Description of risks to contract performance

Specialist energy solutions company with the in-house expertise is required to carry out

multidisciplinary functions, including ensuring all surveys comply with grant

requirements and designing solar photovoltaic installations. Sero’s competency to

carry out the functions referenced has been reviewed and considered

unique as additional to completing engagement activities / Retrofit Assessments / PV

design works, Sero also has the ability to develop and lead on long term asset

maintenance contracts and be a regulated billing provider. As a prototype, the main

project is inherently dependent on Sero’s involvement, requiring Sero to be fully

integrated into the delivery of the principal contract should it proceed to the full Retrofit as Scale (RaS) project.

Procedure

Procedure type

Direct award

Direct award justification

  • Prototypes and development
  • Single supplier - intellectual property or exclusive rights

It is the intention to make a direct award of a contract for specialist preparatory services supporting the Retrofit as Scale (RaS) project to a bespoke contractor Sero without going through a competitive tendering process. This is considered to be required firstly because of the novel pilot nature of the prototype project and secondly because of the urgent nature of the work (given the need to comply with grant conditions).Given the pilot nature of the RaS project it is considered that the proposed contract award to Sero is covered by Section 41.

The RaS pilot involves a model to test and develop the principles as part of a prototype to reduce carbon emissions at scale across our housing stock while providing lower energy costs for residents. The proposed approach is the first of its kind at any significant scale. The proposed approach is the first of its kind at any significant scale.
