The effects of the Covid-19 global pandemic have seen devastating consequences for individuals, families and businesses all over the world. Throughout this time, we have remained operational and have been working hard to ensure our employees have been working safely and in-line with Public Health England guidance. However, given the significant shift in construction activity over the course of the final days of March, we have now taken the unfortunate decision to close our operations for a period of 3 weeks, effective April 01st, targeting to re-assume our operations as normal by April 22nd.

During this period of closure, our non-manufacturing teams will still be on hand to support you with any question, concerns or advice that you need and we are still handling sales enquiries and issuing quotes remotely.

Please contact us the normal way or through or by emailing:

We will endeavour to come back to you as soon as we can.
