Just a quickie! I wonder if any body knows of a company that can certificate an existing Cat 1/2 alarm imobiliser in the Lincolnshire/Nottinghamshire area. We need a certificate/letter just to state that it is all working OK to benefit from a large discount on the insurance. It seems that the fears about Transliesure in Newark going to the wall are true so our most obvious point of call is defunct. ALSO.. anbody have any experience of fitting solar panel(s) when there is a Heart interface involved in the equation? I would like to think that the Heart would have something to do with the regulation unless anyone can tell me otherwise. Thanks in anticipation. Mike and Jill.
