Every vehicle you have ever worked on has an MOT date. That is a list of customers who are guaranteed to need something, on a date you can know in advance, which makes MOT reminders the cheapest work a garage can win.
Most reminder systems fail anyway. It is worth being precise about how, because the failure is not the one people expect.
The failure is not the message. It is the date.
Garages tend to blame the reminder itself: wrong wording, wrong timing, wrong channel. Occasionally true. Far more often, the message went to the right person at the wrong time, because the date behind it was wrong.
Here is how a manual list goes stale. You record a customer's MOT expiry when you test the car. Twelve months later, they had it done somewhere else: a tyre place, a main dealer, a mobile tester, somewhere on holiday. Their real expiry date is now a different day, and your list does not know. You remind them three weeks after the car was already tested.
That reminder does not just fail. It tells a customer you are not paying attention.
And the failure is invisible from your side. Nothing in your system says "this date is wrong". The list looks healthy right up until the point you notice the response rate is a third of what it should be, and by then it has been wrong for a year.
A date that maintains itself
The fix is not a better spreadsheet. It is a date that comes from the only source that always knows: the DVSA MOT history for the registration.
When the expiry date is read from DVSA rather than typed in from a certificate, it updates when the vehicle is tested, by you or by anyone else. A customer who went elsewhere last year is still on your list, with the correct date, and gets reminded at the right moment this year. You get a second chance you would otherwise never have known you had.
That is what our MOT reminders are built on, and it is the whole reason the feature exists.
Write it like a person
Once the date is right, the message matters. Three things separate a reminder that produces a booking from one that produces nothing.
Say when, specifically. "Your MOT is due on 14 March" beats "your MOT is due soon". A specific date creates a deadline; "soon" creates a vague intention.
Give enough notice to be useful. Three to four weeks is the usual answer. Long enough to plan, short enough to still be relevant. Too early and it gets forgotten; too late and the customer books wherever has a slot.
Let them act on it immediately. This is the one most garages get wrong. A reminder that ends with "call us to book" converts a customer who was ready into a customer who has to remember to phone you tomorrow. A link to your online booking page turns the moment of reading into a slot in the diary.
What to expect
Be sceptical of anyone quoting you a percentage uplift. It depends on your customer base, your area, how long your list has been neglected and how much of it is stale.
What is predictable is the direction. A garage moving from a manual list to DVSA-sourced dates typically finds two things at once: some customers it had stopped reminding entirely, and a set of dates that were simply wrong. Both are recoverable.
The work is already yours. It just needs the right date and a message that can be acted on.
Do not only remind about the MOT
The MOT date is the hook, not the whole opportunity.
A car coming in for an MOT is a car you can also service. If your reminder says "your MOT is due", you get an MOT. If it says "your MOT is due on 14 March, and your last service with us was eighteen months ago", you have offered two things and made the trip worth more to both of you.
The same applies to work the customer already declined. An advisory from last year is a conversation you have earned the right to have.
The one to get right first
If you do nothing else with reminders, fix the dates.
A perfectly written reminder sent on the wrong date is worse than no reminder. It tells a customer you are not paying attention, which is exactly the impression a reminder exists to counter. Wording can be improved any time. A stale list quietly gets worse every month you leave it.
