“

Had a fault on our hot tub. Called Castle hot tubs. Received polite response and quick booking. Engineer that came was efficient and polite and got the repair done in a timely manner. Amazing service .

“

Castle Hot tubs are a great local company. Helpful, and provide a first class repair service at short notice. They have lovely staff. Paul came to repair our hot tub. He was friendly and very efficient. I wouldn’t hesitate to recommend them.

“

As a holiday cottage owner, when we have issues with our swim spa we really need swift, efficient support. Our 6,000 litre spa developed a serious leak and our worry was palpable as our next guests were due in. I messaged Castle Hot Tubs during 'out of hours' with the hope my plight would be answered in the morning, but I immediately received a reply that a service technician (Paul) would be with us first thing in the morning. The next morning Paul arrival and the repair was very swiftly undertaken and our spa was back up and running again very quickly indeed. I can't praise this service enough, it's so reassuring to have Castle Hot Tubs looking after us. Thank you so much.

“

Paul was cheerful, helpful and knowledgeable about our hot tub. Explained everything and answered all our questions, and friendly. A great experience having Paul at our property. He went above and beyond to help us with everything.So happy with everything.

“

We were recommended to Castle Hot Tubs after acquiring a hot tub on moving house. They are always friendly, helpful and efficient. Paul serviced the tub and has returned a couple of times since to carry out a spa refresh and do any necessary adjustments, all done with a polite and friendly manner. He patiently answers my questions on water treatments etc (probably the same ones every time!) and offers friendly advice if asked. Can highly recommend.

“

Friendly and knowledgeable. Answered all my questions and was efficient, clean and tidy. Always on time adaptable and informative about date and time of service. Recommend this company and their staff.
