[3] The National Accident Helpline was formed in 1993[4] by two businessmen, Alan Kennedy and Paul Follett,[5] along with the Northampton legal firm Tollers.

[15] National Accident Helpline has never cold called and in December 2014 the personal injury advice service confirmed it would no longer be contacting prospective customers by email.

In July 2015, National Accident Helpline founded the Ethical Marketing Charter alongside seven other personal injury firms.

The first set used from 1997 to 1999 featured the spokeswoman (Teresa Quigley) telling people that if they had an accident which wasn't their fault, they could be entitled to compensation.

In 1999, people took on a more active role, still featuring the same spokeswoman at the start and end, as they shared their story of accidents and what the company did to earn them their compensation.

The most famous one includes a woman named Katy Freeman, whose advert is the longest-running of all appearing from 2003 and edited occasionally until 2009, who was walking into an office reception and did not know the floor was wet because there was no warning sign.

She then explains how worried she was about claiming, but was assured by the National Accident Helpline that they run on a no-win, no fee basis and got £5,000 in compensation.

Another features a man named David Morris, who was unaware he received the wrong type of ladder whilst installing a fire alarm system in a house wall.

Beginning with the accident with no name tag featuring the spokeswoman again and going back to the victim, saying how much they earned in compensation and what happened afterward.

The Freeman and Morris adverts were re-edited to include the modified logo and music (except the last ten seconds faded out into the old jingle) while the others were dropped.

The ads feature the tagline "When it's wrong, make it right" National Accident Helpline has been involved in a number of charity partnerships.

A team of four senior employees ran the 2010 London Marathon in aid of the Juvenile Diabetes Research Foundation, raising over £6000.
