pete: No. The UK now has a two-tier terrestrial transmitter network. This is because there are two types of broadcaster.
The Public Service Broadcaster (PSB) channels transmit from the Weymouth relay. There are over 1,000 other low power transmitters which serve about 8.5% of the population which also only carry PSB channels.
As well as Public Service Broadcasters, there are now Commercial broadcasters (COMs) which have no obligation to provide a "Public Service", only make profit. For this reason they only broadcast from the largest transmitting stations and are therefore not "missing" from any transmitting station as it is their choice as to which they serve from.
For a further explanation, see:
Londonderry (Northern Ireland) digital TV transmitter | ukfree.tv - 10 years of independent, free digital TV advice
It is doubtful that you may be able to receive the full service (from another transmitter). As well as having inferior coverage due to not being carried from all stations, there are some who can only receive PSB stations reliably even though they are using a full-service transmitter. This is because the signals aren't as good as well as the frequencies they use being reused by transmitters in closer proximity than the PSB frequencies are reused.
The COM channels from Stockland Hill share frequencies with the COM channels of Rowridge, so at your location you "may" find that this rules out reception of the full service from the latter. That said, Rowridge's channels are vertically polarised and Stockland's are horizontally polarised.
See if any of your neighbours have aerials directed to Rowridge which is on a bearing of 84 degrees. Rowridge broadcasts horizontally and vertically now, albeit that the COM channels are better with the latter. The fact that someone has an aerial pointing to it does not necessarily mean that they can pick up all channels.
You may give consideration to Freesat, particularly if you are unable to receive the Freeview COM channels.

Last night our freeview services went off the air. This morning Freesat is broadcasting OK. Where can I find out if there is transmitter maintenance being carried out? Thanks for reading.

Forgot to mention our aerial is in the roof and we are using Chatton transmitter,

Edwina Waters: Nothing has been indicated as yet on the transmitter fault reporting site nor is any engineering work taking place, although in cases like this its always best policy to check with a neighbour just to make sure that the problem is not being caused by some glitch having occurred within your own installation.
By the way, you can check these two sites by clicking on "R+T Investigation" seen on the list of four choices on the right hand side of your posting, and with planned engineering works being accessed by clicking on "Digital UK tradeview" and then by placing your pointer on "Help and advice" you will see planned engineering work on the bottom of the drop down choices

Response with thanks to Dave Lindsay and jb38
I will look at the aerial next time I visit my relations and see if its both level and turned to either vertical or horizontal and in view of Dave's observations whether it is high enough, i.e. pole or bracket mounted? I was amazed at how regular the disruption was though bearing in mind location it was almost as if some nearby military or private system was being switched on for a period just like a scan sequence. Thanks anyway.

Hello everyone
For the last 5 week my freeview picture has been breaking up and freezing
it seems to start at 4.20 in the afternoon and stops at roughly 10.20 in the evening a friend in the same street is having the same problem
we thought aerial but that's been checked and is fine
I live in Northampton NN3 8PW and its been fine up until now The aerial is on the roof using Sandy Health transmitter
we have been told its interference from an outside source but what and how do we find out where
Any help would be very welcome Thanks

Becky: I would use a AM (MW or LW) radio powered from batteries. Tune it away from a station and listen for any noise. Have it on at the start and end time and see if the start and end of the noise on the radio coincides with the TV signal breaking up, that way you know you are listening to the cause.
AM radios have a ferrite rod in which act as the antenna. They are most sensitive in the axis perpendicular to their length. Hence, if you hold the radio with it facing you, when the sound is the loudest you know that it is coming from in front of, behind, above, or below you (or somewhere on that axis). Spin round to where it is at its quietest and the source of the noise must be from either end of the radio.

Hi JB38,
Thanks for the information. I found the cause of the problem - I must have accidentally pressed a button on the TV remote and found that it was not actually connected to the freeview box. My fault and I feel a bit sheepish now, but thanks again anyway!

Edwina Waters: Many thanks for taking the time to give an update on the situation, the main point being that everything is now OK again.
