In June 2020 I asked thirty two London Boroughs (not including City of London) for information about:

  • their Councillors responsible for weed management
  • their weedkiller policies in particular relating to glyphosate
  • their weedkiller contractors and contracts.  

I’ve had thirty responses to date and I’ve summarised these below. I’ve also given each one an entirely subjective rating for the progressiveness of their approach to weed management from 1 -”doing the bare minimum” to 5 – ”making tangible efforts to stop using weedkiller”. The list below is ordered by rating with the highest at the top. [To be aware, until 7 Jun 2020 I was an employee of Croydon Council]

I haven’t yet received responses from the following Boroughs but if and when I do, I will add them in: Harrow, Waltham Forest.

Hammersmith and Fulham

  • Councillor: Wesley Harcourt – Environment, Parks and Open spaces, and Highways
  • Current weedkiller policy: “All glyphosate weed killers are banned for use in Hammersmith & Fulham on council maintained land, with exceptions for use on Japanese Knotweed and Giant Hogweed.”
  • Weedkiller reduction initiatives: None given
  • Contractors (and contract end dates): Idverde (14 year contract)
  • My rating: 5 out of 5


  • Councillor: Andrew Smith
  • Current weedkiller policy: “Weedkillers and glyphosphate are not used on our roads and pavements and in tree pits. With regards to green spaces including parks and cemeteries the practice is also to not use weedkiller unless there is a very specific weed problem that is hard to eradicate. In the last 3 years less than 10 litres of glyphosphate has been used in parks and open spaces per year.”
  • Weedkiller reduction initiatives: Not applicable
  • Contractors (and contract end dates): Continental Landscapes (contract dates not given)
  • My rating: 4 out of 5


  • Councillor: Jon Burke – Energy, Waste, Transport and Public Realm. Clayeon McKenzie – Housing Services
  • Current weedkiller policy: parks and open spaces – “use glyphosate where absolutely necessary… In 2018/19 this only resulted in us using 25L of glyphosate”, social housing – same policy,  “Streetscene don’t use any chemical control on any of our slip and verge sites or within the tree pit zone. We encourage residents to create tree pit gardens.”
  • Weedkiller reduction initiatives: “A trial weed spraying exclusion zone in the Kings Park Ward, Homerton was introduced in the spring of 2019 the exclusion zone covered 22 Streets and included  land types such as public footpaths, green open spaces, shopping parades, estate housing blocks and low level homes on estates that have significant hard standings. In the Spring 2020 a decision was made to expand the zone for some 70 Streets”
  • Contractors (and contract end dates): Weedfree (annual)
  • My rating: 4 out of 5


  • Councillor: Lead Member for Environment and Neighbourhoods.
  • Current weedkiller policy: “In the past this has been mostly through hand weeding and hoeing, or by using herbicides.  As more has become known about the harm some herbicides can cause to the environment, the emphasis has been on finding alternative methods of weed control and it is now common to see synthetic membranes, dense planting and mulches used to suppress weed growth.  While herbicides may still be useful to deal with persistent weeds such as Japanese knotweed  and bindweed, in many cases weeds can be designed out, perhaps by grassing down infested ground and mowing, or by sealing surfaces.  In Sutton’s parks the Council will adopt an integrated weed management approach using all the techniques available to tackle weeds and only using herbicides as a last resort, to ensure only the absolute minimum of chemical is used… The Council will adopt an integrated weed management approach to weed control and reduce dependence on chemicals by evaluating requirements at each location, designing out weeds, and selecting alternative control methods where appropriate.”
  • Weedkiller reduction initiatives:
  • Contractors (and contract end dates): Idverde (2025), Veolia (2025)

  • Current weedkiller policy:  …”herbicides used in the borough are used on no more than four occasions in any one year, applied by trained, qualified professionals. Chemicals used are generally less toxic than chemicals available to the amateur gardener… glyphosate is routinely used“ .
  • Weedkiller reduction initiatives: Have reviewed alternatives (foamstream, vinegar, hot water, burning, electricity, hand-weeding) and concluded none compete on environmental and/or cost grounds. The council is involved in a pilot working with the Friends of Tower Gardens to declare Tower Gardens a herbicide free area. In this trial the council’s level of resource input is remaining the same and the Friends are increasing their work programme to cope with the hand weeding required” – will be progressed post Lockdown.

  • My rating: 3 out of 5


  • Councillor: Hilary Gander – Portfolio Holder for Environment & Sustainable Transport
  • Current weedkiller policy: “Glyphosate is the dominant method of weed management for Kingston [but]”
  • Weedkiller reduction initiatives: “…this year, we also ran a reduced weed spray trial across the whole Borough. Rather than 3 sprays during the year, we ran 2. We also ran a smaller targeted weed spray trial, where some streets only got 1 spray and another no sprays at all, to understand the impacts of no spraying. We also ran a hot foam trial on one street to assess the effectiveness of this method of managing weed growth… Alternative approaches to managing weeds on the highway are being considered. We are in the process of recommissioning for the Council’s grounds maintenance contract and have discussed with potential contractors to identify current best practice in industry. Through a competitive dialogue process we intend to develop a best-practice approach that minimises the use of weed killer, but that also provides an effective and value for money service.”
