Invitation to Tender: Tree Equity and Urban Resilience Project
About the project
Trees for Cities is delighted to support the Mayor of London, Sadiq Khan's new London Tree Equity and Urban Resilience (TE&UR) project a grant-funded partnership scheme initiated by the Greater London Authority (GLA) to improve access to trees, and the benefits they provide, within London neighbourhoods facing high heat risk and wider social vulnerability. We'll be engaging Londoners in target boroughs to help plant and care for more trees where they're needed most.
As part of our role in this project, we are inviting bids from suitably qualified consultants to support delivery of the Tree Equity and Urban Resilience (TE&UR) initiative.
Trees for Cities is acting as the contracting authority for this commission and will oversee delivery of the consultant’s work as part of the wider TE&UR partnership.

FAQs
Please submit clarification questions via this online form.
Responses will be uploaded regularly to this webpage.
Deadline for submission: 15/07/2026
Can you confirm the level of technical support provided by Royal Botanical Gardens and Shade the UK, specifically how this input relates to the tasks set out in the brief?
The level of technical support from these partners is specified in days that can be drawn on, and through specific workstreams and phases they will contribute to throughout the project. Both have toolkits and existing methodologies that can be drawn on by agreement to support the work.
Can you confirm there is no community engagement requirements as part of the ground-truthing 2 task? Can you confirm whether consultants should allow for any attendance at community engagement activities led by TfC?
All community engagement will be led by Trees for Cities; your role will be to work closely with us to ensure our engagement staff have all the information they need for meaningful community input. There may be times when it would be helpful to have a representative join an engagement activity, and when TfC staff need to join ground-truthing activities.
The ITT states that, at a minimum, the bidder should allow for:
- Fortnightly 45-min coordination meetings with TfC
- Participation in 10 monthly TE&UR Delivery Group meetings involving all partners involved in the initiative, including borough representatives
- Contribution to at least one key project workshops per ward (e.g. 15 workshops)
It is assumed that a quantity surveyor is not required as part of the consultant team and that estimated/indicative costings are sufficient. Please confirm.
Correct.
Question 3 requires the inclusion of a team organogram. As it’s a diagram, can the organogram be provided in addition to the three-page limit (as per the approach to the CVs)?
Yes.
Section 1.2.5 states that the project programme stretches from mid-August 2026 to December 2027. However, the process diagram on page 12 of the brief appears to show the investment planning element delivered by the consultant continuing into 2028 and running concurrently with the 27-28 planting season. Please confirm if we should therefore assume a March 2028 end date.
We agree that it would make sense for this contract to continue until March 2028 alongside the rest of the project.
It is assumed that the conceptual design element of the treescape investment plans will not require the purchase of topographical mapping in relation to the priority pilot schemes. Please confirm.
If we need topographical surveys of the 10-12 sites targeted for pilot schemes, this can be funded from a separate budget.
Would the client accept some minor wording changes to the Ts and Cs to ensure alignment with our insurance?
Yes, we can discuss the Terms and Conditions of contract following award of the opportunity and will do our best to accommodate changes where possible.
Is there guidance on the level of Professional and Public Liability Insurance required?
To match our own level, Public Liability £10 million and Professional indemnity £1 million.
Please confirm the format of the outputs of the community engagement (led by TfC), mentioned on page 13.
From the ITT
e. Consolidation of community shaped opportunities
Use outputs from community engagement (led by TfC) to refine and shape priority opportunities:
- Group mapped and ground-truthed opportunities into street‑, block‑ or micro-area packages that reflect how communities experience places and have expressed priorities.
- Document, at a proportionate level, why each opportunity package matters, the needs it addresses (e.g. heat, equity, wellbeing), and how community input has helped shape the proposed approach.
As TfC engagement staff work with residents to identify the “desireability” of opportunities alongside the “deliverability”, there will be findings relating to context, historic use, and community support that need to be fed back to shape priority opportunities.
