Umbrella company compliance software for agencies

When an umbrella in your chain fails on payroll, the bill can land on you, whole. This guide covers what joint and several liability actually demands of an agency, what changes from April 2027, and what your records have to show on the day someone asks.

The liability is absolute

Joint and several liability for umbrella payroll failures means exactly what it says: HMRC does not have to chase the umbrella first, prove your fault, or apportion the bill. If a company in your chain fails on PAYE, the agency that supplied through it can be pursued for the lot FA 2026 s.24.

What that changes is the meaning of due diligence. A folder of accreditation certificates collected at onboarding is not a defence; what stands up is evidence of ongoing assessment: that you knew which umbrellas your workers were paid through, held current evidence on each, and reacted when a file went stale.

The test to hold yourself to: for any umbrella you pay through, can you produce today, in minutes, the evidence on file, its expiry position, and the list of live placements running through that company? If the honest answer is a day of spreadsheet archaeology, the liability is not being managed.

And the ground moves again in 2027

Umbrella regulation under the Employment Rights Act 2025 is expected from April 2027, with agencies answering for the umbrella companies they pay through. The direction of travel is one-way: the umbrella chain stops being someone else’s problem. An agency whose records already treat each umbrella as a first-class file, evidence, expiries, linked placements, meets that date as an administrative change.

What the software has to do

The solution

BookKept treats the umbrella chain as a first-class record

Every umbrella placement must name its umbrella company; each company carries its own evidence file with expiry chasing; the compliance dashboard shows the evidence position per umbrella with live placement counts and red flags; and every evidence act lands on a hash-chained audit trail. The join an inspector asks for is the product’s spine, not an export.
