How much does a business Wi-Fi installation cost in the UK?

Why pricing is so hard to find

Search for business Wi-Fi installation costs and you'll find a lot of "contact us for a quote" and very little actual data. That's partly because the range is genuinely wide – a two-access-point install in a small office bears almost no resemblance, commercially or technically, to a 60-access-point deployment across a multi-floor building with conduit runs and a managed service wrapper.

The other reason is that some suppliers prefer not to anchor expectations before they've scoped the job. That's understandable, but it puts buyers in a weak position when comparing proposals. This article gives you the context to interpret quotes intelligently, not just collect them.

The main cost factors

Every Wi-Fi installation quote breaks down into the same fundamental components. Understanding what each one covers – and where costs vary – is the starting point for any sensible budget conversation.

Site survey. A professional wireless survey measures signal propagation, identifies interference sources and determines where access points should be placed to achieve the coverage and capacity you need. It's the foundation of a well-designed network. Some suppliers include this in the project cost; others charge separately, typically £300–£600 for a small-to-medium site. We'll come back to what happens when it's skipped.

Number of access points. An access point (AP) is the hardware unit – typically ceiling-mounted – that provides wireless coverage in a zone. AP count is the single biggest driver of both hardware and labour cost. How many you need depends on your floor area, building construction (concrete and thick walls attenuate signals heavily), the density of connected devices and whether you need coverage in outdoor areas, car parks or outbuildings.

Cabling. Every access point needs a wired connection back to your network switch – either existing cabling that can be reused, or new structured cabling runs. In a refurbishment or new build where Cat6A cable is being installed as part of the project, Wi-Fi cabling is often included in the overall cabling scope. In a retrofit into an occupied building, cable runs through ceilings, walls and risers add labour cost and can be the largest single line item. Cabling is frequently quoted separately from the wireless installation – make sure any quote you receive is explicit about whether it's included.

Hardware tier. Business Wi-Fi hardware spans a wide range. Consumer-grade access points (the kind you'd buy from a high-street electronics retailer) are at one end; enterprise-grade equipment from vendors like Cisco Meraki, HPE Aruba, Ubiquiti UniFi and Ruckus is at the other. The hardware tier affects both upfront cost and long-term performance – more on this below.

Controller and management software. Business-grade Wi-Fi systems are managed centrally through a wireless controller – either a physical appliance on your network or a cloud-based platform. This lets you configure all your access points consistently, push firmware updates, monitor performance and manage guest networks or bandwidth policies from a single interface. Some vendors include controller software in the hardware price; others charge a per-AP annual licence (typically £30–£80 per AP per year for cloud management).

Installation labour. This covers the time to mount access points, terminate cabling connections, configure the controller, set up SSIDs and VLANs (Virtual Local Area Networks – logical partitions of the network that separate, say, guest traffic from internal systems), test coverage and hand over the system. Labour rates vary by region and supplier, but a single-day installation for a small office and a multi-day project for a large site are both common.

Ongoing managed service. Many businesses choose to have their Wi-Fi managed post-installation – covering proactive monitoring, firmware updates, troubleshooting and support. Managed service fees are typically charged per access point per month, ranging from £30 to £100 per AP depending on the service level. This is recurring cost that doesn't appear in a one-off installation quote but should be factored into your total cost of ownership.

Indicative price ranges by business type

These ranges reflect typical UK market pricing for a competently designed and installed system using business-grade hardware. They exclude VAT and, unless stated, assume cabling is either reused or included.

Small office – up to 20 staff, single floor: £1,500–£4,000. A small professional services or financial services office in a standard commercial unit typically needs two to five access points. If existing data cabling points are usable, installation is straightforward. The upper end of this range reflects new cabling runs or a higher-specification hardware choice.

Medium office – 50–100 staff, multi-floor: £5,000–£12,000. Multi-floor deployments require inter-floor cabling, more access points and more careful RF design to avoid co-channel interference between floors. Controller configuration is more involved. Budget more time for the site survey and commissioning at this scale.

Hospitality venue – hotel, restaurant, multi-zone: £8,000–£25,000+. Hospitality is one of the most demanding Wi-Fi environments. High device density, the need for network segmentation between guest, staff and back-of-house systems, outdoor coverage and often ageing building fabric drive both AP count and cabling complexity. Large hotels can exceed the upper end of this range significantly. The investment is hard to avoid – guest Wi-Fi quality directly affects review scores.

Warehouse or manufacturing facility: £6,000–£20,000+. Large open volumes, metal racking and machinery create coverage and interference challenges that office environments don't. RF signals behave differently in a warehouse – you might cover a larger floor area per AP in open space but then find that racking creates dead zones that require additional units. Outdoor-rated or ruggedised access points for loading bays and yard areas add cost. A proper site survey is especially important here.

What's included – and what's extra

Not all quotes scope the same work. When you're comparing proposals, check each of these specifically.

