Royal Mail 1st Class: What Is It and How Does It Boost Your Shipping Speed?
Royal Mail 1st Class is among the fastest shipping options in the UK, helping you send letters, large envelopes, and small packages. Its delivery timeframe is one working day, which means you can get these mailpieces delivered the next day from when you drop off the items.
You can mail items weighing up to 20 kg using this Royal Mail service. The cost is higher than some other services because of its exceptional speed. However, it does not come with tracking and you must purchase Signed For 1st Class to get proof of delivery.
The best part is it’s not as expensive as you may think! One of our clients at PostGrid, an insurance company, wanted a quick solution to send compliance letters to all policyholders.
They used to send mail via a private courier earlier, after their staff spent days compiling the documents. Hence, switching to something better was the need of the hour! And the first thing they wanted to learn was—How fast is Royal Mail 1st Class.
This blog answers this question in-depth and discusses how to send your shipments to clients and others speedily and hassle-free.
Key Takeaways:
- Royal Mail 1st Class allows users to send important documents, letters, transactional statements, etc., the very next day. It also helps send small parcels weighing no more than 20 kg.
- One can purchase add-on services with 1st Class Mail like getting proof of delivery and tracking. These solutions ensure you see where your items are within the postal system once you send them and can get the recipient’s signature.
- Some users who wish to pay less and don’t need to send something as urgently can use 2nd Class Mail, which helps deliver items within two to three business days. There is also an option called Royal Mail same-day, allowing you to ship something in the morning and have it delivered by evening.
- You can use PostGrid’s direct mail services to send direct mail items on time. It offers a 2-business-day SLA, letting you get the mailers out of the door in no time.
What is the Royal Mail 1st Class Service and How Much Does the Stamp Cost?
Featured snippet: Royal Mail 1st Class is a postal shipping service that allows users to deliver their items the next working day, including Saturdays. It helps individuals and businesses urgently ship marketing, transactional, and compliance items at affordable rates.

Our client wanted to learn about the Royal Mail 1st Class post delivery time frame, and we gladly informed them about it! Keep reading below…
How Long Does the Royal Mail 1st Class Take?
1st Class Mail helps deliver your letters and parcels to all mailing locations the next business day, including Saturdays. But the Post Office will complete deliveries on Monday if you drop them off in the mailbox after the cut-off time on Fridays or Saturdays.
Hence, be careful about the cut-off times at your local Post Office to avail yourself of the next-day delivery feature.
Also, bad weather conditions, highway construction, or road accidents can cause delays. Ask your carrier or the clerk at the nearest postal outlet—What are the Royal Mail 1st Class delivery times during such days?
Royal Mail delivers your mailers the next business day on almost all days in most places. But it is best to enquire about shipping to rural destinations to ensure it does not return your mail.
Our client wanted to send compliance letters to all policyholders in London, so it went smoothly for them! Most envelopes they sent via 1st Class Royal Mail arrived early the next working day, facilitating the process and helping them achieve their goals.
Moreover, automating the print and mail processes through PostGrid’s direct mail API helped them be quick and efficient.
But Wait, Royal Mail 1st Class Offers More Features!
The 1st Class mailing option provides users with additional features.
It offers Compensation Coverage of up to £20
It allows you to protect your documents and ensure the Post Office covers the losses if they lose or misplace the mailers.
Standard Prices for All UK Addresses
The Royal Mail 1st Class service lets you send your shipments to any state or city in the UK for the same rates, irrespective of the mailing distance. The postage depends on the weight of the items. Find the table at the end of this section to learn more!

You can use 1st Class Royal Mail to send lightweight and heavyweight articles weighing up to 20kg. It is an affordable way to transport your parcels or multiple-paged letters via the Post.
Stamp Prices Start at £1.35 Only
Isn’t it a steal deal? You can mail your letters starting at only £1.35, making 1st Class Mail one of the most affordable options for everyone.

Don’t Forget the Signed-For Postal Option
Once our client knew the answer to “How long does the Royal Mail 1st class take?” we discussed the Signed-For option.
It is an add-on for 1st and 2nd-class mailing services for users who want the carrier to take the recipient’s signature on delivery. This feature helps senders ensure the item has reached the right hands.
The Royal Mail Signed-For 1st Class service is slightly expensive, starting at £2.60. It also provides compensation cover of up to £50.
The Signed-For service helps you get online delivery confirmation and a copy of the recipient’s signature. Please note that it does not affect the mailing speed or other features Royal Mail 1st Class offers!
You Can Also Opt For
Royal Mail lets you choose among mailing services apart from 1st Class. They include
2nd Class Mail
Users who don’t need to send items the next day can choose 2nd Class Mail. It ensures your mailers reach their destinations within two to three business days. Hence, it is more affordable than Royal Mail, 1st Class, with prices starting from £0.75.
Its features include
- Compensation coverage of up to £20,
- Same rates for all UK addresses, and
- Optional Signed-For add-on.
Royal Mail Same-Day
Our account manager educated our client on more urgent shipping options in the UK, like Royal Mail Same-Day. It helps users send items on the same working day. Imagine you visit the Post Office to lodge something on a Wednesday morning: the postal employees can process and deliver it by evening.
Hence, the answer to “Is Royal Mail 1st class next day,” is no! The Post Office offers a separate shipping service for urgent, same-day mailings at a higher cost.
It has many benefits, like
- Email delivery confirmation
- End-to-end tracking
- No weight restrictions
- 24 x 7, 365 days availability, and
- Automatic compensations for losses or damage of up to £2,500.
Royal Mail Tracked 24 and 48
The Tracked 24 option is similar to Royal Mail, 1st Class—only faster. It lets you get your shipments to their destinations within 24 hours. Often, many in-city mailers arrive on the same working day.
Its prices start at £3.30. You can track your items until the delivery point.
Tracked 48 has similar benefits but aims to deliver your items within 48 hours or two to three business days. Its rates start at £2.70.
You can use these options to send tracked shipments when you want to guarantee your shipments reach the correct items with evidence. Also, use Special Delivery Guaranteed by 9 am and 1 pm if you want to ship something urgently. This guaranteed delivery option is available at every Post Office branch and online for customers.
Special Delivery Guaranteed by 1 pm and 9 am is available for 1st Class. Buy online the 1st Class stamps required to upgrade to it.
