The two companies have formed Spurs Insurance Services. The venture will be advertised in Spurs' fanzine, on its website and in the local press.
Other promotional activity will include direct mail and email marketing using the club's database.
As an incentive to request an insurance quote from Endsleigh, fans will be offered the chance to win prizes such as signed team shirts.
For every policy taken out, Spurs Insurance Services will donate a percentage to club projects, including improvements to its youth academy.
