The price of a supply-only composite door depends on whether you buy a slab or a full doorset, plus size, glazing, core, finish and hardware, so exact figures come from a quote. Give the opening size and specification and we can price it.

What affects the price most?

  1. Slab only, or a full doorset with frame
  2. Size, design and glazing, including side panels and fanlights
  3. Core and specification, such as foam or timber, declared U-value and PAS 24 certification
  4. Colour and finish, with dual colours and special finishes above standard
  5. Hardware: multipoint lock, cylinder, handles and hinges
  6. Quantity and delivery distance

What does a trade quote usually cover?

  • The slab or doorset and its frame
  • Threshold, hinges and locking, if included in the set
  • Glazing and any decorative glass
  • Delivery

What do I need to give for a quote?

Provide the opening size, door style, colour, hand of opening and any security requirement. Accurate measurements avoid remakes. MLI Building Products supplies composite doors to the trade, with free delivery within 30 miles of the Worthing counter at Unit 1, Friar Walk.

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
