Oak cill

I ordered two of these (due to not measuring twice-d’oh!) and both were of excellent quality, and arrived extremely well packaged and un-damaged. 100% recommended, will use again.

Always a pain to have to order twice for the same job, but at least you're happy with the Oak and hopefully you managed to make use of the other piece elsewhere!

Thanks for uploading a photo Nick, always appreciated. Love the wall colour too :)

Suspect delivery

No problem whatsoever with product. Exactly what I ordered and - thankfully - extremely well packed. However delivery dreadful. Delivery assured Tuesday, then Wednesday, then Thursday. I suggest you change you carrier.

Thanks for the feedback Robert. I’m glad that you’re pleased with the window board, and sorry you had a bit of difficulty with the delivery. To be totally honest, taking a look at your order it appears that you were one of the first customers that we dispatched too using a new courier, however we also had a couple of teething problems when we started using them.

There were a couple of days whereby the courier had collection issues whilst they setup our account, which may have explained a day or two delay, but it appears that you may have had another unrelated delay (which can occur from time to time with all couriers). I’m hoping that this is a one-off and apologise for the inconvenience. Should you ever need anything else let me know and I would hope that you wouldn’t experience the same courier issue.
