What is the difference between Cat5e, Cat6 and Cat6a?

Cat5e supports Gigabit (1 Gbps) speeds. Cat6 supports 10 Gbps on runs up to 55m and is the standard for new home installations. Cat6a supports 10 Gbps on runs up to 100m and is recommended for home offices, media rooms and future-proofing. We recommend Cat6 for most domestic installations.

How much disruption will data cabling cause?

We route cables through loft spaces and under floors wherever possible. In most homes, cable runs require only minor decoration — typically making good around a single wall plate in each room. We discuss the route and any redecoration implications before starting.

Can you install data points alongside TV aerial points?

Yes, and we frequently do. Both cable types run the same routes through loft space. Combining aerial and data cabling in a single visit saves time, reduces disruption and takes advantage of the same cable paths.

Do I need a network switch or just a router?

A standard home router typically has 4 Ethernet ports. If you are installing more than 4 wired points, you need a network switch — an unmanaged Gigabit switch from £20, or a managed switch for more control. We advise on the correct switch specification during the planning stage.

Common Signal & Installation Challenges in Cardiff

Wenvoe transmitter, to the west of the city, provides Cardiff with some of the strongest Freeview signal levels in Wales — most city and bay postcodes receive excellent coverage
Cardiff Bay's regenerated waterfront gives outstanding satellite signal; properties near the Senedd benefit from both good aerial and dish coverage
Properties at the northern fringe of Cardiff, where the city meets the Valleys, experience progressively weaker signal and may require high-gain aerials or masthead amplification
Roath, Cathays, and Pontcanna's dense Victorian terraces occasionally produce IRS demand as purpose-built blocks are converted to multiple occupancy

Cardiff Installation Tips from Our Engineers

Standard Yagi aerials work reliably across Cardiff's inner suburbs — Wenvoe's proximity makes high-gain equipment unnecessary for the majority of properties
Cardiff Bay and Atlantic Wharf apartments require confirmed satellite access assessment before dish installation; not all balcony or roof positions provide a clear southern arc
For Valleys-fringe properties in Tongwynlais, Pentyrch, and Radyr, a professional signal survey identifies the correct aerial specification and prevents unnecessary amplifier installation

Local Signal Profile — Cardiff

Our engineers verify local transmitter conditions before specifying any equipment for Cardiff.

Primary transmitter	Wenvoe
Direction from Cardiff	south-west
Distance band	very close
Signal quality	Excellent

CF10 Cardiff city centre is exceptionally close to the Wenvoe transmitter on the Vale of Glamorgan escarpment, giving among the strongest Freeview signals in Wales

Impact on your installation: The excellent signal from Wenvoe gives Cardiff properties a solid foundation — our engineers can specify the right equipment with confidence for your exact location.

TV Aerial Installation in Cardiff

A correctly installed digital aerial is the foundation of reliable Freeview reception. Our engineers carry Ofcom-approved wideband aerials, high-gain models and loft-mounting kits — and always test signal strength before and after installation to confirm full HD channel reception on every multiplex.
Satellite Dish Installation in Cardiff

Whether you want Sky Q, Freesat or foreign satellite channels, precise dish alignment is everything. A dish a single degree off true south loses half its signal in poor weather. Our engineers use professional-grade signal meters to align every dish to the exact azimuth and elevation for your satellite — never by eye.
TV Wall Mounting in Cardiff

TV wall mounting is not simply bolting a bracket to the wall. Wall type, stud location, cable concealment, HDMI routing and viewing angle all need careful consideration. Our engineers handle every element — leaving a clean, professional result with no visible cables and the screen at the correct height for comfortable viewing.
CCTV Installation in Cardiff

A CCTV system is only as effective as its camera placement. Cameras positioned for ease of installation rather than coverage provide an incomplete picture and limited deterrent value. Our engineers assess your property first — identifying entry points, blind spots and the optimal camera positions — before selecting any equipment.
Smart CCTV & Doorbell Cameras in Cardiff

Smart video doorbells and outdoor cameras from Ring, Google Nest, Eufy and similar brands are straightforward to buy but often poorly installed. Correct camera angle, a reliable WiFi connection at the installation point, and proper app configuration are all critical for the system to work as advertised.
Aerial & Satellite Repairs in Cardiff

Signal faults almost always have a specific, identifiable cause. Our engineers carry calibrated test meters and the most common replacement parts on every van — most faults are diagnosed and resolved in a single visit without the cost of a follow-up appointment.
Multi-Room TV Systems in Cardiff

A correctly designed multi-room TV system lets every TV in your home tune to a different Freeview channel simultaneously — without the interference or quality loss of cheap signal splitters. Our engineers specify the correct amplifier for your number of outlets and test signal level at every point before completion.
Starlink Installation in Cardiff

Starlink performance depends almost entirely on the dish having a clear, unobstructed view of the northern sky. A poorly sited dish with even partial obstruction can halve throughput and cause frequent outages. Our engineers use the Starlink obstruction app to survey multiple positions before any mounting work begins.
Wireless Alarm Installation in Cardiff

A wireless alarm that generates false activations quickly gets turned off and never used again. Correct PIR sensor placement, appropriate alarm grading and properly configured monitoring make the difference between a system that genuinely protects your property and one that becomes a source of frustration.
Commercial Installation Services in Cardiff

Commercial TV distribution, CCTV networks, data cabling and AV systems for hotels, offices, care homes and retail premises require system design, project management and careful scheduling around operational requirements — all of which our commercial team provides as standard.
Soundbar & Home Cinema Setup in Cardiff

Most soundbars underperform not because of their quality but because of how they are set up. HDMI ARC settings incorrectly configured, Dolby Atmos passthrough disabled on the TV, subwoofer positioned in a room corner for convenience rather than acoustics — all common, all easy to fix with the right knowledge.
WiFi Optimisation & Mesh Networks in Cardiff

WiFi dead spots almost never have anything to do with your broadband speed. The cause is almost always physical — walls, floors, the distance between your router and the devices that need it most. The solution is either a correctly placed access point or a mesh system with nodes positioned to eliminate the specific dead zone, not just placed wherever is convenient.
Smart Home Setup in Cardiff

Most smart home frustration comes from devices from different manufacturers that were never designed to work together, placed on the wrong platform, or set up without automations that make the technology genuinely useful. Our engineers untangle these integrations and set up the automations that make a smart home actually smart.
Gutter Cleaning & Repairs in Cardiff

Blocked gutters are one of the most common and most preventable causes of damp, foundation damage and fascia rot in UK homes. Most properties need gutter cleaning twice a year — once after autumn leaf fall and once in spring — to prevent the water ingress that causes expensive structural repairs.
