Interior designer playbook.
A London interior designer working residential refurbs, prime-property renovations and boutique commercial fit-outs. The win is moving from hourly design fees to fixed-fee phased packages with FF&E procurement margin and project-management uplift.
Overview
A London interior designer running solo or with a junior typically delivers 4–9 full residential projects per year, each £80k–£600k spend including £24k–£180k design + PM fees. The single biggest economic lever is procurement margin — trade discounts of 20–45% off RRP on FF&E (furniture, fixtures + equipment) let the designer mark the supply chain up to client at 15–35% and still beat retail, adding £18k–£120k per project with no extra design hours. The second lever is RIBA-stage discipline: clients who refuse stages 0–1 (briefing + concept sign-off) drive 80% of scope-creep + 70% of unpaid revisions. This playbook covers operationalising a London interior design studio — BIID/SBID registration, trade-account setup, contracts, FF&E procurement and the project-management pipeline.

№ 02 / Where to set up
Location is half the business.
Prime / super-prime postcode density
SW1/SW3/SW7/W8/W1/NW8 + Holland Park
Project budgets correlate directly with postcode-median sale price; £600k+ refurbs cluster here.
Supplier showroom proximity
Within 30 min of Design Centre Chelsea Harbour + Pimlico Road
Trade-day visits with clients close projects 2x faster than catalogue-only flows.
Contractor network
8+ vetted main contractors covering Zones 1–4
FF&E margin only protects if the build runs on time; weak contractor pool kills the model.
Studio presence
Bookable sample room or own showroom corner
Clients sign 60% faster when they can touch fabrics + finishes in person.
