Statutory guidance

Recommendation factsheet 2024

Published 18 March 2024

Under the Defence Reform Act 2014, the SSRO must provide the Secretary of State with its assessment of the appropriate rates used to determine the contract profit rate for pricing qualifying defence contracts and qualifying sub-contracts. For further information on the methodology used to calculate these rates please see the Single source baseline profit rate and capital servicing rates methodology.

Baseline Profit Rate

The baseline profit rate is step 1 of the four-step process for determining the contract profit rate for a qualifying defence contract.

From 01 April 2024, this replaces the previous six-step process.

The baseline profit rate is calculated from an index of public and private companies. The rate is a composite that combines search results from the “Develop and Make” and “Provide and Maintain” activity groups. The underlying rate is the average of the median capital servicing adjusted profit on cost of production of each group. The baseline profit rate is the rolling average of the underlying rate.

Capital servicing rates

The capital servicing rates are used as part of the Step 4 Capital Servicing Adjustment (CSA) of the four-step process for determining the contract profit rate for a qualifying defence contract. A corresponding adjustment accounts, at an aggregate level, for different levels of capital employed across the companies in the index and so sets a baseline upon which Step 4 of the contract profit rate applies.

The capital servicing rates are calculated from indices of sterling denominated corporate bonds or fixed maturity deposits. The rates are rolling averages of the underlying rates.

2020/21 2021/22 2022/23* 2023/24 2024/25
Fixed capital servicing rate 3.66% 3.27% 2.87% 2.90% 3.26%
Positive working capital servicing rate 1.22% 1.33% 1.09% 1.67% 3.10%
Negative working capital servicing rate 0.61% 0.65% 0.51% 0.51% 1.61%

‘*’ Shown are the 2022/23 rates recommended by the SSRO. The Secretary of State determined the BPR for 2022/23 as an average of the composite underlying rates calculated by the SSRO for the three years prior to 2021 (8.50%, 8.23%, and 8.19%), keeping the BPR at 8.31 per cent. This fixed the capital servicing rates the same as for 2021/22.

Data sources

For further information on the data selection approach please see section 13 of the Single source baseline profit rate and capital servicing rates methodology.

Rate Description
Fixed capital servicing rate Seven-year average of ’15-year BBB GBP’ bonds* C40515Y INDEX
Positive working capital servicing rate Three-year average of ‘1-year BBB GBP’ bonds C4051Y INDEX
Negative working capital servicing rate Three-year average of Monthly average of UK resident monetary financial institutions’ (excl. Central Bank) sterling weighted average interest rate - time deposits with fixed original maturity <=1 year from private non-financial corporations (in percent) not seasonally adjusted CFMBI32

Sources: Bloomberg and Bank of England ‘*‘Note: Prior to 31 December 2014 the underlying rate is calculated using the Review Board’s methodology, adding 0.5pp to estimate a BBB- yield.

Trends in capital servicing rates

Government owned contractor rate

The Government owned contractor rate is a baseline profit rate that may be applied to qualifying contracts in place of the baseline profit rate set out on page 1.

The government owned contractor rate must only apply to qualifying defence contracts where:

  • the contract is between Secretary of State and a company incorporated under the Companies Act that is wholly owned by the UK Government; and
  • both parties to the contract agree that it should apply.

Calculation of Government owned contractor rate

The government owned contractor rate was set at a level that is opposite to the application of the SSRO funding adjustment. Prior to 2024/25 this approach delivers a contract profit rate of zero if steps 2, 5 and 6 are determined to be zero.

For 2024/25 onwards, Schedule 10 of the Procurement Act 2023 has come into force removing the SSRO funding adjustment from the previous six-step process. The approach remains the same for the four-step process brought into force by Schedule 10, such that it delivers a contract profit rate of zero if steps 2, 3 and 4 are determined to be zero.​

2020/21 2021/22 2022/23 2023/24 2024/25
Government owned contractor rate   0.057%* 0.046% 0.038% 0.00%

Note: The Government-owned contractor rate was first introduced for 2021/22.

‘*’ The SSRO did not recommend a government owned contractor rate for 2021/22 and the rate was assessed by the Secretary of State. The reason for doing so is set out in the London Gazette: https://www.thegazette.co.uk/notice/3760612

‘*’ A four-year average was used for 2022/23; a three-year average for pre-2022/23 and a three-year average (excluding the 2022/23 underlying rate) for 2023/24 and 2024/25.
The pre-2020/21 underlying rates used for the three-year average were: 2018/19: 7.94%, 2019/20: 8.50%
** Shown are the 2022/23 rates recommended by the SSRO. The Secretary of State determined the BPR for 2022/23 as an average of the composite underlying rates calculated by the SSRO for the three years prior to 2021 (8.50%, 8.23%, and 8.19%), keeping the BPR at 8.31 per cent.

  1. Note: The capital servicing adjustment accounts, at an aggregate level, for different levels of capital employed across the companies in the index and so sets a baseline upon which step 4 (previously step 6) of the contract profit rate applies.
