12 Number Plate Mistakes to Avoid

1. Buying the wrong format

A 7-character current-style won't appreciate. If you're buying for value, look at suffix or earlier.

2. Over-substituting

Three substitutions and most people can't read it. The buyer pool shrinks dramatically.

3. Ignoring the "year letter"

Suffix S is far more common than suffix A. Same name, different prices.

4. Buying without seeing the V750

No V750 = no proof the seller actually holds the plate. Walk away.

5. Forgetting the £80 assignment fee

Always factor it in when comparing prices.

6. Buying on retention without asking why

Sometimes the seller can't transfer it (vehicle ineligible). Confirm before paying.

7. Underestimating insurance impact

Some insurers see private plates as theft signals. Get a quote before committing.

8. Buying overseas plates that won't transfer

Northern Ireland plates work in GB but with restrictions.

9. Not checking the DVLA register

Verify the plate exists, is held, and matches the seller's claim.

10. Paying via untraceable methods

Always use bank transfer with seller's verified account, not cash or crypto.

11. Forgetting to update insurance

Driving with the new reg before insurance is updated = uninsured driving.

12. Selling without a market check

Most sellers undervalue by 20-40%. Get three quotes before listing.
