Fit a 6db attenuator onto the aerial cable, in the loft, just before it goes into the 4 way amplifier. You can get one of these from Maplins, or buy from the internet. You'll need to go into the loft and disconnect the aerial cable (from outside aerial) from the 4 way amplifier to see what kind of connector it has. You'll need to buy an attenuator with this same connection type. It's either going to be F type (screws on) or the usual Belling Lee (normal coax plug pushes in).

If it's not the amplifier being overloaded then it's going to be RF inteference and I'd be a bit worried about what this is doing to the BER (Bit Error Rate) of the digital muxes.

If you're worried about the analogue signals then you might want to get them back to sort it out, but if you've got Freeview everywhere then it's not as much of an issue assuming the Freeview signals have been measured correctly and are robust.
