I made a couple of trips up to the showroom (I was going up North anyway and so it was easy for me to swing by) and they were hugely helpful. I managed to find out the difference between Linwood, Milton, Norton ranges. Basically there are two "shaker" styles - one with ridges in the door and one without (I think that's the difference between Linwood and Norton)...and for each style there are two options - full wood door and foil wrapped mdf. When we priced it up the full wood (which is what Linwood is - Malton is the equivalent but foil wrapped mdf) option was only about £500-£600 more so we opted for that. On a small scale just looking at sample doors you can't notice the difference between full wood and foil wrapped mdf. However on a larger scale, the wooden doors are much more substantial and have nicer markings / are more natural in my view.
We opted for the Linwood range (graphite). I quite liked the fact we could have the carcasses the same colour.
Ordering process was pretty smooth - you can call them and speak to them or go to the showroom and work through your plan with someone. The major downside is that once the order goes through for manufacture there are no changes or returns (unless faulty or damaged). Therefore if you make a mistake it's on you / at your cost!
We ordered before Christmas as we wanted an install early January. However they then launched a 10% off sale on Boxing Day - we called them and they agreed to refund us 10% to match the sale offer which was a nice bonus and something they (strictly speaking) didn't need to do. 🙂
