ELECTRICAL GUIDE · UPDATED 2026-11-05
Before you call: safe observations
Optional, safe notes to help explain a plumbing or electrical problem by phone, without testing equipment or attempting repairs.
Safety before information
These optional notes can help a plumber or electrician understand your request by phone. They are observations, not a diagnosis, a repair checklist or a substitute for inspection. If there is immediate danger, stop here and use the directory’s existing gas, fire, electrical or power-cut emergency guidance first. Do not delay emergency action to collect information, take a photograph, check insurance or compare prices. Give only information you already have or can observe safely.
1. Describe what you already noticed
Say when you first noticed the problem, whether it has happened before, and which rooms, fixtures or appliances you already know are affected. Explain the visible symptom in ordinary language: for example, water appearing below a sink, or a light that stopped working. Report any already-noticed tripping, burn marks or unusual sounds without returning to inspect them. Do not recreate the fault, switch equipment on and off, run water to test a leak or repeatedly reset a protective device. It is fine to say you do not know.
2. Read only an already-visible display
If a display or error code is already visible from your normal, safe position, write down its exact characters. Do not open a boiler casing, fuse box, consumer unit, appliance cover or service panel to find a code or investigate. Do not touch damaged, wet or hot equipment. Do not try wiring, gas adjustments, leak repairs or boiler repressurisation on the basis of this guide. A telephone conversation does not justify unsafe DIY or establish that equipment is safe to use.
3. Take a photograph only if it is safe
An optional photo may help explain what you have already seen, but only from a dry, normal standing position away from the hazard. Do not approach exposed wiring, floodwater, hot surfaces or damaged equipment; do not climb, move an appliance or reach behind it for a better view. Skip the photo whenever you are unsure. Ask the chosen business how it would like to receive it. Keep unrelated people, paperwork, payment details and private access codes out of the image.
4. Use information you already have
Look for the make and model in an existing manual, receipt or saved record rather than pulling out an appliance or removing a cover. If you already know your stop tap’s location, you can tell the plumber. WaterSafe encourages knowing its location before an emergency; this is not an instruction to search an unsafe area or force a stiff tap. Do not attempt gas, electrical or plumbing repairs. Leave identification or access that needs tools, dismantling or exposure to danger to the appropriate professional.
5. Prepare the address and visit questions
Have your postcode, contact number and ordinary access arrangements ready. Mention communication or mobility needs, whether someone you trust will join the call or visit, and any landlord or managing-agent arrangements. Share only what is necessary. Ask who will attend and whether the exact address and job are covered. Request the charging basis in writing, including call-out, diagnosis, minimum labour, parts, VAT and out-of-hours extras. Agree how further work would be authorised; a phone description cannot confirm a final diagnosis, price or arrival time.
- Emergency danger comes first; stop gathering notes if conditions are unsafe.
- Describe what you already observed without live testing or repeated resets.
- Record an already-visible code or use existing make/model paperwork only.
- Photograph only from a dry, normal position; otherwise skip it.
- Give postcode and access needs, then ask for attendance and charging details.
