There is no single price for a commercial WiFi site survey in the UK. The cost is set by the survey type (predictive, passive or active), the floor area, the building construction, the number of sites and the depth of the report. A predictive survey is a desk-based exercise and sits at the lower end. An on-site survey needs engineers walking the building with measurement equipment and costs more because of the time and travel involved.
This guide explains how suppliers build a quote, so you can compare proposals on the same basis, brief them properly and avoid paying for work you do not need. Re-Solution does not publish fixed survey prices, because a fair figure depends on the building. We explain below what we need to know to give an accurate one.
TL;DR
- Survey cost is driven by scope, not by a standard rate card: area, building type, survey method, number of sites and reporting depth.
- Predictive surveys are modelled from floor plans and are the quicker, lower-cost option. On-site surveys take measurements in the live building and take longer.
- Dense, high-ceilinged or metal-heavy spaces such as warehouses and manufacturing floors need more measurement time than open-plan offices.
- A good report names access point quantities and positions, expected signal quality, interference sources and cabling and power needs.
- Ask every supplier to quote against the same written brief, so the figures can be compared.

What a WiFi site survey is
A wireless survey exists to produce a document. According to Jisc, the end goal is to set out how many wireless access points are needed and where they should go, along with expected signal strengths or quality, likely interference and infrastructure requirements such as power, switches and cabling.
That definition is useful when you read a quote. You are not buying a walk around the building. You are buying a design basis that your installer, or your managed service provider, can build from with confidence. If you want the business case in more detail, our page on why invest in a wireless site survey covers it.
The three survey types and how they affect price
The survey method is the largest single driver of cost, because it determines how many engineer hours are spent on site.
| Survey type | What it involves | Typical use | Cost position |
|---|---|---|---|
| Predictive | Software models the RF environment from floor plans and building data | New builds, early budgeting, design before installation | Lowest, no site time |
| Passive (on-site) | Engineer walks the site with a listen-only analyser and records signal and interference | Pre-deployment design, rogue device checks, finding RF trouble zones | Mid, depends on area |
| Active (on-site) | Test client connects to the network and measures live performance | Post-installation validation, troubleshooting, performance problems | Mid to high, needs a live network |
These descriptions follow Cisco’s site survey guidelines. Passive surveys use listen-only mode and help identify rogue devices and RF trouble zones. Active surveys associate the client to access points and are commonly used for new WLAN deployments because they give the most design detail. Predictive surveys use software and coverage-area information to place access points using RF algorithms, typically without field measurements.
Jisc frames the same split in terms of when each is used: active surveys to troubleshoot post-deployment performance and measure throughput, packet loss, round trip time and signal levels; passive surveys in pre-development stages to choose access point locations; and predictive or virtual surveys to simulate the RF environment from imported floor plans.
Pricing follows the effort. A predictive survey costs less because no engineer travels or spends days on site. An on-site survey prices in travel, access arrangements, equipment and the time to cover every floor, and suppliers often quote it per day or per area band.
What drives the quote
When a supplier asks you questions before pricing, these are the reasons.
Floor area and number of floors
More area means more measurement points and more hours. Multi-storey buildings also need checking for signal bleeding between floors, which adds analysis time.
Building construction
Thick masonry, steel framing, fire-rated doors, lift shafts and metallised glazing all attenuate signal. Older and listed buildings can be difficult for this reason, and they may also restrict where equipment can be mounted. Surveyors need more test positions to find a workable design.
Environment and ceiling height
Open-plan offices are the simplest. Warehouses bring high racking, stock that changes through the year and tall mounting heights. Manufacturing floors add machinery and electrical noise. Our guide on what to brief your supplier for warehouse wireless sets out what logistics managers should specify.
Device and application requirements
The survey must be designed against a target, for example voice handsets, handheld scanners, high-density lecture theatres or guest streaming. A higher capacity target means more access points and more design work. Many UK enterprise teams are also planning for newer standards, and our note on Wi-Fi 7 readiness explains why a design for today’s clients may need more access points than a previous generation.
Number of sites
Multi-site estates such as school trusts, hotel groups and logistics networks usually benefit from a consistent method across sites. Travel and mobilisation are shared, and the report format is reused, which tends to lower the per-site effort compared with commissioning each site separately.
Access and working hours
A hotel, a school or a 24-hour distribution centre cannot hand over empty space for a day. Out-of-hours work, escorted access and phased visits all extend the engagement and affect cost.
Report depth and follow-up
A short summary with a recommended access point count is cheaper than a full design pack with heatmaps, bill of materials, cabling schedule and a post-install validation survey. Decide what you need before you ask for prices.
