Anyone may be the surveyor who settles a party wall dispute and its cost.
Section 20 of the Party Wall etc. Act 1996 defines a surveyor entirely by what he is not: “any person not being a party to the matter” appointed under section 10. No register, no examination, no licence, no regulator. Section 10(13) then leaves the reasonable costs of the award to be paid by whichever parties the surveyors themselves determine, and section 10(16) makes the award conclusive. Meanwhile Parliament spent 2024 making it a criminal offence under section 58X of the Building Act 1984 merely to pretend to be a registered building control approver.
When someone in England or Wales digs foundations, cuts into a shared wall or builds near a neighbour’s, the law makes them tell the neighbour first. If the neighbour objects, the two households do not go to court. Instead each side names a surveyor, and those surveyors — not a judge — decide in a binding document what work may happen, on what terms, and who pays for the paperwork. This edition is about who is actually allowed to be that surveyor, and what the job is worth.
Read the definition again as a market, not as a drafting curiosity. Section 20 says “surveyor” means “any person not being a party to the matter appointed or selected under section 10 to determine disputes in accordance with the procedures set out in this Act.” That is the whole qualification. The Act names no professional body, prescribes no competence, keeps no register and gives no regulator a view. The only disqualification in the entire statute is being one of the two neighbours.
Now stack the powers that definition carries. Section 10(1) gives the owners a choice of one agreed surveyor or two party-appointed ones who then select a third. Section 10(2) requires every appointment to be in writing and says it may not be rescinded by either party — so the person who appointed you cannot sack you. Section 10(4) goes further: if an owner refuses to appoint, or fails to do so within ten days of a request, the other side may appoint on his behalf. Section 10(12) lets the award decide “the cost of making or obtaining an award”. Section 10(13) says the reasonable costs of the award, of inspections, and of other dispute-related matters are borne by whichever parties the surveyors determine. Section 10(16) makes the award conclusive and unimpeachable in court. Section 10(17) leaves exactly one exit: fourteen days, to the county court, for £175.
So the office is unlicensed, the appointment is irrevocable, the fee is set inside the award by the officeholder, and the award is final unless somebody pays a court fee inside a fortnight. That combination does not exist anywhere else in English property practice, and the contrast being drawn next door is what makes it a pattern break rather than a quirk. From 6 April 2024, under the Building Safety Act 2022 regime, working as an unregistered building inspector is a criminal offence, classes 2 and 3 require a competency assessment repeated at least every four years, and section 58X criminalises impersonating a registered building control approver at all. Parliament regulated the person who checks the drawings and left the person who decides the money alone.
The liability side was tested this summer, and the answer came back in the surveyors’ favour. On 11 June 2026 Mrs Justice O’Farrell struck out a claim pleaded at £1,503,818.00 against, among others, two named party wall surveyors — Tim Cook, appointed by the building owner’s company by letter of 11 January 2024, and David Randall, appointed by the claimant under section 10 by letter of 31 January 2024 — arising from works that damaged and ultimately part-demolished the house next door. Quoting earlier authority, the judgment records that “the surveyors are not assuming a design obligation towards the adjoining owner” and that “the statutory procedure is intended to be a simple, inexpensive dispute resolution mechanism.” A £1.5m claim against the two adjudicators disclosed no reasonable grounds.
Here is the part nobody prices. The constraint on this route is not capacity and not the fee — it is origination. At the judiciary’s own Guideline Hourly Rates for 2026, approved by the Master of the Rolls Sir Geoffrey Vos and in force since 1 January 2026, the whole annual target of £44,589.77 is 222.95 chargeable hours at the National 2 grade C rate of £200, or 77.01 hours at London 1 grade A’s £579. That is 4.29 hours a week, or 1.48. Raising your fee per appointment does not change that number at all; it only changes how many neighbours you must find. And the supply side is thinner than it looks: against 145,600 householder planning decisions in England in the year to June 2026, the Companies House register carries 57 companies with “party wall” in the name.
