In the UK television series Dragon's Den, what is the main purpose of due diligence after a televised deal?

In the UK television series Dragon's Den, due diligence after a televised deal is mainly used to verify the business information.

Due diligence is the checking process that follows an investor's on-screen offer. It can involve reviewing accounts, contracts, ownership records, intellectual-property claims, liabilities and other evidence supplied by the entrepreneur. The purpose is to establish whether the business matches the presentation and whether the proposed investment is commercially acceptable.

A deal shown on television is therefore not automatically a completed transaction. The parties may revise the terms, discover problems or decide not to proceed after the checks. This is a normal feature of real investment rather than a special rule invented for the programme.

Due diligence is different from filming and editing. It concerns the underlying business and its records, not the production schedule or the final television presentation.
