Hey Gaz
I do.
Warranty Direct. Read their Policy wordings (available on their website), front to back. And read again. They do make claiming a horrendously tortuous process, but be patient, then persistent, be prepared to stand your ground, make sure it's a valid claim, fight them on the beaches etc and Hey Presto! They do part with money! Mine isn't a bad policy, far from it in fact, but they do need some 'encouragement' to fulfill their obligations. But be aware it may not happen in a timely manner.
Not the best recommendation, but it's all the advice I can offer! (mine cost me £800 last Sept, IIRC, but has paid out multiples of that).
What car do you have?
