As described in the Procurement Documents
- How it runs
This Competitive Flexible Procedure will be conducted in three stages.
Stage 1 - Procurement Specific Questionnaire: Assessment of the Conditions of Participation on a pass / fail basis and scored quality questions to shortlist Participants to be invited to tender. It is intended to shortlist a minimum of 5 and a maximum of 7 Participants per Lot.

- Risks
The Contract may be modified on the materialisation of a known risk within the meaning of section 74 and paragraph 5 of Schedule 8 to the Act. The following risks have been identified for this Contract:
- Awaab's Law came into effect in October 2025 with the law being extended in 2026 and 2027 to address further Housing Health and Safety Rating System hazards.
- There is the ever-present possibility of mergers between Guinness and other housing organisations, which could substantially alter the current property numbers. Whilst there are not currently any such major projects known to the Procurement Team, this is extremely common within our sector and is not outside of the realms of possibility during the Contract Term.
- Property numbers will fluctuate due to property disposal, acquisition, or the development build programme. It is not possible to know how this will impact the property numbers anticipated under this Contract and in turn the impact on the Contract value.
- External factors could also impact upon the scope and associate cost of requirements, due to the introduction of new legislation or regulation. For example changes in law relating to National Insurance and Minimum National Wage which will impact the Supplier's ability to deliver the Contract at the tendered sum and in line with CPI provisions in the Contract. It is not possible to predict any increases in labour costs and the impact on the Contract value.
- Significant shifts in the economy impacting the cost of materials.
- Increase in contract value due to higher than expected replacement heating systems or retrofit requirements.
- Increase in contract value due to higher than expected CPI increases.
- Decrease in contract value due to lower than expected budget allocation.
- Quality of heating systems in properties that are acquired or through merger is unknown could result in a higher than expected requirement to replace the equipment or to retrofit to bring up to a compliant standard.
- The works required to bring the heating systems up to the standards of the Heat Network Regulations is unknown and may be greater than expected.
- Amendments to the Heat Network Regulations could impact on the requirements of the Contract. For example, impact to reportable KPIs to Ofgem, and Guinness KPIs, and implementation of Heat Network Zoning.
- In the instance of contract termination due to continued poor performance, one of the suppliers operating in the other lots will be awarded the contract without re-opening competition.
- The contract has provision to extend the contract for up to a further 10 years. The extensions may be exercised as single years or as two periods of five years.
- The frequency of servicing may change each year based on budget allocation and business performance and may be reduced in year with limited notice.
- The KPIs outlined in Appendix B are subject to change in response to updates in heat network regulations and evolving expectations on Guinness regarding the management of its heat networks.
- Guinness reserves the right to remove water sampling and dosing activities from the contract if Guinness chooses to engage other parties for this work or tender for a dedicated water quality contractor.
- Guinness will review its policies annually. As a result, policies may change during the Contract Term, and new policies may be introduced that will form part of the Contract. This may impact the scope and Total Contract Value.
- Demarcation of responsibility during defect liability period may change during the Contract Term and may include a different approach for each new development. Such as the Contractor only being responsible for in-property servicing and repairs and gas compliance, to all service outlined in the Contract.

- Market engagement18 Aug 2025, 23:59 BST
This market engagement process will be conducted through a questionnaire allowing TGPL to gather input from potential suppliers. This exercise is intended to enhance our understanding of the market's experience and capabilities. The insights gained will help shape the Lotting structure in terms of size and regions of the Lots, pricing mechanisms, conditions of participation and IT requirements.
We reserve the option to have engagement meetings with our incumbent suppliers and also suppliers who may or may not respond to the questionnaire which will further help to shape the approach to our final contract requirements.
If you are interested in taking part in this process, the questionnaire can be found on the Proactis Portal:
