Telephone extensions and phone line faults.
A phone socket in another room, a crackly line that no one can pin down, or old extension wiring to make sense of after the move to digital phone lines. We sort telecoms wiring for homes and businesses around Chichester.
5.0from 130 Google reviewsWhere your phone line becomes your wiring
Your phone line comes into the house at the master socket, usually near the front door or in the front room. Everything up to and including that socket belongs to Openreach. Everything after it, the extensions running to other rooms, is your own wiring.
That split matters when something goes wrong. If the fault is in the line outside, it’s your provider’s job to fix. If it’s in the extension wiring inside, they’ll often charge to come out, and that’s where we come in.
We add new extension sockets, tidy up old ones, and find faults in internal phone wiring. Moving the master socket itself is a job for Openreach, but we can extend from it to wherever you need a line.
Telecoms jobs we take on
Small jobs that are a pain to sort yourself.
New extension sockets
A phone point in the office, bedroom or extension, run neatly from the existing wiring rather than a long cable along the skirting.
Fault finding
Crackling, a dead socket, a line that drops calls or slows the broadband. We test the internal wiring and find the problem.
Tidying old wiring
Years of add-ons, dead sockets and cable that goes nowhere. We take out what isn’t needed and leave what is working properly.
Businesses
Extra sockets and tidy telecoms cabling for offices, shops and premises, often alongside network cabling.
The switch to digital, and your extensions
The old analogue phone network is being switched off across the UK, and landlines are moving to digital.

On a digital line your home phone plugs into the broadband router instead of the wall socket. Calls travel over the broadband connection.
What it means for extensions
Extension sockets wired from the master socket may stop carrying calls once the line goes digital, because the phone signal now starts at the router.
Your options
Depending on the house, the existing extension wiring can sometimes be fed from the router, or cordless handsets around the house may be simpler. We’ll look at what you’ve got and tell you which makes sense.
Things that use the phone line
Some alarms, telecare pendants and older payment terminals rely on a phone line. Check with their provider that they’ll work on a digital line.
A quick test for a faulty line
On most modern master sockets the lower half of the faceplate unscrews to reveal a test socket. Plug a phone, or your router, straight into the test socket. If the fault disappears, the problem is in the extension wiring inside the house, and that’s something we can fix. If it’s still there, the fault is on the line, so report it to your provider.
Not comfortable taking the faceplate off, or not sure what you’re looking at? Give us a call and we’ll talk you through it or come and test it.

"As I am a widowed older person I was cautious in contacting Cox AV to look at my TV and aerial. I needn’t have worried. He was quick, his work good… I would not hesitate to recommend him. Thank you Lee."
