  • “We can highly recommend Duval Heating. The price was competitive and reasonable and the price quoted was what we paid. Steve was polite and worked constantly to finish the job in one day as we had no heating. He was professional and tidy in his approach to his work and on completion explained patiently how the new heating system worked. He then ran through the paperwork with us before he left. That night we sat warm and cosy thanks to his tireless efforts to complete the work in one day.”

Overall, very happy with the work that was carried out at what we feel was a very reasonable price. Would recommend and would use again.
