LPG certificate

Having a couple of problems with a LPG 110 I have bought. It didnt come with a certificate to state that it has been fitted correctly and am finding it difficult to insure.
Is it easy to obtain the certificate and can anybody recommend a garage in the Merseyside area that can check my landy over and issue the certificate.
Thanks

Ask for Martin Webster. I don't know if they offer this service but what he doesn't know about LPg isn't worth knowing.

.Admiral might be worth a try as when I got my LPG converted Freelander V6 they did not even ask about the certificate,or want to recieve any documents concerning the LPG fitting.I think any LPGA member can check over the system and provide a certificate for you,cost around £50 or so,not totally sure though.
