End-to-end Party Wall Act 1996 service for Sutton — Section 1, 3 and 6 notices, schedule of condition surveys, party wall award coordination. We handle the process so your Sutton build starts without neighbour disputes.
Three triggers, each with its own period: two months for work to a shared wall, one month for a new wall at the boundary, and one month for excavation within three or six metres of a neighbour’s foundations. Planning permission does not replace any of them.
| Section | Work it catches | Notice period |
|---|---|---|
| Section 1 | New wall at or astride the boundary | 1 month |
| Section 2 | Cutting into, raising or removing a shared wall | 2 months |
| Section 6(1) | Excavating within 3m, deeper than their foundations | 1 month |
| Section 6(2) | Excavating within 6m, inside a 45-degree line | 1 month |
| Section 10 | Neighbour dissents or does not reply in 14 days | surveyors appointed |
| Sutton householder decisions | 2,141 | 86.3% approved |
Sources: the Party Wall etc. Act 1996, sections 1, 2, 6 and 10, read at 1 September 2026; Sutton decision figures from MHCLG District Planning Application Statistics (PS1 and PS2), twelve quarters to March 2026. A neighbour who does not reply within fourteen days is deemed to have dissented, which is the commonest way a Sutton extension acquires a party wall award nobody budgeted for.
Party wall services in Sutton, a borough of 1930s semi-detached dominates; Edwardian terraces and villas in Sutton central; Victorian cottages in Carshalton; post-war in Hackbridge, are the full measured-survey-to-submission drawing set London Borough of Sutton needs in order to determine an application: existing and proposed plans, elevations and sections at 1:100 and 1:50, a location and site plan, and the supporting statements the case officer asks for.

End-to-end Party Wall Act 1996 service for Sutton — Section 1, 3 and 6 notices, schedule of condition surveys, party wall award coordination. We handle the process so your Sutton build starts without neighbour disputes.
Housing stock in Sutton: 1930s semi-detached dominates; Edwardian terraces and villas in Sutton central; Victorian cottages in Carshalton; post-war in Hackbridge.
Character: Outer south London suburban; generally permissive; Carshalton and Cheam conservation areas add heritage in pockets.
We check the project against the Act and tell you which section is engaged. Section 1 covers a new wall built on or at the line of junction. Section 2 gives the right to work on a party structure, and that work is notified under section 3. Section 6 covers excavation near an adjoining owner's foundations. Sources that swap the last two around are common, and since the section decides the notice period, getting it wrong costs weeks.
Notices drafted and served on every adjoining owner in the form the Act accepts, with both the statutory period and the reply window tracked: the adjoining owner has fourteen days to respond.
A schedule of condition, photographed and written up before anything starts. It is what stops a crack that was already there in March becoming your liability in September.
Technical drawings showing the work against the wall itself, against the foundations, and against whatever the neighbour has built on the other side of it. A surveyor has to see precisely what is intended, which is what the Act is after.
Where a neighbour dissents, we arrange the appointment. Either both owners agree on a single surveyor, or each appoints their own and the two of them settle an award between them.
We stay in it through the award itself: method statements, temporary works, access arrangements, all the way to a signed award and a start on site that nobody can stop.
Single planning or regs submission.
Planning + building regs + structural.
Listed, conservation, complex sites.

