London Build Scales up to Excel for UK Construction

London Build Scales up to Excel for UK Construction

London Build’s decision to leave Olympia for Excel London after a decade in West Kensington is more than a change of postcode. It is a statement about where the centre of gravity in the UK’s built environment calendar now sits, and about the ambitions of the company that owns the show.

The 2026 edition, running across two days on 25 and 26 November, will occupy twelve halls at Excel and arrive co-located with elementalLONDON, the sustainability and building services event that organiser Nineteen Group launched only last year. For contractors, suppliers, developers and public sector buyers who plan their autumn around the fixture, the move reshapes the largest gathering in domestic construction and consolidates it alongside the other major shows migrating east to the Royal Docks.

The commercial logic matters to anyone who exhibits, sponsors or sends teams to these events. London Build has run at Olympia since 2015 and grown into the UK’s biggest construction expo, drawing more than 25,000 attendees and over 650 exhibitors. Outgrowing a venue is a good problem to have, but it forces a choice between capping the show and finding room to scale.

Nineteen Group has chosen scale, and in doing so has placed two of its events, London Build and elementalLONDON, inside the same expanding venue that already hosts a widening slice of the country’s exhibition business. The relocation therefore reads as both a growth play for the show itself and a bet on Excel as the default home for large industrial and trade gatherings.

Briefing

• London Build relocates from Olympia to Excel London for its 2026 edition on 25 and 26 November, taking twelve halls and co-locating with elementalLONDON for the first time.
• The show is the third Nineteen Group event to switch to Excel inside twelve months, following the Retail Technology Show and elementalLONDON.
• Organisers expect more than 25,000 attendees, 650-plus exhibitors, 900-plus speakers and over 40 networking events across the two days.
• The conference programme spans 17 CPD-accredited stages covering net zero, AI and digital construction, fire safety, modern methods of construction, housing and infrastructure, and skills.
• Excel is running a further £100 million investment programme after a £350 million spend over five years, and says London Build is one of 23 shows relocating or launching at the venue in 2026.

Why the Venue Move Carries Commercial Weight

The relocation is best understood as part of a deliberate portfolio strategy rather than a one-off logistics decision. London Build becomes the third event Nineteen Group has moved to Excel within a year, after the Retail Technology Show made the switch in April 2025 and posted 11 per cent year-on-year growth to reach 14,000 visitors and 438 exhibitors.

That precedent gave the organiser a template and a reason to repeat it with its construction flagship. Group Managing Director Mike Costain framed the move around capacity, describing the venue’s support as what “allows us to realise our wider expansion goals.” The message to exhibitors is that the show intends to keep growing rather than settle at its current size, which has direct implications for stand availability, sponsorship tiers and the calibre of buyers the event can attract.

For Excel, London Build is a marquee addition to an event roster that is filling quickly. Nick Coffey, the venue’s Head of Exhibition Business Development, noted that London Build is one of “23 shows that are either relocating or launching at Excel in 2026,” a figure that speaks to a broader repositioning of the UK exhibition market around the Royal Docks site.

Excel has spent £350 million over five years, including a capacity expansion that opened in 2025, and has a further £100 million programme underway targeting digital infrastructure, wayfinding, food and beverage and general visitor experience. Those numbers matter because exhibition economics depend on footfall quality, connectivity and the ability to handle large builds and heavy plant. A venue investing at that level is signalling that it wants the large, logistically demanding trade shows that construction events represent.

Two Shows Under One Roof

The co-location with elementalLONDON is the structural change most likely to alter how the built environment supply chain uses the event. elementalLONDON, launched in 2025, is Nineteen Group’s dedicated platform for connecting specifiers and suppliers around energy, performance and sustainability in buildings. Pairing it with London Build creates a single destination that runs from heavy construction and civils through to building services, facades, insulation and the specification decisions that determine a building’s operational carbon.

For manufacturers and technology providers, that combination widens the audience reachable from a single stand build and shortens the distance between a product pitch and the specifier who signs it off.

The pairing also reflects where regulatory and commercial pressure is pushing the industry. Sustainability, net zero and building performance are no longer confined to a niche audience of consultants; they now drive procurement, insurance, valuation and compliance across housing, commercial and infrastructure work.

