Yep! Basically, if you've owned it over a year, it'll qualify as a 'Personal Import'. Look that up...
Took me 5 seconds on Google (searching for 'Personal Import') to get to this...
Standard SVA will apply only for the following main categories of imported vehicle
1: Any "personally imported" vehicle as defined below
What is a Personal Import?
With effect from 1 February 2001 you are a personal importer only
a. if the vehicle has been imported by a person entering the United Kingdom;
b. that person had, at the time the vehicle was imported, been normally resident in a country other
than the United Kingdom for a continuous period of at least 12 months;
c. that person intends to become normally resident in the United Kingdom;
d. the vehicle has been in the possession of that person and used by him in the country where he has
been normally resident for a period of at least 6 months before its importation; and
e. the vehicle is intended for his personal or household use in the United Kingdom.
What the applicant will need to produce as evidence of meeting the above criteria:
1a. Outside the EC C+E 388 as proof of 12-month continuous residence. (No other custom forms
will be accepted as a substitute for this).
1b. Inside the EC documents such as household bills will be accepted as evidence but they must
cover the 12-month period.
or
2. ownership document or Registration document plus insurance document or service invoices for the
vehicle covering the 6-month period. NB the European Community countries are: Austria,
Belgium, Denmark, Finland, France, Germany, Greece, Eire, Italy, Luxembourg, the Netherlands,
Portugal, Spain, Sweden the UK, ,. Cyprus, The Czech Republic, Estonia, Hungary, Latvia, Lithuania,
Malta, Poland, Slovakia and Slovenia
NB the original documentation is needed

I'm sure you can try and find the rest...
TBH, your best bet is to phone/email the DVLA/VOSA who will be the best people to explain it to you.
