The Construction Products Association’s forecasts for UK construction activity have been downgraded once again due to the impacts of continued Brexit uncertainty on investment, divergences between regional housing markets, difficulties faced by traditional high street retailers and concerns over major infrastructure delivery.

The CPA’s latest forecasts anticipate overall construction output falling by 0.4% in 2019, revised down from a forecast of marginal growth of 0.3% in the Winter forecasts. Growth of 1.4% is forecast for 2020, largely driven by activity on major infrastructure projects but also supported by sharp increases in warehouses and ports activity.

The effects of continued Brexit uncertainty adversely affect sectors that require high upfront initial investment: commercial offices and industrial factories. An extended period of falls in new orders in both sectors highlights that uncertainty over long-term returns has made major expenditure on new floor space increasingly difficult to justify. Offices and factories output is forecast to fall 11.0% and 15.0% respectively in 2019, with further falls of 4.0% and 10.0% respectively in 2020.

Despite political and economic uncertainty, consumer spending has remained strong. However, retail construction is still forecast to fall 10.0% each year in 2019 and 2020. Investment in new retail space continues to be affected by the longer-term structural shift to online spending that has led to administrations and restructuring of traditional high street retailers and skewed retail demand towards storage, distribution and logistics facilities. Consequently, industrial warehouses construction is forecast to rise over the forecast period. In addition, prolonged Brexit uncertainty and stockpiling has boosted demand for storage space further and warehouses output is forecast to rise by 15.0% in 2019 and 20.0% in 2020 to a record-high level of activity. This uncertainty also boosts demand in the ports sub-sector, where output is forecast to rise 12.0% this year and 10.0% in 2020.

Private house building activity is expected to remain flat, albeit at a high level, over the forecast period reflecting house builder caution over the slowdown in demand and falling prices in London, as well as parts of the South East and East currently offset by buoyant housing markets of the North West, Yorkshire and the Midlands. In contrast, public housing starts are forecast to rise 2.0% in 2019 and 5.0% in 2020 supported by an increase in building for the affordable market.

The infrastructure sector is expected to experience the strongest growth rates across the forecast period, with growth of 9.3% forecast for 2019 and 9.7% for 2020 even with caution regarding government’s ability to deliver on major infrastructure projects such as Crossrail and HS2. Without this infrastructure growth, the construction industry would experience a 1.8% fall in 2019, followed by two years of stagnation.

Noble Francis, Economics Director at the Construction Products Association said: “It’s a currently a mixed picture for the construction industry and fortunes will depend highly on the sector and region in which firms are working. Those involved in major infrastructure projects, warehouses or ports are enjoying considerable growth but firms working on offices, retail and factories will be experiencing falls in construction activity.

“Brexit uncertainty has had a large impact on sectors dependent upon high upfront investment for a long-term rate of return, especially where the investment is from international investors. It has so far hindered investment in new offices towers, factories and high-end residential and, given a 12-18 month lag between new orders and activity on the ground, output in these sectors will be adversely affected in 2019 and 2020 at the very least.”

The CPA’s forecasts are based on either one of the two most likely options regarding Brexit at this point occurring: a revised version of the Prime Minister’s Brexit Withdrawal Deal is ratified following cross-party discussions prior to 22 May (that would enable the UK to exit the EU on 1 June and enter the implementation period until 31 December 2020 so nothing changes in the near-term) or a further extension so that an alternative deal such as a Customs Union could be agreed upon and prepared for through an extension beyond 31 October.
