The perfect world answer is no . You must contact your service provider who will arrange for a BT Openreach engineer to do the work at their outrageous hourly rate.
BUT in reality most service providers will tell you to get an electrician to do the work - but BT count this as trespass and it is illegal. However you can't contact BT Openreach directly as they wont talk to end users so back to your service provider you go. Who will tell you to contact BT Openreach ....etcetera etcetera etcetera .
BT do not keep a record of where your main socket is and would never visit your property unless you ask them to , so , if an electrician where to do the work for you , as long as he didn't mess it up and did it to the same quality standard as BT they would never know the difference and if any one asked which they wouldn't, " It was like that when I moved in guv ". The job is almost as easy as putting in an extra socket and requires no specific mandatory qualification unlike a gas fitter would legally be required to be Corgi registered to work on gas.
Is BT trespassing on your wiring when BT remove your face plate / extension wiring to test ?
If you haven’t changed your service provider for a while ( 2 years ) you will probably notice your bill rising.
You could save money by switching your Service Provider but this is a lot of hassle. An easier way to go about it is to call your them and threaten to change S P unless your bills are reduced .
They will do anything to keep your direct debit going . As long as they can keep helping them selves to your money they will. Even if it means putting you on the latest cheapest deal.
Don’t assume switching back to "good old BT" is going to be any better, they are one of the worst for upping your bill every year.
I met an old dear living alone who was paying BT £475 / year for phone and BB and a load of other stuff she didn’t know anything about. You should be able to get both for £260 / year. Beware low (10gig) data limits this fine if you are an old dear living alone but not for the techno family watching you tube every night.
Why you cant lag to far behind the tech times !
Your steam engine works perfectly but all the railways have been replaced by maglev mono rails !
Your 7 year old PC works perfectly unfortunately your wifi card is wireless 802.11b and the router you have just been sent is only compatible with 802.11g and 802.11n so the wifi doesn't work. Also it runs on windows XP but windows XP will not be supported since april 2014. So you need a to update your operating system. Windows 8 :- cost £70 ,and wont run on your steam train.
