Where the big price variations come from
- Time of day — a 2am call-out can be 3× a 2pm one.
- Access — top-floor flats, blocked stopcocks and concealed pipework all add time.
- Parts — branded combi-boiler PCBs can be £180+, a generic fill valve under £15.
- Congestion zone & parking — central London plumbers usually pass these on.
- VAT — quoted prices are sometimes ex-VAT. Always check.
Five questions to ask before they arrive
- Is the call-out fixed or hourly, and does the first hour include any work?
- What is the minimum charge if you arrive and the issue is already fixed?
- Are you Gas Safe registered? (Ask for the number for any boiler/gas work.)
- Will you quote a fixed price before starting, or work hourly?
- Do you take card on site and provide a VAT invoice?
