[2] The hamlet of Chaul End lies in the north of the parish, and at the border with Luton there is Caddington Park with Skimpot in its postal address.

The place-name 'Caddington' is first attested in a list from circa 1000 AD of the manors of St Paul's Cathedral in the Parker Library of Corpus Christi College, Cambridge, where it appears as Caddandun.

Much of Caddington is now urban and there has been much residential development in recent years with the provision of local facilities such as shops, schools and a public hall.

Caddington still retains its village green and nearby is the medieval parish church, restored in Victorian times.

The parish of Caddington historically straddled Hertfordshire and Bedfordshire, with the boundary running from north to south through the middle of the village itself.

At the southern end of the parish it included part of the village of Markyate, where a chapel of ease was built in 1734, dedicated to St John the Baptist.

[8] Proposals were put forward in 1888 to also make Markyate a civil parish and rationalise the boundaries between Hertfordshire and Bedfordshire in this area, but were not implemented.

[12] on 1 January 2001 it was renamed back to "Caddington",[13] Slip End became a separate civil parish on 1 April 2001.

Football and Cricket fixtures are hosted at the Caddington Recreation Association in Manor Road which, as well as providing sports facilities also has a bar and hall for hire.
