yeah you do have to get your car certed if its lower the 100mm of the ground no matter what springs you have
this thread aint about that though is it its about getting springs compressed which you dont have to get a cert for unless it makes your car go lower than 100m off the ground which

EVERYONE knows
Maybe you should actually read the rules rather than just making them up?
Springs and shock absorbers • the springs or shock absorbers are direct replacements, and
• replacement springs fit and maintain contact with un-modified OE seats throughout
full suspension travel, and
• replacement springs are self-retaining in their seats at full extension, without the use
of non-standard devices such as wire-ties, straps, or external spring locators, and
•
replacement springs have not been heated or cut, and
• springs and spring seats are not height adjustable (unless OE), and
• replacement shock absorbers fit un-modified OE mountings, and
• suspension maintains sufficient travel for safe operation when fully laden, and
• suspension components maintain sufficient clearance from unmodified bumpstops
when fully laden, and
• a minimum of 100 mm ground clearance exists below any part of the vehicle
structure, or any steering, braking, or suspension component1, and
• the normal relationship between front and rear suspension height is not unduly affected.
Notice the AND at the end of each of those points? You have to meet all the requirement not just the ones you like. If you don't meet all of them it has to be certed.
