How to read these figures

Revenue and profit after tax are totals over the period. Net assets is what the company owns minus what it owes, as recorded on the balance sheet date. It is a book value, not a market valuation or a sale price, and ApplySafer does not publish one, because no reliable public source for the market value of a private UK company exists.

A change is measured against the period before. Where the two periods are of different lengths, part of any change in revenue and profit is the different length, and the page says so beside the figures.

Directors' pay is shown exactly as filed. Where a company publishes a total for all its directors but no separate figure for its highest paid director, the total is labelled as a total, is never presented as one person's pay, and is never divided by the number of directors.

The last three filed periods on the public record are shown.

Full accounts. A blank figure was not in the document.

Read from the documents this company filed at Companies House. Figures are as filed and are never adjusted, estimated or filled in.

Public records

Official record

Employment tribunal decisions: None found
“None found” is not a clean record. Settled and withdrawn claims are rarely published, and the gov.uk collection begins around 2017. Checked 27 Sep 2026.

What the tribunal count covers, and what it cannot

This counts decisions published on gov.uk that name this company as the respondent.
Claims that settled, were withdrawn or were never brought are often not published, and the collection begins around 2017.
An absence of decisions here is not evidence that no claim was ever made.
Northern Ireland has its own tribunal system and publishes separately, so decisions from Northern Ireland are not included in this count.
Decisions carry no company number; one is counted only where the respondent is named exactly as this company is registered (now or formerly), so a decision that spelled this employer's name differently would not be matched to it. ApplySafer does not record or show who brought any claim.
To read a decision, search the gov.uk employment tribunal decisions register.

How the director count is made

Counted from the Companies House register of officers: people currently appointed as a director with no resignation recorded. Company secretaries are not directors and are not counted, and officers who have resigned are not counted.

ApplySafer shows the number of directors and the directors' pay figures separately, exactly as each was filed. It never divides one by the other: in UK companies directors are often paid in dividends rather than salary, non-executive directors are frequently unpaid, and appointments can run for part of a year, so emoluments divided by directors is not anybody's salary.

From the Companies House register of officers, which is live rather than a periodic filing.

Registered charges are security given to lenders. Secured borrowing is normal business practice, and a charge count on its own says nothing about whether an employer is in difficulty.

The lender, amount and creation date of each charge come from the authenticated Companies House charges endpoint, which this deployment is not configured for. Only the counts held on the public register snapshot are shown.

How we source and check this record

Official filing: Filed with Companies House: identity, status, registered office, filing dates and any figures read from filed accounts.
Official record: Published by gov.uk: employment tribunal decisions, gender pay gap and supplier payment reports.
Employer statement: The employer's own words and job adverts, labelled as theirs and not checked by ApplySafer. An employer cannot change a filed fact.
Employee review: From people who worked here. Anonymous, read by a person before publishing. Each reviewer's stars are their own and never combined into a company score.

When something is missing: None found: we checked and found nothing, which is not a clean record.Not checked: ApplySafer does not search that source.Check could not be completed: our check did not finish; it is not a statement about the employer.Not yet available: the source does not hold it, or it has not been published.
Companies House: Matched by company number, never by name. Source last checked 1 Oct 2026. Companies House confirms who this company is; it does not verify, rate or combine the separate reviews, employer statements or public links in this record. This company's record on Companies House
gov.uk: Employment tribunal decisions, checked 27 Sep 2026; the Gender Pay Gap Service; the Payment Practices Service. A tribunal decision names a respondent, so it is matched by registered name and checked by a person where unclear.
Licence: Companies House and gov.uk data are published under the Open Government Licence. This record is a snapshot, not a live feed: each figure carries the date it belongs to, and accounts can reach the register nine months or more after the period they describe.
