Interior Design

Interior designers plan and detail the inside of buildings - how spaces are laid out, how light and materials work, where services and furniture go - for clients such as developers, retailers, hotel groups, offices, hospitals, schools and private homeowners. The work combines drawing and 3D visualisation with practical decisions about budgets, building regulations, fire safety and what suppliers can actually deliver. Most designers work in a studio within an architecture practice, a specialist interiors consultancy, a contractor's design team, or in-house for a retail, hospitality or workplace brand.

Approximate graduate salary

Roughly £22,000–£28,000 to start is a reasonable approximation for a junior or graduate designer, with London and architecture-led or large commercial practices towards or above the upper end and small regional or residential studios often below it. This varies widely, and interior design generally pays less at entry level than many other graduate fields; pay improves noticeably with a few years of project experience.

What you'd actually do

Producing drawings in CAD (computer-aided design, commonly AutoCAD or Vectorworks) and increasingly in Revit - floor plans, reflected ceiling plans showing lighting and ceiling layouts, elevations and joinery details for bespoke furniture and fitted units
Building 3D models and renders (SketchUp, 3ds Max, Enscape, Lumion, Twinmotion) and putting them into presentation decks in InDesign so a client can see what a space will look like
Sourcing and specifying finishes, fabrics, lighting, flooring and furniture - requesting samples from suppliers, checking lead times, fire ratings and prices, and assembling physical sample boards
Updating the specification or schedule: a long document listing every product, its supplier, code, finish and quantity, which contractors price and order from

Sitting in on client meetings and design reviews, taking notes, then turning marked-up comments into a revised layout
Visiting sites to measure existing spaces, check what has actually been built against the drawings, and snag (list defects for the contractor to fix)
Coordinating with architects, structural and services engineers, lighting designers and contractors - for example checking that a proposed partition doesn't clash with a sprinkler head or a riser

How graduates get in

The standard route is a degree in interior design, interior architecture or spatial design, with a strong portfolio - the portfolio usually matters more than the grade classification
Related design degrees are common and accepted: architecture, product or furniture design, 3D design, set design, even fine art, provided the portfolio shows spatial thinking and technical drawing
Studio placements and summer internships during a degree are the single most reliable way in; many juniors are hired by a studio they interned at, and a sandwich-year placement is a real advantage
Conversion routes exist for graduates from unrelated subjects - a postgraduate diploma or MA in interior design, or an intensive private course in interior design plus CAD - but these need a convincing self-built portfolio to compete

Entering sideways through a related job: CAD technician, FF&E (furniture, fixtures and equipment) assistant, design assistant for a furniture or lighting supplier, or a junior role in a fit-out contractor's design team, then moving into design proper
Freelance and small-scale residential work (friends, family, local projects) is a genuine starting point, particularly outside London, though it rarely provides the technical training a studio does

What employers ask for

A portfolio is the main thing employers assess - typically a small number of projects shown in depth, including plans and technical detail, not just mood boards and pretty renders. Expect to be asked to talk through your process at interview.
A degree or HND in interior design, interior architecture or a related design discipline is usual. Grades are looked at less closely than in, say, finance; a 2:2 with excellent work is often acceptable, but some larger practices do filter on a 2:1.
Demonstrable software ability: AutoCAD is close to universal, SketchUp and Adobe InDesign/Photoshop very common, Revit increasingly asked for in larger commercial and architecture-led practices. Listing software you can't actually use will be exposed quickly.
Some understanding of how buildings go together - construction detailing, fire regulations, Building Regulations Part M (accessibility) and Part B (fire) - matters more than new graduates expect. Many juniors learn this on the job.

There is no legally protected title or compulsory licence for interior designers in the UK. Voluntary professional registration exists through the British Institute of Interior Design, and some designers with architecture degrees pursue architectural registration separately; neither is required to get hired.
A driving licence is often useful for site visits and supplier showrooms outside major cities, though not usually essential in London.

Skills that matter

Technical drawing and setting out

A design only gets built if someone can produce dimensioned plans and details a joiner or contractor can work from without guessing.

3D visualisation and presentation

Clients rarely read plans; the ability to produce a convincing render and a clean presentation deck is often what wins the work.

Materials and product knowledge

Specifying a fabric with the wrong fire rating or a finish with a twelve-week lead time can derail a programme, so designers need to know what's compliant, durable and available.

Cost awareness

Almost every scheme comes back over budget at least once, and the useful designer is the one who can find a cheaper equivalent without wrecking the concept.

Taking and absorbing criticism

Work is reviewed and marked up constantly by seniors and clients, and designs are routinely redone several times - treating that as normal rather than personal is essential.

Coordination and attention to detail

Interiors sit on top of structure, ventilation, sprinklers and electrics, and a drawing that ignores any of those generates expensive problems on site.

Where it leads

Junior / graduate designer or design assistant: producing drawings, sourcing samples, assembling presentations and supporting a project lead. Typically a couple of years, though it varies a lot by studio size.
Interior designer / middleweight: running smaller projects or significant packages of large ones, dealing directly with clients and contractors, and starting to check others' drawings.
Senior designer or project lead / project designer: owning schemes end to end, managing fees and programme, directing juniors. Reaching this stage commonly takes several years but timelines vary widely with studio size and how much responsibility you're given early.
Associate, design director or studio head in a larger practice - more business development, pitching for work and managing people than drawing. Not everyone wants this; plenty of designers stay hands-on by choice.
Alternative directions: specialising (lighting design, FF&E, workplace strategy, healthcare or hospitality interiors), moving client-side into an in-house property or brand team, moving to a contractor or supplier, teaching, or setting up a practice - common in residential interiors, where many designers go independent fairly early.

What people get wrong

“It's mainly about choosing colours, furniture and soft furnishings.”

Most commercial interior design is technical: layouts driven by fire escape distances and accessibility, construction details for walls and joinery, coordination with mechanical and electrical engineers, and long specification documents. Decoration is a comparatively small slice of the week.

“It's the same as the home makeover shows - short projects, dramatic reveals, mostly private houses.”

The bulk of paid UK work is commercial: offices and workplace fit-outs, retail, hotels, restaurants, student accommodation, healthcare and education. Projects can run for a year or more, and much of the design is value-engineered (cut back for cost) before it's built.

“Your personal taste is what you're being paid for.”

You're designing to a client's brand, budget and operational needs, often within a house style set by the studio. Juniors in particular spend a long time executing someone else's concept accurately rather than generating their own.

“An interior design degree is required, and the title is regulated like architecture.”

"Interior designer" is not a protected title in the UK and there's no mandatory registration, so entry is portfolio-led and people arrive from architecture, furniture design and conversion courses. The flip side is that the field is competitive and unpaid or low-paid early experience is unfortunately common.

Where this varies

The job differs a lot by sector and employer type. In an architecture practice or large commercial interiors consultancy the work is technical and Revit-heavy, with formal RIBA-style work stages and long programmes. In a boutique residential or hospitality studio there is far more sourcing, styling, client hand-holding and physical sample work, often with a very small team where a junior does a bit of everything. Fit-out contractors and in-house design teams for retail or hospitality brands work faster, to tighter budgets and with more repetition across multiple sites. Geographically, London and to a lesser extent Manchester, Glasgow, Edinburgh, Bristol and Leeds hold most of the studio jobs; elsewhere the market skews towards smaller residential practices, kitchen and bathroom retailers, and freelance work.
