What Happens If Kitchen Units Don't Fit?

Why Units Sometimes Don't Fit

The most common reason is a discrepancy between the kitchen designer's plan dimensions and the actual room dimensions. Walls that are not plumb, floors that are not level, or alcoves that are smaller than specified on the plan all cause units to not fit as designed.

What the Fitter Can Do

• Use filler panels (infill strips) to close gaps between units and walls
• Order a modified-width unit from the retailer if a significant gap exists
• Adjust the layout within the run to redistribute space
• In some cases, trim a carcass (though this is not always possible depending on material)

Why Surveys Prevent This

A professional pre-installation survey cross-checks every dimension on the plan against the actual room. Problems are identified before the kitchen is delivered, allowing corrections to the order before installation begins — not during it.

A Typical Resolution Timeline

• On the day: Fitter identifies the mismatch and pauses that section of the installation
• Within 24 hours: Retailer contacted to confirm whether a replacement or modified unit is possible
• 3 days–4 weeks: Replacement unit lead time, depending on retailer and stock
• On arrival: Fitter returns to complete the affected section

Minimising Disruption While You Wait

A good fitter will complete every other part of the installation that isn't affected by the missing or wrong-size unit, so you're not left with a completely unusable kitchen while waiting for a replacement — only the specific section in question is left open.

Can the Room Just Be Redesigned Instead of Waiting?

Sometimes, yes — if a filler panel or a slightly different unit combination achieves an acceptable result without ordering a replacement, this is often faster and can be agreed with your fitter and retailer on the spot.
