District Heating Top Up Locations (SHEAP)

We were pleased to work with Shetland Heat Energy & Power (SHEAP) to develop a "middleware" software solution that extends the life of an existing standalone POS top-up system to make it multi-location, plus adds other benefits.

As a result, the Sound Service Station now also has a facility to top up customer district heating cards (in addition to Bolts Mini Mart), with additional sites now possible.


  • A background application monitors an existing standalone POS application and transfers/injects data into it securely to simulate multi-location
  • SHEAP can now add customers and pair cards at their office (previously was on-site only), which are rolled out to locations
  • Additional invoicing automation (Sage) and statistical reporting was built to capitalise on the POS data, which automates certain admin operations that were once timely
