What can loft conversion companies help with?

Loft conversion companies, mostly comprised of a number of skilled builders, offer comprehensive services to maximise your home’s potential, including:

  • Design and Planning: Crafting detailed plans that comply with local building regulations and improve space efficiency.
  • Structural Alterations: Strengthening floors, adjusting roof structures, and modifying the loft space to accommodate new room layouts.
  • Insulation and Ventilation: Ensuring that the new space is comfortable, energy-efficient, and meets all thermal and acoustic insulation standards.
  • Windows and Natural Light: Installing skylights, dormer windows, or Velux windows to bring natural light into the loft area.
  • Stairs and Access: Designing and installing safe and aesthetically pleasing access points to the new loft space.
  • Utilities and Services: Extending electrical wiring, plumbing, and heating to the loft, including the installation of new heating systems or air conditioning as required.

What should I consider when hiring a loft converter?

  1. Are a skilled company with a strong history of high standard projects  
  2. Have all the necessary licences and insurance needed to protect you and their workers 
  3. Have a good range of positive reviews from previous customers vouching for their reliability  
  4. Are offering the tree surgeon services you need, and are available to carry out the work in the timeframe you need it to be completed by 
  5. Are quoting a price and payment option that you are happy with, having compared the quote with other tree surgeon companies

How much do loft conversions cost?

The cost of a loft conversion varies widely based on several factors, including the type of conversion, the size of the loft, the materials used, and your geographic location. Understanding these factors can help you budget appropriately for your loft transformation project.

Types of Loft Conversions and Cost Implications

  1. Velux Conversions: Often the most cost-effective option, Velux conversions involve installing roof windows without altering the existing roof structure. Prices generally range from £22,500 to £30,000.
  2. Dormer Conversions: These are among the most popular types of conversions. They involve extending the existing roof to create more headroom and usable space. Costs for dormer conversions typically range between £40,000 and £60,000.
  3. Hip-to-Gable Conversions: This type of conversion changes the sloping side of a roof (hip) to a flat side (gable), increasing the usable interior space. They are suitable for semi-detached and detached homes, with costs ranging from £50,000 to £70,000.
  4. Mansard Conversions: Involve replacing one or both roof slopes with steeper sides and a flat roof on top, dramatically increasing space. These are more complex and can cost between £50,000 and £80,000.
  5. Modular Loft Conversions: These are built off-site and then installed, minimising disruption and construction time. Costs vary from £30,000 to £60,000 depending on the design and materials.
  6. Bungalow Conversions: Since bungalows have a single-story layout, converting the loft can almost double the living space. These conversions generally cost between £62,500 and £87,500 due to the larger area covered.

Additional Costs to Consider

  • Design and Architecture Fees: Depending on the complexity of the project, architectural services can add 10-15% more to the overall cost.
  • Planning Permissions: If your conversion requires planning permission, this will incur additional costs for the application process.
  • Structural Alterations: Major structural changes, like reinforcing floors and altering roofs, can increase costs significantly.
  • Building Regulations: Meeting building regulations is essential and will require spending on inspections and compliance measures.
  • Interior Finishing Costs: These include costs for fixtures, fittings, electricals, and decoration, which can vary widely based on your choices.
  • External Access: If scaffolding or other external access equipment is needed, this will also add to the project cost.

Budgeting for Your Loft Conversion

To ensure you budget effectively, it’s advisable to obtain multiple detailed quotes from different contractors. Each quote should break down all the costs involved, including a contingency budget of around 10-20% to cover unexpected expenses during the construction process. This detailed planning helps in avoiding surprises and ensuring your loft conversion stays within financial bounds.

Other loft conversion FAQs

What is the 10 year rule with loft conversions?

This rule refers to obtaining a certificate of lawfulness for an existing use of a converted loft if it has been in continuous use for at least 10 years without planning permission.

Is a loft conversion cheaper than an extension?

Generally, loft conversions can be cheaper and less disruptive than building an extension, as they often require fewer structural alterations.

Are loft conversions very cold in the winter?

With proper insulation and heating solutions, a loft conversion should be as warm and cosy as any other part of your home.

Carl and the team undertook a full landscape, fencing and decking project. It wasn't a small task, with hidden tree stumps, heavily overgrown garden and uneven levels. The team were brilliant and had the whole garden fully landscaped, including a new fence, roll on lawn, deck and a few other additional tasks completed within a week. Team turned up on time every day and worked solidly to get the job finished within the quoted timeframe. Would strongly recommend Root2Roof for the works they completed.
