Install a TV point.

While many modern TVs rely on Wi-Fi, a hardwired coaxial or Ethernet point remains the gold standard for stability. This guide covers everything from signal testing to the latest 2025/26 pricing for professional TV point installation across the UK.

What Does the Work Involve?

• Signal Strength Assessment: Using a digital signal meter to check the decibel (dB) levels from your existing aerial or satellite dish.
• Route Planning: Identifying the most discreet path for cabling, whether through loft spaces, under floorboards, or via external walls.
• Cable Installation: Running high-quality, double-shielded coaxial cable (typically RG6 or CT100) from the splitter to the new location.
• Faceplate Fitting: Installing a recessed or surface-mounted back box and a high-quality shielded faceplate.
• Termination and Testing: Stripping and crimping connectors correctly to prevent signal leakage and testing the final output at the socket.

Typical Costs

The cost of installing a TV point depends largely on the distance from the existing splitter and the complexity of the cable run. Internal "stud wall" runs are generally cheaper than drilling through solid Victorian brickwork.

Pro Tip: If you are having a TV point installed, consider running a Cat6 Ethernet cable alongside it. This "future-proofs" your setup for 4K streaming and smart TV features that often struggle with weak Wi-Fi signals.

How Long Does It Take?

• Simple internal run: 1–2 hours. This usually involves a loft-to-bedroom drop or a short run through a stud wall.
• External cable run: 2–3 hours. Routing cable around the exterior of the house and drilling through masonry takes longer to secure and weather-seal.
• Multi-room installation: 4–6 hours. Setting up a distribution amplifier and running cables to multiple rooms across different floors.

DIY or Professional?

While you can buy a DIY "Y-splitter" and a roll of cable at a local hardware store, the results are often disappointing. Every time you split a signal, you lose power; without a professional signal meter, you won't know if you need a passive splitter or a powered masthead amplifier.

Professional installers use double-shielded cable to prevent "ghosting" and interference from 4G/5G mobile towers. Furthermore, working at height to access aerials or satellite dishes carries significant risk and requires specific insurance and safety equipment.

Choosing the Right Tradesperson

• Check Qualifications: Look for members of the CAI (Confederation of Aerial Industries). They are vetted and must adhere to strict codes of practice.
• Ask about "Benchmarked" Cable: Ensure they use CAI-benchmarked coaxial cable, which is designed to handle modern digital signals without interference.
• Red Flags: Be wary of installers who don't use a signal meter or those who suggest "taping" cables to the outside of drainpipes, which can lead to water ingress.

• "Will you be using a digital signal meter to verify the dB levels at the new point?"
• "Is the cable 4G/5G shielded to prevent interference from mobile masts?"
• "Do you provide a guarantee on both the parts and the signal quality?"

UK Regulations

• Part P Building Regulations: While standard coaxial cabling is low voltage and doesn't fall under Part P, any integrated power sockets installed alongside the TV point must be fitted by a competent person.
• Working at Height: Installers must comply with the Work at Height Regulations 2005. Ensure your pro has public liability insurance that specifically covers "working at height."
• Listed Buildings: If you live in a listed building or a conservation area, there may be restrictions on where you can mount dishes or run external cabling.

Common Problems

• Signal Degradation: Using cheap, unshielded cable or poor-quality splitters leads to "pixelation" or total signal loss on certain channels.
• Water Ingress: If an external cable isn't fitted with a "drip loop" before entering the wall, rainwater can run down the cable and into your home or TV.
• Interference: Unshielded cables picking up noise from LED light transformers or nearby mobile phone towers.
• Poor Termination: Loose F-connectors or stray braids touching the centre copper core, causing a short circuit in the signal.
