Ipsum
At Ipsum, we provide specialist infrastructure services across the UK’s regulated water and energy companies and private sector businesses. We work with our customers to maintain, optimise and develop their above and below ground assets to ensure security and resilience, and with our smart systems and ways of working, we ensure we deliver on time, on budget and safely. At Ipsum, we develop long-term working relationships with our customers by providing essential utility services on both public and private networks. We have many long-term contracts and framework arrangements in place which are built upon great customer service, safe working practices and the ability to flex and deploy specialist skillsets at short notice. The growth of Ipsum has been built upon our people and our ability to meet the demanding and ever-changing needs of our customers. The UK utility sector is evolving and expanding to meet increasing customer demand, regulatory-driven outcomes and to exploit new innovative technologies, at Ipsum we will continue to grow in this sector by being a reliable, flexible and agile service partner that helps customers meet these new challenges. As we know, utility service provision is not a 9 to 5 business, our customers don’t switch off their networks or assets at night, or at the weekends, or on holidays, or when things are quiet. They need them to work round the clock – and we at Ipsum are right beside them 24/7 to make sure they do. We pride ourselves in providing specialist scheduled maintenance services, being able to respond to an individual call-out or mobilise onto a major upgrade project and that our customers can rely on Ipsum 24/7/365.
