A fitted kitchen can look straightforward once the doors are closed and the worktops are in place. Behind that finished room, however, there are measurements, services, trades and decisions that all need to line up. This guide to fitted kitchen installation explains what should happen before, during and after fitting, so you can plan with confidence and avoid the costly surprises that tend to delay a project.
A well-managed installation is not simply about assembling cabinets. It is about making the room work properly for your household, from safe appliance connections and practical storage to a finish that still looks right years from now.
Start with a proper survey, not just a rough plan
The installation process should begin long before delivery day. A detailed home survey confirms the true dimensions of the room, including wall lengths, ceiling height, window positions, pipework, radiators, consumer units and any uneven floors or walls.
This matters particularly in older homes, where a wall that appears square can be noticeably out once cabinets are fitted alongside it. A good designer allows for fillers, end panels and practical clearances rather than forcing standard units into a space they do not suit.
The survey is also the point to discuss how you use the kitchen. A family that cooks most evenings may prioritise generous preparation space and a larger pantry unit. Someone downsizing may prefer easy-access drawers, integrated appliances and fewer hard-to-reach cupboards. There is no single ideal layout – it depends on the room and the people using it.
Confirm the layout before anything is ordered
Before manufacture or ordering begins, make sure you are happy with the proposed plan. Check the opening direction of doors, the position of handles, appliance clearances and whether drawers can open without clashing with another unit or doorway.
It is worth standing in the planned positions of the sink, hob and fridge and considering everyday movement. The classic working triangle can be useful, but it should not override common sense. For example, placing the dishwasher close to the sink often makes more difference to daily convenience than following a textbook layout.
This is also the time to select your worktop, splashback, sink, tap, flooring and appliances. These choices affect measurements and installation order. A thick worktop, a Belfast sink or a tall American-style fridge can all require different allowances from a standard plan.
Preparing the room for fitted kitchen installation
Once the final design is agreed, the existing kitchen usually needs to be removed and the room prepared. Depending on the project, this may involve taking out old units, lifting flooring, removing tiles, altering plumbing, upgrading electrics or replastering damaged walls.
Do not assume every surface needs to be perfect before fitting begins. Base and wall cabinets can accommodate minor inconsistencies, but serious damp, crumbling plaster, unsafe wiring or a badly uneven floor should be dealt with first. Covering a problem with new cabinetry only makes future repairs more difficult.
Plan services around the new kitchen, not the old one
Many homeowners are surprised by how often electrical and plumbing work is needed. New appliance positions may require additional sockets, dedicated circuits or altered pipework. Extraction for a cooker hood needs particular attention, especially if you want it vented outside rather than recirculating air back into the room.
An electrician should confirm that the existing installation can safely support the new load, particularly where induction hobs, built-in ovens and multiple integrated appliances are being added. Gas work must be carried out by a suitably qualified Gas Safe registered engineer.
If walls are being opened up, new flooring is planned or a radiator is moving, coordinate these jobs early. The fewer last-minute changes made once cabinets have arrived, the smoother the fitting programme will be.
What happens during the fitting stage
A professional fitted kitchen installation follows a logical sequence, although the exact order can vary according to the room, the selected products and the trades required.
First, fitters establish a level starting point. Floors and walls are rarely completely straight, so cabinets are carefully adjusted to create level worktop lines and aligned door gaps. This precision is one reason rigid, factory-built cabinets are often preferred for a long-term kitchen – they provide a solid base for accurate fitting.
Base units are normally installed before worktops, with tall housings and wall units positioned according to the agreed design. Fitters then add panels, cornices, plinths and internal fittings. Doors and drawer fronts are adjusted near the end, when the full arrangement can be aligned properly.
Worktops are usually fitted after the cabinets. Laminate worktops may be templated and installed quickly, while stone, quartz and some solid-surface worktops often require a separate template appointment once the base units are in place. That can add time to the schedule, but it allows the fabricator to measure the finished cabinetry accurately.
Appliances are generally installed after the main units and worktop are ready. Connections for gas, water and electrics should be completed by the right qualified tradespeople, with appliances tested before handover.
Expect a programme, but allow for sensible flexibility
A straightforward kitchen replacement may be fitted in days once the room is ready. A larger renovation involving replastering, electrical alterations, flooring, building work or specialist worktops can take several weeks from strip-out to final sign-off.
The key is to distinguish between a well-planned programme and an unrealistic promise. Some stages have to happen in sequence. For instance, you cannot accurately template a quartz worktop before cabinets are fitted, and it is unwise to fit final flooring before work that may damage it unless the flooring specification and installation order have been agreed.
Ask who is managing each stage and what happens if an unexpected issue is found. A fully project-managed service gives you one main point of contact rather than leaving you to chase a joiner, electrician, plumber, plasterer and worktop supplier separately.
Check the details before sign-off
The final visit is your opportunity to inspect the room carefully. Open every door and drawer, check that handles are secure, and make sure cabinet fronts sit evenly. Look over the worktop joints, seals around sinks and splashbacks, and the finish of panels against walls and ceilings.
Test lighting, taps, extraction and appliances where possible. You should also receive the relevant product information, care guidance and guarantees. Kitchen units, hinges, worktops and appliances may each have different warranty terms, so keep these documents together.
Small adjustments after fitting are normal. Doors can settle slightly and may need a final tweak, particularly after a room has warmed up or been used for a few weeks. What matters is that any snagging is recorded clearly and dealt with properly.
Protect the finish from the first week
A new kitchen benefits from simple care rather than harsh treatment. Wipe spills promptly, avoid leaving standing water around sink cut-outs, use chopping boards and follow the manufacturer guidance for your particular worktop. Steam from kettles and air fryers should not be directed repeatedly at cabinet edges or wall units.
It is equally sensible to keep spare tiles, flooring planks or paint from the project. If damage occurs later, having the correct batch and colour can save considerable trouble.
Choosing an installer you can rely on
Price matters, but fitting is not the place to compare quotes line by line without checking what is included. One estimate may cover cabinet installation only, while another includes removal, plumbing, electrics, plastering, worktop fitting, appliance installation and waste removal.
Ask whether the kitchen is made to suit the room, whether units arrive rigid or flat-packed, who carries out the fitting, and how any issues will be handled after completion. Local experience is valuable too. A company familiar with homes across Glasgow and Central Scotland is more likely to understand the practical quirks of local property types and coordinate trusted trades efficiently.
Discount Kitchens & Bathrooms takes this joined-up approach, combining a free no-obligation design consultation with Scottish-made cabinetry and approved installation teams. For homeowners, that means less time spent managing separate contractors and more certainty about who is responsible for the finished result.
The best time to raise a concern is before fitting starts, not when the worktop is already cut. Take your time with the design, ask direct questions about the programme and keep a written record of agreed choices. A fitted kitchen is a major investment, and careful planning gives it the best possible start.