• Site survey: sometimes included in the project cost, sometimes a separate line (£300–£600 for small-to-medium sites). A quote without a survey is a guess.
• Cabling: often quoted separately by a structured cabling contractor. Confirm whether cable runs to each AP location are in or out of scope.
• Hardware warranty and support: enterprise vendors typically offer three to five year warranties; confirm what's included and what a replacement unit costs if an AP fails.
• Controller licences: cloud-managed platforms often carry annual per-AP fees. These can add £50–£80 per AP per year indefinitely – that's £500–£800 per year on a 10-AP system.
• Managed service: post-installation monitoring and support is a separate ongoing cost. If you want your supplier to proactively manage the network rather than respond reactively to problems, expect £30–£100 per AP per month depending on SLA.
• Guest portal or captive portal: branded landing pages and authentication for guest Wi-Fi are available on most platforms but may require additional configuration time or a separate software licence.

Wi-Fi 6 vs Wi-Fi 7: which should you specify in 2026?

Wi-Fi 7 (802.11be) is now available from all major enterprise vendors. Wi-Fi 7 hardware typically costs 20–40% more per access point than equivalent Wi-Fi 6 hardware – a meaningful difference on a large project.

For new installations in 2026, we'd recommend Wi-Fi 7 for most projects. The argument is simple: the technology cycle for enterprise Wi-Fi infrastructure runs seven to ten years. Specifying Wi-Fi 6 today to save 20% on hardware means you're installing a standard that's already two generations old. Wi-Fi 7's Multi-Link Operation (MLO) – the ability for devices to transmit across multiple radio bands simultaneously – significantly improves performance in high-density environments, and device support is growing quickly. You'd be investing in hardware that needs replacing several years sooner.

The exception is if you're replacing a genuinely failing network and budget is constrained. Wi-Fi 6 hardware installed to a good design still outperforms Wi-Fi 5 (802.11ac) substantially. A well-designed Wi-Fi 6 network is far better than a poorly designed Wi-Fi 7 one.

Consumer vs business-grade hardware: why it matters

A £150 consumer router from a supermarket will provide Wi-Fi. It won't provide business Wi-Fi – and the difference becomes apparent quickly in any environment with more than a handful of devices or any serious operational dependency on connectivity.

Consumer access points are built for households: a small number of devices, occasional use, and an owner who can power-cycle the router without it affecting anyone's work. They're not built for the continuous load of a 50-person office, the density of a hotel corridor or the reliability requirements of a production environment running Wi-Fi-dependent barcode scanners.

Specifically, consumer hardware typically lacks:

• Adequate DHCP capacity: the mechanism for assigning IP addresses to devices has a finite limit. Low-end routers can run out of addresses in a busy office, causing devices to fail to connect.
• Centralised management: there's no controller to configure all devices consistently, push updates or monitor the network.
• Quality of Service (QoS): the ability to prioritise traffic types – so a VoIP call isn't degraded by a large file download happening simultaneously.
• VLAN support: separating guest traffic from internal systems requires VLAN capability that most consumer hardware doesn't support properly.
• Vendor support and SLA: if a business-grade AP fails, you can get a replacement unit. Consumer hardware has no equivalent support structure.

Business-grade vendors worth specifying include Cisco Meraki, HPE Aruba, Ubiquiti UniFi and Ruckus. Each has different pricing tiers, management models and strengths – the right choice depends on your environment and support requirements.

How to get an accurate quote

The process matters as much as the price. A quote from a supplier who has walked your building, measured signal propagation and produced a coverage design will be more accurate – and more defensible – than one produced from a floor plan and an AP count estimate.

A good site survey for a business Wi-Fi installation should cover:

• Walkthrough of all areas requiring coverage, including outdoor spaces and any areas with unusual construction or interference sources
• Assessment of existing cabling infrastructure and whether it's reusable or needs replacement
• Identification of interference sources – neighbouring networks, microwave ovens, Bluetooth-dense areas, industrial equipment
• AP placement recommendations with reasoning – not just a count but a proposed layout
• Backhaul infrastructure assessment – confirming your switches and cabling can support the APs being proposed

When comparing quotes, ask each supplier: what assumptions are you making about my building? Which hardware are you proposing and why? What's the basis for your AP count? Is cabling in or out of scope? What does post-installation support look like?

Wide variation between quotes – say, £3,000 versus £9,000 for what appears to be the same project – almost always means the proposals aren't scoping the same work. The lower quote has usually made assumptions the higher one hasn't.

Red flags when reviewing quotes

A few patterns are worth treating as warning signs rather than competitive advantages.

• No site survey mentioned. A supplier who quotes Wi-Fi from a floor plan alone is guessing. Coverage problems after installation are expensive to fix – additional cable runs, additional APs, return visits.
• No mention of cabling. If a quote doesn't address how each access point will be connected back to your network, either it assumes your existing cabling is adequate (which may not be true) or cabling is excluded and will appear as a surprise additional cost.
• Consumer hardware quoted for a business environment. If the quote lists hardware you can buy from Amazon for £100, question why. It's not a saving – it's a different product category that won't perform adequately or support professionally.
• Lowest price, no explanation of design decisions. Cheap installations that skip the survey, use underspecified hardware or exclude cabling often result in a second, more expensive installation within two to three years. The true cost of a bad Wi-Fi installation isn't the invoice – it's the lost productivity, the complaints and the cost of doing it again properly.
