How long does a loft conversion take?

Typically, a loft conversion can take between **6 and 12 weeks**, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Streatham Hill before agreeing to start the work.

Do I need planning permission for a loft conversion in Streatham Hill?

Many loft conversions fall under **permitted development**, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Streatham Hill loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

**Yes, you’ll need to update your home insurance to cover the conversion**. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

**Many loft conversions allow you to remain in your home**, though noise and dust are inevitable. Some Streatham Hill loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.

Restoration & Refurbishment- 4 Jan 2026
At the outset, Harry and his partner are good people. However, the job was not completed to a professional standard. Grout has started coming off from between the tiles leaving gaps that water can pass through, the door hinge was not properly fitted leaving a door that will not close, the radiator pipe clips were not fitted, tile trims are not flush with rest of the wall, shelves were fitted on top of old broken wood. And the worst part is that Harry did not turn up even after confirming a date to come back and fix the missing parts. I paid him extra for all the additional jobs, even though certain items from the contract were not done ( for e.g. replacing the bathtub panel ). They have multiple jobs ongoing at the same time and struggles to stick to schedule. If you get them I would advise not paying everything upfront and making sure contract is signed only after it is made sure that they would stick to schedule. I struggled to get them to commit to a date and stick to it.
