Operational review continued
UK Construction continued
Further demand in UK energy and defence
markets continued
In June, the UK Government released the
Strategic Defence Review, declaring defence as
an engine for growth, which will boost prosperity,
jobs and security for people across the UK and
called for a new partnership with industry, including
improved contract management, faster delivery
and a move to industry-standard construction
methods. This alignment with Balfour Beatty’s
capabilities, and the Group’s experience in
defence infrastructure and high-security
environments, means it is well placed to support
the UK Government’s objectives in this sector.
Balfour Beatty’s approach to growing its UK
defence market share includes winning further
work for both the Defence Infrastructure
Organisation, whose projects tend to be security
classified, and at Defence Nuclear Enterprise
(DNE) sites. In 2025, the Group’s live projects at
DNE sites included the Hub at AWE Aldermaston
and the expansion work at Rolls-Royce’s site in
Raynesway, Derby, needed to meet the growth
in demand from the Ministry of Defence and as a
result of the AUKUS agreement. During the year,
Balfour Beatty was selected by Rolls-Royce for a
second project of works at Raynesway, which
will see the Company deliver the critical nuclear
licensed infrastructure required to support the
client’s manufacture of fissile components for
the Royal Navy’s submarine propulsion systems,
and the new AUKUS submarines. Further major
DNE construction frameworks are currently being
pursued in 2026.
Transport remains an important component of
the UK Government’s growth plans and, while
fiscal headwinds are impacting the volume of
activity in the short term, support for major
infrastructure projects such as the Lower Thames
Crossing road scheme and rail projectssuch as
Northern Powerhouse Rail, theTranspennine
Route Upgrade and East West rail was reaffirmed
in 2025. The Government hasalso publicly
backed the expansion plans for Heathrow Airport.
National Highways’ draft third Road Investment
Strategy (RIS3), which includes £25 billion of
funding over five years and is due tobe finalised
imminently, has an increased focus on maintenance
and renewals rather than new roads while,
outside of HS2, the majority ofUK rail funding
inthe short term is also focused on operating,
maintaining and renewing the core railway.
Given Balfour Beatty’s strong market positions
and range of capabilities in the construction and
maintenance of roads and railways, and its
experience in airport construction, the Group
continues to see UK Transport as a growth area
in the medium term. The Lower Thames Crossing
road scheme, a project which the Group was
awarded £1.2 billion of work for in 2023 but has
yet to start the main works contract, was granted
a further £891 million of public funding in 2025
and NISTA are developing a private finance solution
to fund the project to completion. HS2 will continue
to be a material project for Balfour Beatty for the
foreseeable future, and following a pause caused
by a legal challenge, the c£200 million A57 Link
Roads scheme, delivering two new strategic
highways links between Manchester and Sheffield,
is expected to proceed in 2026. With the Group’s
depth of capabilities across transport construction
and maintenance, including asset management
across regional as well as national infrastructure
projects, Balfour Beatty is well positioned to play
a significant rolein the delivery of the UK
Government’s transport strategy.
Strong operational delivery takes PFO margin
above 3%
In 2025, Balfour Beatty’s UK Construction division
delivered an improved PFO margin for the fifth
year in a row and surpassed its long-standing 3%
margin target. This ongoing margin expansion is
built on a track record of strong operational
delivery and a portfolio of higher-quality and
lower-risk projects, overseen by the Group’s
disciplined and rigorous bidding process.
Balfour Beatty’s ambition to provide industry-leading
project delivery across the UK Construction
portfolio not only drives margin performance, but
also demonstrates the Group’s capabilities and
standards, thereby aiding the pursuit of future
work. This focus on project delivery, alongside
the disciplined bidding and strong client demand,
has contributed to the forward order book growing
by 44% in 2025, while remaining heavily weighted
towards lower-risk contract forms. As such, 88%
of the £8.9 billion order book is contracted on
target cost or cost plus incentivised fee terms,
while the remaining 12% is weighted towards
two-stage fixed-price contracts, which are
inherently lower risk than one-stage fixed-price
arrangements. The Group remains focused on
ensuring that new work is contracted on the
appropriate contractual terms and conditions for
the risk undertaken, in order to protect the
Group’s margin and reduce the loss-making
portion of the project portfolio.
On the UK’s largest infrastructure project, HS2,
Balfour Beatty and its joint venture partners are
delivering the main civil engineering works for the
Area North section and the new station at Old
Oak Common in London. On Area North, the
Balfour Beatty VINCI joint venture completed civil
engineering work on the 1-mile Long Itchington
Wood twin-bore tunnel as well as achieving tunnel
breakthroughs at both bores of the 3.5-mile
Bromford Tunnel. In addition, it successfully
pushed the 4,600-tonne M6 South Viaduct east
deck over the M6, with the final stage achieved
without closing the motorway. AtOld Oak Common,
the Balfour Beatty VINCI SYTRA joint venture has
installed over 70% of the first high-speed platform
slabs and commenced blockwork and mechanical
and electrical module installation. At the new
Hinkley Point C nuclear power station, good
progress continues to be made on the underground
marine works and the 230-tonne triple point shaft
formwork structure was lowered and installed
40metres underground to connect the three
tunnels. The Group is also part of the MEH
Alliance, which is delivering the mechanical,
electrical and HVAC installation at the power
station, with volumes increasing during the year.
The Major Highways team achieved substantial
completion of the major improvement scheme at
the interchange between Junction 10 of the M25
and the A3, with traffic management lifted in line
with scheduled expectations. The team also
completed its work on the National Emergency
Area Retrofit scheme, providing emergency
refuge areas on the M25, M3 and M4 and
enhancing safety on the network. Work began
during the year on the M3 Junction 9 scheme,
injoint venture with VolkerFitzpatrick, with
enabling works, piling and earthworks delivered
to facilitate significant structural works in 2026,
while the A63 project is on track to open to traffic
in the first half of 2026, with strong delivery in
2025 on major structural elements, such as the
underpass tunnel and pumping station.
UK Construction operates across the length and
breadth of Great Britain, delivering hundreds of
diverse projects. During 2025, the business installed
the first new bridge over the River Trent in
Nottingham for 65 years, commenced construction
on the new Nairn Academy school in the Scottish
Highlands and delivered restoration works on the
historic Riddings Viaduct, a Victorian structure
that spans the Anglo-Scottish border. Beyond the
new Rolls-Royce and power station contracts,
other projects added to the UK Construction
order book during 2025 included the
