Taking out mobile phone contracts in your limited company’s name is a different process from a personal contract or even a sole-trader plan. The credit checks are run against Companies House records, the VAT treatment is more generous, and the contracts themselves are governed by business law rather than consumer rights. This guide explains exactly how Ltd-company mobile contracts work in 2026 — from the credit-check process to the tax efficiencies most accountants forget to mention.
If you trade as a sole trader instead, our Sole Trader Business SIMs guide covers your route. For wider context, see our shortlist of the best UK business mobile plans for 2026.
What Counts as a Limited Company Mobile Contract?
A limited company mobile contract is taken out in the name of a UK Ltd entity registered at Companies House. The company is the legal customer. The director (or another authorised signatory) signs on the company’s behalf, and invoices are addressed to the registered office.
That sounds bureaucratic, but it changes three practical things:
- The credit check is on the company, using filed accounts, payment history with suppliers and any County Court Judgments. New Ltd companies (under 2 years of accounts) usually need a director’s personal guarantee to pass.
- VAT is reclaimed at 20% on the business-use portion of the bill — including the device, the airtime, roaming and add-ons. Personal contracts can’t reclaim VAT at all.
- The handset is a company asset. It sits on your balance sheet, depreciates over the contract term, and reduces Corporation Tax through capital allowances or P&L expensing.
For most directors, that combination is worth £150–£400 per line per year compared to running the same phone personally.
Who Can Take Out a Ltd-Company Mobile Contract?
Any UK limited company that can pass the network’s credit check. In practice, that means three groups:
1. Established Limited Companies (2+ Years Trading)
If you have two sets of filed accounts and a clean payment record, networks treat you as low-risk. You’ll get the standard published business tariffs, no upfront security deposit, and contracts in the company name without a personal guarantee. EE, Vodafone and O2 all have dedicated SME teams for this segment.
2. New Limited Companies (Under 2 Years)
Newer Ltd companies are flagged as “thin file” and almost always need a director’s personal guarantee. That doesn’t mean rejection — it means the contract is in the company name, but the director is liable personally if the company defaults. Most networks accept this if the director’s personal credit is good.
Some specialist business resellers (including Connection Technologies) work with networks who waive the guarantee on smaller orders for newly-formed Ltd companies, particularly when there’s evidence of trading (live invoices, business bank account in credit, VAT registration).
3. Single-Director Personal Service Companies (PSCs)
Contractors operating through a Ltd company — IT consultants, locum doctors, freelance designers — qualify as Ltd-company customers. The credit check is the same. The tax position is sometimes more complex if you’re inside IR35, so check with your accountant before assigning a phone for personal use.
How the Credit Check Works
Network credit teams pull data from Experian Business, Equifax Business and Companies House. They look at:
- Filed accounts — net assets, turnover, liquidity ratio. Companies showing negative net assets struggle to pass without a guarantee.
- Payment performance — how promptly you pay other suppliers (this is reported to credit bureaus by HMRC, utilities and B2B vendors).
- CCJs and insolvency events — any active County Court Judgment is a near-automatic decline.
- Director profile — for newer companies, the director’s personal credit file is also checked.
- Industry sector — some networks have appetite limits for high-risk sectors (construction subcontracting, hospitality, taxi/PHV).
If your check fails, you have three options: provide a director’s personal guarantee, pay a refundable security deposit (usually £50–£250 per line), or use a specialist business reseller with broader credit appetite.
Limited Company Mobile Contract Pricing in 2026
Pricing for Ltd-company contracts in May 2026 sits roughly in these brackets, ex-VAT, on 24-month terms with a basic smartphone:
| Plan type | Data | Typical monthly cost (ex-VAT) |
|---|---|---|
| SIM-only (no handset) | 5 GB | from £8 |
| SIM-only | 50 GB | from £12 |
| SIM-only | Unlimited | from £18 |
| SIM + mid-range handset (e.g. Galaxy A56, Pixel 9a) | 50 GB | from £25 |
| SIM + flagship (iPhone 17, Galaxy S25) | 100 GB | from £45 |
| SIM + flagship Pro / Ultra | Unlimited | from £55 |
All figures are ex-VAT, indicative for May 2026, and assume no upfront device payment. Request a tailored quote for exact pricing on your line count and handset choice.
Why Ltd Pricing Is Lower Than Consumer Pricing
A like-for-like SIM-only plan can be 20–40% cheaper on a business tariff than the consumer one. Three reasons:
- Networks treat business customers as lower churn — Ltd companies don’t switch on a whim, so the cost of acquisition is amortised over a longer relationship.
