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 Optimisation & Mesh Networks — Everest Aerials & Satellites

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 It Works — Whole-Home Mesh WiFi Installation & Optimisation

WiFi Survey & Dead Zone Mapping
Our network engineer surveys signal strength throughout your property — measuring on every floor and in every problem area — and maps dead zones to determine the correct number and placement of mesh nodes for complete coverage.
Wired Backhaul Installation Where Possible
Where feasible, we run Cat6 ethernet cable between mesh nodes to provide a wired backhaul connection. This eliminates the wireless signal loss that reduces mesh performance and ensures maximum throughput throughout every room.
Mesh Network Configuration & Optimisation
Nodes are configured with the correct SSID, band steering, and device prioritisation settings. We set up guest networks, parental controls where required, and optimise wireless channel selection for your property's specific environment.
Speed Testing in Every Room & Sign-Off
We run speed tests at multiple points throughout the property — including the rooms that previously had dead zones — to confirm coverage targets are met everywhere, document the results, and issue a guarantee on the installation.

Common Problems We Solve — WiFi Optimisation & Mesh Networks

Dead zones in bedrooms, garden room, or home office: Mesh nodes installed at optimal positions — full-strength WiFi confirmed in every problem room
WiFi extender creating a separate network devices will not roam between: Mesh system replacing the extender — single seamless network with automatic device roaming
Video calls dropping out from specific rooms in the house: Signal surveyed room by room — wired backhaul mesh node added to eliminate the dropout permanently
Smart home devices going offline because WiFi does not reach them: Coverage extended to every corner of the property — all smart devices connected and stable
Slow WiFi speeds despite a fast broadband package: Router position, channel selection, and ISP settings optimised — speeds benchmarked in every room
Garden office, garage, or outbuilding with no WiFi signal: Outdoor access point with wired backhaul installed — full-speed internet in the outbuilding

UK Transmitter Coverage — How Signal Conditions Affect WiFi Optimisation & Mesh Networks

Signal strength and quality varies significantly across the UK depending on your distance from the local Freeview transmitter, local terrain, and property type. Our engineers understand the transmitter landscape for your specific location — and specify equipment accordingly rather than using a one-size-fits-all approach.

London & South East	Crystal Palace	good to strong	Strong signal across Greater London; Hannington serves Berkshire/Surrey; Oxford transmitter covers Oxfordshire.
South West	Mendip	good to strong	Mendip serves Bristol, Bath and Somerset; Stockland Hill covers Devon; Caradon Hill serves Plymouth and Cornwall.
East of England	Sandy Heath	good to strong	Sandy Heath serves Bedfordshire, Hertfordshire and Essex; Tacolneston covers Norfolk and much of Suffolk.
East Midlands	Waltham	strong	Waltham transmitter delivers strong signal across Leicestershire, Nottinghamshire and Derbyshire; Belmont covers Lincolnshire.
West Midlands	Sutton Coldfield	excellent	Sutton Coldfield is one of the UK's most powerful transmitters — outstanding signal across the entire region; Ridge Hill supplements Herefordshire.
North West	Winter Hill	strong	Winter Hill on the West Pennine Moors delivers one of the UK's strongest Freeview signals across Greater Manchester, Lancashire and Merseyside.
Yorkshire & The Humber	Emley Moor	strong	Emley Moor's 330m mast gives outstanding coverage across virtually all of Yorkshire; Belmont serves the Humber and East Yorkshire areas.
North East	Pontop Pike	good to strong	Pontop Pike covers Tyne & Wear and County Durham; Bilsdale serves Teesside, North Yorkshire and the Moors.
Wales	Wenvoe	good	Wenvoe serves South Wales; Moel-y-Parc covers North Wales; relay stations supplement coverage in mountainous mid-Wales.

Our engineers carry signal metres to every job and measure actual signal strength and quality at your specific property before recommending any equipment. Find your local area page for transmitter-specific detail for your town.

Whole-Home WiFi That Actually Reaches Every Corner

WiFi extenders and powerline adapters are the wrong answer to a dead zone problem. Our engineers survey your property with WiFi analysis tools, design a mesh system that delivers full-strength coverage to every room, and configure all nodes before leaving. Every device in your home is tested and connected — and we benchmark speeds room by room to confirm performance before signing off.

WiFi survey before system is designed
Dead zones eliminated with mesh nodes
Speeds benchmarked room by room
All devices connected and tested
Router and ISP settings optimised

How We Work — WiFi Optimisation & Mesh Networks

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

WiFi Optimisation & Mesh Networks Cost

WiFi survey and optimisation consultation from £80. Mesh system installation (customer-supplied hardware) from £100. Supply and installation of a professional 2-node mesh system from £220. Data cabling for wired backhaul from £100 per run through the loft.

TV Aerial Installation
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
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
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
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
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
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
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
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
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
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
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
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
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
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.
