Milco Di Gaetano
"When we wanted to replace our old boiler Tom came round quickly and showed us the various options. The work was completed ... they were polite and knowledgeable and everything was clean and tidy. The price was very competitive too. We’re so pleased to have found a great company and we’ll definitely be using them for our plumbing in future."
Gordon Loader
"Tom did a great job ... professional and friendly from our initial phone conversation, and explained our options very clearly ... Also stayed late to ensure the job was completed in one day, and took great care to leave everything in our home as he found it. Definitely recommended if you're looking for a trustworthy independent plumber/heating engineer 👍"
