FAQ: Your questions about loft conversions answered

What should I expect from a loft conversion company?

A specialist loft conversion company will handle the process from design through to completion. This includes providing detailed plans, dealing with planning permission or permitted development checks, ensuring structural safety (including joist strengthening and fire safety compliance), and managing all trades involved. You should expect transparent pricing, a clear schedule, and full adherence to Building Regulations.

Do loft conversion companies need insurance?

Yes. They should hold public liability insurance to cover property damage or injury, and employer’s liability insurance if they have a team. Companies offering design or structural services should also have professional indemnity insurance.

What questions should I ask before hiring a loft conversion company?

Ask whether they’ve completed similar conversions in properties like yours especially if it’s an older or listed building. Check who will manage planning applications and building control, what their typical timelines are, and whether they offer a fixed or itemised quote. It’s also useful to confirm how they handle unforeseen costs, subcontractors, and any aftercare once the project is complete.

Do I need planning permission for a loft conversion?

Not always. Many loft conversions fall under permitted development rights, especially dormer and rooflight-style conversions, provided they meet specific volume and set-back rules. However, if your home is in a conservation area, or you’re altering the roofline significantly, planning permission is usually required. A good company will guide you through the permissions process from start to finish.

How long does a loft conversion usually take?

The timeline of your loft conversion will vary lots depending on the size and type of conversion. A straightforward Velux or rooflight loft conversion can take around 4 - 6 weeks, while a dormer or mansard conversion may take 8 - 10 weeks or more. A loft conversion company should provide a clear schedule tailored to your design and property.
