How to Hire an Interior Designer in the UK

Hiring an interior designer can turn a stressful renovation into a smooth, well-planned project, and it can turn an ordinary home into one that feels personal, practical and beautiful. A good designer brings creative vision, technical knowledge, supplier contacts and project management skills, and often helps you avoid costly mistakes. In the UK, though, anyone can call themselves an interior designer, fees vary widely, and contracts can be confusing.

This guide explains how to hire an interior designer in the UK step by step: what designers do, whether you need one, how fees work and what they cost, BIID registration, where to find designers, questions to ask, contracts, procurement and trade discounts, VAT, insurance, planning and building rules, red flags, and how to get the best value.

What Does an Interior Designer Do?

An interior designer plans and creates functional, attractive interiors. Depending on the project, services can include:

• Understanding your brief, lifestyle and budget
• Space planning and layout design
• Concept boards, mood boards and colour schemes
• Lighting, electrical and joinery design
• Kitchen and bathroom design
• Selecting furniture, fabrics, finishes and accessories (often called FF&E: furniture, fixtures and equipment)
• Technical drawings and specifications
• Getting quotes from contractors and suppliers
• Ordering, tracking and managing deliveries (procurement)
• Coordinating builders and trades
• Site visits and quality checks
• Final styling and installation

Interior Designer vs Interior Decorator vs Architect

Professional	Main Focus	Typical Work
Interior designer	Space planning, function and aesthetics	Layouts, lighting, joinery, kitchens, bathrooms, FF&E
Interior decorator	Decoration and styling	Colours, fabrics, furniture, accessories
Architect	Building structure and design	Extensions, structural changes, planning applications
Interior architect	Interior spaces with structural elements	Reconfiguring layouts, major internal changes

In the UK, “architect” is a legally protected title, but “interior designer” is not. The BIID explains that the title is not protected, unlike the title ‘architect’ which is subject to government regulation. This means that anyone can call themselves an interior designer.

Do You Need an Interior Designer?

When Hiring a Designer Makes Sense

• Full-house renovations or refurbishments
• Kitchen or bathroom redesigns
• Extensions where interiors need to be planned
• Period homes needing a sensitive approach
• When you lack time to manage suppliers and trades
• When you are struggling with layout, lighting or style
• High-budget projects where mistakes would be costly
• Preparing a home for rental or sale

When You Might Not Need Full Service

• Repainting one room
• Simple furniture updates
• If you enjoy researching and sourcing yourself

In these cases, a consultation, a fixed design package or online e-design may be enough. As one UK guide notes, if you want direction and will do the legwork, an hourly rate or a fixed package will cost a tenth as much.

Types of Interior Design Services

Service Level	What You Get	Best For
Consultation	A one-off visit with advice	Quick ideas, colour advice, layout tips
Design-only package	Mood boards, layouts, product lists	DIY-confident homeowners
E-design / online design	Remote design packs delivered digitally	Single rooms, tighter budgets
Full design service	Design plus drawings and specifications	Major projects
Full service with project management	Design, procurement, trade coordination, installation	Large renovations, busy clients
Turnkey service	Designer handles everything until the home is ready	Second homes, investors, rental properties

Online design has widened access. One online design service says it has democratised the industry as now anyone and everyone can afford to hire a professional interior designer for their home transformation.

How Much Does an Interior Designer Cost in the UK?

How UK Designers Charge

There is no single fee model. 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. Combining methods is common: In the BIID’s own member survey, just over half of designers reported using more than one method at once.

Hourly Rates

The BIID’s survey gives a useful benchmark. The survey asked for the hourly rate of the most senior designer in the practice, and this was up to £75 for 59% of respondents, and £76 to £150 for 41% of respondents.

Some guides quote much higher figures for top London studios and initial consultations. One claims interior designer fees in the UK range from £180 to £450 per hour for consultations, with full-service design packages starting at £2,000 per room. Prices depend heavily on experience, reputation and location.