Bringing the specification community into the same halls as contractors and developers acknowledges that these decisions are increasingly made together rather than in sequence.

Whether the two events retain distinct identities or gradually blur into one built environment show will be worth watching, but for 2026 the practical effect is a larger, more integrated marketplace at a single point in the calendar.

A Conference Programme Built Around Industry Pressure Points

Content is doing heavy lifting at London Build, and the scale of the conference offer is one of the show’s clearest differentiators. The 2026 programme spans 17 CPD-accredited stages with more than 900 speakers, and the agenda tracks the issues currently consuming boardroom and site attention alike.

Sustainability and net zero, AI and digital construction, fire safety, modern methods of construction, housing and infrastructure, skills and workforce development, and architecture and design innovation all feature, alongside dedicated diversity and inclusion programming. For time-pressed professionals, the CPD accreditation turns two days of attendance into a measurable training return rather than a soft networking exercise.

The speaker roster leans toward practitioners with delivery responsibility rather than platform commentators, which tends to raise the quality of the sessions. Among the first tranche announced are Luke Hands, Director of Health, Safety, Environment and Quality at Ardmore Group, Ilka van Heerden, Head of Preconstruction at Structure Tone UK, Andrew J Taylor, Group Planning and Sustainability Director at Vistry Group, and Diana Otieno, Head of Resident Engagement and Compliance for Fire Safety at Peabody.

They sit alongside senior figures from Wates, Keepmoat Homes, Landsec, BAM, Sisk, RIBA and others. The presence of fire safety and compliance leaders is telling, given the continuing weight of the Building Safety Act on developers and building owners, and it points to a programme shaped by live commercial and legal exposure rather than general interest.

The Buyer and Supplier Ecosystem

The value of a trade show ultimately rests on who walks the floor, and London Build’s draw is the seniority and breadth of its attendee base. Organisers expect more than 25,000 visitors spanning contractors and subcontractors, developers and housebuilders, architects and engineers, sustainability and technology teams, consultancies, local authorities and housing associations.

The job titles skew toward decision-makers, including chief executives, managing directors, construction and design managers, digital construction managers and directors of sustainability. Companies expected across the two days include Balfour Beatty, Mace, AECOM, Morgan Sindall, Skanska, Willmott Dixon, Laing O’Rourke, Costain, Arup, Lendlease and Transport for London, a roster that reflects the show’s reach into both private delivery and public infrastructure.

On the supply side, the confirmed exhibitor list points to the show’s building services and specification centre of gravity. Names such as Siemens, Bosch, Rockwool, Polypipe, Howdens, James Hardie, Quelfire and Baldwin Boxall cover fire protection, insulation, drainage, joinery, controls and fabric, the product categories where the co-location with elementalLONDON is most relevant.

For smaller innovators, the event offers a start-up zone and showcases designed to put emerging technology in front of buyers who would otherwise be hard to reach. That mix of established manufacturers and early-stage entrants is part of what sustains footfall, since visitors come both to reorder from known suppliers and to scout the products that will shape the next procurement cycle.

What the Consolidation Means for the Wider Calendar

The most durable consequence of the move may be the way it concentrates the UK’s major construction events at a single venue. Excel already hosts UK Construction Week London in May, co-located with Futurebuild and the Stone and Surfaces Show, and now adds London Build and elementalLONDON in November.

Two of the country’s largest built environment gatherings are therefore anchored to the same Royal Docks campus, served by the Elizabeth line and the DLR, within the same calendar year. That geographic concentration simplifies planning for exhibitors who work both shows and strengthens Excel’s negotiating position, while raising a longer-term question about how much differentiation the market can sustain between events sharing a venue and, increasingly, an audience.

For the industry that attends, the practical takeaways are straightforward. Exhibitors weighing stand investment for late 2026 are now buying into a larger footprint with a broader, sustainability-inflected audience, and should plan their propositions accordingly. Visitors gain a denser two days, with more content, more suppliers and the specification community folded into the same halls, but will need to be deliberate about navigating a bigger floor plan.

Registration for free two-day tickets is open, and given the scale of the relocated event, early planning will matter more than it did at Olympia. The move confirms that London Build has outgrown its origins, and that the UK’s construction show season is consolidating around fewer, larger, more commercially ambitious fixtures.
