Ancillary Costs Following Appliance Failure

[Soffit]

I purchased an extractor fan from a supplier, which developed a fault. The company have agreed to a replacement. Removing the faulty appliance and fitting the new one involves electrical work. To get certification of the work I need to use a qualified electrician. The supplier of the fan say that they will not pay for the costs of the electrician.

I feel that through no fault of my own, I am being required to incur costs relating to a faulty item supplied to me. Is there any way that I can get the supplier to cover the fitting costs?

I've done a bit of further research and I think that the Consumer Rights Act 2015 provides for being able to make a claim for reimbursement for "consequential losses". If there is anyone with some legal knowledge on this who can confirm it, I would be grateful?
