10 Things To Consider With A Flat Conversion

A flat conversion occurs when a property is converted from one unit into multiple units or vice versa. There are a variety of different things to consider concerning flat conversions; here are our top ten considerations:


  1. Property suitability – Not all properties are suitable for a flat conversion. Ideally, you need a large semi-detached or detached home, a sizeable non-residential property compliant with Local Plans, bedsits or HMOs or shops with vacant space above.

  2. Fire Regulations – When converting a property into contained flats, each flat must have accessible escape accesses for emergencies.

  3. Sound Insulation – Each floor should have soundproofing to the required standard; this ensures occupants can enjoy quiet home lives.

  4. Room sizes – All rooms have a minimum floor space that must be adhered to and a minimum window area. You must pay attention to the location of rooms like bedrooms and living rooms as they cannot be internal.

  5. Market demand – Research your local area to see if flats are in demand; this will help ensure a sound Return of Investment.

  6. Planning permission – You will need to seek planning permission to convert a house into multiple self-contained flats.

  7. Cost – To convert a house into flats, it will cost approximately £25,000, but this depends on the needed work, materials, and contractors.

  8. Time – Converting houses to flats is not a quick job to complete; it would take about six months to complete as a rough estimate.

  9. Financing – You cannot secure a standard mortgage to convert a property into flats, so you will either need cash or secure some specialist funding.

  10. Selling or Renting – Having an end game is essential; you need to know what you will do with the conversations once completed. For example, renting could earn you up to 20% ROI yearly, whilst selling would give you access to an instant amount of money.


Converting a property into multiple self-contained flats is becoming increasingly popular. Homeowners are seeing profits that are achievable by converting due to the demand for flats.
