Business Wi-Fi installation

Whether it is one office floor or a warehouse, a hotel or a school, every business Wi-Fi installation we run follows the same steps:

1. Survey. An Ekahau survey of the building as it really is, or a predictive design from drawings for a fit-out. SEGwifi is an Ekahau partner.
2. Design. Access point positions, channel plan, capacity for the number of people and devices, and the cabling and containment needed to reach every position.
3. Equipment. We are vendor-neutral and install Cisco Meraki, Ruckus, Aruba and Cambium and Ubiquiti UniFi, chosen to fit the site and the budget.
4. Installation. Containment, Cat6A and fibre, cabinets, access points and power, by our own engineers. We are part of an electrical contractor, so power and containment are our day job.
5. Commissioning. SSIDs, VLANs, guest access, roaming and security set to the design, not left on defaults.
6. Validation. We survey it again after go-live and compare it with the design, then hand over the evidence.
7. Support. Optional managed Wi-Fi afterwards, so someone is watching the network and fixing problems before people notice them.

• Dallas Burston Polo Club: an events estate where over a thousand people come online at once, across several buildings and open ground.
• Beaulieu Enterprises: a five Gold Anchor marina, with coverage reaching out over the water.
• Magic Madhouse: dense racking and handheld scanners that have to hold their connection down every aisle.
• A five-storey townhouse office in Edinburgh: survey and design floor by floor.

We install business Wi-Fi across the UK from our base in St Albans, including business Wi-Fi installation in London and across Hertfordshire.

Ask anyone who has commissioned a Wi-Fi installation what went wrong and you will rarely hear "the design was bad". You will hear that the access points ended up somewhere else, that the cabling was late, that nobody could agree whose job the containment was, that the electrician and the network installer were on site in the wrong order, or that it all worked on the day and degraded within a month.

These are not design failures. They are hand-off failures, and they happen because the industry is structured to create them: the firm that surveys and designs is very often not the firm that installs, and neither of them owns the physical infrastructure the design depends on.

We removed the hand-off. The people who surveyed the building and drew the design are in the same business as the people who fix the containment, pull the cable, mount the access points, commission the radios and come back to validate the result. One programme, one set of paperwork, one number to ring.

Containment and cable routes

Tray, trunking, basket and conduit installed to the routes specified in the design — including at height, through plant spaces and across warehouse structures. This is the work that most often gets left unallocated between trades, and it is in scope from the start.

Structured cabling

Cat6A and fibre installed, terminated, tested and certified. Cabinets, patching and labelling done properly, because an unlabelled cabinet costs somebody a day the first time anything goes wrong. More on structured cabling.

Mounting and access

Access points mounted at the designed positions, heights and orientations. High-bay warehouses, atria and external positions need access equipment and working-at-height method statements — planned in advance rather than discovered on the day.

External access points from a job in October 2026: mounted under canopies and fed in galvanised conduit so the cable is protected outdoors.

Commissioning

Controllers, SSIDs, VLANs, channel plan, transmit power, roaming thresholds, band steering, guest policy and captive portal — configured to the design's commissioning sheet, not left on defaults. Default configuration is one of the most common causes of poor performance on otherwise good hardware.

Validation

We survey it again after commissioning and compare the result against the design, then hand you the evidence. That is what makes the coverage guarantee meaningful rather than decorative. More on validation surveys.

Handover

As-built drawings, cable test results, configuration documentation, labelling schedule and the validation report. Everything a future engineer — ours or yours — needs to work on the network without starting from scratch.

Almost every installation we do is in an occupied building. Warehouses that can't stop picking, schools in term time, hotels with guests in, care homes where residents live, offices where people are working. That constrains when and how the work happens, and it is normal rather than exceptional.

• Out-of-hours and phased working where the operation requires it — nights, weekends, shutdown periods, or floor by floor.
• RAMS as standard, with site-specific risk assessments and method statements issued before work starts.
• Accredited and insured. CHAS, Constructionline Gold, SafeContractor and TrustMark through The Specialist Electrical Group, with the site paperwork, insurance and induction records a main contractor or facilities team will ask for.
• Group capacity. Where a programme needs more hands on site to hit a date, we can draw on a broader range of engineers and installers rather than looking for a subcontractor at short notice.
• Clean handover. Containment finished properly, cabinets tidy and labelled, and the site left as we found it.
