Ask five interior designers what a project costs and you'll get five different answers, most of them vague. That vagueness is usually the real reason people hesitate to enquire, not the number itself, but not knowing what the number actually means. This guide sets out interior design costs in London for 2026 clearly, room by room and structure by structure, so you know what you're looking at before you speak to anyone.
The Short Answer
Interior design costs in London vary 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 services: from £295 per room
Full-service room design: £800–£3,000+ per room
Full residential project (London): £5,000–£20,000+
Hourly rates: £35–£450 per hour depending on experience
The range exists because interior design is not one thing. A styled 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
Fixed package pricing. The most transparent option. A set fee for a defined scope, typically a concept board, furniture layout, material selections and a shopping list. Common among online design services, where the scope and deliverables are agreed before work begins.
Hourly rate. London designers typically charge between £50 and £450 per hour, with more experienced designers or those on complex bespoke projects at the higher end. Hourly billing suits small, clearly defined tasks, but on larger projects it can be difficult to predict the final cost.
Percentage of project value. Some designers charge 10-25% of the overall project value, reflecting the full scope of their involvement from design through to delivery.
What Affects Interior Design Cost?
Location within London. Prime central areas, Mayfair, Chelsea, Notting Hill, Hyde Park Gardens, often carry higher logistics costs and access challenges, which can push design fees up.
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 and contractor coordination sits at the other.
Bespoke elements. Projects involving bespoke joinery, custom furniture and handcrafted detailing sit at the higher end. They require more design time, more detailed drawings and closer coordination with specialist makers.
Online vs in-person. Remote design services typically cost less than in-person, since they remove travel time and site visit costs from the equation, without compromising on design quality. Kachi Interiors works with clients remotely and in person, delivering full residential design across London and worldwide.
A Realistic Budget Guide by Room
Room | Online / Remote | Full Service |
Bedroom | From £295 | £800–£2,500 |
Living room | From £395 | £900–£2,500 |
Bathroom | From £795 | £1,500–£4,000 |
Kitchen | From £795 | £2,000–£8,000+ |
Full home (London) | POA | £5,000–£20,000+ |
These figures cover design fees only, not furniture, materials, finishes or contractor costs.
What Should Be Included at Each Price Point?
From £295–£495 per room. Expect a concept board, scaled furniture layout, colour and material direction and a curated shopping list. Suited to clients with a clear sense of their own style who want professional direction rather than full design development.
From £800–£1,500 per room. This tier should include everything above plus 2D and 3D visuals, refined furniture and lighting selections, and design support throughout. You see the room before you commit to buying anything, which is where the real value lies.
From £1,500+ per room. At this level, expect full technical drawings, bespoke joinery design, room elevations, material and finish specifications, and closer support during execution. Appropriate for renovations and rooms with custom-built elements.
Is It Worth It?
A well-considered interior design can meaningfully increase a home's resale value, particularly when the improvements focus on layout, flow and durable material choices rather than purely decorative changes.
The real question isn't whether interior design is worth it, it's whether you're getting the right level of service for your project. Someone 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.
