ABACUS PROJECTS LIMITED
ABACUS PROJECTS LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 01460919, and its current status with Companies House is active. The company was incorporated on 13 November 1979 and lists its registered address as Kings Langley, United Kingdom. 1 shareholder is on record for ABACUS PROJECTS LIMITED, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Companies House and was last updated on 5 November 2026.

Officers
5
Three of the 5 officer records shown for ABACUS PROJECTS LIMITED are current appointments, filed with Companies House. Cullum McAlpine (appointed 2016-09-22) and Robert Wotherspoon (appointed 2018-10-31) both serve as Director; John Dempsey (appointed 2021-12-09) serves as Company Secretary. The remaining 2 records shown (Miles Shelley and Kevin Pearson) are former appointments that have since been resigned.
The register reports 15 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at ABACUS PROJECTS LIMITED sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
ABACUS PROJECTS LIMITED sits 3 levels below its ultimate parent, RENEWABLE ENERGY SYSTEMS HOLDINGS LIMITED, registered in United Kingdom. 1 subsidiary is recorded beneath it, across 1 jurisdiction. The full chain up to RENEWABLE ENERGY SYSTEMS HOLDINGS LIMITED is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by ABACUS PROJECTS LIMITED's own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 1 subsidiary spans United Kingdom jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
