Overview

Due to growth, we are currently recruiting for a HIU Engineer on behalf of a fast growing company who design, build and operate 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 £1bn of heat network projects in the coming years.

They need to have experience servicing HIU’s of various manufacturers, and able to fault find and replace parts comfortably. Experience in district heating networks is preferred but not essential.

This is a permanent position, based in London, and is paying £42k – £50k per annum.
