Judith: If the TV has a "region" or "network" setting in the menu then this is one way to prefer the NW one to the Wales one. I think this is generally only newer receivers, particularly HD ones.
Manual tuning to Winter Hill, assuming this is the NW transmitter your aerial is directed to, might be the only easy way of achieving correct tuning. The problem is that it's likely tuned to Moel-y-Parc transmitter in North Wales -- this is an assumption on my part as without knowledge of your exact location it isn't possible to know exactly but this is generally a common issue in the NW.
Or unplug the aerial during the scan up until UHF channel 46 / 50%. This is tricky, isn't forced to work, may require additional work to get the exact timing right or may leave some channels out which means addiational scans ("add new services" or similar ideally).

Mick Bennett: Interference from a nearby appliance sounds the likely cause. Did the time of the interference change when the clocks changed? (i.e. was it 20:45 GMT on Saturday and 20:45 BST (19:45 GMT) on Sunday)

David Hewitt: There's no work indicated as taking place at Winter Hill this week. You could give at800 a call to see if the issue coincides with a new 800MHz 4G base station coming on air. Channel 59 is closest of all Winter Hill's to the 800MHz band which is C61 upwards.
With reference to resetting and retuning, Einstein said "Insanity is doing the same thing over and over again and expecting different results". If the box is tuned correctly -- i.e. to the right frequencies and therefore correct transmitter -- then it will give you the best picture for the signal being fed into it.

MikeB: David Hewitt says he lives near Chester, so isn't likely to have an issue with too high a signal level from Winter Hill.

Tim Newberry: The most common answer to such a question is that the receiver being used is not a Freeview HD (DVB-T2) one. What's the make and model of the device?

MikeP: 0333 numbers, as with all numbers beginning 03, are geographic rate. This means they are included in packages just as geographic (01/02) calls are and cost the same when otherwise called outside the terms of a plan. This applies to landlines and mobiles. It's possible that overseas providers charge more to call UK 03 numbers (+443) than geographic ones (+441 and +442).
Freephone numbers begin 0800 and 0808. There are also a few in the 0500 range and these will be phased out.

Stuart: Yes.
Unfortunately "common sense" with respect to all multiplexes going vertical has not prevailed. Thus, vertical polarisation is only best where reception of COM4 to 6 is not good and where COM7 (and 8 in the future) is to be forfeited or is otherwise not good anyway.

David Cooke: Enter a different postcode. The postcode is purely so as to give you the appropriate regional output.

B. Vernon: Knowledge of your location, preferably in form of postcode or that of a nearby property such as a shop or post office, is really required. However, it may be that it's not so much your distance from the transmitter, but that you don't have line-of-sight, this being possible to check for one knowing the location.
What I will say is that if you're hoping to pick up the quasi-national COM7 (and future COM8) multiplexes -- these carry BBC Four HD, BBC News HD, 4seven HD and others -- then you "might" need a different aerial, if indeed you will be able to receive the lower-power signal from Winter Hill.
