Invoice clients for lock replacements, emergency lockouts, and security installations. Professional invoices from Tidybill.
A locksmith invoice covers work installing, repairing, and replacing locks and security hardware, including emergency call-outs for lockouts, lock upgrades, high-security cylinder replacements, door handle and mechanism replacement, master key system installation, and security surveys. Emergency locksmithing is a significant part of most locksmiths' work and is charged at a premium for out-of-hours call-outs. Lock and hardware costs vary enormously depending on security grade, from basic cylinders at £20 to high-security British Standards locks at £100+. Clear invoicing is particularly important in locksmithing because the trade has historically attracted rogue operators with opaque pricing. Transparent, itemised invoices build trust and protect against payment disputes.
| Service | Typical Rate | Unit |
|---|---|---|
| Standard lock replacement (cylinder, supply and fit) | 120 | lock |
| High-security lock (British Standard, supply and fit) | 220 | lock |
| Emergency lockout (standard hours) | 80 | call-out |
| Emergency lockout (out of hours) | 140 | call-out |
| Additional keys cut | 15 | key |
| Door mechanism or handle replacement | 80 | door |
Invoice on completion of the job. For emergency call-outs, issue an invoice at the property before leaving. Clearly show the call-out fee and labour separately from parts so clients understand the full breakdown. Keep a record of the property address and work done for insurance and compliance purposes. Net immediate or net 7 for domestic clients.
