UK fields and postcode QA

Field	Typical value	What to test
Premise	Number, building name, or flat	Do not assume the first value is numeric
Street / locality	Street plus optional locality	A blank locality must not damage line order
Post town	Often displayed in capitals	Do not require county as a substitute
Postcode	For example, SW1A 1AA	Normalize case and preserve one central space

Example layout

Alex Morgan
Flat 4
18 King Street
LONDON
SW1A 1AA
UNITED KINGDOM

Boundary cases

A named building has no street number.
Postcodes use different valid lengths.
Input arrives in lowercase with extra spaces.
An optional county is incorrectly required.

Postcode normalization test

Submitted value	Expected presentation	Failure signal
sw1a1aa	SW1A 1AA	The value is rejected only because case or spacing differs.
M1 1AE	M1 1AE	A fixed eight-character rule rejects a shorter valid shape.
Flat 4, 18 King Street	Flat and street remain distinct lines.	The flat disappears when a label is rendered.
Rose Cottage	Named premise remains valid without a street number.	A digits-only premise rule blocks submission.

Test input, save, address-book editing, checkout display, and CSV export. Normalization should be visible and reversible; it cannot establish that a postcode is active or belongs to the generated premise. County should remain optional when the post town and postcode provide the required routing context.
