Think of wall jacks as the unsung heroes of a smooth digital life. They hide in plain sight but keep your internet steady, your TV picture crisp, and your landline clear. Even with Wi‑Fi and mobile data everywhere, a proper wired connection often means fewer dropouts, faster speeds, and less fuss. Whether you’re streaming 4K, running a home office, or fitting an entertainment wall, choosing the right phone and data jack matters more than you might expect.
If you’re shopping for sockets and modules, you’ll meet well‑known names like Click, Varilight, and Hamilton G2. These brands cover a wide range of finishes and technical options. For buying, specialist electrical stores such as Expert Electrical stock a broad selection, while mainstream retailers and trade suppliers like Screwfix, B&Q, Wickes, Toolstation, and City Electrical Factors are great if you want fast pickup or comparison shopping.
Expert Electrical focuses on electrical fittings and often carries the full range of faceplates and modules from leading brands. If you’re after specific finishes or hard‑to‑find modules, specialists like these make it easier to match parts and get the right technical spec.
Stores like Screwfix, Toolstation, and B&Q are convenient for DIYers and tradespeople alike. They stock a core range of RJ45, RJ11, coaxial, and HDMI outlet modules, and you can typically pick items up the same day. City Electrical Factors is geared more toward trade buyers and offers a deeper selection for larger installs.
There’s a surprising number of outlet types. The most common are RJ45 data sockets for Ethernet, RJ11 telephone jacks for legacy landlines, coaxial sockets for TV and satellite, and multimedia modules like HDMI plates. Picking the right type starts with understanding what each is built for and how it matches your cabling.
RJ45 outlets connect Cat5e, Cat6 or better cabling to your devices. They’re the go‑to for fast, reliable internet and are ideal for home offices, smart hubs, and media players. Look for outlets labelled Cat5e or Cat6 to match the cable you’ve run; the right pairing helps maintain advertised speeds.
RJ11 sockets are smaller and designed for traditional phone lines. Many modern homes still use them for alarm panels, fax machines, or secondary phone points. In mixed installs you’ll sometimes see combination faceplates that include both RJ45 and RJ11 modules.
Coax sockets handle TV aerials, digital boxes, and satellite feeds. You’ll find isolated and non‑isolated variants — isolated sockets can reduce earth loop noise for clearer pictures. If you’re wiring multiple rooms for TV, pay attention to the type of coax connector and whether it supports satellite LNB feeds.
Not all network wiring is created equal. Category ratings (Cat5e, Cat6, Cat6A) determine how much bandwidth the cable can handle, and shielding helps in environments with lots of electrical noise. Choosing the right combination depends on what you need now and what you want to future‑proof.
Cat5e is perfectly adequate for most home setups, supporting gigabit speeds at normal home lengths. Cat6 and Cat6A offer higher headroom and better performance for longer runs or denser installations. If you’re planning to move heavy data or anticipate future upgrades, Cat6 is a sensible compromise between cost and capability.
Shielded twisted pair (STP) adds a layer of protection against interference, which is useful near heavy machinery, large appliance wiring, or long cable runs. Unshielded (UTP) is cheaper and fine for most domestic environments. If you choose STP, make sure the faceplates and keystone jacks support the shield to keep the benefit intact.
A jack isn’t just technical — it’s part of the room. Brands like Click and Varilight offer decorative ranges with finishes such as stainless steel, brass, and different colours to match sockets and switches. Picking the right faceplate keeps your installation looking tidy and professionally coordinated.
Faceplates come in single gang, double gang, and multi‑module grids so you can combine Ethernet, TV, and HDMI in one location. Think about the future: a twin faceplate with spare modules gives flexibility for new devices without redoing the wall.
For telephone wiring, you’ll hear master and secondary sockets mentioned. The master is the first faceplate on the line and typically contains the network interface box or filter. Secondary sockets are downstream and are used for extra handsets or fax points — useful if you still rely on a landline somewhere in the home.
