Subcontract PAT Testing: A Tender Preparation Checklist

Colleagues discussing the tender plan and looking at a screen.

Before including a PAT testing subcontractor in a tender, establish what the client requires and what the delivery partner has actually agreed to provide. A clear brief is more useful than a long list of unsupported promises.

Use this checklist to prepare an enquiry for AiO’s subcontract PAT testing service. It supports a discussion; it does not confirm capacity, accreditation or acceptance of your client’s terms.

Send the specification and site list first

Provide the tender deadline, proposed start date and expected contract period.
List site addresses, approximate equipment counts and existing asset records.
Identify any 110V equipment, industrial connectors or specialist inspection requirements.
State required working hours, shutdown restrictions, inductions and access conditions.
Attach the client’s reporting specification and any requested sample format.

Request the evidence the contract needs

Topic	What to agree or request
Insurance	Required types and limits, current evidence and any client-specific conditions.
Competence	Relevant training, practical experience and the proposed inspection/testing scope.
Equipment	Suitability for the work and the arrangements for maintaining measurement confidence.
Safe working	Site-specific risks, method statements, access and disconnection authority.
Safeguarding and security	The exact checks, escorts or vetting the client requires, confirmed before allocation.
Reporting	Item identification, location, results, fault notes and the agreed delivery format.
Availability	Realistic dates, coverage and how changes or additional work will be handled.

Use current documents supplied for the enquiry. Do not copy qualification numbers, insurance limits or scheme membership claims from a generic template. Ask us to confirm any mandatory requirement before naming AiO in a submission.

Agree commercial boundaries

Define what counts as an item and separate optional work such as microwave leakage tests. Discuss travel, parking, out-of-hours access, extra equipment and repeat visits. Confirm who can authorise a change and how it will be priced.

For an uncertain inventory, show the counting assumptions in the bid and agree how the final scope will be reconciled. The appliance-counting guide is a useful starting point.

Plan the handover after award

Confirm the order, scope, contacts and reporting recipients.
Agree site readiness and approved access dates.
Confirm how failed, unavailable and unlocated items will be recorded and escalated.
Agree who authorises repairs and any return inspection or testing.
Check the first completed site’s reporting against the client’s requirements before progressing through the estate.
