One of the most common questions we receive at Kachi Interiors is a simple one: how much does interior design actually cost in London? It's a fair question — and one that most designers are frustratingly vague about. This guide breaks it down clearly, so you can plan your project with confidence.
The Short Answer
Interior design costs in London vary significantly depending on the level of service, the size of your project and the experience of the designer. As a broad guide for 2026:
Online or remote design packages: from £395 per room
Full-service room design: £800 — £3,000+ per room
Full residential project (London): £5,000 — £20,000+
Hourly rates: £75 — £450 per hour depending on experience
The wide range exists because interior design is not one thing. A mood board and shopping list is a very different service to a full concept, technical drawings, bespoke joinery specifications and project coordination.
The Three Main Pricing Structures
1. Fixed package pricing
The most transparent option. You pay a set fee for a defined scope of work — typically a mood board, furniture layout, material selections and a shopping list, with additional elements available in higher-tier packages.
This is how Kachi Interiors packages are structured — starting from £395 per room, with clear deliverables at every level. You know exactly what you're getting and what it costs before you commit.
2. Hourly rate
London designers typically charge between £180 and £450 per hour, with more experienced designers or those working on complex bespoke projects sitting at the higher end. Hourly billing can work for small, clearly defined tasks — but for larger projects it can be difficult to predict the final cost.
3. Percentage of project value
Some designers charge a percentage of the overall project value — typically between 10% and 25% — which reflects the full scope of their involvement.
What Affects Interior Design Cost?
Location within London
Properties in prime central London — Mayfair, Chelsea, Notting Hill, Hyde Park Gardens — often involve higher logistics costs, access challenges and higher contractor rates, which can push design fees up accordingly.
Scope of service
A single room refresh with a mood board and shopping list sits at one end of the scale. A full renovation with bespoke joinery drawings, technical elevations, material specifications and contractor coordination sits at the other. The more involved your designer is, the higher the fee — and rightly so.
Bespoke elements
Projects involving bespoke joinery, custom furniture and handcrafted detailing naturally sit at the higher end — they require more design time, more detailed drawings and closer coordination with specialist contractors.
Online vs in-person
Remote or online interior design services typically cost less than in-person, as they remove travel time and site visit costs from the equation — without compromising on design quality.
All Kachi Interiors packages are delivered remotely, making them accessible to clients in London and worldwide.
A Realistic Budget Guide by Room
Room | Online Package | Full Service |
Bedroom | From £395 | £800 — £2,500 |
Living room | From £395 | £1,000 — £3,500 |
Bathroom | From £795 | £1,500 — £5,000 |
Kitchen | From £795 | £2,000 — £8,000+ |
Full home (London) | POA | £5,000 — £20,000+ |
These figures cover design fees only and do not include furniture, materials, finishes or contractor costs.
What Should Be Included at Each Price Point?
From £395 per room — Styling & Mood
At this level you should expect a mood board, scaled furniture layout, colour and material direction and a curated shopping list. Ideal for clients who have a clear idea of their style and want professional direction rather than full design development.
From £795 per room — Room Design
This should include everything above plus 2D and 3D visualisations, refined furniture and lighting selections, and design support through the process. You see the room before you commit to buying anything — which is where the real value lies.
From £1,195 per room — Full Signature Design
At this level expect full technical drawings, bespoke joinery design, room elevations, material and finish specifications, and enhanced support during the execution phase. This is appropriate for renovations and rooms requiring custom-built elements.
Is It Worth It?
A well-considered interior design can meaningfully increase a home's resale value — particularly when improvements focus on layout, flow and durable material choices rather than purely decorative changes.
The question is less whether interior design is worth it and more whether you're getting the right level of service for your project. A homeowner refreshing a bedroom doesn't need the same service as someone undertaking a full renovation. Understanding what each price point actually delivers helps you choose appropriately.
How to Choose the Right Designer for Your Budget
Look at their portfolio carefully — does their aesthetic match yours?
Check whether pricing is transparent on their website
Understand exactly what is included at each price point before committing
Ask to see examples of deliverables — mood boards, drawings, visualisations
Consider remote design packages if you want quality at a more accessible price point
