Quick Answer: How Much Does an Interior Designer Cost?
Interior designers in the UK typically charge £50 to £150 per hour, or 10 to 20 percent of the total project budget for full service design and project management. A single room consultation might cost £300 to £800, while a full house project with sourcing and project management can run into several thousand pounds depending on scope and designer experience.
How Interior Designers Charge: Pricing Models Explained
Hourly Rate
Many independent interior designers charge by the hour, typically £50 to £150 depending on experience and location, with London based designers generally at the higher end of that range. This model suits smaller projects such as a single room refresh or a consultation to guide your own DIY work.
Fixed Project Fee
A fixed fee is agreed upfront for a defined scope of work, giving cost certainty for both parties. This works well for clearly defined projects such as a single bedroom or living room, where the designer can accurately estimate the time involved.
Percentage of Project Budget
For larger renovations, many designers charge 10 to 20 percent of the total project budget, covering design, sourcing, and project management through to completion. This model aligns the designer’s fee with the overall scale of the project.
Retail Markup or Commission
Some designers work on a lower or no direct fee basis, instead earning a margin on furniture and materials sourced through trade accounts. This can suit budget conscious clients but it is worth clarifying exactly how sourcing costs compare to buying items yourself.
Interior Design Cost by Project Type
| Project Type | Typical Cost Range | Pricing Model |
|---|---|---|
| Single room consultation | £300 to £800 | Fixed fee |
| Full room design and sourcing | £1,500 to £5,000 | Fixed fee or hourly |
| Whole house renovation design | 10 to 20% of project budget | Percentage |
| Ongoing project management | £50 to £150 per hour | Hourly rate |
Interior Designer Cost Per Room in the UK
Not all rooms cost the same to design. A kitchen or bathroom involves plumbing layouts, tiling plans and technical drawings, so designers charge considerably more for these rooms than for a bedroom refresh. The table below shows typical UK design fees per room in 2026, covering the design fee only, before furniture and materials.
| Room | Design consultation | Full room design service |
|---|---|---|
| Bedroom | £200 to £400 | £800 to £2,500 |
| Living room | £250 to £450 | £1,000 to £3,500 |
| Home office | £200 to £400 | £800 to £2,000 |
| Bathroom | £400 to £700 | £1,500 to £5,000 |
| Kitchen | £400 to £800 | £2,000 to £8,000 |
Kitchens sit at the top of the range because the designer must plan cabinetry layouts, appliance positions, worktop runs, lighting circuits and sometimes structural changes, all coordinated with the kitchen supplier and builder. Bathrooms are close behind for similar reasons: waterproofing zones, drainage falls and sanitaryware placement all need precise drawings. Bedrooms and living rooms are simpler, focusing on layout, colour, lighting and furniture selection, which is why their fees are lower.
Online or e-design services now offer a cheaper per-room route, typically £200 to £500 per room, delivering mood boards, shopping lists and layout plans remotely without site visits. This suits confident homeowners who can manage tradespeople themselves. London fees run roughly 30 to 50 percent above the national figures in the table, reflecting higher business costs in the capital.
What Is Included in an Interior Designer’s Fee?
- Initial consultation and brief gathering
- Concept development, mood boards, and colour schemes
- Furniture, fabric, and material sourcing, often through trade only suppliers
- Space planning and, where relevant, coordination with builders or tradespeople
- Project management through to installation and styling
Not every designer includes all of these as standard, so always confirm exactly what is covered before agreeing a fee, and get the scope in writing.
Factors That Affect Interior Design Cost
Location
Designers based in and around London typically charge more than those in other UK regions, reflecting both higher business costs and client budgets in the capital.
Experience and Reputation
An established designer with a strong portfolio and press coverage will generally command higher fees than someone early in their career, though a newer designer is not necessarily lower quality.
Project Scope
A single room refresh costs considerably less than a full house project involving structural changes, multiple rooms, and coordination with builders and other tradespeople.
Sourcing Requirements
Projects requiring bespoke furniture, extensive trade sourcing, or international shipping will add cost beyond the designer’s base fee.
Do You Need a Full Interior Designer or a Consultation?
Not every project needs full service design. A single paid consultation, where a designer visits, advises on layout, colour, and furniture choices, and provides a written summary, can be enough to guide a confident DIY project at a fraction of the cost of full service design. This suits homeowners updating our own interior design fundamentals with expert input on the specific details.
How to Get the Best Value From an Interior Designer
- Get quotes from at least three designers and compare exactly what is included in each
- Ask to see a full portfolio of completed projects similar in scope to yours
- Clarify whether furniture and material costs are separate from the design fee
- Agree a clear budget ceiling upfront to avoid scope creep on sourcing
- Request a written contract covering fees, timeline, and cancellation terms
Frequently Asked Questions
Is hiring an interior designer worth the cost?
For larger or more complex projects, a designer’s experience in space planning, trade sourcing, and avoiding costly mistakes often justifies the fee. For smaller, simpler updates, a single consultation may offer better value than full service design.
How much does a single room interior design cost?
A single room typically costs £300 to £800 for a consultation only service, or £1,500 to £5,000 for full design, sourcing, and styling depending on the room size and finish level.
Do interior designers charge for the initial meeting?
This varies by designer. Some offer a free initial consultation to discuss scope, while others charge from the first meeting, so it is worth confirming this before booking.
Can an interior designer save you money overall?
Trade discounts on furniture and materials, and avoiding costly design mistakes, can offset some or all of a designer’s fee on larger projects, though this depends heavily on the individual designer and project.
What qualifications should an interior designer have?
There is no legal requirement to hold a specific qualification to work as an interior designer in the UK, so checking a portfolio, client references, and professional body membership such as the BIID is a more reliable indicator of quality than qualifications alone.
Is it cheaper to hire an interior designer for one room?
Yes, starting with a single room is the most affordable way to use a designer. A one room consultation typically costs £200 to £800 depending on the room, letting you test the working relationship before committing to a larger project.
Which room costs the most to have designed?
Kitchens cost the most, with full design services typically running £2,000 to £8,000 in the UK. The technical complexity of cabinetry, appliances, plumbing and electrics requires far more design hours than a bedroom or living room.
What is online interior design and how much does it cost per room?
Online or e-design services deliver mood boards, layout plans and shopping lists remotely, usually costing £200 to £500 per room in the UK. It suits homeowners comfortable managing their own tradespeople, though you miss out on site visits and project management.
Can I hire a designer just for a colour scheme?
Yes. Many designers offer a colour consultation as a standalone service, typically costing £150 to £400. You receive a tailored palette for your rooms with paint references, which is a cost effective way to get professional input on a DIY project.
How do I compare per-room quotes from different designers?
Ask each designer to itemise exactly what their per-room fee includes: number of concepts, revisions, 3D visuals, shopping lists and whether site visits are covered. Two similar headline prices can hide very different levels of service.
Expert Insight
Industry surveys consistently show that unclear scope, rather than the headline fee, is the most common source of client dissatisfaction with interior designers. Agreeing exactly what is and is not included before work begins prevents the majority of billing disputes later in a project.
Final Thoughts
Interior design costs vary widely based on pricing model, project scope, and location, but understanding how designers charge puts you in a much stronger position to compare quotes and choose the right level of service for your budget and project.
Considering hiring a designer? Request an itemised quote breaking down design fees separately from sourcing and material costs, so you can compare like for like across different designers.
