170 (Infrastructure Support) Engineer Group was an engineering group of the British Army's Corps of Royal Engineers.
It was disbanded in 2023 with all subordinate units moving to 12 (Force Support) Engineer Group.
In 1978, following the 1975 Mason Review, the Military Works Force was formed at Chetwynd Barracks to control the Corps of Royal Engineers's works groups. It controlled the specialist engineering units and helped in commanding and providing those special services. The group was originally formed with the control of just two Commanders Royal Engineers (CREs) each with three Specialist Teams Royal Engineers (STREs), but this force was later expanded.

In 2003, the 2003 Delivering Security in a Changing World reforms were announced.

Following the initial Army 2020 reforms, each works group control a reserve specialist team regularly, as opposed to randomly for deployments. Following these initial reforms, the group was due to take control of the Royal Monmouthshire Militia, but this was reverted in 2015 when the refine announced they were to move under control of Headquarters Royal Engineers, 3rd (United Kingdom) Division.[4]
In 2015, the Army 2020 Refine was published, as an "updated chapter" to the initial Army 2020 reform. Under this refine, the group HQ is to move to Gamecock Barracks, and is also due to have a decrease of 9 personnel.[5]
Following the reform, the group now has the following structure;[6]
