What also is not helping the situation is
some Commanders insistence on 2 stage de icing and anti icing even though the weather conditions/hold over times don't require it.
I do agree though that it is about time that LHR looked at having remote de-icing on a more permanent basis - although this would then possibly lead to a monopoly on the de-icing as only 1 company would be able to do it, rather than several as is the case at the moment.
