Budgeting for typical Loft Conversion Cost

The average cost of a loft conversion will still, however, vary depending on a number of different planning and building considerations, including:

  • Whether or not the roof structure is suited to a loft conversion.
  • Whether or not the roof height meets the minimum 2.2m as quoted by most loft conversion companies.
  • The kind of insulation you currently have in the loft and whether or not it needs upgrading. 70mm thick slab foam is usually preferred to simple covers between the roof joists and outer layer of tiles and battens.
  • Choosing between a staircase and a ladder for ease of access.
  • How many windows, skylights and/or dormers you want installed as part of the loft conversion.
  • The type of lighting you want installed, and whether or not you will need to hire an electrician to re-wire the top half of the property.
  • Whether you need to remove an existing water tank from the loft and re-fit pipe work and perhaps even upgrade your heating system as part of the project.
  • If you want the loft conversion to include an en-suite bathroom.

Hiring a Loft Conversion company

Keeping the cost of a loft conversion down means making sure the project goes ahead on time and within budget; and that means hiring the right team for your particular attic refit. You should get in contact with as many different contractors as possible in your local area before you hire any kind of company – you could even get them to visit the property and carry out a preliminary inspection of the loft area to help give you a rough idea of how much the project is going to cost from start to finish. Either way, you want to find a dedicated team of professionals who know what they are doing and who you can communicate with easily and effectively. This will come in handy later down the line – especially if things aren’t going according to plan and you need to start over with a new team altogether!
