Party Wall Award Timeline: How Long the Process Really Takes

How long does a party wall award take? As a general picture of the market, allow roughly six to twelve weeks from serving notice to holding a signed award where the neighbour dissents and surveyors are appointed, and longer for basements or where several adjoining owners are involved. The statutory notice period alone is one or two months, the adjoining owner has 14 days to respond, and the surveyors then need time to agree the drawings, record a schedule of condition and draft the award. This guide walks through each stage of the party wall process, the deadlines fixed by the Party Wall etc. Act 1996 and the points where the timetable most often slips.

The statutory clock: notice periods under the 1996 Act

Everything starts with a valid notice, and the Act sets a minimum period between service and the start of works. A section 3 party structure notice (cutting into, raising or underpinning a shared wall) must be served at least two months before the works begin. A section 1 line of junction notice (building a new wall at or astride the boundary) and a section 6 adjacent excavation notice (digging within three or six metres of a neighbour's foundations) each need at least one month.

Those periods are minimums, not targets. The adjoining owner can agree in writing to waive them, and in practice the award rather than the notice period usually dictates when a builder can start. A party structure notice also has a shelf life: under section 3(2)(b) it ceases to have effect if the works have not begun within twelve months of service, so serving far too early can mean serving again. Our guide to party wall notices explains what each type must contain, and the free party wall notice generator produces the wording.

Stage one: the 14-day response window

Once a section 3 or section 6 notice is served, the adjoining owner has 14 days to consent in writing. If they do nothing, section 5 treats them as having dissented and a dispute is deemed to have arisen.

• Consent within 14 days: no award is needed. The building owner can start once the notice period has run (or sooner with written agreement). Most surveyors still recommend a schedule of condition, which adds a week or so for an inspection and a short report, but it protects both sides if damage is alleged later.
• Dissent, or silence for 14 days: the matter moves to section 10 and the award timetable below applies.

Building owners often lose time here by serving notice before their drawings are finished. A neighbour cannot sensibly consent to works they cannot see, and surveyors cannot draft an award from a planning sketch. Serve the notice with the structural drawings and the method statement attached and the rest of the process moves faster. Our guide on what happens when a neighbour refuses covers the dissent route in more detail.

Stage two: appointing the surveyors

Under section 10 the owners either agree on a single agreed surveyor or each appoint their own, and the two appointed surveyors must then select a third surveyor straight away in case they disagree. Appointments must be in writing and cannot be rescinded.

The Act contains two ten-day provisions that stop one side stalling. If an owner refuses or neglects to appoint a surveyor for ten days after a written request, the other owner may appoint one on their behalf. If an appointed surveyor refuses or neglects to act effectively for ten days after a written request, the other surveyor may proceed alone and produce the award. Used properly, these provisions mean an unresponsive neighbour delays matters by weeks rather than months.

An agreed surveyor is the quickest route: one inspection, one set of correspondence, one signature. Two surveyors generally add two to four weeks because drafts, drawings and the schedule of condition pass between them. Our guide to how to get a party wall agreement explains how to choose between the two routes.

Stage three: schedule of condition and drafting the award

With appointments in place, the surveyors review the structural drawings, raise queries with the building owner's engineer and arrange access to the adjoining property to record a schedule of condition. The award itself is then drafted, checked by the second surveyor where there is one, agreed and signed.

From dissent to signed award, a straightforward loft conversion or rear extension with an agreed surveyor is commonly completed in four to six weeks. Two-surveyor matters more often run to six to ten weeks. Basement excavations, underpinning and works affecting several adjoining owners can take three months or more, because the engineering has to be checked, monitoring regimes agreed and sometimes security for expenses under section 12 negotiated. A worked example of what the finished document contains is in the sample party wall award, and what is a party wall award explains each clause.

Stage four: service of the award and the 14-day appeal

The signed award is served on both owners and takes effect immediately. Either owner may appeal to the county court within 14 days of service under section 10(17); after that the award is conclusive and cannot be questioned in any court. Surveyors' fees, which the award normally places on the building owner, fall due on service. Most awards also carry a commencement clause, typically requiring the works to start within twelve months, after which a fresh award may be needed.

Once served, the building owner can begin the notifiable works provided the statutory notice period has also expired or been waived. Appeals are rare and usually concern fees or a specific condition; the expert witness guide to party wall appeals explains what the county court looks at.

What makes a party wall award take longer?

• Incomplete drawings. The single biggest cause of delay. Surveyors cannot award works that have not been designed.
• Several adjoining owners. A terraced house with neighbours on both sides, or a flat with freeholder and leaseholders, multiplies the notices, appointments and schedules.
• Silence from the neighbour. Costs at least 14 days plus the ten-day request period before an appointment can be made on their behalf.
• Access for the schedule of condition. Tenants, holidays and working hours all push the inspection date.
• Disagreement between surveyors. Referrals to the third surveyor are uncommon but add weeks.
• Design changes mid-process. A revised scheme may need an addendum award or, if the works change materially, a fresh notice.

Fees rise with time as well. As a general guide, an agreed-surveyor award for a typical domestic project costs around £1,000, two-surveyor awards from roughly £1,500, with hourly rates in the region of £100 to £250; our guide to who pays the party wall surveyor explains how the Act allocates those costs.

The quickest awards share the same habits: drawings finished before notice is served, a conversation with the neighbour before the letter lands, all notices served together with proof of service, an agreed surveyor proposed at the outset, and a builder booked for a start date that allows for the award rather than assuming it.
