BANHAM PATENT LOCKS LIMITED
BANHAM PATENT LOCKS LIMITED is a private company limited by shares registered in England and Wales under company number 00457812. It was incorporated on 12 August 1948 as Banhams Patent Locks Limited and has carried its current name since 21 October 2019, the date of the certificate of incorporation on change of name issued by Companies House. The register records the company as active, with its registered office at 20 Thornsett Road, Earlsfield, London SW18 4EF.
The company trades as Banham, a London security business. Its filed accounts describe it as a burglary-prevention specialist and attribute all of its turnover to goods and services relating to burglary prevention. The banham.co.uk website, whose footer states that it is operated by the company registered under number 00457812, offers locks, keys with key cutting and key registration, security and fire doors, burglar alarms with alarm monitoring, keyholding and alarm response, CCTV and entry and access-control systems, safes, gates and shutters, and an emergency locksmith service, sold through London showrooms; the Thornsett Road site is its head office and south London showroom. The brand dates its history to 1926, before the present company was formed. The register’s SIC code, 74909 (other professional, scientific and technical activities not elsewhere classified), does not describe this business.
BANHAM PATENT LOCKS LIMITED files full audited accounts under FRS 102. For the year ended 31 December 2025 (approved 18 September 2026, filed 25 September 2026) it reported company-level turnover of £45,201,564 (2024, restated: £43,796,816) and gross profit of £23,814,055. Operating profit was £202,722; profit before tax of £814,864 included £612,142 of interest income, £230,702 of it from group companies, so most of the pre-tax profit came from interest rather than trading. Profit for the year was £635,321 (2024: £865,712, helped by a tax credit). Net assets fell from £27,757,060 to £26,933,531 because interim dividends of £1,458,850 exceeded the year’s profit, not because of a trading loss. The company reported no bank borrowings, £9.5m of current-asset investments and £2.9m of cash. It employed an average of 446 people including directors (2024: 437). The 2024 comparatives were restated for a change in how software-as-a-service implementation costs are accounted for.
Other dated events on the register: a charge registered on 20 December 2013 was recorded as satisfied in full on 8 August 2023. The filing history, reviewed across all six pages, contains no insolvency, administration or strike-off filings.

Shareholders

Shareholders of BANHAM PATENT LOCKS LIMITED
BANHAM PATENT LOCKS LIMITED has one disclosed shareholder. Its last full shareholder list at Companies House, in the annual return made up to 30 October 2015, records Banhams Patent Locks Holdings Limited (renamed Banham Patent Locks Holdings Limited on 13 December 2019, company number 08207714) as holder of all 114,688 ordinary shares of £0.05 each, a 100% direct holding. The confirmation statement of 30 October 2016 restates the capital as 114,688 ordinary shares (aggregate nominal value £5,734.40), and every confirmation statement from 2017 to 30 October 2025 was filed with no updates.
The PSC register names the parent as the only active person with significant control, under ownership of shares of 75% or more, voting rights of 75% or more and the right to appoint or remove directors, notified with effect from 30 October 2022. Note 28 of the 2025 accounts names the same company as immediate and ultimate parent.
Two discrepancies in the company’s own filings, both published here as filed. First, note 23 of the 2025 accounts gives the issued capital as 114,680 ordinary shares of £0.05 (£5,734), eight shares fewer than the register filings. Second, from 30 October 2016 until 2 May 2023 the PSC register named five individuals, each only under the significant influence or control limb and none as a shareholder. The parent was not entered until the PSC02 filed on 24 February 2023, even though the 2015 return already showed it as sole shareholder.
Ultimate beneficial ownership
The parent’s PSC register (08207714) names two active persons with significant control, Charles Richard Hallatt and Lucie Anh Francis Banham, both notified on 2 May 2023 and both registered only as having significant influence or control. Neither is registered under an ownership-of-shares or voting-rights limb, so no ownership stake attaches to either of them. No natural person is registered at either level as holding more than 25% of shares or voting rights. The parent’s own shareholder list was not reviewed for this page, and no effective ownership percentage is calculated.
Data availability
Partial. UK private companies file shareholder lists only with confirmation statements that report changes, so the latest full list for this company dates from 30 October 2015. The PSC register publishes bands, not precise percentages. The stored provider row (Banhams Patent Locks Holdings Ltd, 114,688 ordinary shares, 100%) matches the 2015 return, but it carries the parent’s pre-2019 name.

Directors and officers of BANHAM PATENT LOCKS LIMITED
The Companies House officer register for BANHAM PATENT LOCKS LIMITED, retrieved on 15 October 2026, lists 24 appointments. Twelve are current: eleven directors and one company secretary. The other twelve have ended. One person accounts for three appointments: a director since 1 July 1997, he was company secretary until 2 May 2023 and was re-appointed secretary on 12 December 2023.
Five of the current directors are recorded only as “appointed before 30 October 1991”, the register’s marker for appointments that pre-date its electronic records; no exact date is published for them. The other current directors were appointed on 1 July 1997, 3 August 2009, 1 April 2016, 8 May 2019 and 1 September 2020 (two appointments). The register records British nationality for ten of the eleven current directors and Irish for one, and gives England or the United Kingdom as country of residence. The directors listed in the 2025 accounts match the register.
Recent officer changes
- 9 March 2026: Claire Banham ceased to be a director (TM01 filed 25 March 2026). The register had recorded her appointment as before 30 October 1991.
- 27 March 2025: Craig Steven Phillips ceased to be a director, having been appointed on 2 May 2023.
- 12 December 2023: Thomas Joseph Ward was appointed company secretary. On the same day Claudette Anne Robinson, appointed on 2 May 2023, ceased to be a director.
Data availability
Full. Companies House publishes current and former directors and secretaries with appointment and resignation dates, nationality, country of residence, a service address and month and year of birth. Appointments made before about 1991 carry no exact date. The stored provider feed claims 34 results but stores only five rows. All five give 30 October 1991 as an exact appointment date where the register says only “appointed before” that date, and none of them is the company secretary.
