Party wall notices

How much does a party wall notice cost in London?

The notice is a small fixed fee per neighbour. What it sets going is the part that can cost more.

What the notice does

The Party Wall etc. Act 1996 lets you carry out certain work to a shared wall or near a neighbour’s foundations, if you serve the right notice first. Our fee is £42 for each adjoining owner, so a terrace with two neighbours is two notices.

We write each one from the drawings, so the description of the work matches what is built.

What a measured survey recordsA plan of a house and its rear garden with the things a measured survey records: room dimensions and wall thicknesses inside, floor-to-ceiling heights, levels taken from one datum, the boundary line, a drain manhole, a tree near the boundary, and the neighbour’s rear window with the 45-degree line drawn from it.BoundaryRoom sizesCeilingheightsWallthickness45° line from theneighbour’s windowDatumDrainTree

Which notice, and how long before work

A party structure notice, for work such as cutting into the wall to seat a beam, must be served at least two months before the work begins. A notice to build a new wall on the line of junction needs one month. Deep excavation near a neighbour needs one month’s notice where it is within 3 metres of their building and deeper than their foundations, or within 6 metres on a 45-degree line.

If your neighbour does not agree

Silence is not consent. If the neighbour does not consent within fourteen days, they are deemed to dissent and a dispute is deemed to have arisen. Under section 10 both parties then appoint one agreed surveyor, or each appoints one and the two choose a third.

Surveyors charge fees for their work, which is a cost beyond our notice fee. A friendly word with the neighbour, and a copy of the drawings, often avoids it.

By the numbers

Party wall notices: common questions

Is the surveyor’s fee included?

No. Our fee is for the notice. A surveyor’s fee arises only if a dispute does.

Do I need a notice for every neighbour?

For each adjoining owner affected, yes. We count them on the survey.

Can I start early if my neighbour agrees by word of mouth?

No. The Act works through written notices and consent, so wait for the written reply.
