How is this worked out?

We take your one figure and compare your current system with a modern, high-efficiency one doing the same job. A new system delivers the same heating or cooling while drawing far less energy, and that difference is your saving.

If you enter your bill or energy use we work from that directly. If you enter floor area, we first estimate your energy use from a standard commercial benchmark. We assume gas at 7p/kWh, electricity at 26p/kWh and current UK carbon factors.

It's a quick guide, not a quotation. The larger and busier your premises, the bigger the saving, so a full survey gives you the exact numbers.
