Just thought I'd post a few notes on insuring a car with an LPG conversion in case anyone needs to know in future. It took me a bit of time to find all of the relevant information!
As it stands today (August 2006), most insurers will want you to have a certificate from an LPGA approved installer before they will agree to insure an LPG converted car.
The LPGA are an independant body who try to regulate LPG conversions in the UK and are fairly active in trying to persuade insurance companies that they need to have this approval.
There's a fairly comprehensive list of insurers who require this certificate at
this site.
However, it's presently perfectly legal for a non-LPGA member to fit an LPG conversion, so there are quite a few non LPGA-approved cars around, like mine.
These cars may have no certificate at all (DIY conversion, perhaps), a certificate from a perfectly competent fitter who isn't an LPGA member, or perhaps an independant engineer's report verifying the quality of the work. Ultimately, the resale price of these cars
is affected by the lack of LPGA certificate because of insurance difficulties.
The good news is that there are still companies that will insure these vehicles, though, including:
* NatWest - They just class the LPG conversion as a mod, no additional charge, no certificate required.
* Co-Op - Need a certificate from an LPGA installer, but it's OK if they didn't originally fit it. (No idea if anyone would actually issue you with this certificate, though!)
* Norwich Union - Engineer's report needed
* NFU - Engineer's report needed
Hope that's of some use to somebody and that people use the listed insurers rather than being tempted to 'just not mention it' to their existing insurer - I'm sure a lot of people do this!
