Will a WiFi extender fix my dead spots?

Rarely, reliably. Extenders create a separate network — your devices do not automatically switch between the router and the extender, causing drops when you move between them. A mesh system or wired access point provides seamless roaming and is almost always the better solution.

What is wired backhaul and why does it matter?

Wireless mesh nodes communicate with your router over WiFi, which halves the available bandwidth for devices. Wired backhaul connects each node to the router via an Ethernet cable through the loft, eliminating this penalty and roughly doubling mesh performance. We install this as standard wherever the property allows.

Which mesh system should I buy?

We are hardware-agnostic. For most homes we recommend Eero Pro, TP-Link Deco or Google Nest WiFi Pro depending on home size and your ISP router's compatibility. For larger or more complex homes with wired backhaul, Ubiquiti UniFi provides the highest performance. We advise after surveying your home.

Can you fix WiFi in a new build where the signal is poor from the start?

Yes. New builds often have poor WiFi coverage because the router is installed in a single utility cupboard serving a two or three-storey property. We design and install the correct solution — typically a 2 or 3-node mesh system with wired backhaul through the first-fix cabling.

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.

How We Work — WiFi Optimisation & Mesh Networks in Barnet

Step 1: We survey WiFi signal levels in every room to identify exactly where coverage fails and what the physical cause is
Step 2: Router position is assessed — most routers are installed by ISPs in the wrong location for whole-home coverage
Step 3: Mesh nodes are positioned for maximum coverage overlap, with wired backhaul via Ethernet cable run through the loft wherever practical
Step 4: The network is configured for seamless roaming — your devices follow the strongest node automatically without manual switching
Step 5: Speed and signal are verified in every room before we leave, including the problem areas that prompted the installation

TV Aerial Installation in Barnet

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 Barnet

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 Barnet

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 Barnet

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 Barnet

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 Barnet

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 Barnet

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 Barnet

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 Barnet

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 Barnet

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 Barnet

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.
Smart Home Setup in Barnet

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.
Data Cabling & Structured Networks in Barnet

A wired Ethernet connection delivers consistently lower latency, higher speed and more reliable performance than any WiFi solution. For home working, 4K streaming to multiple rooms, online gaming and network storage, structured data cabling is the most effective long-term infrastructure investment you can make in your home.
Gutter Cleaning & Repairs in Barnet

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.
