Want is the most cost effective way of getting new kitchen

Buying a kitchen is always much cheaper as they are able to mass produce.

It will be more cheap to buy a kitchen from wicks even the drowning and plan is for free and the leabor it will be lower the to build a new one from wood or mdf

Depending on your personal requirements. I have found that if you want generic sizes for everything then it is usually much cheaper and much faster to go with buying a kitchen, However bespoke kitchens can be better value for money in terms of usable space and personal flare. you can usually get a bespoke kitchen made cheaply if you contact the manufacturers directly and source the kitchen yourself or get a trustworthy tradesman to do the deal for you at cost, this is unlikely but can be achieved.

Getting a trade to buy you one, as they get much better discounts.
