"I’ve had two stoves now from Ludlow stoves. Gregg and Corra, have been very professional in every aspect of our dealings. A wealth of knowledge about different devices and their applications. And when I had a faulty installation done on one of my cookers (not by Ludlow Stoves) - they came to my rescue, came and told me what the problems were, and then re-fitted the whole installation themselves. You are in very safe hands in a field where there seem to be many people who don’t fully understand what they are talking about. I would strongly suggest you let them and their team do the installation for you. 

Delighted with my new cooking water/heating/central heating wood burner. Thank you so much.

Baron Stael von Holstein."
