Hiring a luxury interior designer in London is about far more than selecting fabrics, finishes, or colour palettes. It is a comprehensive process that combines creativity, technical expertise, and meticulous coordination to deliver a space that feels refined, functional, and truly personal. Whether you are renovating a private residence or upgrading a commercial property, luxury design focuses on creating environments that stand the test of time.
As demand for high-end interiors continues to grow in 2026, understanding the cost structure behind luxury design services is essential. Knowing where your investment goes allows you to plan confidently and appreciate the long-term value that expert design brings.
In this guide, we break down typical pricing, the factors that influence costs, and the value you receive when working with Luxury Interior Designers London such as Oraanj Interiors.
How Interior Designers Charge: Hourly, Percentage, Flat Fee & Per Square Foot
Interior designers in London typically use one of four pricing models, and understanding the difference helps you compare quotes on a like-for-like basis.
Hourly rate – Common for consultations, smaller projects, or ongoing advisory work. Rates generally sit between £75 and £300 per hour depending on seniority and studio reputation, with senior principal designers commanding the higher end.
Percentage of project value – The most common model for full-service residential projects. Designers typically charge 10%–25% of the total project cost (furnishings, joinery, materials, and contractor work), which aligns the designer’s incentive with sourcing quality rather than simply billing hours.
Flat or fixed project fee – Agreed upfront for a clearly defined scope, such as a single room or a fixed design package. This offers cost certainty but works best when the brief is unlikely to change significantly once underway.
Per square foot – More common on larger residential or commercial schemes, where fees might range from £15–£60+ per square foot depending on the level of bespoke detailing involved.
Many studios, including Oraanj Interiors, blend these models, for example, a flat consultation fee followed by a percentage-based fee for full project delivery. Always ask a prospective designer which model applies to your project, and whether furniture and contractor costs are included in the percentage or billed separately.
1. Average Cost of a Luxury Interior Designer in London
The cost of hiring a luxury interior designer in London varies depending on the scale, complexity, and level of customisation required. Typically, fees range between £75 and £300 per hour, or approximately 10%–25% of the overall project value. Many studios also offer tailored design packages based on the specific needs of each client.
High-end projects often require a more involved design process, including detailed planning, bespoke elements, and coordination with multiple consultants and contractors. As a result, fees reflect the time, expertise, and resources invested in delivering a refined outcome.
For luxury residential projects, indicative costs often fall within the following ranges:
- One-bedroom apartment: £10,000–£25,000
- Two- to three-bedroom home: £30,000–£70,000+
- Large-scale or fully bespoke homes: £100,000+
These figures typically relate to comprehensive Interior Design London services, where the designer is involved throughout the project lifecycle. For an overview of what this includes, explore our Luxury Package for fully tailored solutions.
2. What’s Included in the Fee?
When you engage a luxury interior designer, you are investing in a holistic service rather than a purely decorative one. Fees usually cover a wide range of professional services designed to ensure cohesion, quality, and precision from concept to completion.
A typical luxury design package may include:
- In-depth design consultation and concept development
- Detailed space planning and architectural integration
- Curated material palettes, finishes, and specifications
- Bespoke furniture concepts and detailing
- Visual tools such as mood boards and three-dimensional visuals
- Coordination of sourcing, ordering, and installation
Studios offering full service interior design manage every stage of the process, allowing clients to enjoy a seamless experience while ensuring the final result aligns with the original vision. This integrated approach is particularly valuable for homeowners planning projects with a bathroom renovation company in London, as it reduces risk, minimises errors, and maintains design integrity throughout.
3. Key Factors That Affect Pricing
Luxury interior design pricing is influenced by several variables, each contributing to the overall scope and complexity of the project.
Location plays a significant role, as properties in prime central London often involve higher labour costs, access restrictions, and logistical challenges.
Project scope is another key factor, including the number of rooms, level of detail, and degree of customisation required.
Timelines can also impact pricing, with accelerated schedules sometimes incurring additional fees to accommodate fast-tracked design or sourcing.
Materials and suppliers are particularly influential, as bespoke or imported elements often require specialist craftsmanship and longer lead times.
Projects involving bespoke joinery and handcrafted detailing typically sit at the higher end of the pricing scale due to the precision and expertise involved.
Interior Design Costs by Room and Property Type
Beyond whole-home estimates, many clients want to understand cost on a room-by-room or per-square-foot basis, particularly when phasing a renovation.