Installing jacks is straightforward for experienced DIYers but there are details that separate a neat job from a sloppy one. Use the right sized back box, ensure cables are terminated correctly, and label your runs so you know which socket links to which patch or switch. If in doubt, call an electrician — it’s quick peace of mind.
Ethernet termination follows a colour code (T568A or T568B). Mix codes and you’ll create crossovers or find sockets that don’t talk to each other properly. Most installs use T568B for consistency with existing equipment, but the key is to be consistent across both ends of the cable.
After termination, test each connection with a cable tester to confirm continuity and proper pairing. Good testers can also measure length and check for shorts. Testing prevents hours of troubleshooting later when a device “mysteriously” won’t connect.
Location matters. Place data jacks near desks, media centres, and TV units where wired devices live. For Wi‑Fi extenders and Access Points, central placement is better, but hardwired backhaul to an access point gives the best performance. Try to keep data cables away from mains wiring to reduce interference.
In living rooms, plan one or two coax and Ethernet points near the TV area plus a spare Ethernet near the media cabinet. In home offices, consider a dedicated Ethernet run to the desk and an extra port for a VoIP phone or printer. It’s cheaper to add a spare run now than drill and chase walls later.
Standard practice is to mount faceplates at a comfortable height for appliances and desks. In entertainment areas, placing plates lower behind cabinets keeps leads tidy. For offices, a desk height outlet avoids trailing cables across the floor.
The market has plenty of well‑designed modules. Click Deco ranges include coaxial and telephone modules in decorative finishes, while Varilight makes multimedia HDMI and TV outlet modules for custom media walls. Hamilton G2 modules are popular for trade installs, offering robust inserts for Cat5e/Cat6 and telephone sockets. These modules come in different master/secondary and isolated/non‑isolated options, so choose based on your technical needs.
Isolated coaxial sockets help reduce ground loop noise, which can show up as picture or hum problems on AV systems. If you have a mixed system with satellite or older amplifiers, an isolated outlet can make a noticeable difference to signal quality.
HDMI and keystone grids let you hide cables behind the wall and run a clean install to your TV. Varilight and other brands offer plates that mix HDMI with USB or RJ45, so your media cabinet remains neat and cables don’t stretch across the room.
Good wiring and quality faceplates pay off over time. While cheap faceplates might save a few pounds up front, higher quality products last longer and look better. Many reputable brands offer warranties or support, so factor that into your decision. If you’re unsure about future needs, add extra modules now to avoid more invasive work later.
If you’re installing in a high‑use area like a home office or media room, upgrading to Cat6 rated modules or premium metal faceplates makes sense. The cost difference is often small compared to the convenience of a future‑proofed setup.
Consider smart hubs and PoE (Power over Ethernet) devices when planning. If you intend to use PoE cameras or access points, ensure your switch and cabling support it and that jacks and connectors are rated for the job.
Ready to buy? Make a checklist: identify how many ports you need, which cable category you’ve used, the finish you want, and whether you need isolated or master sockets. Compare specialist suppliers like Expert Electrical for brand ranges and mainstream retailers for convenience. Always check return and warranty terms before purchasing.
Not all brands use the same module format. If you want the look of a particular range, buy matching modules and faceplates from the same manufacturer to ensure a seamless fit and consistent screw positions.
If you have several rooms to wire, buying packs of modules can save money and time. For one‑off replacements, single modules allow you to match existing styles without overspending.
Phone and data jacks are a small part of your home but one with outsized impact. With the right choices — the proper cable, compatible modules, and a neat installation — you get a reliable network that handles today’s demands and tomorrow’s upgrades. Spend time planning, pick trusted brands like Click, Varilight, and Hamilton for the technical pieces, and buy from reliable UK outlets, whether that’s an online specialist or your local trade supplier.
Upgrading or installing phone and data jacks is a smart home investment that combines practicality with aesthetics. From choosing the right RJ45 outlet to selecting a stylish faceplate that matches your decor, thoughtful decisions now will save headaches later. Use quality materials, plan for future needs, and don’t be afraid to ask for professional help when needed — your wired connections will reward you with speed, stability, and fewer interruptions.
