Title: UK system has multiple formats.

Comment:
Most UK telephone numbers can have either 9 or 10 digits after the 0 trunk prefix. The initial 0 is omitted when calling from abroad.
01 and 02 area codes should have parentheses around them if the local number part does not begin with a 0 or 1. 01 and 02 area codes do not have parentheses around them if the local number part begins with a 0 or 1. These are National Dialling Only ranges.
All other area codes do not have parentheses around them as the area code is required for all calls. Number formats are expressed as:
2+8 to represent (02x) xxxx xxxx [in 5 areas] or 05x xxxx xxxx or 070 xxxx xxxx or 076 xxxx xxxx.
3+7 to represent (011x) xxx xxxx [in 6 areas] or (01x1) xxx xxxx [in 6 areas] or 03xx xxx xxxx or 08xx xxx xxxx or 0800 xxx xxxx or 09xx xxx xxxx.
3+6 to represent 0500 xxxxxx or 0800 xxxxxx.
4+6 to represent (01xxx) xxxxxx [in 580 areas] or 07xxx xxxxxx.
4+5 to represent (01xxx) xxxxx [in 41 areas].
5+5 to represent (01xx xx) xxxxx [in 12 areas].
5+4 to represent (01xx xx) xxxx [in 1 area].
Valid formats include:
(011x) - 3+7.
(01x1) - 3+7.
(01xxx) - 4+6 or 4+5.
(01xx xx) - 5+5 or 5+4.
(02x) - 2+8.
03xx - 3+7.
05x - 2+8.
0500 - 3+6.
07xxx - 4+6.
070 - 2+8.
076 - 2+8.
08xx - 3+7.
0800 - 3+7 or 3+6.
09xx - 3+7.
There are a small number of exceptions such as 0800 1111 and 0845 4647.
The UK system is quite complex!

Comment:
5-4-2 is not a valid UK format, certainly not for 0800 numbers (which you have shown in the examples as 4-4-2 and this is also not a valid format).
