UNDERSTANDING B ILLS
Do you ?Ltr, M³, kWh, kVa, MIC, MDLV, Tuos, Duos….. Cost vs Consumption – what do you control?Penalties, surcharges, excesses – do you haveany? Why?Oil, LPG, Mains/Natural Gas – ok - !Gas!
Electricity – very difficult – no explanations onwebsites – very poor service

UNDERSTAND B ILLS
All EnergyAverage Unit Price –– Divide total bill (net of VAT) by total units (Day+Night) =
AUP – then c o m p a r e with similar size business
Actual or Estimated – make sure you notify monthly
Can you access on-line meter readings – examine consumption – especially when closed
Get supplier to explain your bill to you – in detail and theelements you can manage

MONITOR C ONSUMPTION
You cannot Manage if you don’t Measure
What do you currently measure ?
Energy ? Waste ? Water ?
Minimum Monthly, better weekly – better on-line
What about sub-metering – 20%

HAVE A P LAN
Don‟t leave it to chance One off campaigns lose their effectivenessIf it‟s not written down, it won‟t happen
Keep it simple – keep it short – make sure its attainableResource it – time is the key resourceFocus on no/low cost
