Annual Service & CP12 Reminders for Heating Engineers
Keep your diary full year-round - every customer holds their own next-due date for the annual boiler service, Gas Safety Certificate or AC maintenance, and the reminder goes out on time without you tracking it. Remindlo works on top of the diary or job system you already use, with no spreadsheets.
No credit card required. Set up in 2 minutes.

The Hidden Cost of Forgotten Services
Every skipped boiler service and expired Gas Safety Certificate costs you more than you realise
60% Skip Annual Service
Homeowners forget or delay boiler services. They only call when something breaks—usually not you.
£80-150 Lost Per Service
Every missed appointment is revenue walking to a competitor. Multiply by hundreds of customers.
Seasonal Chaos
Winter is chaos, summer is dead. Without year-round service reminders, income is unpredictable.

What Remindlo users say
“Easy to install and setup new campaigns for small and medium businesses. Free up to 10 SMS per month so you can try without worrying about the bill.”
“I run a small biz and that plugin saves me a ton of time. Works in the background, since I also enabled the auto-sync option. No extra work for me, events with phone numbers are picked up automatically for the reminders; I'm already busy with other stuff so that's good. Using two out of three default workflows - per-visit reminders and post-visit thank you notes to collect reviews.”
