WiFi Heat Map Survey
Data-driven WiFi optimisation
See Your WiFi Performance
Before installing a single access point, we conduct a professional WiFi heat map survey that visualises coverage, identifies dead zones, and pinpoints sources of interference. This data-driven approach ensures your network is designed correctly from the start, eliminating the frustration of poor connections and buffering streams.
Our survey reports include detailed floor plans with signal strength overlays, channel recommendations, and capacity analysis. You will see exactly where coverage is strong, where it is weak, and what we recommend to fix it. This transparency ensures you understand the design decisions and can have confidence in the proposed solution.
For luxury properties in Chelsea, Kensington, and Mayfair where neighbouring WiFi networks create significant interference, our spectrum analysis identifies the cleanest channels and optimal access point placement. For country estates in Virginia Water and Cobham where buildings are spread across large grounds, we design outdoor coverage and point-to-point links that extend the network to outbuildings, stables, and garden rooms.
What Our Survey Delivers
Coverage Mapping
Visual heat maps showing signal strength in every room and corner of your property.
Interference Analysis
Detection of neighbouring networks and non-WiFi interference sources such as Bluetooth and microwaves.
Speed Testing
Throughput measurement at multiple locations to verify actual performance, not just signal strength.
Capacity Planning
Analysis of connected device density and bandwidth requirements for your specific usage.
Detailed Report
Professional PDF with recommendations, diagrams, equipment lists, and installation guidelines.
Post-Installation Validation
Follow-up survey after installation to verify coverage and performance targets are met.

WiFi Survey FAQs
What is a WiFi heat map survey?
A WiFi heat map survey is a professional analysis of wireless signal coverage throughout your property. Using specialised software and calibrated hardware, we walk every room and record signal strength, interference, and data rates. The results are plotted on your floor plan as a colour-coded heat map, showing exactly where coverage is strong, weak, or non-existent. This data-driven approach eliminates guesswork and ensures your network is designed for optimal performance.
Why do I need a WiFi survey before installing a network?
Without a survey, network installation is based on guesswork. You might place access points in suboptimal locations, miss dead zones, or create interference by using overlapping channels. A survey identifies the exact number and placement of access points needed, the best channels to use, and any sources of interference such as neighbouring networks, microwave ovens, or Bluetooth devices. The result is a network that works correctly from day one, with no costly revisions.
What does your WiFi survey report include?
Our survey report includes colour-coded heat maps for signal strength, signal-to-noise ratio, and data rate coverage. We also provide channel recommendations, interference analysis, capacity planning for connected device density, and a detailed equipment list with model numbers and quantities. The report concludes with specific recommendations for access point placement, antenna orientation, and power settings. For commercial clients, we add roaming analysis and capacity projections.
Can you survey a property before construction is complete?
Yes, and this is the ideal scenario. We conduct predictive surveys using your architect's floor plans and material specifications. The software models how different building materials, such as concrete, steel, and glass, will affect signal propagation. This allows us to specify cable routes, ceiling mounting locations, and power requirements before walls are closed. Post-construction, we perform a validation survey to confirm the network performs as designed.
How long does a WiFi survey take?
A residential survey for a typical four-bedroom home takes two to three hours, including setup, measurement, and report generation. Larger properties with multiple buildings or complex layouts may require a full day. Commercial surveys for offices, hotels, or warehouses depend on the size and complexity, typically ranging from one day to several days. We provide time estimates when booking your survey.
What equipment do you use for WiFi surveys?
We use professional-grade survey equipment including Ekahau Sidekick spectrum analysers, iBwave RF planning software, and calibrated WiFi adapters. These tools measure not just signal strength, but also channel utilisation, interference from non-WiFi sources, and multi-path propagation effects. Consumer apps and smartphone-based tools cannot match this accuracy and are not suitable for professional network design.
Which areas do you cover for WiFi surveys?
We provide WiFi heat map surveys throughout London and the Home Counties. In London we cover all postcodes including Chelsea, Kensington, Mayfair, Notting Hill, Hampstead, Belgravia, Knightsbridge, Islington, and Canary Wharf. In Hertfordshire we serve St Albans, Watford, Rickmansworth, and Harpenden. In Surrey we cover Guildford, Weybridge, Cobham, and the Wentworth Estate. We also travel to Berkshire, Buckinghamshire, and Oxfordshire for larger projects.
