Some of the deepest boreholes in London are set to be drilled underneath the city to install ground source heat pumps.

The plans include sixty 240-metre-deep boreholes, which will form a closed-loop system, as part of a £300 million development of Salisbury Square. The hope is that this will power a new civic hub for the Square Mile.
