Is franking the cheapest way to send a letter?

Franking your post will save your business between 6% and 12% compared with the cost of stamps – and even more if your machine is Mailmark-enabled.

If you’re looking for the cheapest way to send post, then you should think about using a franking machine.

A franking machine measures your postage costs more accurately than humans, as well as being time efficient. Above all, your post qualifies for lower postage costs than buying stamps because you are doing some of the post office's work for them.

This article contains everything you need to know about cheap postage solutions for your business. Scroll down to find out how much you could be saving, and let us know what you need to get free franking machine quotes.


Is franking the cheapest way to send post for your business?

Depending on your specific business, the answer is yes or no. So there's a few costs to consider.

However, most businesses sending over 80 items of post every week will definitely save money in the long run.

Saving your business money is one of the best franking machine benefits. Franking machine postage rates are set between 2% and 15% lower than stamped postage prices. You will save at least 11p on the cost of posting a standard letter First Class, and 8p or more on Second Class postage.

With the above in mind, you could save up to £2,761 per year on First Class postage costs or £2,008 on Second Class if your business sends 100 items of post each working day.

How much does a franking machine cost?

A mid-range franking machine will cost around £1,500 to buy, plus the cost of ink cartridges and other maintenance bits. So, taking the example above, where a company sends around 1,000 letters each month with savings of nearly £2,800 annually, a franking machine will pay for itself within roughly two years.

For a top of the range model, built to process thousands of letters an hour, you can pay up to £20,000. Of course, the savings will scale according to the length of time you'll keep the machine and the volume of post your company sends.

If you’d prefer to spread the cost of a franking machine rather than pay a lump sum upfront, there are plenty of suppliers who give the option to rent or lease a franking machine.

Rental prices start from as little as £16 per month — though the price will vary depending on the volume of mail-outs. Typical contract lengths are between 12 months and five years, with longer contracts offering lower monthly rates.

Getting up and running with a franking machine

Step 1: Choosing a supplier

It’s essential that your franking machine is Royal Mail approved, so the first step is to choose a legitimate supplier. If you’d like some help, fill in the form at the top of the page and we’ll match you with the most suitable suppliers for your business.

Step 2: Applying for a license

Once you have your franking machine, you’ll need to apply for a license before you can start sending mail. Not to worry, though – your provider can help you do this.

Step 3: Arranging credit

If you have a good idea of the volume of mail your business sends monthly, it pays to set up a direct debit credit account. Again, your provider will be able to help you do this.

Step 4: Starting mailing — how to post a franked letter in the UK

So you’ve got everything set up. But how do you actually go about posting your franked mail? Well, it’s no different to posting regular mail; you can either take it to the Post Office or arrange for it to be collected. To avoid additional charges, though, you need to ensure your post is sorted by class, size and destination, and that parcels are presented in mail bags.

Franking machine maintenance and running costs

Just like you would to your staff, you’ll need to look after your franking machine in order to keep it working at its best.

The advantage of renting or leasing a franking machine is that maintenance is usually included in the monthly fee. So if anything goes wrong with your machine, your provider will fix or replace it free of charge.

In addition to any maintenance costs, bear in mind there will also be running costs for:

  • Ink cartridges — £80-230 each
  • Labels — £15 (plus VAT) for 1,000
  • Self-sealing envelopes – £18 for 1,000
