Why this suits Hertfordshire
Bi-folds fold the whole opening away, which is why they suit the rear extensions that dominate improvement work in Hertfordshire. Worth knowing: they stack, so you lose the leaf width off the reveal.
Interwar and postwar suburban semis, Victorian stock, and new towns. Sheltered inland. The failure that tends to come first is Sealed-unit failure on 1990s installations and tired hardware — worth knowing before you decide between repairing what you have and replacing it.
A high-value replacement market — slim aluminium and heritage profiles do well. Order to the structural opening, measured in three places, smallest figure wins. How to measure properly.

Bi-fold doors in Hertfordshire — questions
Who notifies building control on a supply-only order in Hertfordshire?
You do. Replacement windows and external doors are notifiable work, and with no registered installer involved there is no FENSA or CERTASS self-certification. If we install, we certify.
Which postcodes does that cover?
Hertfordshire covers AL1, AL10, AL2, AL3, AL4, AL5, AL6, AL7, AL8, AL9, CM21, CM23, EN10, EN11 and 34 more. Anything outside that list is still delivered — it just prices differently.
Is there a minimum order for Hertfordshire?
No minimum on the product. Delivery is priced by area and size of load, so a single unit to Hertfordshire carries a delivery charge that a full house of windows effectively absorbs.
Do you supply trade in Hertfordshire?
Yes. Trade accounts get ex-VAT pricing and the same lead time. Tell us you are trade when you send the sizes.
Do you deliver to Hertfordshire?
Yes. Hertfordshire is 114 road miles from our Birmingham unit, which puts it in Zone C: 2–3 working days once made. Everything is made to your sizes before it goes on the vehicle.
