Reconnect internet cable.

Professional internet cable reconnection ensures that signal loss is minimised and that your hardware operates at its advertised speeds. Whether you are dealing with traditional copper (FTTC) or ultra-fast full fibre (FTTP), understanding the repair process helps you avoid prolonged downtime and recurring faults.

What Does the Work Involve?

• Diagnostic Testing: Using specialist meters to locate the exact point of failure between the street cabinet and your router.
• External Inspection: Checking the "drop wire" from the telegraph pole or the underground ducting for physical wear or water ingress.
• Cable Splicing or Replacement: Stripping back damaged sections and using professional-grade crimps or fusion splicers for fibre optic links.
• Socket Servicing: Replacing the Master Socket (NTE5c) or the Optical Network Terminal (ONT) if the internal components have failed.
• Pathfinding: Re-routing cables through walls or floors if the original path is no longer viable or has been built over.
• Verification: Running a "Sync Test" to confirm the line profile is stable and performing a speed test to ensure no data packets are being lost.

Typical Costs

Pricing is primarily influenced by the type of connection (Full Fibre vs. Copper) and the physical accessibility of the cable. If a cherry picker or scaffolding is required to reach a high entry point on a gable end, costs will increase significantly.

How Long Does It Take?

• Basic Socket Replacement: 30 to 60 minutes.
• Standard Internal Reconnection: 1 to 2 hours, including testing.
• External Cable Pull (Underground): 2 to 4 hours, depending on duct clearance.
• Full Property Rewire: 4 to 8 hours for complex or large domestic properties.

DIY or Professional?

While you can legally replace internal extension wiring yourself, you must not touch the provider’s side of the Master Socket or the external network. In the UK, the "demarcation point" is usually the first socket in your home; everything before that is the property of Openreach, Virgin Media, or an AltNet provider.

Attempting to repair a fibre optic cable yourself is highly discouraged, as the glass strands are thinner than a human hair and require specialist laser-splicing tools to rejoin without signal loss.

Furthermore, DIY repairs often use "jelly crimps" or electrical tape, which can cause high resistance and "noise" on the line, leading to frequent disconnections and reduced speeds.

Choosing the Right Tradesperson

• Check Credentials: Look for ex-Openreach engineers or technicians with City & Guilds in Telecommunications.
• Specialist Tools: Ask if they carry a TDR (Time Domain Reflectometer) for copper or an OTDR for fibre to pinpoint breaks accurately.
• Insurance: Ensure they have Public Liability insurance, especially if they are drilling through walls or working at height.
• Ask: "Will you provide a printout or screenshot of the line sync speed after the repair?"
• Ask: "Is your work compliant with current BSI standards for data cabling?"
• Ask: "Does the quote include the cost of all faceplates and weather-proof external boxes?"

UK Regulations

• Ofcom Boundaries: Regulations dictate that only authorised engineers should work on the primary network infrastructure.
• Part P Compliance: While data cabling is low voltage, any work near mains electricity must follow safe separation distances to avoid interference.
• Building Regs (Part B): Cables passing through fire-rated walls must be properly fire-stopped with intumescent materials.
• Paperwork: You should receive a service report detailing the "Attainable Rate" and "Signal-to-Noise Ratio" (SNR).

Common Problems

• Bridge Taps: Old, unused extensions left connected to the main line act as antennas for interference, slowing down your broadband.
• Water Ingress: Damaged external "grey boxes" (GPO boxes) allow rain to corrode copper joints, causing crackling on lines or total drops.
• Poor Quality Cable: Using unshielded or CCA (Copper Clad Aluminium) cable instead of solid copper leads to significant data loss over distance.
• Crushed Fibres: Tight bends in fibre optic cables can cause "micro-bends" that leak light, resulting in a total loss of connection.
