If you have started searching for an interior designer in London, you have probably noticed that pricing is all over the place. One studio quotes a flat fee, another charges by the hour, a third wants a percentage of your total spend — and none of it seems to line up. So let’s clear it up properly.
In London, interior designer fees in 2026 typically range from £75–£250 per hour, £1,500–£6,000 per room, or 10–20% of the total project cost for full-service design. Which model suits you depends on the size, complexity and stage of your project.
Hourly rate: Best for small, focused projects or consultations. Typically £75–£250 per hour depending on the designer’s experience and reputation.
Per room / fixed fee: A set price for a defined scope, usually £1,500–£6,000 per room. Good for clients who want cost certainty upfront.
Percentage of project cost: Common for full renovations, typically 10–20% of total spend. This aligns the designer’s incentives with the quality of the finished project.
Full-project / retainer: A comprehensive fee covering design, sourcing, and project management from start to finish — usually the most transparent option for larger jobs.
Scope, scale, and specification are the three biggest factors. A full renovation with structural changes costs more than a styling refresh. Bespoke joinery, imported materials, and multiple revision rounds all add to the fee. Timeline pressure and site access difficulty can also push costs higher.
A fair quote is itemised — you should be able to see what you’re paying for design concept, sourcing, project management, and site visits separately. Be wary of quotes with no breakdown, or fees that seem far below market rate, as this often signals hidden costs later in the project.
At Nour Nagy Designs, we believe in transparent, itemised pricing tailored to the scale of your project — whether that’s a single room refresh or a full architectural fit-out across London, Egypt, or Dubai.
