Party wall surveyor fees in London are usually quoted per adjoining property, not per project, and they depend on how much of the process the case actually needs. Grey & Associates publish the whole schedule rather than quoting case by case: £165 plus VAT per notice, £620 plus VAT per Schedule of Condition, and £350 plus VAT per award acting for the Building Owner. A one-neighbour case that goes all the way to an award is £1,135 plus VAT.

Key takeaway

A one-neighbour party wall case with Grey & Associates is £1,135 plus VAT all-in — notice, one Schedule of Condition and the award. Where a dispute arises, that cost sits with the Building Owner, not the neighbour, because section 11 of the Party Wall etc. Act 1996 makes the person carrying out the work responsible for both sides' reasonable surveyor fees.

The fee is fixed before work starts and does not move if the case takes longer, which matters more in party wall work than in most things: the timetable is driven by notice periods, neighbours and other surveyors, none of which the building owner controls. The full figures follow, including what happens on a two-neighbour project and what basement work costs.

Our published fees

Standard party wall cases

  • Serving notice(s) — £165 + VAT per adjoining property
  • Schedule of Condition — £620 + VAT each
  • Award, acting for the Building Owner — £350 + VAT per adjoining property
  • Award, acting for the Adjoining Owner as agreed surveyor — no additional charge

All prices exclude VAT, charged at 20%. A separate notice, schedule and award applies to each adjoining property affected.

Basement and underpinning schemes

  • Serving notice — £250 + VAT per adjoining property
  • Schedule of Condition — £1,100 + VAT each
  • Award — £1,050 + VAT per adjoining property
  • Total — £2,400 + VAT per adjoining property

A separate fixed package. We read the structural drawings and method statement before quoting, because the scheduling and temporary works input is far greater than on an extension.

These are standard cases: extensions, loft conversions, side returns, beam insertions, underpinning-adjacent work and similar projects. Where a case falls outside them — a listed building with an estate freeholder, a multi-owner mansion block, a scheme with unusual temporary works — we will say so and quote it properly rather than stretch a standard figure over it. Nothing on this page is an offer, and a formal written quote follows a review of the plans and the proposed works.

The all-in figure, and exactly what is in it

For a house with one neighbour, where the case becomes a dispute and therefore needs the full process, the arithmetic is:

  • Notice to the adjoining property — £165
  • Schedule of Condition on the adjoining property — £620
  • Award acting for the Building Owner — £350
  • Total £1,135 plus VAT

That figure covers as many site visits as the case needs, all correspondence with you, with your neighbour and with any other surveyor involved, the schedule itself, and the award. If the case settles quickly and never reaches an award, the award fee falls away and you are not charged it. If the case runs six months, the fee does not rise — which is the entire point of a fixed fee rather than an hourly rate on work where the pace is set by other people.

The one exception is worth knowing about, because it surprises people. Time spent dealing with poor or defective workmanship, negligence, or a failure to comply with an award or consent is charged separately at £185 per hour plus VAT. The first two hours of time spent on normal and unavoidable damage to a neighbouring property are not charged for. In other words, the standard risks are inside the fee; the avoidable ones are not.

Why the number of neighbours drives the cost

This is the single most common surprise on a party wall quote, and it is worth understanding before comparing prices. Fees are per adjoining property, because each adjoining owner is a separate case with their own notice, their own record of condition, and their own award. A mid-terrace house has two neighbours on the shared wall. A house converted into flats may have several adjoining owners on one side.

On standard fees, a project with two adjoining properties both going to award works out as:

  • 2 notices at £165 — £330
  • 2 Schedules of Condition at £620 — £1,240
  • 2 awards at £350 — £700
  • Total £2,270 plus VAT

On a basement scheme at the published package rate of £2,400 plus VAT per adjoining property, the same two-neighbour project is £4,800 plus VAT. And where every adjoining owner consents, the picture changes completely: there is no dispute, so no surveyors are appointed and no award is needed. The remaining cost is the notice itself at £165 plus VAT per adjoining property. The expensive part of party wall work is not the surveying — it is the dispute.

Who pays the fees

Where a dispute has arisen, the Building Owner — the person carrying out the work — is responsible for all surveyors' fees, including those of the surveyor and any checking engineer appointed by the Adjoining Owner. This is the position the Act sets out in section 11, and it is not a matter of negotiation in the ordinary case.

Two consequences follow, and they are worth stating because they surprise people in opposite directions.

  • If you have received a notice, you are not funding your own representation. The cost of your surveyor and your Schedule of Condition sits with the neighbour doing the work. Many adjoining owners assume they must either accept the works or pay to fight them, and neither is the position the Act takes.
  • If you are building, the neighbour's side of the dispute is your cost. Budgeting for a party wall case means budgeting for both surveyors, not just your own — which is exactly why getting the notice and the schedule right at the start is cheaper than arguing later.

