You have found a promising council contract, the numbers look workable, and then you spot a line in the tender pack: “TUPE may apply.” For a lot of small bidders, that is the moment the bid suddenly feels heavier. TUPE — the Transfer of Undertakings (Protection of Employment) Regulations — has a fearsome reputation, but the principle behind it is straightforward and, once you understand it, very manageable.

This guide explains when TUPE bites on public-sector contracts and re-tenders, what duties it places on you as an incoming supplier, how to do proper due diligence, and — most importantly — how to cost the risk into your bid so it does not quietly eat your margin.

This article is general information, not legal or HR advice. TUPE is technical and outcomes turn on the specific facts, and the rules can change. Check the current position on GOV.UK and take professional legal or HR advice before relying on any TUPE position in a live bid.

What TUPE is, in plain terms

TUPE exists to protect employees when the business or service they work in changes hands. The core idea: if you take over an activity that was being done by someone else's staff, those staff may transfer to you automatically, keeping their existing terms, pay, length of service and continuity of employment. You inherit them as if you had always employed them. You cannot simply cherry-pick the people you want or quietly cut their terms because there is a new contractor.

In the public sector this comes up constantly, because services are routinely re-tendered. A cleaning contract, a grounds-maintenance service, an IT helpdesk, a care service — when these change provider, the people doing the work often come with the work.

When does TUPE apply on a public contract?

There are two situations to watch. The first is a straightforward business transfer. The second, and far more common in public procurement, is a service provision change: where a service moves from one provider to another (or back in-house, or out to a new contractor). If an identifiable group of staff is principally dedicated to delivering that service, TUPE will usually apply when the service moves to you.

So if you win a contract to clean a set of council buildings that the outgoing contractor's team currently cleans, the likelihood is that team transfers to you on their existing terms. Note the careful wording in tender packs: buyers often say TUPE “may” apply because the final position depends on facts only the outgoing provider can confirm. Treat “may” as “probably will” until you have evidence otherwise.

The mistake is reading “TUPE may apply” as a footnote. On a people-heavy service contract, it is often the single biggest factor in whether the bid is actually profitable.

Due diligence: the questions you must ask

You cannot price what you cannot see. As a bidder, you are entitled to ask for — and the buyer should provide — anonymised employee liability information about the staff who would transfer. The detail you want includes:

  • How many staff, and on what contracts (full-time, part-time, fixed-term, casual).
  • Pay rates, holiday entitlement, and any enhanced terms.
  • Pension arrangements — public-sector pensions can be a major cost.
  • Length of service (this drives redundancy and notice costs later).
  • Any outstanding grievances, disciplinary issues or tribunal claims.
  • Existing benefits, allowances and contractual perks.

If the buyer is vague, push politely but firmly, and document what you were and were not told. Strong, well-organised information requests are a hallmark of a serious bidder, and the way you handle them feeds straight into a clear-eyed bid or no-bid decision.

Your duties when staff transfer to you

If TUPE applies, you take on real legal responsibilities. You inherit the employees on their existing terms and continuous service. You generally cannot change those terms simply because of the transfer, even with agreement, unless there is a permitted economic, technical or organisational reason. And both the outgoing and incoming employers have duties to inform and consult recognised employee representatives about the transfer — what is happening, when, and any measures that will affect staff. Skipping consultation is one of the most common and costly TUPE failings, carrying compensation of up to several weeks' pay per affected employee.

Costing TUPE into your bid

This is where small bidders win or lose money. The transferring workforce is not a blank slate you can model at minimum wage — you inherit their actual costs. Build your pricing around the real numbers from due diligence: their pay, their holiday, their pension, their service-related liabilities. Then add a sensible contingency for the unknowns.

A practical example: you bid for a five-year grounds-maintenance contract assuming a lean new team on entry-level pay. In reality, eight staff transfer in, several with 15 years' service and an enhanced pension. Your labour cost is far higher than modelled, and if the contract goes wrong, your redundancy bill is substantial. The bid that looked profitable on a clean sheet is loss-making on the real numbers. Get the staffing assumptions right and the rest of your tender response rests on solid ground.

Common traps to avoid

A few errors come up again and again. Assuming TUPE does not apply because the service is changing shape — it often still does. Failing to consult, then facing protective-award claims. Promising savings to the buyer that depend on cutting transferred staff's terms, which TUPE blocks. And underestimating exit costs: if you ever lose the contract at re-tender, those staff may transfer out again, but if they do not, you could be left carrying redundancy liabilities. Understanding the redundancy process for small employers before you bid is far better than learning it under pressure.

Turning TUPE from a threat into an edge

Handled well, TUPE can actually work in your favour. An experienced, embedded workforce means continuity, local knowledge and a service that runs from day one — buyers value that, and you can say so in your bid. Treating transferring staff fairly and professionally also builds the kind of reputation that wins repeat public work.

Frequently asked questions

Can I avoid TUPE by hiring fewer staff or restructuring the service?

Not easily, and not by design. If your real intention is to take on the same activity with the same essential workforce, TUPE will usually apply regardless of how you label things. You can reorganise a service for genuine commercial reasons over time, but you cannot dodge TUPE simply to avoid inheriting staff. Trying to engineer around it tends to create tribunal risk rather than remove it.

What happens if the buyer will not give me TUPE information?

Press for anonymised employee liability information — it is reasonable and expected in a properly run procurement, and good buyers provide it. If the information stays vague, factor that uncertainty into your price with a larger contingency, raise it formally through the tender's clarification process, and weigh whether the unknowns make the contract too risky to pursue. Document everything you ask.

Do transferred staff keep their public-sector pension?

Pensions are one of the more complex parts of a public-sector TUPE transfer and are treated differently from other terms. There are specific protections, particularly under arrangements designed to give transferring staff broadly comparable pensions. Because the cost can be significant, this is exactly the kind of point to clarify in due diligence and to check with a pensions or HR specialist before you finalise your bid price.

TUPE rewards bidders who do their homework. Map the staffing, price the reality, consult properly, and a contract that scares off your competitors can become one you win on confidence. To see which opportunities are worth that effort, browse current public-sector tenders on Tendarix.
