date

If you have a target date for starting works:

Consent route (optimistic): Allow 2-4 weeks

  • Serve notice as soon as possible
  • Follow up to encourage prompt consent
  • Have a surveyor on standby if consent doesn’t come

Award route (realistic): Allow 10-14 weeks

  • Serve notice
  • If no consent within 14 days, immediately instruct surveyor
  • Award process runs parallel to your other preparations
  • Build in contingency for delays

Complex or contentious: Allow 4-6 months

  • Basement works, difficult neighbours, multiple parties
  • Start the process early
  • Consider it a critical path item for your project programme

7. Can you speed up the process?

Within limits:

Serve early — Don’t wait until you need to start. Serve as soon as you know works are happening.

Be proactive — Follow up with your neighbour. Offer to explain the process. Make it easy for them to consent.

Appoint quickly — If consent isn’t coming, appoint your surveyor immediately. Don’t wait hoping things change.

Choose experienced surveyors — Surveyors who do this regularly work efficiently. Inexperienced surveyors take longer.

Be responsive — When your surveyor needs information or decisions, respond quickly. Don’t be the delay.

Agree an Agreed Surveyor — If your neighbour is amenable, one surveyor is faster than two.

8. What you can’t shortcut

Notice periods — Statutory minimums exist for good reason. You can’t give less notice than required.

Response periods — Your neighbour gets 14 days (or a month for excavation). You must wait.

Appeal period — The 14-day appeal window after Award service can’t be waived.

Proper process — Cutting corners creates legal risk. If you proceed without proper Award, your neighbour could seek an injunction stopping the works.

9. Planning your project

Party Wall matters should be on your critical path:

Identify notifiable works early — During design, identify what needs Party Wall notice.

Serve when you submit for Building Regulations — The timescales are similar. Running in parallel makes sense.

Don’t assume consent — Plan for the Award route even if you hope for consent.

Brief your contractor — Make sure they understand Party Wall may affect start dates.

Update as things progress — Keep project team informed of Party Wall status.

Key Takeaways

  • Consent can be quick — Days or weeks if neighbours respond positively
  • Award process typically takes 6-10 weeks — Sometimes longer with complications
  • Statutory notice periods are minimum — 2 months for party wall works, 1 month for excavation
  • Start early — Party Wall should be on your critical path
  • Agreed Surveyors are faster — One surveyor is more efficient than two
  • Build in contingency — Delays happen; don’t program works too tightly
