London Prepares for Sustainability Events and Major Rail Disruption in November

London is set for the second half of November 2026, with a packed schedule of conferences, trade shows and other industry events. ExCeL London is preparing to welcome a string of large-scale meetings celebrating energy efficiency, building performance and environmental sustainability. Heathrow Airport has set out its plans for incentivising airlines to adopt the use of sustainable aviation fuel (SAF) in 2027. Transport logistics will also be part of the discussion later in the month. On 28 and 29 November, a significant engineering initiative at Dolphin Junction will close off railway lines near London Paddington, impacting the Elizabeth line, Heathrow Express and the Great Western Railway routes to and from the capital and Heathrow Airport, in addition to the Thames Valley. Such planned activities show a more realistic read on London’s corporate travel activity than unconfirmed claims of new airport fuel-checks, automated event-venue audit programmes or new express rail routes.

Heathrow publishes its 2027 sustainable aviation fuel guidance

Heathrow Airport published its Sustainable Aviation Fuel Incentive at Heathrow 2027 guidance on 30 October 2026. The document outlines how airlines can participate in the airport’s financial incentive scheme by arranging deliveries of qualifying SAF to Heathrow during 2027.

The scheme is designed to reduce the additional cost of sustainable aviation fuel compared with conventional fossil-based jet fuel. Heathrow plans to distribute financial credits to participating airlines that meet the scheme’s requirements and provide the necessary delivery and sustainability documentation.

The 2027 incentive pot is valued at approximately £81.24 million. Heathrow’s guidance sets out a proposed incentive of £700 per tonne of SAF delivered, subject to the scheme’s conditions and allocation limits.

Airlines intending to participate must notify Heathrow by 5 pm UK time on 27 November 2026, stating their proposed SAF delivery volumes and nominated contact details. Heathrow plans to review submissions and communicate final allocations by 5pm on 4 December 2026.

The airport’s scheme should not be confused with the UK’s statutory SAF Mandate. The national mandate, administered through the Department for Transport’s regulatory framework, requires an increasing share of sustainable aviation fuel in the UK’s overall aviation fuel supply. Its obligation year runs from 1 January to 31 December.

Heathrow’s incentive is a separate commercial programme intended to encourage additional SAF use at the airport. The airport requires evidence of fuel sustainability, delivery and eligibility before issuing credits. It does not replace the national regulatory system or act as the authority responsible for statutory compliance.

ExCeL London prepares for two sustainability-focused exhibitions

ExCeL London will host two significant events on 25 and 26 November 2026: emex – The Energy Management and Smart Buildings Expo – and elementalLONDON.

The emex exhibition brings together energy managers, building professionals, technology suppliers and organisations looking to improve energy efficiency. Its programme includes conference sessions, specialist exhibitors and practical discussions about reducing energy consumption and improving building performance.

The event is expected to feature more than 100 speakers and over 100 specialist exhibitors. Its agenda covers energy management, connected buildings and technologies that can help organisations manage their environmental impact.

ElementalLONDON will focus on improving the efficiency of commercial, industrial and large residential buildings. The event is co-located with London Build and incorporates CIBSE Build2Perform, creating a platform for professionals working in construction, building services, retrofit and sustainable building design.

Its published programme includes 15 conference stages and more than 650 exhibitors. Topics include building performance, climate solutions, social housing and energy efficiency.

Both events will take place at ExCeL London, with Custom House station providing access through the Elizabeth line and Docklands Light Railway.

The exhibitions also reflect ExCeL’s existing environmental commitments. The venue’s Net Zero Transition Plan, published in 2025, sets a target of achieving net zero by 2045. ExCeL also reports that it has maintained a zero-waste-to-landfill policy for more than a decade and holds carbon-neutral certification under PAS 2060.

These are established sustainability measures rather than evidence of a newly deployed automated auditing dashboard. No official announcement confirms that ExCeL introduced a mandatory digital system for organisers to calculate supply-chain waste on 10 November.

Elizabeth line and Heathrow Express face a November shutdown

The most significant transport development for travellers later this month is the planned engineering closure at Dolphin Junction.

Network Rail has scheduled the initial phase of a £27.8 million upgrade for Saturday 28 and Sunday 29 November. The work involves replacing part of the junction’s track layout near Slough to support future railway operations and improve reliability.

The closure will prevent trains from running between Heathrow Airport, Maidenhead and London Paddington during the weekend. Heathrow Express services will also be affected, meaning passengers will not have their usual direct rail connection between Heathrow and Paddington.

Elizabeth line services will experience wider disruption. No services will operate between Heathrow Airport and Shenfield or between Maidenhead and Abbey Wood during the closure. A limited service of two trains per hour will continue between Reading and Maidenhead.

Replacement buses are planned on sections of the affected network, including services between Maidenhead and Slough, and between Slough and Ealing Broadway. Additional replacement services will operate between Stratford and Romford, and between Romford and Shenfield.

Passengers travelling to central London from Heathrow should allow extra time and check their journey before departure. Those connecting to flights, business meetings or onward rail services may need to consider alternative routes using London Underground or other available transport connections.

The disruption is part of a wider programme of railway upgrades across the Thames Valley. Network Rail has also announced further engineering work over the Christmas and New Year period, meaning passengers should monitor official travel updates beyond the November weekend.

London balances business events with transport planning

Certainly like with the portfolio of events and train networks, a strong set back of the business tourism in November is still going to be seen in London. By giving the airline industry a first impression of the incentive guide for SAF in 2027, Heathrow allows them to prepare to provide sustainable fuels, and by having the ExCeL London in November to establish connections with energy, construction, and environmental industry representatives, and the Dolphin Junction diversion is a signal for those travelling by air or coming to the city for an event. Certainly not any major changes will cause any trouble to the delegates and visitors, but the rescheduling of rescheduling from two transport schedules and almost the whole exposition schedule happening in the fourth week of the month, not the last one, and for the latter one with a wide variety of potential departure time changes and accommodation-location changes, check them all out in advance.
