Visible Change 1st Large Business Sheet is not the same as previously reported

Today at last I received a copy of the King Charles III 1st class Large Business Sheet which is due to have its philatelic distribution on 20 March.  (There is no first day of issue for business sheets.)

I should have realised, from the Royal Mail trade publicity about this and the booklets, that we might be in for a surprise and so we are.  

The clue is in the words 'visible change' because this has the new Relay UK phone number for Deaf, hearing or speech impaired users, rather than the textphone number.  Consequently this is a quite different printing to the one previously reported.  The other was printed in 2024 and coded M24L, the new one in 2026 and coded M26L.

King Charles III 1st class Large Business Sheet coded M24, the printing is much less clear than on the M26L. This image has been digitally enhanced and the M24L can just about be seen.

King Charles III 1st class Large Business Sheet coded M24L printed in 2024 and found in November 2025.

The new printing is much clearer - M26L MBIL.

King Charles III 1st class Large Business Sheet coded M26L with first day of philatelic availability 26 March 2026.

M26L examples for sale -
I asked for expressions of interest for the 1st Large business sheet stamp when it arrived.  Now that we have yet another new one, I feel it best to ask again.

So please email and tell me how many of the M26L you would like; they will be only a little over cost plus postage.  

Also as we have a definite first day of (philatelic) availability of this one, please email if you would like a single M26L on first day cover with appropriate postmark (Windsor permanent will probably be used if any are wanted.)

As for the M24L version, it is likely to be very scarce with most examples I suspect being sold through Royal Mail's website to business customers.  I know that many post office branches are still holding the Machin version and won't have ordered any more.  They won't get an automatic distribution of even the M26L version but it seems more than likely that Royal Mail will want this distributed when needed as it has current information on it.

All copies of the M24L 1st Large have  now been sold or reserved, as have most of the other new business sheet stamps.  The first batch of orders was posted today.  Others, mainly for people who also want booklet stamps, should be posted week commencing 13 April. 

I will contact my correspondent of this and ask if he would like to dispose of any.   Please email if you would like any of these (how many).  No obligation of course as I don't know what price I shall have to charge.  But the M24L version should be included in the Gibbons Concise Catalogue as the primary stamp with the subsequent versions in the usual table.

UPDATE  - I've been asked about the other two values of Business Sheets - 1st class and 2nd class.  I had not planned to get these as I didn't have the imagination to realise that the Visible Change would be for M26L stamps as I expect these two values to be also.  
Updated update: I've been told that the 1st class business sheet VC is 2025 2nd class VC is 2026. I think that still makes them both new.

1st class M25L MBIL Business Sheet

2nd class M26L MBIL Business Sheet

 

So if you wish to have these, please also say so, although if I cannot sell sufficient at a 'close to face' price, I will have to charge more to cover the ones that I have to sell for postage.
And the FDC would be for three stamps!

UPDATE 24 March: I've been told that the 1st Large booklet did not arrive at Tallents House until Friday 20th, so distribution by Royal Mail will be delayed.

There's never a dull moment, is there?  I'll be posting images of the new booklet stamps in a separate post when I have them all.

Update on the 1st Large Business Sheet - and other new products

The King Charles 1st class Large Business Sheet - missing from the original printings of business sheets and first reported here - will have an official distribution on 20 March - along with several other 'new' products which have the new font (and presumably the new crown).

Royal Mail have said that these will have a 'first day of (philatelic) availability' although some have been available in Post Offices and other retailers over recent months.

These are not all available yet from Tallents House, so there is no point in phoning for them!

Full list - product codes will be provided later:

Business Sheets:  1st class, 2nd class, and 1st class Large

Booklets:  4 x 1st, 4 x 1st Large, 8 x 2nd. 
 

More details when available.

UPDATE 3 February

Royal Mail have said that this is simply a font change, but Robert writes:

"Seems likely to me the Textphone info is the real visible change here as most of these items have already appeared with the 2025 Rebrand." 

