The UK market for commercial glazing has been less buoyant in 2017 as the private commercial sector reacted to the climate of uncertainty surrounding the Brexit process. This resulted in only marginal growth for 2017 and growth rates slowing to 2-3% by 2021.

The commercial glazing sector is particularly reliant on the offices and retail sectors which have both seen reductions in new order values in 2016-17 as expansion and investment plans for some organisations have been deferred. Current forecasts indicate that the market is likely to flatten in 2018-19, followed by modest annual growth rates of around 2-3% to 2021.

Within the commercial glazing market, the largest segment by value is commercial windows, with an estimated share of 56%, followed by curtain wall and ground floor treatments. Roof glazing accounts for the smallest share. The level of demand for ground floor treatments has been affected by structural changes within the retail sector towards online shopping and ‘click and collect’ services, whilst the trend for the grocery multiples to build ‘express’ type outlets has also affected the average value of contracts.

In terms of frame materials, aluminium dominates but timber, PVCu, steel and composites all have reasonable shares and sector strengths.Following the higher levels reached in 2016, the market is estimated to show marginal growth in 2017 with no real growth 2018-19. Trends follow those in key construction markets with office, retail and education construction forecast to weaken during this period.

Jane Tarver of AMA Research said: “Commercial glazing suppliers will continue to derive gains from RMI particularly in those sectors showing lower annual growth in new construction work, such as education and healthcare. Increasing average prices are likely to be a characteristic of the market into the medium-term which will result in some value growth, but with the volume of commercial glazing opportunities likely to decline.”

Key to the medium-term prospects for the commercial glazing market in the UK are the levels of business confidence and investment, which remain uncertain at present and will depend on the outcome of the Brexit negotiation process. In addition, the strength of the private commercial sector construction output will be key, with some regions benefitting from a strong pipeline of work, eg London and the South East, but with other regions likely to be less buoyant.
