Party Wall Award When Selling Your Property

If you have built an extension, converted a loft involving the shared wall, or carried out any excavation near a neighbouring property, the Party Wall etc. Act 1996 almost certainly applied. When you come to sell, the buyer's solicitor will want to see the party wall award — or evidence that the adjoining owner consented in writing. This guide explains what an award is, what it contains, and how to handle the situation whether you have the documentation or not.

Party wall documentation is one of the most common gaps that surfaces during conveyancing enquiries. Understanding what the buyer's solicitor needs — and why — will help you prepare in advance and avoid the delays that arise when this issue is raised for the first time mid-sale. For a full picture of what documents typically come up, see our guide on what is in a property certificate pack.

What is a party wall award?

A party wall award is a formal, legally binding document produced under Section 10 of the Party Wall etc. Act 1996. It is prepared by an agreed surveyor (one appointed jointly by both parties) or by two surveyors (one for each party) when a dispute arises over proposed notifiable building work.

A dispute under the Act does not require any actual disagreement between neighbours. It is automatically deemed to have arisen whenever the adjoining owner either dissents to the party wall notice or simply fails to respond within 14 days of receiving it. Many adjoining owners do not respond within the deadline, which means a party wall award is produced even where there is no genuine objection.

The award is a statutory document — it derives its authority from the Act itself, not from a private contract between the parties. Once served, it is enforceable in the county court and is binding on successors in title, which means your buyer inherits both the rights and the obligations set out in it when they purchase your property.

What does a party wall award contain?

A typical party wall award includes the following elements:

• The names and addresses of the building owner and the adjoining owner
• The names and appointment details of the surveyor or surveyors
• A description of the notifiable work, often with reference to plans
• Conditions governing how the work is to be carried out: working hours, protective measures, access arrangements, and obligations to make good any damage
• Provisions for access to the adjoining property to inspect or carry out work
• A schedule of condition — a detailed photographic and written record of the adjoining property immediately before work begins
• The date of the award and the signatures of the appointed surveyor or surveyors

The schedule of condition is particularly important. It establishes the baseline condition of the adjoining property so that any damage attributable to the building work can be identified and distinguished from pre-existing defects. Buyers' solicitors will normally ask for the schedule of condition as part of the award documentation — providing one without the other is incomplete.

The difference between an award and a consent

The terms “party wall award” and “party wall agreement” are sometimes used interchangeably, but they are technically different documents:

For conveyancing purposes, both are acceptable evidence that the Party Wall etc. Act 1996 was complied with. The buyer's solicitor will accept either a written consent letter from the adjoining owner or a formal party wall award. What they will not accept is neither — that is, work having been carried out with no documentation at all.

Which work triggers the Party Wall Act?

The Party Wall etc. Act 1996 applies to three categories of work, each covered by a different section:

Section 1 — building on or near the boundary line

Section 1 applies where you propose to build a new wall or structure on the boundary between your property and your neighbour's, or astride it with footings projecting onto their land. You must serve a Section 1 notice at least one month before work begins.

Section 2 — work to an existing party wall or party structure

Section 2 covers direct work to a shared wall. It is the most commonly triggered section and includes:

• Cutting into the party wall to insert a steel beam (common in loft conversions and chimney breast removals)
• Raising or lowering the party wall
• Demolishing and rebuilding the party wall
• Underpinning the party wall or the adjoining owner's wall
• Exposing the party wall by demolishing a building attached to it

You must serve a Section 2 notice (party structure notice) at least two months before work starts. For more on selling a property where structural alterations were involved, see our guide on selling a house with an extension.

Section 6 — excavation near neighbouring buildings

Section 6 applies when you excavate:

• Within three metres of a neighbouring building, where the excavation will go deeper than the bottom of the neighbour's foundations
• Within six metres of a neighbouring building, where the excavation would cut a 45-degree line drawn downwards from the base of the neighbour's foundations

Section 6 is frequently triggered by rear extensions with deep footings, basement conversions, and underpinning. A Section 6 notice must be served at least one month before work starts and must include plans showing the excavation depth relative to the neighbouring property's foundations.

What buyers' solicitors ask for and why

Party wall matters arise in conveyancing enquiries in two main ways. First, the TA6 Property Information Form requires you to disclose alterations and building work carried out during your ownership. When the buyer's solicitor reviews the form and sees that an extension or loft conversion was built, they will assess whether the Party Wall Act applied and raise enquiries accordingly.

