Which housing association has the most complaints?

London & Quadrant Housing Trust has the most upheld Housing Ombudsman findings among housing associations in this ranking, with 914 adverse findings across 989 published decisions. By severe maladministration findings, London & Quadrant Housing Trust leads with 220.

That answer needs an important caveat. "Most complained about housing association" is a phrase people use in search, but the table below does not count every complaint made to a landlord. It counts published Housing Ombudsman determinations that Landlord Record has structured and ranked. A landlord can receive complaints that never reach a published determination, and a landlord can resolve complaints before the Ombudsman makes a formal finding.

The distinction matters because an Ombudsman determination is a late-stage record. Before a case reaches that point, a resident normally complains to the landlord, the landlord has a chance to respond through its complaints process, and some disputes are settled or resolved. The Ombudsman record therefore shows complaints that reached a formal published outcome, not the full volume of calls, repair reports, service requests or internal complaints a housing association receives.

That makes the data powerful but narrow. It is useful when you want to know which landlords appear most often in upheld Ombudsman decisions, which landlords have the most serious findings, and where compensation has been ordered. It is less useful if you want a complete customer-service score for every housing association, because the source data is the Ombudsman's published decision archive rather than each landlord's internal complaints system.

The ranking sits inside our current index of 16,224 published decisions across 603 landlords, including 2,499 decisions marked as severe maladministration. Source: Landlord Record analysis of Housing Ombudsman decisions (OGL v3.0).

Top housing associations by upheld findings

The table ranks housing associations by adverse findings from the live worst-landlords-overall ranking, then joins each landlord to its Landlord Record profile data. "Adverse findings" means the Ombudsman found service failure, maladministration, partial maladministration or severe maladministration in published determinations.

Read across the row before drawing a conclusion. A landlord with many adverse findings may also have a very large published caseload. Another landlord may have fewer decisions but a higher share of those decisions found against it. A third may stand out because the severe column is high, even if its overall count is lower. Those are different risk signals, and they should not be collapsed into a simple "worst" label without context.

Why raw complaint counts can be unfair

Raw counts favour large landlords. A provider with more homes, more repairs, more estates and more tenancies has more opportunities for disputes to reach the Ombudsman. That does not mean raw volume is useless. It shows where the published Ombudsman caseload is concentrated. But it should not be the only way you judge a landlord.

The fairer reading is to use several columns together. Decisions show the size of the published Ombudsman record for that landlord. Maladministration rate shows the share of decisions where the Ombudsman found against the landlord. Severe findings identify the most serious outcomes. Compensation shows the total ordered in the indexed decisions. Findings per homes gives a size-adjusted signal where the homes figure is available.

The severe column is especially important for a journalistic reading of the data. Severe maladministration is not just a higher count in the same table; it is the Ombudsman's most serious finding category. A landlord with fewer total adverse findings but a prominent severe record may deserve closer scrutiny than a landlord whose adverse findings are mostly lower-level service failures. That is why this guide names both the overall adverse-finding leader and the severe-maladministration leader where the query data is available.

Compensation is another useful but limited signal. A high total compensation figure can indicate repeated findings, serious impact, large awards, or a mixture of those things. It does not tell you, on its own, whether the current service is improving or worsening. To understand the pattern, click through to the landlord profile and read the underlying decisions. The table is the starting point for scrutiny, not the whole story.

Where the per-homes column says "Not available", Landlord Record does not have a usable homes denominator from the existing query data for that landlord. Rather than estimate it, we leave the cell blank. That is deliberate: this page is built for citation, and the numbers should be traceable to the data layer at build time.

What the ranking does and does not prove

This page can answer a precise question: which housing association has the most upheld findings in Landlord Record's structured Housing Ombudsman dataset? It can also show which housing association has the most severe findings, and how each provider compares on the columns exposed by the existing query functions. It cannot prove that a landlord is the worst in every sense, or that another landlord has no serious service problems.

The reason is scope. Published decisions are not a random sample of all residents' experiences. Some residents do not complain. Some complaints are resolved locally. Some complaints are outside the Ombudsman's jurisdiction. Some landlords may have better internal resolution processes, which means fewer disputes reach a published determination. Those realities do not weaken the Ombudsman data; they explain what it should and should not be used for.

The safest reading is comparative and evidence-led. Use the raw count to see where upheld determinations are concentrated. Use the maladministration rate to understand the share of published decisions found against the landlord. Use severe findings to identify the most serious determinations. Use compensation as a financial signal. Then open the landlord's record and read the decision summaries before relying on the ranking for a complaint, article or campaign.

How this ranking is calculated

The main ranking starts with getRanking('worst-landlords-overall'), which orders landlords by adverse findings. The page then filters those rows to landlords whose profile type is housing association in listLandlords(). It joins back to listLandlords() for decisions, maladministration rate, severe findings, compensation and findings per homes. The severe leader comes from getRanking('severe-maladministration') using the same housing-association filter.

The underlying source material is the Housing Ombudsman Service's published decisions. Landlord Record is an independent analysis layer: we organise determinations, extract standard fields and present searchable rankings. We do not change the Ombudsman's findings, and the figures should be read as analysis of published determinations rather than a complete regulator scorecard.

The page deliberately does not add any manual corrections, local spreadsheets or estimated fields. If an item is not returned by the existing query functions, it is left out. That is also why the table uses "Not available" rather than filling missing size-adjusted values from outside sources. The trade-off is that the page may be less complete than a bespoke investigation, but it remains reproducible from the site's own build-time data.

Who regulates housing associations?

Two official bodies are commonly confused. The Housing Ombudsman handles individual complaints about member landlords and publishes determinations when cases reach a formal outcome. The Regulator of Social Housing regulates registered providers of social housing in England. A resident complaint about repairs, complaint handling or landlord service may belong in the landlord complaint process and then the Ombudsman route; wider regulatory questions sit with the regulator.

For residents, the practical first step is usually not to start with a league table. It is to report the problem clearly, keep evidence, use the landlord's complaint process and escalate if the response is not adequate. The ranking helps you understand a landlord's published Ombudsman record. It does not replace the steps needed to get your own complaint investigated.
