You can book your Theory Test online via the offical website for all government services - DirectGov.
Booking your Theory Test is a very simple and straightforward proceedure which will only take a few minutes and you will pay ONLY for the test itself - there is no extra "booking fee" or "administration fee" added on.
There are a worrying number of official looking "Theory Test booking services" springing up on the internet who will book a test on your behalf - BUT they will charge you a sizeable booking fee on top of the test fee.
To book your Theory Test online via DirectGov you need;
* your driver number (from your driving licence)
* a credit or debit card with which to pay the £31.00 test fee
You can choose the date and time to suit you and if you later find you need to change the date or cancel your Theory Test you do so via DirectGov - you have complete control over your booking.
THERE'S NO NEED TO PAY EXTRA FOR YOUR THEORY TEST - book your test yourself directly with the DSA at the following link;
