How Long Does a Bespoke Kitchen Renovation Actually Take?
Right after "how much will it cost," the question we hear most often is "how long will it take." It's a fair thing to want a clear answer to, since a kitchen renovation affects daily life more than almost any other home project, you can't easily avoid using your kitchen the way you might a spare bedroom being redecorated. Here's a realistic breakdown of the full timeline, and what tends to make projects run longer or shorter than expected.
The two phases that matter
It helps to separate a kitchen renovation into two distinct phases, since they behave very differently:
Planning and ordering. This covers your initial consultation, design development, finalising the specification, and placing orders for cabinetry, worktops and appliances. For a genuinely bespoke kitchen, this phase often takes longer than people expect, not because decisions are slow, but because custom cabinetry, natural stone worktops and specific appliance models all carry their own manufacturing and delivery lead times, often running to several weeks each.
On-site construction and installation. This is the phase most people picture when they think of "the renovation", demolition, any structural or first-fix electrical and plumbing work, cabinet installation, worktop templating and fitting, and final appliance connection and snagging.
Realistic timeframes
As a general guide, a straightforward kitchen replacement, keeping the existing layout, with no structural changes and no extension involved, can often move through on-site installation in a matter of weeks once materials arrive. A more involved project, particularly one including structural changes, an extension, or significant electrical and plumbing rework, realistically needs several months when planning, ordering and construction are all accounted for together, not just the visible on-site work.
The single biggest factor isn't the size of the kitchen, it's how much of the surrounding structure, walls, electrics, plumbing, is changing alongside it. A kitchen that's simply being replaced within its existing footprint moves markedly faster than one involving an extension or a knocked-through wall.
What actually causes projects to run longer than expected
A few specific things consistently extend timelines, more than the headline scope of the project itself:
Long-lead items. Bespoke cabinetry, natural stone worktops, and certain specialist appliances often carry the longest lead times in the entire project, and these need to be ordered well before on-site work begins, not scheduled around it as an afterthought.
Structural surprises. Opening up walls or removing existing units sometimes reveals issues that weren't visible beforehand, ageing wiring, damp, or structural elements that need addressing before work can continue. This is more common in older London properties than newer builds.
Change orders mid-project. Adjusting layout, materials, or specification after work has already started is one of the most common causes of delay, since it can require re-ordering materials or resequencing trades that had already been scheduled.
Inspection and sign-off timing. Where building regulations sign-off is required, particularly for structural or significant electrical work, inspection scheduling can add time that's outside your project team's direct control.
Can you still use your kitchen during the work?
For a straightforward like-for-like replacement, some homeowners manage a basic temporary setup, a kettle, microwave and a folding table in another room, for the more disruptive stretch of the project. For anything involving significant structural work, it's realistic to expect the kitchen to be fully out of action for a period, and worth planning a temporary cooking arrangement elsewhere in the house in advance, rather than discovering the need for one partway through.
Why getting the timeline right matters as much as the design
A realistic timeline, agreed honestly at the outset rather than optimistically rounded down, is one of the biggest factors in a renovation feeling smooth rather than stressful. This is exactly why we build lead times for cabinetry, worktops and appliances into your project schedule from the earliest planning stage, so the timeline you're given reflects what's genuinely achievable for your specific specification, not a generic estimate.
If you'd like a realistic timeline for your own project, book a design consultation with our team, and we'll talk you through what to expect from first meeting to final handover.
