Frequently Asked Questions

Emergency plumbers typically charge £80-150 per hour, with additional call-out fees of £60-100. Out-of-hours work (evenings, weekends, bank holidays) often incurs a 50-100% premium on standard rates.
Most minor repairs and replacements don't require building control notification. However, new bathroom installations, system alterations, and any gas work must comply with building regulations. Your plumber should advise on requirements and handle necessary notifications.
Simple repairs like fixing a leaky tap take 1-2 hours. Toilet or sink installations typically require 2-4 hours. Full bathroom installations need 3-5 days, while complete bathroom renovations can take 1-2 weeks depending on complexity.
Absolutely. Always insist on a written quote that details all costs, timelines, and what's included. This protects both you and the tradesperson. For emergency work, get an hourly rate and estimated time before authorizing work to begin.
Look for plumbers who are Gas Safe registered (essential for any gas work), have public liability insurance, and ideally hold relevant NVQ or City & Guilds qualifications. Check online reviews and ask for references from recent customers.
