Franking Machine Licences and Inspections: What UK Businesses Need to Know
A franking machine licence is supplied by your franking provider, not bought separately from Royal Mail, and it comes with obligations: keeping the machine loaded with current prices and having it inspected and maintained by a Royal Mail authorised provider. Get those two things right and your franked mail will be accepted without fuss. This guide explains how the licence, the provider and the inspections fit together, so you know what to ask for before you lease, buy or renew.
Who provides your franking licence?
According to Royal Mail's franking guidance, your licence is provided by your franking provider. In practice that means the company you lease or buy your machine from handles the paperwork and registers your machine, so you are not left to deal with it alone.
Royal Mail does not recommend one company over another. It publishes a list of franking service providers that are authorised to inspect, maintain or repair franking machines and to lease and sell them. If you are comparing suppliers, that list is the sensible place to start.
What does the licence require you to do?
Royal Mail states that anyone who already holds a licence to frank must keep their machine up to date with current prices and have it inspected and maintained under the Royal Mail Scheme for Franking Letters and Parcels. There are two practical duties here.
Keep the machine updated with current prices
Postage rates change, and your machine must reflect them. Our guides to the October 2026 Royal Mail price update and the April 2026 changes show why it pays to check each time rates move.
Use authorised providers for inspection and repair
Maintenance, inspection and repair must be carried out by Royal Mail authorised providers. That is separate from the everyday care you can do yourself, such as cleaning and changing consumables. Our franking machine maintenance checklist covers the routine jobs that sit alongside the formal inspections.
What is covered by your licence, and what is not?
Your licence and provider cover the machine itself, its registration and its inspections. The consumables you use day to day are a different matter. Ink cartridges and franking labels are what keep your mail moving between inspections, and you can choose where to buy them.
- Ink: find the right cartridge for your model with our guide to finding the right franking ink cartridge, then see whether original or compatible ink suits your mailroom.
- Labels: parcels and bulky items need labels, which we cover in when to use franking machine labels.
- Envelopes: choose stock your machine can handle, as explained in what envelopes you can use with a franking machine.
How is postage paid for?
Royal Mail lists Direct Debit, credit card and credit accounts with deferred payment terms as accepted ways to pay for franked postage. Exactly how credit reaches your machine depends on your provider and the model you use, so ask them to explain the process, including how and when you can check your balance, before you sign up.
Rules that affect your franked mail
Royal Mail asks that mail is separated by UK or international destination, then by product and class, to qualify for savings and avoid penalties. Franked mail can be posted up to 7 days after the meter impression is printed, so there is a little flexibility if collection is missed. The mark is printed directly onto the envelope, or onto a label for parcels. If you are weighing up whether franking suits your volumes, read franking vs stamps in 2026.
Common mistakes to avoid
Most franking problems come from small oversights rather than big failures. Letting a rate update slip means your machine prints the wrong value, and your postage no longer reflects Royal Mail's current prices. Mixing first and second class items, or UK and international mail, in one tray undermines the sorting Royal Mail expects. Running a cartridge until the print turns pale is another classic, and our guide to faded franking impressions shows how to spot the warning signs early.
It also helps to keep a spare cartridge and a few labels in the cupboard, so a sudden empty tank never holds up the afternoon post. A short weekly check of your supplies, your balance and the date on your machine takes a couple of minutes and prevents most last-minute scrambles.
Questions to ask a provider before you commit
- Is the licence arranged and registered on my behalf?
- Who carries out inspections, and are they Royal Mail authorised?
- How are rate changes applied to my machine?
- How do I pay for postage, and how do I check my balance?
- What happens to my machine and any remaining balance if I switch? Our guide to switching franking machines explains the consumables side.
- Which ink cartridges and labels does my model use?
