Published: 17 March 2026 • Compare The Networks
Cancelling a business mobile contract in the UK is not as straightforward as cancelling a personal one. You may be locked into multi-year agreements, face substantial early termination fees, or have dozens of lines that all need porting at the same time. This guide explains your rights, the costs involved, how to cancel with each major network, and how the Compare The Networks switching promise can help you exit your current contract and move to a better deal.
Understanding Business Mobile Contract Terms
Business mobile contracts in the UK typically run for 24 or 36 months. Unlike consumer contracts (which are covered by Ofcom’s auto-switch rules and the one-month notice period after the minimum term), business-to-business (B2B) contracts are governed primarily by the terms and conditions you signed when you took out the contract. This means:
- You may be tied in for the full contract term with no right to cancel early without paying a fee
- The cancellation process and notice period are defined in your contract, not by Ofcom consumer rules
- Auto-renewal clauses may lock you into a new minimum term if you do not give notice before the contract expires
- Multi-line contracts may require all lines to be cancelled together, or may allow partial cancellation
Important: Always check your specific contract terms before assuming any of the general rules below apply. Business contracts vary significantly between networks and between different account types.
Check Your Contract Status: Text INFO to 85075
The quickest way to find out where you stand is to text INFO to 85075 from any mobile on your account. This is an OFCOM-mandated service available on all UK networks. Your provider must respond within one working day with:
- Your contract end date
- Any early termination charges you would face if you left now
- Instructions for requesting your PAC or STAC code
For business accounts with multiple lines, you may need to text from each line individually or contact your account manager for a full account overview.
Early Termination Fees: What Will It Cost?
If you cancel a business mobile contract before the minimum term ends, you will usually have to pay an early termination fee (ETF). For business contracts, this is typically calculated as:
| Component | How It’s Calculated |
|---|---|
| Remaining monthly charges | Your monthly line rental × number of months left on the contract |
| Handset subsidy | If a phone was included, the remaining balance of the handset cost |
| Discount clawback | Some networks reclaim multi-line or loyalty discounts if you leave early |
| Admin / processing fee | Some networks charge a flat admin fee (typically competitive rates–competitive rates) |
Example: Early Termination Cost
A business with 10 lines on a 36-month contract at competitive rates, cancelling with 18 months remaining:
- Remaining monthly charges: 10 lines × competitive rates × 18 months = competitive rates
- Handset subsidy balance: 10 lines × competitive rates remaining = competitive rates
- Admin fees: 10 lines × competitive rates = competitive rates
- Total ETF: competitive rates
This is why many businesses feel trapped in contracts that no longer meet their needs. However, there are ways to reduce or eliminate these costs, which we cover below.

The cancellation process varies between networks. Here is how to cancel or request a PAC code from each major UK business mobile provider:
EE Business
- Phone: Call 158 from your EE phone or 0800 956 6000 from any phone
- Online: Log in to your EE Business account and request cancellation or a PAC code
- Notice period: Typically 30 days after the minimum term ends
- PAC code: Request via text (send “PAC” to 65075) for consumer, but business accounts usually need to call the business team
- Key note: EE business contracts often have auto-renewal clauses. Check your renewal date and give notice at least 30 days before
Vodafone Business
- Phone: Call 191 from your Vodafone phone or 03333 040 191 from any phone
- Online: Log in to Vodafone Business Online and submit a cancellation request
- Notice period: Usually 30 days after minimum term
- PAC code: Business accounts must request PAC codes through the business team, not via the consumer text service
- Key note: Vodafone may offer retention deals — always ask, but compare them against quotes from other providers before accepting
O2 Business
- Phone: Call 8002 from your O2 phone or 0344 809 0202 from any phone
- Online: Contact O2 Business through My O2 Business portal
- Notice period: 30 days after minimum term
- PAC code: Request through your O2 Business account manager or the business team
- Key note: O2 business contracts include Roam at Home — 25GB EU data plus inclusive minutes and texts at no extra cost. Factor this into your comparison when considering a switch
Three Business
- Phone: Call 333 from your Three phone or 0333 338 1001 from any phone
- Online: Contact Three Business Support
- Notice period: 30 days after minimum term
- PAC code: Request via the business support team
- Key note: Three often has the most competitive retention offers. Always get a written quote before accepting a verbal offer over the phone
PAC Codes and STAC Codes: What’s the Difference?
