Can I do my own Schedule of Condition?

Technically yes — there's no statutory requirement that an SoC be prepared by a party wall surveyor — but evidentially weak. Owner-prepared SoCs are routinely challenged in damage disputes ('photos missed key areas', 'no measurement of existing cracks', 'date stamps unreliable'). Surveyor-prepared SoC carries the weight of independent professional opinion + is part of the binding Award. Always use the appointed surveyor — cost £385–£1,800 + VAT is a fraction of one disputed damage claim.

How long does the SoC remain valid?

SoC reflects condition at date of inspection — usually 2–8 weeks before works start. If works are significantly delayed (e.g. 6+ months from SoC to commencement) a refreshed SoC may be required, particularly if adjoining owner has done own works in the interim that change the condition (redecoration, new flooring, repairs). Builderr default: SoC inspection within 6 weeks of programmed start; refreshed if start slips beyond 4 months.

Does the SoC give me access to my neighbour's property after works?

Yes — the Award provisions covering post-works inspection (typical re-inspection clause) entitle the appointed surveyors to access the adjoining property at completion with reasonable notice (14 days under s8) to compare condition against the SoC + close out the Award. Adjoining owner cannot unreasonably refuse re-inspection — though scheduling is in their gift. Re-inspection is the route to formally close any open damage claim + discharge the building owner's indemnity.

What Is a Schedule of Condition in a Party Wall Award?

A Schedule of Condition (SoC) is a photographic + written record of the adjoining property's condition immediately before notifiable works start — typically 40–120 photographs for a London extension, 200–500 for a basement. Prepared by the appointed party wall surveyor + attached to the Party Wall Award. Cost £385–£1,800 + VAT included in surveyor fees. Provides the baseline against which any post-works damage claim is assessed.

What an SoC records

Photographic schedule: high-resolution images (typically 8–24 MP) of every internal + external surface visible from the adjoining property side likely to be affected — full elevations of the shared wall, ceilings + walls of all rooms abutting the shared structure, floor surfaces, decoration, joinery, glazing, externally the shared elevation + any visible parts of the building from the boundary. Each photograph numbered, dated + cross-referenced to a written schedule. Written schedule: room-by-room narrative recording (a) existing cracks (location, length, width — measured to mm); (b) decoration state (paint condition, wallpaper joints, age); (c) joinery state (skirting/architrave gaps, door frame deflection); (d) glass + glazing (any existing crazing, putty failure); (e) floor surfaces (existing scratches, gaps, level issues); (f) ceiling + cornice condition (existing hairline cracks, defects); (g) chimney breasts + shared wall features. Detail level proportional to risk — typical 3-bed Victorian terrace extension = 50–80 photos + 3–8 written pages; basement = 250–450 photos + 12–25 written pages including measured crack monitoring stations.

Why the SoC matters — damage claim mechanics

Without an SoC, post-works damage disputes become 'he-said/she-said': adjoining owner claims a crack appeared after the build; building owner claims it pre-existed. With an SoC: photographic evidence settles it. If a crack exists in the SoC it was pre-existing — adjoining owner has no claim. If it doesn't, building owner is on the hook for the cost of repair under s7 Act statutory liability + indemnity in the Award. Most London party wall damage claims are settled by reference to SoC without further dispute. Typical damage settlements: cosmetic crack repair £180–£950; cornice/plaster repair £450–£3,500; structural movement remediation £8,500–£75,000+. Insurance: building owner's contractor PL covers most claims if contractor at fault; building owner personal liability (per Award indemnity) for any uninsured damage. SoC is also valuable to the adjoining owner — provides evidence of legitimate damage they can pursue against a defensive building owner.

Best practice — building owner perspective

Builderr practice + recommendation to building owners: (1) treat SoC as mutual protection, not adjoining-owner luxury — push your surveyor for thorough SoC; (2) request walk-through of SoC photos with surveyor before exchange — confirm shared wall + neighbour's shared elevation fully captured; (3) for basements + structural underpinning, insist on measured crack monitoring stations (Avongard crack gauges fitted to existing cracks + measured weekly during works — read by neutral monitor); (4) for premium / sensitive interiors (period mouldings, fireplaces, original glass) supplement SoC with detailed close-ups + measured drawings — disputes over heritage feature damage can run £15,000–£85,000+ for plaster replication, marble repair, stained glass restoration; (5) commission post-works re-inspection of SoC at completion (typically £285–£850 + VAT) — agreed clean exit by appointed surveyors reduces post-build claim risk by ~80%; (6) where SoC reveals significant pre-existing defects, photograph + log carefully — these often become contested 'did the build make this worse' claims. SoC included in standard Award surveyor fee; the post-works re-inspection is typically a separately invoiced engagement.
