WiFi that covers the whole building, not just near the router
Most WiFi problems aren’t a bad router, they’re a coverage design problem nobody solved before the access points went up. We survey first, design second, install third.
Built for the environment, not a generic spec sheet
Offices
Full-floor coverage designed around your actual building, not a rule of thumb applied blind.
Warehouses & industrial sites
Wireless coverage that accounts for metal racking and structural interference most office-grade designs ignore.
Schools & campuses
High-density coverage for classrooms and halls where hundreds of devices connect at once.
What wireless network installation costs
Indicative ranges, supplied and installed. Every project is scoped individually, this is a starting point for budgeting, not a quote.
| Configuration | Typical use | From |
|---|---|---|
| Wireless site survey & design | Per site | £450 +VAT |
| Access point supply & install | Per AP, PoE-powered | £250 +VAT |
| PoE switch & AP bundle | Small office, 4 to 6 APs | £1,650 +VAT |
| WiFi 6E/7 upgrade | Per AP, high-density sites | £395 +VAT |
Public sector and education purchase orders accepted.

WiFi Installation: Answered Plainly
How many access points does my office actually need?
As a starting rule of thumb, one access point covers roughly 2,500 to 3,000 sq ft of typical office space, fewer in open-plan areas, more where partitions or dense client counts reduce range. A proper site survey gives an exact figure rather than a guess.
Do we need WiFi 6E or 7, or is WiFi 6 enough?
For most 2026 office deployments, WiFi 6 remains the pragmatic default, it works with every existing device and costs meaningfully less than 6E or 7. WiFi 6E/7 earns its premium in high-density environments with genuinely 6GHz-capable client devices.
Does our cabling need to change for new WiFi 7 access points?
Often yes, higher-end WiFi 7 access points can require PoE++ power delivery and Cat6A cabling to perform properly, which is worth checking before ordering hardware rather than after.
Have a network, cloud or CCTV project in mind?
Tell us the environment and the outcome you need, we’ll tell you what’s realistic.
Can existing WiFi be upgraded without replacing the whole system?
Often yes. If the underlying cabling and PoE capacity support it, individual access points can be swapped for a newer standard without redesigning the whole layout. Where the original design was already thin on coverage, a partial upgrade sometimes just makes the existing weak spots more obvious, so a fresh survey before committing to an upgrade is usually worthwhile.
Do you provide guest WiFi separate from the main business network?
Yes, as standard on most installations. Guest WiFi is set up on its own VLAN, isolated from the business network, so visitors can get online without any access to internal systems, printers or file shares.
Does a WiFi installation project include a proper site survey, or just an estimate of access point numbers?
Yes, a physical or predictive site survey is carried out before access point placement is finalised, mapping likely coverage and interference across the building rather than estimating numbers from a floor plan alone, so the finished install matches how the space is actually used.
