Interior designer fees confuse many UK homeowners. Ask three designers to price the same project and you may get three very different quotes: one hourly, one as a percentage of your budget, and one as a fixed price per room. On top of that come procurement mark-ups, trade discounts, VAT, expenses and payment schedules. Without understanding how fees work, it is hard to compare quotes fairly or know whether you are getting good value.
This guide focuses only on fees. It covers every UK fee model in detail, typical price ranges, what drives costs up or down, procurement mark-ups and trade discounts, VAT, extra charges, worked cost examples, how to compare quotes, payment schedules, negotiation tips, and whether a designer can pay for themselves.

Why Interior Designer Fees Vary So Much
No single pricing system exists in the UK. One London guide sums up the problem: Ask three interior designers in London how they charge and you can get three completely different answers. One quotes an hourly rate, one wants a percentage of your build budget, and one offers a fixed package per room. None of them is wrong.
The BIID confirms this. There is no single fee structure when employing a professional interior designer. ‘Charges will vary from studio to studio,’
Main Factors That Affect Fees
| Factor | Effect on Fees |
|---|---|
| Designer experience and reputation | Senior and award-winning designers charge more |
| Location | London and the South East are typically highest |
| Project size | Whole-house projects cost more overall but may be cheaper per room |
| Scope of services | Design-only is cheaper than full project management |
| Complexity | Period homes, bespoke joinery and structural work raise fees |
| Number of revisions | More design changes mean more hours |
| Procurement | Ordering and managing purchases adds cost |
| Timeline | Rush projects may cost more |
| Site visits | Frequent visits increase fees, especially with travel |
The Five Main Fee Models
According to the BIID, designers price work in five broad ways: a fixed fee, an hourly rate, a daily rate, a percentage of total project costs, or a combination of these.
1. Hourly Rate
The designer charges for each hour worked on your project.
Typical UK rates: The BIID’s survey of its members found that the hourly rate of the most senior designer in the practice was up to £75 for 59% of respondents, and £76 to £150 for 41% of respondents.
Some designers, especially in London, charge more. One online design company claims fees range from £180 to £450 per hour for consultations, while another guide puts typical hourly rates between £25 and £150 an hour depending on how much experience they have and where they are based in the UK. These differences show how much rates vary.
| Pros | Cons |
|---|---|
| Pay only for the time used | Hard to predict the total |
| Flexible if the brief changes | Costs can rise quickly on long projects |
| Good for consultations and small jobs | Requires trust and clear time records |
Best for: consultations, colour advice, small rooms, specific tasks.
2. Day Rate
Similar to hourly, but charged per day. It is common for site work, sourcing trips and freelance designers. Industry data for freelance designers working with studios puts day rates at Midweight freelance designer: £250–£320 per day and Senior freelance designer: £330–£400 per day. Rates charged directly to homeowners by established studios are often higher.
3. Fixed Fee
A set price for a defined scope, such as designing one room or a whole flat. It is easy to budget against because you know the number before you start. The trade-off is that the scope is tightly defined, so extra revisions or added rooms cost more.
| Pros | Cons |
|---|---|
| Clear upfront cost | Extra work costs more |
| Easy to compare quotes | Requires a precise brief |
| No surprise bills for agreed work | Designers may build in a buffer |
Typical range: Fixed per-room fees vary widely. One guide gives Flat Fee Pricing (Per Room) £1,500 – £10,000.
4. Percentage of Project Cost
The designer charges a share of the total project budget. Published UK figures vary:
- One guide states UK percentages usually fall between 10 and 20 per cent of the overall budget, and luxury London projects can run from 10 to 25 per cent.
- Another compiled reference shows 6% to 10% (BIID reference); some quote 10% to 20% as the design fee.
- One designer says traditional design can cost roughly 5-10% of your overall project costs and can start from £15,000 upwards.
| Pros | Cons |
|---|---|
| Fee scales with project size | Final cost unclear until the project ends |
| Suits large renovations | Designer earns more if you spend more |
| Covers ongoing involvement | Need clarity on what “project cost” includes |
Important: clarify whether the percentage applies to build costs, furniture, or both. The BIID’s guidance notes that FF+E procurement is ideally not included in a percentage fee of the build cost.
5. Combination Fees
Most full projects mix models. In the BIID’s member survey, just over half of designers reported using more than one method at once. A common pattern is a fixed design fee plus a percentage on procurement. The BIID’s professional guide adds: at feasibility stage an hourly rate or fixed fee is appropriate. Once a schedule of design services has been established, a percentage fee works well.
Other Pricing Methods
| Method | How It Works |
|---|---|
| Per square metre | A rate per m² of floor area |
| Retainer | An upfront deposit, deducted from later fees |
| E-design packages | Fixed online design per room |
| Consultation packages | A set fee for a home visit and advice |
Typical UK Fee Ranges at a Glance
| Service | Typical Range |
|---|---|
| Senior designer hourly rate (BIID survey) | Up to £75 for most; £76–£150 for many |
| Premium London consultation | Can exceed £150 per hour |
| Freelance designer day rate | About £250–£400 per day |
| E-design per room | from roughly £159 at the budget end up to £695 or more per room |
| Fixed fee per room (full design) | About £1,500 to £10,000+ |
| Percentage of project cost | Roughly 5–20%, higher for luxury London projects |
| Procurement mark-up | Commonly 10–15% on sourced items, sometimes more |
These figures are indicative only. Always get written quotes.
