 Trustindex verifies that the original source of the review is Google. Excellent service from start to finish! He replaced our old pool pump with a new inverter pool pump and did a fantastic job. Very professional, knowledgeable, and efficient throughout the whole process. He explained how the new pump works and made sure everything was running perfectly before leaving. The installation was neat and tidy, and we're very happy with the result. Highly recommend his services to anyone looking for reliable and quality pool equipment installation!

 Trustindex verifies that the original source of the review is Google. I recently purchased a property with a hot tub, so this was my first time arranging a clean and refill. Matt from Unicorn Pools and Hot Tubs Ltd delivered an absolutely spotless service. Everything was done professionally, and he provided all the information I needed as a new hot‑tub owner. I’m extremely happy with the experience and would 100% recommend Matt and his business.

 Trustindex verifies that the original source of the review is Google. I have been using Unicorn Pools and Hot Tubs for two years now, and they never disappoint. They recently came out for a deep clean, and once again, they left our hot tub looking brand new.
The entire process is completely seamless. Scheduling an appointment is incredibly easy, and their pricing is always fair. The team is consistently responsive, highly professional, and deeply knowledgeable about spa chemistry and maintenance. If you want a reliable, top-tier service to keep your hot tub in pristine condition, I cannot recommend them enough!

 Trustindex verifies that the original source of the review is Google. Matt and Charlie have been absolutely brilliant and our pool is now beautifully clean and working wonderfully (after several years of using other contractors). They are extremely knowledgeable and courteous and I would not hesitate to recommend Unicorn.

 Trustindex verifies that the original source of the review is Google. Great service! Matt responded very swiftly to my Checkatrade message asking for someone to replace our pool pump. Amazingly, he quoted and installed a new better pump on the same day as my request, all for a reasonable price. Matt was courteous, efficient and very knowledgeable. Highly recommended and I can see why he consistently gets 5* reviews
