London HMO: Management Company vs Self-Manage — Compliance Considerations

The Core Decision: Management Company or Self-Management

For London HMO landlords, the decision whether to engage a property management company or self-manage is not purely financial. It has direct implications for compliance — specifically, who takes responsibility for ensuring that the CP12, EICR, Fire Risk Assessment, PAT testing, Legionella assessment, and all other required certificates are obtained, current, and documented. Understanding the compliance dimension of this decision is as important as understanding the management fee structure.

Advantages of Using a Management Company

A good HMO management company in London brings systems and processes that an individual landlord managing a small portfolio may find difficult to replicate. Compliance scheduling — tracking renewal dates across multiple certificates, booking engineers in advance of expiry dates, and chasing documentation — is a core service of full management. The management company maintains the compliance file, ensures each certificate is issued to tenants within the required timescales, and typically handles the assembly of documentation for HMO licence renewal applications.

Beyond compliance, a management company handles tenant sourcing and referencing, tenancy agreements, deposit protection, rent collection, routine inspections, and maintenance coordination. For a landlord who does not live in London or who has a demanding professional life alongside their property portfolio, delegating these functions to a professional manager has obvious appeal.

Disadvantages of Using a Management Company

Management fees for a full management service on an HMO in London typically fall between 10 and 15 per cent of gross rent. On a six-bedroom HMO generating £4,000 per month, this is £400 to £600 per month in management fees — a significant cost over the course of a year. Fee levels vary considerably between operators, and the quality of service does not always correlate with the fee level. Some management companies in London treat compliance as an administrative tick-box exercise rather than a genuine risk management function: certificates are obtained at the minimum standard but without the oversight and follow-through that an engaged landlord would apply.

Loss of direct control is the other significant disadvantage. A management company will make decisions about tenant selection, maintenance priorities, and even compliance works in ways that may not align with how the landlord would manage the property themselves. Reviewing management company compliance records at each licence renewal and conducting periodic spot-checks of the compliance file is sensible even for landlords who have delegated management entirely.

Self-Management: Cost Saving and Full Control

Self-managing an HMO in London is entirely feasible for landlords who invest the time to understand their obligations, build a reliable network of contractors, and maintain organised compliance records. The cost saving versus full management is substantial. The direct relationship with tenants allows faster response to issues and potentially stronger tenancy retention. The landlord who self-manages has direct visibility of the property condition, the tenant relationships, and the compliance status.

Self-Management Compliance Obligations

It is essential to understand that self-managing landlords retain full legal responsibility for every compliance obligation regardless of what any management arrangement specifies. The law does not recognise a management company as the duty holder — it is always the landlord. Self-managing landlords must ensure: the CP12 is renewed annually by a Gas Safe registered engineer; the EICR is renewed within the interval specified by the HMO licence; the Fire Risk Assessment is reviewed annually; PAT testing is carried out annually on all landlord-supplied appliances; the Legionella risk assessment is reviewed annually; all smoke and CO alarms are installed, interlinked where required, and tested at the start of each tenancy; fire doors are maintained in compliant condition; and the HMO licence application for renewal is submitted well before expiry with all supporting documentation current.

What Must Be Done at Each New Letting

At the start of each new tenancy, whether self-managing or using an agent, the following compliance steps are required: confirm that all current certificates are valid and will not expire during the early months of the tenancy; provide the tenant with the current CP12, the current EICR, the gas safety record for any gas appliances in their room, the EPC, the How to Rent guide, and the government prescribed information for their deposit; test all smoke alarms and CO alarms in the presence of the tenant and document the test; conduct right-to-rent checks for all adult occupants; protect the deposit with a government-approved scheme and serve the prescribed information within 30 days; and confirm that the HMO licence permits the intended number and configuration of occupants.

What a Good Management Agreement Should Include Regarding Compliance

If you engage a management company, review the management agreement carefully for its compliance provisions. A robust management agreement should specify: which compliance certificates the management company is responsible for obtaining and at what cost; the process for notifying the landlord when certificates are due for renewal; the process for providing certificates to tenants; who is responsible for assembling the HMO licence renewal documentation; what happens if a certificate cannot be obtained in time (for example if an EICR reveals defects requiring remediation); and what reporting the management company provides to the landlord on compliance status. Vague or absent compliance provisions in a management agreement are a red flag.

The Hybrid Approach

Many London HMO landlords adopt a hybrid approach: self-managing the tenancy relationship — marketing, referencing, rent collection, communication — while outsourcing the compliance certificates to specialist contractors. This retains the cost saving of self-management while ensuring that the CP12, EICR, Fire Risk Assessment, PAT testing, and Legionella assessments are handled by specialists who understand the HMO compliance context and not simply the minimum legal standard.

Prestige Engineers works with London HMO landlords who self-manage their properties to provide a reliable, scheduled compliance service. We maintain records of your certificate renewal dates, contact you in advance of each renewal, carry out the required inspection or assessment, and provide the documentation in the format required for both your compliance file and your HMO licence renewal application. For a self-managing landlord, a compliance partner who handles the technical certificates is often a more effective and cost-efficient arrangement than either full management or attempting to coordinate all trades independently.