E-Design and Online Packages
E-design is the most affordable way to get professional help. One designer notes that e-design can typically cost anywhere from £500 per room for a basic design proposal, sometimes more if you need more bespoke support or drawings. You might spot some designers or businesses offering an e-design package for less than £250 per room.
What E-Design Usually Includes
- An online questionnaire and video consultation
- Mood boards and concept designs
- Floor plans and layouts
- A shoppable product list
- Limited revisions
What It Usually Doesn’t Include
- Site visits
- Detailed technical drawings for builders
- Project management
- Procurement and installation
Procurement Fees, Mark-Ups and Trade Discounts
What Is Procurement?
Procurement means the designer orders, tracks and manages furniture, lighting, fabrics and finishes for you. This takes considerable time, so designers charge for it.
Common Procurement Models
| Model | How It Works |
|---|---|
| Client buys directly | You buy items yourself from the designer’s list |
| Trade price plus procurement fee | Designer buys at trade price and adds a handling fee |
| Retail price (designer keeps discount) | You pay retail; the designer keeps the trade discount |
| Cost-plus | Items charged at trade cost plus a set percentage |
Typical Mark-Ups
Designers who buy furniture and finishes on your behalf commonly add a trade mark-up, published at 10% to 15% of the sourced items. That is not hidden and it is not wrong. Homes & Gardens notes that this is sometimes higher: they may also charge you a percentage of the cost of any products they source, which is normally more than 15% of the trade or retail price.
SBID Guidance on Fair Procurement
The Society of British and International Interior Design (SBID) recommends that mark-ups should never cost clients more than retail. Its guidance states it should NOT cost the customer more to receive the discount than to purchase at full retail. It also cautions against designers who charge no design fee and keep all discounts: the client may receive products where best discounts are available rather than the most appropriate product recommendations for the project.
Trade Discounts Can Offset Fees
Designers often access trade discounts from suppliers. One online service advertises access to trade-only discounts (up to 25% off). One designer notes: Some clients I’ve worked with in the past have saved more than my design fee in trade discounts.
Questions to Ask About Procurement
- Do you pass trade discounts on to me?
- What percentage do you add for procurement?
- Will I see the original trade invoices?
- Who handles deliveries, damages and returns?
- Can I buy items myself if I prefer?
VAT on Interior Design Fees
VAT can add 20% to your fees if your designer is VAT registered. If a designer’s turnover is above the UK VAT registration threshold of £90,000, they must charge VAT on top of their fee. Smaller studios may not be VAT registered, so check whether a quote includes it.
Tips:
- Always ask whether quotes include or exclude VAT
- Check VAT on furniture and materials separately
- Compare quotes on the same VAT basis
Additional Costs to Watch For
| Extra Cost | Description |
|---|---|
| Travel expenses | Mileage, train fares, parking, congestion charges |
| Printing and samples | Fabric samples, paint samples, printed drawings |
| Couriers and delivery coordination | Handling shipments |
| Extra revisions | Beyond the agreed number of design rounds |
| Additional site visits | Beyond those included |
| Specialist consultants | Lighting designers, structural engineers, architects |
| Photography | Professional photos of the finished project |
| Storage | Storing furniture before installation |
| Styling and accessories | Final styling day and decorative items |
Worked Cost Examples
These examples show how the same project might be priced under different models. They are illustrative only.
Example 1: Living Room Redesign (Design Only)
| Model | Calculation | Fee |
|---|---|---|
| Hourly | 25 hours × £75 | £1,875 |
| Fixed fee | Agreed room package | About £1,500–£3,000 |
| E-design | Online package | About £300–£700 |
Example 2: Whole-Flat Refurbishment
One London guide gives these comparisons for a 70 m² flat:
- Per square metre: a 70 square metre flat at £150/m2 = £10,500.
- Percentage: 15 per cent of £60,000 = £9,000.
Example 3: Large House Renovation With Procurement
- Build and finishes budget: £150,000
- FF&E budget: £50,000
- Design fee at 10% of build cost: £15,000
- Procurement mark-up at 12% of FF&E: £6,000
- Total design-related fees: about £21,000, plus VAT if applicable
Procurement margins can be significant. On a project with a £80,000 FF&E (furniture, fittings and equipment) budget, even a modest 15% procurement margin adds £12,000.
How Fees Differ by Location
| Region | Fee Level |
|---|---|
| London (prime areas) | Highest |
| South East (Surrey, Berkshire, Hertfordshire) | High |
| Major cities (Manchester, Bristol, Edinburgh, Birmingham) | Moderate to high |
| Smaller towns and rural areas | Generally lower |
| Online / remote designers | Often lowest |
Some designers also charge more for travel to distant projects.
