He's surprised you!
How wonderful. He suddenly turned to you and said those immortal words "Will you marry me" The answer was of course "Yes" and then you thought when?
You might not wish to wait until every day life returns to normal. You may wish to have your ceremony on Christmas Day or Boxing Day. A Celebrant led wedding is possible on any day of the week, Sundays, Bank Holidays and at any time of the day.
Chat to a Celebrant and see what they can offer. They are very flexible and willing to assist in any way possible. Why wait.....
