Free site survey
A free cabling survey in London and the South East, before any quote.
Our free site survey is a cabling survey of your building, carried out at your premises by one of our own engineers, at no cost to you and with no obligation. We look at cable routes, comms rooms and the infrastructure you already have, then send a full written quotation with clear, itemised costs. Not a sales visit.
One survey covers structured cabling, fibre, CCTV, Wi-Fi and access control together. We cover London, Kent, Surrey and the wider South East from our offices in the City of London and Orpington.
Call 0333 900 0101 or email sales@network-data-cabling.co.uk to arrange a free site survey, or fill in the form and we will be in touch within one business day.
What happens next
- We confirm a dateSurveys are typically arranged within a few days of your enquiry.

Why we survey first
Why a free site survey makes all the difference
Most cabling and network projects look straightforward until someone actually walks the building. Thick walls, unknown existing infrastructure, legacy coax and systems that depend on each other across several floors: none of that shows up in a phone call or an email.
It only becomes clear when an experienced engineer is standing in your building, looking at what you actually have. That is why every ACCL project begins with a no-obligation free site survey: a working assessment by one of our own engineers, at your premises, at no cost to you.
It is also how we protect you from the thing that frustrates clients most about our industry: quotes that bear no resemblance to the final invoice.
The biggest cost in any structured data cabling or network infrastructure project is labour, more than materials. Labour cannot be estimated accurately without seeing your building. The free site survey gives us that information, and it gives you an accurate quote.
Why we always start with a free site survey
Every building is different. A modern open-plan office, a Victorian school with metre-thick walls, a healthcare facility with strict access controls, a multi-floor commercial fit-out with no existing documentation: each one has its own challenges and needs its own solution. The survey exists for three reasons.
- To understand your building before we price it
We look at cable routes, wall and ceiling construction, existing infrastructure, comms room locations and access constraints. Without this information, any quote is little more than a guess.
- To understand your full requirements
Many clients arrive with one project in mind and discover during the walkthrough that data cabling is the foundation for several others: CCTV, Wi-Fi, access control, IP intercoms. Scoping everything together at survey stage means a single coordinated plan, with no separate contractors working at cross purposes.
- To prepare your risk assessment and method statement
These are a professional and legal requirement for any contractor working in a commercial, educational, healthcare or public sector building, and they cannot be prepared accurately without a proper survey.
On the day
What happens during the free site survey
Here is exactly what your free site survey covers from the moment we arrive. Most surveys take between 30 minutes and an hour.
We walk the building with you
The survey starts with a conversation about what you are trying to achieve and what is not working today. Once we understand the brief, we walk the building together and assess everything that affects how the job gets done.
We assess your existing infrastructure
We check what cabling and equipment is already in place and what condition it is in. Whether you have legacy coax, ageing Cat5 or nothing documented at all, we give you an honest view of what can be reused and what needs replacing.
We identify cable routes and access
We map out how cables will run through your building, looking at ceiling voids, trunking, wall construction and comms room locations. Knowing the route before we quote means no surprises when the work begins.
We inspect your comms room
We inspect your server room, data cabinets and patch panels to see what is there, what condition it is in, and whether it needs upgrading or tidying as part of the wider project. A clean, well-organised comms room is the foundation of a reliable network.
We identify the full scope
Many clients discover during the walkthrough that data cabling underpins several other projects. We scope everything together, so you have one coordinated plan covering CCTV, Wi-Fi, access control and cabling in a single visit.
We consider your timeline and phasing
We discuss your programme, whether that is a summer shutdown, a phased fit-out or a live environment that needs careful scheduling. If budget or timing means the work is delivered in stages, we plan for that from the outset.
We prepare your documentation
Before any installation work begins, your site needs a risk assessment and method statement. The survey gives us everything we need to prepare these accurately, covering your people, your building and how the work will be carried out safely.
We produce your written quote
After the survey you receive a full written quotation with clear, itemised costs and no provisional sums. Because we have seen your building, the quote reflects the real job: no ballpark figures and no unexpected additions when the engineers arrive.
One visit
What the free site survey covers
A single free site survey can scope all of the following in one visit. If you have several projects, one survey covers all of them: one visit, one point of contact and one coordinated plan. Whatever you call it (a cabling survey, a network infrastructure survey or a pre-installation site survey), it is the same visit: one of our engineers checks the building before anything is priced or installed.
Structured cabling site survey
Structured data cabling including Cat6, Cat6a and fibre for new installations, upgrades or office moves: network points, patch panels, server cabinets and comms room infrastructure.
