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.

Our Hampshire engineers are different — they've worked in the area for years, know the roads, know the property types, and have solved the exact same signal challenges you might be facing dozens of times before. That accumulated local experience makes a measurable difference to the quality of every installation.

Common Signal & Installation Challenges in Portsmouth

Rowridge transmitter on the Isle of Wight provides Portsmouth's Freeview signal across the Solent — the maritime crossing creates no meaningful signal attenuation under normal conditions
Portsea Island's densely packed Victorian terraces, particularly in Fratton and Landport, present complex cable routing challenges and shared system faults
Portsmouth's Historic Dockyard, Gunwharf Quays, and Spinnaker Tower area are directly exposed to Solent salt air — aerial equipment here has a demonstrably shorter service life than inland installations
Southsea seafront properties face onshore winds directly off the English Channel — without stainless steel fixings and sealed entry points, corrosion failure typically occurs within two years

Portsmouth Installation Tips from Our Engineers

Marine-specification aerials, marine-grade coaxial cable, and stainless steel fixings should be the default specification for any Portsmouth property within 500 metres of the seafront
Portsea Island's high property density means shared aerial systems on larger HMO and converted properties in Landport and Fratton are often more cost-effective than individual runs
Portsmouth historic building stock, including Georgian and Victorian naval housing near the dockyard, frequently requires specialist fixings to avoid masonry damage on listed structures

Rated 4.8 out of 5 from over 1,200 verified reviews on Google, Trustpilot and Checkatrade.

★★★★★ Paul F.

"Got a quote from three companies — Everest were mid-range on price but by far the most professional. The installation quality is excellent. Would definitely use again."

★★★★★ Karen B.

"My satellite dish was misaligned for months. The engineer fixed it in under an hour, tested every channel and even checked my aerial at the same time. Great service."

★★★★★ Thomas N.

"Used Everest for a full home CCTV installation. Four cameras, full app setup, all cables hidden neatly. Excellent job and the price was exactly as quoted."

TV Aerial Installation in Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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 Portsmouth

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.