- Business contracts bundle multiple lines, so the discount per line scales with fleet size.
- Business plans don’t carry the marketing overhead of consumer plans (no “free Disney+” subsidies).

VAT and Tax Treatment for Ltd-Company Phones
This is where Ltd-company contracts genuinely save money compared to personal ones. There are four tax mechanics worth understanding.
1. VAT Reclaim on Airtime and Device
If the contract is in the company name and the line is used for business, you can reclaim 100% of the VAT — on the monthly bill, the upfront device cost (if any) and any add-ons. For a £45/month flagship contract, that’s £108/year of VAT recovered per line.
HMRC accepts that incidental personal use of a business mobile is fine and doesn’t require apportionment, provided the contract is in the company name and the phone is “made available” to the employee for business use. The same is not true for sole traders, who must apportion VAT by use percentage.
2. Corporation Tax Deduction on Monthly Costs
The full ex-VAT monthly cost is deductible against Corporation Tax. At the 25% main rate, that’s a 25% saving on top of the VAT reclaim. A £45/month line therefore costs the Ltd company about £27 net after both taxes — versus the £54 a consumer would pay all-in.
3. Device as a Capital Asset
If the handset cost is itemised separately (rather than amortised into the airtime), it can be treated as a capital purchase and qualify for the Annual Investment Allowance — 100% deduction in year one, up to the AIA limit. Most companies don’t bother, but for fleet purchases this can make a meaningful difference.
4. P11D Treatment for Personal Use
HMRC’s “one mobile phone per employee” rule is generous: a company can provide one mobile phone per employee for both business and private use, with no Benefit-in-Kind charge, provided the contract is in the company name. The director counts as an employee for this purpose.
The exemption only covers one phone per person, and it must be a mobile (not a tablet or smartwatch on a separate line). A second handset on the same line would trigger a P11D entry.
Best Networks for Limited Companies in 2026
All four UK MNOs and several specialist resellers serve the Ltd-company market. Here’s a practical breakdown of where each fits.
EE Business — Best for Mixed Fleets
EE has the strongest UK 5G coverage (per Ofcom’s 2025 Connected Nations report, EE leads in geographic 5G availability) and the broadest business plan catalogue. Its “Smart Business” tariffs let you mix and match data allowances across lines on a single bill. Strong choice for SMEs with a mix of office-based and field staff.
Vodafone Business — Best for International Roaming
Vodafone’s “Global Roaming Plus” includes 100+ countries on most business plans, which matters if you have any overseas trade. Its 5G SA (standalone) network coverage is improving. See our Vodafone business deals roundup for current promotions.
O2 Business — Best for Plan Flexibility
O2 (now part of VMO2) is strong on flexible terms — 12-month and even 1-month rolling business contracts are available, which is unusual. Useful for project-based hires or contractors on short engagements.
Three Business — Best Value on Unlimited Data
Three Business consistently leads on unlimited-data pricing for SMEs, often £4–£8/month cheaper than EE/Vodafone like-for-like. Coverage is the trade-off — Three’s 5G footprint is the smallest of the four, so check coverage at your key business locations first using our UK business mobile coverage checker.
Connection Technologies (Specialist Reseller)
As a specialist B2B reseller, we work across all four networks plus Lebara Business and Mobile by Sainsbury’s Business. The advantage is consolidated billing, broader credit appetite for newer Ltd companies, and the ability to mix networks within a single fleet (e.g. EE for field staff in rural areas, Three for office-based unlimited-data users).
Contract Lengths: 12, 24 or 36 Months?
For Ltd companies, the right contract length depends on cash flow priorities and headcount stability.
- 12-month contracts — best for high-growth Ltd companies whose headcount may double or halve within the year. Higher monthly cost (typically +15–20%), but no early-termination penalty after month 12.
- 24-month contracts — the default for most established Ltd companies. Best blend of monthly cost and flexibility.
- 36-month contracts — best when you want the lowest possible monthly cost on a flagship handset. Effectively spreads the device cost over 3 years.
If you’re considering a long contract, factor in the early-termination charge (ETF) liability if you need to exit. Our guide to cancelling a business mobile contract early walks through the calculation.
Common Mistakes Limited Companies Make
1. Buying Personal Plans for Director Use
Directors often default to taking a personal contract and putting it through expenses. This loses the VAT reclaim, the BiK exemption and the Corporation Tax efficiency. Always take the contract in the Ltd name from day one.