Second, the local authority search often reveals a history of building or planning applications. If a building regulations application is linked to structural or boundary work, the solicitor will ask whether party wall notices were served.

Typically the buyer's solicitor will ask:

• Whether the Party Wall etc. Act 1996 applied to the building work
• Whether party wall notices were served on all affected adjoining owners
• Whether the adjoining owners consented in writing or whether surveyors were appointed
• For copies of any party wall notices, written consents, or party wall awards
• For the schedule of condition that formed part of any award
• Whether any damage was caused to the adjoining property and whether it has been made good
• Whether there is any ongoing or unresolved dispute with the adjoining owner

These enquiries frequently overlap with questions about building regulations sign-off and planning permission. If you built an extension, expect enquiries about all three simultaneously. Having all the documentation ready before you instruct a solicitor is the most effective way to keep the sale moving.

What to do if you have the party wall award

If the party wall process was followed correctly and you have the award and schedule of condition, you are in the best possible position. Here is what to do:

1. Locate the full award document. This includes the signed award itself, the schedule of condition (with photographs if prepared), and any plans referenced in the award. Check your files, your solicitor from the original purchase, and the party wall surveyor who acted at the time.
2. Confirm you have all adjoining owners covered. If your property shares a boundary with more than one neighbour, and the work affected more than one party wall, you should have an award or consent for each affected adjoining owner. A single award covering only one neighbour when two were affected will prompt further enquiries.
3. Provide the documents to your solicitor early. Include them in the property information pack from the outset. The earlier the buyer's solicitor has them, the fewer enquiries they need to raise.
4. Check for any follow-up documentation. If the award required the building owner to make good any damage to the adjoining property, confirm that this was done. If repairs were required, having evidence (for example a signed confirmation from the adjoining owner that the work was completed to their satisfaction) will prevent further enquiries.

What to do if you do not have a party wall award

This is one of the most common situations sellers find themselves in. Many homeowners carry out notifiable party wall work — particularly loft conversions and rear extensions — without realising the Act applies, or without following the formal notice process. When selling, you have three main options:

Option 1: Party wall indemnity insurance

This is the most widely used solution in conveyancing. A party wall indemnity insurance policy covers the buyer and their mortgage lender against the financial risk of the adjoining owner making a claim under the Act in the future. Policies are a one-off payment with no annual renewal. Typical costs are £50 to £300, depending on the property value and the type of work involved.

Key conditions for party wall indemnity insurance:

• The work must have been completed more than 12 months ago (insurers are generally unwilling to provide cover for very recent work)
• There must be no visible damage to the adjoining property that could be attributable to the work
• There must be no known or ongoing dispute with the adjoining owner about the work
• You must not have already contacted the adjoining owner about the party wall issue — doing so before the policy is in place can prevent the insurer from offering cover or may void an existing policy

Your solicitor arranges the policy and the seller typically pays the premium. Most mortgage lenders accept party wall indemnity insurance for work completed more than 12 months ago with no evidence of damage or dispute.

Option 2: Letter from the adjoining owner

If you are on good terms with the affected neighbour, you can ask them for a written letter confirming that they were aware of the work, have no objection to it, sustained no damage (or any damage was made good to their satisfaction), and have no outstanding claim or dispute relating to the work. This is not a formal party wall award, but many buyer solicitors will accept it as satisfactory evidence, particularly where the work was completed some years ago.

A neighbour letter is not legally binding in the same way as a statutory award. If the buyer's lender takes a stricter view, it may need to be combined with an indemnity insurance policy. Your solicitor can advise on this. Critically, if you are considering relying on indemnity insurance, speak to your solicitor before approaching the neighbour — contacting them first can jeopardise the insurance route.

Option 3: Retrospective party wall process

In rare or complex cases, it may be necessary to engage party wall surveyors retrospectively to produce an award. A surveyor can inspect the completed work, prepare a schedule of condition of the adjoining property now, and produce a formal award. This is the most expensive and time-consuming option, typically costing £1,000 to £3,000 and taking four to eight weeks. It is normally only pursued where:

• There is visible or alleged damage to the adjoining property
• The adjoining owner has raised a complaint or indicated they may pursue a claim
• The buyer's lender will not accept indemnity insurance given the specific circumstances

How the party wall award affects your sale timeline

When the party wall award is available and in order, it adds very little time to the conveyancing process. The buyer's solicitor reviews the documents, is satisfied, and moves on. The problem only arises when the documentation is missing or incomplete.

