Summary of the contracting process

Delta Housing Limited commissioned tree surgery and invasive species management across its estate portfolio in Essex. The tree surgery service covers crown lifting, thinning and reduction, deadwood removal, hazard mitigation, tree felling, stump grinding, and emergency responses to storm-damaged or dangerous trees. The invasive species service covers identifying and mapping species including Japanese knotweed, Himalayan balsam and bamboo, followed by mechanical and chemical control in line with UK regulations, monitoring, follow-up treatments and inspections. This is a public-sector estates and land-management services requirement, combining arboricultural work with environmental and invasive-plant control. The procurement was divided between tree surgery and invasive species services, with both services intended for Delta’s housing estate operations.

The procurement is complete and has been awarded through an open procedure. The award date was 20 July 2026. Tree surgery was awarded to Connick Tree Services Limited and Glendale Countryside Limited for £686,100 gross (£571,750 excluding VAT). Invasive species services were awarded to Japanese Knotweed Limited for £39,744 gross (£33,120 excluding VAT). Both contracts run from 14 September 2026 to 13 September 2029, with an option at Delta’s discretion to extend by up to 24 months, to 13 September 2031. The buyer scheduled contract signature for 31 August 2026. Evaluation for both lots was based on quality weighted at 55% and price at 45%. Eight bids were received for tree surgery and four for invasive species services.

This award demonstrates recurring demand from Delta Housing Limited for two complementary estate-management capabilities: commercial arboriculture and invasive-species control. A credible future competitor would need to deliver tree pruning, felling, stump grinding, hazard mitigation and emergency response, alongside the ability to identify, map, treat and monitor invasive plants using legally compliant methods. The awarded supplier mix shows that both specialist SMEs and larger countryside or land-management businesses can compete: the tree surgery lot was awarded to one SME and one large supplier, while the invasive-species lot went to an SME specialist. The opportunity also attracted substantial SME participation, with five of six final-stage tree-surgery bidders and all four final-stage invasive-species bidders being SMEs. Experience serving housing estates and managing safety-sensitive outdoor work would be commercially relevant.
