About Hemiko
Hemiko is a fast-growing innovative business which is looking to invest in and deliver over £1bn of heat network projects in the coming years. We fund, design, build, operates and maintain low carbon district energy networks and building energy systems. This work is for communities, towns, and cities. We work with local authorities, developers, house builders, and property owners.
We are looking to lead on town and city scale decarbonisation. We recognise that the decarbonisation of heating and the built environment is one of the least known and “solution clear” areas - this is where we are focused and where we will be deploying our investment and our resource.
We are an innovative, design and proactive intelligence led company, looking to attract people who think around a problem and past an issue. We want to be at the front end of commercial and technical innovation and are looking for team members to come on that journey.
Some of our current projects include:
- The design, installation, operating, and funding of a district heating system to serve 3,500 homes in Clapham as part of a major regeneration project.
- The design, installation, and operation of a new city centre wide low carbon district heating system for the City of Cardiff.
- The design, installation, and operation of a ground source heat pump system to provide heating and cooling to a new development of 300 homes a gym and office building in South London.
- The design and installation of a heat network in a rural community in Cambridgeshire to replace oil boilers in 300 homes with centralised low carbon heat generation.
- Developing detailed long-term decarbonisation plans for existing large scale district heating networks to allow them to transition from gas fired CHP led generation to low carbon generation.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
