Best quote so far from Swiftcover at £870 Fully Comp. Just posting this for the benefit of others to check it out as the normal price comparison websites didn't show a result from these guys. I've spent most of my day off today ringing up for quotes from the little specialists to the bigger groups.
I've always declared everything but Swiftcover state they don't mind a stainless steel exhaust or light/lamp modifications as long as they are legal and approved so nothing went up further (I have a Jetex and M3 rears)

HIC TPFT renewal was £1399. Th fully comp price was no better.
Chris Knott couldnt do it under the forum deal because I had a Mk3 1.8 prior to my Mk3 16v. Had a Mk2 16v as a first car so though I'd get away with it

Everyone else wanted me to go away by saying £1700 and above.
To put in to perspective I'm 26, (touches wood) have 5 years no claims, clean license, CAT 1 Toad and live in North London.
I really feel sorry for you young uns around. I was so close to giving up until I saw the Swiftcover advert on a random website!
