Construction new orders in Great Britain fell 11.8%, or £1.232 billion, in the second quarter of 2026, following a 10.5% fall in the first quarter, according to the Office for National Statistics. Yet construction output still increased 0.3% in Q2, leaving contractors working through existing projects while the flow of replacement work weakens.
That divergence is now becoming a tendering issue. The BCIS Tender Price Index panel found 67% of respondents regarded contractors as eager to tender in Q2, while separate BCIS analysis said competition was intensifying as the flow of new work slowed. At the same time, the government's All Work construction material price index was 6.0% higher year-on-year in June.
For estimators and commercial teams, the risk is straightforward: winning work becomes harder when fewer orders are entering the market, but cutting the tender too aggressively can leave little protection against costs that move between pricing the job and actually buying the labour, materials and subcontract packages.

UK Construction Tendering: The Numbers Behind the Pressure
| Market Indicator | Latest Position | Why It Matters to Tendering |
| Construction new orders, Q1 2026 | -10.5% | First consecutive quarterly fall in 2026 |
| Construction new orders, Q2 2026 | -11.8% | £1.232bn quarterly reduction |
| Construction output, Q2 2026 | +0.3% | Existing workload is still being delivered |
| Contractors described as eager to tender | 67% | BCIS TPI panel, Q2 2026 |
| BCIS All-in Tender Price Index | +3.2% YoY | Tender pricing remains relatively restrained |
| All Work material price index | +6.0% YoY | Underlying material pressure is higher than headline tender-price growth |
| Fabricated structural steel | +17.7% YoY | Shows why package-specific exposure matters |
The first distinction is crucial. New orders are not the same thing as construction output. The ONS new-orders series measures contracts awarded for new construction work and provides a forward-looking indicator of future workload. Output records construction currently being delivered. The official ONS Q2 construction release therefore shows an industry that can remain active on site while simultaneously seeing fewer new contracts entering the pipeline.
Every Major New-Order Sector Fell in Q2
The weakness is broad on a quarterly basis. BCIS analysis of the ONS dataset shows that no major sector recorded an increase in new orders between Q1 and Q2 2026.
| Sector | Q2 vs Q1 2026 | Q2 2026 vs Q2 2025 |
| Public housing | -2.1% | -19.1% |
| Private housing | -3.7% | +12.9% |
| Infrastructure | -5.1% | -22.5% |
| Public other new work | -22.0% | -45.8% |
| Private industrial | -10.1% | +33.1% |
| Private commercial | -21.0% | -28.5% |
| All new work | -11.9% | -18.1% |
The 11.9% figure in the sector table is the BCIS presentation of the underlying ONS dataset, compared with the ONS bulletin headline of 11.8%. The small difference is a rounding presentation rather than evidence of two different market movements.
Private commercial and public other new work were the largest contributors to the latest quarterly decline. The annual picture is more mixed: private industrial orders were 33.1% higher than Q2 2025 and private housing was 12.9% higher. This is therefore not evidence that every part of UK construction is collapsing.
What it does show is that a contractor's experience depends heavily on the sector in which it is competing. An estimator pricing commercial building work can face a very different tender market from a contractor exposed to power, water, data centres or another stronger infrastructure segment.
Busy Today, But What Replaces the Current Job?
The most important market signal may be the gap between orders and output. Construction output grew 0.4% in Q1 and another 0.3% in Q2. New orders moved in the opposite direction, falling 10.5% and 11.8% respectively. Infrastructure new work output actually increased 1.9% in Q2 despite infrastructure orders being lower. There is no contradiction. A contractor can be busy pouring concrete, installing services and submitting monthly valuations on projects secured months or years ago while its estimating team sees fewer attractive opportunities replacing that work.
LCM identified the same distinction in its analysis of UK construction financial distress and insolvencies. Planning pipelines, frameworks, tender opportunities, contract awards, construction activity and cash received by the supply chain are different stages and should not be treated as interchangeable evidence of workload. For a commercial team, the practical question is not simply whether the business is busy this month. It is how much secured work replaces projects as they complete over the next 12 to 24 months.
