The Building Envelope

bricks and roof tiles

Our factories maintain good stock levels and delivery lead times, merchants and distributors are turning to Crest to help them through these challenging times.  

The construction material shortage remains challenging for building and construction businesses as demand outstrips supply. With little improvement in the availability of many key building materials, such as timber, bricks and roof tiles, and with suppliers’ delivery times increased sharply as the supply chain works hard to keep up.

Crest’s manufacturing partners have been actively increasing the supply to merchants, distributors and housebuilders to help remove the tremendous pressure they all face. We have adequate production capacity and the ability to manufacture more bricks and roof tiles to further help the supply shortage.

Part L

Changes to Part L have significant ramifications for new build – but also replacement programmes. We report...

The Government is expected to unveil its interim update to Part L next month [Oct]. Stopping short of the far more comprehensive changes to follow in 2025 ,with the introduction of the Future Homes Standard, they nonetheless have significant ramifications for new build and refurbishment programmes – including windows and doors.

John Duckworth, Head of Sales, Commercial, Deceuninck, explains: “The Ministry of Housing Communities and Local Government (MHCLG) is expected to publish its revision of Part L in this October, coming into effect in England and Wales from July next year.

“While it doesn’t go anywhere near as far as the Future Homes Standard, its ramifications are significant for new build and refurbishment projects, pushing up minimum standards at a time when COVID-related supply chain disruption is already pushing up costs and disrupting delivery.

“Planning now to take out the guess work is critical.”