Indicative figures for London-based luxury projects:
- Single bedroom refresh: £8,000–£20,000, depending on joinery, lighting, and furnishing quality
- Kitchen redesign: £20,000–£60,000+, reflecting cabinetry, worktops, and integrated appliances
- Living or reception room: £10,000–£30,000
- Cost per square foot (design fee only, excluding furnishings/contractor works): roughly £20–£80 per sq ft, rising toward the top of that range for bespoke joinery, imported materials, or listed-building constraints
- Flat or apartment (full design service): typically falls within the £10,000–£25,000 one-bedroom band outlined earlier, scaling with square footage and number of reception rooms
- Condo/leasehold considerations: building regulations, service lift access, and management company approvals can add cost and lead time compared with a freehold house
These figures are a helpful planning benchmark, but the most accurate number for your space comes from a walkthrough consultation, since finishes, structural changes, and lead times vary considerably project to project.
4. Value vs. Investment: Is It Worth It?
While luxury interior design represents a significant investment, the value it delivers extends far beyond visual appeal. A thoughtfully designed space can transform the way you live or work, improving comfort, functionality, and overall well-being.
From a financial perspective, professionally designed interiors often increase property value and market desirability. Buyers and tenants recognise the quality of well-planned layouts, premium finishes, and cohesive design narratives.
Beyond monetary returns, clients frequently highlight the emotional value of living in a space that reflects their personality and lifestyle. Expert designers integrate project management to ensure every detail is executed flawlessly, allowing clients to enjoy the process without unnecessary stress.
5. Tips for Getting the Best Value
To maximise the return on your investment, it’s important to approach luxury interior design with clarity and foresight.
Start by setting a realistic budget that accounts for design fees, furnishings, and contingencies. Choosing a studio that prioritises transparency helps ensure expectations remain aligned throughout the project. Requesting a clear breakdown of costs allows you to understand how resources are allocated and where adjustments can be made if needed.
Focusing on timeless design rather than short-lived trends also enhances long-term value. Elements such as bespoke joinery design and high-quality finishes may require a higher initial investment but often prove more cost-effective over time due to durability and enduring appeal.
Studios that offer integrated procurement services streamline sourcing and logistics, ensuring products arrive on time, meet quality standards, and align with the approved design.
Interior Design Consultation Fees
Most luxury studios begin with a paid initial consultation rather than a free estimate, a reflection of the time and expertise involved in assessing a space properly.
A typical London consultation fee ranges from £150 to £500 for an initial in-person or virtual session, during which the designer reviews the space, discusses the brief, and outlines a broad scope and indicative budget. Some studios offer a more in-depth paid design audit, generally £500–£1,500, which includes preliminary concept direction and a written scope of works.
Importantly, many studios, Oraanj Interiors included, credit some or all of the consultation fee against the final project cost if you proceed, meaning it functions less as a standalone charge and more as a qualifying first step. When comparing designers, always ask directly whether the consultation fee is deductible from the full project fee, as this varies by studio and materially affects the overall cost comparison.
Commercial & Office Interior Design Costs in London
Commercial interior design, office interior design, restaurants, hotels, salons, and retail spaces, follows a different cost structure to residential work, largely driven by square footage, compliance requirements, and faster turnaround expectations.
Indicative London ranges:
- Office interior design: £40–£150 per sq ft, depending on whether the scope includes full fit-out (partitioning, M&E coordination) or a lighter refurbishment of an existing shell
- Restaurant or hospitality interiors: £80–£250+ per sq ft, reflecting bespoke joinery, specialist lighting, and kitchen/back-of-house coordination
- Retail and boutique spaces: £60–£200 per sq ft, varying with brand-specific detailing and shopfitting requirements
- Hotel interiors: typically quoted per room or per key, often £15,000–£60,000+ per room for luxury properties, in addition to public realm and back-of-house design fees
- Salons and smaller commercial units: generally £15,000–£50,000 for a full design and fit-out of a single unit, depending on size and specification
Commercial projects also tend to involve additional professional fees, architects, M&E consultants, and building control sign-off, which residential projects may not require to the same extent. As with residential work, requesting a clear, itemised proposal before committing helps avoid scope creep once works are underway.

Understanding the cost of hiring a luxury interior designer in London empowers you to plan effectively and invest with confidence.
