We also take credit and debit cards, adding Barclays Bank's charge (its "interchange fee") of 2.6%. On a £40 fee, for example, the total charge will be £41.
Please note that on the Sunnah Days we may be quite busy so it is advisable for you to book early to avoid disappointment.
Also please note that because we advise fasting for at least 3 hours before the session, some people like to book appointments early in the day, often before going to work. So we suggest you book well in advance to secure early-in-the-day slots.
