The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Which companies have run the Channel 3 services in the Sudbury transmitter area
DigitalUK's postcode checker - using the detailed view - is generally quite accurate and it's predictions are based on a 100m square for a given postcode (the number of houses covered by a postcode will vary from postcode to postcode). Looking at the local terrain using the tool available on this site, Paul Dicken's postcode has a very local hill between him and the Woodbridge repeater which is why prediction for that is very poor to non-existent reception, whereas there is line of sight to Sudbury.
Without looking at an OS map (for which I don't have time) I don't know how many hills there are in that area but as I'm sure you know, "high gain" aerials and stacked arrays were often used in analogue days to reduce or eliminate ghosting due to there greater directivity etc. I had precisely that problem where I used to live, whereas now with the digital signals a simple yagi does the job fine. In that particuler area a lot of houses are using a local repeater (with only the 6 + local muxes) whereas others use the main transmitter (all muxes) as digital reception is fine. Hence looking at (newish shiney - not old) immediately local aerials can only be used a rough guide to reception.
At Paul Dicken's postcode, if most of the new very local aerials are high gain, I'd probably consider the Yagi as the 3 PSB muxes at on UHF 41,44,47 although a Log36 will do a better job of rejecting impulse interference and only has slightly lower gain over the band.
As regards reception changes next year, if you look on DigitalUK at all the transmitters that are listed to change channels during April to June, you will find the information.

You are just 7 km from the transmitter so are likely to be getting a very strong signal, perhaps too strong. So start by checking the indicated signal strengths on all the multiplexes. They need to be between 60% and 85%, any more will cause significant problems that can be cured by fitting an attenutator into the aerial cable behind the set, using a new flylead to prevent the weight from 'hanging' on the aerial input socket.
You should also check that you are tuned to the correct channels. Put your full post code and house number into the Digital UK Coverage Checker at Digital UK - Coverage checker and scroll down to find the Sudbury transmitter details in the listing. That will give you all the current, and future, channel numbers being used for the multiplexes.

Possibly all just a coincidence but ...
1. My freeview tv suddenly stopped working with "no signal" (two weeks ago)
2. Next door neighbour has just had a new arial because was getting interference
3. House over the road has had some arial work done.
I have sent my tv away for repair (still under guarantee) I am waiting to see what happens.
Postcode IP11 9LP (North Felixstowe)
Have there been aany changes to the transmissions? (Sudbury I think)

Rob: There are no changes reported for Sudbury in the last couple of weeks, although reception of some multiplexes aren't predicted to be the best at your location. Did you check for any loose or damaged cables or connections before sending your TV away, or did you just assume it was at fault?

The last engineering work carried out at the Sudbury transmitter was on 1st August 2018, no other work has been done since.
It is worth checking your aerial system to ensure that all the cabling is in good condition and that all joints are in good order. If there are coaxial plugs/sockets then unplug those and refit them to clear any possible corrosion/oxidation from the contact surfaces.
If you have access to another Freeview TV then use that to check that your aerial system is working correctly.
