Is the provision of a letter box in the front door a legal requirement in
the UK ?

Dunno. I aint got one, BCO never said I should..



If provision of a letter box is a requirement, now that the post office
counters have a plastic size template limiting the size for first class
minimum postage letter to a narrow slot of 165 mmm x 5 mm, perhaps we can
reduce our aperture to that size and still meet the regulation.

Regrettably even this would not stop junk mail coming through it.


Nothing stops junk mail.
