Complaints performance
We take all complaints that we receive seriously and have put a lot of work into making our process fair and easy to follow.
Annual complaints and service improvement report
We’re dedicated to openness and transparency with our customers. In line with the Housing Ombudsman Service (HOS) Complaint Handling Code, here’s a summary of Stage 1 and Stage 2 complaints we’ve received during 2024/25, including case details that were escalated to the HOS.
Customer voice and learning from complaints
Through our complaints process, customers can hold us to account. Complaints and lessons learned enable us to focus on getting things right first time, understanding customers better and using what they tell us to improve our services.
Complaints learning is one of the mechanisms by which we understand, and act upon, the customer voice. Effective complaint handling is an important mechanism for customers to be able to hold their landlords to account when things go wrong. Under the UK Government’s Transparency, Influence and Accountability Standard landlords must have a clear approach to complaints so that customers can raise their concerns and when they do, landlords listen to what they are being told, have effective processes for handling the complaint and act promptly to put things right.

The role of the Housing Ombudsman Service (HOS)
The Housing Ombudsman Service (HOS) Complaint Handling Code came into effect from 1 April 2024. Besides handling complaints day-to-day, the code also says landlords need to put together a yearly report on complaints and how they’re improving their services. This report should be shared on their websites and sent to the HOS at least once a year. It should include:
- The annual self-assessment against the Code
- An analysis of complaints handling performance
- Any times the HOS found the landlord didn’t follow the Code
- Improvements the landlord has made based on what they’ve learned from complaints
- What the landlord has done in response to any yearly performance reports from the HOS
- Any steps taken after other relevant reports or publications from the HOS about the landlord’s work
- The governing body’s response to the report

Stage 1 complaint outcomes
Repeat complaints were investigated from a number of customers:
- 184 customers – the majority of these customers raised two complaints each
- 14 customers raised 4+ complaints each
Outcome: Four of these customers have been assessed as ‘high support’ to make sure our services are tailored to their needs.
Our TSM (Tenant Satisfaction Measure) for Stage 1 complaints handled on time in 2024/25 was 97.4% which is a significant increase on 76% in 2023/24 and demonstrates our commitment to improve our response times.
We’re pleased to see such a huge improvement, although there has been a 18% increase in the number of cases being extended, which could be explained by the increase in volume. We are actively seeking to reduce extensions in 2025/26.

Failed promises are the biggest theme in Stage 2 complaints in 2024/25 as well as 2023/24, indicating this is the most emotive theme for customers.
How we’re tackling this:
- To address failed promises the Customer Experience team now track all Stage 1 complaint commitments, with 420 commitments monitored through to completion in 2024/25.
- Our planning team now has visibility of complaint-related repairs, helping prevent unnecessary rescheduling and reducing customer dissatisfaction.

Complaint demographics
The profile of customers raising a complaint generally mirrors One Manchester's overall customer base, with the exception of Black / Black British African customers who are underrepresented. This data has been cross referenced with our TSM data which tells us Black / Black African customers are generally more satisfied with One Manchester (79% compared to a 73% average) and significantly more satisfied with complaint handling (57% compared to a 43% average) so a lower volume of complaints does align here. However, we will actively encourage representation from Black / Black African customers when we recruit to our complaints and performance customer group in 2025/26.
There are five neighbourhoods where we received over 60 complaints per neighbourhood. Three of the five were in the Central region which is also the region with the most complaints overall. This is not unexpected as the majority (58%) of our high-rise stock falls within this one region. Analysis shows that our high-rise customers are proportionally more dissatisfied than customers of other property types (14.3% of complaints compared to 11% of stock). We’re addressing this by increasing stock condition surveys to understand property condition and what repairs and maintenance are needed. We’ll explore this further with our customer groups in 2025/26 and also regularly review complaints by neighbourhood to review and address any emerging themes.
Housing Ombudsman Service cases
Customers can escalate to the Housing Ombudsman Service (HOS) if they feel that our complaints process has been exhausted and they remain dissatisfied.

Continuous improvement and learning from complaints
The restructuring of the Customer Experience team and ongoing recruitment throughout 2024/25 — expanding the team from seven to nine members — has made sure we’re resourced to manage complaints in full compliance with the Housing Ombudsman Service's Complaints Handling Code. This also enables us to maintain a strong focus on learning from complaints and enhancing customer engagement.
How we’re striving to improve:
- Complaints learning sessions and customer journey mapping with Repairs, Neighbourhoods, and Assets have taken place regularly throughout the year, with any tactical interventions and outcomes reported to our Leadership Team, Customer and Communities committee, and Board.
- To address failures to resolve complaints at Stage 1, the Customer Experience team has implemented tracking of all “promises” made during a Stage 1 complaint investigation and these actions are reviewed regularly through to completion.
- We introduced complaints transactional surveys in December 2024 to identify what was and wasn’t working well for customers around complaints handling. Responses indicated that a high proportion of customers found the triage step which was introduced from April 2024 (to fully understand the complaint, the desired outcome, and any reasonable adjustments) beneficial.
- Following our “Big Listen” customer consultation in 2023/24, and the high volume of repairs-related complaints, we implemented a repairs intervention in 2024/25. The intervention team, working closely with our Customer Scrutiny Panel, have completed the intervention “check” phase. We’re carrying out identified improvements and throughout 2025/26 new ways of working will be rolled out to improve the customer experience and address recurring themes of dissatisfaction.
We’ve also implemented multiple fixes to address customer dissatisfaction outside of the intervention, including:
- To address the high volume of joinery related complaints we have recruited to the team to increase appointment availability and reduce work backlog. This led to a reduction of joinery related complaints in the latter part of the year.
- In recognition of a large volume of complaints relating to fencing we utilised a sub-contractor to clear a back-log of jobs and in turn improve customer satisfaction. We also agreed a budget to increase in-house fencing team resource in 2025/26 to reduce a reliance on subcontractors giving us greater control of timescale and communication.
- Completed stock condition surveys to 75% of high-rise properties, meaning greater pro-activity around repair and replacements.
- To address complaints about ongoing repairs, and escalations due to work remaining incomplete we introduced a new approach to follow on work. By the end of the year this resulted in a 60% reduction in outstanding work, and where a first time fix was not possible outstanding work was booked in within 24 hours resulting in better communication and clarity for customers.
- Reduction in repairs backlog from January to April 2025.
- To reduce customer dissatisfaction around missed appointments we implemented a new “no access” procedure in repairs which reduced instances of no access by 50% by the end of March 2025.
- Monthly reviews of complaints by ethnicity revealed high arrears in one ethnic minority group, enabling us to tailor support messaging. We’ve also regularly reviewed compensation payments by ethnicity to ensure there is no conscious or unconscious bias in our compensation offers.
- In 2025/26 we will be co-creating welcome packs and service standards with customers to better manage expectation and clarity around services, and gas safety letters with customers as a result of increased complaint volumes in Q3.
- We’ll implement improvements recommended by our customer scrutiny panel once their complaints handling scrutiny in Q1 2025/26 is complete.
- Our current complaints position is shared with all complaint handlers and the Leadership Team on a weekly basis. Complaints performance has also been shared quarterly with Customers and Communities Committee and Board, and regular meetings have taken place between the Head of Customer Experience and our Member Responsible for Complaints (MRC). Actions arising from MRC meetings are documented and shared with Customers and Communities Committee.