The advantage of hourly rates is flexibility: An hourly rate allows for the brief to be changed or enlarged since the extra hours involved can be charged at the pre-agreed rate. The risk is cost creep. One guide warns: Paying hourly for a six-month project is how budgets run away.

Fixed Fees

A fixed fee is a set price for an agreed scope. In the BIID survey, 21% used a fixed fee, 18% an hourly rate, 6% a percentage of total project costs. Fixed fees make budgeting easier but need a clear scope.

Percentage of Project Cost

Some designers charge a percentage of the total project budget. One guide notes designers charge a percentage rate for the total cost of a project, which is as low as 10% and but as high as 25%. This works for large projects but can be harder to predict. The BIID’s professional guidance notes that FF+E procurement is ideally not included in a percentage fee of the build cost.

Combination Fees

Many projects mix models. For example, 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.

Fee Model Comparison

Fee Model	Pros	Cons	Best For
Hourly / day rate	Flexible, pay only for time used	Hard to cap	Consultations, small jobs
Fixed fee	Clear budget	Extra work costs more	Defined rooms or packages
Percentage of project	Scales with project size	Less predictable	Large renovations
Per room	Easy to understand	May not suit complex homes	Single rooms
Combination	Matches each project stage	More complex to compare	Most full projects

Match the Fee Model to the Job

Pay hourly or take a day rate for advice and small jobs; use fixed fees or a percentage for full renovations.

London vs Rest of the UK

Hiring an interior designer in London costs more than it does anywhere else in the UK, and the figure you pay depends almost entirely on which fee model your designer uses.

Remember the Wider Budget

Designer fees are only part of the cost. You also pay for trades, materials, furniture and finishes. For example, Checkatrade reports that the cost to paint a room averages around £450. Meanwhile, painting a 5-bed house could cost in the region of £6,000.

Sample Budget Breakdown

Cost Area	What It Covers
Design fees	Designer’s time and services
Building and trades	Builders, electricians, plumbers, decorators, joiners
Materials and finishes	Flooring, tiles, paint, wallpaper, worktops
Furniture and lighting	Sofas, beds, tables, lamps, fittings
Soft furnishings	Curtains, blinds, rugs, cushions
Contingency	Usually 10–15% for unexpected costs
VAT	Where applicable

BIID Registration: Why It Matters

What Is the BIID?

The British Institute of Interior Design (BIID) is the UK’s professional body for interior designers. You can find interior designers and interior design practices via the BIID, which is the UK’s only professional institute for interior designers.

What BIID Registration Means

Because the title is unprotected, BIID registration is a useful quality signal. All BIID Registered Interior Designers have been assessed based on their education, experience, skills and professional competence, prior to being accepted for registration. Registered designers are required to hold professional indemnity (PI) insurance, adhere to the BIID Code of Conduct.

The requirements are demanding. To become registered, a designer must have education and professional experience adding up to six years (or six years of work experience on its own), pass a professional review of their competence.

Unregistered Designers Can Still Be Excellent

Many strong London studios are not registered, so judge them on references, contract clarity and insurance as well. If a designer is not registered, ask directly about their qualifications and insurance.

Step-by-Step: How to Hire an Interior Designer

Step 1: Define Your Project

• Which rooms or areas are involved?
• Is it decoration only, or are there structural, electrical or plumbing changes?
• What style do you like? Collect images from Pinterest, Instagram, magazines and Houzz
• What must the space do for you (storage, working from home, entertaining)?
• What is your timeline?

Step 2: Set a Realistic Budget

Decide your total budget, including design fees, trades, furniture and contingency. Be honest with designers about it, because it shapes every recommendation.

Step 3: Find Potential Designers

Source	Notes
BIID directory	Searchable list of members and registered designers
Personal recommendations	Friends, family, neighbours, estate agents
Houzz	Portfolios and reviews
Instagram and Pinterest	View real projects and style
Magazines and design awards	Established studios
Local architects and builders	Often recommend designers they trust
Online design platforms	For e-design and smaller budgets

Step 4: Review Portfolios

• Do you like their style?
• Have they done projects similar to yours in size and type?
• Do their projects look lived-in and practical, or only staged?
• Do they work with period properties or new-builds?

