What changes the price
- Finish qualityPlain, functional finishes suit budget or student lets; a higher specification (better flooring, fitted furniture, upgraded bathrooms) suits professional tenants and commands higher rent. Your target tenant should drive this, not just the budget.
- Structural workRemoving chimney breasts, replacing floors throughout and the overall size of the property all add cost. Stripping and rebuilding a large property is a different job to a smaller, contained conversion.
- En-suite vs sharedAn en-suite in every room commands higher rent but adds plumbing, waterproofing and fit-out cost to each room, compared with shared facilities.
- Kitchen provisionA single shared kitchen is the simpler, lower-cost option. Kitchenettes in individual rooms suit higher-spec lettings but significantly increase plumbing, electrical and ventilation work.
- Fire safetyInterlinked smoke alarms, heat alarms in kitchens and fire doors with self-closers on every bedroom and communal room are required for a licensed HMO, whatever the room count.
- Additional space neededIf the existing layout can't reach compliant room sizes through reconfiguration alone, a dormer or extension adds the floor area needed, as new-build work on top of the internal conversion.
- Planning routeSmall HMO conversions (3 to 6 occupants) are often Permitted Development, but that right is removed in Article 4 areas, including some parts of Greater Manchester, where full planning is needed instead.
Licensing fees are separate from build cost. Mandatory, additional and selective licensing fees are set by each council and aren't included in the ranges above. We confirm the exact fee for your property's local authority as part of the feasibility check; see HMO conversions for the full licensing and compliance picture.
These are indicative estimates for budgeting, not a fixed quote. Final pricing depends on the drawings and full scope of works agreed for your project, and can vary from these ranges once a site visit and detailed design are complete.

Set the number of lettable rooms, and any extra floor area you'd need to add through a dormer or extension. It uses the ranges above, so it's a starting point, not a quote.
HMO conversion costs, explained
Is this the price I'll actually pay?
No. These are indicative ranges to help you budget before speaking to us. Your actual price depends on room count, en-suite specification and the property's existing layout, and we always provide a detailed, itemised written quote after a site visit.
Does the price include HMO licensing fees?
No. Licensing fees are set by each council and aren't included in the build cost. We confirm the exact fee for your property as part of the feasibility check, so it's in your overall budget separately from the construction cost.
Does the price include fire safety compliance?
Yes. Interlinked smoke alarms, heat alarms in kitchens, fire doors with self-closers and the other fire safety measures a licensed HMO needs are included in the per-room figures, not charged as an add-on.
Does an HMO conversion need planning permission?
Often not for a small HMO (3 to 6 occupants), which is usually Permitted Development unless the property is in an Article 4 area. Larger HMOs generally need full planning regardless. We check this for your property at the feasibility stage.
How can I keep costs down without cutting corners on compliance?
Choosing shared facilities over en-suites in every room reduces plumbing and fit-out cost, and getting the room layout right against licensing conditions in the first design avoids expensive rework. Fire safety and licensing aren't areas to cut: the risk of fines and Rent Repayment Orders far outweighs the saving.
