Lawyer Invoice Template - UK

VAT treatment for legal services depends on your registration status and service type. If you're VAT-registered, most legal services are standard-rated at 20%. However, some specific services may have different treatments—always check HMRC guidance. Include a clear VAT breakdown on your invoice showing the rate and amount. If you're not VAT-registered, state "No VAT charged" to avoid client confusion. Make sure your invoice displays your VAT registration number if registered. Update clients if your registration status changes mid-engagement.

The Solicitors Regulation Authority (SRA) requires invoices to clearly identify services provided and be accurate and transparent. Your invoice must show your firm's name, SRA number, and invoice date. All charges must be justified and easily understood by clients. Keep detailed time records to support hourly billing claims. You must comply with SRA requirements around costs information and client communication. Include your firm's complaints procedure and contact details on invoices. Failure to meet these standards could result in professional disciplinary action.

Legal service descriptions should be specific enough for clients to understand what they're paying for, but concise enough to remain clear. Instead of vague entries, use descriptions like "Contract review for commercial lease" or "Client consultation regarding employment dispute." Break down different service types separately with their respective rates. Include the date(s) the work was performed and time spent for hourly billing. Avoid combining multiple unrelated services into one line item. Clear descriptions reduce disputes and demonstrate professional competence.

Both approaches are legitimate depending on your practice type and client relationship. Hourly billing suits one-off matters where scope is uncertain and you want to charge for actual time invested. Retainers work better for ongoing relationships where you provide continuous advice or representation over extended periods. Many practices use hybrid models: a retainer for general advisory work plus hourly charges for additional services. Your invoice template should accommodate your chosen structure. Always communicate your billing method clearly to clients before engagement begins.

Specify your payment deadline clearly—typically 14 to 30 days from the invoice date. Under the Late Payment of Commercial Debts (Interest) Act 1998, you have the statutory right to charge interest on overdue invoices at 8% plus the Bank of England base rate. State your interest rate on the invoice. Include your payment methods (bank transfer, cheque, card) and banking details. Mention any early payment discounts if offered. Reference your dispute resolution process and your right to suspend services if payment isn't received within your timeframe.

Time records must be contemporaneous (recorded when the work occurs) and sufficiently detailed to support invoice charges. Most firms use six-minute or 15-minute billing units; consistency matters. Record the date, duration, and specific activity for each entry. The SRA expects records to accurately reflect work performed. Backdating or rounding time incorrectly constitutes overcharging and may trigger professional complaints. Your time records form the foundation of your invoice—inaccuracy damages client trust and exposes you to disputes. Retain all records for at least six years.

Respond promptly and professionally to any dispute. Review your time records and verify the work actually performed supports the charge. If accurate, explain your rationale and reference the services provided in detail. Cite any prior agreement about fees or billing approach. If you identify a legitimate concern, consider whether a modest credit preserves the relationship while protecting your practice standards. Document all communications and resolutions. If the dispute escalates unresolved, refer to your terms and conditions regarding dispute procedures. Billing disputes can trigger professional conduct complaints.

Keep detailed time records showing the date, duration, and description of work for every billable activity. Retain copies of all invoices and payment documentation. Maintain evidence of client instructions and fee agreements (engagement letters, quotes, cost estimates). Keep file notes and work product related to each invoice item. The SRA requires records to be kept for at least six years. These documents protect you if disputes arise or complaints are raised. Organized records also support VAT returns and tax accounting. Practice management software can automate record-keeping and reduce errors.
