Council tax empty property premium

The London Borough of Harrow charges a premium on long-term empty dwellings. These are homes that have been unoccupied and unfurnished for at least one year. The one-year period starts from the date the property first became empty. It does not restart if there is a change of owner.   There is no right of appeal in relation to the level of the premium determined by London Borough of Harrow, but you may submit an appeal if you believe that you are not liable for the Council Tax or the premium has been applied incorrectly, for example. The premium is in addition to the usual Council Tax charge.

The charge was agreed by the Council and introduced to encourage bringing properties back into use. For help to bring empty properties back into use, and to carry out repairs, please view the Empty Properties page.

The table below sets out the premium applied to long term empty and unfurnished properties:

Long term empty property criteria giving rise to additional Council Tax premiums Premium
Properties which have remained empty and unfurnished for at least 1 year 100%
Properties which have remained empty and unfurnished for less than 5 years 100%
Properties which have remained empty and unfurnished for between 5 and 10 years 200%
Properties which have remained empty and unfurnished for at least 10 years 300%

The effect of the premium is that for properties that have remained empty and unfurnished for at least 1 year, the Council Tax payable will be 200% of the Council Tax set for the property valuation band concerned, 300% where properties have remained empty and unfurnished for between 5 and 10 years and 400% where properties have remained empty and unfurnished for at least 10 years.

From 1st April 2025, a premium of 100% will also become payable for properties where there is no resident and which are substantially furnished.  That will mean that the Council Tax payable for such properties will be 200% of the Council Tax amount set for the valuation band of the property concerned

  • Notification to your mortgage company that you are now resident at your Harrow Council address;
  • Notification of changing your buy to let mortgage to an in-residence mortgage; 
  • Removal firm receipts. 

Utility bills will not generally be acceptable as evidence of residency.

This is now your main home

If you have more than one home, we will need to determine where your main residence is located. We may ask you some of the following questions to determine your place of residence for Council Tax purposes:   

  • Where are your family resident? 
  • Where do your children go to school?  
  • Where are the majority of your possessions kept? 
  • Do you normally rent out this property? If so, is this is a period in between tenancies? You will not be entitled to a single person discount unless you can show evidence that you moved to this address after the former tenant(s) left. Forms of evidence include: removal receipts, notifications to your insurance company and/or mortgage company. 
  • Where are you registered for your GP and / or dentist?  
  • What security of tenure do you hold in this property?   (e.g., do you own or rent it)
  • How much time do you spend at this property on average in a week? (e.g., 2 days, etc)
  • Where are you registered for voting purposes?  
  • Does this property comprise your main home for the purpose of your buildings and contents home insurance? 
  • Do you have a buy to let mortgage?
  • Where are you registered for tax purposes?
  • Where are you registered for voting purposes?

After considering the above, Harrow Council will form an opinion whether your sole or main residence is elsewhere. Should you do not agree, you will need to provide supporting evidence. Examples of evidence include the following: 

  • Your closing Council Tax bill for your former place of residence showing your dates of residency at that place; 
  • Notification to your mortgage company that you are now resident at your Harrow Council  address;
  • Notification of changing your buy to let mortgage to an in-residence mortgage 
  • Removal firm receipts

If you are, or were, working abroad, your Harrow Council address will generally be considered your sole or main residence if you intend to return to that property.

The property is empty and unfurnished

There is generally no reduction for empty furnished or unfurnished properties in Harrow. However, in some circumstances, the reason for a property being unoccupied may mean that it could exempt you from payment of Council Tax.  

For further details please see Council Tax Discounts and Exemptions

You are required to live elsewhere as part of your employment

If you are a member of the armed services required to live elsewhere as a result of that service, you will not be subject to the premium charge. This may include armed forces provided accommodation or other accommodation that you are required to reside in for the purposes of your service. You will need to provide confirmation of this requirement. For further details see UK Armed Forces Discounts.

If you are contractually required to live elsewhere as part of your employment, then you will need to provide a copy of your employment contract.  You will not be subject to a premium charge if your supporting evidence confirms this. Please use the following link to submit your evidence for consideration:

There is a planning restriction in place

Regulations provide that where occupation is restricted for a continuous period of at least 28 days, the premium charge will not apply. If other planning restrictions apply which prevent your occupation, you may be entitled to an exemption from the premium charge also.
Evidence of either of the above must be provided for us to consider your request for an exemption from the premium charge. 

Please use the following link to submit your evidence for consideration.

This property is an annexe to a main property

An unoccupied annexe may qualify you for an exemption from a premium charge.

For further details see Council Tax Exemptions for Annexes

Any other reason

If none of the above conditions apply, but you are of the opinion that you should not be liable for the premium, please submit details of this in writing with any supporting evidence to Harrow Council in the first instance.

Please note that if you disagree with the Harrow Council determination to charge a premium on empty properties, is not grounds for an appeal.
