The information sought is not readily available in the format requested. Its compilation would involve a disproportionate amount of time and work as it would require a cross-check of all of the payments made by the Department during 2018, 2019 and 2020 against all contracts awarded following a public procurement process and a breakdown of each payment by goods, services or capital works.
My Department does however compile a register of contracts in excess of €25,000 (excluding VAT), for each year. Details for 2018 and 2019 can be found on my Department's website at the link https://www.gov.ie/en/collection/14085-public-contracts-awarded-over-25000-euro/.
The return for 2020 is currently being finalised and will be available at the link above following review by the Comptroller and Auditor General.