When leaving a business mobile contract, you will need either a PAC code or a STAC code:
| Code | What It Does | When to Use It |
|---|---|---|
| PAC (Porting Authorisation Code) | Transfers your existing phone number to a new provider | When you want to keep your current business number |
| STAC (Service Termination Authorisation Code) | Cancels your line without transferring the number | When you do not need to keep the number (e.g., replacing with a new number) |
For business accounts: PAC and STAC codes are valid for 30 days. Once you give the code to your new provider, the switch typically happens within one working day. Your old contract is automatically cancelled when the port completes — you do not need to separately cancel with your old provider.
Bulk PAC codes: If you are porting multiple business lines, you can request bulk PAC codes from your current provider. This is essential for businesses switching 5, 10, 50, or more lines at once. Your new provider (or a broker like Compare The Networks) can manage the bulk porting process for you.
The CTN Switching Promise: How It Works
At Compare The Networks, we understand that early termination fees are often the biggest barrier to switching. That is why we offer our switching promise:
- We will pay agreed early termination fees when you switch your business mobiles to us
- We negotiate with the new network to cover or offset your exit costs
- We handle the entire switching process — PAC codes, number porting, device setup
- There is no cost to you for our comparison and switching service
How it works in practice: We review your current contract, calculate your early exit fees, and then find a new deal where the savings over the new contract term exceed the exit costs. In many cases, the new network will contribute towards your exit fees as part of their acquisition offer. Terms apply — the fees covered are the agreed amount, not necessarily all remaining fees.
When Can You Cancel Without Paying Fees?
There are specific circumstances where you may be able to exit a business mobile contract without paying early termination fees:
1. After the Minimum Term Expires
Once your minimum contract period (24 or 36 months) has ended, you can cancel with the standard notice period (usually 30 days) without any ETF. Be aware of auto-renewal clauses that may commit you to a new minimum term if you do not give timely notice.
2. Price Increase Beyond the Contractual Amount
All major UK networks apply an annual price increase each April. Since January 2025, Ofcom has banned CPI/RPI-linked price increases, requiring networks to state the increase in pounds and pence. The current standard is a fixed competitive rates per month increase each April for O2, Vodafone, EE, and most VoIP providers (Sky Broadband is competitive rates fixed).
This increase is written into your contract from the start, so it is not grounds for penalty-free cancellation. However, if a network were to impose an increase beyond the contractually agreed amount, this would be a material change to your contract terms, and you would have the right to exit without penalty within a reasonable timeframe (usually 30 days from notification).
3. Network Breach of Contract
If your provider materially breaches the contract — for example, consistently failing to provide the service level agreed, changing key terms without proper notice, or experiencing prolonged network outages — you may have grounds to terminate without penalty. Document any issues carefully and seek legal advice before relying on this route, as B2B contracts often have specific dispute resolution procedures.
4. Cooling-Off Period
Consumer contracts have a 14-day cooling-off period. Business contracts may not have this right, depending on the terms. Some networks do offer a business cooling-off period as a goodwill gesture, but it is not a legal requirement for B2B contracts. Check your specific terms.
5. Network Closure or Merger
If your network ceases to operate or merges with another provider, the terms of the transition will determine your rights. You may be offered equivalent terms on the acquiring network or given the option to exit.
Ofcom Rules for Business Mobile Contracts
Ofcom’s regulatory framework treats business and consumer mobile contracts differently:
| Rule | Consumer Contracts | Business Contracts (B2B) |
|---|---|---|
| Auto-switch (PAC by text) | Yes — request PAC by texting 65075 | Not always available — may need to call business team |
| 14-day cooling-off period | Yes (Distance Selling Regulations) | Not guaranteed — depends on contract terms |
| Maximum contract length | 24 months (36 months for handset finance) | No maximum — 36-month terms are common |
| End-of-contract notification | Required — network must notify you before contract ends | May not be required for B2B contracts |
| Mid-contract price increase exit right | Can exit if increase exceeds contractual terms | Same principle applies, but B2B contracts are more flexible for providers |
| Annual price increase format | Must be in £ and pence (not CPI/RPI linked) | B2B contracts technically exempt from Ofcom ban on CPI/RPI increases, but most networks have adopted £ and pence format anyway |
Key takeaway: Business mobile customers have fewer automatic protections than consumers. Your rights are primarily defined by your contract, not by Ofcom’s consumer rules. This makes it even more important to review your contract terms carefully and seek expert advice before switching.
