Party Wall Surveyor Chelsea | Fixed Fees From £165

Grey & Associates are party wall surveyors in Chelsea, covering SW3, SW10 World's End and West Brompton, Chelsea Embankment and Cheyne Walk, Sloane Square and the King's Road. We act for owners building and for owners who have received a notice. Fixed fees start at £165 + VAT per adjoining property.

Key takeaway

Chelsea cases turn on three things. The plots are narrow and the terraces are built hard against their boundaries, so almost any rear or basement project puts new foundations within three metres of a neighbour — and often of two. The river is close enough on the southern streets to make ground water a real factor in basement work, which pushes the Schedule of Condition to the centre of the case. And much of the housing is leasehold with estate ownership behind it, so the adjoining owner is frequently a freeholder or an estate rather than the person living next door.

If you have received a notice and you own a flat or a leasehold house, the position is usually stronger than people expect: in a dispute the Building Owner pays the reasonable fees of both sides' surveyors.

What makes Chelsea different

Narrow plots, long party walls

Chelsea was built as narrow-fronted terraces with almost no space between the house and the boundary. There is rarely a side return of any size, which means extension and basement work goes backwards and downwards rather than sideways — straight along a party wall that runs the full depth of the property. New foundations, lightwells, drainage runs and any below-ground structure therefore sit within the three-metre band of the neighbouring house as a matter of course, and section 6 follows. Where the scheme also cuts into or underpins the shared wall, section 2 adds a two-month notice to the same project.

The river streets

Along Chelsea Embankment, Cheyne Walk and the streets running down to it, ground water is a material factor rather than a theoretical one. Basement schemes here have to manage it, and the arrangements for dealing with water often involve consents from bodies outside the party wall process. What matters for the Act is that the neighbouring property's existing damp, drainage and cellar condition is recorded properly and early: once the excavation begins, the opportunity to take that record has gone, and a subsequent ingress claim becomes an argument about the past rather than a comparison of evidence.

Mews, estate ownership and leasehold

Chelsea has a large number of mews properties, and they produce the most commonly misread party wall questions in the area. A wall between two mews houses may be a party wall, a party fence wall or wholly within one title, and which category it falls into decides the notice position. We check the title plan and the construction before advising. Behind much of the housing sits estate and institutional freehold, so the adjoining owner is often the estate rather than the occupant — and on the larger estates there are management and licence requirements running alongside the statutory process.

Basements and underpinning under Chelsea houses

Basement excavation is the most demanding work we do in Chelsea, and it is where our experience is deepest. Four issues come up on almost every scheme.

Depth against shallow footings. Chelsea's Victorian and Edwardian houses typically sit on stepped brick footings close to ground level. A basement that gains headroom passes well beneath them, which brings section 6 into play — and with it the section 7 duty to compensate the neighbour for loss or damage caused by the work.
Water. On the southern streets, dewatering, tanking and the neighbour's own below-ground drainage all form part of the works. The Schedule of Condition has to record the neighbour's cellar, sump, tanking and existing damp before work starts, because that is the only thing that separates their pre-existing condition from anything your excavation causes.
Two-storey schemes and temporary works. Double basements are commonplace. They need propping or piling to support the neighbouring structure, and often the underpinning of the neighbour's foundations before the dig reaches them. Those operations are themselves notifiable and have to be described accurately in the award so the contractor can build to it.
Access. With no side space, a basement site in Chelsea operates from the front or through the house, and scaffold, skips and deliveries end up on or over neighbouring land. The party wall award governs the notifiable work; it does not give you the neighbour's land. Getting access agreed in writing at the start avoids weeks of delay later.

Basement and underpinning work is quoted separately from our fixed fees, after we have seen the structural drawings and the method statement. Our basement and underpinning party wall page sets out how we run those cases.

Fees for party wall work in Chelsea

Fixed and published: £165 + VAT per adjoining property to serve notice, £620 + VAT per Schedule of Condition, and £350 + VAT per adjoining property for an award acting for the Building Owner. A one-neighbour dispute — notices, one Schedule of Condition and the award — is £1,135 + VAT. All prices exclude VAT, charged at 20%: the £1,135 figure carries £227 of VAT, so £1,362 including VAT.

Basement and underpinning works are priced differently. Deeper excavation, dewatering, more engineering input and far more extensive schedules put them outside the fixed figures above. We review your plans and the proposed works first, then present a formal written quote before anything is agreed or any notice is served. Dispute and non-compliance work is charged separately at £185 per hour plus VAT. Nothing in this section is an offer.

Chelsea party wall questions

Does excavating a basement near Chelsea Embankment or Cheyne Walk change the party wall position?

The legal tests stay the same — section 6 applies once the excavation is within three metres of a neighbouring structure and deeper than its foundations, or within six metres where the dig would cut a 45-degree line from the bottom of those foundations. What changes near the river is the consequence of getting the evidence wrong. Ground water is a live issue on riverside sites, so dewatering and any discharge arrangements are part of the works, and the Schedule of Condition has to record the neighbouring property's existing damp, drainage and cellar condition in detail before the dig begins. Water ingress and movement are the two claims that follow a neighbouring excavation most often, and both are decided by that record.

Is the wall between my Chelsea mews house and my neighbour's a party wall?

Not automatically, and the answer changes what you are allowed to do. A wall that forms part of both buildings is a party wall and the full machinery of the Act applies. A wall that is not part of any building, stands on land belonging to different owners and separates those lands is a party fence wall — a distinct category under the Act, and section 2(2) gives rights to underpin, thicken or raise it. If the wall is wholly within one title, it may not be a party structure at all. We check the title plan and the construction before serving or advising on works, because assuming the wrong category is a common and expensive mistake in mews properties.

The freehold of my neighbour's Chelsea house is held by an estate. Who is served?

The interest holding the structure, which is usually the freeholder or the estate — not the tenant or the managing agent's occupant. In Chelsea a substantial amount of housing is held on long leases, with the freehold in estate ownership, and the person living next door may be a tenant with no interest in the party wall at all. We establish who holds the relevant title before serving. If the building is sub-divided, there may be more than one adjoining owner, and each needs their own notice.

What does a party wall surveyor cost in Chelsea?

Fixed fees: £165 per adjoining property to serve notice, £620 per Schedule of Condition, and £350 per adjoining property for an award acting for the Building Owner. A one-neighbour dispute — notices, one Schedule of Condition and the award — is £1,135 all-in. All figures exclude VAT at 20%. Basement and underpinning works are priced differently, and a formal quote is presented after we have reviewed the plans and the proposed works.
