Received a Party Wall Notice in Kensington? Here Is What to Do Next

It lands on your doormat without warning: a formal-looking document titled Party Wall Notice from your neighbour. If you live in a period conversion in Kensington, a Victorian townhouse in Notting Hill, or a garden flat in Holland Park, you have probably just learned that your neighbour intends to build — and the law requires them to tell you about it.

For most homeowners, that piece of paper triggers more anxiety than excitement. You might be worried about structural damage, loss of light, or the sheer disruption of what could be months of building work. The good news? The Party Wall etc. Act 1996 is on your side. It gives you clear rights, a structured timeline, and — crucially — the ability to protect your property without going to war with the people next door.

Here is exactly what to do when you receive a Party Wall Notice in Kensington.

What Is a Party Wall Notice and Why Did Your Neighbour Send It?

A Party Wall Notice is a legal document served under the Party Wall etc. Act 1996. Your neighbour is required to serve it at least two months before any work begins on:

• A shared (party) wall — cutting into it, thickening it, or raising it
• A new wall built up to or astride the boundary line
• Excavation within 3 or 6 metres of your building (depending on depth)

In Kensington, the most common triggers are basement excavations (especially under Victorian and Edwardian terraces), rear extensions across the back of period houses, and loft conversions that raise the party wall. If your neighbour has planning permission for any of these, the Party Wall Notice is the legal step that follows — it is not optional for them, and it is not a request for your permission to build. It is a notice informing you of their right to build, subject to safeguards that protect you.

You Have 14 Days — Do Not Ignore It

The clock starts ticking the day the notice is served. You have 14 days to respond in writing. If you do nothing, the Act deems you to have dissented (disagreed), and your neighbour can appoint a surveyor on your behalf — someone you did not choose. That is rarely the best outcome.

Step one: Note the date of service on the notice. Mark day 14 on your calendar. Then take a breath — you have time to make an informed decision.

Your Two Options: Consent or Dissent

You have two formal responses available under the Act. Each has very different consequences.

Option 1: Give Your Consent in Writing

If you sign and return the notice giving your consent, your neighbour can proceed with the work described. You waive your right to have a surveyor scrutinise the schedule of work or the award. If something goes wrong — structural damage, cracks, loss of support — you still have your common-law rights, but you have lost the statutory framework that makes dispute resolution simpler and faster.

When consent makes sense: Only when you know and trust the neighbour, the work is minor (e.g. inserting a few wall ties), and you are confident the builder is reputable. For any substantial project — basement dig, side return, loft extension — consent is rarely advisable.

Option 2: Dissent — and Appoint Your Own Surveyor

Dissent does NOT mean you are trying to block the work. It means you are exercising your legal right to have the work independently overseen. You can dissent simply by responding to the notice saying you disagree — or by doing nothing and letting the 14 days expire (which counts as dissent by default).

Once you dissent, you and your neighbour each appoint a surveyor (or jointly agree on a single Agreed Surveyor). The two surveyors then draw up a Party Wall Award — a legally binding document that sets out:

• Exactly how and when the work will be carried out
• A schedule of condition (a detailed photographic and written record of your property before work starts)
• Working hours, access rights, and protection measures
• Who bears the cost of the surveyors (usually the building owner)

The Party Wall Award is your single most important protection. If cracks appear later, you have photographic evidence from the schedule of condition. If the builders are negligent, the Award gives you clear recourse. And because the surveyor is impartial (their duty is to the Act, not to either party), the process is designed to be fair to both sides.

Why Appointing Your Own Surveyor (Adjoining Owner Appointment) Is Often the Smartest Move

Many homeowners in Kensington worry that appointing a surveyor means they are being difficult or starting a confrontation. The opposite is true. Appointing a RICS-qualified Party Wall surveyor is the single most effective way to de-escalate the process and ensure everything is done properly.

Think of the surveyor as your technical advocate. They will:

• Review the neighbour’s drawings and method statement for technical gaps
• Prepare a thorough schedule of condition of your property (essential for Kensington’s older housing stock, where pre-existing cracks and settlement are common)
• Negotiate the terms of the Award so your property is protected
• Make site visits during the work to check compliance
• Resolve disputes quickly without you having to argue with your neighbour directly

In nearly every case involving basement excavations in South Kensington or substantial rear extensions in Holland Park, the cost of appointing your own surveyor is a fraction of the potential repair bill if something goes wrong. And because the Act usually makes the building owner (your neighbour) pay the surveyor’s reasonable fees, it rarely costs you anything upfront.

Kensington-Specific Considerations

Kensington presents a number of factors that make professional Party Wall advice particularly important:

Basement Excavations

Kensington’s basement boom has made Party Wall notices a near-daily occurrence. Deep excavations within 3 metres of a neighbouring structure require a Party Wall Award. London clay can shift unpredictably, and a robust schedule of condition is essential before a single shovelful of earth is moved.

Period Conversions

Many of Kensington’s large Victorian and Georgian houses have been subdivided into flats. If you own a leasehold flat in a converted house, the Party Wall Act still applies to you. Your freeholder or superior landlord may also need to be notified, and the party structure between flats requires careful handling.

Conservation Areas

Large parts of Kensington, including the Kensington Conservation Area, the Holland Park Conservation Area, and parts of Notting Hill, are subject to extra planning controls. While the Party Wall Act is separate from planning permission, your surveyor needs to understand how conservation area constraints interact with the building works — and your Award should reflect any additional conditions.

Close Party Walls

In terraced houses across South Kensington and Notting Hill, the party walls are often shared by several properties in a row. Work on one wall can affect the structural integrity of a whole terrace. A Party Wall Award ensures the building owner’s surveyor, the adjoining owner’s surveyor, and any third-surveyor arrangements account for the wider row.

Your Next Steps

If you have received a Party Wall Notice and you are unsure what to do next, do not panic — and do not ignore it. Here is your action plan:

1. Check the date the notice was served and mark day 14.
2. Do not sign the notice without professional advice unless the works are genuinely trivial.
3. Call Ekron for a no-obligation discussion about your situation.
4. Let us handle the notice response and, if needed, your surveyor appointment.

We have helped dozens of Kensington homeowners navigate the Party Wall process — from the moment the notice arrives through to the completion of works and the final schedule of condition check. We make the process clear, professional, and as stress-free as possible.