Step-by-Step: How to Switch Your Business Mobiles
Here is the recommended process for switching your business mobile provider:
Step 1: Review Your Current Contract
Check your contract end date, notice period, early termination charges, and any auto-renewal clauses. If you cannot find the original contract, call your provider and ask for a summary of your current terms.
Step 2: Get a Comparison Quote
Use our free quote service to compare deals across EE, Vodafone, O2, and Three. We will show you the total cost of switching including any early exit fees, so you can make a fully informed decision.
Step 3: Request PAC Codes
Once you have decided to switch, request PAC codes for all the numbers you want to keep. For business accounts with multiple lines, request bulk PAC codes through your current provider’s business team. PAC codes are valid for 30 days.
Step 4: Set Up Your New Contract
Your new provider will set up your new lines and schedule the number ports. The port typically completes within one working day. During the port, there may be a brief interruption of service (usually a few hours).
Step 5: Confirm Cancellation of Old Contract
Once the port is complete, your old contract is automatically cancelled for the ported lines. Verify that the old provider has stopped billing you and check your final bill for any unexpected charges.
Common Mistakes to Avoid
- Not checking auto-renewal dates — many businesses miss the window and get locked in for another 12–24 months
- Cancelling before getting PAC codes — if you cancel your lines without requesting PAC codes first, you will lose your business numbers permanently
- Assuming consumer rules apply — the 14-day cooling-off period and auto-switch by text may not apply to your business contract
- Not negotiating — your current provider will almost always offer a retention deal. Get it in writing and compare it against external quotes
- Forgetting about data — back up any important data on company phones before switching, especially if MDM will wipe devices during the transition

Get a Free QuoteQ: Can I cancel my business mobile contract early?
Yes, but you will usually have to pay an early termination fee. This is typically the remaining monthly charges for the rest of your contract term, plus any outstanding handset balance. The exact amount depends on your contract terms. Compare The Networks can help you offset these costs through our switching promise.
Q: How much does it cost to cancel a business mobile contract early?
The cost varies depending on how many months are left on your contract, your monthly line rental, and whether handsets are included. As a rough guide, expect to pay the remaining monthly charges for all lines plus any handset subsidy balance. For a 10-line contract with 12 months remaining competitive rates/line/month, that could be competitive rates or more plus VAT.
Q: What is a PAC code and how do I get one for a business account?
A PAC (Porting Authorisation Code) allows you to transfer your existing phone number to a new provider. For business accounts, you usually need to contact your provider’s business team by phone to request PAC codes. The consumer text-to-switch service (texting PAC to 65075) may not work for business accounts. PAC codes are valid for 30 days.
Q: Can I cancel some lines but keep others on the same business account?
This depends on your contract. Some business contracts allow partial cancellation (individual lines), while others require all lines to be cancelled together. Check your contract terms or ask your provider. Partial cancellation may affect any multi-line discount you are receiving.
Q: What is the CTN switching promise?
Compare The Networks will pay agreed early termination fees when you switch your business mobiles through us. We negotiate with the new network to cover or offset your exit costs, making it possible to switch even if you are mid-contract. Terms apply — the fees covered are the agreed amount, not necessarily all remaining fees. Learn more about our switching promise.
Q: Do I need to give notice before cancelling a business mobile contract?
Yes. Most business contracts require 30 days’ written notice after the minimum term expires. If you are cancelling mid-contract (paying an ETF), the notice period still applies. If you are porting your number using a PAC code, the cancellation happens automatically when the port completes, but you should still formally notify your provider.
Q: Can I cancel without fees if my network raises prices?
It depends on the price increase. The standard annual increase is a fixed competitive rates per month each April, which is written into your contract from the start — this is not grounds for penalty-free cancellation. However, if a network imposes an increase beyond the contractually agreed amount, this would be a material change to your contract, and you would have the right to exit without penalty within the notification period.
Q: How long does it take to switch business mobile provider?
Once you provide your PAC codes to the new provider, the number port typically completes within one working day. However, the overall process — including getting quotes, negotiating deals, requesting PAC codes, and setting up new contracts — usually takes one to two weeks. For large fleets (50+ lines), allow three to four weeks for a managed transition.
