Project summary

With gas and electricity prices reportedly likely to increase by up to 70% year on year, it’s a worrying time for all businesses attempting to keep a lid on expenditure and this is no different for the UK’s leading supermarket, Tesco.

Tesco’s reaction to these reported increases was to employ BIU to double check areas of previous expenditure to recover any overpayment that may have been made to utility companies.

The project consisted of auditing over four years worth of historical electricity supply for nearly 2,000 stores.

The analysis carried out by BIU yielded £425,398 of extra savings to Tesco and in one particular area of investigation alone, BIU secured Tesco’s biggest single supplier refund to data of close to £1/4 Million.

Since engaging BIU’s services Tesco has benefited from savings in excess of £1.2M from a combination of invoice processing and a capacity reduction scheme. This is just the icing on the cake as BIU manage and process all Tesco stores utility invoices and resolve all the queries.
