I am renovating my house and there is currently a BT master socket in the office with the router attached. It runs back to the access point in the hallway. The wire between the access point and the Openreach master socket is manky as hell due to replastering and other things so I want to replace it. What do I need to buy?

If you don't know what it's called the chances of success on the finished job could well be small so the simple way is to measure the distance and get an extension cable from B&Q or the likes that has matching plugs at both ends, put it under carpet, floorboards, skirting etc.

You will be getting fibre in your home at some point and after that it all becomes wireless

What do you mean by Access Point ? Just where the wire accesses your building or is there a box there that you can access ?

The BT Master socket is normally the point where the BT wire terminates .. anything the exchange side of the master is BTs . But its not unheard of for BT to simply jumper through the original master to extend to a new master when installing broadband to get close to power.

Can you take a photo or both

The setup was fitted by BT about 8 months ago when I first bought the place as I wanted internet access while im here renovating it but not living in it.

The master socket is one of these



There is then a wire running out the side of that socket along the skirting, through the doorframe into the hall and into a blanked off socket on the wall. All i want to do is replace that wire as its covered in crap from the renovation.

BT are responsible for everything downstream of the master socket and they'll be moderately miffed if they find out you have replaced the wiring. Also it would give them a perfect cop-out for any future issues ("well sir, we can't vouch for the wires that you installed"). So technically speaking you would need to get them in to do this and I can't imagine they'll be terribly bothered it if still works and you just want to make it look a bit nicer.

That said it is moderately unusual for the master socket not to be located at the point that the cable enters your property so are you 100% sure that is what you've got?

Edit: ignore second comment above, just seen the subsequent post. That sounds like a bit of a bodge job by BT to be fair. It's not a hard job to rewire a socket but you will need the right tools. If it's still working but covered in plaster then I'd be tempted to either cover it in some trunking or spend a few minutes giving it a good clean.

It looks like the blanking plate in the hall is where the master socket should be and they have just run a cable from there to where they fitted it in the office room. I’m currently replacing the skirting in the office after replastering, haven’t done the hall yet, and just wanted to neaten it up.



Looks like the wire is this stuff would that be right?

Open up the blanking plate - and make sure that there is a termination block there ( the block you punch the wires into ) and its not just the dropwire that has been extended ( unlikely but worth checking )

The wire you've linked to would work , but if you have any spare ethernet cable that would work as well ( though you have a few extra wires)

As mentioned by someone else - BT don't like it as its supposed to be their wires to the master socket , BUT i've seen BT techs do it when there is no power near the master socket.

More likely to be an underground feed terminating directly onto the back of the nte , very unlikely there will be a block terminal in the patress box , just extend the wires to wherever you need them , wago connectors will work if you can’t get hold of some proper telecomm type crimps .personally i would run a length of cat5 rather than that budget phone cable from screwfix .

Whip the cover off the blanking plate & take a picture so we can see the join but the cable BT use is nothing special really. CAT5e will do very well, otherwise there's plenty on ebay - either 4 core or the later 6 core:

Just remember the analogue phone system is being turned off in a couple of years time so you'll need a termination near a power point if you want a BT line. It might be another reason to run CAT5e in. Leave a bit of a spare loop in the wall plate.

Yes cat5 is fine , lots of builders have been using cat5 for years now between the bt feed and the nte5 .

The proper specced stuff is CW1308 but as mentioned above, a length of cat5 would work just as well (and is probably higher spec)
