Delivery across Cornwall
For Cornwall, delivery is to your site, yard or unit. Tell us about any access limits, such as weight restrictions or narrow streets, so the right vehicle is booked.
Building regulations in England
Replacement rooflights and roof lanterns in England should meet a U-value of 2.2 W/m²K under Approved Document L. A lantern in a new extension is covered by the extension's own building regulations approval. Replacing a glazed or polycarbonate conservatory roof with a solid roof usually takes the conservatory out of the exemption, so building control approval is normally needed.
Before anything goes into production you get a written order acknowledgement with sizes, finishes and handing for every item. Check it carefully, because made-to-measure items cannot be returned if the sizes were wrong.

How do I get trade prices for Cornwall?
Send your schedule through the quote form or by email, and apply for a trade account if you do not already have one.
Can I walk on a flat rooflight?
Only if it is a walk-on unit designed for it. Tell us if you need one.
Why does a flat rooflight need a fall?
So rainwater runs off instead of sitting on the glass. The upstand or the unit provides the slope.
