Introduction
Kitchen renovation costs vary because two projects of the same room size can involve very different work. One kitchen may keep its existing layout and replace finishes. Another may move plumbing, add new electrical circuits, change flooring and install fully bespoke cabinetry.
The most useful way to understand a kitchen budget is therefore to break the project into the decisions that actually drive cost.
This article deliberately focuses on those cost drivers rather than publishing generic price ranges that can become misleading as material, labour and specification choices change.
1. The existing kitchen condition
Before the new kitchen is priced, consider what has to be removed or repaired.
Possible work includes:
- stripping cabinetry and appliances;
- removing wall/floor finishes;
- making good damaged walls;
- addressing moisture or plumbing issues;
- levelling floors;
- replacing old services before new finishes are installed.
A kitchen that is ready for a straightforward replacement is a different project from one requiring extensive preparation.
2. Whether the layout changes
Keeping sinks, appliances and major services in approximately the same locations can reduce disruption. Moving them may improve the kitchen significantly, but can introduce additional plumbing, drainage, electrical and building work.
Layout decisions should be driven by how the room needs to function, not only by keeping cost low. The important thing is to understand the consequences before the specification is fixed.
3. Cabinetry and storage
Cabinetry is one of the largest variables in a kitchen renovation.
Budget is influenced by:
- number and size of units;
- bespoke versus standard dimensions;
- door/front material;
- internal storage systems;
- tall units and pantry storage;
- handles or handleless details;
- drawer hardware and mechanisms;
- finishing around awkward walls or corners.
Good planning often creates more value through improved storage and circulation than through decorative upgrades alone.
4. Worktops and splashbacks
Worktop cost depends on the selected material, thickness, fabrication, edge details, cut-outs and overall length.
Also consider:
- upstands/splashbacks;
- waterfall ends or feature panels;
- sink cut-outs;
- hob cut-outs;
- joints and access requirements.
These details affect fabrication and installation, so they should be decided before the final quotation is treated as fixed.
5. Appliances
Appliance specification can range widely. Beyond purchase price, appliances may also influence:
- cabinet dimensions;
- electrical demand;
- water/drain connections;
- ventilation/extraction;
- worktop cut-outs;
- final installation.
Choose key appliances early enough for the kitchen design to accommodate them accurately.
6. Plumbing changes
Moving a sink, dishwasher or other water-connected appliance can require changes behind walls or below floors.
The condition of existing plumbing matters too. A cosmetic renovation may not remain cosmetic if old services are discovered to be unsuitable for the new installation.
7. Electrical upgrades
Modern kitchens can require significant electrical capacity for ovens, hobs, refrigeration, dishwashers, small appliances, lighting and sockets.
The cost depends on the existing installation and the new appliance/layout plan. Electrical work should be confirmed before cabinetry and finished surfaces close access to the services.
Any regulated electrical work must be delivered in line with applicable professional/licensing requirements; Rodi's exact standalone electrical service model remains a business-confirmation item.
8. Flooring, ceilings and lighting
A kitchen project may also include:
- new floor finishes;
- wall preparation/painting;
- ceiling repairs;
- task lighting;
- feature lighting;
- new switches/sockets;
- changes to adjacent dining/living areas.
The broader the room integration, the more important it is to price the full scope rather than only the cabinets.
9. Specification versus value
The highest-cost material is not automatically the best choice for every property. A good kitchen specification balances:
- durability;
- appearance;
- maintenance;
- storage/function;
- budget;
- how long the owner expects to use the property.
Spend where it changes daily use or long-term durability, not simply where a finish looks more expensive.
How to get a useful quotation
Provide the contractor with:
- property/location;
- current kitchen dimensions or plans;
- whether the layout changes;
- required appliances;
- cabinetry/storage expectations;
- preferred material level;
- any known plumbing/electrical issues;
- whether floors/walls/ceilings are included.
A quotation can only be as clear as the scope it is based on.
FAQ
What is the biggest kitchen renovation cost driver?
There is no single answer. Cabinetry, worktops, appliances and service/layout changes are usually among the most significant variables.
Is keeping the existing layout cheaper?
It can reduce plumbing/electrical/building changes, but the best layout should still meet the practical needs of the household.
Why not publish a fixed cost per square metre?
Kitchen specification varies too much for a single area-based figure to describe cabinetry, appliances, worktops and service changes accurately.
