The 3 people I deal with most at Delta are Richard, Lisa and Ashley. They never let me down and are always ready to help and assist with any enquiries I have. Most importantly they understand that my business often has urgent inquiries that others dont and have always been very capable of competitive pricing and getting equipment to me in good time enabling me to meet very strict customer deadlines. Delta fire is highly recommended my me.

Fantastic equipment and customer service. Would high recommend Delta Fire to any company looking for fire service equipment. After doing a lot of market research, I found and contacted Delta Fire to get more information about their equipment. Any questions I had where answered, they helped me look at my company's needs and pick which products where best suited. Extremely helpful. To add the very long warranty and that they are UK made is what separates the from the rest. Thank you guys for all your help. 10/10
