Setting up company phone contracts is one of the most cost-effective investments a UK business can make. A proper business contract gives you VAT recovery, tax deductions, centralised billing, and wholesale pricing that’s significantly cheaper than consumer alternatives.
This guide covers everything employers need to know: how company contracts differ from personal ones, what they cost, how to set up policies, and which networks offer the best deals in 2026.
Company Phone Contracts vs Personal Contracts
| Feature | Company Contract | Personal Contract |
|---|---|---|
| VAT | Reclaimable (20% saving) | Included, non-reclaimable |
| Corporation Tax | Deductible expense (25%) | Not deductible |
| Billing | Centralised VAT invoice | Individual statements |
| Volume discounts | 10–30% off | None |
| Support | Dedicated business line | Consumer queue |
| Management | Spend caps, usage portal | None |
What Do Company Phone Contracts Cost?
SIM Only (Employee Uses Own Phone)
| Data | Monthly | After VAT | After Corp Tax | Best Network |
|---|---|---|---|---|
| 5GB | £6 | £5.00 | £3.75 | Three |
| 10GB | £7 | £5.83 | £4.38 | Three |
| 25GB | £9 | £7.50 | £5.63 | Three |
| Unlimited | £12 | £10.00 | £7.50 | Three |
With Handset (Company Provides Phone)
| Phone + Data | Monthly | After VAT | After Corp Tax |
|---|---|---|---|
| Samsung A55 + 10GB | £18 | £15.00 | £11.25 |
| iPhone 15 + 20GB | £24 | £20.00 | £15.00 |
| iPhone 16 + Unlimited | £32 | £26.67 | £20.00 |
| Samsung S25 + Unlimited | £42 | £35.00 | £26.25 |
Setting Up Company Phone Contracts: Step by Step
- Decide SIM only vs handset: SIM only is cheapest if employees use their own phones. Handset contracts cost more but give you control over the devices and their security
- Choose a network: Compare EE, O2, Three, and Vodafone — or use a broker to compare all four
- Complete credit check: Business credit check using your company registration number. Takes 24 hours, doesn’t affect personal credit
- Order SIMs/phones: Delivered next business day. Numbers ported via PAC code within 24 hours
- Set up management: Configure spend caps, usage alerts, and policies via the network’s business portal
Company Phone Policy: What to Include
Every employer providing company phones should have a written policy covering:
- Personal use: Is personal use allowed? Most employers permit reasonable personal use — it improves employee satisfaction and avoids the hassle of employees carrying two phones
- Data usage: What constitutes acceptable use? Streaming entertainment, excessive tethering for personal devices, and premium-rate calls should be addressed
- Security: PIN/biometric lock requirements, approved apps, MDM enrollment, and what happens if the phone is lost or stolen
- Return policy: When an employee leaves, the phone and SIM must be returned. Specify the process and timeline
- Cost responsibility: Who pays for excess charges beyond the contract allowance? Clear limits prevent disputes

Company Phone Contracts for Different Business Structures
Limited Companies (Ltd)
The most straightforward setup. The company is the account holder, credit check runs against your Companies House record, and the entire cost is a corporation tax deduction. The company owns the phones and SIMs — employees use them as tools provided by the employer, just like a company laptop or vehicle.
For limited companies with 5+ employees, multi-line accounts typically qualify for volume discounts of 10–20% below published pricing. A broker can often achieve 20–30% savings at higher volumes through wholesale network tiers.
Partnerships and LLPs
Partnerships apply under the partnership name. Credit checks consider the partners’ personal credit histories. The mobile cost is a deductible partnership expense, reducing each partner’s taxable profit share. For professional partnerships (law firms, accountancies, medical practices), small company plans with professional-tier support are recommended.
Sole Traders
Sole traders apply personally. Credit check uses personal credit score. The cost is deducted from self-employment profits on your tax return. Functionally identical to a limited company contract in pricing and features — the only difference is the credit assessment method. See our dedicated sole trader business SIMs guide.
Managing Company Phone Contracts at Scale
When you have 10+ company phones, manual management becomes impractical. Network business portals provide essential tools:
Spend Management
Set per-line spending caps to prevent bill shock. When a line reaches its cap, premium-rate calls and excess data are blocked automatically. You can set different caps for different roles — directors might have a £100/month cap while standard users have £30. This prevents the single biggest source of unexpected mobile costs: accidental international calls, premium-rate numbers, and data roaming charges.
