Scope of Works
• Visual inspection of indoor and outdoor units to assess condition and mounting
• check electrical isolator, fuses and basic wiring condition (no invasive electrical work unless quoted)
• measure airflow, temperature split and basic performance under run conditions
• check refrigerant pressures and compressor operation where F‑gas certified engineer is present
• inspect condensate drain and pump plus look for signs of leaks or mould contamination
• provide a written assessment with photos, test readings and recommended remedial work or replacement options
Typical Cost
Charge Type | Low £ | High £ | Notes |
|---|---|---|---|
Call-out / Minimum | £90 | £150 | First 30–60 min on site |
Labour per hour | £50 | £90 | Includes diagnostic testing and basic measurements |

Time on Site
Most assessments take 1–2 hours on site for a single split system; longer if there are multiple indoor units, restricted access to the outdoor unit or the engineer needs to trace a refrigerant leak or dig out service history
Questions to Ask Your Tradie
• are you f‑gas certified and insured to work on my system
• will you provide a written report with photos and measured readings after the visit
• what does your call‑out fee cover and how do you charge for additional labour or testing
• do you need roof or loft access and can you provide safe working‑at‑height equipment if required
• will checks for refrigerant levels or leaks incur extra charges and how are any refrigerants handled/disposed
• can you give a ballpark cost for common follow‑up repairs so I can budget
How to Avoid Surprises
• clear space around indoor and outdoor units so the engineer can work safely
• leave access to the consumer unit, isolator and thermostat and bring any previous service records
• reserve close parking or advise of access restrictions so engineers can bring ladders/test kit
• secure pets and inform the engineer of restricted areas or landlord/managing‑agent rules
• advise the engineer beforehand of known issues such as noises, recent leaks or intermittent faults
