What is this report?

The Digital Readiness Report, Central London, is a practical guide to digital infrastructure for commercial buildings. It looks at seven boroughs: the City of London, Westminster, Camden, Islington, Kensington and Chelsea, Lambeth, and Southwark. Together, these areas contain 116,660 commercial properties, including 58,740 office spaces.

The report shows how digital performance now affects leasing, risk and asset value. It looks at the gap between buildings that are ready for modern occupier needs and buildings that are falling behind. It also sets out what property teams can do next.

Why this matters

Digital infrastructure is no longer just a technical issue. It affects tenant demand, day-to-day operations, compliance, resilience and long-term value.

The report points to a clear split in the market. Buildings with strong connectivity, strong mobile coverage, smart building capability and clear proof of performance can win a digital premium. Buildings with weak infrastructure, poor energy performance or unmanaged digital risk can face delay, cost and a weaker market position.

This matters now because occupier expectations have moved on. The report notes that connectivity now ranks as the second most important factor in commercial leasing decisions, ahead of price. It also shows that a majority of UK businesses are willing to pay premium rents for robust connectivity.

Who this report is for

  • Property owners and landlords
  • Asset managers and investors

What the report covers

The report covers the issues that now shape digital readiness in commercial property.

  1. The Central London market
    It starts with the scale and economic weight of Central London commercial property and why these seven boroughs matter.
  2. The digital premium and brown discount
    It explains how strong digital performance can support rent, occupancy and lease length, while weak performance can drag on competitiveness.
  3. Connectivity infrastructure
    It looks at full fibre availability, take-up, and where there is still room to upgrade buildings.
  4. Mobile coverage inside buildings
    It looks at indoor 4G and 5G expectations and why building materials and design still matter.
  5. Energy efficiency and MEES risk
    It covers EPC performance, the brown discount, and why energy and digital performance now sit side by side in the market.
  6. Security and cyber risk
    It looks at exposed devices, supplier risk and the wider cyber picture for buildings and connected systems.
  7. WiredScore and SmartScore certification
    It shows where certification is already present, where there is white space, and why third-party proof matters.
  8. Borough level scoring
    It includes a scoring method across connectivity infrastructure, mobile coverage, energy efficiency, security posture and certification status.
  9. The business case for investment
    It sets out the financial case for action, including rental premium, lower vacancy, longer lease terms and asset value impact.
  10. Professional obligations and next steps
    It links digital readiness to the RICS Digital Risks in Buildings framework and gives practical recommendations.

Business case snapshot

The report makes the financial case for robust digital infrastructure and connectivity in plain terms.

For a typical 50,000 sq ft Central London office, it points to the following:

£146,250 in additional annual rent from a 4.5% digital premium midpoint
£1,462,500 in added revenue over 10 years
£123,500 in annual vacancy cost savings
£225,000 saved through fewer turnovers over 10 years
£2,922,500 in total 10-year benefit

The report also says that even more advanced digital infrastructure upgrades often sit in the range of £200,000 to £500,000 for a building of that size. That frames digital investment as a serious business case, not a nice-to-have.