Tender Competition Is Increasing, But There Is No Reliable Bidder Count
The evidence of harder competition is stronger than anecdotal LinkedIn frustration, although one important limitation remains. The BCIS Q2 Tender Price Index panel found 67% of respondents considered contractors eager to tender. A separate BCIS assessment said “competition intensifying as the flow of new work slows”.
Gardiner & Theobald's Q2 market intelligence reaches a similar conclusion. It reports softer demand, delayed project conversion and increased competition for workload restraining pricing, while contractors remain exposed to higher fuel, energy, shipping, metals and risk costs. However, there is no comprehensive public UK dataset showing that the average tender has moved, for example, from four bidders to seven bidders during 2026. LCM therefore does not claim a national increase in bidders per tender. The hard evidence is lower new orders, high contractor appetite to tender and professional market commentary reporting stronger competition.
Are Contractors Already Cutting Their Margins?
This is where the evidence needs more care. It would be tempting to conclude that fewer orders automatically mean collapsing contractor margins. The available evidence does not support that as a universal statement. Gardiner & Theobald says main contractor overhead and profit remains broadly stable, with current pricing pressure appearing more through preliminaries, package rates, risk allowances and supplier notifications. It also reports contractors willing to fix prices or absorb short-term volatility where pipelines are thin and projects provide credible forward workload.
Large contractors can also be performing well despite the weaker national orders picture. Balfour Beatty reported a 3.4% profit-from-operations margin in UK Construction for the first half of 2026, compared with a reported 3.6% in the first half of 2025. Its wider order book remained £22.9 billion. That matters because the present risk is more subtle than a simple industry-wide “race to the bottom”. Contractors with strong balance sheets, specialist positions or secured framework workloads may continue protecting margins. Others operating in weaker sectors may have more incentive to price competitively to maintain utilisation and overhead recovery.
What cannot be established from public data is how many contractors are deliberately “buying work”. LCM would need company-level tender and cost information to make that claim, and that information is generally private.
The Bigger Estimating Risk: Price Today, Procure Later
An estimator does not normally buy every package on the day the tender is submitted. Between tender return and actual procurement can sit clarification, negotiation, contract execution, design development, mobilisation, subcontract tendering, technical approval and the procurement programme itself. Different packages are then bought at different stages. There is no reliable UK-wide public statistic for the average tender-to-procurement period, and there is no universal supplier quotation-validity period. Those numbers should come from the actual procurement programme and the actual quotation being relied upon, rather than an industry rule of thumb.
This matters because official material movements are now highly uneven. The latest government data shows the All Work material index 6.0% higher year-on-year, but fabricated structural steel was up 17.7%, rigid pipes and fittings 12.0% and the aggregates-related index 11.4%. Ready-mixed concrete was down 1.1% and cement down 4.5%. LCM's detailed UK construction material price analysis shows why applying one generic inflation percentage across an entire tender can materially misstate the risk.
| Material | 12 Months to June 2026 | Tendering Implication |
| Fabricated structural steel | +17.7% | High exposure where price is not secured early |
| Rigid pipes and fittings | +12.0% | Relevant to services and building-product procurement |
| Gravel, sand, clays and kaolin incl. levy | +11.4% | Civils and delivered-material exposure |
| Ready-mixed concrete | -1.1% | Shows why the headline 6% cannot be applied universally |
| Cement | -4.5% | Another material moving opposite to the headline index |
LCM Tender Test: How Quickly Can Inflation Remove the Profit?
The useful calculation is not “what is construction inflation?” It is:
How much of this tender remains exposed when prices move, and how large a cost increase would remove the profit allowance?
