Evaluation of the Energy Savings Opportunity Scheme (ESOS)

Modification Notice

Original description: DECC was looking for a contractor or consortia to undertake a full evaluation of the Energy Savings Opportunity Scheme (ESOS). This invitation was to tender for the evaluation activity required between early 2015 and December 2016. Further activity may be commissioned in an additional phase from Jan-2017 to mid-2019. The evaluation work will need to address key evaluation questions identified in the invitation to tender and evaluation activities required from the contractor are expected to include new qualitative and quantitative data collection, qualitative and quantitative analysis, and a synthesis of evidence from all strands.

Description of the modifications

The original value of the contract was £260,580. The contract was varied to include an additional £12,500 of work, in order to expand the length of the surveys conducted as part of the original ESOS evaluation by an additional 5 minutes per questionnaire. This was done to ensure that the data collected is comprehensive and covers all of the additional questions scoped in phase 1 of the evaluation. the totoal value of the contract is now £273,080. The length of the contract is unchanged.

Description of the circumstances which rendered the modification necessary and explanation of the unforeseen nature of these circumstances:

The contract value was increased by £12,500, to allow for a longer survey component of the research. This is because the context of the research has changed 1) as the policy has been implemented (compliance deadline was 5 December 2015), the number of complying/non-complying organisations is now different to that expected in the ITT and this could not have been foreseen, 2) the scoping phase of the evaluation has uncovered additional groups to be interviewed and questions to be asked.
