- 1 in 3 reminders turn into jobs
- £23 earned per reminder on average

A simple setup. Then it runs itself.
Setting up boiler service reminders with GES is quick and easy. Ask us to import your customers, personalise the reminder template, and watch your customers book jobs in year after year.
Issue a certificate
Send it to the customer from site, and the job address's next service date moves on a year automatically.
The reminder is scheduled
Edit your reminder template and choose how far in advance it goes out. GES automatically sends it next year.
Customer books in
They pick a time through the online booking link, and it lands in your calendar. Or they just give you a call.
Email, SMS, or both — it’s your choice
Email reminders that sound like you
Every reminder goes out under your business name, in your own words. Add a booking link and customers can pick a time without picking up the phone.
- Unlimited email reminders on the Core and Pro plans
- Change the subject, wording and timing whenever you like
- A "Book online here" link that drops bookings into your calendar PRO
A quick text for the ones who never check email
Some customers live in their texts, and some don't have an email address at all. An SMS reminder reaches them too, straight to their phone.
- Short, editable text for gas and oil service reminders
- Pay as you go: 10p per text plus VAT
- Add the online booking link to your texts as well PRO
Send both, and more customers book in
The email does the explaining and the text gets noticed. Both go out automatically from the same service due date, so there's nothing extra to keep on top of.
- Set up once, then every certificate you issue queues the next reminder
- Reach customers whichever way they prefer
- Turn reminders off for any customer who asks
ONLINE BOOKINGS
Let customers book themselves in
Add a booking link to your service reminders, and customers can pick a free slot in your diary without picking up the phone. That means fewer calls to return and no back-and-forth over which day works.
- Set availability and timeslots for each engineer
- No form for your customer to fill in
- Booked jobs land in your calendar and confirmations are sent to you and the customer
Hi :firstname,

AUTOMATED REMINDERS
Frequently asked questions
Got a question we haven't covered? Talk to our team.
How do automated reminders work for heating businesses?
Whenever you issue paperwork to a customer, (this could be a gas certificate, invoice, or quote) our software records this date. Depending on what you sent, a reminder will be sent out after a specified amount of time. These reminders can be either emails or SMS. For an invoice, a reminder might be sent after 2 weeks, while a service reminder is normally 11 months later.
Can I change what my reminders say?
Absolutely! All of our reminders are customisable. You can write anything you like while also making use of our drag-and-drop shortcut tags like :firstname and :propertyaddress which will automatically fill with the customer’s unique information.
What kind of automated reminders are useful for a heating business?
We’ve devised three different types of reminders useful for heating businesses. Quote and invoice reminders simply follow up on the paperwork you send to customers, helping you get paid faster and win more jobs. However, our most profitable feature is our service reminders. These help you capture more repeat business from the yearly servicing you do for many customers.
Can I set which customers receive reminders?
Yes. If a customer has requested to not receive reminders, you can simply turn off automated reminders from that customer’s profile.
How do service reminders help me with profitability?
Since landlords and most homeowners get their gas appliances serviced each year, these service reminders are a great way to keep the same customers. It’s cheaper and more effective than finding new ones, and also prevents your customers from going to one of your competitors instead (if they received a leaflet through the door, for example) You can read more about the benefits of repeat business in our article here.
Is there any risk storing only digital copies of my records?
Keeping your records stored on Gas Engineer Software is extremely safe because we use bank-level encryption and keep frequent backups. Going paperless also means you won’t have to worry about floods, leaks, damp, fire, and simply misplacing records. More on data security here.
Does GES send reminders for heat pump servicing as well?
Yes. GES tracks the service due dates for gas boilers, oil boilers, and heat pumps. While gas boiler service due dates are stored against the job address, oil boilers and heat pumps are tracked on the appliance. Each have their own separate service email template which you can customise in your settings.
