More than 200 suppliers attended a DIO event last week to discuss work opportunities under the deals.

Gill Hodson, senior Next Generation Estate Contracts (NGEC) project manager, said: “During this period of fundamental change for UK Defence we are determined that businesses with an interest in these three major contracts have a coherent understanding of the challenges and issues for our future industry partners.

“I am delighted that such a wide range of businesses were able to attend and engage in the networking session.

“This is the outset of procurement for these significant regional arrangements, and we would now urge other smaller businesses with estate solutions – from low carbon technology and roads maintenance to plumbing, roofing and pest control – to consider where they might contribute and then to make contact with those seeking prime contracting roles.”
