Ipswich can get interference from continental tv stations but if the problem is recent I suspect a problem with your aerial or its connections or plugs. (possibly a source of interference such as a new phone mast may be the culprit. But your aerial system being faulty is more likely .)
Your area is a bit complicated for best reception. See the digital coverage checker as Mike suggests. You could get rock solid basic BBC and ITV channels with a small possibly loft aerial (vertical polarisation) from the Ipswich relay transmitter . the other channels probably need a good outdoor aerial for Sudbury . Idealy one with low pick up to the east (rejects continental signals ) A few channels (that you might want ) are better from dover . But having two or three aerials is probably for experimenters and enthusiasts !

There are currently no changes for Sudbury next year. It's changes at other transmitters (which is why you'd need to look through DigitalUK) that will affect reception of signals from Sudbury at certain locations in Sudbury's reception area.

Thanks for all your responses. I have now had the TV back from the repairers. I don't know if they actually did anything, but it worked fine for a few days and now (18.30 on Wed 24th Oct) it has suddenly started (intermittently) doing the same. I have a high gain external arial and a 4 way booster/splitter in my loft. The other TVs in my house are working fine and I have tried switching them around. It seems that perhaps this particular TV has a weak RF/tuner stage?

Please can you check what the signal strength is as repoirted by that TV set. You can usually find that on the manual tuning option - but do not retune.
Some sets have rather sensitive tuners that do not respond well to too strong a signal, so the usual advice is to aim for no more than 85% strengths on all the multiplexes. Other makes may have a less sensitive tuner so are less affected by too much signal.

Rob . because you can receive several transmitters it might be that particular tv could have trouble selecting the right frequency for a given channel. Maybe not so likely with a modern tv . But to check I would use the tuning menu to verify that the set is tuned to the correct UHF channels (not freeview channels).

I agree with Mike that too much signal for a sensitive set is a possibility . Perhaps one way to temporarily test on a lower signal is to connect the aerial without the amplifier.

We currently have no freeview signal from the Sudbury transmitter. It went off at about 8.15 this morning. Freesat signal not affected.

Colin Berwick: There are no faults showing for Sudbury. Have you checked for any loose or damaged cables or connections behind your TV? Do not attempt to retune.

In CM7 - we seem to have lost all reception on C47 (682.0MHz), so we no longer have access to any of the HD channels that we could before. We have great reception on all others though, so is this a transmitter thing or an issue to look into at the receiver end?

We need a full post code , not a partial, so that we can look up the expected reception conditions at your location. (A partial such as you have given covers several dozens of square miles and is insufficient to trigger the information needed.)
It is extremely unlikely to be the transmitter, no one else has reported any problems, so I suggest you carefully check all the aerial cables and connections. Unplug all coaxial plugs and sockets and then refit, that will clear any corrosion/oxidation from the contacts which is a common cause of the problems you report.
Then check what the signal strength is reported to be on all the multiplexes broadcast from your local transmitter. You ideally need it to be between 60% and 85% on all multiplexes to have sufficient to allow the TV to decode and not so much as to overload the tuner.
