Initially called iGas Heating early one freezing cold morning, they came over almost immediately and managed to very quickly put in a good temporary measure to get us up and working again while a part was ordered. The actual work to fix the issue was carried out by two people, both of whom I'd be very happy to call back if there was any other problems. Polite and professional, work was carried out for the agreed costs, no surprises. The central heating issue was in fact several issues together but all were resolved in the end. Great service, would call them in again.
