This will mainly depend on the age of your domestic appliance and the manufacturer's stock of spare parts. Our engineers have a stock of the most common parts for the most common brands but we cannot guarantee that we will have the required part on board at every call. We stock parts for most common brands and normally can get them within 48 hours of his initial call-out as long as the manufacturer has them in stock. Our service engineers will order the part(s) and subject to availability we will deliver this to them within 2 working days. They will then contact you to arrange a suitable date to fit the part(s) and complete the repair. This can be considerably longer for certain brands.
