How long does 1st class letter royal mail take

According to Royal Mail's website, the estimated delivery times for 1st Class mail in the UK are:

• Monday to Saturday: 1-3 working days
• Sunday: Not delivered

Please note that these are estimated delivery times and may vary depending on various factors, such as:

• The time of posting: Letters posted later in the day may not be delivered until the next working day.
• The destination: Delivery times may be longer for rural areas or areas with limited postal services.
• Weather conditions: Inclement weather may cause delays in delivery.
• High volumes of mail: During peak periods, such as Christmas, delivery times may be longer due to increased volumes of mail.

It's also worth noting that Royal Mail aims to deliver 93% of 1st Class mail the next working day, but this is not a guaranteed service. If you need a guaranteed next-day delivery, you may want to consider using Royal Mail's Special Delivery service instead.
