Update, 24 March 2026: As the Bank of England holds rates, the housing market stabilises and Labour’s tax policies continue to rattle high-net-worth confidence, FCI London surveyed 100 practising London interior designers to find out what is really happening inside the capital’s homes and what it means for the renovation market in 2026.
The Bank of England voted to hold its base rate at 3.75% on 19 March 2026. On paper, that should be good news for London homeowners: mortgage costs are lower than they were twelve months ago, house prices are predicted to rise modestly, and the nightmare volatility of 2022 to 2024 has receded. But inside London’s renovation industry, the mood is considerably more complicated.
FCI London, one of the capital’s leading luxury furniture and interior design retailers surveyed 100 professional interior designers working in London at the start of 2026. The results paint a nuanced, sometimes contradictory picture: budgets are shifting, client confidence is fractured along wealth lines, and the hidden costs of London renovation are proving more savage than anyone anticipated. At the same time, clear design trends are crystallising and a quiet revolt against the open-plan, Instagram-ready home is well underway.
The single most telling finding from the FCI London survey is that London’s renovation market is no longer one market. It is at least three.
The largest single group around 31% of designers surveyed - report that their clients’ average budgets have stayed relatively stable compared to 2024/25. But beneath that headline, the divergence is stark. A significant share of designers report budgets decreasing by more than 10%, driven primarily by middle-market clients spooked by Labour’s tax announcements, VAT on school fees and wider wealth anxiety. Meanwhile, a substantial cohort report budgets increasing by 10 to 20% or even more than 20% - concentrated at the ultra-high-net-worth end of the market, where price is essentially not the driver.
This bifurcation matters for the wider housing market. London house prices are forecast to grow by around 2% in 2026 - modest, but positive. The top end of the prime market, however, is caught in a different gravity field. Labour’s proposed mansion tax (due 2028) and the increase in buy-to-let taxation are already suppressing discretionary investment. Designers working with UHNW clients confirm the hesitation: not a withdrawal from renovation, but a pause while the regulatory landscape settles.
“Less money in pockets, wealth taxes, VAT on school fees and anxiety in the housing market.”
When asked which single geopolitical factor is causing the most disruption, the survey reveals a clear front-runner: domestic UK political uncertainty, driven by Labour’s housing and planning policy announcements, is cited by the largest share of designers as their primary pressure point. Post-Brexit trade friction - import delays, tariffs, and the ongoing difficulty of sourcing specific European antiques and vintage pieces - comes a close second.
On supply chain: bespoke European furniture lead times are holding at 10 to 14 weeks for the majority of respondents, though a notable proportion are quoting 14 to 16 weeks, and a handful report lead times of six months or more.
One of the most valuable findings in the survey is the collective evidence on hidden costs - the expenses that erode renovation budgets before a single piece of furniture arrives on site. Across 100 responses, several themes emerge with striking consistency.
Structural discoveries post-demolition top the list. As Anna Moss explains: “The single biggest hidden cost is structural remediation discovered after demolition - rotten or undersized joists, inadequate or non-compliant foundations that only become visible once the building is opened up.” This sentiment is echoed by dozens of respondents. London’s Victorian and Edwardian housing stock is particularly vulnerable: once walls come down, the surprises multiply.
Close behind is the cumulative cost of programme overruns. Ann-Charlotte Gerdne of Art Concepts London is direct: in London, the biggest hidden cost is time overruns - programme slippage that quietly piles up extra contractor prelims, variations, and months of rent, storage and finance costs that clients rarely budget for. Contractor preliminary costs - scaffolding, site management, skips, welfare provision, parking suspensions - are flagged repeatedly as costs that clients systematically underestimate.
“The cumulative legal and regulatory burden - building control fees, compliance paperwork, and the time delays waiting for approvals - are what clients almost never factor into their budget or schedule.”
For clients drawn to basement conversions - still one of London’s most popular ways to add space without moving - the hidden cost picture is even more severe. The survey reveals near-universal agreement: waterproofing, ventilation, structural sequencing and planning approvals are systematically underestimated. As Almas Noorani Jaffer of London Luxury Interiors puts it, the common mistake is treating it like a standard extension rather than an underground engineering project.
Perhaps the most architecturally significant finding in the survey is what is happening to the open-plan living concept that defined London home design for the past two decades.