The form of these outputs is something that can be negotiated between the consultancy and Trees for Cities as we develop the project together following award of the tender. Our priority is to work closely together to ensure you have the data you need in the most useful format we can provide.
Please confirm whether TfC will provide access to an existing GIS platform or whether bidders should assume responsibility for providing all software, licensing, hosting, and user access required for project delivery and stakeholder collaboration.
Bidders should expect to use their own software for project delivery.
What are the expectations regarding hosting and ownership of GIS applications and data after project completion? Please clarify the expected long-term hosting and ownership model for GIS datasets, web applications, survey tools, and engagement platforms created through this commission. Should these be delivered into a TfC-managed environment or as standalone deliverables?
Bidders should ensure that all project data, applications and associated outputs are fully transferable to project partners at project completion and should not rely on ongoing supplier-hosted solutions, unless perpetual, royalty-free license to use can be granted to the Greater London Authority and other partners associated with the Tree Equity and Urban Resilience initiative.
The primary long-term users of the opportunity mapping outputs will be the participating London boroughs. Consultants should therefore assume that datasets will need to be compatible with borough GIS and, more importantly, tree management systems (such as Confirm, Ezytreev or equivalent platforms), rather than requiring continued use of bespoke standalone applications.
The project aims to create a reusable legacy. Accordingly, datasets, survey tools, workflows, scripts, methodologies and other digital outputs should be supplied in documented, accessible and reusable formats that can be maintained and adapted by project partners after completion of the commission.
Any personal data collected through the commission must be managed in accordance with UK GDPR and relevant data protection legislation, and all project outputs must be capable of being transferred to the relevant project partners at project completion.
For the interactive GIS-based engagement tools referenced in the specification, please clarify the anticipated scale of use, including expected numbers of borough users, partner users, and members of the public, together with any requirements for authenticated versus anonymous participation.
At present we don’t have expected numbers of members of the public to be engaged, due to the stage of planning of the project and the fact that wards and sites have not yet been confirmed. We know that the approach will be localised for each ward based on opportunity mapping, which may mean engaging with residents in one specific block, street, or group of streets, so we wouldn’t anticipate large scale use. TfC will work closely with the awarded agency to plan the best methods of engagement for specific sites, which may be non-digital.
The specification refers to community engagement tools and online submission of comments. Are there any information governance, GDPR, accessibility, cyber security, or hosting requirements that bidders should assume when proposing digital engagement solutions?
Any proposed digital engagement solutions should comply with UK GDPR and the Data Protection Act 2018. Suppliers should have appropriate cyber security controls and ensure any personal data collected through engagement activities is managed in accordance with data protection requirements.
Definition of "ward": Please confirm how "ward" is defined for this commission. Specifically, will the 15 wards be based on electoral wards, or on another administrative or statistical geography like ONS wards?
The 15 focus wards are currently being discussed with borough partners and will be confirmed as soon as possible; hopefully by the time this contract is awarded. These will be electoral wards.
Intended end users of the reusable digital outputs: Who is expected to be the primary user of the reusable GIS workflows, scripts and templates? Understanding this will help us confirm which GIS software the outputs need to be compatible with, so that boroughs and partners can readily use them beyond the commission.
The primary intended end users are local authorities and members of the London Urban Forest Partnership; organisations who might wish to build on the work of this project to address tree equity in other areas.
Distinction between fixed and ward-based costs: Please could you clarify how costs should be categorised in the commercial submission. For example, we understand that opportunity mapping could be treated as a fixed cost. Could you confirm what should be classed as ward-based costs, and where the distinction lies between the two?
Some costs will be fixed such as project mobilisation. However, all work relating to the mapping, which includes the desktop mapping, ground-truthing visits, interaction with Trees for Cities’ engagement team, and investment planning, will be ward-specific.
We are not prescribing how bidders must allocate costs. The purpose of the breakdown is to help us understand which costs would remain broadly unchanged if the number of wards were reduced or increased, and which costs scale with the number of wards.
Supporting project examples: In addition to the CVs, may we also include short project sheets in our appendix to illustrate our relevant experience?
Yes.
