How to Troubleshoot and Report a Line Fault
If there's a problem with your telephone service then you'll need to report it to us either by calling us or through Contact Us.
1. Before you contact us
Before you do anything else, run through the checks listed below. There's a few things you'll need to look at so to make things easy we've split the checks into two sections:
- Basic Checks - check everything mentioned here, whatever problem you're having
- How to report a telephone fault - if you're still having problems, find out how to report them
Why do I need to do all this?
If we raise a fault to our suppliers and they find that it's caused by your equipment or wiring then you'll be charged for the callout and repair time. Obviously we don't want that to happen! Charges may also apply in cases with damaged external wiring - e.g. the wire from the telegraph pole to your building, or any underground cabling within your property boundaries.
There'll be no charge if the fault lies with the line outside your property or in the Telephone Exchange.
Callout and repair time charges will apply if the fault lies with your equipment or internal wiring.
Why isn't my broadband working?
Broadband is supplied over your telephone line, so it needs the line to be working properly. Subsequently, it's very common for telephone faults to cause problems with broadband service. You may see slow speeds or you might not be able to connect at all.
In nearly all cases, once the telephone line is fixed the broadband will be too. Connection problems tend to clear up immediately, with slow speeds it'll be a few days before your speed gets back to normal.
2. Basic Checks for ALL telephone faults
Are you using a cordless phone?
- Make sure it's fully charged, a low battery can cause more problems than you'd think!
- Do you still get the problem if you connect a standard corded phone? If not you'll need to speak to the manufacturer of your cordless phone
Check your microfilters and broadband setup
- All equipment connected to your line needs to pass through a microfilter - see our Fitting Microfilters Guide for help with this
Check the master socket
The master socket should be installed at the point where the telephone line enters your property.
Unplug everything from your line (including broadband, TV equipment and all microfilters) and connect a working corded telephone to the master socket. Is the problem still apparent?
- If this fixes the problem: Either your extension wiring or something connected to your line is causing the problem. Find out which by checking after plugging each piece of equipment back in. Try replacing your microfilter(s) if you can't find the culprit

Problems making calls
- Try dialling with 1280 as a prefix (e.g. 1280 0844 395 0830), this will force to call to be made over our network. If you're able to make calls using the 1280 prefix then you'll need to speak to your call plan provider.
- Do you have the same problem with all your telephones? If only one of them is affected, it’s probably a fault with that connection or handset.

- If you're still having problems, report the fault by calling us on 0844 395 0830

- If you're told that Identities will be displayed: Try another corded caller display phone on the line
