Landlord Record

Rankings · Updated 2026

The worst housing associations in the UK

Ranked from 18,064 published Housing Ombudsman determinations — by upheld findings of maladministration, severe findings, and compensation ordered. Built only on the Ombudsman’s own record.

How to read this. The first table ranks by the number of upheld findings — the biggest landlords appear high simply because they own the most homes. The second ranks by maladministration rate, a fairer measure. Look at both. Journalists and researchers can also download the league table as CSV.

Questions, answered

Frequently asked questions

Which housing association has the most upheld complaints in the UK?

By volume of upheld (maladministration) findings in published Housing Ombudsman determinations, London & Quadrant Housing Trust has the most — 1,010 adverse findings across 1,099 decisions, including 217 of severe maladministration. Larger landlords naturally accumulate more findings, so we also rank by maladministration rate below.

How is the "worst housing associations" ranking calculated?

It is built entirely from the Housing Ombudsman's published determinations (18,064 decisions). The main table ranks by the number of upheld findings of maladministration; a second table ranks by maladministration rate for landlords with at least 20 decisions, which is fairer to smaller providers. We never go beyond what the Ombudsman decided, and every landlord links to its full record.

Does a high number of findings mean a housing association is the worst?

Not on its own. The biggest landlords manage hundreds of thousands of homes, so they receive — and have upheld — more complaints in absolute terms. Maladministration rate (the share of a landlord’s decisions found against it) and severe maladministration findings give a fuller picture. Use both tables together.

Where does this data come from?

Directly from the Housing Ombudsman Service’s published determinations, released under the Open Government Licence v3.0. Figures update as new decisions are published. Each landlord page links back to the original determinations.
