Planning a loft conversion, rear extension, or basement dig in Surrey? If your works affect a shared wall, boundary structure, or your neighbour's foundations, you will need to comply with the Party Wall etc. Act 1996. Esher Surveyors handles party wall matters across Esher, Cobham, Weybridge, and the wider Surrey area every week – and this guide explains everything you need to know about costs, timelines, and the process from start to finish.
What Is the Party Wall Act?
The Party Wall etc. Act 1996 is a piece of UK legislation that provides a framework for preventing and resolving disputes between neighbours in relation to party walls, boundary walls, and excavations near neighbouring properties. It applies across England and Wales.
The Act requires a building owner (the person doing the works) to give formal notice to all affected adjoining owners before certain types of construction work can begin. It is a mandatory legal requirement – not optional. Failing to comply with the Act does not invalidate the works, but it exposes the building owner to injunctions and potential damages claims.
When Does the Party Wall Act Apply?
Three types of work trigger the Party Wall Act:
Section 1 – Building on or at the Boundary
New walls built on the line of junction between two properties, or within 3 metres of the boundary where the foundation will be deeper than the adjacent building's foundation.
Section 2 – Works to an Existing Party Wall or Structure
This is the most common trigger and includes:
- Cutting into the party wall (e.g. for steel beams in loft conversions)
- Raising or extending the party wall
- Underpinning the party wall
- Demolishing and rebuilding the party wall
- Weather-proofing a party wall following demolition of an adjoining building
- Inserting a damp-proof course
Section 6 – Excavations Near Neighbouring Buildings
Excavations within 3 metres of a neighbouring building where the excavation will go deeper than their foundations, or within 6 metres where a line drawn at 45° from the bottom of the proposed excavation would cut through their foundations.
This commonly applies to basement excavations and deep footings for extensions.
The Party Wall Process Step by Step
Step 1: Identify Notifiable Works and Adjoining Owners
Before serving notice, establish exactly what works are planned and which neighbours are "adjoining owners" under the Act. This includes the owners of any property that shares a party wall or party fence wall, or whose property is within the relevant excavation distances. Tenants as well as freeholders may be adjoining owners.
Step 2: Serve Party Wall Notices
You must serve formal written notice on each adjoining owner. Notice periods are:
- Section 2 works (party wall works): Minimum 2 months' notice before work starts
- Section 6 works (excavations): Minimum 1 month's notice before work starts
- Section 1 works (new wall on boundary): Minimum 1 month's notice
Notices must be in writing and served personally, by post, or in some cases by other agreed means. Esher Surveyors can prepare and serve notices correctly on your behalf.
Step 3: Adjoining Owner's Response
Once notice is served, the adjoining owner has 14 days to respond. They have three options:
- Consent: They agree in writing. Works can proceed but the building owner must still take care to avoid damage and may be liable for any damage caused.
- Dissent and appoint a surveyor: The most common outcome. Both parties appoint surveyors (or agree to share one) who prepare a Party Wall Award.
- No response: Treated as dissent after 14 days. The building owner must then appoint a surveyor and the process continues.
Step 4: Appointment of Surveyors
Once in dispute, each party appoints their own surveyor. Alternatively, both can agree to appoint a single Agreed Surveyor – a cost-effective option when the relationship is amicable and the works are straightforward.
Esher Surveyors acts as both Building Owner's Surveyor and Adjoining Owner's Surveyor in party wall matters across Surrey.
Step 5: Schedule of Condition
The party wall surveyor(s) will prepare a Schedule of Condition – a detailed photographic and written record of the current state of the adjoining property before works begin. This is essential to establish any pre-existing defects and to provide evidence if damage is claimed after the works.
Step 6: Party Wall Award
The surveyor(s) prepare a Party Wall Award (also called a Party Wall Agreement) – a legally binding document that:
- Describes the works to be carried out
- Sets conditions for how works must proceed (hours, method, protection)
- References the Schedule of Condition
- Sets out the surveyor fees and who pays them
- Grants the right to access the adjoining property where necessary
Once the Award is served, works can begin (subject to notice periods having expired).
Typical Party Wall Timeline
Allow 6–8 weeks from first instruction to Party Wall Award in a straightforward case. Complex works, multiple adjoining owners, or contentious disputes can take 3–4 months. Plan your build programme accordingly – Esher Surveyors will give you a realistic timeline at your first consultation.
Party Wall Surveyor Fees in Surrey
Party wall surveyor fees are paid by the building owner (the person doing the works), unless the Award determines otherwise. Typical fees for Surrey residential matters:
| Service | Typical Fee Range |
|---|---|
| Notice preparation and service | £150 – £300 per notice |
| Schedule of Condition (per property) | £300 – £600 |
| Party Wall Award (Building Owner's surveyor) | £700 – £1,200 |
| Party Wall Award (Adjoining Owner's surveyor) | £700 – £1,500 |
| Agreed Surveyor (both parties, simple case) | £800 – £1,500 total |
| Post-works inspection | £200 – £400 |
Complex works, contentious disputes, or multiple adjoining owners will increase costs. Esher Surveyors provides transparent, fixed-fee quotes wherever possible.
Receiving a Party Wall Notice? What to Do
If you receive a party wall notice from a neighbour, you have important rights. The building owner is liable for any damage caused to your property by their works, but you need to protect your position proactively:
- Read the notice carefully: Check what works are proposed and the planned start date.
- Respond within 14 days: Consent or dissent. Do not ignore the notice.
- Appoint a surveyor: If you dissent, appoint your own surveyor. Their fees are paid by the building owner.
- Insist on a Schedule of Condition: This documents the current state of your property before works begin.
- Review the draft Award carefully: Your surveyor will ensure the Award adequately protects your interests.
As an adjoining owner, your fees for the party wall process are generally paid by the building owner. Contact Esher Surveyors immediately if you receive a party wall notice and are unsure how to respond.

Frequently Asked Questions
Party wall surveyor fees in Surrey typically range from £700 to £1,500 per surveyor for standard residential works. As the building owner, you pay both surveyors' fees in most cases. An Agreed Surveyor (where both parties share one surveyor) can reduce total costs to £800–£1,500 for a straightforward case.
You need to serve notice and obtain consent or an Award for notifiable works under the Act. This includes works to a shared wall, building at the boundary, and excavations within 3–6 metres of a neighbour's structure. Not all building work triggers the Act – consult Esher Surveyors if you are unsure whether your works are notifiable.
If a neighbour does not respond within 14 days, they are deemed to be in dispute. You must appoint a party wall surveyor. Your neighbour then has 10 days to appoint their own surveyor. If they fail to do so, your surveyor can act as Agreed Surveyor and proceed to award.
No. The Party Wall Act is not a veto. Your neighbour cannot use it to prevent you from carrying out lawful building works. What the Act does is provide a framework for managing the process, protecting both parties, and resolving damage claims. Complying with the Act protects you, not just your neighbour.
Usually yes, if your property is a semi-detached or terraced house. The steel beam installation (cutting into the party wall to bear the ridge beam) almost always triggers Section 2 of the Act. Even if the beam is entirely within your own property, you may still need to notify if works are within the party wall structure. Esher Surveyors can advise whether your specific works are notifiable.
The building owner (the person carrying out the works) pays both surveyors' fees in the vast majority of cases. There is an exception if the adjoining owner has acted unreasonably or has requested extra work beyond what is required to protect their interests. Fees are determined by the surveyors and set out in the Party Wall Award.
