Spent a bit of time last night researching companies who provide trackday cover. Only got around to completing one online request, which was with Heritage (0121 246 6067). As usual, it came up with "Not enough details, we will need to contact you". Forgot all about it today until a lad called Andrew phoned me at work to get a wee bit more info.
£485 per year.
Must be my second car.
£350 excess with £50 windscreen excess.
Only mod - 4 point harness - no additional premium, as long as disclosed
7,500 (but I could have asked for 10k)
Covers commuting to work (this was an addon at no extra cost)
Trackday Cover
These are unlimited, no need to advise them before doing the event.
BUT You must be a member of the club organising the event i.e. SIDC, SELOC, LOT, etc. Top Marque days are not covered.
There is an additional excess of £1,000 which means that you would have to pay the first £1,350 of any claim (I clarified this with him).
I am 37, have 7 years NCD and the car is garaged in KY15 (Fife). Car is a 1999 S1 135 Sport. The 135 Sport seems to attract an additional premium with most companies as they can never find it on their systems.
Obviously this is no use to you if this is your only car. I am sure I have also seen mentioned that they don't cover you if you are under 28 - but hey, you still have your youth

Last year I paid £439 with Bell. I'll see what their quote is and also try Competition Car Insurance (0115 941 5255, Option 4 - Steve Halham) and AON Esteem (01252 767 139, ask for Lotus Esteem contact).
Hope this info is off use to others