Step 5: Shortlist and Hold Initial Calls

Shortlist three designers. Many offer a free or paid initial call or consultation.

Step 6: Ask the Right Questions

(See the full list below.)

Step 7: Request Written Proposals

Ask each designer for a written proposal that includes:

• The scope of services
• Fee structure and estimated total fees
• Payment schedule
• Timeline and key stages
• How procurement and supplier discounts work
• How changes and extra work are charged
• Insurance details

Step 8: Check References and Credentials

• Speak to past clients
• Visit completed projects if possible
• Check BIID status, reviews and online presence
• Confirm professional indemnity insurance

Step 9: Sign a Clear Contract

Never start a project without a written contract or letter of appointment.

Step 10: Stay Involved

Attend design presentations, give clear feedback, approve key decisions promptly and keep communication open.

Questions to Ask an Interior Designer

Experience and Style

1. How long have you been practising?
2. Have you done similar projects in size, type and budget?
3. Can I speak to previous clients?
4. Are you BIID registered or a member of another professional body?
5. What is your design process?

Fees and Costs

6. How do you charge: hourly, fixed fee, percentage or a mix?
7. What is included in your fee, and what is extra?
8. Are your fees subject to VAT?
9. How do you charge for changes to the brief?
10. Do you charge for travel, printing or samples?
11. What is your payment schedule?

Procurement and Discounts

12. Do you buy furniture and materials on my behalf?
13. Do you receive trade discounts, and are they passed on to me?
14. Do you add a mark-up or handling fee on purchases?
15. Who owns items if a supplier fails or goods arrive damaged?

Project Management

16. Will you manage contractors, or should I hire them myself?
17. How often will you visit the site?
18. Who is my main point of contact?
19. How do you handle delays and problems?
20. What is the expected timeline?

Insurance and Contracts

21. Do you have professional indemnity and public liability insurance?
22. What contract do you use?
23. What happens if I want to end the contract early?

Understanding Procurement, Trade Discounts and Mark-Ups

Procurement means ordering and managing furniture, lighting, fabrics and other items. Designers handle it in different ways:

Model	How It Works
Client buys directly	Designer specifies items; you pay suppliers directly
Designer buys at trade price, passes on discount	You pay the trade price plus a procurement fee
Designer buys at trade price, sells at retail	Designer keeps the discount as their fee
Designer adds a mark-up	Items are charged at cost plus a percentage

Transparency matters. Ask clearly how discounts and mark-ups work before signing.

VAT on Interior Design Fees

VAT can add a significant amount to your costs. 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.

Also check VAT on furniture, materials and trade work.

Contracts: What Should Be Included?

A good interior design contract or letter of appointment should cover:

Section	What It Covers
Parties	Names and addresses of client and designer
Scope of services	Exactly what the designer will and will not do
Fees	Fee structure, rates and estimated totals
Payment schedule	Deposits, stage payments, final payment
Expenses	Travel, printing, samples, couriers
Procurement terms	How purchases, discounts and mark-ups work
Timeline	Key stages and expected completion
Changes and variations	How extra work is approved and charged
Ownership of designs	Who owns drawings and concepts
Insurance	PI and public liability details
Termination	How either party can end the contract
Dispute resolution	Mediation or other processes

Clear fee information is part of good practice. BIID members are encouraged to be transparent about their fee structure; for example, whether they have an hourly rate or if there is a fixed charge for the whole project.

