Keep every model ending
For a replacement washing machine, washer-dryer or dishwasher, keep the full new-product reference rather than just the range name. A slash, suffix or additional product number can distinguish a different fitting or supplied kit.
Fully and semi-integrated differ
For a dishwasher, say whether the controls are hidden at the door edge or remain visible on the front. That distinction helps identify the fitting, but the full model and product instructions are still needed.
Agree old-appliance arrangements
State whether the old appliance is connected, already disconnected or absent. Disconnection, removal and disposal are separate requested tasks whose suitability, access and charges should be agreed before attendance.
Keep delivery and fitting distinct
Tell us whether the replacement product has arrived and is available at the address. Delivery, carrying, unpacking and installation are different tasks, so include the requested work instead of treating them as one automatically included service.
