I recently had my hot tub serviced by Heavenly Hot Tubs, and I couldn’t be more impressed with the experience. From start to finish, the family team were professional, punctual, and incredibly knowledgeable. My hot tub is older and I didn’t buy it from Heavenly, but that didn’t stop them from being super helpful. They managed to track down a new lid and a heat pump to keep it running efficiently. I was really impressed with the service and highly recommend them to anyone.Posted on Jayne SangsterTrustindex verifies that the original source of the review is Google. Absolutely brilliant service from a family run company. I’m delighted with my hot tub and follow up service. Highly recommendPosted on Conn FultonTrustindex verifies that the original source of the review is Google. Very helpful and informative from first going to view the hot tubs to delivery/installation. We originally chose a wood fired option but we had issues with 3rd party approvals. Heather & Jon were very helpful in facilitating our switch to a Fisher 5S model instead. We were really keen on getting delivery asap, we ended up getting the delivery/install in a few days from order due to availability. We were very happy with service received and would definitely use again.Posted on Reaper 26Trustindex verifies that the original source of the review is Google. I had a hot tub delivered on the 21/10 From start to finish everything was first class service. From point of contact to delivery to instal. I have also contacted this company with advise on things and their after care is amazing. It’s so hard to find a great company with excellent aftercare. I can highly recommend.Posted on Rodney MainTrustindex verifies that the original source of the review is Google. Bought a Hottub from Heavenly hottubs… Bought a Hottub from Heavenly hottubs last September( 2024), I found the company could not do enough for us appointments were kept and after several months of use we decided to get a heatpump installed, again everything was explained to me by Jon the owner, he was very prompt and efficient. Today was the yearly service that we opted in for, Eillie ( apologies if I've spelt it wrong ) carried out the service, she was very thorough and cleaned and maintained the hottub filters, pipes, internals, and all external fittings. This company is a family run business and are very customer focused, from my experience in any dealings with them I only have praise for their service and their determination to customer satisfaction
