The Motor Insurance Repair Research Centre, or Thatcham is a business wholly owned by the insurance industry covering all aspects of vehicle insurance liability. Look at http://www.thatcham.org/about/
Basically, if you produce a vehicle model, you present it to Thatcham and they try and break into it along with various other tests like how cheap or expensive it is going to be to repair it. They then approve or reject the various aspects. This directly affects your insurance. Though why they ask us if it is a Thatcham approved system when their own company has already decreed whether the vehicle is approved, is beyond me. Perhaps we should fill that box in with the words "I DON'T KNOW! YOU TELL ME." Although seriously it is usually mentioned in the brochures because it is a feather in the manufacturers cap. The same as NCAP http://www.euroncap.com/home.aspx
And if it's a factory fitted one, don't think your going to save a few quid by fitting a thatcham approved one to, because all you'll do is cause no end of problems and possibly void your warranty with it directly effecting your cars electronics. I found with my motorbikes though that the difference between a standard fit and thatcham system is very small when it comes to your insurance premium.
Did you know Richie fitting a Datatag to your bike does not make cheaper insurance, so why pay £60 for datatag and you get no discount. I doubt an alarm would reduce it enough to warrant the initial outlay, and who takes any notice of an alarm going off ? An immobiliser is the best thing to have as its fitted as standard on all cars and most bikes now and is a very good theft deterrent.
That's why I got the microdots. Half the price and...if the police ever bothered is a good way of finding bits of your bike if not the whole thing. The only reason I looked into is was because I was interested in getting an alarm but as you say, £100 for an alarm and the price per year came down £5 on my insurance. Hardly worth it. So have stuck to the immobiliser and having a V4 I just pop off one to the ignition leads. It's under the tank so won't get effected by rain and most thiefs won't have a clue when they get popping and spluttering down the road. Edited by: RichieD76
Aaaah, reminds me of the immobilisers on the old ford escort mk 1 and 2. Open bonnet, unclip distributor cover, remove rotor arm and stick it in your pocket, refit distributor cover, close bonnet.
Upon your return, get in car, try and start, swear atit,then remember rotor arm is stll in pocket. Happy days!
