London interior designers: 10 checks

There is no single interior design studio that is right for every London home. The right fit depends on the property, the aesthetic and the budget. It also depends on how much senior involvement you want. Some clients need design only. Others need one team responsible for delivery as well.

Published rankings of interior designers are advertisements. They do not know your building, your brief or your budget. What follows is the set of checks that actually separates one studio from another.

Why there is no right studio for every home

A studio with a strong signature look will give you that look. That is the point of appointing them. It is also the risk. Your house or your taste may pull in a different direction. A studio with a broader range gives you more latitude. It also gives you less certainty about the outcome. Neither is better. Decide which you want before you meet anybody.

Ten checks before you appoint a designer

1. Completed homes, not mood boards

Ask to see finished rooms that were actually built, photographed after handover. Details and visualisations tell you about taste. Completed work tells you about delivery. Review the NU Projects portfolio for what that evidence looks like.

2. A design identity that can still listen

Look for a recognisable approach. It should clearly have been adapted to different buildings and different clients. A portfolio where every project looks identical is a template.

3. The named team

Ask who leads the design and who you will deal with day to day. On a lot of studios those are not the same person. That is fine as long as you know it before you sign.

4. The written scope

Space planning, interior architecture and lighting design are separate pieces of work. So are joinery drawings and furniture, fixtures and equipment. Confirm which are included and which are extra.

5. Coordination with the building

Ask how the designer will work with the architecture, structure and building services. An interior scheme can ignore ceiling voids, riser positions and grille locations. If it does, it gets changed on site.

6. The fee and the purchasing structure

Compare the written scope, the design stages, procurement responsibility and purchasing terms. Also compare expenses, the number of revisions included, site attendance and exclusions. The headline fee on its own tells you very little.

7. Who buys the furniture

Procurement is where a lot of the money and most of the risk sits. Ask who places the orders and who holds the deposits. Ask who chases the lead times, and who is responsible when something arrives damaged.

8. Site involvement

Ask how often the designer will be on site. Ask who checks setting out against the drawings. Ask who signs off samples and mock-ups before installation.

9. When you should appoint

Early, before layouts and building services are fixed. An interior designer brought in after the first fix is choosing finishes. They are not shaping the house.

10. What happens at the end

Styling, installation, snagging and the handover of specifications and maintenance information. Ask what is included after the last delivery arrives.

Design studio or integrated design and build?

A traditional studio designs and procures interiors. It works alongside separate architects, consultants and contractors. An integrated route places more of those responsibilities in one team. Neither removes the need for clear appointments. But the interfaces, the cost reporting and the accountability are different.

Read architect or design and build, which route is right for a wider comparison.

What a complete service can cover

Depending on the appointment, that can mean briefing, layouts, concept design and lighting. It can also cover bathrooms, kitchens, materials, bespoke joinery, furniture, procurement, styling and installation. On a major renovation the designer must also coordinate with structure and fire safety. The same applies to acoustics, heating, cooling, ventilation, electrical systems and the construction sequence.

NU combines interior design with architecture, quantity surveying and building services. It adds construction, bespoke joinery and aftercare. That suits clients who want each design decision tested as it is made. The test is against cost and buildability. See the Mayfair apartment interior for a completed example.

Frequently asked questions

Is there a reliable ranking of London interior designers?

No. No independent body audits the work, so any published order is marketing. Compare evidence and written scope against your own brief.

How should I compare interior design fees?

Compare the written scope, design stages, procurement responsibility and purchasing terms. Compare expenses, revisions, site involvement and exclusions too, not the headline fee.

When should I appoint an interior designer?

Before the layouts and the building services are fixed. That way the interior strategy can still influence architecture, lighting, services, cost and procurement.
