Canary Wharf Group has sold one of its best office buildings for £625mn — to its own shareholders. On 13 August 2026 the estate’s owner confirmed the disposal of 1-5 Bank Street, the tower occupied by Société Générale and the European Bank for Reconstruction and Development, to affiliates of Brookfield and the Qatar Investment Authority, the two institutions that jointly own it. The transaction was structured at arm’s length, and more than £450mn of senior Debt was repaid out of the proceeds. It is the second large asset the estate has sold to a well-capitalised buyer this summer, and it says a good deal about how London office risk is being priced, financed and, crucially, who is willing to hold it.

Who bought what, and from whom

The seller is Canary Wharf Group, landlord of the Docklands estate. The buyers are separate vehicles controlled by Brookfield and the QIA — the pair that acquired Songbird Estates a decade ago and injected £400mn of fresh Equity in October 2023.

The asset is a 27-storey tower designed by Kohn Pedersen Fox and completed in 2019. Société Générale pre-let 280,000 sq ft across the lower floors, fitting out trading floors there. The EBRD took 365,000 sq ft across the top 13 floors, moving roughly 2,500 staff in during October 2022. The building is fully let to two institutional-grade tenants.

Why a sale to your own owners matters

On the face of it, moving an asset from one pocket to another achieves nothing. In practice it does three things. It crystallises a valuation for a Docklands tower at a moment when the market is thin. It converts an Illiquid asset into cash that retires debt at the operating company. And it shifts equity risk to shareholders with a longer Holding Period and lower cost of Capital than a leveraged property company. Canary Wharf Group had refinanced 1-5 Bank Street with a £564mn Loan extended to November 2029; repaying more than £450mn of senior debt shrinks the Balance Sheet where refinancing risk actually bites.

The debt story behind the deal

Credit has been the central question hanging over the estate since the pandemic. Fitch cut the group three notches in September 2024, taking the corporate rating from BB to B and senior secured debt from BB+ to BB-, citing refinancing risk on a £350mn bond maturing in April 2025. Gross debt was about £4.2bn in mid-2024.

The company has since pushed maturities out. A £610mn five-year loan from Apollo, completed in December 2024, was secured on most of the estate’s 1.2mn sq ft retail portfolio and used to repay bonds due in April 2025 and April 2026. It formed part of more than £2bn of refinancings, after which chief financial officer Becky Worthington indicated there were no material refinancings until 2028 and no significant office refinancing requirement until late 2029.

At 31 December 2025 the group reported a portfolio of £6.42bn, net debt of £3.58bn, a look-through loan-to-value ratio of 54.6 per cent, a weighted average cost of debt of 5.8 per cent and cash of £249.1mn.

An estate that no longer depends on banks

Office occupancy stood at 92.5 per cent across 6.9mn sq ft at the end of 2025, with 780,000 sq ft let during the year — the strongest leasing performance in more than a decade. Retail and leisure was 98.1 per cent occupied. Footfall reached 76 million visits, up 5.4 per cent.

Diversification is real rather than aspirational. More than 1,100 apartments are complete with over 270 under construction. One North Quay, an 823,000 sq ft laboratory building, is targeted for early 2028, and more than 40 life sciences organisations are already on the estate. QIA’s 8 Canada Square — HSBC’s former headquarters — faces a 1.1mn sq ft retrofit costed at £800mn to £1bn, converting upper floors to a hotel and viewing gallery.

Tenant churn runs both ways. Clifford Chance leaves by 2028, but HSBC has taken 210,000 sq ft at 40 Bank Street from 2027, Visa 300,000 sq ft at One Canada Square from 2028, and BBVA 250,000 sq ft.

Where the London office market actually is

Central London office investment reached roughly £4bn in the first half of 2026, still around 30 per cent below the long-run average. But £2.6bn was under offer at the end of June, above the long-term average, suggesting the pipeline is refilling.

Pricing has stabilised rather than recovered. Prime yields sat at about 3.75 per cent in the West End and 5.25 per cent in the City and Southbank in the second quarter, with prime West End Core rents at £185 per sq ft and City Core at £102.50. Canary Wharf prime rents were around £62.50 per sq ft, with rent-free periods of 27 to 30 months against roughly 24 in core markets. That discount is the market’s honest assessment of Docklands risk.

The year’s largest single transaction was also a Canary Wharf sale: Barclays bought its global headquarters at One Churchill Place from the group for £750mn in June 2026, taking a 999-year leasehold over the 1mn sq ft tower it has occupied since 2005. Other 2026 deals — 1 St James’s Square at £282mn, Stirling Square at £220mn, 123 Victoria Street at more than £210mn — are an order of magnitude smaller.

The risks that have not gone away

Two large sales in three months raise a fair question about whether Canary Wharf Group is selling its best Assets to support its balance sheet. The remaining portfolio is weighted toward space that needs capital, and the retrofit pipeline is expensive. Interest costs of 5.8 per cent still exceed several asset yields. And because the buyers were the existing shareholders, the price was not tested against a competitive field, limiting how far it reads as a market marker.

A borough sitting on the proceeds

An awkward story runs alongside. Tower Hamlets, the borough containing Canary Wharf, holds more than £260mn of unspent developer contributions — the largest balance of any English or Welsh council, according to a Home Builders Federation survey of 243 authorities published in March 2026. Nationally £9bn sits unspent: £6.6bn from section 106 agreements, £2.2bn from the community infrastructure levy. In 2023/24 Tower Hamlets received £15.9mn and spent £85,270.

What the deal really signals

The message is not that London offices are booming. It is that the best-let buildings, on long leases to strong covenants, still clear at large numbers when patient capital will hold them. For everything else, the gap between prime and the rest remains this market’s defining feature.