2. Letting Each Employee Pick Their Own Network
Multi-network fleets work, but they create billing complexity and dilute the volume discount. For most Ltd companies under 25 lines, sticking to a single network or a single specialist reseller is more efficient.
3. Ignoring the Mid-Contract Price Rise (MCPR) Clause
Since Ofcom’s January 2025 ban on inflation-linked rises, networks have moved to fixed-£ annual increases (typically £1.50–£2.00/month per line) baked into the contract from year two onwards. Read the small print before signing — these add up across a fleet.
4. Forgetting About the In-Life Cost
The headline monthly cost is only part of the picture. Excess data, international roaming, premium-rate calls and insurance add-ons can quietly inflate a £30 plan to £45. Set a spend cap or alert at the contract start. Our UK business mobile spend cap guide explains how.
How to Switch a Personal Contract to a Limited Company
If you’re already running a personal mobile contract and want to migrate it into the Ltd company, the process is:
- Take out a new business contract in the company name (the credit check happens here).
- Request a PAC code from your existing personal provider.
- Port the number to the new business SIM during the cooling-off period.
- Cancel the personal contract within its notice period to avoid ETF charges.
For most personal contracts, you’ll have to serve out the remainder of the minimum term unless you can demonstrate a hardship case. The number portability itself is free and Ofcom-mandated. Our PAC code switching guide covers the mechanics.
Should a Sole Trader Become a Ltd Company Just for the Mobile Tax Relief?
No. The tax saving on a single mobile line is around £150–£300 per year — not enough to justify the £200–£800 annual cost of running a Ltd company (accounting fees, Confirmation Statement, Corporation Tax filing). The Ltd-vs-sole-trader decision should be made on overall trading profit, IR35 exposure and personal liability — not on phone contracts.
If you’re already a Ltd company, take the contract in the company name. If you’re a sole trader, our sole trader business mobile guide walks through the alternatives.
Quick Decision Framework
For a UK limited company shopping for a business mobile contract in 2026:
- 1–4 lines, established Ltd: SIM-only with a separately purchased handset usually beats a bundled deal on Total Cost of Ownership.
- 5–20 lines: A specialist business reseller (Connection Technologies, Vorboss, Onecom) typically beats direct network pricing thanks to volume discounts and fewer dead-line costs.
- 20+ lines: You’re in fleet territory — see our enterprise fleet management guide and ask for a tailored RFP.
- Mixed roles (office + field): Mix-and-match plans across one bill (EE Smart Business or Onecom Aggregate) save more than picking the cheapest single tariff.
- Newer Ltd, thin credit file: Specialist business resellers are usually more flexible than going direct. Be prepared to provide a director’s guarantee on the first 1–2 lines.

Frequently Asked Questions
Yes, but typically only if the Ltd company has at least two years of filed accounts showing healthy trading and a clean credit profile. Newer Ltd companies (under 2 years) almost always need a director’s personal guarantee on the first business mobile contract. Specialist business resellers can sometimes waive the guarantee for small initial orders where there’s evidence of active trading.
A UK Ltd company can reclaim 100% of the VAT (currently 20%) on business mobile contracts in the company name, including the airtime, the device, roaming and add-ons. HMRC accepts incidental personal use without requiring an apportionment, provided the contract is in the company’s name and the phone is provided to an employee or director for business use.
No, provided the contract is in the company’s name and only one mobile phone is provided per employee (the director counts as an employee). HMRC’s “one mobile phone per employee” rule means there’s no P11D entry and no Benefit-in-Kind tax charge, even if the phone is used for personal calls. A second handset on a separate line would trigger a BiK charge.
You can claim the business-use portion of a personal contract as a Corporation Tax expense, but you cannot reclaim the VAT and you cannot use the Benefit-in-Kind exemption. Both the VAT reclaim and the BiK exemption only apply when the contract itself is in the Ltd company’s name. For most directors it’s worth switching the contract to the company.
For an established Ltd company with two years of filed accounts, most networks return a credit decision in under an hour during business hours. For newer companies or those needing a director’s guarantee, allow 24–48 hours for the additional checks. Specialist business resellers like Connection Technologies can usually pre-check credit before formal submission to avoid wasted applications.
SIM-only Ltd-company plans start from around £8/month ex-VAT for 5 GB of data on a 24-month term. With a flagship handset (iPhone 17, Galaxy S25) included, prices start from around £45/month ex-VAT for 100 GB. Multi-line discounts and specialist reseller pricing can take these figures lower for fleets of 5+ lines.
