Boiler service reminder software that books the job, not just the reminder
Most reminder tools tell your customer their boiler service is due, then leave them to phone you. Bookso closes the loop by sending a booking link they tap to confirm a date.

Bookso is built for UK gas engineers who run on repeat work. When you finish an annual boiler service, you log the job, pick a service interval (usually 12 months) and Bookso schedules the next reminder for you. On the due date, your customer gets an email from your business with a one-tap booking link. They pick a slot, you get notified, and the job goes straight into your diary.
It works the same way for CP12 landlord gas safety certificate renewals. Landlords are required to have a Gas Safety Record carried out every 12 months, and a missed renewal is a real risk to their tenancy. Bookso tracks each CP12 by property, sends the renewal reminder before the certificate expires, and lets the landlord rebook the inspection without a phone call. You spend less time chasing certificates and more time on the spanners.
Reminders go out from your business name, with your booking page, and they include your job pricing so customers know what they are agreeing to. You can customise the wording, set the time of day reminders send, and pause reminders for customers who have moved or sold up. There is no separate app for your customers to download; everything happens in the email and on a mobile-friendly booking page.
Start on the free plan, which covers your first 5 customers and includes the booking page, email reminders and the pipeline view. When you outgrow it, Pro is £14.99/month and unlocks unlimited customers, branded reminders and the CSV importer for moving your existing customer list across in one go.
The problem
You do the boiler service, hand over the certificate, and say 'see you next year.' Then the diary fills, the phone rings, and 12 months later that customer has forgotten who serviced them last time. So they Google 'boiler service near me' and someone else gets the job.
Meanwhile you're spending on Facebook ads, van signage or leaflets to find total strangers - while your list of already-satisfied customers goes cold. Every gas engineer who's been going a few years is sitting on a book of repeat work they never actually rebook. The problem isn't finding customers. It's remembering to speak to the ones you already have, at the right moment, in a way that doesn't take an evening on the phone.
How Bookso works for gas engineers
When you finish a boiler service, you log the job in Bookso and pick a service interval - 12 months for most, sometimes 6 for heavy-use commercial. That's it. You forget about that customer and get on with next week's diary.
About 11 months later, Bookso emails and texts the customer from your business name. The message is short and friendly: your service is due, tap here to book. They pick a slot from the times you've said you're available, and the job lands in your diary as a confirmed booking. You get a notification. No phone call, no back-and-forth about dates.
If the customer doesn't tap the link within a few days, Bookso sends an automatic chaser. If they still ignore that, one SMS follow-up goes out on the paid plans. The job then stays visible in your pipeline so you can phone them yourself or skip them - you decide.
This is the important bit, and it's where Bookso is different from every other reminder tool: you don't just see reminders sent, you see bookings confirmed. Most reminder software fires an email and calls the job done. The customer still has to phone you, which most won't. Bookso closes the loop so the reminder actually becomes a booking, not just a nudge into the void.
The whole customer side runs on a mobile-friendly booking page with your name, your prices and your availability. No app to download, no login, no password reset emails. If your customer can send a WhatsApp, they can book a boiler service.
CP12 landlord gas safety renewals
UK landlords are legally required to have a Gas Safety Record (also known as a CP12 or LGSR - Landlord Gas Safety Record) carried out every 12 months on every rented property. Miss the renewal and the landlord's tenancy is exposed; miss the rebooking and you've handed the job to another engineer.
Bookso treats every property as its own customer record. When you complete a CP12, you log the job, and Bookso schedules the next renewal for exactly 12 months later against that property. About a month before the certificate expires, the landlord gets a reminder from your business with a one-tap booking link showing your availability and price. They pick a slot, the inspection lands in your diary, and their tenancy stays compliant.
For portfolio landlords with several rentals, each property sits on its own schedule so renewals stagger through the year instead of piling up in one week. You can note the tenant contact, access notes and boiler details against each property, so the next visit isn't 'where's the meter again?'.
You send one link, the landlord books, the LGSR gets done on time. Less chasing, fewer expired certificates on your record, more predictable months.
Why gas engineers switch from bigger job-management apps
Full job-management suites like Commusoft, Joblogic and Gas Engineer Software do a lot: quoting, invoicing, van tracking, parts stock, engineer scheduling, payroll. They're powerful, and they cost roughly £30 to £70 per user per month, plus setup time to configure everything and get your paperwork in.
Bookso doesn't try to run your whole business. It does one thing: get your existing customers to book you again, automatically. Setup is about 5 minutes - add a customer, pick an interval, done. It's £14.99/month for unlimited customers on the Pro plan, or £44.99/month if you need a small team.
Plenty of gas engineers keep using their existing job-management app for the paperwork and add Bookso alongside it for the rebooking, which the bigger suites don't do well. Others start on Bookso first because they haven't found a full suite worth the price yet. Either works.
Works alongside your existing tools. Already using Gas Engineer Software, Commusoft, Joblogic or a similar full suite? Keep them. Bookso is designed to complement job-management software rather than replace it - it handles the customer-side rebooking loop so your existing tool can focus on quoting, invoicing and paperwork.
Frequently asked questions
How do boiler service reminder texts work?
When you complete a boiler service in Bookso, you set the interval (usually 12 months) and confirm the customer's contact details. About a month before the next service is due, Bookso sends an email from your business name, and on the Pro or Business plan a text follow-up if they don't respond. The message includes a one-tap booking link showing your availability and price. The customer picks a slot and the job lands in your diary as a confirmed booking, not just a reminder that was sent.
Can it handle CP12 / landlord gas safety renewals?
Yes. Each rented property is tracked as its own customer record with its own CP12 renewal date. Bookso schedules the next Landlord Gas Safety Record 12 months after the last inspection, sends the landlord a reminder before the certificate expires, and lets them rebook with one tap. Portfolio landlords stagger naturally across the year instead of all renewing in the same week.
What happens if the customer ignores the reminder?
On the Pro and Business plans, Bookso sends an automatic chaser a few days after the first reminder. If the customer still hasn't booked after that, one SMS follow-up goes out using your included SMS credits (75/month on Pro, 250/month on Business). The customer then stays visible in your pipeline so you can phone them yourself or skip them - Bookso won't keep hassling them or you.
Do I need to move my whole business onto Bookso?
No. Bookso is designed to sit alongside whatever you already use for quoting, invoicing and job management. Keep Gas Engineer Software, Commusoft, Joblogic or your spreadsheet for the paperwork; use Bookso for the customer-side rebooking loop. You can import your existing customer list from a CSV on the Pro plan and be running in about 5 minutes.
How much does it cost for a gas engineer?
Your first 5 customers are free, forever - no card required. Pro is £14.99/month (or £149/year, which saves 2 months) for unlimited customers, email and SMS reminders, chasers and CSV import. Business is £44.99/month (£449/year) and adds team members and more SMS credits. No setup fee, no contract, cancel from settings whenever you like.
Where does customer data live and is it GDPR compliant?
Customer data is stored in the UK/EU region, encrypted at rest and in transit, and Bookso operates under UK GDPR. Customers can unsubscribe from reminders with one tap, and you can export or delete any customer's data on request from your dashboard. Bookso only uses your customer list to send the reminders you configured - we never market to your customers ourselves.
