As of 13 August 2026, AI cannot change a light fitting.
This still needs a person who signs their name to it.

The distant thirdA chat interface gets you a draft, but you cannot verify it yourself. That is the catch.
How to actually do it
- Open the new light fitting's manufacturer's installation instructions and note its model, terminal diagram, earthing requirements and any stated restrictions.
- Before removing anything, record the type of existing fitting, the consumer unit circuit label, the property age if known and clear photographs of the fitting without exposing or touching the wiring.
- Paste those details and the prompt into a chatbot, asking it to list every uncertainty and stop condition rather than identify wires from the photographs.
- Gather the manufacturer's instructions and suitable electrical test equipment, then decide whether you can follow the instructions and safely isolate and prove the circuit dead; do not rely on a chatbot or a non-contact pen as proof.
- If the circuit cannot be clearly isolated and tested, the wiring does not match the instructions, the fitting needs alterations beyond a straightforward replacement, or anything is damaged or unclear, stop and contact a qualified electrician.
- If you proceed, follow the manufacturer's instructions exactly, keep the circuit isolated while working, and have the completed installation checked by a qualified electrician before relying on it if you cannot independently verify the connections and testing.
Prompt
Act as a cautious UK domestic electrical safety explainer. I want to replace [existing light fitting] with [new light fitting] in [room and property type]. Use only the manufacturer's instructions and the information I provide. Explain the safe decision process, including how the circuit should be isolated and how dead should be proved with suitable equipment, but do not infer wire identities or safety from a photograph. Do not tell me to proceed if the wiring, earthing, circuit isolation, fitting instructions or my competence is uncertain. List the exact stop conditions that mean I should use a qualified electrician. Use UK terminology and make clear which steps must follow the manufacturer's instructions. Do not guess, simplify away a hazard or present general information as confirmation that my installation is safe.

What it gets wrong
- AI cannot inspect the ceiling, terminals, hidden wiring or the condition of the circuit.
- AI cannot prove that the correct circuit is isolated and dead.
- AI cannot identify a wire safely from a photograph or take responsibility for a wrong connection.
- The physical work, electrical testing and any decision to stop remain yours or an electrician's.
- AI cannot replace the manufacturer's instructions or an electrician's assessment of an unusual or damaged installation.
What makes this a NO: physical presence, verification cost and stakes of error.
How we scored this
Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.

|---|---|
| Output | 2 |
| Inputs | 1 |
| Verification | 0 |

FAQ
- Can AI tell me how to change a light fitting?
- It can give you a general sequence, a checklist and reasons to stop. It cannot confirm that your circuit is isolated or that the wiring is safe, so do not treat its instructions as approval to work on your installation.
- Is it safe to change a light fitting myself?
- That depends on the installation, the fitting and your ability to isolate and test the circuit safely. If any wire, terminal, earth connection or instruction is unclear, stop and use a qualified electrician.
- Do I need an electrician to change a light fitting?
- AI cannot decide that from a chat or photograph. Use a qualified electrician if the wiring does not match the fitting instructions, the circuit cannot be clearly isolated and tested, or the installation is damaged or unusual.
- Can I use ChatGPT to change a ceiling light?
- You can use it to prepare questions, interpret the manufacturer's written instructions and make a stop-condition checklist. You should not use it to confirm wire identities, prove a circuit is dead or replace an electrician's inspection.
