Diagnosis before a repair decision
The £92.50 covers up to 45 minutes to investigate the fault. We aim to get your boiler working during the visit where possible. The fee is for the diagnostic visit and is payable regardless of the outcome. Any further repair work is agreed separately. What happens at the visit.
Repair quotations. Where a repair is suitable and clearly defined, we can give you a fixed-price quotation. If we can carry out the next stage, we explain the scope and agree the price with you before any work goes ahead. A diagnostic visit is the most reliable way to find out what is needed. If you would like to try first without a visit, report the fault and we will message you to ask for photos and a short video of the boiler, its display and the model label. Where those are enough, we may be able to give you a repair quotation without a visit, including a fixed price for a suitable, clearly defined repair; otherwise the diagnostic visit comes first. The diagnostic visit charge is separate from any repair quotation. Heating People reviews every price before it is sent, and your booking is confirmed once payment has been received.
A displayed code is useful evidence, not a confirmed failed component. The engineer assesses the boiler and connected heating system before recommending the next step.
Photos and video that help us price your repair
After you report the fault, we message you to ask for photos and a short video. Having these ready saves time:
- The whole boiler and the space around it.
- The display, showing any code or message. A short video is best if it flashes or changes.
- The data label with the model name and serial number.
- The pressure gauge, and any leak, drip or staining you can see.
- For banging, whistling or kettling, a short video with sound.
Photograph only what is visible. Do not remove the casing or touch the boiler. If you smell gas, do not use the form: call the National Gas Emergency Service on 0800 111 999.
Check guarantee cover first
If the boiler may still be covered by a manufacturer guarantee or maintenance plan, check with the provider before authorising a paid independent repair. Confirm whether they need to arrange the visit and whether third-party work could affect a claim.
Ariston standard warranty guidance calls for professional servicing every 12 months and registration within 30 days of commissioning. Warranty length and eligibility depend on the product and registration arrangements. Check the terms that apply to your installation rather than assuming a current promotion applies.
Repair, parts or replacement?
Repair options depend on the findings, the condition of the boiler and the availability of suitable parts. If we can carry out the next stage, we explain the scope and agree any additional cost with you before proceeding; if the work is outside our scope or we don’t have availability, we may recommend contacting the manufacturer or another suitable specialist. A diagnostic booking does not guarantee same-day completion or that an older appliance can be repaired.
Ariston models we repair and service
We work on Ariston gas boilers, including the ranges below. This is a guide, not a complete list: if your boiler is not shown, send the model name and we will confirm before you book.
Current ranges: Alteas ONE Net, Genus ONE Net, Clas ONE Net, Clas ONE R, Clas System ONE, E-Combi ONE, E-System ONE.
Older ranges we still see: Genus HE, Clas HE, E-System evo.
The model name is usually on the front of the boiler or on its data label. A clear photo of the label helps us prepare. Range names were compiled from manufacturer and trade sources on 6 November 2026; names and availability change, and parts for older models cannot be guaranteed.
Details that help us prepare
Confirm that the appliance is an Ariston gas boiler and send its full model description. Ariston also supplies other types of heating and hot water equipment, so a brand name alone is not enough to select the visit. Include any fault display and the last service record.
Add the full property postcode, photos of the boiler and controls, any service paperwork and safe access arrangements. Photograph only what is visible without removing the casing. Tell us about parking, key collection or managed-building access.
Booking & arrival
Heating People reviews the job, location and pricing before issuing a quote or invoice for advance payment. Once you have paid, your booking is confirmed.
A two-hour arrival window can be confirmed on the day. For a tenanted property, provide the landlord or agent authorisation and payment contact separately from the occupier access details.
