As described in the Procurement Documents

Description of risks to contract performance

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:

1. 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. Tenderers must therefore comply with Guinness requirements for complying with Awaab's Law in its current and all future versions, including but not limited to reactive timescales and assessing risks at the start and end of visits, using Guinness' risk criteria.

2. 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.

3. 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.

4. 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.

5. Significant shifts in the economy impacting the cost of materials.

6. Increase in contract value due to higher than expected replacement heating systems or retrofit requirements.

7. Increase in contract value due to higher than expected CPI increases.

8. Decrease in contract value due to lower than expected budget allocation.

9. Quality of 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.

10. 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.

11. 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.

12. The frequency of servicing may change each year based on budget allocation and business performance and may be reduced in year with limited notice.

13. Guinness may undertake capital investment programmes for certain equipment types, such as CCTV equipment, that changes the nature of servicing, repairs and maintenance and contracts will be expected to adapt to any new servicing type accordingly. This may require a modified pricing structure and specification of requirements for those equipment types.

13. The KPIs outlined in the procurement documents are subject to change in response to updates in relevant regulations and evolving expectations on Guinness regarding the management of its systems.

14. Guinness reserves the right not to mobilise and commence the renewables element of the service depending on its confidence in the successful tenderer's ability to sufficiently manage this workstream.

15. 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.

16. Demarcation of responsibility during any defect liability periods may change during the Contract Term and may include a different approach for each new development.

17. Guinness may undertake capital investment programmes for certain equipment types, such as CCTV equipment, that changes the nature of servicing, repairs and maintenance and contracts of that asset types. Contractors will be expected to adapt to any new servicing type accordingly. This may require a modified pricing structure and specification of requirements for those equipment types.

Procedure

Procedure type

Competitive flexible procedure

Competitive flexible procedure description

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 4 Participants per Lot.

Stage 2 - Invitation to Tender: Assessment of scored quality questions and pricing submission. Quality questions will be weighted at 60% and pricing weighted at 40%. Further details are provided in the Procurement Documents.

As part of stage two, Guinness will invite the top 3 highest ranked supplier for each lot to present their answers to the a resident focussed Question to a Resident Panel.

As a result of these presentations, final moderation will be limited to no more than a point either way (up or down). If the moderated score causes one of the top 3 to drop to top 4, the next bidder will be brought forward for a presentation and moderation.

Stage 3 - TGP will also reserve the right to conduct a Negotiation stage, following the evaluation of quality and price. It is proposed to down select suppliers and only invite the highest ranked suppliers for each lot to participate in negotiations if a supplier wins multiple lots. TGP will reserve the right not to award multiple lots to the same supplier if the bidder fails to provide reassurance of their capacity to delivery multiple lots during the negotiation stage.

The purpose of the negotiation would be to ensure that any supplier winning multiple lots has got the capacity to deliver the combined lots and that any economy of scales are taking into account.

It is the intention to appoint a minimum of two suppliers. This will be achieved by restricting the number of lots a supplier can win to a maximum of two lots for M&E, and all lots for Water. Bidders submitting a tender for more than one lot will be asked to rank their preferences with regard to the lots to be awarded.

Justification for not publishing a preliminary market engagement notice

This tender is the second version of the previously terminated "Mechanical, Electrical and Plumbing Service and Capital Works" tender, Procurement identifier (OCID): ocds-h6vhtk-05d0c5.

As this tender is a continuation of that project, no further market engagement was deemed necessary and therefore a PMEN was not published for this second version.
