By working closely with our UK manufacturing partner, Conservatory Outlet, we have complete control over our supply chain. This allows us to provide marketing-leading products that stand the test of time.


We’re proactive. We are constantly innovating to ensure that our windows, doors and living spaces lead the way when it comes to style, choice, durability and energy efficiency.

Thanks to the strong relationship we have with Conservatory Outlet, the products and designs we offer are the best available. And they’re only available to ERG customers – you simply won’t find a like-for-like offering anywhere else.

Training is provided to everybody and every employee is supported by an ongoing improvement plan to help people realise their potential and be the best in their respective fields.

We are committed to supporting the development of our staff and this is reflected in our apprenticeship programmes that give the next generation a head start in their careers with us.

UK Manufacturing Craftsmen


Conservatory Outlet recently invested over £1m in new technology and machinery to further improve the finish of every product that leaves its factory.

This is combined with an ongoing plan to elevate its manufacturing processes. Like us, they never stop still in the search of perfection.

We are an environmentally conscious company, and this extends throughout our supply chain. We ensure that we minimise our carbon footprint where possible and recycle at every stage of the manufacturing and installation processes.

By working with UPVC and aluminium, we’re able to capture and recycle all the offcuts and waste and prevent items from ending up in landfill.
