One contractor, one handover

Cabling and Wi-Fi, done properly.

From a handful of data points to a whole-site network, we install neatly, label everything and hand over a network that performs — with the paperwork to match.

FAQ

Data & networking questions.

Can you cable a whole building?

Yes — we install full Cat6 structured cabling, comms cabinets, PoE switching and Wi-Fi for offices, schools, surgeries, factories and libraries, with one handover pack.

Do you install commercial Wi-Fi?

We install and configure commercial-grade Wi-Fi (Reyee/Ruijie) with access points sited for real coverage across the whole site.

Do you do fibre?

We install fibre optic links between buildings and cabinets where distances or speeds need it.

Do you install Wi-Fi and wireless access points?

Yes. We design and install whole-site Wi-Fi for homes and businesses across Mid Somerset. We work with Ubiquiti UniFi, Cisco Meraki, TP-Link Omada and Ruckus. Every installation starts with a site survey so the number and position of access points match the actual coverage and density you need.

What is the difference between Cat6 and Cat6a?

Cat6 supports 1 Gbps at the full 100m and 10 Gbps up to about 55m. Cat6a supports 10 Gbps at the full 100m. For any new install we recommend Cat6a as the default — future-proofs for Wi-Fi 6E/7 access points, 4K IP CCTV and 10 Gigabit to the desk. The cable cost difference is small; the cost of re-cabling later is not.

How many access points do I need?

It depends on floor area, construction (stone walls and foil-backed plasterboard kill Wi-Fi), and device density. As a rough guide: one WAP per 100–120m² open-plan office, one per floor in a 3-bed domestic, one per 40–60m² in a high-density environment like a café or gym. We do a proper site survey with a spectrum analyser before quoting.

Can you extend my home Wi-Fi to cover the upstairs and garden?

Yes. We wire Cat6a back to a central switch and install ceiling-mount access points with PoE — a much better solution than plug-in range extenders or mesh pods. Real whole-home coverage, a single SSID you roam between without dropping, and a separate guest network if you want one.

Do you certify the cabling?

Yes. Every link is tested and certified with a cable tester to TIA-568 Category 6 or 6a permanent-link limits. You get a PDF test report per port at handover. No cheap continuity-tester-only jobs. This is the same standard any major datacomm contractor is held to.

Can you migrate an old Wi-Fi setup without downtime?

Yes. We install the new access points in parallel on a separate VLAN, bring them up, verify coverage and throughput, then cut the old kit over in a planned short window — usually done out of hours for commercial sites. Staff keep working, the changeover is minutes, not days.

Do you work with existing IT providers?

Very often. We handle the physical side — cabling, containment, cabinet build, access point mounting, PoE switching, cable certification — and hand the configured ports over to your IT team. We can also pre-configure managed switches and controllers if you want us to take the full install end-to-end.

Design · Install · Certify

Cabled. Wireless. Certified.

A modern network is both — structured copper and fibre running everything that has to be fast, stable or secure, plus wireless access points layered on top for the kit that has to roam. We do both halves. Every cable terminated to TIA-568, every Wi-Fi network designed off a proper site survey, every handover with a full test pack.

01

Structured cabling — Cat6 / Cat6a

Cat6 supports 1 Gbps at the full 100m and 10 Gbps up to about 55m — fine for most homes and small offices. Cat6a supports 10 Gbps at the full 100m and is the right specification for Wi-Fi 6E/7 access points, 4K IP CCTV, and any site that expects to still be there in fifteen years. We recommend Cat6a as the default for new builds and refurbishments — solid (in containment) and stranded (patch leads), LSZH-sheathed for commercial, U/UTP or F/UTP depending on noise environment.

02

Fibre optic backbones

Fibre is the right choice for inter-building links, long runs over 90m, noise-critical environments, and any site where copper just isn’t appropriate. We are City & Guilds Level 3 Fibre Optic Installation (3667) qualified — fusion splice with Fujikura, OTDR test, and issue a channel test report. Multimode OM3/OM4/OM5 for in-building, singlemode OS1/OS2 for campus and long-distance. Full fibre detail →

03

Wi-Fi access points

Ceiling-mount access points on PoE, back-hauled over Cat6a to a central switch. One SSID across the whole site, seamless roaming between APs, optional guest network on a separate VLAN. We design and install Ubiquiti UniFi (strong price-to-performance for homes, bars, SMB), Cisco Meraki (cloud-managed, right for multi-site commercial), TP-Link Omada (good budget managed option) and Ruckus (high-density venues).

04

Wi-Fi site surveys

Before we quote a wireless job we survey the site. Floor plan, construction types (stone walls and foil-backed plasterboard kill 5 GHz), interference sources, device density and throughput requirements. We use a spectrum analyser and predictive design software, not guesswork. You get a heat-map showing predicted signal strength at each AP, a bill of materials, and a fixed-price quote. No rip-out-and-start-again calls six months later.

05

PoE switches & cabinets

Managed switches to run the whole thing. We spec for PoE+ (30W per port) or PoE++ (60–90W per port) depending on whether you are running access points, IP phones or 4K PTZ CCTV. VLAN-capable for guest / IoT / CCTV separation on day one. Cabinets from 6U wall-mount up to full-height floor-standing — patched, dressed, labelled, and fitted with a proper cooling and power arrangement, not a heap of spaghetti behind a door.

06

Patch panels & faceplates

1U and 2U 24-port patch panels for cabinets, single- and dual-gang RJ45 wall plates for desk drops, angled patch panels for dense environments. Keystone jacks from Excel, Hellermann, CommScope and Brand-Rex. Labelled both ends to match the cable test sheet.

07

Cable testing & reports

Every link tested to TIA-568 Category 6 or 6a permanent-link limits per port — wire-map, continuity and length. Not a cheap continuity-tester-only job. Every port gets a PDF test report at handover.

08

Domestic Wi-Fi, done properly

Stone cottages, extensions, detached garages, home offices, home gyms. Mesh pods and plug-in range extenders always disappoint. We wire Cat6a from the router to one or more ceiling-mount UniFi access points — usually one per floor, plus an optional outdoor AP for garden coverage. One SSID, seamless roaming, separate guest network for visitors. Typically from £450–£950 for a three-bed install; more for larger or harder-to-cable properties.

09

Commercial Wi-Fi & guest networks

Office, retail, hospitality, clinics, gyms, care homes, holiday lets. Staff Wi-Fi on one VLAN, guest on another with captive-portal sign-in and content filter, IoT/CCTV on a third. Everything cloud-managed so you can see what’s happening from a laptop. Also: pre-authorised device lists, schedule-based access (e.g. Wi-Fi disabled at 11pm), bandwidth shaping so Netflix doesn’t kill the point of sale, and full event logging.

10

Existing network diagnostics

Got a network that used to work? Slow on one floor, randomly drops, VPN keeps disconnecting, one desk gets 100 Mbps while the one next to it gets 1 Gbps? We test existing cabling to find dead pairs, bad terminations and split pairs, run spectrum analysis of existing Wi-Fi for channel conflicts and interference, review switch logs and error counters, and give you a written report with fix priorities. We’d rather fix it than replace it if replacing isn’t warranted.
