Scope
Description
The National Audit Office (NAO) is the UK's independent public spending watchdog. The NAO supports Parliament in holding government to account and helps improve public services through its high-quality audits.
We are seeking bids from interested suppliers experienced in providing comprehensive Occupational Health (OH) service comprised of Health Assessment Questionnaires, Management Referrals, DSE Assessments, Immunisation Programmes, Employee Assistance Programme and Health Screening services.
The NAO's strategic ambitions for the next 5 years are more productive and resilient public services, and better financial management and reporting in government. People and Culture is a key capability to deliver this. Our definition of good core People and Culture capability includes consistently high-performing people and teams, motivated by and focused on the NAO's purpose and strategy and that our people have high levels of engagement, and we experience low levels of sickness absence.
This contract has strategic importance and will be a key enabler of NAO performance and productivity.
The contract will be divided into 3 lots as follows:
• Lot 1 Occupational Health services
• Lot 2 Employment Assistance programme
• Lot 3 Health Screening
Interested suppliers will be able to submit a bid for a maximum of the 3 lots in across the services, which means if a single supplier bids for the maximum 3 lots and meets our required criteria and otherwise qualify for the award of a contract, they will be awarded all 3 lots.
The new contract(s) will run for an initial period of 3 years from Friday 2nd January 2026 until Monday 1st January 2029 with the option to further extend for a period of up to 2 years (by 2 periods of 12 months) until Wednesday 1st January 2031.

• Lot 1 Occupational Health services - £615k
• Lot 2 Employment Assistance programme - £110k
• Lot 3 Health Screening - £600k