This is what most people mean by a data cabling survey or a commercial cabling survey: how many outlets you need, where the cables will run and what the comms room needs.
Survey of your existing cabling
If you mainly want to know what you already have, the survey tells you: what is installed, what condition it is in, and what can be reused to reduce cost.
For a fuller documented check of a live network, see network auditing.
Fibre between comms rooms and buildings
Fibre backbone routes between comms rooms, floors or buildings: where the fibre will run, how it enters each comms room, and how each link will be tested and certified at handover.
CCTV site survey
CCTV camera positions, existing coax condition, and the options for upgrading to a full IP system.
Wi-Fi and coverage planning
Wi-Fi access point placement and coverage planning, including backhaul cabling and PoE switching requirements.
For a detailed wireless coverage survey, see Wi-Fi site surveys.
Access control and door entry
Access control and security barrier infrastructure. IP intercom and entry phone systems, including cabling for new handsets or door units.
Comms rooms and IT refresh
IT refresh requirements, including cable management, cabinet tidying and server room organisation.
Who is this for
Our free site survey is open to any business, organisation or institution planning infrastructure work across London, Kent, Surrey and the surrounding areas. You do not need a fully formed brief. If you know something needs doing but are not sure where to start, the free site survey is the right first step.
We regularly work with IT managers and engineers who have a technical brief but need an experienced installer to check it on site. We work with facilities managers responsible for buildings with complex or completely unknown existing infrastructure.
We work with school business managers and bursars planning summer upgrade programmes, and with property managers coordinating works across single or multiple sites. We work with healthcare facilities where continuity of service is critical, and with commercial fit-out teams who need infrastructure signed off before a new tenant moves in.
If your building needs a network, we can survey it.

Risk assessment and method statement
The survey gives us what we need for your RAMS
Risk assessment: understanding your people and your building
Before any installation work begins, we produce a full risk assessment for your site. This is a formal document that identifies every potential hazard linked to the proposed works, looking at two areas: the people in your building, and the building itself.
On the people side, we consider who is present during working hours and how the installation affects them. In a live office that means working around staff with minimal disruption to daily work. In a school it means knowing where children and teaching staff are at all times, so installation work never puts their safety or routine at risk. In a healthcare setting it means accounting for patients, clinical staff, and areas where noise, dust or a power interruption could have serious consequences.
On the building side, we assess structural considerations, the condition of existing infrastructure, ceiling void access, asbestos risk in older buildings, fire compartment integrity, and any access restrictions that affect how and when work can safely take place. Older buildings in particular, including period commercial properties, converted schools and listed structures, need careful assessment before any cable routing or fixings are agreed.
The risk assessment is the document that protects your staff, your visitors, your building and our engineers. Nothing goes on site without it.
Method statement: how we overcome the risk
Where the risk assessment identifies hazards, the method statement sets out exactly how we will manage them. It is a step-by-step account of how the installation will be carried out safely: the sequence of work, the techniques and equipment used, the protective measures in place, and who is responsible for what.
For a straightforward office data cabling project this might cover working hours, dust protection for active workstations, cable containment methods, and how each run is tested and certified before handover. For a more complex project in a school, hospital or occupied building it covers segregation of work areas, communication with building management, emergency procedures, and specific controls for working at height or within fire-rated voids.
The method statement also details the qualifications and accreditations of the engineers carrying out the work: our SafeContractor, CHAS and SSAIB certifications, our ISO 9001, ISO 14001 and ISO 45001 management standards, and our £10m liability cover. Many sites, particularly schools, NHS premises and local authority buildings, need this documentation before they will let any contractor in. We produce it as standard.
Together, the risk assessment and method statement mean that by the time our engineers arrive, every foreseeable risk has been identified, every control measure is in place, and everyone knows what is happening and when. It all starts with a free site survey.
When the survey includes Wi-Fi
Advanced security measures for commercial Wi-Fi installations
Commercial Wi-Fi security should be designed into the installation from the start, not added afterwards. When your survey includes Wi-Fi, we plan for it then. ACCL configures business-grade Wi-Fi networks to help protect company data, separate users and devices, and reduce the risk of unauthorised access. Security measures can include:
- WPA3 encryption where supportedHelps protect wireless traffic as it moves across the network.
- Secure guest Wi-FiSeparates visitors from internal business systems and helps protect your corporate network.
- Staff and visitor network separationKeeps managed users, guest users and unmanaged devices on the right network segments.