The Interior Design Process: What to Expect

Stage	What Happens
1. Initial consultation	Discuss the brief, budget, style and timeline
2. Proposal and appointment	Designer sends a fee proposal; contract signed
3. Survey and measurements	Designer measures and photographs the space
4. Concept design	Mood boards, colour schemes, layout options
5. Developed design	Detailed layouts, lighting, joinery and material selections
6. Technical design	Drawings and specifications for trades
7. Tendering	Quotes from builders and suppliers
8. Procurement	Ordering furniture, finishes and fittings
9. Construction / installation	Works on site, coordinated by the designer or contractor
10. Styling and handover	Final styling, snagging and project completion

Planning, Building Regulations and Legal Considerations

Interior designers may help coordinate approvals, but you as the homeowner remain responsible for meeting legal requirements.

Requirement	When It Applies
Planning permission	Extensions, some external changes, change of use
Listed Building Consent	Most changes to listed buildings, including some internal work
Conservation area rules	External changes in protected areas
Building Regulations approval	Structural work, electrics, plumbing, drainage, fire safety, insulation
Party Wall Act agreements	Work on shared walls with neighbours
Leasehold permissions	Flats often need freeholder or management company consent
Electrical certification	Notifiable electrical work in England and Wales must meet Part P rules
Gas Safe registration	Any gas work must be done by a Gas Safe registered engineer

Always check with your local council, building control and, for flats, your lease before major work starts.

Insurance Considerations

Designer’s Insurance

• Professional indemnity (PI) insurance: covers claims arising from design errors or professional advice
• Public liability insurance: covers injury or damage during site visits or installation

Your Insurance

• Tell your home insurer before major renovations, because some policies change cover during building works
• Check that contractors carry their own public liability insurance
• Update your contents cover for valuable new furniture, art or antiques
• Consider specialist cover for listed or high-value homes

Red Flags When Hiring a Designer

Red Flag	Why It’s a Concern
No written contract	No protection if things go wrong
Vague fee structure	Risk of unexpected costs
Large upfront payment for the whole project	Financial risk if the designer fails to deliver
No references or portfolio	Can’t verify quality
No professional insurance	No cover for mistakes
Unclear procurement terms	Hidden mark-ups possible
Pressure to sign quickly	Poor practice
Poor communication early on	Likely to get worse during the project
Style doesn’t match yours	Result may not feel like your home

How to Get the Best Value

1. Be clear about your brief and budget from the start
2. Choose the right service level: don’t pay for full service if you only need ideas
3. Make decisions promptly: delays cost time and money
4. Limit changes once designs are agreed
5. Ask about trade discounts and how they are shared
6. Mix investment and budget pieces: spend on sofas, kitchens and lighting; save on accessories
7. Reuse existing furniture where possible
8. Keep a 10–15% contingency for surprises
9. Get several quotes for building work
10. Keep records of all decisions and approvals

Paying for Your Project

• Savings: the simplest and cheapest option
• Remortgaging or further advances: for large renovations (compare rates and fees)
• Home improvement loans: for medium-sized projects
• Retail finance: some furniture suppliers offer interest-free credit; read the terms carefully
• Staged payments: agree payments tied to milestones rather than paying everything upfront

Paying larger purchases by credit card can give extra protection under Section 75 of the Consumer Credit Act for qualifying purchases, so check eligibility with your card provider.

Hiring an Interior Designer for Rental or Investment Properties

Landlords and investors use designers to:

• Furnish properties quickly for letting
• Create attractive interiors that justify higher rents
• Choose durable, easy-to-clean finishes
• Prepare serviced accommodation or holiday lets
• Stage homes for sale

Many designers offer turnkey furnishing packages for rental properties, often at fixed prices.

Final Thoughts

Hiring an interior designer in the UK can save time, avoid costly mistakes and create a home that truly works for you. Because anyone can use the title, check credentials carefully. BIID registration signals assessed competence and insurance, but references, portfolios and contract clarity matter just as much. Designers charge by hourly or day rates, fixed fees, percentages of project cost or a mix, and London rates are typically higher. Choose a fee model that suits your project, get written proposals, ask clear questions about procurement, discounts and VAT, and always sign a detailed contract. With a clear brief, a realistic budget and the right designer, your project is much more likely to finish on time, on budget and exactly as you imagined.
