What our clients say

"When Homes England have asked for appraisals to justify the amount of grant, we can answer their query by providing the ProVal report."
- Saffer Cooper
"In my early career all appraisals and cashflows were done using spreadsheets — it was refreshing to be using a product that had been developed for the industry."
- Great Places Housing Group

"The programmes do what we need them to do and enable us to deliver financially sustainable schemes. The support team are fantastic and always available."
- Hastoe
