Lloyd's of London has advised staff at its Grade I-listed headquarters on Lime Street to work from home this week, as London braces for yet another spell of extreme heat, according to City AM. Temperatures in the Square Mile are forecast to reach 33C, with the UK Health Security Agency issuing amber heat-health alerts for London and the South East from Wednesday morning.
Around 1,200 people work out of the Lloyd's Building, the Richard Rogers-designed landmark that's housed the marketplace since 1986. Staff have reportedly been told to use their own judgement about coming in, though the building itself will stay open and air-conditioned for anyone who does, including the underwriters and brokers who trade there in person.
Lloyd's isn't alone. Several major City institutions relaxed desk policies during last month's heatwave, including JPMorgan, ING and Deutsche Bank, alongside insurer Hiscox, with JPMorgan easing its notoriously strict office attendance rules for the roughly 13,000 staff it employs in London. ING has reportedly held off doing the same this week, on the grounds that the Met Office hasn't issued the same red-level warning that triggered its June policy.
The timing is notable for Lloyd's specifically. Just two years ago, under previous chief executive John Neal, the market was pushing hard in the opposite direction, requiring staff back in the office three to four days a week and warning that Labour's proposed workplace reforms risked undermining business efficiency. Neal left the top job last year, and Lloyd's confirmed in May that an internal investigation had found he breached its compliance rules over an undisclosed relationship. Patrick Tiernan now leads the market.
The bigger story here isn't really about air conditioning. A recent ING research note warned that recurring European heatwaves are becoming a "new downside risk" for the wider economy, not just for the outdoor workers and farmers usually associated with heat risk. For an industry that spends its time pricing exactly this kind of climate exposure for clients, Lloyd's own operational response is a small but telling data point: even the organisations that write the policies on extreme weather are now routinely adjusting how they run their own offices around it.
2026 has already produced a near-unbroken run of heat alerts across England, with the UK Health Security Agency recording amber and yellow warnings through much of May, June and July. Whether this becomes the new summer normal for the Square Mile, rather than an occasional disruption, may be the more interesting question than whether the AC in EC3 can keep up.
