Dear Customer name,

Re: Overdue invoice INV-001 — £3,500.00

Our records show that invoice INV-001, dated 20 April 2026, in the sum of £3,500.00, remains unpaid. As of today it is 35 days overdue.

Under the Late Payment of Commercial Debts (Interest) Act 1998, we are entitled to claim £41.95 in statutory interest (calculated at 12.5% per annum — Bank of England base rate plus 8%) together with £70.00 in fixed compensation. The total now payable is £3,611.95.

Please arrange settlement of the full sum within 7 days of the date of this letter. If we do not receive payment by then we reserve the right to take further action to recover the debt, including formal proceedings, without further notice.

If you believe payment has already been made, or if you wish to discuss this matter, please contact us at the earliest opportunity.

Yours faithfully,

Your name
