Get party wall notices sorted before you alter your flat

Cutaway of a three-storey block of flats with the shared party wall and the floors between flats picked out in teal

For flat owners and leaseholders in England and Wales planning structural work, and for neighbours above, below or alongside. Compare quotes from party wall surveyors who handle shared floors, walls and freeholders.

In a block of flats the walls between homes are shared, and so can be the floors and ceilings. Whether the Party Wall etc. Act 1996 applies depends on how the building is arranged and who owns what. A floor between flats counts only where the flats are reached by separate staircases or entrances, which can be so in converted houses and maisonettes, and the work must be the kind the Act covers, such as cutting into the structure for a steel beam. Decorating, fitting a kitchen or replacing flooring usually do not count. Flats add a second layer: more than one owner may need notice, the freeholder or management company may need to give consent under the lease, and neighbours above and below share the noise and dust. A party wall surveyor can work through all of this with you.

How a professional can help

Working out whether the Act applies: Many flat renovations never touch the shared structure. A surveyor reads your plans, decides whether any work cuts into, removes or changes a shared wall, floor or ceiling, and tells you which notices follow.
Identifying every owner who needs notice: In a block there can be a freeholder, a management company and several leaseholders. Who counts as an owner depends on the leases, so the surveyor checks before notices are served.
Schedules of condition for several flats: Recording cracks, finishes and ceilings in the flats above, below and alongside, so any later complaint of damage can be judged against a clear record.
Noise, dust and working hours: Setting working hours, protection for shared stairs and lifts, and limits on noisy work such as breaking out, so neighbours living above and below can plan around it.
Lease permission alongside the Act: Explaining that the freeholder’s permission under your lease is separate from party wall rights, and helping you present the structural details that the freeholder’s own surveyor will want to see.
Acting for a neighbouring leaseholder: If a flat above or below has served notice on you, a surveyor can check the plans, explain your options and act for you, so your ceiling, walls and home are protected.

Is this right for you?

You are removing a load-bearing wall in a flat and the new steel will bear on or near a shared wall or floor.
You are converting a house into flats, or joining two flats, and the new layout cuts into shared structure.
You are a leaseholder who has received a notice from a neighbour above, below or next door.
Your freeholder or managing agent has asked for evidence that party wall matters are in hand.

How the project usually runs

Check the plans and the leases: The surveyor looks at the drawings and structural design to see which work touches shared structure, and checks who the owners are from the titles and leases you can share.
Notices to each owner: Notices go to every owner who needs one, in the correct form and with the right notice period, so work does not start before neighbours have had a chance to respond.
Record the surrounding flats: Where neighbours consent or surveyors are appointed, the surveyors inspect the flats around the work and record walls, ceilings and floors in a schedule of condition.
An award that suits the block: The award covers the work, protection of shared areas, working hours, deliveries, noise limits and how damage is made good, taking account of the other residents.
Work and final inspection: Once the work is done, the surveyors revisit the flats around yours, check ceilings, walls and shared stairs against the schedule and agree any repairs.

What affects the cost

How many neighbouring flats and owners are affected, including any freeholder or management company.
Whether each affected owner consents, or surveyors have to be appointed and an award agreed.
How many rooms and ceilings need recording in the schedule of condition.
The type of work, from one beam bearing on a shared wall to several walls removed across a flat.
Whether access through shared stairs, lifts and corridors needs special protection or timing.

Leases, freeholders and shared structure

The Party Wall etc. Act 1996 covers England and Wales. Rules for flats differ in Scotland and Northern Ireland, though party wall surveyors work across the UK.
Your lease may require the freeholder’s written permission for structural work. A party wall notice does not give it, so ask the freeholder or managing agent what they want to see.
Structural alterations in a flat normally need Building Regulations approval, or a building warrant in Scotland, and building control will want calculations, so a structural engineer should design the work before any wall is touched.
Internal work in a listed block of flats may need listed building consent, which is another separate approval.

Questions people ask

Does removing a wall inside my flat need party wall notices?

Only if the work involves a wall or floor that the Act treats as shared, such as steel bearing into a wall that separates your flat from the next. A partition wholly inside your own flat usually does not. A party wall surveyor can confirm from the drawings.

Do I need to tell the flat above or below?

If your work cuts into the ceiling structure, the floor between flats or a wall you share with them, notices may need to go to them, depending on how the building is arranged. Where it does not, it is still good practice to warn them about noise, and your lease or building rules may ask you to.

Is the freeholder an owner under the Act?

Often, yes. A freeholder and a long leaseholder can each count as an owner, so notices may need to go to both. Who must receive them depends on the leases, which your surveyor will check before anything is served.

Does converting a house into flats need party wall notices?

Often, for part of the work. Conversion commonly cuts into walls shared with neighbouring houses, for steel, new openings, flues or sound insulation, and those can need notice. A party wall surveyor can also tell whether floors between the new flats count as party structures, which depends on how each flat is entered.

Can the award control noise and working hours?

Yes. An award can set working hours, protection for shared stairs and corridors, and limits on noisy work such as breaking out, although it cannot remove all disturbance. Owners above and below can raise their concerns through their own surveyor.