Here is how the issue typically plays out when there is no award:

1. The buyer's solicitor identifies the gap. Usually during review of the TA6 form or local authority search, they identify that notifiable work was carried out without a party wall award or consent on file.
2. They raise a pre-contract enquiry. They will ask your solicitor to confirm whether the Act applied and, if so, to provide the party wall award or an explanation of why one does not exist.
3. Your solicitor proposes a solution. This is typically indemnity insurance, supported where possible by a letter from the adjoining owner confirming no damage or dispute.
4. The buyer's lender reviews the position. If the buyer has a mortgage, the lender must also be satisfied. Most lenders accept indemnity insurance for party wall matters completed more than 12 months ago.
5. The sale proceeds (or is renegotiated). In the vast majority of cases, the issue is resolved with indemnity insurance and the sale completes without further difficulty. In a small minority of cases — where there is damage, an active dispute, or the lender's requirements are particularly strict — there may be a price renegotiation or a request to resolve the matter before exchange.

The key lesson for sellers is that the earlier you identify and address the issue, the less impact it has on your timeline. Arranging indemnity insurance through your solicitor typically takes two to five working days. Waiting for the buyer's solicitor to raise it adds weeks of enquiry and response time on top of that. This type of upfront preparation is exactly what Pine helps sellers tackle before listing, so that the legal pack is ready when a buyer arrives. See our guide on the hidden costs of selling a house for more on the expenses that often catch sellers by surprise.

Party wall awards and boundary disputes

Party wall and boundary issues are closely related but distinct. The Party Wall Act deals with work on or near a shared wall or boundary — it does not resolve disputes about where the boundary actually lies. If there is an unresolved question about the exact position of the boundary between your property and a neighbour's, that is a separate matter covered by boundary dispute rules.

A party wall award may reference the boundary line, particularly in Section 1 cases involving building on the boundary, but it does not determine or conclusively fix the boundary for title purposes. The boundary remains a matter of title deeds and the Land Registry title plan. When selling, if there is both a party wall issue and an unresolved boundary question, your solicitor will need to address them separately.

Disclosing party wall matters on the TA6 form

The TA6 Property Information Form is the cornerstone of the seller's disclosure obligations in England and Wales. It asks about alterations, building work, disputes, and complaints. Party wall matters are relevant to several sections:

• Alterations section: You must disclose structural or significant building work carried out during your ownership, including extensions, loft conversions, chimney breast removals, and significant excavation. The buyer's solicitor will use this to determine whether the Party Wall Act applied.
• Disputes and complaints section: Any dispute with a neighbour about building work, access, or damage — even one that has been resolved — must be declared. Concealing a known dispute can give the buyer grounds for a misrepresentation claim after completion.
• Notices section: If any formal notices were served on you or served by you (for example, a party wall notice or a response to one), this is relevant to the notices section.

Be honest and complete in your answers. If work was done without the proper party wall process, say so. Your solicitor can then plan the appropriate solution before the buyer's solicitor raises it, which is always a better position than reacting to a formal enquiry midway through conveyancing.

Common party wall scenarios sellers encounter

Practical tips for sellers

1. Audit your building work history early. Before you list your property, identify all significant building work carried out during your ownership — extensions, loft conversions, chimney breast removals, basement works. For each, consider whether the Party Wall Act applied and whether you have the necessary documentation.
2. Locate your party wall documents. If notices were served and an award was produced, find the original award and its schedule of condition. Your party wall surveyor and your conveyancing solicitor from the original works may hold copies.
3. Decide on indemnity insurance before contacting the neighbour. If no party wall award exists and you are considering indemnity insurance as the solution, speak to your solicitor before approaching the adjoining owner. Contacting the neighbour about the party wall issue can make the policy unavailable.
4. Disclose accurately on the TA6 form. Honest disclosure allows your solicitor to prepare solutions in advance. Trying to conceal party wall issues creates far greater risk — both in terms of the sale stalling and potential legal exposure.
5. Address it before you list. Party wall indemnity insurance can be arranged in days. Dealing with this before finding a buyer means it never becomes a negotiating point or a cause of delay during conveyancing.
