How much are single-letter number plates worth?
A single letter paired with digits. Not every single-letter registration has the same demand or value.

DVLA charges £80 to take a registration off a vehicle. Assignment after paid retention is free. Include the £80 only if it applies to your transaction; check who pays it and whether commission includes VAT.
About single letter plates
Examples: A 1, X 99. Dateless subset.
- Specific letter and number
- Total character count
- Recent comparable sales and specialist quotes
Compare achieved sales for closely matching registrations and obtain several written specialist quotes. Check commission, VAT, transfer eligibility and the net proceeds before accepting an offer. An asking price is not an achieved sale.
Full number plate valuation guideHow to value a private number plate
Compare the same format, length, initials or name and number pattern. Keep achieved prices separate from advertised asking prices. An unsold dealer listing is not evidence of what a buyer will pay. Request several written quotes and compare the amount you would receive after commission, fees and VAT.
Is this a DVLA number plate valuation?
No. KnowTheCost is independent of DVLA. DVLA sells registration rights through its own service and auctions; those purchase prices do not establish the resale value of your existing registration. You cannot submit your own plate to DVLA's sales auction through this calculator.
Check the right to sell and assign
A personalised registration is a right to assign a number, subject to DVLA rules. Check your V750 or V778 and vehicle eligibility. You cannot use a registration that makes a vehicle appear newer, or transfer a Q/QNI registration. Do not change spacing to make a name read differently on the physical plate.
Taking a number off a vehicle costs £80. A retention document is valid for 10 years; assignment using that paid retention is free. Check the official procedure before accepting payment.
