Market engagement runs in two stages: an online webinar on 25 November and one-to-one interviews from 7 to 18 December, then a second stage in spring 2027. A tender notice with full documentation is anticipated in the third quarter of 2027.
In energy and environment work, Hounslow has previously contracted Recycle 360 for £78.0 million and Dennis Eagle for £5.48 million, in GovMarket records.
