HMO Conversion Costs Average £82,000, New Estimate Finds

A new estimate puts the cost of converting a property into a house in multiple occupation (HMO) at over £82,000. The research puts the average conversion cost at £15,275 per bedroom across England.

The figure is based on an average HMO size of 5.37 bedrooms, which equates to a total estimated conversion cost of more than £82,000. Landlord Today reports the estimate under the headline question of whether converting a house into an HMO is worth it.

What the figures cover

The research provides a per-bedroom average conversion cost of £15,275 across England. Applied to the average HMO size of 5.37 bedrooms, this produces the total estimated conversion cost of over £82,000 cited in the report.

The source does not break the estimate down by region, property type or specification, and it does not set out a timescale for the works involved.

Why this matters for letting agents and inventory clerks

For letting agents, the estimate offers a headline benchmark when landlords ask about the likely outlay of moving into the HMO sector. It also shows that HMO conversions involve a substantial upfront commitment before any rental income is generated.

For inventory clerks, HMO conversions typically bring a different schedule of condition from a single-let house, with more bedrooms and shared facilities to record. The source does not detail compliance requirements, licensing rules or room standards associated with HMO conversions, so those points are not covered in this brief.

The report does not state whether the estimate includes professional fees, licensing costs or furnishing, and it does not offer a view on yields or payback periods. It also does not include any commentary from named individuals.

Agents fielding landlord enquiries on HMO viability should treat the £15,275 per-bedroom figure and the resulting £82,000-plus total as the key data points from this report, and refer to the original article for the full context.
