Network Engineer

Utility Warehouse is a FTSE 250 organisation which has established itself as the most trusted supplier of utility products in the UK. Utility Warehouse is the only genuine multi-utility operator in the market providing gas, electricity, landline, broadband, mobile & insurance products and services to households and businesses nationwide, all on one single monthly bill. With over 600,000 customers the organisation has grown through a philosophy of offering savings, simplicity and service. Customers enjoy a number of advantages, including membership of a discount club, and a unique CashBack reward system on everyday shopping. The organisation does not advertise, preferring instead to invest in customer services and to keep prices low. Utility Warehouse has predominantly grown through a network of over 45,000 partners who operate as lead generators and advocates for the organisation. These partners come from a range of personal and professional backgrounds, and actively take it upon themselves to promote and recommend Utility Warehouse to friends, families and their professional networks. Trust between these partners and the organisation is crucial, and ensures that customer service and satisfaction are consistently prioritised.

The company was founded in 1996 with the mission of disrupting the domination of the small number of major energy suppliers by prioritising world-class relationship building with customers. Utility Warehouse is the only fully integrated supplier of telecoms and energy services which allows them to achieve unparalleled operating efficiencies as well as a breadth of revenue streams. Company revenues have grown to an excess of £740 million and the business employs over 1000 individuals. Almost all staff are based at their headquarters in Colindale, London.


Utility Warehouse is an energetic and entrepreneurial challenger in a market traditionally composed of monolithic, slow competitors. In the utilities market, it is difficult to compete on the quality of the product and therefore establishing a strong value proposition is crucial to avoid a race to the bottom on price. Utility Warehouse has established itself as the most trusted brand in its sector, winning accolades from industry publications and consumer advisory guides. Customer service is at the core of their business ethos and another way they differentiate from their competitors; 93% of customers would recommend the organisation to a friend. By establishing a best-in-class experience for the consumer, Utility Warehouse commands a strong market position in an age where technology makes it increasingly easy to access information on consumers’ experiences. The organisation is well-placed to capture an increasingly large portion of the £52bn market that they operate in. By staying true to their values of trust and service, Utility Warehouse is the only major provider in the market to be both growing and profitable.

Utility Warehouse has an adaptive, agile, fast-paced culture which has enabled it to grow rapidly. The management team has expanded over the last two years as part of the growth strategy with significant hires in technology, legal, marketing, and finance. These hires and the rebuilding of the platform will enable the company to grow to two million customers over the medium-term. Utility Warehouse operates at high-transactional scale, processing large volumes of data. This presents new opportunities to understand customer behaviours better and to create an improved customer experience as a result.


The Systems and Network team ensure that the underlying infrastructure that the business relies on is reliable, stable and has the capacity for future changes required by the business.
The team is small but highly multifunctional. There is nothing that is "not our job" and there is no tech "we don't know", we just haven't looked it up yet. We strongly believe in infrastructure as code and value correctness, simplicity and performance. Lastly, we love to challenge conventions, just because others are using something, it doesn't mean we will.
