Commercial Property as we approach Q4 2026: What Are the Trends Telling Us?
As we approach the final quarter of 2026, it seems a good time to look back at the year so far and consider what some of the underlying data might be telling us about the commercial property market.
It has already been an eventful year. Continued geopolitical uncertainty, movements in global energy and commodity markets, changing interest rate expectations and wider economic pressures have all played their part. Against this backdrop, the UK construction market has faced an interesting combination of softer activity and continued cost pressures, while climate-related risks are also creating further considerations for property owners and investors.
Many of these pressures are interconnected. Changes in energy and commodity prices, supply chains and the wider global economy can quickly feed through into the cost of materials, transportation and ultimately the delivery of construction projects. Looking beneath the wider economic headlines can therefore give us a useful indication of what commercial property owners and investors may be facing.
So, with three quarters of the year almost behind us, what does the data actually tell us – and what might some of these trends mean for commercial property investment and capital allowances going forward?
Construction activity may be down, but costs are still rising.
While total construction output showed modest quarterly growth in Q2, the picture for new work remains challenging. BCIS data shows that new construction orders fell by 11.9% between Q1 and Q2 2026 and were 18.1% lower than the same period a year earlier. Private commercial new orders were down 28.5% year-on-year.
Despite this softer demand, costs have continued to move in the opposite direction. The BCIS All-in Tender Price Index recorded annual growth of 3.2% in Q2 2026, while construction material prices for ‘Other New Work’ were 6.8% higher in June 2026 than a year earlier.
Looking beneath these headline figures shows even greater variation, with the cost of individual materials and building components moving at very different rates.
This is unlikely to be purely a short-term consideration either. Current forecasts suggest building costs to increase by 13.1% over the five years to Q2 2031, with tender prices forecast to rise by 15.5% over the same period.
The changing demands on commercial property
Cost isn't the only trend worth watching. The demands being placed on commercial property are also continuing to evolve.
Weather-related events and the resilience of the UK's existing building stock remain increasingly relevant, with insurers paying out £1.2 billion for weather-related property claims during 2025 – an increase of 14% compared with the previous year.
For commercial property owners, however, the implications extend beyond insurance premiums and reinstatement values. Changing environmental conditions, alongside evolving occupier expectations and building requirements, are likely to influence how existing properties are maintained, refurbished and adapted over time.
For some properties, this may mean greater investment in areas such as cooling and ventilation, electrical infrastructure, heating and hot water systems and wider building services. For older commercial stock in particular, keeping pace with these changing requirements may involve not simply maintaining existing installations, but upgrading or replacing them altogether.
So, where do capital allowances come into this?
This potential shift from simply maintaining existing buildings towards upgrading and replacing their systems creates a clear capital allowances consideration.
There is a particularly relevant link to integral features expenditure. Electrical systems, heating and hot water systems, air conditioning and ventilation are all fundamental to how a modern commercial property operates and are also areas in which owners may increasingly need to invest as existing building stock ages and requirements change.
The underlying cost data is important here too. Costs are not moving uniformly across a project: individual materials, systems and components can experience significantly different rates of inflation. A refurbishment may therefore have a single headline cost, but that figure alone tells us relatively little about the expenditure sitting underneath it.
For property owners undertaking refurbishment, replacement or modernisation works, understanding that underlying expenditure is important. Where costs relate to qualifying integral features, capital allowances can provide tax relief against that investment, meaning the headline project cost and its true net cost after tax relief can look quite different.
What about commercial property acquisitions?
The same trends are also relevant to the second-hand commercial property market.
As the requirements placed on buildings evolve, investors may increasingly find themselves comparing properties at very different stages of their lifecycle. A modernised property with upgraded building services may command a greater premium, while an older property may be acquired at a different price point but with the expectation that significant capital expenditure will be required to bring it up to the desired standard.
From a capital allowances perspective, both scenarios warrant consideration. An existing commercial property may already contain significant qualifying plant and machinery embedded within the purchase price and, depending on the property's history and the relevant fixtures requirements, allowances may be available to the purchaser.
Where refurbishment or replacement works are subsequently undertaken, this creates a further layer of expenditure to consider. The allowances potentially available within the acquisition and those arising from subsequent capital expenditure are separate considerations and should be reviewed accordingly.
The variation in construction costs seen throughout 2026 also reinforces the importance of robust valuation. Different building systems and components are experiencing very different movements in cost, while their age, specification and condition will vary from property to property. Construction and reinstatement data does not determine a capital allowances valuation, but it does reinforce why a property-specific, evidence-based approach remains important.
Looking ahead
There is no single trend that defines commercial property in 2026.
What the underlying data does show, however, is an evolving relationship between what we require from our buildings, the cost of providing it and the investment needed to keep existing stock relevant. For owners, that may mean greater expenditure on maintaining, replacing and modernising existing assets. For investors, it may mean paying a premium for properties where that investment has already taken place or acquiring assets knowing that further capital expenditure will be required.
In either case, understanding the headline purchase price or project cost is only the starting point. As commercial property continues to evolve, looking beneath that figure – at the individual assets, systems and expenditure involved – will become increasingly important.
Capital allowances form part of that wider investment picture, helping owners and investors understand not simply what a property or project costs, but its true net cost once the available tax relief is taken into account.
