District Heating

District Heating was brought to us in the early 2000’s and we jumped on this when working on various London boroughs across our capital, as we have our very own in-house dig and ground works teams we could do all these works with in TDK and there was no need for outside contractors to aid us or hamper us in our pursuit to complete on time every time.


In 2015 alongside the District Heating division we commenced working on various water schemes throughout the South East with great success working for water providers like Southern Water and Thames water.

Ground Works

Again, alongside both the District heating and utilities we have a full reinstatement team that follows our external team to finish and complete all externals to a high standard.
