What it actually is
A Schedule of Condition is a written record — usually with photographs — of the state of a neighbouring property before your works begin. It covers visible features most likely to be affected by construction nearby: internal and external walls, ceilings, floors, existing cracks, damp, and anything already in poor repair. It is not a structural survey and doesn't assess whether a building is sound; it simply documents what it looked like on a given date.
Why it exists
Construction work — especially excavation, underpinning, or anything involving vibration — can cause or worsen cracking, settlement, or damp in an adjoining property. Without a Schedule of Condition, if a dispute arises later about whether your works caused damage, there's no independent baseline to compare against. Both sides end up arguing from memory and photographs taken after the fact, which rarely resolves anything quickly or amicably.
Do you need one if your neighbour consents?
This is the point most building owners get wrong. Consent to the works and a Schedule of Condition are two separate things. A neighbour can consent to your notice — meaning no Party Wall Award is needed — while still requesting, or you still offering, a Schedule of Condition as protection for both parties. It's common practice, and sensible practice, to arrange one even on a consented notice, particularly for anything involving excavation or work directly to a shared structure.
Where a neighbour dissents and a Party Wall Award becomes necessary, a Schedule of Condition is produced as a matter of course by the appointed surveyor(s) as part of that process.
Who arranges it, and who pays
On a dissented notice going to Award, the appointed surveyor(s) arrange the schedule as part of the award process, and the building owner typically bears the reasonable cost. On a consented notice where no surveyor is involved, either party can propose one informally — often at the building owner's initiative, as a way of reassuring a hesitant neighbour and protecting themselves against later, unfounded damage claims.
What it protects you from
A Schedule of Condition cuts both ways. For the adjoining owner, it's evidence if damage does occur. For the building owner, it's equally valuable — it protects you from a neighbour attributing pre-existing cracks or damp to your works after the fact, when in reality the condition long predates your project.
What this means for your notice
The platform's notice generator covers the statutory notice itself — the Schedule of Condition is a separate, optional step that sits alongside it. If your project involves excavation, underpinning, or direct work to a shared wall, it's worth arranging one regardless of how your neighbour responds to the notice, before work starts on site.
