ECK Civil Engineering worked as the main subcontractor, to deliver both groundworks and pipework elements of a large ground source heat project, to convert the majority of St Alexandra and Albert School heating system from existing ageing oil boiler systems, to new heat pump systems. The site is within 260 acres of Capability Brown landscape, with Grade II Gatton Hall at its centre. It is said to be the largest ground source heat pump project in a school in the UK.

In total 18 buildings where converted from oil boilers to heat pumps, in a bid to reduce the carbon footprint of the school by nearly 70%. The total installed capacity of all the ground source heat pumps combined was in the region of 2MW, and replaces cica ~750,000l of oil usage per year.

Overall, ECK installed over 25000m of Pipework, ranging from 160mm flow and return pipework, to 40mm borehole and collector loops, several of which were excavated and installed working alongside the onsite archaeologist, to ensure the history of the site was preserved.
