Becoming VAT-registered is a significant step for any UK business. Beyond the administrative changes, VAT registration can affect how you present your prices, how customers perceive your costs, and how you communicate with clients. Understanding these implications in advance helps you manage the transition smoothly.
This guide explains how VAT registration can change the way you price your services. It is not tax advice — always speak to a qualified accountant or tax adviser for guidance specific to your situation.
The Basics: Inclusive vs Exclusive Pricing
Before VAT registration, your prices are straightforward — the amount you charge is the amount the customer pays. After registration, you must add VAT to your prices (at the applicable rate, most commonly 20% for standard-rated services).
This creates an important decision: do you display prices inclusive or exclusive of VAT?
- Exclusive of VAT (ex-VAT): You show the base price and add VAT on top. Common in B2B markets where customers can reclaim VAT.
- Inclusive of VAT (inc-VAT): You show the total price the customer pays, with VAT included. More common in consumer-facing businesses.
The right approach depends on your customer base. If you primarily serve VAT-registered businesses, ex-VAT pricing is standard and customers will expect it. If you serve consumers or non-VAT-registered businesses, inclusive pricing is clearer and avoids surprises at checkout.
The Impact on Consumer-Facing Businesses
If your customers cannot reclaim VAT — for example, individual consumers or small businesses below the VAT threshold — adding VAT effectively increases the cost to them. A service priced at £100 becomes £120 once VAT is added at 20%.
You have a few options when this happens:
- Absorb the VAT: Keep your prices the same and accept a lower margin. This maintains competitiveness but reduces your income per sale.
- Pass VAT on to customers: Increase prices to reflect VAT. This is transparent but may affect demand if customers are price-sensitive.
- Adjust your pricing strategy: Review your overall pricing to find a balance that maintains margin without significantly impacting customer perception.
Updating Your Quotes, Invoices, and Website
Once VAT-registered, you will need to update several areas of your business:
- Invoices: VAT invoices must include your VAT registration number, the VAT rate applied, the VAT amount, and the total including VAT.
- Quotes and proposals: Make clear whether quoted prices are inclusive or exclusive of VAT to avoid confusion.
- Website pricing: Update any displayed prices to reflect VAT, and clearly state whether prices shown are inc-VAT or ex-VAT.
- Terms and conditions: Review your terms to ensure VAT is addressed correctly.
Communicating the Change to Existing Clients
If you have existing clients who are used to your pre-VAT prices, it is worth communicating the change clearly and in advance. Explain that you are now VAT-registered and that VAT will be added to future invoices. For B2B clients who can reclaim VAT, this is usually straightforward. For consumer clients, it is worth being transparent about the impact on their costs.
Keeping Your Business Address Current
HMRC will send your VAT registration number and ongoing VAT correspondence to your registered office address. You will need your VAT number before you can start issuing VAT invoices, so it is important that your address is monitored and up to date.

Summary
VAT registration changes more than just your tax obligations — it affects how you present prices, communicate with clients, and manage your invoicing. Planning ahead, updating your materials, and being transparent with customers makes the transition much smoother.
If you are approaching the VAT threshold or considering voluntary registration, speak to a qualified accountant who can help you prepare.
