Start with the type of visit

Firstline’s plumbing fault diagnosis starts from £89 per visit. A straightforward leaking-tap repair starts from £89, while a burst-pipe repair or inaccessible leak may cost more because the scope, access and materials are different.

What can change the price

  • Same-day priority attendance.
  • Evening, weekend or bank-holiday work.
  • Parts and materials required.
  • Restricted access or the need to open and reinstate finishes.
  • Additional faults discovered after diagnosis.

Ask for confirmation before repair work

A professional should explain the likely scope and confirm the price before moving beyond diagnosis into chargeable repair work. If the job changes materially, ask for the revised price before approving it.

Safety first. If there is immediate danger, fire, suspected gas escape or risk to life, leave the area and contact the appropriate emergency service. Online guidance cannot diagnose a property fault.
