London Build 2026 Takes on Britain’s Construction Delivery Challenges
Britain’s construction industry heads towards 2027 with £718 billion of planned infrastructure investment, a new government workforce strategy and building safety requirements that are still being absorbed across the sector. Turning those ambitions into completed projects will require contractors, consultants and suppliers to address some familiar problems, from workforce shortages and regulatory approvals to the practical limitations of digital construction.
These challenges will feature prominently at London Build 2026, taking place at Excel London on 25 and 26 November. Co-located with elementalLONDON, the exhibition brings together construction, infrastructure, architecture and building services professionals for two days of technical discussions, product demonstrations and industry networking.
With more than 450 exhibitors and an extensive conference programme, the event provides an opportunity to examine how the industry is approaching these challenges across different disciplines. The discussions are particularly timely following several important government and regulatory developments during October.

Turning Infrastructure Investment Into Construction
The National Infrastructure and Service Transformation Authority’s updated infrastructure pipeline, published in March 2026, identifies 734 planned projects covering £718 billion of public and private investment over the next decade.
The pipeline includes projects at different stages of development, with investment still dependent on individual funding, planning and procurement decisions. Its accompanying workforce analysis estimates that delivering the programme will require an average annual construction and infrastructure workforce of between 629,000 and 706,000 over the next five years.
The figures, published by the UK Government, provide a measure of the resources associated with the planned programme, although they should not be interpreted as an estimate of additional workers required across the entire construction industry.
Major infrastructure projects must accommodate increasingly demanding technical and environmental requirements while coordinating specialist contractors, materials suppliers and engineering teams. On transport schemes, these challenges are often compounded by restricted access, possessions, operational interfaces and the need to maintain existing services during construction.
London Build’s Civils & Infrastructure Stage will explore several of these subjects through discussions involving contractors and organisations working across the transport sector.
The scheduled panel UK Transport Projects That Are Leading Change brings together Richard Prime, Managing Director of Transport at BAM UK & Ireland; James Keegan, Director of Environment, Sustainability & Innovation at STRABAG; Simon Roberts, National Infrastructure Manager at BEWI; and Zakari Braou, Head of Information Management at SCS Railways.
Their respective backgrounds span infrastructure delivery, environmental management, materials and project information, offering different perspectives on the practical demands of major schemes.
The conference also includes a session examining collaboration between government and industry on the future of UK infrastructure. Alongside the formal presentations, the exhibition provides access to specialist suppliers and technical organisations whose products and services must operate within increasingly complex project requirements.
Building Safety and the Regulatory Process
Building safety regulation remains a significant consideration for residential developers, designers and contractors, particularly those working on higher-risk buildings.
The Building Safety Regulator’s latest published statistics, covering the rolling 12-week period to 5 October 2026, show an overall approval rate of 87% across 378 building control decisions involving higher-risk building categories. Of those decisions, 330 applications were approved.
The figures include 11,822 residential units associated with approved new-build and conversion applications and a further 8,649 units associated with external remediation approvals. The regulator reported a 97% approval rate for new-build applications, with a median approval time of 23 weeks. External remediation applications recorded an 87% approval rate and a median approval time of 32 weeks.
These figures indicate improvement in the processing of applications, although the time required for regulatory approval remains an important consideration in project planning. The regulator has also reported an increase in higher-risk building applications ahead of the introduction of the building safety levy on 1 October, with September submissions rising to 64 compared with 34 in August.
The regulator’s October data also places continuing emphasis on application quality, particularly where inadequate documentation or unresolved compliance issues prevent approval.
London Build’s Fire Safety Arena will examine these requirements through sessions covering regulatory compliance, design coordination, fire protection and the responsibilities associated with higher-risk buildings.
Among the scheduled discussions is Driving Compliance Across Design and Delivery: Gateways 2 & 3, bringing together representatives from OBEX, Scott Brownrigg, Hawkins\Brown and Ridge and Partners.
A separate session will examine evidence for fire-rated construction junctions, including the performance of interfaces between tested systems. Such details can be difficult to assess where products from different manufacturers meet, particularly around service penetrations, compartment boundaries and structural connections.
Regulatory compliance increasingly depends on the quality of information maintained throughout design and construction. Specifications, test evidence, installation records and subsequent design changes must remain consistent, with discrepancies potentially creating problems during approval, inspection or future building management.
Digital Construction Beyond the Demonstration
Digital information management presents similar challenges across wider construction projects, particularly where different organisations contribute to design, procurement, installation and asset records.
Building information models, site reporting platforms and project management systems frequently contain overlapping information maintained by separate teams. Drawings may be revised without corresponding updates to schedules, while product substitutions and site modifications can complicate the relationship between the approved design and the completed asset.
