How Wigan Car Mechanics Can Use AI to Send MOT and Service Reminder Texts

A customer brings their car into your garage in Hindley for a full service. You do a great job, they leave happy, and you never see them again. Not because you did anything wrong, but because twelve months later their MOT was due and they just Googled "MOT near me" and booked with whoever came up first. That's a booking you should have had. AI-powered reminders can stop that from happening.

The Revenue You're Losing by Not Sending Reminders

Most garages in Wigan have a decent customer base built up over the years. The problem is that customers don't naturally think about MOT dates until they get the DVLA reminder letter, and by then they're already searching around for the cheapest option.

If your average MOT and service brings in £150-£300, and you have 200 regular customers, losing even 30% of them to other garages each year is a significant amount of money walking out the door.

A basic reminder system costs almost nothing to run and keeps your name in front of customers before they start looking elsewhere.

Storing MOT Expiry Dates: Where to Start

The first step is getting customer MOT dates out of your head and into a system.

If you're using garage management software like Mechanic Desk or AutoTrader Dealer, you likely already have somewhere to record this. If not, even a spreadsheet with customer name, registration, phone number, and MOT expiry date is enough to get started.

For new customers, make it a habit to log the MOT date at every visit. For existing customers, you can use the DVLA MOT history API (available free at api.gov.uk) to look up any UK registration and get the current MOT expiry date. This means you can build your reminder list from your customer records without needing to call everyone.

Once you have a list, you can connect it to an automation tool like Zapier to trigger messages at the right times.

Setting Up Automated Reminders at 30 and 14 Days

The sweet spot for MOT reminders is 30 days before expiry (enough time to book, not so early it feels irrelevant) and again at 14 days (urgency without panic).

Using a tool like Zapier connected to your spreadsheet or CRM, you can set up a simple rule: when today's date is 30 days before the MOT expiry date in column D, send a text message to the number in column C.

SMS tools like TextMagic, SimpleTexting, or even WhatsApp Business can send these messages at a cost of a few pence per text.

If you're using a more complete garage CRM like GaragePlug or Holt Lloyd's software, many of these have built-in reminder features that handle this without needing Zapier at all.

Using AI to Write the Reminder Messages

The messages themselves matter. A text that reads "MOT DUE SOON - CALL US" feels cold. A message that uses the customer's name, mentions their car, and includes a direct booking link will get a much better response.

Here's how to use ChatGPT to write your templates. Give it a prompt like:

"Write a friendly SMS reminder for a car garage in Wigan. The customer's name is [NAME], their car is a [MAKE MODEL], and their MOT is due in 30 days. Include a booking link placeholder. Keep it under 160 characters, friendly but not cheesy."

You'll get something like: "Hi [NAME], your [MAKE MODEL] MOT is due in 30 days. Book with us before it slips: [LINK]. Any questions, give us a call - [GARAGE NAME]"

Write three or four versions and test which one gets more bookings. Claude or Gemini can also help you write these, and you can ask for tone variations (more casual, more urgent, more reassuring) to suit your customer base.

Integrating With Your Booking System

The reminder is only useful if it's easy for customers to act on it immediately. That means including a direct booking link.

Calendly has a free plan that lets customers pick from your available slots without calling. You set your working hours, block out any days you're busy, and the link does the rest. Customers click, pick a time, and you get a notification.

For garages that want something more trade-specific, Booksy or SimplyBook.me let you create service menus (MOT, full service, oil change) with different durations so slots are blocked out correctly.

When a customer books via the link, you can set up an automatic confirmation text and a reminder the day before their appointment, again using Zapier or the booking tool's built-in features.

Tracking What's Working

Once the reminders are running, keep an eye on two numbers: how many reminders are being sent, and how many bookings come in the week after each send.

Most SMS platforms show delivery rates and, if you're using a link shortener like Bitly, click-through rates too. If your 30-day reminder is getting low clicks, try a different message. If the 14-day reminder is converting better, you might shift more effort there.

Even a basic tracking system, a note in your spreadsheet of how many bookings came in after each send, gives you enough to make decisions over time.

A garage in Standish that sends 200 MOT reminders a month and converts even 40% of those to bookings is looking at roughly 80 guaranteed MOTs, before any walk-ins or new customers.
