About Constant Hot Water

Our Story

Constant Hot Water was founded over 30 years ago by Ian Constant, who later brought his son Luke into the business at just 18. Together with their dedicated team of engineers, they’ve built a strong reputation and loyal client base through expert heating system installation, including underfloor heating systems across homes, offices, gyms, and schools over the years. Their passion for the work stems from understanding how much difference a well-installed underfloor heating installation can make—transforming comfort levels, improving energy efficiency heating, and helping homeowners save on their heating bills over the long term. The team has continued to grow, with Jake joining as a valued and hardworking addition who’s set to play a key role in the company’s future. At Constant Hot Water, the promise is simple: every system is fitted properly, built to last, and supported with unbeatable aftercare.

Having known and used Ian, Luke, and their team for twenty years on countless projects, I can only praise their professionalism and can-do attitude. Our Plumbing and Heating contracts primarily focus on large, high-end blue-chip properties. Whether it’s an enormous bespoke property or a series of high-end apartments, I trust that from the initial planning, pricing, and site meetings to the heating system installation, completion, and commissioning, I will not encounter any issues with the underfloor heating installation package of the contract, all while ensuring energy efficiency heating.

I have been a customer of Ian and his team for nearly 20 years. They handled the heating system installation in my new build in 2010, and I later invited them to redo the heating in my French house. They are now finishing another new build with me. This underfloor heating installation expert provides an excellent, hassle-free service focused on energy efficiency heating. I’d never use anyone else.
