Here is what the data is showing for property owners on the Isle of Wight and beyond. Enquiries for residential knotweed surveys have risen sharply over the first quarter of 2026, with specialist contractors across southern England reporting backlogs into early summer. The Isle of Wight has followed the same pattern, driven by mild winter conditions, increased mortgage activity, and a wave of properties coming to market that had previously been delayed by buyers waiting on interest rate cuts. ## Why the spike is happening now Three factors are converging. First, the unusually warm February gave Reynoutria japonica an early start, with red asparagus-like shoots appearing in coastal pockets near Ryde and Cowes by mid-March. Second, the housing market is moving again, which means more conveyancing surveys and more TA6 disclosure questions being answered honestly for the first time. Third, lenders are tightening their position on properties within seven metres of an active stand, pushing sellers to commission management plans far earlier in the sale process. ## What it means for treatment costs Pricing has stayed broadly stable compared with 2025, but homeowners who delay risk paying a premium for emergency mid-season visits. The most cost-effective bookings continue to be those scheduled before the first foliar herbicide window in late June. We are also seeing higher demand for excavation and on-site burial where development timelines do not allow a multi-year herbicide programme. ## Outlook for the rest of the year Expect continued pressure on availability through August. Properties in semi-rural parishes such as Wootton, Brading, and Niton are particularly affected because of established roadside infestations. Booking a survey early in the season remains the single best way to keep options open and avoid forced compromises during a property sale. ## Key Takeaways - Q1 2026 has seen a notable rise in survey enquiries across southern England - Mild winter conditions brought knotweed shoots out earlier than usual on the Isle of Wight - Lenders are scrutinising the seven-metre rule more strictly during conveyancing - Booking before late June secures the best treatment windows and pricing ## Concerned About Knotweed on Your Property?
