What if I Don’t Have a Bacs Service User Number (SUN)?


In the world of financial transactions, efficiency, reliability, and security are paramount. Whether you’re a business owner, a finance professional, or simply someone looking to make regular payments, having the right tools and processes in place is essential. One such tool in the UK’s financial landscape is the Bacs Service User Number (SUN). But what happens if you don’t have one? In this article, we’ll explore what a Bacs SUN is, why it’s important, and what you can do if you find yourself without one.


Understanding the Bacs Service User Number (SUN)


Before we delve into the scenario of not having a Bacs SUN, let’s first clarify what it is. The Bacs Service User Number, often abbreviated as SUN, is a unique identifier issued by Bacs Payment Schemes Limited, the organisation responsible for the clearing and settlement of automated payment methods in the UK. This number is assigned to organisations that wish to make electronic payments, including Direct Debits and Bacs Direct Credits, through the Bacs system.


Why Having a Bacs SUN is Crucial


Regulatory Compliance: First and foremost, having a Bacs SUN is a legal requirement for businesses that wish to make electronic payments using the Bacs system. Failure to obtain and use a valid SUN can result in regulatory penalties and fines.


Efficient Payment Processing: Bacs is a trusted and widely used payment method in the UK. It allows for the seamless processing of payments, making it an efficient choice for businesses and organisations that need to collect or disburse funds on a regular basis.


Cost Savings: Using Bacs for payments can be cost-effective, especially for businesses that handle a high volume of transactions. It eliminates the need for costly paper-based processes and reduces administrative overhead.


Customer Convenience: For consumers, Bacs payments, such as Direct Debits, offer convenience and reliability. Many individuals and households use Direct Debits to pay bills, subscriptions, and other regular expenses.


What to Do If You Don’t Have a Bacs SUN


If you find yourself without a Bacs SUN but need to make electronic payments, here are the steps you can take to rectify the situation:


Apply for a Bacs SUN: The first and most straightforward option is to apply for a Bacs SUN. You can do this by contacting Bacs Payment Schemes Limited directly or working through a Bacs-approved bureau service. The application process involves providing information about your organisation, its financial standing, and its intended use of the Bacs system.


Consider Bacs Bureau Services: If you don’t want to go through the process of obtaining your own Bacs SUN, you can consider using a Bacs bureau service. These services act as intermediaries between your organisation and Bacs, handling the technical aspects of payment processing on your behalf.


Explore Alternative Payment Methods: While Bacs is a popular payment method, it’s not the only one available. Depending on your needs, you may explore other electronic payment options, such as Faster Payments or CHAPS (Clearing House Automated Payment System). Each of these methods has its own advantages and considerations.


Consult with Financial Experts: If you’re uncertain about the best course of action, then consult with one of FastPay’s highly skilled experts. They will be able to provide you with guidance tailored to your specific situation and help you make an informed decision.




In the world of electronic payments in the UK, having a Bacs Service User Number (SUN) is crucial for regulatory compliance, efficient payment processing, and cost savings. However, if you find yourself without a Bacs SUN, it’s not the end of the road. There are options available to help you navigate this situation, including applying for a SUN, using bureau services, exploring alternative payment methods, or seeking expert advice. The key is to assess your organisation’s needs and choose the path that best aligns with your objectives and circumstances. Ultimately, having a Bacs SUN can open doors to smoother, more cost-effective financial operations in the UK.
