I need a list detailing companies (within the U.K, preferably in
england)who can carry out repairs on playgrounds & playground
equipment.

Hi there,

Trentforce, Burton upon Trent
"Our inspectors are fully equipped to make "on the spot" repairs, or
are able to make equipment safe to reduce the risk of any accident."

The Royal Society for the Prevention of Accidents offers a variety of
playground inspections:

A list of registered playground inspectors can be found by clicking on
"Current Members List" at the Register of Play Inspectors site:
http://www.playinspectors.com/

I also looked up playground manufacturers to see if any offered repair
services. As expected, only one mentioned it on their website, because
it would imply that these products that need to be extremely safe,
could break or fail.

Castles in the Air offer play area maintenance and post inspection
refurbishments to bring your playground back to EN-1176 standards.
They are based in Wiltshire.
