Kitchen Renovation: What to Plan For Before You Start

A kitchen renovation is unlike most other home improvement projects. The kitchen is used every day, often several times, by most people who live in the house. Losing access to it is genuinely disruptive in a way that losing a spare bedroom or a second bathroom is not. It involves more trades than most rooms: plumber, electrician, plasterer, carpenter and tiler at minimum, often more. And it is a space where the difference between a well-planned result and a poorly planned one is very visible and very daily in its effects.

The people who come through kitchen renovations without losing their minds are, almost always, the ones who did more planning before the work started than seemed necessary at the time. The people who find the process demoralising are usually those who made major decisions on the fly once the room was already stripped out. This piece covers the planning steps that make the difference.

Why planning matters more than design

Kitchen renovation is saturated with design content. Magazines, websites and social media feeds are full of finished kitchens photographed in ideal conditions. This material is useful for developing a sense of what you like, but it creates a misleading impression of what the renovation process involves, because it focuses almost entirely on the result and very little on the process of getting there.

The design decisions, by which I mean the choices about style, colour, materials and finish, are genuinely important. But they are, in most cases, the easier part of the project. The harder and more consequential decisions are the planning ones: how much to spend and on what, what layout works for the space and how you use it, how to manage the household during the work, and how to sequence the trades so that each one can do their work without being blocked by another. These decisions require more thought and have more influence on whether the project goes well than any choice of cabinet door or worktop material.

Setting a realistic budget

Kitchen renovation costs vary enormously. A basic replacement of units and worktops in an existing layout, with no structural work and no changes to the plumbing or electrical routes, can be done for a relatively modest sum. A full renovation that involves moving walls, relocating the sink and hob, replumbing, rewiring and installing high-specification units and materials can cost several times as much. Neither figure is right or wrong; the question is what your kitchen needs and what the result is worth to you.

The starting point is to be honest about what you want to change. If the existing layout works well and the only issue is that the units are tired, a face-lift renovation, replacing the doors, worktops and perhaps the appliances while keeping the carcasses and the basic structure in place, is a very different project in cost and disruption from a full strip-out. Many people who think they need a full renovation would be better served by a face-lift, and many who opt for a face-lift later wish they had addressed the layout at the same time.

Once you have a clearer sense of what the project involves, get quotes from at least three contractors and make sure they are all pricing to the same specification. A vague scope will produce quotes that are hard to compare and that almost always produce variations once the work is under way. A detailed specification, which lists exactly what is included and what the contractor is responsible for, makes comparison straightforward and reduces the scope for surprises.

Build a contingency into the budget. Ten to fifteen per cent is a sensible minimum. In older properties, stripping out a kitchen frequently reveals issues behind the walls: outdated wiring, corroded pipework, damp, or simply a wall that is not where the drawings said it was. None of these are the contractor's fault and most of them need to be addressed before the new kitchen can go in. A contingency that feels unnecessary when you set it often feels exactly right by the time the work is done.

The layout decision, and why it comes first

The layout of a kitchen, by which I mean the positions of the sink, the hob, the fridge, the storage and the work surfaces relative to each other, is the most consequential design decision you will make. It determines how the kitchen works on a daily basis, and it is not something you can easily change once the plumbing and electrical first fix are in.

The kitchen triangle, which relates the positions of the sink, hob and fridge as the three most-used points in a kitchen, is a useful framework even though it has been around long enough to attract some dismissal. The principle behind it, that the distance and path between the things you use most often should be short and unobstructed, remains sound. A kitchen where you have to cross the room to move between the hob and the sink adds friction to every meal you cook.

Think about the specific ways your household uses the kitchen. If two people cook regularly, is there enough worktop space for both to work simultaneously without getting in each other's way? If the kitchen is also used for homework or working from home, is there a surface that can be kept clear of cooking for that purpose? If children reach for snacks independently, can the relevant storage be accessed without going through the primary cooking zone? These are questions that a kitchen designer will ask, and they are worth thinking through before any design conversation begins.

If you are considering moving the sink or the hob, factor the plumbing and extraction implications into the budget before you commit to the decision. Moving a sink to the other side of the room is straightforward in principle and sometimes expensive in practice, depending on the floor construction and the existing drain runs. Moving a hob that requires ducted extraction requires new duct routes to be created. Neither is insurmountable, but both add to the cost and the complexity, and they need to be included in the quote rather than discovered afterwards.

Living without a kitchen during the work

This is the part of kitchen renovation planning that receives less attention than it deserves, and it is the part that has the most immediate effect on whether the process is tolerable or miserable.

A typical kitchen renovation, from strip-out to completion, takes between three and eight weeks for a standard domestic kitchen, depending on the complexity of the work and the number of trades involved. During that time, you will have no cooking facilities in the kitchen. This is a significant constraint that requires a plan.

Set up a temporary kitchen in another room before the work begins. A microwave, a kettle, a toaster and a small portable induction hob, combined with a full-sized fridge, gives you the ability to prepare basic meals without relying entirely on takeaways and restaurants. This is better for the budget, better for wellbeing, and better for the contractors, who will be working in a house that does not feel entirely abandoned.

Think about washing up. If your only sink is in the kitchen, you will need to use the bathroom for washing up during the renovation. This is manageable for a few weeks but worth preparing for. Silicone mats to protect the bath, a drying rack that fits the bathroom context, and a clear plan for how this works day to day will make the constraint much less stressful.

Choosing materials that will last

The worktop, the flooring and the sink are the elements of a kitchen that receive the most daily punishment, and they are the ones where the difference between a material that performs well over time and one that does not is most visible.

Solid stone worktops, whether natural stone such as granite or engineered stone composite, are durable and can be repaired if they are scratched or chipped. They require some maintenance: natural stone needs periodic sealing, and engineered stone can stain if spills are left too long. Both are significantly more expensive than laminate options but last indefinitely if properly cared for.

Laminate worktops have improved considerably and offer good value and a wide range of appearances. Their weakness is the edges and joints, which can swell and delaminate if they are regularly exposed to water. Good installation and prompt attention to any damage makes a significant difference to how long they hold up.

Kitchen flooring needs to be durable, water-resistant and easy to clean. Porcelain tile is the most practical choice for most kitchens: it is hard-wearing, waterproof, and easy to maintain. Large format tiles with minimal grout joints are easier to clean than smaller tiles with more grout. The choice of tile finish affects slip resistance when wet, which is worth considering in a space where spills are frequent.

The order of trades, and why it matters

The sequence in which different trades carry out their work has a direct effect on how smoothly the renovation progresses. Trades that are scheduled in the wrong order have to undo or work around each other's work, which adds time and cost and creates friction between contractors who would otherwise work efficiently.

The correct general sequence for a kitchen renovation is: structural work if any, then first fix plumbing and electrical, then plastering, then second fix plumbing and electrical, then floor preparation and laying, then units, then worktops, then tiling, then appliances and finishing. Each stage has to be substantially complete before the next can proceed, and the dependencies need to be clear to all parties before work begins.

The worktop measurement and templating stage is one that regularly causes delays if it is not planned carefully. Templating, the process of precisely measuring the worktop opening to allow it to be cut accurately at the workshop, cannot be done until the units are installed and levelled. The fabrication of the worktop then takes typically one to two weeks. During that time, the kitchen is substantially complete except for the worktops and anything that depends on them, including the splash back tiling behind the hob and sink. Sequencing around this delay, and making sure the contractor and the other trades are aware of it, prevents the frustration of a kitchen that is nearly finished for two weeks longer than it needs to be.
