How Much Does an Interior Designer Cost in the UK?
Thinking about hiring an interior designer but unsure how much it will cost? Here's what you need to know about interior design fees, online interior design and what you can expect for your investment.
Hiring an interior designer can feel like a significant investment, particularly if you've never used one before.
You may be wondering:
How much does an interior designer cost?
Is interior design charged by the hour or by the room?
Is online interior design cheaper?
And perhaps most importantly:
What exactly am I paying for?
The answer isn't always straightforward because interior designers structure their fees in different ways.
In this guide, we'll explain the different ways interior designers charge, what can influence the overall cost and why online interior design can be an attractive option for homeowners looking for professional guidance without committing to a traditional full-service design service.
How Much Does an Interior Designer Cost?
There isn't one fixed price for interior design in the UK.
The cost can vary considerably depending on:
The size of your project
The number of rooms
The level of design support required
The experience of the designer
Whether the service is online or in-person
Whether project management is included
The furniture and finishes being specified
The complexity of the project
Some designers charge an hourly rate, while others offer fixed-fee packages for individual rooms or complete projects.
This means it's important to understand exactly what is included in a quotation rather than simply comparing prices.
How Do Interior Designers Charge?
There are several common pricing structures.
1. Hourly Rates
Some interior designers charge for their time.
This can work well if you only need a small amount of advice, such as help choosing paint colours, furniture or accessories.
The disadvantage is that it can sometimes be difficult to know exactly what your final cost will be if the project develops over time.
2. Fixed-Fee Packages
Many designers offer a fixed price for a defined service.
For example, you might purchase a package for:
One room
Two rooms
A whole home
A colour consultation
A furniture layout
A design concept
The advantage is that you know what you're investing from the beginning.
It also makes it easier to choose a service that matches your requirements and budget.
3. Percentage-Based Fees
For larger traditional interior design projects, some designers may charge a percentage based on the overall project or procurement value.
This is more commonly associated with full-service interior design and larger renovation projects.
If you're considering this type of service, always ask exactly how the percentage is calculated and what is included.
How Much Does Online Interior Design Cost?
Online interior design is generally structured differently from traditional interior design.
Because the designer isn't required to make repeated visits to your home, online services can offer a more streamlined approach.
Rather than paying for extensive site visits or ongoing project management, you may receive a defined design package containing everything you need to implement the scheme yourself.
Depending on the designer and package, this can include:
Initial consultation
Mood board
Colour palette
Furniture layout
Furniture recommendations
Lighting suggestions
Accessories
Product links
Shopping list
Styling guidance
Design presentation
Revisions
The important question isn't simply:
"How much does it cost?"
It's:
"What am I getting for my investment?"
What Influences the Cost of Interior Design?
Two rooms of exactly the same size can have completely different design costs.
Why?
Because the requirements may be very different.
The Scope of the Project
Designing a bedroom will usually involve a different level of work from designing an entire house.
The Level of Support
Do you simply need a design concept, or do you want someone to source products, place orders and manage trades?
The Existing Room
If you're keeping your existing furniture, the designer may need to work creatively around what you already own.
If you're starting from scratch, there may be considerably more furniture and product selection involved.
Your Budget
A good designer should understand your budget from the beginning.
This allows the design to be created around what is realistic for you rather than suggesting products that aren't achievable.
Do You Need a Full-Service Interior Designer?
Not necessarily.
This is something many homeowners don't realise.
You don't always need someone to manage every aspect of your project.
Perhaps you:
Enjoy shopping yourself
Are happy to organise trades
Want to be involved in the process
Simply don't know where to start
Need help bringing your ideas together
Want someone to create a cohesive scheme
In this situation, an online interior design service could be a great fit.
You get the professional design expertise, while remaining in control of implementing the project.
Is Online Interior Design Cheaper?
It can be a more accessible alternative to traditional full-service interior design, particularly for homeowners who don't require ongoing project management or frequent site visits.
However, it shouldn't simply be viewed as the "cheaper" version of interior design.
The real difference is often how the service is delivered.
With online interior design, you may receive a complete design plan and then implement it yourself.
That gives you flexibility and control over the pace and budget of your project.
What Should You Look for When Comparing Interior Designers?
Price shouldn't be the only consideration.
Before choosing a designer, look at:
Their Portfolio
Does their work demonstrate the style and quality you're looking for?
Their Process
Do you understand what will happen from the moment you book?
What's Included
Make sure you understand exactly what you'll receive.
Revisions
Check whether you can request changes to the initial design.
Product Sourcing
Will you receive direct links to recommended products?
Communication
How will you communicate with your designer throughout the process?
Their Design Philosophy
Most importantly, do they understand what you want your home to feel like?
Is Hiring an Interior Designer Worth the Investment?
For many homeowners, the value isn't simply in having someone choose furniture or colours.
It's in avoiding expensive mistakes.
How many times have you bought something because you loved it in the shop, only to discover it doesn't quite work in your room?
Or painted a wall and realised the colour looks completely different in natural light?
Or spent hours searching for the "perfect" sofa, rug or lighting, only to become overwhelmed by the choices?
An interior designer can bring clarity and direction to those decisions.
The result isn't simply a prettier room.
It's a room where the decisions work together.
How Mood & Mantel Approaches Interior Design
At Mood & Mantel, we believe good interior design should feel personal, practical and considered.
Your home shouldn't look like everyone else's.
Our approach begins with understanding you—your lifestyle, your preferences, your existing home and how you want the space to feel.
From there, we create a design that brings everything together into a cohesive scheme.
Whether you're looking to transform one room or make changes throughout your home, our online interior design service gives you a clear design direction without the commitment of traditional full-service interior design.
Before You Hire an Interior Designer
Before making a decision, ask yourself three questions:
What do I actually need help with?
Do you need a complete design or simply guidance?
How involved do I want to be?
Would you prefer someone to manage everything, or do you enjoy implementing the design yourself?
What is my realistic budget?
Consider both your design investment and the cost of implementing the recommendations.
Having clarity on these three things will make it much easier to choose the right service.
