Window Cleaning Invoice Template - UK

Window cleaning services are standard-rated for VAT in the UK, meaning you must add 20% VAT to your invoice if your business is VAT registered. You're required to register for VAT once your annual turnover exceeds £85,000. If you're below this threshold, you can still voluntarily register. Always show VAT separately on your invoice as a line item, with the net amount, VAT amount, and total clearly displayed. This transparency protects you and meets HMRC requirements.

List each service separately as individual line items, specifying the type of work, quantity, and rate. For example, distinguish between exterior ground-floor windows, first-floor windows, interior cleaning, frame and sill work, and any additional services like gutter or conservatory roof cleaning. This itemization helps clients understand their charges and makes it easy to compare pricing for future quotes. It also simplifies disputes if a client questions any particular service or cost.

Net 14 or Net 30 are standard payment terms for regular window cleaning contracts, depending on your relationship and client reliability. For one-off jobs or new clients, you might request payment within 7 days or upon completion. Building long-term relationships with property managers or facilities teams often justifies more flexible terms. Consider offering a 2-3% discount for upfront payment or payment within 7 days to improve cash flow. Always state your payment terms clearly on the invoice and include your bank details.

Yes, high-access work involving ladders, scaffolding, or roof access justifies higher rates. Clearly itemize these as separate line items on your invoice—for example, "High-access window cleaning—second floor" at a premium rate compared to ground-floor work. Factor in additional safety equipment, time, and risk into your pricing. Some window cleaners also charge a callout fee for jobs requiring specialist access equipment or multiple site visits. Document these variations on your invoice so clients understand the cost difference.

Residential clients are typically invoiced after each cleaning visit, either weekly, fortnightly, or monthly depending on your arrangement. Commercial property managers or facilities teams often expect one consolidated invoice per month covering all cleaning visits and properties. Establish clear invoice schedules upfront and stick to them—regular invoicing builds trust and ensures prompt payment. For one-off or infrequent jobs, invoice immediately after completion. State your invoicing frequency on any service agreement to avoid confusion.

Yes, many window cleaners request a non-refundable deposit or holdall for high-access work, especially on period properties, listed buildings, or conservation areas where damage risk is higher. This protects your business and covers specialist equipment costs. Clearly communicate your deposit policy before work begins and detail it on your invoice or quotation. Some cleaners hold deposits as security against damage and return the full amount after a satisfactory inspection. State your deposit terms in writing to avoid disputes.

Always photograph work before and after as evidence of completion and quality. Reference these photo dates on your invoice if needed. If a client disputes the invoice, respond promptly and arrange a reinspection rather than agreeing to write-offs. For legitimate issues, offer a credit note instead of refunding cash—this maintains your records and creates a clear audit trail for your accounts. Building a professional reputation means addressing concerns fairly but protecting your business with documentation and clear payment terms.

Yes, commercial rates are typically higher than residential rates due to larger properties, more complex access requirements, and different scheduling expectations. Commercial clients like property managers expect professional invoicing, flexible scheduling, and often require written contracts or service level agreements. Your invoice should reflect these differences clearly—use separate descriptions for commercial and residential work at different rates. Building strong commercial relationships often leads to regular recurring invoices, which justifies investing in professional invoice formatting and reliable service.
