Although most of us might think of it as synonymous with pest control, £2.4bn-turnover company Rentokil Initial is actually a huge group that extends from washroom facilities to office art and plants via parcel delivery services.

Under Bryan Kinsella, the firm has embarked on a massive IT project to consolidate and align what was a piecemeal setup. Networks, telephony, datacentres, groupware and applications have been rationalised and handheld devices have been distributed to customer-facing staff. In the process, Rentokil Initial said it had realised significant savings on software licences.

Most significant of all, perhaps, Rentokil Initial made headlines the world over when it announced in October that it was to begin rolling out Google Apps to up to 35,000 users, primarily for email. The deal was the biggest paid-for implementation of Apps in Google's history.

Kinsella has also set up a project management framework to bring rigour to the company's plans with intranet-based training, videos and how-to tools. To encourage his "junior CIOs" Kinsella has also placed IT representation on the executive boards of Rentokil Initial divisions.
