Royal mail first class how long

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

• Next Working Day (Monday to Saturday) for most of the UK
• 1-2 Working Days (Monday to Saturday) for some areas of the UK, including:
  • Northern Ireland
  • Scottish Highlands and Islands
  • Isle of Man
  • Channel Islands

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

• The time of posting
• The destination
• The type of mail (e.g. letter, parcel, etc.)
• Any unforeseen circumstances (e.g. bad weather, road closures, etc.)

It's also worth noting that Royal Mail aims to deliver 93% of First Class mail within 1 working day, but this is not a guaranteed service.
