The Problem
You are a Gas Safe engineer,
not a paperwork machine.
Admin is eating into your profits. Stop wasting hours on tasks that should take minutes.
20+ mins
per certificate
Paper CP12 pads
Filling in paper pads, photographing them, emailing to landlords, then filing a copy. Every single certificate.
4+ jobs
lost per month
Chasing renewals manually
Trying to remember which landlord's CP12 expires when. Losing jobs to other engineers because you forgot to follow up.
2+ hours
wasted weekly
Invoices in Word documents
Copy-pasting last month's invoice, changing the date, forgetting to include VAT correctly. Every month.
Gasdesk handles the admin so you can focus on the job.
Everything you need to
grow your business
Stop drowning in paperwork. Gasdesk handles the admin so you can focus on what matters — the jobs.
