Fractional Controller Services in the United Kingdom

We give you accrual-grade accounting and management reporting you can run the business on. Delivered to FRS 102 / UK GAAP for UK businesses, priced in GBP.

Why UK businesses choose Salt

A UK controller is the layer that makes the year end a formality. The bookkeeper records; the accountant files; in between, someone has to own the close calendar, the control accounts, the accruals and prepayments, and the management pack that leadership actually reads on the eighth working day.

The close has to serve three destinations from one ledger: the quarterly MTD VAT return, the Companies House accounts due nine months after the reference date, and the CT600 at twelve months. Where those three disagree, the cause is almost always an uncontrolled close rather than a bookkeeping error.

We run the close in Xero with documented reconciliations for every control account, and report through Fathom or Syft. Approval policies are configured in the tools you already pay for rather than added as a new layer of software.

Standards and authorities

The framework your United Kingdom accounts are held to.

We prepare to UK GAAP (FRS 102) or IFRS, as adopted. These are the bodies that set that framework and the authorities you file with — linked so you can verify the standard rather than take our word for it.

Listed for reference. Salt Accounting Group is not stating membership, registration or affiliation with any of these organisations. Where a filing must be lodged by a registered local agent, it is — your agent keeps the lodgement and the professional sign-off.
