MCS paperwork holding up handover
Commissioning records, MCS certificates and F-Gas logs scattered across clipboards and your laptop, delaying sign-off and the customer's BUS grant. Capture them on site and store them against the job.

Sound familiar?
The day-to-day headaches heat pump engineers tell us about most — and how Gaffer fixes them.
Quotes lost in heat loss calcs
Homeowners get three quotes and pick the one that lands first. Send a tidy heat pump quote from your phone after the survey and win more installs before the competition replies.
Annual services slipping through the net
Every system needs a yearly service to hold its warranty and efficiency. Gaffer tracks service-due dates and rebooks them automatically, turning one install into recurring revenue.
