When considering to work with an interior designer one of the first questions you might ask is “how much do they charge?” In todays blog post we are going to discuss the ways interior designers charge and what the different terms mean.

Fee Structure

Interior designers commonly charge a fixed fee, an hourly rate or a percentage of the total project cost. In a recent study done by the BIID it was found that 60% of senior interior designers charge up to £75 an hour and 40% charge £76-£150 an hour.

For a fixed fee the interior designer will look at the scope to see how much time and resources they need to complete the project. The fee will be broken down into stages: brief, concept, detailed design, technical design, construction, procurement and installation. How many revisions to the design and how much time on site has been allowed for in the fee must be agreed by the client and designer from the onset.

Hourly rates are billed based on the exact time spent on the project. Throughout the course of the project a detailed timesheet will be kept for reference. Hourly rates differ based on location and experience. Typically a larger practice will charge higher rates to cover overheads. Clients can be charged on a stage by stage basis or for a particular stage if the designer isn’t needed for the entire project.

A percentage fee based on the total project cost is normally around 10-15%. It is wise to get an estimate of the project cost from the beginning so you have a clear idea of the design fee. The client will be charged on a stage by stage basis.


Interior designers often offer procurement of FF&E (furniture, fixtures & equipment) as part of their services. It is common for interior designers to put a percentage fee on top of FF&E which is bought for the project. There are various terms for this such as: a mark up, purchasing fee or handling fee, this fee is usually between 10%-20% of the total cost of the FF&E.

Trade Discounts

Interior designers get trade discounts on furniture, flooring, lighting, sanitary-ware, fabric, accessories, appliances, electrical items and more. Trade discounts vary from 10% up to 40% off the retail price, this can save the client a considerable amount.
