What to prepare
Keep the full appliance identity, a short fault sequence, the complete postcode and any access restrictions together. If somebody else is meeting the engineer, share that same record with them.
What is agreed directly
Engineer visits are Monday to Thursday. Appropriate work, address coverage, charges, appointments and any parts requirement are confirmed individually. No automatic same-day or first-visit outcome is promised.
Make space safely
Remove ordinary clutter where safe. Keep children and pets away from the work area, but leave fitted equipment and service connections undisturbed.
