Aipedia: Interior designers
AI lighting tools can generate attractive schemes and circuit layouts, but they do not make an interior designer competent to design electrical installations. BIID clause 1(b)(i) limits members to work they are qualified for, and safety defects in lighting can cause injury and fire.
Part of: AI in Interior designers
In short
Interior designers may use AI to plan lighting schemes, position fittings and sockets, and suggest circuits and controls. The design intent is usually the designer's role; the electrical design and installation belong to a competent electrician or engineer. AI tools blur that line by producing technical-looking layouts. BIID Code clauses 1(b)(i), 4(a) and 4(c) require competence and care, and CDM 2015 and Part 2A designer duties apply on building work. Keep lighting drawings as design intent, coordinate with the electrician, and do not issue AI electrical details as instructions.
AI tools can suggest lighting layers for a room, place downlights and wall lights on a plan, recommend colour temperatures, estimate light levels and even propose circuits and switching. Some produce drawings that look like an electrician's layout. For designers, this is a quick way to present a lighting concept. The problem arises when the drawing goes to site and is treated as an electrical design.
Electrical installation must be designed and installed by competent people in line with the relevant regulations. See the BIID Code and AI guide.
Illustrative scenario. A designer uses an AI tool to lay out bathroom lighting and issues the drawing to the client's builder. The tool places a pendant and a standard socket too close to the bath, and recessed downlights through a ceiling that forms fire separation to a flat above, with no fire-rated fittings noted. The builder follows the drawing. An electrician later refuses to certify the work, parts must be removed, and the client claims the cost from the designer.
Other risks are overloaded circuits, fittings unsuitable for their location, heat from fittings near insulation or fabrics, and control systems specified without checking compatibility.
A clear split of responsibilities avoids most problems. The designer sets the lighting intent: the look, layers, positions and fittings. The electrician or electrical engineer designs the installation, confirms suitability for the location, and certifies the work. Mark AI-assisted lighting plans "design intent only, subject to electrical design", and ask the electrician to confirm positions and fittings in writing before installation. Under BIID 7(d) and 7(e), check that subcontractors are insured and advise clients to check the insurance of contractors they appoint. The AI space planning guide covers related layout issues.
A claim about a negligent lighting scheme within your declared activities is commonly within interior designers' PI, subject to the terms. Cover is less certain where a designer has strayed into electrical engineering design that was not declared, and some policies exclude bodily injury or property damage, which may need public liability insurance. The specification risk guide explains how fittings errors arise. See also does PI cover AI and IP claims.
Lighting in commercial interiors carries more requirements than in homes. Restaurants, shops, offices and hotels may need emergency lighting, specific light levels for tasks, glare control and lighting that supports accessible wayfinding. Healthcare and care settings have their own expectations. General AI tools may not account for these points. Where emergency lighting or specialist requirements apply, a qualified lighting or electrical designer should lead, with the interior designer setting the decorative intent. Recording that split in your agreement under BIID 3(b)(i), which covers project parties and their responsibilities, makes your role clear if something later goes wrong.
How Apex helps: Apex arranges PI for interior designers. A broker can check that your declared activities match your lighting work and how the policy treats AI-assisted layouts. See PI insurance for interior designers.
Designers commonly set lighting intent and fitting positions. Designing the electrical installation itself requires the relevant competence, and BIID clause 1(b)(i) limits members to work they are qualified for.
Only as design intent, clearly labelled, and only after a competent electrician has confirmed positions, fittings and circuits. Builders may otherwise treat the drawing as an installation instruction.
It depends. PI may cover a claim alleging negligent specification, but bodily injury and property damage are often dealt with under public liability insurance. Check both policies and how they interact.
Set out whether your service covers decorative lighting intent only, who will carry out electrical design and installation, and who certifies the work. BIID clause 3(b)(i) requires the agreement to cover project parties and their responsibilities.
