How much do architects charge in London?

How much an architect in London will charge for architect fees will vary considerably depending on the complexity of the project, the size of the firm, and the reputation they’ve built up.
The Royal Institute of British Architects (RIBA) provides guidance on architect fees based on the type of project and the stages of the work. For a residential project, they suggest that architect fees can range from 7% to 12% of the total construction cost for a full service, which includes all stages of the design process from planning to construction.
It is important to note that these are only guidelines and some architects may charge higher or lower architect fees depending on the way they work. It can also be common for architects to charge a fixed fee or hourly rate rather than a percentage of the construction cost.
The best way to determine architect fees is to contact several architects you like the look of and request a detailed proposal outlining their fees and services. That way you can compare architect fees and get a better understanding of what you get for your money.
