AI in interior design: rules, risks and professional indemnity

Aipedia, by the Apex broking team · Last reviewed 2026-10-27

No regulator has written AI rules for interior designers, so the BIID Code of Conduct, building safety law and ordinary negligence principles decide what is acceptable. That matters because the designer, not the software, owes the client a duty of care and faces any claim.

Part of: AI in Interior designers

In short

Interior designers may use AI for moodboards, layouts, product sourcing, renders, budgets and client admin. There is no statutory regulator, and BIID has published no AI guidance. Its Code of Conduct dated 1 April 2026 does not mention AI but still governs every AI-assisted task: truthful marketing, competence, written agreements, accurate supplier information and confidentiality. CDM 2015 and Building Regulations Part 2A designer duties apply on fit-outs. The Government's March 2026 copyright report proposes ending protection for purely computer-generated works. PI is not compulsory by law, but BIID requires Registered Interior Designers to hold it.

How interior designers use AI

We found no published survey of AI use among UK interior designers. The nearest evidence comes from architecture: the RIBA AI Report 2026 found that about 56% of AI-using architecture practices use it for early-stage visualisation, and 76% agree AI increases the risk of their work being imitated. Interior design studios have access to the same kinds of tools, and the tasks they apply them to are broadly predictable:

moodboards, concept images and style options at the start of a project;
space planning and furniture layouts from a floor plan or room photo;
product sourcing, specification schedules and procurement trackers;
photoreal renders, virtual staging and portfolio imagery;
budgets and cost plans for refurbishments;
lighting and electrical layouts;
client questionnaires, chatbots, proposals and contract drafting.

Each of these sits inside work that the designer is paid to get right. The software does not take on any of the designer's duties to the client, to suppliers or under building safety law.

Who sets the rules

"Interior designer" is not a protected title and there is no statutory regulator. The British Institute of Interior Design (BIID) is the professional body. Its Code of Conduct, in a version dated 1 April 2026, applies to Registered Interior Designers and Associate members.

As at October 2026, BIID has no AI-specific guidance or Code provision. The 2026 Code does not mention AI; the word "technologies" appears only in clause 14(a)(iv), about sustainable technologies, and the Code guidance notes contain no AI note. The existing clauses still apply to AI-assisted work. The ones that matter most are:

1(a)(i) to (ii) truthful, factual statements and honesty about expertise and resources, and 1(a)(iv) avoiding copyright breaches;
1(b)(i) taking on only work you are qualified and competent to do;
3(a) to (c) a written agreement covering scope, fees, IP ownership and design rights (3(b)(vi)) and insurance, with no unfair terms for consumers;
4(a) reasonable skill and care, 4(c) competence, and 4(d) accurate information to consultants and suppliers;
5 data protection and confidentiality, including reviewing processes and acting on breaches;
8(e) not knowingly copying another designer's work.

The BIID Code and AI guide maps each clause onto AI use.

Building safety duties on fit-outs

When an interior designer's work involves construction, statutory designer duties apply whatever tool produced the drawing. Regulation 9 of the CDM Regulations 2015 requires designers to eliminate, reduce or control foreseeable health and safety risks so far as reasonably practicable. In England, Part 2A of the Building Regulations 2010 requires anyone carrying out design work to have the necessary competence (reg 11F) and, under reg 11K, to take reasonable steps so the design would comply with the relevant requirements if built. Fit-outs that move walls, doors or lighting can affect escape routes and fire safety. AI layouts and lighting plans need checking against those duties, as the specification risk guide explains.

Copyright and imitation

The Government's Report on Copyright and Artificial Intelligence (18 March 2026) proposes removing copyright protection for computer-generated works with no human author under section 9(3) of the Copyright, Designs and Patents Act 1988. AI-assisted works, where a designer's own creative choices are present, would remain protected. The report drops a broad text and data mining exception with opt-out as the preferred option, and makes no immediate change to the law.

In Getty Images v Stability AI [2025] EWHC 2863 (Ch), the High Court rejected secondary copyright infringement claims because the model was not an "infringing copy", while finding limited trade mark infringement for watermarks in early outputs. That decision does not make an output safe to use: an image that closely echoes a recognisable designer's or brand's work can still prompt a complaint, and BIID clause 8(e) applies.

The main risks

Expectation gaps: AI concepts and renders that show furniture, finishes or effects nobody can supply or build.
Specification errors: AI-suggested products with the wrong fire rating, durability class or availability.
Safety defects: layouts and lighting plans that compromise escape routes, access or electrical safety.
Budget reliance: AI cost estimates that understate the real price of a refurbishment.
IP disputes: outputs that resemble another designer's work, or unclear ownership of AI-assisted designs.
Confidentiality: photos and plans of private homes uploaded to AI tools without proper controls.

Professional indemnity and AI

PI is not compulsory by statute for interior designers. BIID Code clause 7 requires insurance appropriate to the nature and size of the business, adequate for claims from professional activities and covering the practice and its employees, and asks members to check subcontractors are insured. BIID guidance says it requires Registered Interior Designers to hold PI and public liability insurance. No minimum limit is set.

BIID and insurers have published nothing specific on AI and PI. In general, interior designers' PI responds to claims alleging negligent design or advice whatever tool was involved, subject to the policy terms. The questions to check are whether AI is mentioned at all (the silent AI problem), how IP infringement is treated, and whether your proposal form answers describe your real workflows.

First steps for a studio

List the AI tools in use and what each is used for.
Decide which outputs are illustrative and which the client may rely on, and say so in writing.
Check every specification, layout and budget against real sources before it leaves the studio.
Keep client photos and plans out of tools that retain or train on uploads unless the client agrees.
Tell your broker how you use AI at renewal, and read the policy for AI and IP wording. The designers' PI guide covers the wider basics.

Frequently asked

Does BIID allow interior designers to use AI?

BIID has published no AI-specific rule or guidance, so nothing in the Code of Conduct prohibits AI. Members must still meet every existing clause when they use it, including truthful statements, competence, reasonable skill and care, accurate supplier information, confidentiality and not copying other designers' work.

Is professional indemnity insurance compulsory for interior designers?

Not by law. BIID Code clause 7 requires appropriate and adequate insurance, and BIID guidance says Registered Interior Designers must hold PI and public liability insurance. Clients and commercial contracts often require PI too, sometimes with a stated limit.

Will my PI cover a claim caused by an AI tool?

Usually, if the claim alleges negligent design or advice in your professional work and the policy has no relevant exclusion. Cover depends on the wording, any IP or technology exclusions, and whether you disclosed how you use AI when you bought the policy.

Can I own the copyright in an AI-generated design?

Where your own creative choices shape the design, it is likely to be protected as an AI-assisted work. The Government proposed in March 2026 to remove protection for purely computer-generated works under CDPA section 9(3), though the law has not yet changed.
