If you phone an 0800 or 0845 number this is usually a call centre, call centres normally mean higher costs, due to the locksmith being part of a franchise, the normal cost difference is anything from 15% to 60% due to paying a royalty fee.
Always look for a CRB Checked locksmith then you know you can trust the locksmith in your home. Look for the logo below
Always check the locksmith has Public Liability cover for any little miss haps that may occur.
Look for customer testimonials on website, video ones are normally more authentic.
Dont ask for a price over the phone, a good locksmith would rather come and see your requirements and give you an accruate no obligation quotation.
Always only pay the price you were quoted. Many locksmiths quote cheap on the phone only to hike up the price when job has been completed.
Always agree the price prior to the start of any work including VAT
