The £20m contract is a retention of five shopping centres managed by NG Bailey for the last five years and plus a further three centres.

NG Bailey will provide mechanical, electrical and building fabric maintenance, including HVAC, security, fire detection and protection, drainage and energy consumption management.

Seven of the shopping centres will be maintained by resident NG Bailey staff while a smaller centre in West London will be serviced and supported by the firm’s fleet of mobile engineers.

Stuart Linington, managing director of NG Bailey’s Facilities Services division said: “We’re delighted to have been awarded this significant contract, which builds on the strength of our existing relationship with Land Securities.

“As part of the new contract, we proposed an innovative energy saving solution that will introduce significant savings and further improve Land Securities’ impressive sustainability record.”

Tony Hemmings, Head of Engineering at Land Securities, added: “NG Bailey has proven that they can exceed our expectations, while being cost-effective and delivering measurable results.

“We are pleased to be working with the company for another three years, potentially six and, to have added three more centres to its remit.”