- VLAN segmentationHelps separate traffic across departments, devices or user groups, supported by the wider network and switching design.
- Firewall alignmentMakes sure wireless access rules match your existing security policies.
- Secure management accessReduces the risk of unauthorised changes to access points, controllers or cloud-managed platforms.
- Firmware update guidanceHelps reduce exposure to known vulnerabilities after installation.
- Documented configuration notesGives your IT team a clear record of SSIDs, segmentation, access policies and future changes to consider.
For larger or more sensitive environments, additional controls may include 802.1X authentication, role-based access, multi-factor authentication processes and monitoring support to help identify unusual network activity.
A professional Wi-Fi installation gives your IT team a secure, manageable wireless network with clear documentation, instead of a collection of access points, shared passwords and unknown configuration risks.
Cost and next steps
What it costs and what happens after the free site survey
Nothing. The free site survey carries no charge and no obligation whatsoever.
We offer a free site survey because accurate quotes need accurate information, and accurate information needs someone to see your building. It is how we protect you from unexpected costs and how we protect our own reputation for delivering what we promise. We have been doing this for over 28 years and our approach has not changed.
Once the assessment is complete you receive a full written quotation with clear, itemised costs: no ballpark figures, no provisional sums and no surprises on the day. Alongside the quote we provide the risk assessment and method statement for the proposed works, and honest recommendations, including where existing infrastructure can be reused to reduce cost.
You are under no obligation to go ahead. If you do, a dedicated project manager becomes your single point of contact from that moment through to completion and handover. The same engineer who surveyed your building briefs the installation team, so nothing gets lost between the assessment and the work itself.
Our installations are backed by a 25-year warranty and £10m liability cover. We are SafeContractor approved, SSAIB certified and CHAS accredited. Every engineer we send to your building is directly employed, fully trained, and experienced in working in occupied buildings, including live offices, schools, hospitals and hospitality venues.

“One of very few suppliers that we never have to question their proposal on detail or price, everything is clear, transparent and fair. Projects are always completed on time and there are never any costly surprises which we had previously experienced from other suppliers. They all have a vast knowledge on anything fibre optic cabling, copper cabling or Wi-Fi. ACCL is now the only data cabling company in our phone book.”
“Very glad we went with ACCL to sort our office cabling. The entire process was very smooth, the quotation was clear and simple on exactly what work needed to be done. On the day the team got started right away and followed all our requirements.”
“Thank you to Wayne and the team for the excellent recabling and patching job at Wisemusic. Both Wayne and David worked with myself and the team to schedule the work around the business activities to cause the least disruption and downtime. Nothing was too much trouble for them. I will certainly use this company again and am happy to recommend them.”
“As the client I can only say thanks and its an amazing piece of work by all involved. Believe me that the work to coordinate this work around other issues was challenging but Wayne and ACCL were great.”
“We would like to take this opportunity to thank, You, Wayne and the team for such an excellent and professional implementation. The organisation was fantastic and the way you worked within the building was great, the business users did not even know what was going on in the building. We would definitely not hesitate to use you guys again.”

Before you book
Free site survey questions
Is the site survey really free?
Yes, completely. There is no charge for the survey and no obligation to proceed afterwards. The only time a charge would apply is if a project required significant travel outside our normal coverage area, and we would always tell you that upfront.
How long does a site survey take?
It depends on the size and complexity of your building, but most surveys take between 30 minutes and an hour.
How quickly can you arrange a free site survey?
In most cases we can arrange a free site survey within a few days of your initial enquiry. If you have a specific deadline, tell us when you call and we will work to your timeline.
Will the survey disrupt my business or building?
No. The survey is a walkthrough assessment, not an installation. There is no drilling, no cable pulling and no disruption to your network or your staff.
What should I have ready before the survey?
As much or as little as you have. Floor plans are useful if available, and a rough idea of how many network points, cameras or Wi-Fi access points you need is helpful but not essential.
Do you cover areas outside London?
Yes. We cover London, Kent, Surrey and the wider South East from our offices in the City of London and Orpington.
What do I actually receive after the free site survey?
A full written quotation with clear, itemised costs, a risk assessment and method statement prepared in line with Health and Safety Executive guidelines, and honest recommendations including where existing infrastructure can be reused to save cost.
Do I need to know exactly what I want before I call?
Not at all. Whether you have a detailed technical brief or simply a building that is not working as well as it should, our engineers will assess what you have and give you an honest view of the options.