Artificial intelligence is beginning to assist with information retrieval, document analysis, design coordination and other technical tasks, but software outputs still depend on reliable source information and appropriate professional checks. Errors in specifications, outdated drawings or incomplete project records cannot be resolved through automated processing alone.
These operational questions feature in London Build’s AI & Digital Construction Arena and Innovation Hub.
The scheduled discussion Top Tech Trends Shaping UK Construction in 2027 includes Janne Aas-Jakobsen, Head of AI for Engineering at AECOM; Alex Richards, UK&I IT & Digital Director at BAM UK & Ireland; and Nidaa Alazmeh, Digital Project Delivery Lead at John Sisk & Son, with Rory Brown, Head of Innovation at Wates Group, chairing the session.
Other programme discussions address information sharing across the construction lifecycle and the barriers organisations encounter when introducing AI into established working practices.
Exhibitors including Autodesk, Matterport, PlanRadar and One Click LCA will present technologies associated with design information, spatial capture, project management and environmental assessment. Visitors will be able to examine the capabilities of different systems and discuss how they might integrate with existing project workflows.
The Women in BIM Tech Clinic, delivered in partnership with Graitec, adds a practical element through bookable one-to-one appointments covering AI, digital workflows, trusted data and information management.
For organisations already using digital construction platforms, these conversations may be more useful than general demonstrations of new software capabilities. Integration requirements, data ownership, interoperability and the quality of information transferred between project participants remain substantial considerations during implementation.
Housing, Retrofit and Building Performance
Housing delivery occupies a considerable part of the conference programme, alongside discussions examining modern methods of construction, digital collaboration and the performance of completed buildings.
The UK Housing Stage will consider design, delivery and development issues, while a scheduled digital collaboration discussion brings together representatives from housing associations including A2Dominion, Riverside Group, L&Q Group and Metropolitan Thames Valley.
Housing providers must maintain reliable information across extensive property portfolios, often incorporating buildings of different ages, construction methods and regulatory requirements. The management of that information becomes particularly demanding during refurbishment programmes, where original drawings may be incomplete and existing installations do not always match available records.
The co-location with elementalLONDON extends these discussions into heating, ventilation, air conditioning, retrofit and energy-efficient building systems.
Refurbishment projects frequently involve difficult decisions about the relationship between building fabric improvements and mechanical or electrical upgrades. Insulation, ventilation, heating capacity and controls must be considered together, particularly where work takes place in occupied buildings with limited plant space or restricted access.
Equipment performance also depends on installation and commissioning. Heating and cooling systems specified against standard test conditions may operate differently when connected to existing distribution networks, while poor controls integration can reduce the benefits of otherwise efficient equipment.
The combined exhibition will include manufacturers such as Carrier, Daikin and Mitsubishi Electric, alongside insulation, fire protection and specialist building product suppliers.
elementalLONDON’s conference programme includes sessions on heat pump deployment, commercial building standards, overheating, building resilience and the practical requirements of low-carbon construction.
The CIBSE Influence Theatre will also examine heat network zoning, embodied carbon in mechanical and electrical installations, and digital engineering for operational optimisation.
Together, these subjects give building owners, designers and contractors opportunities to compare technical approaches across building systems that must eventually operate as a coordinated whole.
The Workforce Behind the Project Pipeline
The government’s Construction Jobs Plan, published on 19 October 2026, provides a national framework for addressing workforce shortages and improving investment in skills and training.
Developed around cooperation between government, employers, local leaders and industry organisations, the plan recognises the need to strengthen entry routes while improving the development and retention of experienced workers.
The Construction Jobs Plan arrives as the sector faces substantial demand for specialist trades, supervisors, engineers and technical professionals across housing, infrastructure and building refurbishment programmes.
Increasing apprenticeship numbers is one part of the response, but construction also depends on experience developed through years of site work, technical responsibility and project management. Experienced supervisors and specialist tradespeople cannot always be replaced quickly, particularly where projects require detailed knowledge of complex installations, temporary works or safety-critical operations.
London Build’s Careers in Construction Hub and Skills & Marketing Stage will address professional development, recruitment, apprenticeships and workforce retention.
A scheduled session on reskilling the construction workforce for modern methods of construction will bring together representatives from the National Federation of Builders and organisations involved in housing construction and skills development.
Other discussions will examine recruitment and retention in an increasingly digital workplace, alongside opportunities for younger professionals and people entering construction through alternative career routes.
The wider networking programme includes events organised with professional associations and industry groups, providing opportunities for employers, training organisations and individuals to discuss workforce development directly.
