Maldon
my reception seems alright during day and starts breaking up late evening, l am wondering if there is some sort of work being done, but on checking it states everything is good.
my postcode is CM9 6GE flat 7,Maldon Essex.
could you confirm if this is the case.

There doesn't seem to be any reported faults that I can find, nor is Sudbury listed for Planned Engineering at present, however there are weather conditions that may affect some signals for some at this time, but if this is a regular problem rather than one that's just occurred that's probably not the case.
Which channels are you noticing the problems with?
Your location is predicted to have possible variable reception for the SDN/COM4 & ArqA/COM5 multiplexes.
See https://www.freeview.co.uk/corporate/platform-management/channel-listings-industry-professionals for TV channels are carried on which multiplexes.
It may be worth checking in your TV tuning section that you are correctly tuned to Sudbury's UHF channels as more than one transmitter could be picked up at your location.
The correct UHF channels are as listed at the top of the page.
If your tuning is all correct, it would be worth checking with your neighbours (as you are most likely on a communal system in a block of flats) to see if they have the same problems. Even if they don't it might be a good idea to speak to the management about getting your connection checked out, or the whole installation if neighbours have the same problem.

We live in Howe Green Chelmsford and have had no picture on two of our Freeview T Vs for some time. I was told it was because the Sudbury mast was being repaired, I have tried several times to retune it without success. Our Sky TV is fine. Is there any way this can be rectified? Many thanks, James Knights

James Knights: I can't see any engineering work listed for Sudbury and although you are 38km away you are predicted to receive a strong signal on all multiplexes. Are both TVs connected to the same aerial? If so, is there either a powered amplifier or passive splitter to split the cable? As a starting point, it would be worth checking all the cables and connections as far as you can safely access and also check that the amplifier is powered on if there is one.

Chris SE,
I note your comment that certain areas may hage problems with SOME multiplexes. Why so? Surely if they have problems it will be with ALL multiplexes.

IfI get problems, they are worst with the multiplex using channel 37. Why?

It all depends on weather conditions, lay of the land, line-of-sight to various transmitters, whether the signals pass over largish areas of water etc. and which transmitters are co-channel.
RF propagation is very frequency dependent and also on the nature of the atmosphere at the particular time as well as the extent of any area with particular conditions, so one specific UHF channel may get propagated differently from another.
As you've never given a full postcode or one for a very nearby pub/shop/prominent building your predicted reception for C37 may be poorer than some of the others.
Your aerial may have a peaky response which is not as good for C37 as it might be for others (whether it's home brew or bought!). So all in all, difficult to know why, or indeed where particular interference may come from most of the time.
Whenever I glance at Dx reception reports from people on the east coast I don't recall C37 being mentioned, C39 is quite common. Trying to find out which Netherlands or other countries transmitters that side of the North Sea use particular channels is almost impossible as I can't readily find reliable sources.

Chris SE,
Thanks. IP15 5HG
Signal on all multiplexes is good, but 37 is the one that goes first. This is using any aerial,and odd because it is not at the exteme ends but nicely in the middle.
We don't use 39!
You seem to be suggesting the Dutch, my thought too.
Can you tell me where to look for the DATE we send our messages? Just seeing the time they are sent is no use!
