Before you appoint JW Block Management

1
Verify TPO registration
Check the company is currently listed on the TPO register at tpos.co.uk ↗ — not just that they claim to be registered.
2
Confirm TPI membership if claimed
If they advertise TPI membership, verify it directly at tpi.org.uk ↗. Membership lapses are not always prominently disclosed.
3
Ask for the last two years of service charge accounts
Request certified service charge accounts for a comparable block they currently manage. Look for transparency on reserve fund contributions and major works expenditure.
4
Review the management agreement carefully
Before signing, check the notice period to end the contract, any early termination fees, and the full fee schedule — including charges for routine tasks that may not be covered by the headline management fee.
5
Read reviews on both Google and Trustpilot
Neither source is definitive on its own. A strong score on one platform alongside a poor score on another is worth investigating — check recency and whether responses to negative reviews are constructive.
