Sime boilers are built to last, but from time to time, even the most dependable equipment can unfortunately go wrong. Whatever the problem, we’ve got you covered. Our technical helplines are manned by highly-trained professionals who will endeavour to diagnose and resolve faults over the telephone, and where necessary, arrange for an engineer visit.
We will attend all in-warranty breakdown calls within two working days from the initial call for domestic boiler products, and three working days for commercial products.
Technical assistance is also available via our technical support team Monday to Friday between 8.30am-5.00 pm. Please call 0345 901 1114 and select option 3 on the automated menu. Outside of these hours you can email us on email@example.com and we’ll always endeavour to respond within 24-hours. Our product managers are also active members of the Gas Chat Facebook group and are happy to answer your questions within this forum.
