How we calculate service charges
We calculate your service charge contribution by using the rateable values of:
- your property
 - the block and estate
 - the total cost of the service
 
About the rateable value
The rateable value (RV) is the floor space of the property, which was set by the government. This means a 3 bedroom property will have a higher RV than a 2 bedroom property as it's expected to be bigger.
Example calculation
An example of how the service charge would be calculated based on the following RVs:
- Flat RV: 213
 - Block RV: 3384
 - Estate RV: 121318
 
Estate charge
If the estate caretaking charge to your estate was £13,595.71, your contribution would be calculated like this:
213 (flat RV) / 121318 (estate RV) x £13,595.71 cost = £23.87 (your contribution)
Block charge
If the block repair charge to your block was £813.62, your contribution would be calculated like this:
213 (flat RV) / 3384 (block RV) x £813.62 cost = £51.21 (your contribution)
There may be some exceptions. Contact the Home Ownership Service if you have any queries about the calculations.
