Good to know
What if I need to cancel or move my clean?
Free up to 48 hours before. Between 24 and 48 hours before, it’s 25% of the booking. Under 24 hours, or if your cleaner is turned away or locked out, it’s 50%. The first late cancellation is waived once per customer and address. Going away? Tell us more than 48 hours before and skipped visits are free. Your 14-day right to cancel still applies (see term 9). Cancellation terms.
If we cancel with under 24 hours’ notice, your next clean is £20 off.
When do I pay?
We’ll send you a secure card link to confirm your booking, and your card is charged after the clean. If a card payment fails, we’ll email you a link to pay within 7 days. We don’t accept cash paid to cleaners.
How quickly will I hear back?
We aim to send a written quote within 24 hours. Offices get a free site visit, and serviced apartments a walk-through of a sample unit.