LCM can express that as a simple sensitivity calculation:
Margin wipe-out threshold = target profit margin ÷ exposed cost share
Consider an illustrative £10 million tender carrying a 2.5% target profit allowance. The expected profit is £250,000. Assume, purely for sensitivity testing, that £4 million — 40% of the contract value — remains commercially exposed to future cost movements and that no contractual mechanism allows those increases to be recovered.
| Increase on £4m Exposed Cost | Additional Cost | Profit Remaining | Original Profit Eroded |
| 1% | £40,000 | £210,000 | 16% |
| 2% | £80,000 | £170,000 | 32% |
| 4% | £160,000 | £90,000 | 64% |
| 6% | £240,000 | £10,000 | 96% |
| 6.25% | £250,000 | £0 | 100% |
The important number is not 6.25% itself. That percentage changes with the margin and the proportion of the contract that remains exposed. The important finding is that a relatively modest movement on part of a contract can consume a much larger percentage of the profit on the whole contract.
| Exposed Share of Contract | Cost Increase Needed to Erase a 2.5% Margin |
| 20% | 12.50% |
| 40% | 6.25% |
| 50% | 5.00% |
| 60% | 4.17% |
| 80% | 3.13% |
Methodology warning: this is a static sensitivity model, not an assumed cost structure for a typical UK project. Actual exposure reduces as packages are bought out and varies materially by design, procurement route, programme, quote validity, contract amendments and supplier agreements. A project with 20% unprocured exposure has a completely different risk profile from one with 80% still open.
How Estimators Can Calculate Procurement Inflation Properly
The better approach is to calculate exposure package by package rather than apply one national inflation allowance to the contract sum.
| Estimator Check | Question to Answer |
| Current base cost | What is actually included in the supplier or subcontract quotation? |
| Quote validity | On what exact date does that price expire? |
| Procurement date | When does the programme require the package to be bought? |
| Cost driver | Is the package driven mainly by steel, labour, copper, energy, fuel, imported equipment or another input? |
| Escalation assumption | What evidence supports the assumed movement between pricing and procurement? |
| Price security | Can the supplier lock the price, and under what conditions? |
| Contract allocation | Can inflation be recovered or is the contractor carrying it? |
| Tender exposure | Forecast procurement cost minus current included cost |
| Margin test | How much of the expected profit would that exposure consume? |
In simple terms:
Forecast procurement cost = current cost × expected movement over the relevant procurement period.
Commercial exposure = forecast procurement cost − cost included in the tender.
The estimator can then aggregate the package exposures and compare them directly with the project's risk allowance and expected profit. That calculation is more useful than adding 6% to everything simply because the national All Work materials index is currently 6% higher. A concrete package, steel frame, electrical package and internal fit-out package do not have the same price drivers or procurement dates.
Fixed Price Does Not Mean the Cost Stops Moving
Contract terms then determine who ultimately carries the movement. Where a contractor agrees a fixed price without an applicable inflation-adjustment mechanism, future cost movement may remain with the contractor, subject to the detailed contract and amendments. JCT contracts can include fluctuations provisions, while NEC contracts can include price-adjustment mechanisms such as Option X1 where selected. The commercial point is not that one form is inherently safer. It is that the estimator needs to know whether the risk being modelled can be passed through, shared, fixed with the supply chain or must sit inside the tender.
Why Tender Prices Can Stay Low While Some Costs Rise Faster
BCIS estimated its All-in Tender Price Index increased 3.2% in the year to Q2 2026. The government All Work material index was meanwhile 6.0% higher in the year to June. Those percentages should not simply be subtracted and labelled a 2.8 percentage-point loss of contractor margin. The indices measure different things. Tender prices include a much broader mix of labour, subcontracting, preliminaries, overhead, profit and risk, while the materials index measures material-price movements.
But the direction remains commercially significant. BCIS says low activity is offsetting inflationary pressure on inputs, while Gardiner & Theobald says softer demand and competition are restraining tender pricing even as selected packages face renewed cost pressure. That is precisely the environment in which winning a tender and making money from the tender can become two different achievements.
What Happens to Tender Prices in 2027?
Current forecasts do not point to one universal UK construction inflation number next year.
| 2027 Forecast | Tender Price Inflation |
| Gardiner & Theobald UK average | 2.75% |
| Gardiner & Theobald Greater London | 3.0% |
| Turner & Townsend UK real estate | 3.5% |
| Turner & Townsend UK infrastructure | 5.0% |
The forecasts themselves demonstrate the danger of one blanket escalation allowance. Sector, region, programme, procurement route and package mix matter. LCM's latest analysis of UK tender prices and construction costs heading into 2027 also identifies energy and geopolitical volatility as an additional risk, particularly for projects with long procurement programmes and energy-intensive materials.
