Overview

Due to growth, we are currently recruiting for a Trainee Plumber on behalf of a fast‑growing company that designs, builds and operates district heating networks. This work is for communities, towns, and cities. They work with local authorities, developers, house builders, and property owners.

Operating for over 10 years, they have a number of offices in the UK and also overseas. Their services include the design, installation, maintenance and management of plant rooms and heat networks on behalf of local authorities and property developers.

They are a fast‑growing business who are looking to invest and deliver over £1 bn of heat network projects in the coming years.

The successful candidate will be responsible for delivering operation and maintenance services across the fleet of heat networks. We are looking for someone who is willing to work towards a valid commercial gas certificate, with experience servicing and repairing mechanical equipment. Experience maintaining and operating commercial non‑gas plant, e.g., pumps, valves, strainers, would be beneficial but not essential. The role will be varied, undertaking mechanical PPMs, reactive call‑outs, planned repairs and project work, to further improve reliability and network efficiency across the fleet of networks we operate.

You will be fully supported in the role and will be given a path to help with quick progression.

It is working Monday to Friday, 40 hours per week.

The compact nature of the business and rapid growth means that the candidate has significant opportunity to develop their career in a friendly environment working with and alongside a broadly experienced team of commercial professionals of varying levels. The role does have involvement in an on‑call rota, so the successful candidate will be expected to work on this on‑call rota. Any hours worked whilst on‑call are paid at overtime rates (1.75× hourly rate).

Responsibilities

• Working under the direct supervision of our Technical Manager
• Completion of planned preventative maintenance activities in line with company maintenance schedules (pumps, actuators, plate heat exchangers, pressurisation units, degassers)
• Repair and reinstatement of commercial plant (as per above)
• Completion of fault finding and repairs to commercial plant and other equipment, including pumps and pipework
• Attend reactive call‑outs to sites to reinstate heat and resolve plant failures
• Review root causes for plant failure (resolve operational issues which arise)
• Regularly work autonomously
• Safe isolation of equipment before commencing works
• Good communication with the team always
• Ensure maintenance system records are kept up to date to ensure accurate and secure records. This will involve the completion of clear and concise online work orders.
