Party Wall Surveyor in Epsom
KT17, KT18 and KT19 — Surrey-border semis and detached houses in Epsom, Ewell and Stoneleigh, just beyond the London boundary
Grey & Associates are party wall surveyors in Epsom, covering KT17, KT18 and KT19, Epsom town, Ewell, Stoneleigh and the Worcester Park and Ashtead borders. The town sits just outside Greater London but inside our M25 service area. Fixed fees start at £165 + VAT per adjoining property.
Epsom is a Surrey-border market rather than a dense London borough. The housing is mostly 1920s to 1970s semi-detached and detached, with larger plots towards the Downs and Stoneleigh. The common projects are lofts, rear and side extensions, and garden walls, and most cases involve one neighbour rather than several.
If a notice has arrived and you own a flat in a converted house or block, the position is usually stronger than people assume: in a dispute the Building Owner pays the reasonable fees of both sides' surveyors.
What Epsom cases turn on
Semis and detached houses around Epsom and Ewell
The standard Epsom case is a loft conversion or rear extension on a semi-detached or detached house. On a semi, the party wall runs the full depth of the building and into the roof, so the work can be notifiable even if the extension sits entirely within the owner's plot. On a detached house the issue is more often excavation close to the neighbour's structure or a boundary wall.
The housing is generally younger than inner London stock, but shallow footings and later extensions still create section 6 questions.
Stoneleigh, the Downs and larger plots
Towards Stoneleigh and the Downs the plots are larger and the houses more often detached. Projects can include two-storey additions, basement schemes, outbuildings and new build at the end of a garden. A new wall on the line of junction is section 1; excavation below the neighbour's foundations is section 6.
On larger plots access is easier, but the structural and drainage review is more important. A basement or lower-ground scheme is priced separately after we see the plans.
Garden walls and the Surrey border
Epsom has a lot of boundary-wall work. Rebuilding a garden wall in brick, raising it or replacing a fence with a wall can engage section 1 or the party fence wall provisions. The deeds and the physical position of the wall decide which applies.
Because Epsom is outside Greater London, owners sometimes assume the Act does not apply. It does: the Party Wall etc. Act 1996 covers England and Wales, and the same notice and award process applies.
What catches people out in Epsom
- The Act applies in Surrey too. Epsom is outside Greater London but inside England, so the Party Wall etc. Act 1996 applies in the ordinary way.
- Check the boundary wall before replacing it. A new wall on the line of junction is section 1; an existing party fence wall is section 2. The deeds and the physical position decide.
- Do not assume a detached house is outside the Act. Excavation close to the neighbour's structure can still be section 6 work.
- Record the existing garden and drainage. On larger plots, the schedule should cover the boundary, outbuildings and drainage as well as the house.
For the underlying law, the Party Wall Act explained sets out the framework. Our party wall notice guide, schedule of condition guide and party wall award guide cover the three documents every case runs through.
Fees for party wall work in Epsom
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 at 20%.
Basement and underpinning works are priced differently. Deeper excavation, more engineering input and 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.

Epsom party wall questions
Does the Party Wall Act apply in Epsom?
Yes. The Party Wall etc. Act 1996 covers England and Wales, so it applies in Epsom and Ewell in the same way as in London. The notice periods and the award process are the same.
Do I need a party wall notice for a loft conversion in Epsom?
If the work touches the party wall between two semis, yes. Cutting in a steel, raising the wall, forming a gable on the boundary or altering a shared chimney breast is section 2 work with a two-month notice period. A detached-house loft may fall outside the Act if no shared structure is affected.
My neighbour is building a new wall on the boundary. What notice should they serve?
A new wall on the line of junction is section 1 work, and the notice period is one month. If the wall is to be built astride the boundary, the neighbour may also need your written agreement to the position. The Act does not oblige you to pay half unless you agree to do so.
What does a party wall surveyor cost in Epsom?
£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 is £1,135 + VAT. Basement and underpinning work is quoted separately.
