AHDB is firmly committed to openness, fairness and transparency in selecting all of its suppliers of goods and services. It must do this as a matter of law under the Public Contracts Regulations 2015, and this approach will also enable us to develop a ‘most economically advantageous’ supply system and maximise our use of levy funds.

Please click here for AHDB's Terms and Conditions.

AHDB has a template for its contract for the purchase of goods and services. AHDB also has templates for Research Funding Agreements (two party and multi party). These may be updated at any time by publication on this website and contracts are made applying the version current at the time of contracting. Suppliers are responsible for keeping themselves aware of changes. The current version applies from August 2015. Previous versions can be obtained on request to the Legal Adviser at



AHDB publishes contract opportunities over 25,000 on Contracts Finder. This is where suppliers can search for contract information on goods and services across the public sector. Suppliers are encouraged to register on Contracts Finder:

Current opportunities on Contracts Finder


Contract opportunities may also be advertised in the Official Journal of the European Union (OJEU) if the contract value exceeds financial thresholds (currently 173,000).

However research and development (R&D) opportunities do not always have to be advertised in this way and may be found below.


Optimising the Use of Antimicrobials: Preparing the Industry for in-water delivery in the short term and improving hygiene and more effectively targeting medication in the longer term

The overall aim and objectives are to conduct a desk study to prepare the pig industry for a move away from in-feed medication by 2020 by developing a template for an effective on-farm water supply system to maintain good health and welfare of stock and in order to be able to more effectively deliver antibiotics in a more targeted way at individual pig or pen level

A desk-top study is being commissionedby AHDB Pork to prepare producers for an anticipated change in legislation during 2017 to move from in-feed to in-water medication within three years.

AHDB Potatoes Research Call ? Integrating Potato Agronomy and Storage

Industry priorities relating to agronomy and storage continue to be recognised by AHDB Potatoes and are incorporated into the Research and Innovation Strategy (2015-2020). A requirement was identified for an integrated programme of research which further explores the relationships between agronomy regimes and the implications for storage and the tuber quality delivered to the end user. It was also recognised that there was not always sufficient empirical information on field agronomy and environmental variables that may be able to inform storage practice and storage potential, or that may retrospectively provide evidence to explain storage issues.

The aim of this call is to commission integrative, outcome focussed, agronomy and storage research which address the following priorities:

  • The impact of seed storage practices on the performance of the daughter crop/quality of daughter tubers to meet end-user requirements.
  • The impact of field agronomy/environmental factors on the incidence of physiological conditions e.g. blackheart, and dormancy and sprouting.
  • The impact of field agronomy/environmental factors on the resilience to storage disease.
  • Review of information on chitting technology, including LED lighting, which might be more effective and reduce the cost of chitting.

05 May 2016 - AHDB Horticulture Cross Panel Research and Development and Knowledge Transfer Call for Proposals: Chlorate and Perchlorate Review

Purpose/Primary Objective Scope

The primary objective is to undertake a chlorate & perchlorate literature review focusing on the sources and fate of plant absorbed chlorine in horticultural produce and in potatoes.

i. Sources ? where and how is chlorine taken up (e.g. treated/untreated irrigation and produce wash water; growing media; different soils and their holding capacities; feed mixes)? What forms/ions are taken up? An understanding of root zone/in solution chlorine chemistry is essential.

ii. Fate ? how and where are chlorine ions assimilated, bioaccumulated and metabolised within the plant? How is chlorine partitioned during growth? What percentage of the ‘input’ chlorine ions/compounds end up as chlorate and perchlorate in the final horticultural product that is ready for harvest / what percentage is taken up during horticultural produce and potato washing?

The use of hydrogen peroxide for water treatment should also be reviewed.


The chlorine compounds chlorine dioxide (ClO2), sodium hypochlorite (NaClO), calcium hypochlorite (Ca(ClO)2) and to a lesser extent chlorine gas (Cl2), are used during crop production to disinfect waters used for irrigation and the postharvest washing of fresh produce and potatoes destined for packing and further processing. In addition chlorine compounds are used for cleaning and/or disinfecting machinery and equipment used at harvest and postharvest.

The aim of this review is to help levy payers to identify actions that they can undertake to mitigate against chlorate and perchlorate exceedances in edible fresh produce and in washed raw potatoes destined for packing or further processing. The review will also inform AHDB Reseach & Development and/or Knowledge Exchange work going forwards.

i. The review should cover the different chlorination systems (and practices within systems e.g. ClO2 systems and dosing strategies) and impacts on chlorine oxides’ chemistry in the root zone/in solution. It should include but not be limited to the following:

  • Chlorine chemistry as relevant to horticultural produce production. Should capture pre-harvest, harvest and postharvest chlorine entry points into fresh produce.
  • With regards to dose rates, can the chlorate/perchlorate uptake be reduced whilst preserving the microbial integrity of produce? Can one manipulate or reduce the amount of chlorate/perchlorate in stock solutions before/at the point of use?
  • Do different plant parts accumulate different amounts of chlorate/perchlorate from the same chlorination system?
  • How is chlorate/perchlorate partitioned/bioaccumulated within edible horticultural plants during growth?
  • Are there differences in bioaccumulation rates between different edible crops?
  • How much is taken up during the postharvest washing of edible horticultural produce and potatoes?

The deadline for receipt of submissions is 17 June 2016.
