The maximum fee for a class 4 car MOT is £54.85 and £29.65 for a motorcycle; many garages charge less. You can book up to a month (minus a day) before the current certificate runs out and keep the same renewal date. Take the registration; you don’t need the V5C.
Details are from the DVSA register published 30 Sep 2026 (source). Phone numbers and ownership change, so ring first.
