If you’re planning a new kitchen, one of the first choices you’ll face is flat-pack versus fitted. The terms get used loosely, and the difference isn’t always what people expect — it’s really about how the units arrive and who builds them, not the quality of the finished kitchen. This guide explains what each means, how they compare on cost, quality and flexibility, and which suits your project — so you can choose with your eyes open.
1. What’s the difference?
Flat-pack units are delivered as flat boxes of pre-cut, pre-drilled panels that you (or a fitter) assemble on site. Rigid units arrive already built. “Fitted” simply means a kitchen that’s installed to fit your room — and you can create a fitted kitchen from flat-pack units just as easily as rigid ones. The finished result looks the same; the difference is in the delivery and build.
2. Cost compared
Flat-pack is almost always the more affordable route, for two reasons: flat boxes are cheaper to ship and store than bulky built cabinets, and you’re not paying a showroom to assemble them. Buying the units yourself and building them (or paying a local fitter) typically costs far less than a fully-fitted showroom kitchen for a comparable spec.
| Flat-pack | Fully-fitted (showroom) | |
|---|---|---|
| Unit cost | Lower | Higher |
| Delivery | Cheaper (flat boxes) | More expensive |
| Assembly | DIY or your own fitter | Included (at a premium) |
| Flexibility | Buy exactly what you need | Often sold as packages |
3. Flexibility & choice
Because flat-pack units are sold individually, you order exactly the cabinets your layout needs rather than a fixed package — a real advantage in awkward or unusual rooms. You can mix base, wall, tall and sink units freely, and phase your purchase over time if you’d like to spread the cost.
4. Assembly & installation
Flat-pack units are designed to go together with basic tools, and the panels are pre-drilled to make it straightforward. If you’re handy, you can build them yourself; if not, any competent fitter or handyperson can assemble and install them quickly — usually still for less than a fully-fitted quote. Rigid units skip the assembly step but cost more and are harder to carry through the house.
5. Quality & durability
There’s a myth that flat-pack means flimsy — it doesn’t. The quality of a kitchen comes from the materials and the build, not whether it arrived in a box. A well-made flat-pack unit, properly assembled and fixed to the wall, is every bit as sturdy and long-lasting as a rigid one.
6. Delivery
Flat-pack’s compact boxes are far easier to deliver and carry through your home — a genuine benefit if you have narrow hallways, stairs or tight access. We deliver kitchen units across England and Wales, with delivery costs and timescales shown at checkout.
7. Which is right for you?
- Choose flat-pack if you want the best value, the flexibility to buy exactly what you need, and easier delivery — and you’re happy to assemble the units or use a fitter.
- Choose rigid if you’d rather skip assembly entirely and don’t mind paying more for the convenience.
8. How our flat-pack kitchens work
Our kitchen units are supplied flat-pack. You buy individual cabinets in the sizes you need, each base unit comes with a shelf and shelf pins as standard, and the panels are pre-drilled ready to assemble. It’s the most affordable, flexible way to build a fitted kitchen. See our kitchen units buying guide to plan the whole project.

Whichever route you choose, a well-planned kitchen is a brilliant investment in your home. When you’re ready, browse the kitchens range and start building your list.
Frequently asked questions
Are flat-pack kitchens cheaper than fitted?
Yes, usually. Flat-pack boxes are cheaper to ship and store, and you’re not paying a showroom to assemble the units. Buying the cabinets yourself and building them — or using a local fitter — typically costs far less than a fully-fitted showroom kitchen of a similar spec.
Are flat-pack kitchens good quality?
They can be excellent. Quality comes from the materials and how well the units are built and fixed, not from whether they arrived flat-packed. A well-made, properly assembled flat-pack unit is just as sturdy and durable as a rigid one.
Can I install a flat-pack kitchen myself?
Yes. Flat-pack units are designed to assemble with basic tools and come pre-drilled. If you’re handy you can do it yourself; if not, any competent fitter or handyperson can build and install them, usually still for less than a fully-fitted quote.
What’s the difference between flat-pack and rigid units?
Flat-pack units arrive as flat boxes of pre-cut panels you assemble on site; rigid units arrive already built. The finished kitchen looks the same — flat-pack is cheaper and easier to deliver, rigid saves you the assembly step but costs more.
Does “fitted” mean the same as “rigid”?
No. “Fitted” just means a kitchen installed to fit your room, and you can build a fitted kitchen from flat-pack or rigid units. “Rigid” specifically refers to units that arrive pre-assembled.
Do flat-pack units come with everything needed to build them?
Our base cabinets are supplied with a shelf and shelf pins as standard, and the panels are pre-drilled for assembly. Check each product page for full details of what’s included.
Is flat-pack easier to get into my home?
Yes — the compact flat boxes are much easier to carry through narrow hallways, up stairs and around tight corners than bulky pre-built cabinets, which is a real advantage in many homes.
Can I buy just a few units rather than a whole kitchen?
Yes. Because units are sold individually, you can order exactly what you need — whether that’s a full kitchen or a single replacement cabinet — and even phase your purchase to spread the cost.
