Typical HMO Conversion Cost Breakdown

Converting a property to an HMO involves a range of costs. Key categories include:

1. Refurbishment and Build Costs

These are often the largest expense and depend on property size and specification:

• General renovation works

• Kitchens and bathrooms for multiple users

• Flooring, décor, and internal partitioning

• Fire safety upgrades

• Electrical and plumbing upgrades

Typical refurbishment costs for UK HMO conversions range from £15,000 to £50,000+, depending on size and standards required.

2. Planning and Design Costs

• Architectural plans and drawings

• Planning application fees (if required)

• Party wall agreements

Costs vary, but planning and design can range from £2,000 to £10,000+, especially in Article 4 Direction areas or conservation zones.

3. HMO Licensing and Compliance

Landlords must apply for the correct licence(s):

• Mandatory, additional, or selective HMO licence fees

• Safety certificates (Gas, electrical)

• Fire risk assessments

• EPC (Energy Performance Certificate)

Licence fees vary by council but can range from £800 to £2,500+.

4. Professional Fees

• Project management

• Quantity surveying

• Legal fees

• Lettings agent fees

Professional costs vary based on the level of service provided.

5. Contingency Budget

Always include a contingency of 10–15% of total project costs to cover unforeseen issues during renovation.

Factors Affecting HMO Conversion Costs

Several variables influence the final conversion cost:

• Location – London and major cities usually have higher labour and compliance costs.

• Property condition – Older properties may require more extensive works.

• Licensing requirements – Boroughs with selective/additional licensing add compliance costs.

• Planning constraints – Article 4 Directions or conservation areas can increase design and planning expense.

Fraser Bond assists landlords in forecasting realistic conversion budgets tailored to specific UK locations and property types.

Return on Investment (ROI) Considerations

Investors should budget with return in mind:

• Compare potential HMO rent vs current market single‑let rent

• Factor in void periods, operating costs, and management fees

• Assess long‑term capital appreciation

A well‑executed HMO conversion often yields higher rental income, faster cost recovery, and stronger portfolio performance.

Fraser Bond helps investors model ROI and make informed decisions on HMO conversions.
