Section 20 checker

Check whether works or a long-term contract need consultation under section 20 of the Landlord and Tenant Act 1985.

Use the largest percentage in any lease, not the average.

Enter the figures to see the result.

How this check works

Section 20 of the Landlord and Tenant Act 1985 requires consultation with leaseholders before major works that will cost any one leaseholder more than £250, and before a contract lasting over 12 months that will cost any one leaseholder more than £100 a year.

Enter the total cost and your flat's share from the lease. The checker works out what you would pay and whether that passes the limit, so you can see whether consultation is needed.

Government has proposed raising these limits, but that is not yet law.

Questions people ask

Where do I find my flat's share?
In your lease, usually in the service charge schedule, shown as a percentage or a fraction.
What if consultation wasn't carried out?
Recovery is usually capped at £250 per leaseholder for the works, unless the First-tier Tribunal agrees to dispense with the requirements.
