How we work

Fixed prices, agreed before you arrive

The customer has a fixed price in writing before the job starts. You do the work, not the haggling on the doorstep.

The job on your phone

Our field app holds the job, the address, the photos and the readings. It keeps working where there is no signal.

Paperwork drafted for you

Gas safety records, service records, job sheets and invoices are drafted from the job and checked. You review and approve them.

Tidy, documented work

Every job documented, every space made good, and a proper handover before we leave.
