The price increase takes effect from 5 October 2026 and affects the following services: Access business economy, advertising mail, and large-volume commercial sorting tariffs. This follows an increase announced earlier in the year (April). Businesses that use these rates and book in before the price hike may not notice two pence, but across thousands of mailers, it adds up quickly.

Data Cleanse - Why clean data saves you money While you can't reduce the price per item, you can quickly and efficiently mitigate the risk of overspending and may even end up spending less while reaching more customers and clients. Clean up your data; it's a silent and slowly draining expense on every campaign you've ever run. Rather than fixating on the two pence incurred per letter, focus on sending letters to the right people and the right places.
Royal Mail Data Services estimated that some businesses may be haemorrhaging as much as 6% of their annual revenue in poor data alone; this is fuelled by large hubs of transient renters and companies falling into the “goneaway trap”. If you aren't regularly washing your lists against the National Change of Address (NCOA) file, your goneaway rate compounds every year, multiplying your wasted spend. When was the last time you truly audited your data lists?
Drop filler pages or switch paper Less is more in 2026. As attention spans shrink, the fight for attention grows more intense, and what better way to win that fight than to reduce the volume of fluff and filler in your content. It’s a win-win: less paper to print, better read-through rates, and a more financially savvy campaign.
Does someone notice you switching from 120 gsm to 100 gsm, or from 170 to 150? Small incremental cost savings that don’t harm your campaign, while also letting you avoid compromising your send volume; it may only save you a small amount of money, but it can offset the price increase and still give you a little extra on top. The larger the campaign, the larger the savings you could expect; around £100 on a small campaign of 300-500 letters.
You could save at least 64 pence per mailing by switching from large letter to standard letter (calculated as of 19th of August 2026 and based on second class rates). Reducing the size of your mailer to under 100g may be a challenge for some, but it could be a format change or the revision of a few pages of content for others but it has potentially huge savings for a business attached to them.
Switch to a dedicated mailing house The price increase will be fresh in your mind today, but come next month and the month after, it will just be another silent and invisible cost, eroding bottom lines and leeching time from your team. Franking machines, print, data lists, toner, printer servicing, the return suppressions, the team member who has to make sure they make it to the post box on time - all costs you incur on a daily basis but don’t see.
Mailing houses get better rates because of the volume they send, which they can pass on to you, the customer.
How much could these changes save me? Thousands, depending on volume. Better data eliminates your production waste, efficient mailing options further reduce your production costs, and then industry experts handling your mailing needs are the final piece of the puzzle that sees a two pence price increase weaponised to become a four to five figure saving for you and your business.
If the easiest option right now for you is to simply book in pre-price rise, then you have just a couple of weeks to secure your campaign; the cut-off will be 21st of September to book your Direct Mail campaign on the current rates.
