Its interesting to see alanl’s opinion as a fitter, he wants to save time, so likes the howdens product as the carcasses come assembled.
TBH I always take the fitter/chippys opinion with a pinch of salt as their motivation is that which makes their life better, which is not neccesarily coincident with the user/owner.
As a student rental property owner I’ve had two ikea kitchens and a howdens one. Students are excellent barometers of quality when it comes to house fixtures and fittings..
As rental manager (no longer) I looked after 35 properties all with ikea kitchens, they have proven to be very resilient.
The howdens kitchen was my chippys idea, as he was keen on not having to build ikea flat pack and had just been given a howdens account. It has proven to be a very poor choice. After 3 years is falling to bits, with one carcass collapsing, two doors falling off. The real difference is in the doors, the ikea ones are solid wood, the howdens are essentially chipboard with a pressed on cover, they have warped, the one on the sink has been water damaged from drips down the front where the washer upper has been a bit sloppy, it penetrated the chipboard and its all swollen. Utter rubbish. Would never ever go to howdens again.
My ikea kitchens are 8 and 9 years old and they are still going strong. I’ve just priced up another one at ikea – the units do have backs to them?
It should be noted that the chippy glued and screwed (called Beacon Heathing, glue and a screw is what you get on Beacon Heath) the ikea cabinets together which has made them utterly solid.
