What changes an Ariston repair bill
- Brand tier — High-volume Italian brand with a large UK installed base and a deep independent spares channel, but its control boards are priced clearly above the mainstream band: on the Direct Heating Spares Ariston PCB page (prices incl VAT), the boards comparable with the reference — every listed PCB that is neither display nor clip-in — run £75.60, £183.60, £201.60, £298.80, £319.20, £345.60, £360.00, £361.20 and £438.00, a £319.20 median against the £240.00 midpoint of the £218.40–£261.60 reference band (1.33x). On this guide's board-ratio mapping (Vaillant 1.10x → 1.2, Viessmann 1.52x → 1.25) that supports a 1.2 parts factor.
- Parts vs labour — the brand and tier shift the parts price; labour tracks your area's wage index, not the brand.
- The specific fault — a sensor, seal, or valve is far cheaper than a compressor, motor, or control board.
- DIY vs professional — Some Ariston faults (filters, seals, hoses) are DIY-feasible for confident owners; sealed-system and control-board work is a professional job.
