Not a very clearly defined area:
Chambers describes it as the
counties into which the
London conurbation has spread - taking these from the time prior to the
local government reforms of 1973 this would mean
Middlesex,
Essex,
Kent and
Surrey. A defining concept might be that of the areas within reasonable commuting distance of London (ignoring the fact that a combination of ludicrous property prices and high salaries means that there are a few nutters commuting in daily from
Doncaster and
Bristol); that would at the very least add
Hertfordshire,
Buckinghamshire,
Berkshire and
Sussex to the list, and probably
Oxfordshire,
Hampshire and
Suffolk, although possibly only parts of those counties are really "home counties" in character. That character is much as
zakale and
freezeup describe it, although the areas delineated include a lot of what would be highly attractive countryside (the
Chilterns, the
Downs, the
Weald,
Ashdown Forest ...) if it wasn't full of
estate agents in
hot hatches,
golf clubs and
garden centres and that description could probably be applied to most of
England if looked at with a jaundiced eye.
