“Castle Heating had been recommended by a neighbour and I'm so glad that they had been! Twice Karl has come to my rescue - following a water leak problem - first time in my kitchen - the second time from my hot water cylinder upstairs - when he had to drain my old tank and then replace this with a new one. Both times he has come to sort this out as soon as he possibly could. I cannot recommend him enough. He is always so reassuring, professional, tidy with his work and a really nice all round person and another added plus - is that he is local too! I recommend him to all my friends now.”

Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 8 years on the register also points to an established business rather than a brand-new one.
