The best way to prepare a UK mailroom for Christmas is to sort supplies, postage credit and posting routines before the rush starts, not during it. Order ink and labels for your machine in October, top up your meter with a buffer, and check Royal Mail's official Christmas posting page for this year's last recommended posting dates. Mailmark franking prices did not change on 5 October 2026, so your budget stays predictable.
Why the Christmas peak catches mailrooms out
Between late October and mid-December, most businesses send more than usual: seasonal invoices, customer cards, year-end statements, supplier thank-yous and marketing letters. A franking machine that comfortably handles 200 items a week in September may be asked to print 600 in December. That is when a nearly empty ink cartridge, a missing roll of labels or a dry postage balance turns into a lost posting day.
The good news is that almost every festive mailroom problem is predictable, and therefore cheap to prevent. The checklist below takes about an hour and can be done this week.
Step 1: Check your ink and labels now
Estimate your December volume, compare it with the yield of the cartridge in your machine, and buy a spare before you need it. Our guide to franking ink cartridge yields shows how to work out how many impressions you really get, and why cartridges can stop with ink still inside.
If you print onto labels for larger cards, boxes or bulky envelopes, stock those too. Our explainer on franking machine labels covers when a label beats printing directly on the envelope. Then find your model on the Pitney Bowes, Neopost / Quadient, FP Mailing or Frama collection to order the correct consumables.
Step 2: Do a quick print quality test
Print ten test impressions on the envelopes you plan to use. Under Mailmark, a faint or streaky impression can cause delays or surcharges, and a rushed December is the worst time to discover a blocked printhead. If anything looks patchy, follow our guide to fixing faded or streaky franking before the volume arrives.
Step 3: Top up postage credit with a buffer
Franking credit is prepaid postage, so a low balance stops you franking mail immediately. Work out a realistic peak-week spend, add a buffer, and top up before it is urgent. Our guide to postage credit top-ups explains how much credit a mailroom should hold and how to set low balance warnings.
Step 4: Know your 2026 franked prices
Current Mailmark franked prices, unchanged from 7 April 2026 and unchanged again on 5 October 2026, are 88p for a 2nd Class letter and £1.77 for a 1st Class letter (up to 100g). Large letters (up to 100g) are £1.52 for 2nd Class and £2.86 for 1st Class. That is 3p less than the stamp price on standard letters, and 44p less on a 1st Class large letter. You can check the full table on the Mailcoms franking prices page, and see how we compare methods in franking machine vs stamps.
Step 5: Watch out for festive envelope sizes
Greeting cards, boxed items and padded envelopes often tip mail over the letter limit into large letter pricing. Measure a sample of your seasonal mail against Royal Mail's size limits, using our letter or large letter size guide. If you are restocking, choose the right type from our envelopes collection, and read self-seal versus gummed envelopes if you are unsure which suits your machine.
Step 6: Post early and hand over correctly
Franked mail must be posted on the date shown in the impression, so do not frank a week's worth in advance. Sort by class and format, and follow the handover rules in our guide to posting franked mail. Royal Mail publishes its Christmas last recommended posting dates on its official Christmas page each year, so check there for the confirmed dates and plan to post earlier than the deadline rather than on it.
If you send overseas cards or orders, allow extra time and read franking international mail for zones and customs forms.
Step 7: Keep the mailroom greener
Peak season creates waste: spare cartridges, offcuts and oversized packaging. Send empty cartridges for reuse through our ink resetting, refilling and recycling service, and use envelopes sized to the contents. More ideas are in our guide to sustainable mailing for small businesses.
Need a machine, not just supplies?
If your current machine is struggling with peak volumes, or is one of the older models no longer accepted for Mailmark, our sister company Mailcoms can advise on buying, leasing and servicing franking machines. Green Franking supplies the ink, labels and consumables to keep it running.
Frequently asked questions
When should I order franking supplies for Christmas?
Order in October, ideally with one spare ink cartridge and enough labels for your busiest week. Delivery delays and stock shortages are more likely closer to December.
Have Mailmark franking prices changed for Christmas 2026?
No. Mailmark franking prices were unchanged on 5 October 2026. A 2nd Class letter is 88p and a 1st Class letter is £1.77, both up to 100g.
What are Royal Mail's Christmas 2026 last posting dates?
Royal Mail publishes the confirmed dates on its official Christmas page. Check there for this year's dates and post earlier than the stated deadline rather than on it.
Can I frank cards in advance?
No. Franked mail should be posted on the date printed in the impression, so frank each day's post on the day you hand it over.
How much postage credit should I hold in December?
Estimate your busiest week's spend, then add a buffer so a delayed top-up does not stop you posting. Set a low balance warning on your meter where it is available.
Can I recycle empty franking ink cartridges?
Yes. Green Franking offers an ink resetting, refilling and recycling service, which reduces waste and can lower your cost per impression.
