Water, grid and nuclear clients named teams, signed contracts or bought businesses this week, and big building and civils awards landed on top. Housing went the other way, with the CPA cutting its forecast, housebuilder profit warnings passing the 2008 total and a £1.5bn London scheme shelved.

The week in numbers: 27 news stories, 1 firm gone under this week and 20 so far this year, 99 senior roles open, 32 of them new this week.

Energy and water are where the multi-year work is

Thames Water named nine contractor teams for its £4.8bn AMP8/9 major projects framework. A framework place is not a contract, but it is years of visible pipeline for anyone inside those firms. Portsmouth Water appointed Clancy to a £26.84m pipeline and pumping station contract at Havant Thicket, running to 2030.

The grid is pulling the same way. Balfour Beatty won the first phase of National Grid's Birkhill Wood substation in East Yorkshire, around 200 people at peak once main construction starts in 2027, and Renew Holdings paid up to £50m for the parent of high-voltage cabling firm PBU. In nuclear, SGE UK and Origin Nuclear signed a letter of intent to form an operator for 14 small modular reactors at three sites, while the Public Accounts Committee called Sizewell C's financing a terrible deal that could cost taxpayers up to £47.7bn.

Clients with regulated or ring-fenced money are committing to multi-year programmes, and the firms serving them are spending to get bigger. That matters most to commercial, project and engineering staff in water, power and nuclear, particularly in East Yorkshire, the Thames region and on the south coast.

Housing is turning down, and the Budget only partly answers it

The CPA now expects output to fall 4% in 2026 and grow just 0.4% in 2027, with private housing down a further 3%. Listed housebuilders have issued 14 profit warnings this year, above the 10 recorded in 2008. Landsec shelved its £1.5bn Lewisham redevelopment after a dispute with the council over affordable housing.

The Budget's answer is over £1bn for social housing and new borrowing powers for councils and mayors. That is real money, but it flows through registered providers and councils, not the private sales model that is struggling.

This lands hardest on land, commercial and finance staff at housebuilders and on pre-construction QSs on London mixed-use schemes where viability is being renegotiated.

Big awards keep landing, and so does the cost of winning them

Sir Robert McAlpine beat Bovis and Overbury to the £133m, four-year Bank of England refurbishment, and Bovis was confirmed on the £200m St Giles Quarter office tower in Bloomsbury. West Suffolk NHS Trust disclosed an £837.6m contract with Dragados, and Balfour Beatty, Kier and Aureos start main works on the A66 in November, a £1.5bn scheme now set to run nine years.

Set against that, Mace Construct posted a £61.8m pre-tax loss on £2.3bn of revenue, with chief executive Jason Millett standing down as Mark Reynolds returns to run it. Further down the chain, 45 road and rail contractors collapsed in the nine months to September, up 55% on last year.

The biggest firms win the biggest jobs, the margin is thin, and the subcontractors underneath carry the risk. That matters to commercial managers, QSs and planners at highways and rail subcontractors, and to anyone weighing a move into a tier one on the strength of its order book alone.

Worth your five minutes

My take

Follow the client's money, not the contractor's turnover. This week the clients with regulated or ring-fenced budgets were the ones committing to multi-year work, and the firms serving them were buying businesses to get bigger. Private housing and London mixed-use were being cut, warned on or shelved.

The pattern I see most often is people choosing their next employer by the size of the name on the hoarding. Mace Construct lost £61.8m on £2.3bn of revenue. The question is not how big the business is, but who is paying it and how reliably.

Before your next move, ask what share of the order book sits with regulated or public clients, and how old it is. If you cannot get a straight answer, that is your answer. And if you are carrying that decision alone, this week's question is for you: When you hit a problem you cannot take to your board, who do you actually call?
