The problems you face every day

If any of these hit close to home, you're in the right place.

Annual servicing reminders

Hundreds of customers need annual boiler servicing. Tracking who's due and when — and chasing them to book — is a full-time job.

Emergency vs planned work

Balancing emergency breakdowns with pre-booked maintenance means your schedule is constantly shifting.

Certification management

Gas safety certificates, F-gas records, and service logs need to be stored and retrievable. Paper systems don't cut it.

Parts ordering

Engineers identify the needed part on-site but ordering and tracking delivery adds days to the repair.

How SlotFixer helps

Features built for hvac businesses

Every tool you need to schedule, manage, invoice, and grow — purpose-built for the way hvac companies actually work.

Recurring Service Schedules

Set up annual, bi-annual, or quarterly service reminders. Customers get notified when their service is due — and can book through your portal.

Emergency Dispatch

When a heating breakdown comes in, find your nearest available engineer and dispatch them instantly with job details and customer history.

Compliance Documentation

Attach gas safety certificates, photos, and test readings to every job. Everything is stored digitally and linked to the customer record.

Service Checklists

Standardised checklists for boiler servicing, AC maintenance, and installations. Every engineer follows the same process.

Parts & Inventory

Track van stock, log parts used, and flag when spares need reordering. Reduce return visits caused by missing components.

Digital Contracts

Maintenance contracts and care plans — send, sign, and manage them digitally. Automatic renewal reminders keep revenue flowing.

On-Site Payments

Collect payment the moment the job is done. Send a payment link and the customer pays by card — no chasing.

Customer Portal

Customers view their service history, access certificates, book their next appointment, and pay outstanding invoices online.

Business Insights

Track engineer utilisation, average job time, first-time fix rate, and revenue per job type. Make smarter business decisions.

Route Planning

Optimise daily routes for service calls across your coverage area. Less driving, more fixing.

The recurring service scheduling alone was worth it. We used to lose track of who needed their annual service — now customers book themselves through the portal.
