The benefits that are obtainable from a programme will vary according to the type of organisation, the amount of work it has already done in the past to improve energy performance and the level of investment they are willing to make in more efficient technologies.

However, the UK Government estimates that the average organisation wastes 20% to 25% of the energy it purchases so that is perhaps a good rough guide to what might be achieved.

Our own experience suggests that, for a typical organisation that has done little in the way of energy improvement, it would be reasonable to expect that about 15% improvement could be achieved with little investment and 25% or more with a reasonable investment (e.g. a 2 year pay back).