Usage Reporting
Monthly usage reports show exactly how much data, calls, and texts each line uses. This data is critical for right-sizing plans — if 40% of your team consistently uses under 3GB on a 25GB plan, moving them to 5GB plans saves significant money without affecting their experience.
Device Management
For company-owned phones, Mobile Device Management (MDM) gives IT administrators remote control: enforce password policies, push app installations, restrict certain features, and most importantly — remotely wipe company data if a phone is lost or stolen. Essential for any business handling sensitive client data.
Line Management
Adding new lines, suspending lines (for employees on long-term leave), reassigning numbers, and ordering replacement SIMs — all managed through the portal without needing to call support.
BYOD vs Company-Provided Phones
The BYOD (Bring Your Own Device) debate is one of the biggest decisions in company phone policy:
| Factor | Company Phone | BYOD + Business SIM |
|---|---|---|
| Cost | £18–42/mo per line | £6–12/mo per line |
| Security control | Full (MDM, remote wipe) | Limited (can wipe SIM, not phone) |
| Employee satisfaction | Moderate (may not like the phone choice) | High (uses own preferred phone) |
| Tax treatment | Fully deductible | Fully deductible (SIM only) |
For most SMEs under 20 employees, BYOD with business SIMs is the pragmatic choice — it’s 50–70% cheaper than providing handsets and employees prefer using their own phones.
Switching Existing Company Phones to Better Contracts
If your current company phone contracts are expensive or out of date, switching is straightforward:
- Check end dates: Review each line’s contract end date in your portal. Lines out of contract can be switched immediately
- Get comparative quotes: A broker comparison takes 60 seconds and shows what the same setup costs on today’s pricing — usually 20–40% less than contracts signed 2+ years ago
- Request PAC codes: Free to obtain, legally required to be provided within hours
- Order new SIMs: Delivered next day. Numbers port within 24 hours with minimal downtime
- Cancel old lines: Old provider handles cancellation automatically when numbers port out
The entire process — for even 50+ lines — takes under a week with proper planning.
Company Phone Insurance and Warranty
When providing company phones, consider protection options:
- Network insurance: £5–12/month per device. Covers accidental damage, theft, and loss with next-day replacement. The cost is tax-deductible and prevents the full cost of a lost phone hitting your budget
- Third-party insurance: Often cheaper at £3–8/month through specialist business mobile insurers. Compare excess amounts and claim limits before choosing
- Self-insurance: For large fleets (20+ phones), the maths may favour keeping a small reserve fund instead of paying insurance premiums. If your average annual loss rate is under 5%, self-insurance saves money in the long term
- Manufacturer warranty: All phones come with a 12-month manufacturer warranty covering defects (not accidental damage). Samsung and Apple both offer extended warranty programmes for business customers
For company-provided phones used by field workers, insurance is almost always worth it. A dropped, water-damaged, or stolen phone costs £200–1,200 to replace versus £5–12/month in premiums. One incident per year across a team of 10 justifies the insurance cost for the entire team.
Future-Proofing Your Company Phone Setup
The mobile landscape changes faster than most other business technology. Future-proof your setup by choosing 5G-capable phones and SIMs (standard on all new business contracts), selecting networks actively expanding coverage in your region, and favouring shorter contracts (12 months) that let you capitalise on annual pricing improvements. 5G business plans cost the same as 4G in 2026 — there’s no reason not to be on a 5G-ready contract.
The Bottom Line on Company Phone Contracts
A well-structured company phone contract saves money, improves productivity, and simplifies administration. Whether you’re equipping 2 employees or 200, the fundamentals are the same: choose the right mix of handset and SIM-only lines, right-size data plans to actual usage, leverage volume discounts, and actively manage the account to prevent cost creep. The tax benefits alone — VAT recovery and corporation tax deduction — make business contracts significantly cheaper than consumer alternatives for any registered UK business.
Frequently Asked Questions
Do I need a limited company for a business phone contract?
No. Sole traders, partnerships, LLPs, and limited companies all qualify. The credit check process differs slightly — sole traders are checked personally, while limited companies are checked via Companies House — but the contracts, pricing, and features are identical.
How many phones do I need for a business account?
One. There’s no minimum. A single line gets business billing, VAT invoicing, and dedicated business support. Volume discounts start at 3+ lines.
Can employees keep their personal number on a company contract?
Yes — number porting via PAC code transfers any existing personal number to the new company SIM. The employee keeps their number, and you get it on your business account.
What happens to the contract if an employee leaves?
The contract belongs to the company, not the employee. You can reassign the line to a new employee, convert it to a different number, or request early termination (paying any remaining balance).
