How It Works for Gas Engineers
Most gas engineers are still doing invoices on the laptop at 10pm, or writing them up on a notepad and photographing them on their phone. Both approaches are slow, unprofessional, and mean you're leaving money on the table — research consistently shows same-day invoices get paid significantly faster than end-of-week invoices.
TaskDrop is different. It lives entirely in WhatsApp — the app already on your phone. You type INVOICE or QUOTE, answer six short questions about the job, and receive a professionally branded PDF invoice in under 60 seconds. You can forward it to your customer straight from WhatsApp before you've even started the van.

Why Gas Engineers Get Paid Slower Than They Should
The main reason gas engineers don't get paid on time isn't that customers don't want to pay — it's that the invoice arrives late, or doesn't look professional enough to prompt immediate action, or there's no follow-up when the due date passes.
Same-day invoicing is the single biggest change most gas engineers can make. When you invoice from the driveway while the customer is still thinking about the job, there's no gap for them to forget, lose the invoice, or dispute what was done. Payment is psychologically easier when the work is fresh.
Automatic reminders handle the awkward follow-up. Most tradespeople hate chasing money — it feels confrontational. TaskDrop sends professional, politely worded reminders at 7, 14 and 21 days without you having to do anything. Most late payments resolve on the first reminder.
Gas Engineer Call-Out Rates Across the UK
Gas engineer call-out rates range from around £60–£80 in northern cities up to £100–£150 in London for a standard boiler service or fault diagnosis. Emergency out-of-hours rates are typically 50–100% higher. Whatever you charge, TaskDrop invoices it correctly with your Gas Safe number included.
