Analogue television in the United Kingdom
Analogue terrestrial television in the United Kingdom was, traditionally, the method most people in the UK, Channel Islands and the Isle of Man used to receive television. It was phased out and replaced by digital terrestrial television between 2007 and 2012 on a region-by-region basis. Before the switchover, some people struggled to receive the digital transmissions as power levels were very low from some transmitters.
Initially, satellite systems broadcast using standard (PAL) signals though often scrambled to prevent people watching the channels without paying a subscription.
The major provider of satellite television in the UK, BSkyB, launched a digital service (called Sky Digital) in October 1998 based on DVB-S. This allowed many more channels and was marketed with a smaller dish. Take-up was very quick and successful, and Sky discontinued the former analogue service in June 2001 - just three years after digital satellite was launched. Although some of the channels which had been part of their package, such as CNN and CNBC Europe, have continued broadcasting unaffected by Sky's departure.
It was originally planned for the analogue switch-off to occur on 31 December 2002, but this was achieved 15 months earlier. The last three channels, Sky Premier, Sky One and Sky Sports 2, were switched off at 00:01 on September 28, 2001. Sky analogue equipment could still pick up German channels until 30 April 2012 when they were shut down.
Cable also broadcasts using standard (PAL) signals though often scrambled to prevent people watching the channels without paying a subscription.
Cable has not fully transitioned to the digital format (DVB-C) as some parts of the physical cable network are not suitable for transmitting the digital signals. As a result, analogue cable television is still active in some parts of the country, only in ex-NTL areas (most notably Milton Keynes), as ex-Telewest areas have all switched off in January 2012.
Before any area had analogue TV switched off, all analogue TV customers in the area received a letter from Virgin Media offering a free switch to their digital TV service. If the customer chose not to migrate to digital, they would've lost all TV channels when the switch off occurs.
Customers with the cable feed plugged directly into their TV or have an RF bypass installed, which allows them to watch the analogue terrestrial channels independent of their set-top box, will also cease to receive channels when the analogue signal is switched off. Customers will still be able to receive channels via their digital set-top box. In some parts of the network where digital cable is available, analogue transmissions have been ceased in order that the bandwidth may be utilised for more data for the digital platform, in others both systems run alongside each other, though often new channels will launch on digital at the expense of channels on the older analogue network, which encourages those users to switch.
A TV that is capable of tuning frequencies used for cable is required for watching, plus note that no channels are receivable in Ex-Telewest areas as Virgin Media have stopped their analog television in these areas.
Milton Keynes 
In Milton Keynes, there has been a cable network ownership dispute between BT and Virgin Media for a decade. Milton Keynes was designated as a new town in 1967 and benefited by having the UK's first ever analogue cable television networks, owned by BT. In the 1990s, EU competition forced BT to sell/lease the service to NTL (later becoming Virgin Media). Since then, BT and Virgin have been unable to reach agreement on physical access, and as a result, Virgin Media are unable to offer digital cable TV in Milton Keynes.
Even worse, Milton Keynes is built in dip (surrounded by high terrain and trees), and as a result, most residents are also unable to use Freeview terrestrial or even Sky and Freesat satellite signals.
As of 2009 in Milton Keynes, there are about 35 channels available on the analogue cable network, of which 18 are free-to-air. All residents pay at least £4 monthly for TV, which includes the following channels: BBC News, British Eurosport, Cartoon Network, CNBC, CNN, Discovery Channel, Discovery Home & Leisure, Universal Channel, Movies 24, MTV, Film4, QVC and Yesterday. There are four optional add-on packs, which include channels: Challenge, Gold, Nickelodeon, VH1, Sky Living, Sky1, Comedy Central, TCM, Syfy, The History Channel, National Geographic and Sky News, which range from £5 to £13 extra per month.
Westminster in London had the same problem, where BT owned the cables. Residents are also unable to install satellite dishes due to constraints. BT's cables have insufficient bandwidth, so Virgin are unable to provide fibre optic services there, which in turn means no digital cable TV. For years, residents were waiting for digital cable TV to come, but finally on 8 August 2011, Virgin Media withdrew all its services in Westminster, including its analogue TV service. It was closed completely in January 2012. Now with satellite not allowed in the district and IPTV unable to get signals, the only option left is terrestrial television, like Freeview.
BBC One and BBC Two 
BBC One and BBC Two can be picked up by any television in the UK. But some areas have reported they cannot receive it. There have been no problems with the channels theirselfs. The BBC say they have been broadcasting the channels since the 1930's and they don't think anything should go wrong with their channel.
