How the Annual Increase Is Calculated
Since July 2023, all pitch fee reviews in England and Wales must use the Consumer Price Index (CPI) to calculate any inflationary increase. Before that, the Retail Price Index (RPI) was used, which tended to produce higher figures.
This change was introduced through the Mobile Homes (Pitch Fees) Act 2023, and it was designed to keep annual increases more predictable and manageable for residents. CPI is generally lower than RPI, so most Park Home owners will see smaller year-on-year rises than they would have under the old system.
The park owner can't simply choose whichever index suits them. If they use RPI in their calculations after July 2023, the entire review is invalid and you don't have to pay the proposed increase. You should, however, continue paying your existing fee until the matter is resolved.
On top of the CPI adjustment, a park owner may also factor in costs for genuine site improvements. But they'll need to have consulted with residents beforehand, giving at least 28 days' written notice of the proposed works and explaining how the improvements will affect the fee.
