Start with the pattern
Tell us how long the car was parked, how often it is used, whether the battery is new and whether the problem began after another repair or an accessory was fitted. A dashcam, stereo or tracker is useful context, not proof of the cause.
Separate three different questions
Can the battery hold an appropriate charge? Is the charging system working as it should? Is something using excessive power while the car is parked? The test sequence depends on the symptom and the vehicle; one voltage reading does not answer every question.
Choose the right visit
A reported starting or charging fault normally starts with the £89 diagnostic visit, up to 60 minutes. A repeated parked drain starts from £129 for up to 90 minutes of initial investigation. Some intermittent drains need monitoring or a return visit, agreed in advance.
Send useful details
Send the registration, postcode, battery age if known, and how quickly the problem returns. A photo of the warning message may help. Tell us whether the car currently starts and moves so we can assess the visit.