Every Sutton district on our books, what was built there and when, and which council decides an application coming from it. Fees quoted below are set by statute for England in 2026 and are payable to the council, not to us.
| Postcode | Area | Dominant stock | What it means for a party wall package |
|---|---|---|---|
| KT4 | Worcester Park | 1930s semi-detached | KT4 covers Worcester Park, which straddles the boundary with Kingston upon Thames, so the address rather than the district settles which council determines an application. |
| SM1 | Sutton | Edwardian terraces, 1930s semi-detached | SM1 is the town-centre district, entirely inside the borough and determined by Sutton Council against its own Local Plan policies. |
| SM2 | Sutton / Belmont | Georgian villas, 1930s semi-detached | SM2 covers southern Sutton and Belmont, wholly inside the borough. The conservation-area boundaries drawn across that district are the constraint most likely to alter a design there. |
| SM3 | Cheam / North Cheam | Georgian villas, 1930s semi-detached | SM3 takes in Cheam and North Cheam, both within the borough, so a Sutton case officer determines the application under the borough's Local Plan. |
| SM5 | Carshalton | Victorian terraces, Georgian villas | Carshalton lies entirely inside SM5 and inside the borough, so Sutton Council determines any planning application from it. Party wall notices are a separate matter: they are served on neighbours, not on the council. |
| SM6 | Wallington / Hackbridge | Edwardian villas, 1930s semi-detached | Wallington / Hackbridge is inside SM6. The party wall route is statutory without being municipal — it runs on the Act's own notice periods, which is why it is started before Sutton Council is approached rather than after. |
| SM7 | Banstead | Interwar semi-detached is the dominant type, 30.6% of Sutton homes dating from the 1930s, with Edwardian terraces near the town centre, Victorian cottages in Carshalton and post-war stock at Hackbridge | Party wall matters in Banstead involve no council whatever, and the council behind any related application is not Sutton. The Party Wall etc. Act 1996 runs between owners and their surveyors wherever the house stands. Where SM7 work does need permission or building control, Reigate and Banstead Borough Council in Surrey deals with it, because Banstead falls outside Greater London. |
Roof pitch, wall build-up and how deep the plot runs all change from street to street in Sutton, and all three affect what is buildable and what the neighbour on the boundary is being asked to agree to.
Conservation areas covering Sutton: Sutton Council runs 17, and Carshalton Village, Beddington Park, Cheam Village are the ones Sutton owners meet most. A party wall package inside a Sutton conservation area loses permitted development, so the Sutton submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Sutton Central a party wall package is judged on the street elevation first.
Article 4 and your Sutton party wall package: Sutton Council has made no borough-wide direction, so permitted development for a party wall package in Sutton generally survives outside Sutton conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a KT4 owner records that a party wall package was lawful.
Sutton housing stock: 1930s semi-detached dominates; Edwardian terraces and villas in Sutton central; Victorian cottages in Carshalton; post-war in Hackbridge. Outer south London suburban; generally permissive; Carshalton and Cheam conservation areas add heritage in pockets. Read that before choosing a party wall package route in Sutton — construction, not postcode, sets what is achievable. Sutton Council charges £548 for a householder application and has 8 weeks to determine it.

Direct answers to what Sutton homeowners ask about party wall work. One piece of context worth carrying into it: this council is fast. Of 1,994 householder decisions recorded across its speed bands over the three years to March 2026, 1,967 landed inside 8 weeks and only 8 in total took longer than 13 weeks. Sutton also agreed an extension of time on 13.5% of its decided applications, against 34.5% across the 33 boroughs, so the speed is genuine rather than bought with paperwork.

Start a free quote →Notices are needed for work that puts a wall on or across the boundary, for cutting into a party wall or party structure, and for excavation close to a neighbour's foundations — within 3m at the shallower test, within 6m where the dig drops below a line taken at 45 degrees from their footings. Most Sutton loft conversions, extensions and basement digs engage at least one of the three.
If the neighbour consents, that is the end of the spending. A dissent brings in surveyors, whose fees are extra and counted per neighbour rather than per project, so a mid-terrace with owners on both sides can cost twice what an end-of-terrace does. The notices themselves are included in our Complete packages.
Count the statutory periods before anything else. It is one month for a line of junction notice under section 1, two months for a party structure notice under section 3, one month for an adjacent excavation notice under section 6. Consent can come back sooner, and the adjoining owner has fourteen days to respond, but the notice period itself is fixed by the Act rather than by agreement. Where surveyors are appointed, allow 6-8 weeks for the award. We serve early so all of it runs beside the planning application instead of after it.
No. Work that is notifiable and begins before valid notices, or before an award where one is required, is unlawful under the Party Wall etc. Act. An injunction can stop the site, a damages claim can follow, and the protections the legislation would otherwise have given you are gone. Serving early costs nothing and removes all of it.
Silence does not mean agreement. An adjoining owner who fails to reply is treated by the Act as having dissented, and the surveyor process begins there: you appoint one, the neighbour may appoint theirs at your cost, or the two of you settle on a single agreed surveyor. We keep it moving, because the adjoining owner has fourteen days to respond and nothing pauses while somebody thinks it over.
