About United Kingdom Consulting Invoicing
UK consultants billing over £90,000 annually must register for VAT and charge 20% on their services. Invoices must include your VAT registration number, the supply date, and a sequential invoice number. Consulting invoices reflect high-value advisory relationships and often include retainer arrangements, project-based fees, or time-and-materials billing. A professional consulting invoice conveys expertise and reinforces the value of your guidance. Clear scope descriptions, deliverable milestones, and structured payment schedules are essential for any consulting engagement.
Frequently Asked Questions
How should consulting retainers be invoiced?
Retainer fees are typically invoiced at the start of each period (monthly or quarterly). Clearly state the retainer amount, the period it covers, and what services are included. Any work beyond the retainer scope should be billed separately at your standard rate.
Can I invoice for expenses separately?
Yes. Travel, accommodation, software, and other out-of-pocket expenses should be itemized separately from your consulting fees. Attach receipts where possible and clearly label them as 'Reimbursable Expenses'. Some clients require pre-approval for expenses above a set threshold.
What is the difference between a consulting invoice and a statement of work?
A Statement of Work (SOW) is a contractual document agreed before work begins, outlining scope, deliverables, and timeline. An invoice is a payment request issued after work is completed or at agreed milestones. Both documents are important for protecting your interests.
How do I invoice international consulting clients?
For cross-border consulting, specify the invoice currency clearly, include your SWIFT/IBAN details for wire transfers, and note any applicable withholding tax obligations. Some countries require non-resident consultants to register locally for tax purposes above certain thresholds.
When do I need to include a VAT number on UK invoices?
You must display your VAT registration number on all invoices if your business is registered for VAT. VAT registration is mandatory once your taxable turnover exceeds £90,000 in a rolling 12-month period. Your VAT number follows the format GB XXX XXXX XX. Invoices without a valid VAT number cannot be used by your customers to reclaim input VAT.
What is the current UK VAT rate for invoices?
The standard UK VAT rate is 20% and applies to most goods and services. A reduced rate of 5% applies to certain items such as home energy and children's car seats. Some supplies — including most food, children's clothing, and books — are zero-rated (0%). Make sure your invoice shows the correct VAT rate for each line item.
What are the legal requirements for a valid UK invoice?
A valid UK VAT invoice must include: a unique sequential invoice number, the date of issue and the supply date, your business name, address, and VAT number, the customer's name and address, a description of the goods or services, the quantity and unit price, the VAT rate and amount for each item, and the total amount including and excluding VAT.
