​For years, office fit-out contractors focused much of their attention on occupiers – the businesses moving into and personalising their workspace. But that's changing.

Across the UK, landlords are becoming some of the most valuable clients in the office fit-out market, and it's easy to see why. With older buildings needing upgrades, stricter sustainability requirements on the horizon, and tenants demanding higher-quality space, landlords are investing heavily in refurbishment and Cat A fit-outs before occupiers even enter the picture.

In short, the people who own the buildings are increasingly driving the market.

The numbers tell the story

Refurbishments now account for 53% of the office development pipeline across the UK's major regional office markets, a significant increase from 41% in 2025 and just 33% in 2024. Rather than building new, owners are choosing to upgrade and reposition existing assets to meet changing tenant expectations.

London is seeing a similar trend. Around 45% of office investment (£2.8 billion) is now being directed towards refurbishment and retrofit projects rather than new developments.

And it's happening at scale. The UK interior refurbishment and fit-out market is expected to reach £9.85 billion, with Grade A office refurbishments among the strongest-performing sectors.

Taken together, these figures paint a clear picture: refurbishment is no longer a niche part of the market. It's becoming the main event.

Why landlords are spending more

ESG isn't optional anymore

One of the biggest drivers is sustainability.

Landlords are under increasing pressure to improve the energy performance of their buildings. As ESG targets tighten and EPC requirements become more demanding, older office stock risks becoming harder to let, less attractive to investors and in some cases, commercially obsolete.

For many building owners, refurbishment isn't a nice-to-have upgrade – it's an essential investment to keep assets competitive.

​

Bigger projects, bigger opportunities

From a contractor's perspective, landlord-led schemes are often larger and more comprehensive than a typical occupier fit-out.

A refurbishment project might include:

• Cat A fit-outs

• MEP upgrades

• Reception and arrival experience improvements

• Amenity space enhancements

• Sustainability and energy-efficiency measures

• Core building refurbishments

Rather than delivering a single office floor for one tenant, contractors can find themselves involved in the transformation of an entire building.

​

The race for Grade A space

While hybrid working has changed how occupiers use office space, demand for high-quality offices hasn't disappeared.

In fact, the opposite is happening. Businesses are becoming more selective and are gravitating towards modern, sustainable workplaces that help attract and retain employees.

Landlords know this and are investing accordingly. Upgraded buildings command stronger rents, attract tenants more quickly and stand out in an increasingly competitive market.

​

The rise of the "tenant-ready" office

Another interesting trend is the growing number of landlords delivering space before a tenant has even been secured.

Rather than waiting for an occupier to sign a lease, many owners are refurbishing buildings in advance, creating ready-to-occupy offices that can be marketed immediately.

For contractors, that means opportunities arrive much earlier in the building lifecycle. The decision-maker is often the landlord, not the future tenant.

It's a proactive approach that's helping owners reduce void periods and get space earning income faster.
