Three sites, three periods, all whole-period figures from each site’s own meter data. Every percentage carries the period it was measured over, because the period is what makes it meaningful.

Measured energy savings over whole monitored periods. Electricity rates are supplied by each customer and range from 24p to 30p per kWh, so the rate is printed next to every £ figure. £ savings are not comparable between sites and are never averaged or totalled.
A three-month spring window, the strongest part of the year, which is why it is our highest figure.

Monitoring was not continuous across this span: no data for February 2026, and a wifi outage 2 to 17 July 2025.
The 57% is the whole period, including the diesel saved on the generator. The £ figure is on the grid basis only.

The same site read 37% across a summer (13 May to 31 July 2025) and 65% across a full year (13 May 2025 to 30 April 2026). That is why Swynnerton’s 89% (3 March to 31 May 2026) is our highest figure, a spring window, not a better site, and why we never publish a percentage without its period.
Electricity rates are supplied by each customer and vary from 24p to 30p per kWh, so every £ figure carries the rate it was calculated at.
We never average or total £ savings across sites. kWh and percentages are the comparable metrics. How we calculate a saving.
