We keep paying simple. Order online and pay by card, wallet or Klarna — or, for repair services, book the job now and pay only once the repair is done. All online payments are handled by Stripe, so your card details never touch our servers.

Ways to pay online




Credit & debit cards

Visa · Mastercard · American Express · Maestro

Pay securely at checkout. Payments are processed by Stripe with 3-D Secure (Verified by Visa, Mastercard Identity Check), and we never see or store your full card number.


Apple Pay & Google Pay

One-tap checkout on supported devices

If your device supports it, the wallet button appears automatically at checkout — no card typing, no account needed.

Klarna — buy now, pay later

Pay later or split into instalments

Spread the cost of a repair or replacement unit. Klarna runs its own eligibility check at checkout, and the terms shown there apply.

Payment After Repair

Nothing to pay today · repair services only

Confirm your order with no upfront payment, send us your unit, and we contact you for payment once the repair is complete — by secure link, card over the phone or bank transfer. Your unit ships back as soon as payment clears.

Other ways to pay

  • Over the phone — call 01884 798090 and pay by card with our team.
  • Secure payment link — we can email you a Stripe link to pay in your own time.
  • In person — card or cash at our workshop in Uffculme, Devon, for on-site fitting and collections.
  • PayPal — available on request; get in touch before ordering.

VAT and invoices

Prices on the site are shown excluding VAT, because most of our customers are garages and trade workshops. VAT at 20% is added at checkout, so you always see the exact total before you pay, and a VAT invoice is issued with every order.

Is my payment secure?

Yes. Card payments and Klarna are handled by Stripe, a PCI DSS Level 1 certified provider, over an encrypted connection. Card details are entered directly into Stripe’s hosted fields — ControlUnits never receives or stores your full card number, and we don’t keep card details on file unless you choose to save a card to your account.

Frequently asked questions

Can I really pay after the repair?

Yes, for repair services. Choose Payment After Repair at checkout and pay nothing upfront. We test and repair your unit, then contact you for payment before it ships back. Replacement units and on-site fitting are paid at checkout or on collection.

Which cards do you accept?

Visa, Mastercard, American Express and Maestro, plus Apple Pay and Google Pay on supported devices. All card payments run through Stripe with 3-D Secure authentication.

Do your prices include VAT?

No — prices are shown excluding VAT. VAT at 20% is added at checkout and shown separately, and you receive a VAT invoice with your order.

Can I pay by card over the phone?

Yes. Call 01884 798090 during opening hours (Monday–Friday, 09:00–17:30) and our team will take payment, or send you a secure payment link instead.

Do you offer instalments?

Yes, through Klarna at checkout — pay later or split the cost into instalments. Approval and terms are set by Klarna at the time of purchase.
