Party Wall Matters
Site Sage are specialist party wall surveyors based in Harlow, Essex. We cover all of London and the surrounding counties.
If you are planning work that comes under the Party Wall etc. Act 1996, or your neighbour is, we can help.
For the building owner
You must serve notice before you:
- build a new wall on or near the boundary
- repair, alter, raise, cut into or underpin a party wall
- dig foundations within 3 or 6 metres of a neighbour's building
For the adjoining owner
If a neighbour has served notice on you, or has started work without one, we will:
- explain your options and reply to the notice for you
- act as your surveyor or as the agreed surveyor
- record the condition of your property before work starts
- check the plans and agree the award with the other surveyor
- deal with any damage and compensation
Why Site Sage
Dennis Brett is a Fellow of the Faculty of Party Wall Surveyors with over 40 years in construction. He handles every instruction himself.
Fees
Minimum fee £700 for a new instruction. If you are the adjoining owner, your neighbour normally pays your surveyor's fees.
Access Agreements

Site Sage prepare access agreements so building owners can carry out work that needs a neighbour's land.
When you need one
You may need to put scaffolding on or over a neighbour's land, swing a crane over their roof, put up hoarding, take materials across their site, or dig trial pits or ground anchors on their side. None of this can be done as of right. Without a signed agreement, work can be stopped by injunction at short notice.
What the agreement covers
- what is allowed and for how long
- protection and insurance
- what happens if there is damage
- what the neighbour receives in return
What we do
We act for building owners who need access and for neighbours who have been asked to give it. We agree the scope, prepare or check the licence, record the condition of the neighbour's property before work starts, and check it is handed back in the same state.
Where the work comes under the Party Wall etc. Act 1996, we deal with access as part of the party wall process. For repairs and maintenance, the Access to Neighbouring Land Act 1992 may apply.
Fees
Minimum fee £700 for a new instruction. Hourly rate £185. If you are the neighbour, the building owner normally pays your fees.

PRINCIPAL DESIGNER SERVICE
Site Sage have worked on CDM since 2007, first as CDM Coordinator and now as Principal Designer under the Construction (Design and Management) Regulations 2015. Projects have ranged from £30,000 to £2 million, for developers, architects, contractors and property managers.
Principal Designer
We plan, manage and coordinate health and safety at the design stage, so risks are dealt with before anyone is on site. We keep the paperwork to what the law needs, and we write in plain English.
- Pre Construction Information
- design risk reviews with the project team
- the Health and Safety File at handover
Construction Phase Plans
Work cannot legally start without one. We prepare the plan setting out the site rules and safety arrangements, ready before you start.
Construction Traffic Management Plans
We prepare CTMPs covering site set up, hoarding and scaffold, vehicle routes, deliveries, waste and the programme. They follow the local authority's standards and, where needed, Transport for London's CLOCS scheme.
Site safety visits and advice
We inspect the site and the site files, then report whether things are acceptable or need action. We also give general health and safety advice.
Fees
See our Fees page for Principal Designer and health and safety fees, or ask us for a quote.
Building Surveys
Site Sage carry out independent building surveys on homes and commercial property across Harlow, Essex, London and the surrounding counties.
What a building survey is
A building survey, once called a structural survey, is the most detailed report you can get before you buy. It is separate from your lender's valuation and is written for you, not the bank.
When you need one
- older, listed or unusual buildings
- a property you plan to extend, convert or renovate
- anywhere you are not sure of the condition
- commercial premises
What you get
A clear report on how the building is built, what condition it is in, what needs doing and how urgent it is. Major and minor defects are covered, with photos. It goes further than an RICS Home Survey Level 2.
Commercial leases
We also prepare Schedules of Condition before you take a lease, and Schedules of Dilapidations when a lease ends or is renewed.
Fees
Minimum fee £700 for a new instruction. Use the survey calculator on our Fees page for a guide price.

Each one sets out the instructions, the inspection, the findings with photographs, the opinion and the reasoning behind it, with appendices and a signed statement of truth.
Timescales
Inspection within 7 days of instruction. Report within 14 days of inspection, sooner where possible. Most instructions are completed within three weeks, against a typical industry timescale of six to eight weeks.
