Kitchen Design Service Costs and Options

The kitchen is the most used room in most UK homes, and getting the design right before ordering a single unit is considerably cheaper than correcting a poor layout after installation has begun. Whether you are refitting an existing kitchen or reconfiguring space as part of a larger extension project, the type of designer you need — and what you should expect to pay — varies considerably depending on the scope of work involved.

Key points

• Independent kitchen designers in the UK typically charge £500–£3,000 for a standalone design package; kitchen retailers generally offer a free design service tied to purchasing their own range (Indicative UK costs, last reviewed 2026-05-07).
• KBSA (Kitchen Bathroom Bedroom Specialists Association) membership indicates a designer has agreed to a professional code of practice — a useful indicator when comparing independent practitioners.
• If the project involves structural alterations, removing walls, or a kitchen extension, Building Regulations approval is required and an architectural technologist or architect must produce compliant drawings; this is separate from a kitchen design service.
• Design fees are typically charged as a fixed project package, an hourly rate (£75–£200/hour is typical for independent designers), or absorbed into a supply contract — confirm the charging model before commissioning.
• VAT at 20% applies to design fees and most kitchen supply and installation work for residential properties; budget accordingly.

What does a kitchen design service include?

The scope of a kitchen design service varies significantly between providers. Before comparing costs, confirm exactly what you will receive at each stage of the process.

If your project involves a kitchen extension or structural alterations, you will need an architectural technologist to produce Building Regulations drawings — a separate professional engagement from kitchen design.

Independent kitchen designer

An independent designer not tied to a specific supplier typically charges:

• Hourly rate: £75–£200/hour
• Design package (small kitchen, up to approximately 8 units): £500–£1,200
• Design package (large or complex kitchen): £1,500–£3,000+
• Full-service design, specification, and project management: £2,000–£6,000+

Fees vary with designer experience, London or regional location, project complexity, and whether the brief includes spatial planning connected to an extension or structural change.

Kitchen retailer design service

Most kitchen retailers — from mid-range chains to premium independents — offer design consultations as part of their sales process. The service is:

• Free when the kitchen is purchased from the retailer
• Tied exclusively to the retailer's own product range
• Focused on fitting the kitchen within the existing footprint rather than questioning fundamental layout assumptions

For a straightforward refit within an existing kitchen room, this often represents good value. For complex or open-plan layouts, extensions, or where impartial advice is needed before committing to a supplier, an independent designer will generally provide better outcomes.

Bespoke and premium kitchen designers

For hand-painted, solid timber, or fully bespoke cabinetry, the design service is typically bundled within the supply contract. Design time is absorbed into the overall project cost. Total project costs for bespoke kitchens generally start at £20,000–£30,000+ including supply and installation, with the design fee embedded in the contract structure.

Which type of kitchen designer do you need?

• Choose a kitchen retailer's design service if you are refitting within the existing footprint, your budget is primarily allocated to the product itself, and you are comfortable working within the retailer's range.
• Choose an independent kitchen designer if you want impartial advice, plan to tender the specification to multiple suppliers, or face a complex layout challenge that the space needs to solve.
• Choose an architectural technologist or architect if you are extending the property, removing a wall, or need Building Regulations drawings for any element of the project.
• Choose a design-and-build firm if you want a single point of contact to manage design, structural work, kitchen supply, and installation as one coordinated contract.
• Consult a structural engineer first if the project involves removing a load-bearing wall — a beam design and Building Regulations sign-off will be needed regardless of who manages the rest of the project.

What affects the cost of a kitchen design service?

Designer experience and credentials: A KBSA member with a substantial portfolio typically charges more than a newly established independent. Verifiable credentials, a portfolio of comparable completed projects, and trade references are more reliable indicators of quality than marketing claims alone.

Project complexity: An open-plan kitchen-diner in a Victorian terrace involving a rear extension, RSJ beam installation, and services rerouting is substantially more complex — and more expensive to design — than rearranging units within an existing fitted kitchen room.

Location: Independent designers in London and the South East typically charge 20–40% more than equivalent practitioners in the Midlands, North of England, or Scotland.

Revision rounds: Design fees can increase if the brief expands after instruction. Agree the scope in writing before the design process begins, and clarify how additional changes or revision rounds will be charged.

What to ask before hiring a kitchen designer

• What is included in your fee, and what would be charged as an extra?
• Are your designs supplier-agnostic, or are you tied to a specific range or manufacturer?
• What format will the final drawings and specifications be delivered in — and can I use them to obtain competitive quotes from other suppliers?
• Do you have completed project experience at a similar scale and complexity to mine?
• If the project involves structural work, how do you coordinate with the building contractor and building control?
• Can you provide references from recent completed kitchen projects in the UK?
• Are you a member of KBSA or another recognised professional body?
• What happens if design changes are needed after the installation contractor has started work?
• Is VAT included in the fee you have quoted?
• What are your payment terms and what triggers each stage payment?

When to get professional help

Most kitchen refit projects benefit from at least a design consultation before ordering. Seek professional design and technical input if:

• The project involves removing a wall or changing the structural layout of the property
• You are building a kitchen extension — planning permission or permitted development consent may be needed, and Building Regulations will apply
• Drainage or soil stack positions need to change to accommodate the new layout
• You are unsure whether existing electrics and plumbing can safely support the planned configuration
• You want a design that can be independently tendered to multiple kitchen suppliers for competitive pricing
• The overall project budget is substantial and impartial specification advice would help you compare retailer quotes on an equal footing

Frequently asked questions

Is a paid kitchen design service worth the cost?

For a straightforward refit within an existing room, a retailer's free design service may be entirely sufficient. For complex layouts, open-plan conversions, or where you want impartial advice before committing to a product range, an independent designer typically adds more value than their fee costs — improving the layout, identifying problems before ordering, and helping you compare supplier quotes on a consistent basis.

Do I need planning permission for a new kitchen?

Fitting a new kitchen within your home's existing footprint does not require planning permission. If the project involves extending the property to create additional kitchen space, planning permission or permitted development consent may apply. Rules depend on property location, history, and prior works — check with your local planning authority if you are in any doubt before starting work.

Do I need Building Regulations approval for a kitchen refit?

A like-for-like kitchen refit generally does not require Building Regulations approval. However, removing a load-bearing wall, extending the property, or making significant changes to electrics, drainage, or gas installation will each trigger a Building Regulations requirement. An architectural technologist or your local authority building control team can advise on which elements require compliance sign-off.

How long does the kitchen design process take?

A straightforward consultation and layout plan typically takes 1–3 weeks from first appointment to approved drawings. For complex open-plan projects involving structural changes or bespoke cabinetry, the design and specification phase often takes 4–12 weeks before tendering or placing orders with suppliers.

What is the difference between a kitchen designer and an interior designer?

A kitchen designer specialises in the functional and aesthetic planning of kitchen spaces — unit layouts, appliance placement, worktop specification, and storage. An interior designer has a broader remit covering finishes, furniture, and spatial aesthetics throughout a room. For detailed kitchen specification, a specialist kitchen designer or an architectural technologist is usually the more appropriate choice.
