Origin informed the Court all of my 12 windows have to be removed from the wall to prove none have the serial numbers and the installer informs me that that will invalidate his 10-year warranty “Origin states “he has not removed his windows from the wall, he therefore cannot be sure the serial number plate is not in place and simply hidden. Perhaps they can tell me and the Court where in my T&Cs it says that I may have to remove my windows to get to the serial number? This statement was followed by the statement of truth! In one email Origin said “there will be at least one window with the serial plate on. Have you checked all the opening windows? In another “can I ask for you to check the areas below outlined [opening windows] which shows where the serial number plate would be located on your windows – If you do not have any top openers as in the diagram, the plate will be located within one of the inside sashes. Please check carefully, you may wish to use a torch for clearer visibility.” They forgot to add if all fails, I should use a bulldozer to reap the windows from the wall and I may find the serial numbers. Isn’t Origin’s statement to the Court dishonest and a breach of contract? T&Cs do not refer to removing windows to check the serial number. T&C states, "Origin shall be under no liability under this Warranty if the products are not clearly marked as Origin Goods and carry an Origin serial number" and “the information required in the Warranty Claim Form must include the unique serial number for your Product." My windows came without the serial numbers. Neither Origin nor the installer, Insulating Windows, can provide an explanation, just excuses. Insulating Windows has never denied removing the serial numbers but provided numerous excuses and theories-see below and they vary by the day depending on their mood: i "I can honestly say that we have never been asked for a window serial number in over thirty-five years of fitting they stick them to the sides of the frames, so they tend to be installed with the windows! “In other words, the number is buried in the wall, so the guarantee is void. ii. “I am sorry, but we do not have the serial numbers for the windows. If they are attached to the frames, they will still be on them” (despite me confirming there are no serial numbers, and they did not volunteer to come and check because they knew the numbers were not there and for the record neither did Origin). iii. “Yes, they often attach the labels to the sides of the frames. However, we have never been told that it is necessary to keep these labels. They tend to get installed with the windows. As I say, we have never been asked for a serial number, in over 35 years of installation and 10 years of installing Origin windows.” So, after installing Origin windows for 10 years, they do not know the significance of the labels / serial numbers nor the location of these on the frames (just like Origin staff) and they removed the labels because Origin did not ask them to retain them. Breach of contract/contract is void. Fraud? iv. “I’ve just spoken to our service team [at Origin] about this [and they state] “The windows do not have an EF number like our doors do so don’t have “serial” numbers on them as such. [here we are told by Origin that it does not issue serial numbers at all for windows, but their T&Cs insist on having the unique serial number without which the warranty is null and void! In its defence filed at Court, it says they operate under ISO & all customer-facing documents must be reviewed and updated. So why the conflicting messages and inconsistency bordering on dishonesty? Both companies are happy to insult their customer's intelligence and now the Court. I am sure the Court will be very impressed with Origin’s statement that windows must be removed from the frame to look up the serial number. v. “As stated in the email you have highlighted, unless Origin did forget to apply the serial numbers to the windows, the serial number is likely to be on the sides of the frames, which, to my knowledge, is where Origin put them [that is not what Origin say on its website – installer has no clue!]. Therefore, you will need to remove the window to get to the serial number. This will, of course, invalidate the installation guarantee provided by Insulating Windows Limited.” They are implying Origin did not put the labels. Origin told me "Each Origin product will have a silver plate or sticker which contains the serial number. This serial number allows us to identify which trade partner has supplied the set." False. Origin, in the Court statement, states (a) that if a manufacturing defect claim were to be made by me, they wholeheartedly confirm it would be honoured as Origin's reputation is founded on this integrity. No acknowledgement of any of the above and the fact that a huge percentage of its customers are totally dissatisfied. Origin says it is a “reputable company”! Don't bother buying Origin products.
