As you might imagine, this situation has been being monitored quite closely by other marque clubs for some time, and as you might further imagine, the situation is not quite as simple as 'over 40, no MoT'.
Concise summary of conditions here:

It will remain the case that the user of a vehicle, regardless of its age, on public roads must ensure the vehicle is roadworthy. Of course, one easy way to do that is to get an MoT test. However, one might ask, suppose a vehicle which does not legally *need* an MoT is submitted for the test anyway, and fails, can the vehicle be used regardless? The answer is "no", because the failure result will be recorded automatically with DVLA by the MoT test station. That will officially record the vehicle as unroadworthy, hence invalidating your insurance.
Some argue that this will encourage people *not* to get their cars tested at all, not even an unofficial safety check by the local garage, leading to dangerous cars being allowed to continue on the roads. Time will tell.
One point raised on another forum I've seen cites the example of an MoT failed by a trivial fault, such as a blown brake light. This is the only fault rendering the vehicle not roadworthy. The owner, knowing this is easily fixed, changes the bulb, thereby making the vehicle *in fact*, roadworthy. However, legally it remains recorded at DVLA as UNroadworthy. Where does that leave the owner's insurance position?
Is this a can of worms in the making? Very likely ! So don't be too keen to abandon the MoT test just yet, it might be prudent to see how things work out in practice for a year or so. And then of course, there's the impact on this pan-European legislation of Brexit ....