As John H confirmed:

"the Textphone info was present on the 8x Christmas booklets, but dropped on the 4x. " 

Here is an earlier 2nd class booklet, followed by the Christmas 1st class x4 and x8 without the Textphone line showing all the changes. (Thanks to Robert and John H).

Original back cover showing dimensions for which the stamps are valid, phone & textphone numbers and website

Book of 8 Christmas cover showing phone & textphone numbers, website, QR code for last posting dates and URL for postcode finder

Book of 4 Christmas cover which has dropped the textphone number and provided the Relay UK number for deaf, hearing or speech impaired users.  The phone number and website are retained, and the QR code for last posting dates and URL for postcode finder on the book of 8 continue.

If that's the only change it remains to be seen whether Stanley Gibbons will identify these by a separate number or sub-number.  But As there is much more too it than simply the removal of the Textphone number, it seems that this should qualify for a new catalogue sub-number.  

Whether the Validity (size) details return on the post-Christmas definitive booklets produced in 2026 remains to be seen.

Back in 2019 I reported that when the Printer's imprint was removed and the FSC logo was added these were both identified in the Concise.  But when the phone numbers changed from 0845 to 0345 this was consigned to a footnote, even though collectors usually wanted both.  So because of this inconsistency, we will have to wait and see!  I think the difference is enough to warrant a new catalogue number.

UPDATE 15 February

Royal Mail have started delivering these new products to dealers with standing orders, and from this we can see that the text panel is the same as the (later) 4 x 1st Christmas while the Validity text returns to normal.   Here's the 2nd class book of 8, with cylinder numbers.  (Click on any image to see an enlarged version.)

Surprise new service and prices from 1 January 2026

Unexpectedly - and not announced to business users via the usual email or letter - Royal Mail have issued another 'Our Prices' leaflet from 5 January 2026. (Download it here.)

Strictly speaking there are no tariff changes, ie no prices have changed, but some services have changed including the elimination of 'International Signed".  Only International Tracked and Signed and International Tracked remain.

Summary

International Tracked and Signed is now for Documents only, and only up to 750g (ie no parcel rates).

International Tracked is for Goods, including gifts, and Documents may be sent but a Customs Declaration must be completed.  There is no (basic) letter rate; the cheapest option is for 100g Large Letters.

Printed Papers have been moved to a new section and include rates for International Tracked, International Standard (basic airmail) for which there is also no basic latter rate (minimum price for 250g is £8.95 to Europe), and ( listed in that order) International Tracked and Signed (again, no letter rates so minimum price £14.25) but including weight options for 1kg to 5kg.

I'm working from a pdf rather than hard copy, which makes comparison difficult, but I could almost believe there are copy & paste errors in this.  Why no Small Parcel rates for ITS unless they are printed papers?  Why no Large Letter rates for printed papers under 250g?

I'll leave this for readers to pursue safe in the knowledge that only the dealers and collector-sellers will be affected!

Postage Value of Older Stamps including Post and Go - October 2025 version.

This post brings previous tables up to date with the postage rates effective from 6 October 2025.

The tables are included primarily to explain the stamps used on cover, because they show that, for example, a stamp originally issued as a 30p Europe 20g stamp would later be valid for 100g and with a value of £1 in 2015 and £2.20 in 2023!

Remember that the International Rate stamps were all valid at the rates shown for inland postage, just as the 2nd, 1st, Large, Signed For, and Special Delivery stamps were all valid for inland services in addition to those shown and on international mail.

Now, of course, the old Machin and Country definitives without barcodes are no longer valid but the Post and Go stamps are as are the commemorative stamps, so the tables are still relevant for new use as well as for for Postal History purposes.

The E stamp was issued from January 1999-2004, and paid the Europe 20g rate.  This was 30p when issued and the cost but also the franking value increased periodically:

October 1999 (34p), April 2000 (36p), July 2001 (37p), May 2003 (38p), April 2004 (40p), April 2005 (42p), April 2006 (44p), April 2007 (48p).

