Supporting a district heating network serving approximately 25,000 residents, the role is focused on ensuring customers have reliable heating and hot water within their homes.\nThe position combines planned servicing with reactive fault-finding, requiring engineers to diagnose and repair a wide range of heating system issues including HIUs, radiators, thermostats, motorised valves and heating controls. Engineers are expected to be comfortable working on S-Plan and Y-Plan systems and have a good understanding of low temperature hot water (LTHW) heating systems.\nWhilst the role is primarily resident-facing, candidates should also have a basic understanding of district heating infrastructure and energy centres. HIU Engineers are often the first responder to heating outages and should be capable of carrying out initial diagnostics, identifying whether faults originate from the HIU, heating system or energy centre, and escalating plant-related issues where necessary.\nTypical workloads include servicing 8-10 HIUs per day or attending 6-8 reactive heating and hot water breakdowns. Engineers participate in a 1-in-4 emergency call-out rota covering London and the surrounding areas alongside other HIU and Plant Engineers.\nThis role is ideal for experienced domestic or communal heating engineers looking to specialise within the growing district heating sector.\nKey responsibilities\nCompleting scheduled servicing of Heat Interface Units in accordance with the servicing procedure\nProviding reactive maintenance for loss of services within required Service Level Agreements\nIdentification and review of equipment faults carrying out repairs where required\nInputting and maintaining documentation and records using the company asset management software\nCarrying out general ad hoc maintenance tasks within Energy Centre Plantrooms\nWorking in a safe manner and in accordance with the company’s Health & Safety policy\nWhat you will need\nHold a city & guilds qualification or equivalent\nPreferably educated to Degree level\nExperience wiring and fixing, Boilers/Heating, HVAC, Steam, Air Handling, Cooling, Renewable Energy (e.g Solar or Heat Pumps), or similar\nFull UK manual driving licence\nThe Company\nVital Energi is a major provider of renewable energy infrastructure and systems to the public and private sectors.