What should be in the report
For the money, you should receive a document your team can act on. At minimum, expect:
- the number and location of access points, marked on your floor plans;
- coverage and signal quality heatmaps against the stated design target;
- identified sources of interference, including neighbouring networks and non-WiFi sources;
- cabling routes, switch port counts and power requirements, consistent with the infrastructure points Jisc lists;
- mounting recommendations and any constraints found;
- the assumptions the design rests on, such as client types and capacity.
If a quote does not say what the deliverables are, ask. A cheaper quote that omits cabling or power details can cost more later in installation rework. Our hotel WiFi design guide shows how missed cabling decisions turn into rework in a live building.
When a predictive survey is enough
A predictive survey is a sound choice when the building is still at design stage, when you need a budget figure for a business case, or when the layout is simple and the construction is well documented. Accurate floor plans and known materials are the inputs that matter. Our page on predictive Wi-Fi surveys for IT managers explains how far a model can be trusted and where the margin for error lies.
Typical cases include:
- new-build offices, residential blocks and student accommodation, where the structure is known from drawings;
- early estimating for a refurbishment, before the budget is approved;
- repeatable layouts across many sites, such as similar retail or hotel floors.
See our guidance on when to order a survey for UK student accommodation Wi-Fi for a worked sector example.
When you need an on-site survey
Choose an on-site survey when the real environment will not match the drawings, or when the cost of getting it wrong is high.
- Existing WiFi that performs badly. An active or passive survey locates the cause, whether it is interference, poor placement or capacity.
- Challenging construction. Heavy walls, metal and glass change results enough that modelling alone carries risk.
- High-density or business-critical use. Lecture halls, conference areas, voice and handheld scanning need measured evidence.
- Post-installation validation. An active survey after installation confirms the design delivers what was specified.
Many projects combine the two: predictive for design and budgeting, then a targeted on-site check before or after installation. This usually gives better value than a full on-site survey of every space.
Can you survey it yourself?
For smaller, straightforward sites, some organisations use survey software themselves. Vendors of such tools say that for many offices, warehouses, schools and clinics this is possible with a professional wireless analyser: import the map, walk the site, review the heatmaps and decide where to place access points. The result depends on the equipment, on the skill of whoever interprets the data, and on the time your team can spare. For multi-floor, high-density or compliance-sensitive sites, a specialist survey backed by experienced Cisco-certified consultants gives you a design you can hold a supplier to.
How to get quotes you can compare
Suppliers can only price what they understand. A short brief removes most of the variation between quotes.
- Site list. Addresses, number of floors and approximate area per site.
- Floor plans. Current drawings in a usable format, with any known changes.
- Purpose. New design, fault finding or validation, which determines the survey type.
- Design target. Number of users and devices, applications and any special devices.
- Access. Hours, escorts, safety induction and restricted areas.
- Deliverables. Heatmaps, access point schedule, cabling and power requirements, bill of materials, follow-up validation.
- Next step. Whether the supplier will also install, or whether the survey feeds a tender.
With that, ask each supplier to state what is included, what is charged separately (travel, out-of-hours work, re-visits) and whether the survey fee is credited against installation.
Our perspective
We see survey cost as the cheapest part of a wireless project and the part that most affects the rest of it. A design based on measured or well-modelled data tells you how many access points to buy, where the cables go and what the network will achieve. Without it, the cost reappears as extra access points, cable reruns and complaints after go-live.
Our approach is to match the method to the risk. We use predictive surveys where drawings and construction are reliable, and on-site passive and active surveys where the environment is complex or the application is critical. As a Cisco partner with over 35 years of experience, our certified consultants design for the sectors we work with every day: education, manufacturing, logistics, hospitality and shared workspaces.
We keep the process transparent. You get a clear scope, a stated list of deliverables and a report your own team or any installer can use. Because survey scope varies so much between buildings, we quote against your site rather than publish a rate that will not fit it.

FAQ
How much does a WiFi survey cost in the UK?
The price depends on survey type, floor area, building construction, number of sites and report depth. Predictive surveys cost less than on-site surveys because they need no site time. Because every building differs, a reliable figure comes from a quote based on your floor plans and requirements.
What is the difference between a predictive and an on-site survey?
A predictive survey models coverage in software from your floor plans and building data, usually without field measurements. An on-site survey takes real measurements in the building with specialist equipment. Predictive suits design and budgeting, while on-site suits complex spaces, fault finding and validation.
Is the survey fee credited against installation?
That depends on the supplier and the contract. Ask for it to be stated in writing when you request the quote, along with whether travel, out-of-hours work and re-visits are included.
How long does a WiFi site survey take?
It depends on the area and the method. A predictive survey is a desk exercise, while an on-site survey of a larger or multi-floor site can take several days including analysis and reporting. Your supplier should give a timeline with the quote.
Do I need a survey if I already have access points installed?
If users report dropouts, slow speeds or dead spots, an active or passive survey of the existing network identifies the cause. A survey is also worth doing before any refresh, so that new equipment is placed against measured conditions.