Christmas and Commemorative stamps remain valid.

'E'- denominated stamp - still valid at a value of £3.40

 

Europe 20g/Worldwide 10g Post and Go stamp now valid worldwide for 100 g.

* With effect from 1 September 2020 a combined Euro 100g/World 20g Post & Go stamp was issued, priced at £1.70.
§ On the same date the World 100g stamp was replaced by two stamps: World 100g Zone 1-3 is sold for £2.50, and World 100g Zone 2 is £2.55.
 
On 1 January 2021 the pricing for all world zones was standardised, although that for large letters over 100g varied.   The Post and Go range was then consolidated to include airmail Large Letter stamps. 

Inland premium services

Note that some of the rates were in effect before the stamps were issued, and some new stamps were issued at old rates before tariff increases.

Postal rates 7 April 2025 - basic airmail rate and 1st Large Letter see biggest increases.

By now many of you will have seen news of Royal Mail's next price increases on stamp/Postcrossing forums or social media, but as yet there is no press release so we don't know what weasley words Royal Mail will use this time to justify some quite large rises.

Press Release added 2106 7 March:

Royal Mail carefully considers prices, balancing affordability with the increasing cost of delivering mail. 

Letter volumes have fallen from 20 billion a year in 2004/5 to 6.7 billion in 2023/4, and could fall to 4
billion a year within the next four years. Over the same period, the number of addresses has risen by four million meaning the cost of each delivery continues to rise.

Nick Landon, Chief Commercial Officer at Royal Mail said: “We always consider price changes very
carefully but the cost of delivering mail continues to increase. A complex and extensive network of trucks, planes and 85,000 posties are needed to ensure we can deliver across the country for just 87p.

“Ofcom has recognised that reform is urgently needed to protect the one-price-goes-anywhere Universal
Service which requires Royal Mail to deliver letters to around 32 million UK addresses six days a week.
Reform will allow continued investment in the modernisation and transformation of the business to
provide a more financially sustainable service.” 

Ends

======================================

The new rate chart can be downloaded here.  New prices in bold, unchanged rates in italics, reduced price in red.  The differential between 2nd and 1st for a 100g Large Letter rises from £1.05 to £1.60 (and 12 months ago it was only 55p!). 

The 2nd class rate for 100-250g is reduced to below the April 2024 rate and is now only 15p more than the April 2023 rate, presumably reflecting market forces.  If it doesn't matter that 2nd class will only be delivered on alternate days this seems to be a much better option than 1st class. 

	1st		2nd
Letter	1.70	1.65	0.87	0.85
Large Letter – 100g	3.15	2.60	1.55	1.55
- 250g	3.60	3.50	2.00	2.10
- 500g	3.60	3.50	2.40	2.50
- 750g	3.60	3.50	2.70	2.70
Small Parcel 2kg	4.99	4.79	3.90	3.75
Medium Parcel 2kg	7.19	6.99	6.29	6.15
- 10kg	8.99	8.69	7.89	7.65
- 20kg	13.69	13.19	11.89	11.55

Special Delivery rates are also increased.  The 100g rate rises by 40p from £8.35 to £8.75, the 500g rate by 50p to £9.85. Increases for delivery by 9am are between 11% and 21%.

UK Tracked rates see minor increases.  The basic 1st class Large Letter rate is again raised by 10p to £3.70, the Small Parcel rate by 16p to £5.15.  The 2nd class rate remains at £2.80 for 750g the Small Parcel is up by 10p to £4.05. 

UK Signed is up from £3.35 to £3.60 1st class and from £2.55 to £2.77 for 2nd class.

International rates.   The basic letter rates are increased, but not the Large Letter and Parcel rates.  The airmail rate which increased in October from £2.50 to £2.80 goes up a further 40p to £3.20, and the surface rate is up 50p to £3.10.  This is bad news for Postcrossers!  It will bring a new barcoded definitive of £3.20; however creating either rate from special stamp issues is going to be more difficult especially with the size of new barcoded stamps to make up any shortfall.