UK Construction Tendering 2026: Quick Answers
Why are construction tenders becoming more competitive?
New orders fell in both Q1 and Q2 2026, reducing the flow of replacement workload in parts of the market. BCIS found 67% of its Q2 TPI panel respondents regarded contractors as eager to tender, while BCIS and Gardiner & Theobald both report increasing competitive pressure. There is, however, no public national dataset showing the precise average number of bidders per job.
How much did UK construction orders fall in Q2 2026?
The ONS reported an 11.8% fall in total construction new orders in Great Britain between Q1 and Q2 2026, equivalent to £1.232 billion. BCIS reports the underlying dataset as an 11.9% quarterly fall and an 18.1% annual fall.
Does 6% construction material inflation mean estimators should add 6% to every tender?
No. The 6.0% figure is the All Work material price index. Individual products are moving in different directions: fabricated structural steel was up 17.7% while ready-mixed concrete was down 1.1% and cement down 4.5%. Labour, plant, subcontract packages and tender prices are separate measures again.
How much cost inflation would wipe out a 2.5% tender margin?
It depends on how much of the contract remains exposed. If 40% of the contract remained unprocured, a 6.25% increase across that exposed value would equal 2.5% of the total contract value. If 80% remained exposed, only a 3.13% adverse movement would have the same effect. These are sensitivity calculations, not predictions.
Should an estimator price using today's material costs?
Today's quotations remain the starting evidence, but the estimate should also identify when each package will actually be procured, when the quotation expires, whether the price can be secured and what evidence supports any escalation allowance through that period.
Are UK contractor margins already collapsing?
The available evidence does not support a universal claim that main contractor margins are collapsing. Gardiner & Theobald reports broadly stable main contractor overhead and profit, while major contractors such as Balfour Beatty continue to report positive UK Construction margins. The more immediate risk is competitive pricing limiting the ability to pass future cost increases through to clients.
LCM Analysis: Do Not Win the Job You Cannot Afford to Build
The Q2 orders figure is important, but the 11.8% fall is not the whole story. The more useful commercial signal is the combination of falling replacement orders, strong appetite to tender, restrained tender-price growth and highly uneven input costs.
That combination can create exactly the wrong incentive. A contractor sees fewer opportunities, competes harder to secure the next job and removes risk allowance to make the tender competitive. The project is then awarded, but several major packages remain unprocured. By the time those packages are bought, today's supplier quotations have expired and part of the market has moved.
That sequence does not automatically create a loss. Early procurement, supplier price locks, alternative specifications, productivity gains, contractual inflation mechanisms and stronger buying power can all reduce exposure. But the risk needs to be calculated before the margin is cut, not discovered six months after winning the contract.
Methodology and Data Limits
This LCM analysis uses ONS construction output and new-order data, BCIS tender-market evidence, Department for Business and Trade construction material indices, Gardiner & Theobald and Turner & Townsend tender-price forecasts, and published contractor financial results. New orders, construction output, material inflation, tender-price inflation and company operating margins measure different things and have deliberately not been combined into a single artificial index.
There is no public UK-wide 2026 dataset identified by LCM that provides a reliable average number of bidders per tender, a universal supplier quote-validity period or a standard tender-to-procurement duration. Those variables must therefore be established from the actual project rather than invented as national assumptions. The £10 million tender example is a sensitivity model only. The 2.5% target margin and 40% exposed value are illustrative inputs selected to demonstrate the mathematical relationship between margin and unprocured cost exposure. They are not presented as averages for UK construction projects.
What Happens Next
The next ONS construction release is scheduled for 11 September 2026. The key question will be whether the gap between current output and future workload begins to narrow, or whether contractors continue delivering existing order books while the replacement pipeline remains weak. For anyone pricing work now, the commercial discipline is already clear: know what remains unprocured, know when it will be bought, know when today's quotation expires and calculate how much adverse movement the tender margin can actually absorb before submitting the price.
