Before you appoint Best Gapp

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.

Confirm TPI membership if claimed

If they advertise TPI membership, verify it directly at tpi.org.uk ↗. Membership lapses are not always prominently disclosed.

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.

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.

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.
