Who Owns Heathrow Airport?

Heathrow is owned by foreign investors, nearly half of them sovereign wealth funds. After Spain’s Ferrovial sold most of its stake in December 2024, the largest shareholder is the French firm Ardian at about 22.6%, followed by the Qatar Investment Authority at 20% and Saudi Arabia’s Public Investment Fund at 15%. Companies House traces the chain to a company still named after the 2006 takeover vehicle. Ownership verified 6 September 2026.

Who owns Heathrow Airport today?

The airport is HEATHROW AIRPORT LIMITED (01991017), incorporated 19 February 1986 and registered at the Compass Centre, Hounslow.

The chain recorded at Companies House:

1. Heathrow Airport Limited (01991017) — the airport
2. Heathrow (AH) Limited (06458657) — 75%+ of shares and votes
3. Heathrow Airport Holdings Limited (05757208), controlled by ADI Finance 2 Limited at 75%+

Above those sits FGP TopCo, the company whose shareholders are the actual answer — and the UK register never reaches it.

Ultimate parent and corporate structure

Two names on that chain are fossils of a takeover.

Heathrow Airport Holdings Limited was previously named Airport Development and Investment Limited — the vehicle through which a Ferrovial-led consortium acquired BAA in 2006. ADI Finance 2 Limited carries its initials.

So the register preserves a twenty-year-old acquisition structure in the names of the companies that own Britain’s largest airport. This site has found the same pattern at Chelsea (Blueco), Asda (Bellis), Cadbury (Chromium), Boots (Blazing Star), Aston Villa (Recon Football) and Formula One (Alpha Prema). Acquisition vehicles outlive their acquisitions, and their names are the most reliable fingerprint of a leveraged buyout on the register.

The layering is not decorative. Heathrow is heavily debt-financed, and the separate holding companies exist to ring-fence borrowings at different levels — which is also why a passenger’s landing charge is set by a regulator with one eye on the airport’s debt.

Major shareholders or controlling persons

Reported holdings in FGP TopCo after the December 2024 transaction:

• Ardian (France) — about 22.6%
• Qatar Investment Authority — 20%
• Public Investment Fund (Saudi Arabia) — 15%
• Caisse de dépôt et placement du Québec — about 12.6%
• GIC (Singapore) — about 11.2%
• Australian Retirement Trust — about 11.2%
• Ferrovial (Spain) — about 5.25%

Two observations. No shareholder is British. And roughly 46% of Heathrow is held by sovereign wealth funds — Qatar, Saudi Arabia and Singapore — meaning close to half of Britain’s principal international airport is owned by foreign states.

No single holder controls it. Ardian’s 22.6% is the largest and falls below the 25% at which UK rules would record significant control — though the exemption is academic here, because the register stops several companies earlier.

Ferrovial’s near-exit ends an eighteen-year involvement. It ran the airport from 2006, sold Gatwick, Stansted and Edinburgh under competition orders, and retained just over 5%.

Official records and evidence

Every company number, incorporation date, PSC entry and the Airport Development and Investment previous name are Companies House records and can be checked directly.

The shareholdings are not. The register names UK holding companies and stops before FGP TopCo, so no British filing establishes who owns Heathrow. Those percentages come from the buyers’ and sellers’ own announcements — Ardian’s, PIF’s and Ferrovial’s — and from Heathrow’s investor reporting, which it publishes because of its listed debt rather than because any company law requires it.

That is the practical position: Heathrow discloses to its bondholders, and the public benefits from the disclosure indirectly. Regulation of its charges is a matter for the Civil Aviation Authority, not Companies House, which does not verify most filed information.

Ownership history and changes

Heathrow was state-owned for its first four decades, run by the British Airports Authority created in 1966.

• 1986 — BAA is privatised; Heathrow Airport Limited is incorporated on 19 February.
• 2006 — a consortium led by Spain’s Ferrovial acquires BAA through Airport Development and Investment Limited.
• 2009 onward — the Competition Commission requires BAA to sell Gatwick, Stansted and one Scottish airport, ending common ownership of London’s main airports.
• 2012 — the group is renamed Heathrow Airport Holdings.
• December 2024 — Ardian and Saudi Arabia’s PIF acquire a combined 37.6% for a reported £3.26bn; Ferrovial retains about 5%.

The forced break-up is the part with lasting consequences. Until 2009 one company owned Heathrow, Gatwick and Stansted; competition authorities ended that, which is why London’s airports now have entirely different owners.

Related companies and brands

The group owns Heathrow Express and the airport’s terminals, but not the airlines, the shops or most of the ground handling — those are separate businesses operating under contract or lease.

Gatwick is majority-owned by France’s VINCI Airports; Stansted and Manchester belong to Manchester Airports Group, in which Manchester councils hold a substantial stake; Luton is owned by its borough council. London’s airports span foreign infrastructure funds and English local authorities, with no common owner.

Ferrovial, Ardian and the sovereign funds hold infrastructure interests worldwide. Those share a shareholder with Heathrow, not an owner — the distinction this site draws throughout.