The evidence
14 findingsA surveyor is “any person” who is not one of the two neighbours.
Section 20 interpretation: “‘surveyor’ means any person not being a party to the matter appointed or selected under section 10 to determine disputes in accordance with the procedures set out in this Act.” That is the complete definition. The Act creates no register, names no professional body, prescribes no qualification or competence standard, and gives no regulator any function over who may hold the office. Legislation.gov.uk records “no known outstanding effects” for section 20. The only other appointment provision is the “appointing officer”, defined in the same section as the person appointed by the local authority to make the appointments required under section 10(8). Section 20
Once appointed you cannot be sacked, and the other side can appoint for you after 10 days.
Section 10(1): the owners either “concur in the appointment of one surveyor” or each appoints one and those two select a third. Section 10(2): every appointment or selection must be in writing and “shall not be rescinded by either party”. Section 10(4): where a party refuses to appoint, or fails to do so within ten days of being requested, the other party may make the appointment on his behalf. Section 10(8): if a party-appointed surveyor refuses or fails to select the third surveyor, the local authority’s appointing officer may do it on application. The appointment is therefore both forceable and irrevocable — a combination that exists in very few other offices open to anybody. Section 10
The surveyors decide who pays, and the award is conclusive.
Section 10(12) lets the award determine the right to execute work, the time and manner of it, and other incidental matters “including the costs of making or obtaining an award”. Section 10(13): the reasonable costs of making or obtaining the award, of reasonable inspections of work, and of any other matter arising out of the dispute “shall be paid by such of the parties as the surveyor or surveyors making the award determine”. Section 10(16): the award is conclusive and shall not be questioned in any court, except as provided by section 10. Section 10(17): either party may appeal to the county court within fourteen days of service, and the court may rescind or modify the award and make any order as to costs. The word doing the work in 10(13) is reasonable, and the fourteen days is the only window in which anyone tests it. Section 10
Next door, pretending is already a criminal offence.
Section 58X, “Offence of pretending to be a registered building control approver”: a person who is not a registered building control approver commits an offence if, with intent to deceive, the person impersonates one, or “does anything (including using any name, title or description)” implying that the person is one. Punishable on summary conviction by a fine. Part 2A of the Building Act 1984 was inserted by section 42 of the Building Safety Act 2022 and commenced in stages between 6 April 2023 and 6 April 2024. Read this row against the first one: the statute book now protects the title of the person who checks the drawings, and leaves wide open the office of the person who decides the money. Section 58X
Building inspectors must requalify every four years. Party wall surveyors never qualify.
The Building (Registered Building Control Approvers etc.) (England) Regulations 2024, made 28 January 2024, laid 1 February 2024, in force 6 April 2024, signed by Lee Rowley, Minister of State, Department for Levelling Up, Housing and Communities. Regulation 31 sets the prescribed registration period at four years for registered building inspectors and five for registered building control approvers; regulation 3 bars an approver from a professional or financial interest in work it supervises; regulation 34 gives a right of appeal to the First-tier Tribunal. The department’s own guidance states that “if you are not registered it is a criminal offence to work as a building inspector”, that class 1 inspectors may work only under supervision, and that classes 2 and 3 “must complete a competency assessment from an approved scheme”, repeated at least every four years.

