Hi – UK Bee here.
We originally planned our (church) wedding for 3pm, but after further consideration we changed it to 2pm. 3pm would definitely have felt too rushed for us. Starting at 2pm felt good and not many people left the wedding before the end. We actually wish we’d had a few hours longer. So I’d probably vote for 11am for you, esp if you’re a mornings person (which I am NOT!)
From my experience at my own wedding and other UK 11am weddings, what I’ve learned is:
1) If you go for 11am, then either be VERY clear to people what type of food to expect and when, or else served the wedding breakfast at a fairly early time and then the vans later (ie feed people twice). I’ve been to several 11am weddings when I didn’t get fed until about 4pm and by then I was STARVING having had no chance to get lunch. Think carefully about feeding people or when they might eat. We had our wedding at 2pm because we wanted it to be clearly after lunch so people would eat beforehand.
2) It took me longer to get ready than planned. It took me about 3 hours and that was with one hairdresser doing me and one bridesmaid, and me doing my own makeup. We didn’t have as much time for pre-wedding photos of the bridal party as I’d hoped. I’m really not a mornings person so wouldn’t have wanted to get up early enough for an 11am ceremony, but you obviously are a mornings person with a small bridal party so it shouldn’t be a problem.
3) 11am – midnight in the UK shouldn’t be a problem. I’ve been to plenty of weddings that long.
My timeline ran thus:
9.45am took car to the car wash!!! (We were using it as the wedding car)
11am start my hair
12pm start my makeup / bridemaid start hair
1pm put on dress (nb no lunch was scheduled as a friend prepared a grazing fingerfood buffet for us. So we ate on and off all morning).
1.15pm formal photos with the bridal party (we weren’t ready by then – we only had time to take a couple of photos around 1.45pm)
1.57pm walk to the church (down the road)
2.50pm confetti shot / formal shots. This was faster than we expected – we put a list of shots and who we wanted in each one as an insert in the Order of Service to speed things up. It seemed to work well.
3.30pm People went to the reception venue (a 30min drive away). We had some private photos taken first.
4pm-4.45pm cocktails (we were still having private photos so only arrived around 4.30pm)
4.45pm-7pm Dinner (3 courses, 130 people, overran to 7.15pm)
7.15pm-7.30pm speeches (4 speeches, overran to 8pm)
8pm cake cutting then immediately into first dance
8pm-11.45pm dancing. Evening buffet was put out around 8.15pm. We had loads of food left over because of course most of the guests had already just eaten a 3 course dinner. So if you had your dinner earlier in the day due to having an earlier ceremony, more people would probably eat your evening food too.
I hope this helps.