A quick look at Premium services - International Tracked, Signed, and Tracked & Signed see changes of up to 15% but not at all levels.

The stamps

Prices for Large Letter Airmail stamps have remained static since January 2021, so it should be no surprise that they are now higher and will require new stamps.

Airmail rate stamps issued 27 March 2025: £3.20 spruce green (100g letter rate)
£3.50 Wood Brown (100g Large Letter Europe)
£4.20 Bright Blue (100g Large Letter Worldwide).

Technical details are the same as for other definitive stamps: printed in gravure on self-adhesive sheets of 25 by Cartor Security Printers.  The security codes are MAIL M25L.  The printing dates are 13, 14 & 15th January 2025 respectively (lowest to highest).

Christmas 2021 forgery may be from a different producer to most

I was shown a new forgery this week which does not have all the hallmarks of the usual Chinese forgery productions.

It was far glossier than most, and the perforations were not up to the usual high (matching) standard.  It's the 2021 1st class Large Christmas stamp.  Now forgeries of the Machins were already better than this, so it's not a case of all the older forgeries not being of high standard.

This isn't a great photo but it was the best I could manage in a church hall!

Forged 1st class large Christmas 2021 stamp

Has anybody seen any others like this?

UPDATE 15 July.

My thanks to Lew who has sent this image of a block of 4 that he bought.  He notes that the barcodes are identical and the scan is PC: 00000000000000  - just like the RM publicity photos.

Postage Value of older stamps including Post and Go.

I overlooked updating this information at the start of 2022; the post will later incorporate the 2023 tariff.

The tables are included primarily to explain the stamps used on cover, because they show that, for example, a stamp originally issued as a Europe 20g stamp is now valid for 100g and has a current value of £1.85.  So a letter to Europe much heavier than 20g can now use that stamp - up to 100g.  

Likewise,  Worldwide 40g and 60g stamps are now worth £2.55 and can be used anywhere in the world up to 100g.

‡ I've now added the E stamp, issued from January 1999-2004, which is the equivalent of the Europe 20g rate.  This was 30p when issued and the cost but also the franking value increased periodically:

October 1999 (34p), April 2000 (36p), July 2001 (37p), May 2003 (38p), April 2004 (40p), April 2005 (42p), April 2006 (44p), April 2007 (48p), April 2009 - as below.

 

The Worldwide Postcard stamp (shown) issued in 2004 was originally sold at 43p. The cost and the franking value increased - April 2005 (47p), April 2006 (50p), April 2007 (54p), April 2008 (56p), April 2009 as shown in the Worldwide 10g column below.

* With effect from 1 September 2020 a combined Euro 100g/World 20g Post & Go stamp was issued, priced at £1.70.
§ On the same date the World 100g stamp was replaced by two stamps: World 100g Zone 1-3 is sold for £2.50, and World 100g Zone 2 is £2.55.
 
On 1 January 2021 the pricing for all world zones was standardised, although that for large letters over 100g varied.   The Post and Go range was then consolidated to include airmail Large Letter stamps.


Inland premium services


Note that some of the rates were in effect before the stamps were issued, and some new stamps were issued at old rates before tariff increases.

* Royal Mail Signed For stamps were issued 27 March 2013, replacing Recorded Signed For, but were sold at old rates until 2 April.

  

UPDATE 25 November: SD & RMSF stamps were withdrawn from sale at post offices on 31 October 2021, and also from Royal Mail's online shop.  They continue to be valid for postage at current ratesuntil invalidated on 31 July 2023.

I hope readers find this useful.  It is probably worth reminding everybody that these are also all valid at the rates shown for inland postage, just as the 2nd, 1st, Large, Signed For, and Special Delivery stamps are all valid for services other than those shown and on inland and international mail but will cease to be so from 1 August 2023.
