These are the simple steps to start using reply envelopes

Step 1

Choose the Royal Mail Reply Service that you require. There are four services available from Royal Mail. These are Business Reply Standard, Business Reply PLUS, Freepost Standard and Freepost PLUS (Freepost means free to the person who posts the envelope, not to you). Business Reply Envelopes and Freepost Envelopes work in exactly the same way and you can use either design with your standard or plus licence. The Royal Mail PLUS service cost you less in postage, but is oONLY available for envelopes up to C5 size. Envelopes over this size have to be hand sorted, so must be sent using the Royal Mail STANDARD service. This includes C4 size envelopes which take a flat, unfolded A4 sheet.

Step 2

If you have not already got one, you'll need a Royal Mail licence. This is easily available and opens an account with Royal Mail to pay for the licence and postage that you will use. You will have to pay a deposit for the postage, but you only charged for postage on each envelope that is posted back to you, so there is no risk or waste.

What's the difference between the Royal Mail Business Reply Standard and Business Reply Plus licences?

The only difference between the Royal Mail Business Reply PLUS licence and the Royal Mail Business Reply STANDARD licence is that with the "PLUS" licence, Royal Mail charge you (currently) 6p LESS in postage. This is your 'reward' for using standard size machine sortable envelopes, such as our standard size DL or C5. The reason is that the 'Plus' service envelopes do not need to be sorted by hand, which saves Royal Mail money, which they pass on to you.


Business Reply or Freepost envelopes larger than C5 size (162mm x 229mm) CANNOT be used on the PLUS licence as these have to be hand sorted. If you need to use C4 envelopes, make sure that you apply for the STANDARD licence. If not, always apply for the PLUS licence as this will save you money. Further details are available on the Royal Mail website.

See Royal Mail advice pages on Business Reply Plus or Business Reply Standard for more details.

Printed Royal Mail Business Reply Envelope and Royal Mail Freepost Envelope sizes

We print the most popular sizes of Royal Mail C6, DL, C5 and C4 Business Reply Envelopes or Freepost Envelopes.

  • C6 is 114mm x 162mm and takes A5 folded twice or A4 cross-folded.
  • DL is 110mm x 220mm and takes A4 folded into three. It is the standard business envelope size.
  • C5 is 162mm x 229mm and takes A5 flat or A4 folded once.
  • C4 is 324mm x 229mm and takes A4 flat. C4 envelopes are OK for Business Response Standard use but are not allowed by Royal Mail for Business Reply Plus, which is only for standard machine sortable sizes such as DL and C5. C4 envelopes have to be sorted by hand.

Does the exact address on my reply envelope matter?

Yes, it most certainly does. Every house and business in the UK has an entry into the Royal Mail Postal Address File (PAF). This is what the sorting machines use to identify your mail. It is vital that you use the EXACT address that is printed on your Royal Mail Business Repsonse Licence, otherwise Royal Mail will reject the proof of the envelope. (Don't worry, if they do, we will just find the correct address from the Royal Mail PAF file and re-submit the proof to Royal Mail- No extra charge - all part of the service).
If you are curious, you can look up your own correct postal address (or any other) here. Type the address into the search box. As you type, the search will narrow your options.

If you're looking for a common street name, you may need to provide more details, such as town or city to narrow your search down. When you see the address you are interested in, you can select it from the list.

Reply Paid Envelope artwork and layout

We create the reply paid envelope artwork and add the correct personalised barcode for you at no extra charge. No need for you to get the artwork from Royal Mail as ours is created by experts and is FREE. We then proof the reply paid envelope layout to you and once you confirm that you are happy with the proof, we submit the mandatory proof to Royal Mail on your behalf. Once they pass it, we print the envelopes and deliver to your home or office FREE of charge.

The Royal Mail Artwork generator is available on the Royal Mail Website and many people are tempted to use it. They mistakenly assume that the artwork it creates has then been passed by Royal Mail. This is NOT the case. You could type in any address, in any format and the automatic artwork generator would still create the (incorrect) artwork for you. ALL Business Response artwork HAS to be passed by Royal Mail before being printed. Failure to get it passed by the correct department risks a Royal Mail Postage SURCHARGE being applied to every envelope that is used. A very expensive mistake! Much safer to let our experts create the barcode and the reply paid envelope artwork for you and to submit the mandatory proof to the correct department at Royal Mail, on your behalf. There is no extra charge for this service.
