Can I have a normal pendant in my bathroom?

Only outside the zones (outside 0.6m horizontal from bath/shower edge) and ceiling height 2.25m+ — typical free-standing or roll-top bath with pendant centred above is in Zone 1 + requires IPX4. Practical: most modern bathrooms with bath against wall have pendant zone outside Zone 1 if positioned thoughtfully. Walk-in shower spreads Zone 1 over wider footprint — pendant rarely fits outside zones.

Are LED strips in bathroom OK?

Yes — must be IP65 silicone-sealed in Zone 1/2; driver IP-rated to its zone or located outside zones. Common: under-vanity wash light, behind mirror, cove + coffer ambient. 12V SELV preferred for Zone 1 strip (no shock risk). Specify warm white (2700–3000K) for relaxation; tunable white (1800K–6500K) for circadian premium spec.

Do I need an electrician for a bathroom light swap?

Like-for-like replacement (same fitting type, same IP rating, same circuit): notifiable per Part P; competent person self-certifies. New install / circuit alteration / addition: definitely notifiable + competent person. DIY: prohibited in bathrooms post-2005 Part P. Insurance + sale: certificate required as evidence of compliant work.

What IP Rating Do I Need for London Bathroom Lighting?

London bathroom lighting IP ratings per BS 7671 Section 701: Zone 0 (inside bath/shower) IPX7; Zone 1 (above bath/shower to 2.25m) IPX4 minimum; Zone 2 (0.6m horizontal around Zone 1) IPX4; outside zones standard IPX0/IP20 acceptable. 12V SELV preferred Zone 0/1; 240V via RCD protection. Class II (double-insulated) preferred. Isolator switch outside bathroom mandatory (pull-cord inside acceptable for lights only). Supplementary bonding to all metal pipes/fixtures.

Zone definitions BS 7671 Section 701

Zone 0: interior of bath or shower — fitting must be SELV 12V max + IPX7 (immersion-proof) — typically only LED tape (silicon-sealed) or specialist shower-head light. Zone 1: above bath or shower up to 2.25m above floor — IPX4 (splash-proof) minimum + 230V acceptable if RCD-protected — typical IP65 LED downlight (Aurora, Collingwood, JCC) or IPX4 sealed pendant. Zone 2: 0.6m horizontally around Zone 1 (typical above-vanity zone, walk-in shower wider zones) — IPX4 + 230V via RCD — typical mirror light + above-vanity downlight + wall sconce. Outside zones: standard IPX0/IP20 + 230V — typical ceiling pendant or standard downlight outside Zone 2 wash. All fittings + sockets in bathroom (any zone): supplementary bonding to all extraneous metalwork (pipes, towel rail, bath frame); 30mA RCD protection on all circuits; isolator (double-pole) outside bathroom or accessible from outside (pull-cord inside acceptable for lighting circuit alone — not for power).

Fittings + practical specification

Above shower / above bath (Zone 1): IP65 LED downlight — Collingwood H2 Lite IP65, Aurora MPro AU IP65, JCC FireGuard IP65 — £25–£85 per fitting. Fire-rated (flat ceiling between flats): IP65 + 60-min fire — Aurora AU EFD IP65 60min Fire — £45–£125 per fitting. Above vanity (Zone 2): IP44 mirror light or IP44 wall sconce + IP44 downlight — Astro Padova, Original BTC Hector, Davey Lighting Tilbury. LED mirror with integrated light + demister + dimmer (Bathstore, Crosswater, Mirror & Light) £350–£950 supplied — IP44 typical. Ceiling pendant in larger bathroom outside Zone 2: standard IP20 acceptable but consider moisture exposure — IP44 sealed pendant lasts longer. LED strip in mirror or cove: IP65 silicone-sealed strip + IP65 driver inside bathroom or IP20 driver outside (preferred). Underfloor heating mat: low-voltage 12V SELV mat + isolator. Towel rail: thermostatic radiator valve (TRV) electric or wet-plumbed. Extract fan: 95–150 m³/h continuous extract or boost timer; humidistat + timer combination preferred — Vent-Axia Sentinel, Manrose Quiet, Nuaire Drimaster Eco.

Process + certification

Bathroom electrical work classified as 'special location' under Part P — Building Control notifiable; competent person (NICEIC/NAPIT bathroom-installation registered) self-certifies. Non-registered: building notice + inspection required. RCD 30mA protection mandatory for all bathroom circuits (combined RCBO preferred — per circuit). Supplementary bonding test: continuity between all metalwork (pipes, towel rail, bath frame, shower frame) — measured + recorded on Minor Works or full EIC. Common defects on existing bathrooms: extract fan ducted to loft void (not external) = condensation + mould; ceiling downlight IP20 in shower zone (failing IP44 minimum) = corrosion + electrocution risk; supplementary bonding missing (older properties) — EICR Code 2 finding. Renovation opportunity: bring full bathroom to current standard at minor incremental cost vs separate retrofit.
