Yes, trade buyers can buy from a window fabricator, but most set up a trade account first, and some apply minimum orders and set lead times. A local trade supplier gives the same made-to-measure uPVC windows without the fabricator’s account setup.

What does a trade account usually need?

  • Company or sole trader details and trade proof
  • A credit check or payment on order
  • Accurate size schedules for every order

What should you compare between suppliers?

  • Profile class (Class A under BS EN 12608)
  • BFRC rating for the window
  • Lead time and delivery terms
  • Warranty and how glass breakage is handled

Do you still need certification to fit them?

Yes. Replacement windows in England must comply with Building Regulations, so installers need FENSA or Certass registration or must notify building control. Our trade counter is at Unit 1, Friar Walk, Worthing, with free delivery within 30 miles. Browse our supply-only windows. Ask each supplier how they handle damaged or mis-sized units, as that affects your risk on site and your programme.

So helpful - Steve was so patient while I chose my new front door - which was installed by PBM Exteriors who recommended MLI. I cannot emphasise how much my new and very contemporary front door makes the house look so modern and 'new'. Just huge thanks for great service and an amazing grey anthracite grey front door and side panels!

Thank you Richard.
So pleased I found MLI to supply the windows and doors for my property renovation, Excellent Prices, far more competitive than any other quote I had. Service from Steve & Loretta was amazing, nothing was too much trouble. Everyone compliments us on the fantastic windows. I highly recommend. Thank you so much