The court’s own price for an hour runs £142 to £579.
Guideline Hourly Rates 2026, approved by the Master of the Rolls, Sir Geoffrey Vos, Head of Civil Justice, implementing the Civil Justice Council’s recommendation, effective Thursday 1 January 2026 and 2.28% above the 2025 rates on service producer price inflation to Q1 2025. Grade A: London 1 £579, London 2 £422, London 3 £319, National 1 £295, National 2 £288. Grade B: £393, £327, £262, £247, £247. Grade C: £305, £276, £209, £201, £200. Grade D: £210, £157, £146, £142, £142. These are the rates a county court reaches for when it is asked whether a cost was reasonable — which is the exact question a section 10(17) appeal puts to it about a section 10(13) determination.

Two named surveyors struck out of a £1,503,818.00 claim.
Gunaratnam Kirupakaran v Mahomed Tehseen Ibrahim & Ors, case HT-2025-000277, Technology and Construction Court, before Mrs Justice O’Farrell DBE, heard 4 June 2026 and handed down 11 June 2026. Structural works at 164 Croydon Road, SE20 damaged the claimant’s 166, which was later partly demolished; losses were pleaded at £1,503,818.00 to 2 July 2025. Among the defendants were the two party wall surveyors: Tim Cook, appointed by MYK Properties Holding Ltd by letter of 11 January 2024 (para 55), and David Randall, appointed by the claimant under section 10 by letter of 31 January 2024 (para 67). All four strike-out and summary judgment applications were granted. The judgment records at para 62 that “the surveyors are not assuming a design obligation towards the adjoining owner” and that “the statutory procedure is intended to be a simple, inexpensive dispute resolution mechanism”; the First Award itself provided that “the Two Surveyors shall not be held accountable for any defective design or specification” (para 63). Security of £30,000 was provided under clause 9 of the Second Award (para 69). Kirupakaran v Ibrahim
One third surveyor awarded £381,189.82. The Court of Appeal cut it by 20.77%.
Robert Taylor v Peter Jones & Anor, Court of Appeal, Macur LJ, Bean LJ and Nugee LJ giving the leading judgment, on appeal from HHJ Backhouse in the County Court at Central London. Garden excavation at 9 St George’s Terrace; the third surveyor Rob French made awards under section 10(11) which the building owner appealed under section 10(17). The awards ran to £189,727.12 and £142,105.62 excluding VAT — £215,316.28 and £165,873.54 including it — and para 28 records that they included “the adjoining owners’ surveyor’s referral costs, and his own fees”. The judge below cut them to £147,540.01 and £115,361.88 ex VAT; the Court of Appeal then allowed ground 2, holding the building owner not liable for underpinning that remedied a pre-existing defect, and remitted quantum. Ground 1 on costs was dismissed and the 75% costs order stood. This is the other side of the trade: two surveyors, acting under a statute that asks them for no qualification, directed £381,189.82 between neighbours, and most of a decade of litigation followed. Taylor v Jones
The only published per-dispute fees: £2,140 and £2,400, plus VAT.
Mirimskaya v Evans & Anor, before Richard Fernyhough QC sitting as a Deputy High Court Judge. Under the heading “Party Wall Surveyors’ Fees” at para 68 the judgment records “£2,140 plus VAT in respect of the fees of Boyle & Co” and “the sum of £2,400 plus VAT in respect of the fees of Dunphy & Hayes” — two surveyors, one dispute, £4,540 plus VAT between them. The judge expressly declined to rule on reasonableness, saying “without deciding the point, on the face of it” the fees “would appear to be payable since they represent the fees of Chartered Surveyors who dealt with and finally agreed the Party Wall Awards.” These figures are nineteen years old and are the weakest evidence on this page. A full-text search of the National Archives’ Find Case Law for “party wall surveyor’s fees” returns this judgment and nothing else. Mirimskaya v Evans
145,600 householder decisions in a year, 90% granted.
Planning applications in England, April to June 2026: 37,700 householder development decisions in the quarter, about 51% of all decisions, of which 91% were granted; 145,600 in the year ending June 2026, about 50% of all decisions, of which 90% were granted. Householder development is the extension, loft conversion and basement category — the work that triggers notices under sections 1, 2 and 6 of the Party Wall etc. Act. Figures are rounded to the nearest hundred in the release; unrounded ones sit in the live tables.

The only gate anyone pays is £175, and the other side pays it.
HM Courts and Tribunals Service fee list EX50A, July 2026: an appellant’s or respondent’s notice in the county court costs £175 on other claims, fee 2.3(b), code FEE0405, or £151 on small claims, fee 2.3(a), code FEE0406. That is the price of the section 10(17) appeal, and it falls on whoever is unhappy with your award, not on you. Nothing in the Party Wall etc. Act charges a surveyor anything. If you incorporate, Companies House charges £100 to register a company online or by software, £124 on paper, and £50 for the annual confirmation statement filed digitally. You do not need to: section 20 says “any person”. EX50A · Companies House fees
£1 = $1.3456, 1–31 October 2026.

