How to appeal a Companies House late filing penalty

7 min readBy CH Watch Team
Got hit with a £150 late filing penalty from Companies House? Don't panic - you can appeal it, and many appeals succeed. Here's exactly how to challenge the penalty, what excuses work, and how to prevent future penalties.

What exactly is the late filing penalty?

Companies House charges £150 for filing your annual accounts late - even by one day. It's automatic and harsh, but the good news is that legitimate appeals often succeed if you have valid grounds and file correctly.

Quick Action Required

You have just 3 months from the penalty date to appeal. Miss this deadline and you're stuck with the £150 charge.

Valid grounds for appeal

Companies House accepts appeals based on these grounds[1]:

Acceptable reasons include:

  • Serious illness of the person responsible for filing
  • Death of director/accountant during the filing period
  • Postal strikes or serious transport disruption
  • Fire, flood, or other natural disasters affecting your business
  • IT system failures (yours or your accountant's)
  • Companies House systems were down when you tried to file

What WON'T work as an excuse

Don't waste your time with these common excuses that Companies House routinely rejects:

  • Didn't receive the reminder emails (they're not legally required)
  • Your accountant let you down
  • You forgot or were too busy
  • Financial difficulties
  • Waiting for information from third parties
  • First-time mistake

How to appeal step-by-step

Download form AP01 from Companies House website (don't try email or phone appeals)
Complete form with exact company name and number, state grounds clearly with specific dates
Attach supporting evidence (medical certificates, proof of IT failures, etc.)
Submit within 3 months to: Companies House, Crown Way, Cardiff, CF14 3UZ or enquiries@companieshouse.gov.uk

What happens next?

Companies House typically responds within 4-6 weeks. They'll either:

  • Accept your appeal - The penalty is cancelled
  • Reject your appeal - You must pay the £150
  • Request more information - Respond quickly to avoid rejection

Preventing future penalties

The best strategy is never needing to appeal in the first place:

Prevention strategies:

Set up automatic calendar reminders 2 months before your filing deadline
Use CH Watch to monitor your company status and get alerts
File accounts early - don't wait until the last minute
Have backup contact details registered with Companies House
Keep your accountant's contact details updated

Pro Tip

Even if your appeal is rejected, it's often worth trying. Many companies successfully appeal penalties that initially seem hopeless - especially for IT failures or medical emergencies.