A plurality of designers are seeing open plan give way to “broken plan” living spaces zoned with screens, levels, pocket doors, internal glazing and carefully placed joinery rather than full open vistas. A meaningful cohort report clients actively returning to traditional separate rooms. The reasons are multiple and reinforcing: post-pandemic working patterns have made acoustic separation valuable, the wellness agenda prizes quietude, and there is a growing sense that the open-plan home optimised for Instagram photography does not necessarily work for how families actually live.
“Status won’t be how big your room is, but how quiet it is.”
The kitchen and dining space remains, by a clear margin, the room commanding the highest proportion of renovation budgets. But the nature of that kitchen is changing: the survey reveals a strong emerging trend toward the “scullery revival” - a secondary utility kitchen for prep work and storage, allowing the main kitchen to remain presentable. Multiple designers independently identify the same concept: the “Marylebone Scullery Revival,” the “Dirty Functional Kitchen,” the “Quiet Luxury Utility.”
The survey offers a precise reading of where London interior aesthetics are heading in 2026 - and what they are leaving behind. Millennial Grey is the colour most designers want to ban. Its dominance is over.
The new neutral is chocolate and espresso brown - a warmer, richer, more grounded palette that aligns with the broader shift away from cool minimalism. Burgundy and oxblood are the fashionable accent choices. On materials, rough-hewn and raw timber is the standout “it” material for 2026 furniture, followed by chrome and stainless steel. Coloured glass - specifically Murano-influenced pieces is emerging as a statement material for lighting and accessories.
The dominant era influence is the 1970s revival - not the kitsch version, but what Katerina Tchevytchalova describes as “intellectual 70s with low-slung furniture, rich browns, rusts and olives and tactile materials filtered through a restrained, design-literate lens.” The buzzword for 2026, according to the largest group of respondents, is “Radical Authenticity” - a rejection of trend-led design in favour of genuinely personal spaces.
On smart home integration, the survey reveals a nuanced client picture. The largest group prefer “invisible tech” - full functionality, but hidden from sight. Screens concealed, cabling buried, interfaces minimal. A substantial cohort want full automation of blinds, lighting, heating and voice control. And “digital detox” - deliberately low-tech, mechanical-switch homes - is a growing niche, particularly among wellness-oriented clients.
The threat question divides the profession. Many believe AI will replace technical drafters and junior designers within five years. An equally vocal group are clear that AI cannot replicate human taste, empathy and the ability to navigate client relationships. The most compelling prediction may come from Anna Moss, who foresees established studios becoming “far more selective, openly turning down work that doesn’t allow for proper time” - a professionalisation of the industry that AI pressure may actually accelerate.
Running through the survey like a consistent thread is the wellness agenda. Multiple designers independently identify the same shift: clients increasingly want their homes to function as active contributors to mental and physical health, not merely as attractive backdrops.
This manifests in several concrete ways. Circadian lighting tunable systems that support the body’s natural rhythms is cited by multiple designers as a growing specification. Acoustic design is appearing in briefs. Air quality is becoming a discussion point. And the concept of designated tech-free zones within the home is emerging strongly: what Sarah Craddy calls “the digital dead zone” - the intentional shielding of primary living spaces from wi-fi and mobile coverage.
Wellness spaces themselves - home gyms, saunas, reading nooks and meditation rooms are appearing in more briefs. The prediction from several designers is that this wellness orientation will become the primary design brief within a few years, supplanting pure aesthetics as the client’s primary motivation.
Taken together, the FCI London survey paints a picture of a London renovation market in intelligent transition. The conditions are neither straightforwardly good nor bad: mortgage rates are lower, house prices are stable, and the post-pandemic impulse to invest in home has not disappeared. But the middle market is under real pressure, the regulatory environment is more complex than at any point in recent memory, and the hidden costs of London renovation - structural, temporal, bureaucratic - are running well ahead of client expectations.
The designers who are thriving are those who position themselves as strategic partners rather than aesthetic consultants: managing risk, navigating regulation, protecting clients from their own blind spots and delivering certainty in an uncertain market.
“By 2026, interior design will stop being sold on style and start being sold on certainty.”
For London homeowners considering a renovation, the data offers several clear takeaways: budget a minimum 15 to 20% contingency for structural discoveries; engage your designer before your contractor, not after; take basement conversions seriously as engineering projects; and do not assume that a falling base rate translates automatically into a cheaper project. Labour costs, material costs and the time cost of regulatory compliance are moving in a different direction entirely.
On the aesthetic question, the direction is clear: away from the generic and the algorithmic, toward the personal, the tactile and the enduring. London’s best interiors in 2026 will not be the most photographed. They will be the most lived in.
