Common questions
A party wall agreement costs roughly £150 to £2,500 in the UK, typically around £1,000. If your neighbour consents to the notice in writing, it can cost little more than serving the notice. If they dissent, a surveyor is appointed and the cost rises: one agreed surveyor is £700 to £1,200, or a surveyor for each side £1,000 to £2,500 or more, and that is per affected neighbour.
It can be. If you serve the correct notice and the neighbour agrees in writing, there is no surveyor cost and no formal award, just the notice itself. It only starts costing real money when a neighbour dissents, or fails to respond within 14 days, which counts as dissent, and triggers the surveyor process.
You can serve the notices yourself for free using the standard templates, and if the neighbour consents you may not need a surveyor at all. What you cannot do yourself is draw up the formal party wall award once there is a dispute: that has to be prepared by an appointed party wall surveyor, who acts impartially rather than for either side.
Generally the person doing the building work, the building owner, pays, and that usually includes the adjoining owner's surveyor fees as well, because the work is for your benefit. There are exceptions where the neighbour also benefits or causes delay, but the safe assumption when budgeting is that you cover both sides.
No. The party wall process is handled by party wall surveyors, not solicitors, and following it correctly keeps things out of the legal system. A solicitor only becomes relevant in the rare event of a serious dispute that escalates beyond the surveyors, which proper notices and a schedule of condition are designed to avoid.
You need one for work on or near a shared structure or boundary: cutting into a party wall (for a beam or a chimney breast removal), building on the boundary line, or excavating foundations within three to six metres of a neighbour's building. You must serve notice on the affected neighbours, usually two months before work starts, so factor it into your timeline early.
These are independent guide prices based on typical UK jobs in 2026. Your actual cost depends on your property, spec, access and where you live. Always get at least three written quotes before committing.
