It’s the boring stuff, post installation, trawling through utility bills and comparing the twelve months prior to installation with the inaugural twelve months under the new regime, the acid test, the definitive yard stick, has the payback been achieved? Was it worth all the money? This is where we excel. We’ve been doing it one way or another for a very long time. It’s our stock in trade and your guarantee that we will meet our pledge.
