Schedule of Condition Guide for UK Homeowners (2026)

A schedule of condition is a detailed photographic and written record of the current state of a neighbouring property's walls, ceilings, floors, and other structural elements before building work begins. It is prepared by a party wall surveyor under the Party Wall etc. Act 1996 and forms part of the party wall award.

The purpose is to create an objective baseline. If the neighbour claims damage after your building work, the schedule of condition is the evidence used to determine whether the damage is new or pre-existing.

Crown Party Wall Surveyors prepares schedules of condition for homeowners across London, Kent, Essex, Surrey, and Hertfordshire.

A schedule of condition is required or strongly recommended whenever:

Even if the Party Wall Act does not strictly apply, a precautionary schedule of condition can protect you from unfounded damage claims.

• Party wall notice served and award being prepared — yes, standard part of the award
• Extension being built against or near a party wall — yes
• Loft conversion involving a party wall or party structure — yes
• Basement or underpinning work near a party wall — yes
• Chimney breast removal on a party wall — yes
• Demolition adjacent to a neighbour — yes
• No party wall trigger but vibration-heavy work nearby — recommended (precautionary)

A thorough schedule of condition typically records:

Each defect is described with its location, size (where measurable), and character (e.g., hairline crack, stepped crack, settlement crack, shrinkage crack).

• External walls — cracks, pointing condition, staining, render condition
• Internal walls — cracks (mapped with measurements), plaster condition, decorative finishes
• Ceilings — cracks, staining, sagging, cornice condition
• Floors — cracking, unevenness, tile condition
• Windows and doors — frame condition, operational state, glazing
• Staircases — structural condition, creaking, visible damage
• Drainage (where accessible) — visible condition, any existing blockages
• Garden and boundary walls — lean, cracking, pointing
• Photographs — date-stamped, room-by-room, with close-ups of existing defects

The schedule of condition is prepared by one of the following:

In practice, the party wall surveyor(s) will arrange access, conduct the inspection, and include the schedule of condition within or annexed to the party wall award.

• Agreed surveyor — when both the building owner and adjoining owner agree to appoint a single surveyor
• Adjoining owner's surveyor — when each party appoints their own surveyor, the adjoining owner's surveyor typically inspects the adjoining owner's property
• Building owner's surveyor — may prepare the schedule if access is granted and it is part of the award

The schedule of condition is prepared through a structured five-step process, ensuring a thorough and impartial record.

Indicative schedule of condition fees for common property types in 2026:

Costs vary depending on the property size, number of rooms, and complexity. The building owner typically pays for the schedule of condition as part of the party wall award costs.

• Flat or maisonette (one side only) — £400 to £800
• Terrace house (one adjoining owner) — £500 to £1,000
• Semi-detached house (one adjoining owner) — £500 to £1,000
• Detached house with boundary wall only — £300 to £600
• Multiple adjoining owners (terrace with both sides) — £800 to £1,500+

Under the Party Wall etc. Act 1996, the building owner (the person carrying out the works) is generally responsible for the reasonable costs of the party wall process, including the schedule of condition.

This includes the surveyor's fee for preparing the schedule, any travel or access-related costs, and the cost of including the schedule in the award.

The adjoining owner does not normally pay for the schedule of condition.

• The surveyor's fee for preparing the schedule
• Any travel or access-related costs
• The cost of including the schedule in the award

If the adjoining owner notices new damage during or after the building work, the schedule of condition is used to determine responsibility:

This is why a thorough and accurate schedule of condition protects both parties.

• They report it to the party wall surveyor(s).
• The surveyor(s) inspect the reported damage.
• The schedule of condition is used to compare the current state with the pre-works baseline.
• If the damage is new and attributable to the building work, the building owner is responsible for making good or compensating the adjoining owner.
• If the damage is pre-existing (already recorded in the schedule), the claim is not upheld.

The adjoining owner has a right to privacy, but the Party Wall etc. Act 1996 provides a framework for resolving access disputes. If access is refused:

Most adjoining owners cooperate because the schedule of condition also protects their interests.

• The surveyor should write formally requesting access.
• If still refused, the surveyor may record the condition from available vantage points (exterior, boundary, etc.) and note in the award that access was not granted.
• In extreme cases, the matter can be referred to the county court, but this is rare.

Even when the Party Wall Act does not apply (e.g., works near but not on the boundary), a precautionary schedule of condition is often worthwhile.

A precautionary schedule follows the same process but is a standalone document rather than part of a party wall award.

• Piling or heavy groundworks near a neighbour
• Demolition works with significant vibration
• Deep excavation near a boundary
• Works involving heavy plant near existing structures
