*In order to ensure speedy receipt, and thereby processing, of cancellations, Anglesey Holidays recommends that the Customer sends written notification of cancellation by email requesting confirmed receipt. The effective date of cancellation is when written notification is received by Anglesey Holidays.

Anglesey Holidays will then use reasonable endeavours to obtain a replacement booking. In the event that Anglesey Holidays is successful in obtaining a replacement booking, we will refund to the Customer the total amount paid by the Customer for the booking less an 5% Booking Fee and less the difference in price between the Customers’ booking and the replacement booking if one is made.

For example:  A £1000 booking, fully paid, cancelled and relet for £900, means that the original Customer will be refunded as follows, £1000 – 5% booking fee equals £950, – £100 rebooking shortfall, = Refund of £850.

i/ It is the responsibility of the Customer to acquire suitable travel insurance for themselves and their party to cover the booking. Anglesey Holidays strongly recommends that the Customer acquires suitable insurance to cover circumstances beyond the Customers’ control such as, but not limited to, jury duty, incarceration, change in personal or work circumstances, military service, illness – including Covid and shielding, family emergencies and travel delays.

Covid is also now a known risk and it is possible for you to insure your holiday against it. This can include the customer or any of the party having Covid, the customer or any of the party having to isolate or quarantine, or you wishing to shield any Members of the party.

There are several options which include cover for Covid related cancellations available from organisations like Trailfinders: https://www.trailfinders.com/insurance#/step1 or https://www.coverwise.co.uk/Travel-Insurance/corona-virus.aspx or www.gocompare.com or the Post Office.
