My neighbour has ignored my Party Wall Notice – What do I do now?

You've done everything right. You served your Party Wall Notice in good time, kept it professional, and waited patiently. But the deadline has passed and your neighbour hasn't responded. So what happens now – and can your project still go ahead?

The short answer is yes. A non-response from your neighbour doesn't mean your project is blocked. But it does trigger a specific legal process you need to follow carefully.

What Counts as "Ignoring" a Party Wall Notice?

Under the Party Wall etc. Act 1996, your neighbour (the "Adjoining Owner") has 14 days from receiving the notice to respond in writing. They can:

- Consent – giving you the green light to proceed

- Dissent – triggering the appointment of a Party Wall Surveyor

- Do nothing – which is treated by the Act as a deemed dissent

So if they've simply not replied, the law considers them to have automatically dissented. This isn't a disaster – it's a defined situation the Act fully anticipates.

Step 1: Serve a Counter Notice (If Applicable)

Before moving to surveyors, check whether your neighbour needs to serve a counter notice. If your works involve excavation near their foundation or building on the boundary, they may have the right to make reasonable requests under the Act. This doesn't apply in every case, but it's worth confirming with a professional.

Step 2: Appoint a Party Wall Surveyor

Once the 14-day response window has passed without consent, both parties are required to appoint a Party Wall Surveyor. There are two routes:

Agreed Surveyor: Both you and your neighbour jointly appoint a single, impartial surveyor. This is often the most cost-effective and straightforward option.

Two Surveyors: Each party appoints their own surveyor. The two surveyors then work together (and, if necessary, appoint a third) to produce a legally binding Party Wall Award.

If your neighbour continues to be unresponsive and refuses to appoint their own surveyor, you can appoint one on their behalf. This is entirely lawful under Section 10(4) of the Act. You simply write to your neighbour informing them that you intend to appoint a surveyor for them if they don't respond within 10 days – and then do so if they don't.

Step 3: The Party Wall Award

Once surveyors are in place, they will produce a Party Wall Award (also called an Agreement). This legal document sets out:

- The scope and method of the proposed works

- The hours during which work can be carried out

- A Schedule of Condition recording the current state of your neighbour's property before works begin

- Any compensation provisions if damage occurs

The Award protects both parties. You are legally authorised to carry out the works described, and your neighbour has a documented record of their property's pre-existing condition.

How Long Does This Process Take?

From the point of deemed dissent, appointing surveyors and agreeing a Party Wall Award typically takes 4 to 8 weeks, depending on complexity and how cooperative your neighbour is. Factor this into your construction timeline from the outset.

Can I Just Start the Works Anyway?

No – and this is important. Proceeding without a valid consent or Award in place exposes you to significant legal risk. Your neighbour could apply for an injunction to halt your project, and you could be liable for any damage claims. The process exists to protect everyone, including you.

Key Takeaways for Homeowners

- A non-response to your Party Wall Notice is legally treated as dissent – not consent

- You can appo

int a surveyor on your neighbour's behalf if they remain unresponsive

- A Party Wall Award gives you legal authority to proceed and protects you from spurious claims

- Never start notifiable works without either written consent or an Award in place
