COVID-19 Notice – Business ‘Not Quite As Normal’ Update 19/01/2021

We now have all of our valued staff back at work, so we are operating at full capacity in both the office and factory. Staff are strictly adhering to government guidelines with regards to social distancing and other safety measures relating to Coronavirus.

Our supply chain has remained resilient and we are receiving regular deliveries from both Rehau & Smart Systems. Our current lead times for UPVC is 2-3 weeks and Aluminium is 4-6 weeks for most orders.

For inquiries it is still essential that you send them into the main email addresses:



The showroom is the only point of entry to any factory or office unless it is allowed by an allotted member of 1st Class staff. All showroom visits must be booked with a member of staff if you feel they are necessary. We welcome customers back into the showroom, but to socially distance we must insist on timed appointments only and masks must be worn. We can offer zoom calls and virtual showroom appointments are prefered.

The showroom & factory will be closed on Saturdays until further notice. Any trade customers wanting to collect goods need to call in advance and we can put jobs out on a Friday afternoon. If collection is only possible on a Saturday, we will offer this service by appointment only.

All the best,

1st Class Window Systems

Established For Over

20 Years

1st Class Window Systems Ltd was established in 1995 by Paul Trigwell on our present site in Westham – on the outskirts of Eastbourne, in East Sussex and the goal was to manufacture uPvc to a high standard using Rehau profile and top quality hardware. We aim to give a more personal service and the backup of knowledge that the customer expects.

The aluminium department opened in 2013 with the same principles applying and using Smart systems aluminium extrusions, who like Rehau, are a well established often specified system.


Our Investment In


Here at 1st Class we have always believed that ‘a workman is as good as his tools’, and to that end we reinvest heavily in machinery for our factory and our staff to equip them with the best to achieve a consistent quality finish.

We provide a delivery service that covers all the South East including Kent, up to London and over to Hampshire and beyond by arrangement.
