EXPLANATORY NOTE
(This note is not part of the Regulations)
These Regulations amend the Single Source Contract Regulations 2014 (S.I. 2014/3337, amended
by S.I. 2024/420) (the “2014 Regulations”).
Regulation 2 amends regulation 11 of the 2014 Regulations, which sets out the steps to be followed
by the Secretary of State in determining a contract profit rate for a qualifying defence contract under
those Regulations. Regulation 2 amends regulation 11 to raise the permissible incentive adjustment
from two to ten percentage points. It further amends regulation 11 such that the incentive adjustment
may only be used in respect of outcomes which are objectively verifiable, and which relate to
relevant provisions of the contract in question.
Regulation 3 amends regulation 51 of the 2014 Regulations in order to add the determination of an
incentive adjustment to the list of matters on which the Single Source Regulations Office is required
to give an opinion on a reference made to it by a person mentioned in section 35(2) of the Defence
Reform Act 2014.
Regulation 4 amends regulation 65 of the 2014 Regulations, so that for qualifying sub-contracts the
permissible incentive adjustment remains at two percentage points, and continues to be determined
by the contracting authority.