How Fees Differ by Service Level
| Service Level | Relative Cost |
|---|---|
| One-off consultation | Lowest |
| E-design package | Low |
| Design-only (no procurement or management) | Moderate |
| Full design with drawings | Moderate to high |
| Full service with procurement | High |
| Turnkey (everything handled) | Highest |
Payment Schedules
Most designers ask for staged payments rather than a full payment upfront.
Typical Payment Structure
| Stage | Payment |
|---|---|
| Appointment / retainer | Deposit or first instalment |
| Concept design approval | Stage payment |
| Developed and technical design | Stage payment |
| Procurement | Deposits on furniture and materials |
| Installation and completion | Final payment |
Tips for Safe Payments
- Avoid paying the whole fee upfront
- Link payments to completed milestones
- Get receipts and invoices for every payment
- Pay larger supplier deposits by credit card where possible, which may give Section 75 protection on eligible purchases
- Keep written records of approvals
How to Compare Interior Designer Quotes
Quotes in different formats are hard to compare. Use this checklist:
| Compare | Questions |
|---|---|
| Scope | Do all quotes cover the same rooms and services? |
| Fee model | Hourly, fixed, percentage, or mixed? |
| Estimated total | What is the likely total fee? |
| Revisions | How many design rounds are included? |
| Site visits | How many visits are included? |
| Procurement | Discounts passed on? What mark-up? |
| VAT | Included or extra? |
| Expenses | Travel, samples, printing included? |
| Timeline | Realistic and clearly stated? |
| Payment terms | Staged or upfront? |
Tip: convert every quote into an estimated total for the same scope. Two designers’ prices can look similar until procurement mark-ups or expenses are added.
How to Negotiate Interior Design Fees
Negotiation is possible, but do it respectfully:
- Reduce the scope: handle sourcing or project management yourself
- Choose a fixed fee: for better budget certainty
- Agree a cap on hourly fees: with approval needed beyond a set number of hours
- Bundle rooms: designing several rooms together may lower the per-room cost
- Ask about off-peak timing: some designers have quieter periods
- Request transparent procurement: see trade invoices and agree a fixed mark-up
- Use e-design for simpler rooms: and full service only for complex spaces
Avoid pushing fees so low that the designer cannot give your project proper attention.
Is an Interior Designer Worth the Cost?
Ways a Designer Can Save You Money
- Avoiding expensive mistakes in layout, lighting and materials
- Access to trade discounts on furniture and finishes
- Better quotes from contractors through competitive tendering
- Efficient project management that reduces delays
- Making the most of space, which can reduce the need for extensions
- Choosing durable materials that last longer
- Improving home appeal for future sale or rental
When It May Not Be Worth It
- Very small projects with simple decoration
- If you enjoy design and have the time to research
- If your budget is very limited (e-design may be better)
Fees for Different Project Types
| Project Type | Typical Fee Approach |
|---|---|
| Single-room refresh | Hourly, fixed fee or e-design |
| Kitchen design | Fixed fee or percentage; sometimes included by kitchen suppliers |
| Bathroom design | Fixed fee or hourly |
| Whole-house renovation | Percentage or combination |
| New-build furnishing | Fixed package or procurement-based |
| Rental and investment properties | Fixed turnkey packages |
| Listed or period homes | Percentage or hourly, given the complexity |
| Commercial projects | Percentage, fixed or hourly, depending on scale |
Financing Your Interior Design Project
- Savings: the cheapest option
- Remortgage or further advance: for large renovations; compare rates, fees and long-term interest
- Home improvement loans: for medium-sized projects
- Credit cards: useful for purchase protection, but repay quickly
- Retail finance: interest-free deals from furniture retailers; read the terms carefully
- Staged budgeting: complete rooms in phases as budget allows
Insurance and Fees
- Check that your designer holds professional indemnity insurance, which covers errors in design advice
- Confirm public liability insurance for site visits and installations
- Update your home and contents insurance for valuable new furniture and art
- Tell your insurer before major building works begin
Red Flags on Fees
| Red Flag | Why It’s a Problem |
|---|---|
| No written fee proposal | Risk of surprise costs |
| Full payment upfront | High financial risk |
| Unclear procurement mark-ups | Hidden charges possible |
| Retail prices plus a mark-up | You may pay more than buying directly |
| No cap on hourly fees | Budget can run away |
| VAT not mentioned | Fees could be 20% higher than expected |
| Pressure to approve purchases quickly | Poor practice |
Final Thoughts
Interior designer fees in the UK vary widely because designers use different models: hourly or day rates, fixed fees, percentages of project cost, per-square-metre pricing, e-design packages and combinations. The BIID survey suggests most senior designers charge up to £75 an hour and many charge £76–£150, while premium London studios can charge more. Percentage fees commonly fall between about 5% and 20%, and procurement mark-ups often add 10–15% on sourced items. VAT, travel, samples and extra revisions can also increase costs. To get good value, define your scope clearly, convert every quote into a comparable total, ask detailed questions about procurement and VAT, insist on staged payments and a written contract, and choose the service level that truly matches your project.