There is more on the mechanics on our main party wall surveyor page and in our page on party wall awards, where the costs provision in an award is explained.

Comparing quotes, and the low headline rate

Party wall quotes for the same project can differ by a factor of three, and the difference is almost never the surveyor's hourly rate. Four questions settle it.

  • Per adjoining property, or per project? A quote that looks cheap per project is expensive if it covers one neighbour and you have two.
  • Is the Schedule of Condition included? This is the most common place a low headline rate hides, and it is the document that decides damage disputes. A quote that excludes it has not priced the work that matters most.
  • Is it actually fixed? An estimate with an hourly rate behind it transfers the cost of a slow neighbour or a slow surveyor onto you. Fixed means fixed.
  • Is VAT in the figure? At 20%, this changes the comparison materially, and quotes that omit it are not comparable with quotes that include it.

Our guides to how party wall surveyor fees should really work and fixed price party wall surveyors go through this in more detail, and our page on choosing a party wall surveyor in London sets out the questions worth asking before appointing anyone.

To get a firm figure, we need the address, the drawings for the proposed works, a short description of the build, and whether notice has already been served. From those we will tell you how many adjoining owners are likely to be affected, which section of the Act applies, and what the case will cost — in writing, before anything starts.

Party wall surveyor fees — frequently asked questions

How much does a party wall surveyor cost in London?

Grey & Associates publish their fees rather than quoting case by case. Serving notice is £165 plus VAT per adjoining property, a Schedule of Condition is £620 plus VAT per property, and an award acting for the Building Owner is £350 plus VAT per adjoining property. A one-neighbour case where a dispute arises — notice, one Schedule of Condition and the award — is £1,135 plus VAT. Basement and underpinning work is priced as a separate fixed package.

Do I have to pay for my neighbour's party wall surveyor?

Where a dispute has arisen, yes — and it is a statutory position rather than a commercial one. Section 11 of the Party Wall etc. Act 1996 makes the building owner carrying out the work responsible for the reasonable fees of both sides' surveyors, including any surveyor and checking engineer appointed by the adjoining owner. The adjoining owner is not paying for their own representation in the normal case, and many people facing a neighbouring extension do not realise this.

Why do party wall surveyor quotes vary so much?

Four things account for most of the difference. Whether the quote is per adjoining property or per project — a house with two neighbours is two of everything. Whether the Schedule of Condition is included or charged separately, which is often where a low headline rate hides. Whether the fee is genuinely fixed or an estimate with an hourly rate behind it. And whether VAT is included in the figure quoted. Comparing two quotes without checking those four points compares nothing.

Is a fixed fee better than an hourly rate for party wall work?

For the client, a fixed fee removes the one risk they cannot control: how long a neighbour or a surveyor takes to respond. Party wall cases run on other people's timetables — notice periods, schedules, awards — and an hourly rate puts the cost of those delays on the building owner. A fixed fee agreed before the work starts means the figure does not move if the case runs longer than expected.

Does the fee change if the party wall case takes longer?

No. Our fixed fees are all-inclusive and cover as many site visits as the case needs, together with all correspondence with you, with your neighbours and with any other surveyor involved. There is no meter running on phone calls or emails. The one exception is time spent dealing with poor or defective workmanship, negligence, or a failure to comply with an award or consent, which is charged separately at £185 per hour plus VAT. The first two hours of time spent on normal and unavoidable damage to a neighbouring property are not charged for.

Are basement party wall fees different?

Yes, and they are published separately rather than quoted after the fact. Basement and underpinning work is priced as a fixed package of £250 to serve notice, £1,100 per Schedule of Condition and £1,050 for the award — £2,400 plus VAT in total per adjoining property. The figures are higher because the scheduling, temporary works, monitoring and engineering input are far greater than on a loft conversion, and we read the structural drawings and method statement before quoting.

Do I pay a surveyor if my neighbour consents to the work?

No. If the adjoining owner consents in writing there is no dispute, which means no surveyors need to be appointed and no award is needed — so the surveyor and award fees do not arise. The remaining cost is serving notice, at £165 plus VAT per adjoining property. Many building owners serve notice themselves at no cost, though a notice that relies on the wrong section or describes the works vaguely can be challenged, which is usually a false economy.

What do you need from me to quote?

The address, the drawings or plans for the proposed works, a short description of what is being built, and whether notice has already been served on any neighbour. From those we can tell you how many adjoining owners are likely to be affected, which section of the Act applies, and produce a formal written quote. Nothing is agreed and no notice is served until you have that quote in front of you.
