How to Send Professional SMS Reminders to Customers (Without Looking Spammy)
TL;DR: SMS appointment reminders reduce no-shows by 30-40% for UK trade businesses. This guide covers: when to send reminders, what to include in your messages, UK SMS regulations, automation tools, and real message templates you can copy. Includes examples for window cleaners, landscapers, and installers.
Why SMS Reminders Matter for Trade Businesses
You booked 8 jobs for tomorrow. By the time you drive across town, 2 customers have forgotten, 1 isn't home, and another "thought it was next Tuesday." That's 3-4 hours wasted and £200-400 in lost revenue.
❌ No SMS Reminders
- • 20-30% no-show rate
- • Wasted fuel & time
- • Lost revenue
- • Frustrated customers

When to Send SMS Reminders (Perfect Timing)
Timing is everything. Send too early and customers forget again. Send too late and they've already made other plans.
Recommended SMS Schedule:
Booking Confirmation (Immediate)
Send instantly when appointment is booked
Example: "Hi John, your window clean is booked for Tuesday 14th Feb at 10am. We'll send a reminder the day before. Reply STOP to cancel."
24-Hour Reminder (Day Before)
Most important reminder—send between 4-6pm
Example: "Reminder: We're visiting tomorrow (14th Feb) at 10am for your window clean. See you then! ABC Windows."
On-The-Way SMS (Optional)
Send 30-60 minutes before arrival
Example: "We're on our way! Will arrive in 30 minutes. Thanks, ABC Windows."
Payment Reminder (After Job)
For customers who didn't pay on-site
Example: "Thanks for your custom! Your £35 payment is due. Pay via bank transfer: Sort 12-34-56, Account 12345678. Quote ref: WC140225."

UK SMS Regulations (Stay Legal)
UK GDPR & PECR Requirements:
- ✓ Get explicit consent before sending marketing SMS
- ✓ Appointment reminders = "service messages" (consent not required if part of service)
- ✓ Always include business name in message
- ✓ Provide easy opt-out method (Reply STOP works)
- ✓ Don't send between 9pm - 8am (annoying + illegal)
- ✓ Keep records of consent
- ✓ Honor opt-out requests within 24 hours
Manual vs Automated SMS Systems
📱 Manual SMS (Small Scale)
Good for 1-20 customers per day:
- • Send from your mobile
- • Free (uses your plan)
- • Personal touch
- • Time-consuming
- • Easy to forget
🤖 Automated SMS (Scale Up)
Essential for 20+ customers per day:
- • Send to hundreds at once
- • 3-6p per message
- • Never forget reminders
- • Schedule in advance
- • Track delivery status
How to Automate SMS Reminders (Simple Setup)
Most UK trade businesses use a contact management system to automate SMS reminders. Here's how it works:
Step-by-Step Automation:
Import Customer List
Upload CSV with names, phone numbers, and postcodes
Create Message Template
Use variables like {first_name}, {date}, {time}
Set Trigger Rules
E.g., "Send 24 hours before appointment time"
Messages Send Automatically
System handles everything—you focus on the work
Common SMS Reminder Mistakes to Avoid
Sending too many messages
Max 2-3 per booking (confirmation + reminder + on-the-way). More = annoying.
Vague timing
"We'll be there Tuesday morning" ❌ vs "Tuesday 14th at 10am" ✅
No business name
Customers get messages from strangers. Always sign off!
Using ALL CAPS
Looks unprofessional and aggressive. Use normal case.
Forgetting opt-out info
UK law requires it. Add "Reply STOP to opt-out"
Real Example: Sarah's Window Cleaning Round
Sarah runs a window cleaning business in Leeds with 400 customers. Before SMS reminders, she had 15-20% no-shows. Here's what changed:
