To expect redress from wedding venue?

Decide what you want and push very hard for that.

Whatever the contract says, they should have told you when they took the booking for the filming and given you the opportunity to cancel then. Very bad customer service not to do so. You don't have to be horrid about it or worry about being a bridezilla but decide on either a figure or - more likely - a compensating extra or workaround and do not stop banging on about that until you get it. Make it easy for them to appease you by giving them something specific.

That would be shit

They will be hoping you don’t kick up a fuss - so if you push back quite hard to them - and ask if this filming booking was made before or after your wedding booking - i think they might try to be a bit more helpful.

Would they allow you to return after the event to do a photo shoot as a compromise?

The wording says they may not have 'exclusive' use of the grounds. Not that they may have limited use of the grounds /that the grounds may not be available on the day of the wedding.

Very different things.

Non exclusive means they still have use of the grounds.

No - it said "exclusive" use. Not NO use.

I'm not sure. If the grounds are a verified main aspect of a location the offering a different one may not be considered acceptable

If depends how much the location is why people book.

That's why you often have redress if a hotel that is known and promoted for its view and tranquility has building works going on.

OP perhaps they can get filming to schedule your shoot in or perhaps if it is a university different colleges, they may be able to find an alternative college that has beautiful grounds

This is a good idea. Are they providing any catering? Maybe ask for a gesture of good will such as them covering the first drink? Are there other areas that might not be free access but would be good for photos. Could you request access given the circumstances. I think you might have more luck with this kind of thing than a straight cash reduction.

What’s the definitions of “grounds” in the contract? What does it say about reserving the right to prohibit access to certain areas of the grounds?

I agree with this point. Go back and carefully read the contract- if it says you have use of the grounds (exclusive use or not) then they have agreed to you having access. Do you have any legal friends who could take a look at the wording for you?

Exclusive use of the grounds

They have use of some of the grounds, other parts are being used by others

So not exclusive

Covered by T&Cs

I get it’s disappointing and why you’d want some redress but honestly I wouldn’t focus so much on photos/ being insta worthy. It’s a day you’ll remember forever anyway.

Strong case for mis-selling and misrepresentation.
You were not informed at time of booking that any area would be off limits completely.
The area that is on all their advertising, and led you to make the booking, is now, through their own actions, no longer available. As you were the prior booking, would have thought you should have had priority.
As I doubt you would be able to find an alternative venue in such a short space of time you are going to have to fight to (hopefully) prevent your special day being ruined.
Whilst it is far from ideal, I would go in hard with unless they make that area accessible to you for a set period of time, (with a financial compensation for the unreasonable stress etc) you will be going to the small claims court to seek a full refund.
Also name and shame.
I am so sorry that you are facing this when you should be enjoying your last few weeks of planning!

Just to be clear, in your booking contract does it say you have booked the chapel AND access to the grounds, with the caveat that grounds won’t be for your exclusive use so others may be there. Because if they’ve got a contract with you to use the grounds then keep quoting it back at them and perhaps give a specific time of the day when you will take those particular photos so they can arrange with the TV production?

I think the phrase ‘not Garunteed exclusive use’ implies that the non exclusive use of the grounds IS included in your booking

I thought the same about Harry Potter but my mind went to Glasgow Uni.

Wow, that's very catty!!

What a nasty comment. It's quite reasonable to be inspired by something and use that to inform your theme, or to pick a particular venue as it chimes with something of interest, importance or symbolism for you.

I get why you are so disappointed - it's very close to the date and part of the day you have been imagining has suddenly been taken away

I would focus on the phrase 'not guaranteed exclusive use'

That is very different from not getting any access at all

Will you have any access or us filming covering the whole area for the whole time?

You still want use, even if it's not exclusive!

I think you could have a go at it, but not sure you will get anywhere. I can understand why you are annoyed though.

Afraid I'm not sure there's much you can do legally! Could ask them whether you'd be allowed even a 15 min slot to pop in & get one particular shot, or be allowed back another time to get the photos but in your shoes I'd probably let these photos go & enjoy your wonderful day!! X

I can understand entirely, that you are very disappointed that the area for the venue is now off-limits due to filming going on, however since the wording of the booking contract says exclusive use can't be guaranteed, I think they haven't broken any laws here, although you could try the argument again, that you already mentioned, that saying exclusivity isn't guaranteed is not the same thing as saying you can't get access and how will they make this up to you and see what happens

I think it is unlikely that at the time they took your booking last year they would know about the filming taking place to be honest. Members of the Public visit a place that I worked at and filming for something well known took place a year or 2 or 3 ago there. But dates were often vague and only confirmed much nearer the time. Dates had to be changed on occasion too, very last minute.

That doesn't help you much now though, I do understand. I don't think there is much you can do now, though, except come to terms with your disappointment before the wedding and just enjoy the day?

This is sensible. I understand why you’re disappointed OP but I’m not sure legally you have much case for redress. If you come with a concrete suggestion like these they may do it out of goodwill.

Nobody is filming the wedding. They’re filming something else which is preventing OP getting access to the part of the grounds she wanted for photos.
