Flat-Pack vs Rigid Kitchen Units: Which Is Better?
Flat-pack or rigid kitchen units? Compare strength, cost, fitting time and access up a Glasgow stair, plus which brands sell which. Assembly £25 a cabinet.
The right choice depends on how you want to buy and how much of the job you want to manage. IKEA kitchens are flat-pack and bought directly, Howdens kitchens are rigid and sold only through tradespeople, and DIY Kitchens are rigid and ordered online. We fit all three across Glasgow from £795, and only IKEA adds a flat-pack assembly charge, of £25 a cabinet.

IKEA, Howdens and DIY Kitchens differ most in how you buy them and how they arrive, not in whether they can make a good kitchen. All three can look excellent when they're fitted properly. This table puts the practical differences side by side.

|---|---|---|---|
| How you buy it | Yourself, in store or online | Through a tradesperson with a trade account | Yourself, online |
| How it arrives | Flat-pack | Rigid, ready-built cabinets | Rigid, ready-built cabinets |

Prices are our November 2026 fitting prices with no VAT added. The cost of the kitchen itself depends on the range, the size and any sale, so compare full quotes from each supplier.
An IKEA kitchen gives you a lot of choice and control at a sharp price, in exchange for more work before and during the fit.
A Howdens kitchen suits homeowners who'd rather choose a style and hand over the ordering, because Howdens only sells through tradespeople.
DIY Kitchens suits confident planners who want ready-built cabinets at an online price and are happy to organise their own fitter.
Once fitting is included, ready-built kitchens often close the gap on flat-pack ones, because there's no assembly to pay for. For a typical 12-unit kitchen fitted by us:
| 12-unit kitchen | Fitting | Assembly | Fitting total | Time on site |
|---|---|---|---|---|
| IKEA (flat-pack) | £1,250 to £2,200 | £300 (12 × £25) | £1,550 to £2,500 | 4 to 7 days |
| DIY Kitchens (rigid) | £1,250 to £2,200 | None | £1,250 to £2,200 | 3 to 5 days |
| Howdens bought through another trade (rigid) | £1,250 to £2,200 | None | £1,250 to £2,200 | 3 to 5 days |
| Howdens supplied and fitted by us | Kitchen and fitting in one quote | None | Most supply-and-fit kitchens £6,500 to £11,000 before appliances | 4 to 6 days |
To compare fairly, add the price of the kitchen from each supplier to the fitting total, and remember removal of the old kitchen (from £195) and any gas or electrical work. Our Glasgow kitchen fitting price guide has worked examples for each.
All three can work in a tenement, but they suit different buildings. Flat-pack has the edge on a narrow, winding stair, while rigid units save time once they're inside.
Our tenement kitchen fitting page explains how we handle old walls, sloping floors and narrow stairs.
Choose the supplier that matches how you like to work. These rules of thumb cover most Glasgow homeowners:

IKEA units are often cheaper to buy, but compare the total, not just the cabinets. IKEA kitchens need assembling, which adds £25 a cabinet with us, while Howdens units arrive built. Howdens pricing also depends on the tradesperson who orders it. Ask for a full quote for each, including doors, worktops, panels and fitting, then compare like for like. Ask us to price fitting for both before you decide.
Both can make a kitchen that lasts when it's fitted properly. Howdens cabinets arrive rigid, built in the factory, while IKEA cabinets are assembled on site, so assembly quality matters more with IKEA. IKEA offers a 25-year guarantee on METOD cabinets, and Which? reports a 25-year guarantee on Howdens cabinets. The fitting makes as much difference as the brand. Both look excellent when they're fitted square, level and properly scribed.
No. Howdens sells only to trade customers, so a homeowner buys a Howdens kitchen through a tradesperson with a trade account, such as a kitchen fitter or joiner. We can order your Howdens kitchen through the trade and fit it, and your quote shows the kitchen and the fitting as separate lines so you can see where the money goes.
No. DIY Kitchens manufactures and delivers the units ready-built, but installation is up to you and your own fitter. That's why it pays to book a fitter before you order: they can check your plan, match the fitting date to your delivery slot and confirm that tall and corner units will fit through your doors and up your stair. We fit DIY Kitchens units across Glasgow, with no assembly charge because they arrive built.
Ready-built kitchens, such as Howdens and DIY Kitchens, are quickest, because fitting starts on the first day. A typical 12-unit rigid kitchen takes us 3 to 5 days. The same size of IKEA kitchen takes 4 to 7 days, because every flat-pack cabinet has to be built before it's fitted. Removing the old kitchen adds half a day to a day.
Only for the assembly. Fitting prices are the same for every brand: from £795 for up to 8 units and £1,250 to £2,200 for 9 to 15 units. IKEA kitchens arrive flat-packed, so we add £25 a cabinet to build them. A typical 12-cabinet IKEA kitchen costs £1,550 to £2,500 to fit with us, including assembly. For a 12-unit IKEA kitchen, that's £300 on top of the fitting price.
Yes. Several companies make doors and panels designed to fit IKEA cabinets, and many people use them to get a more individual look. You can also mix worktops and sinks from different suppliers. Tell us what you're combining at the plan stage, so we can check the sizes, hinges and fixings before anything is ordered. Tell us your plan at the survey and we'll check the sizes match before you order.
It depends on the stair and the room. IKEA's flat-pack boxes go up any stair, and its adjustable legs help on sloping floors. Rigid units from Howdens or DIY Kitchens save fitting time, but tall and corner units must fit through the close, round the landings and into the flat, so we measure the access at the survey. We check your close and stair as part of the free survey.