222.95 hours a year. 19 appointments. Neither depends on the other.
$500 ÷ 1.3456 = £371.58. $5,000 ÷ 1.3456 = £3,715.81 a month, × 12 = £44,589.77 a year. Hours at the 2026 Guideline Hourly Rates: £44,589.77 ÷ £579 = 77.01 h/yr, 1.48 a week, at London 1 grade A; ÷ £247 = 180.53, 3.47 a week, at National 1 grade B; ÷ £200 = 222.95, 4.29 a week, at National 2 grade C; ÷ £142 = 314.01, 6.04 a week, at grade D. Appointments: £44,589.77 ÷ £2,400 = 18.58 a year; ÷ £2,140 = 20.84; ÷ £4,540 = 9.82. Hours per appointment at £200/hr: £2,400 ÷ 200 = 12.00. Capacity: 1,600 h ÷ 12 h = 133.33 appointments, so the target is 18.58 ÷ 133.33 = 13.93% of one practitioner’s year — and because hours = target ÷ rate, the hours figure is independent of the fee entirely. Market density: 145,600 ÷ 18.58 = one appointment in every 7,837 householder decisions, 0.01276%; 145,600 ÷ 57 companies = 2,554 decisions per named company; 90% of 145,600 = 131,040 granted. Costs against the target: £175 = 0.39% of a year and 7.29% of one £2,400 fee; £371.58 of capital = 15.48% of one such fee; £100 + £50 = £150 leaves £221.58. Scale check: the Taylor v Jones awards of £381,189.82 including VAT are 8.55 years of the target; the Kirupakaran pleaded loss of £1,503,818.00 is 33.73 years of it. HMRC’s VAT registration threshold is £90,000, so the target is 49.54% of it with £45,410.23 of headroom. Diagram: x = 92 + 0.132444 × (fee − 500); the hours line sits at y = 320 − 264 × 222.9489 ÷ 350 = 151.83.

From $500 to $5,000 a month · £374 → £3,738$500 is £371.58 at HMRC’s October rate, and the Party Wall etc. Act 1996 does not want any of it. There is no application, no examination, no registration fee and no body to apply to, because the Act defines the office by exclusion: any person who is not one of the two neighbours. Everything written about becoming a party wall surveyor assumes a gate. Go and look for it in the statute first; you will not find one.

Do not spend the capital on a company.
Companies House charges £100 to incorporate online and £50 a year for the confirmation statement — £150 of the £371.58, leaving £221.58. Section 20 says “any person”, and a named individual is who gets appointed in the letters the courts quote. Aspen Party Wall Surveyors Ltd is a real filed example of the corporate route, incorporated by a twenty-two-year-old in 2019 and still filing; it is a convenience, not a requirement. Buy the time, not the certificate.

Understand that the appointment is a one-way door.
Section 10(2): an appointment is made in writing and “shall not be rescinded by either party”. Section 10(4): if the other owner will not appoint, your side may appoint for him after ten days. No other service relationship in English property works this way — the client cannot fire you and the counterparty cannot refuse to be represented. This is the structural fact the whole route rests on, and it is three subsections long.
s.10(2) irrevocable · s.10(4) forceable after 10 days -
Price the award, and price it against the judiciary’s own table.
Section 10(13) hands the reasonable costs of the award to whichever parties the surveyors determine. The adjective is load-bearing. Reasonableness is tested, if at all, in a county court under section 10(17), and the county court’s own benchmark since 1 January 2026 is the Guideline Hourly Rates: £200 an hour for a National 2 grade C fee earner, £579 for London 1 grade A. Record your hours as though a district judge will read them, because that is the only reader who can touch the number.

Count neighbours, not hours.
£44,589.77 a year is 222.95 chargeable hours at £200, or 77.01 at £579. That figure does not move when you change your fee per appointment, because an appointment at twice the fee is twice the work at a fixed rate. What moves is the count: nineteen appointments a year at Mirimskaya’s £2,400, twenty-one at its £2,140. The target is 13.93% of one person’s working year. Origination is the entire job.

Watch the two ways it actually fails.
First, jurisdiction: the section 10 machinery only runs where the Act is engaged, and the surveyors’ powers are statutory, not general. Second, quantum: in Taylor v Jones a third surveyor’s awards of £381,189.82 including VAT were cut by a county court and then partly unwound by the Court of Appeal in February 2024. What does not seem to fail is personal exposure — in June 2026 the TCC struck two named surveyors out of a £1.5m claim, holding they assumed no design obligation to the adjoining owner.

Nineteen appointments is one in every 7,837 extensions.
England decided 145,600 householder planning applications in the year to June 2026 and granted 90% of them. Nineteen appointments is 0.01276% of that flow, and the Companies House register carries 57 companies with “party wall” in the name — 2,554 householder decisions apiece. At £44,589.77 you also sit at 49.54% of the £90,000 VAT registration threshold, with £45,410.23 of headroom before that arithmetic changes.
