Short answer: Cost depends on the service type, diagnosis, model and parts, connected fixtures, pipe route, access, electrical work, drainage alterations, location and whether earlier installation defects must be corrected. A useful quote needs more than a postcode.
Situation and next step
| Situation | Sensible next step |
|---|---|
| Repair enquiry | Provide symptoms, model, photos, fault history and access details. |
| Replacement enquiry | List fixtures and include the existing unit and pipe route. |
| New installation | Provide a route sketch, lift/run measurements and intended drainage connection. |
Why headline prices mislead
A call-out, diagnosed repair, appliance-only replacement and corrected installation are different scopes. Quotes should state what is included, excluded and subject to inspection.
Information that improves a quote
Clear model-label photos, a short symptom history, access photos and measured route details reduce uncertainty. Never include personal contact details in public reviews or analytics.
Compare like with like
Check whether parts, labour, pipework, electrical work, testing, waste removal and any return visit are included. Do not compare totals without scope.
