Things our customers say

Egham
Living so far away from my sister, me in South Africa and my sister in the UK, there is nothing better to do than to send flowers for happy or not so happy occasions. When sending with your organisation it turned both into happy occasions, for the recipient and sender. What a brilliant service. Thank you and well done. I will definitely continue to use your service.
King's Lynn
I have not seen the flowers, they were for my sister who had just had major surgery and lives 250 miles away. Her daughter rang me to say they were lovely. I had ordered a vase which was broken on arrival but the refund for it was prompt. I also had a text to say they were on their way at 08.30 but they didn't arrive until late afternoon, so were out of water for quite some time.
Sutton Coldfield
The order was placed on Monday 28/10, I had a text on Tuesday morning to say the flowers had been dispatched, a further text to say they had been delivered at 2:00pm and a phone call from my sister in law at 2:05 to say thankyou for the beautiful bouquet Still going strong today 15/11
Preston
the ordering process was very easy and straight forward for next day delivery- I did get a bit worried when they hadn’t arrived by 4-30 but then my sister called to say she was delighted to receive the flowers just after 5pm and after 2 1/2 weeks on they are still lasting so very pleased.
Saxmundham
Excellent service, from ordering online from my home in Brittany, France to prompt delivery to my sister in Peasenhall, Suffolk. I shall use SerenataFlowers again.Better than ordering by Interflora at the florist in Huelgoat----- a week to deliver was quoted !
Ulceby
I have sent my sister and sister in law flowers for their birthdays and they both reported back to me that they were lovely they arrived in bud which made them last longer, they arrived on the right days, so I was pleased and would use this site again.
