A research note for private investors, family offices and cross-border capital on why the UK office market should be underwritten building by building, and a framework for doing it.

Executive Summary

The UK office market in late 2026 is best understood as two markets sharing one label. Bank Rate has stayed at 3.75% through every Monetary Policy Committee decision since March, and a growing minority of members have voted to raise it. Investment volumes have been subdued, and capital values have drifted lower since the start of the year. Yet the picture beneath the average is uneven: Central London values have been broadly flat while outer-London and wider regional offices have repriced downward, and new regional supply is thin.

For investors, the implication is that "office" is not a sufficient investment thesis. This note introduces the Murivest Capital Allocation Matrix, a six-dimension tool for comparing assets, tests it against five economic scenarios, and closes with the questions to settle before committing capital. It is analysis, not advice, and every figure is attributed and dated.

The Argument: The Sector Call Matters Less Than the Selection Call

Commentary on UK offices tends to swing between two stories: structural decline driven by hybrid working, or a quality-led recovery. The evidence supports neither as a blanket statement. It supports a narrower and more useful claim: dispersion between assets has become the dominant source of risk and opportunity.

Consider what the published data show. CBRE's mid-year review reported that UK commercial real estate investment reached £23bn in the first half of 2026, down 8% on the same period of 2025, with the living and office sectors each up 7% year on year. The same review recorded values for Outer London and M25 offices falling 4.8% over the half, while Central London values held flat. Its UK Monthly Index also showed an all-property total return of 2.5% for the half, of which income contributed 2.8%, meaning capital values were a drag. (Sources: CBRE UK Real Estate Market Outlook, Midyear 2026.)

The most recent CBRE index release points the same way. UK commercial capital values fell 0.9% over the latest quarter as yields moved outward, rental values rose 0.5%, and office capital values fell 1.1% while Central London office values were flat and office rental values rose 0.7%. CBRE attributed the weakness to higher government bond yields and borrowing costs. (Source: CBRE UK Monthly Index release.)

Reading the data: Income is doing the work and capital is not. An office investor in this environment is being paid to wait, and the quality of the income decides whether waiting is rewarded.

Why Rates Still Dominate the Office Conversation

The Bank of England's Monetary Policy Committee held Bank Rate at 3.75% in March (unanimously), April (8 to 1), June (7 to 2) and July 2026 (6 to 3), with the dissenting members each preferring a rise to 4%. The July Monetary Policy Report said the path of Bank Rate would depend on how higher energy prices feed through to inflation. (Sources: March, April, June and July 2026 Bank of England summaries.) Secondary reporting indicates a further 6 to 3 hold on 17 September, with the next decision due on 5 November 2026.

For property, the relevant point is not the policy rate itself but what it signals for borrowing costs and required returns. When a building's initial yield is close to the cost of debt, leverage stops adding return. That arithmetic is shown in the worked example below, and it explains why liquidity has concentrated in assets with the most dependable income.

Two Markets: Where the Occupier Evidence Diverges From the Investment Evidence

Savills observed in its early-2026 commentary that the occupational market has been more resilient than investment activity suggests, particularly in the regional cities, where it recorded no speculative new-build starts across the Big Six in 2026 and a 25 basis point inward move in the prime regional office yield to 6.50% in February. It also estimated preliminary first-quarter UK investment turnover at £9.8bn, 41% below the five-year average for a first quarter. (Source: Savills, Market in Minutes: UK Commercial Investment.)

Colliers counted the same period differently, putting first-quarter investment at £9.3bn, 16% below the first quarter of 2025, with offices accounting for 24% of transactions and office investment of £2.5bn, below the five-year average. (Source: Colliers UK Real Estate Investment Forecasts Q2 2026.)

The two firms' totals differ because definitions, thresholds and reporting dates differ. That is not a flaw; it is a reminder that every market statistic has a methodology behind it, and a buyer should know which one before relying on a number. Likewise, Knight Frank's June 2026 yield guide reported an annualised total return of 6.33% for UK commercial property in April 2026. That figure is not comparable with CBRE's 2.5% for a six-month period, because one is annualised and the other is not. (Source: Knight Frank, UK Prime Yield Guide, June 2026.)

A Regulatory Variable Investors Cannot Ignore: Energy Efficiency

On 18 June 2026 the government published an interim response on minimum energy efficiency standards for privately rented non-domestic buildings in England and Wales. It indicated that from 2031, buildings over 1,000 square metres would be expected to reach EPC B where cost-effective, that smaller buildings would remain subject to the current EPC E minimum, and that the previously consulted interim milestone for 2027 would not be taken forward. Law-firm commentary notes that this is a confirmed policy intention rather than enacted law. (Source: GOV.UK interim response.)

For a buyer, this converts a vague "ESG" discussion into a line item. A 1,500 square metre office with a weak EPC carries a potential capital expenditure requirement that should be priced before purchase, not discovered after it.

The Murivest Capital Allocation Matrix

The Matrix is a Murivest-developed analytical tool for comparing office assets and locations on a like-for-like basis. It is not an externally validated model, it does not produce a predictive score, and it does not rank markets. It organises the questions a disciplined investor should answer, so that two different buildings can be compared on the same six dimensions.

1. Income resilience. How dependable is the contracted rent? Assess weighted average unexpired lease term (WAULT, the average remaining lease length weighted by rent), tenant covenant strength, break clauses, rent-free periods still to run and the number of tenants. Request the tenancy schedule, leases, tenant accounts and arrears ledger.
2. Entry-price discipline. Is the price supported by evidence? Compare the net initial yield with comparable transactions, reversionary potential and the replacement cost of the building. Request the valuation, comparable evidence and a purchaser's-costs calculation.
3. Financing sensitivity. How exposed is the investment to a change in borrowing costs? Test interest cover and loan-to-value under higher rates, and the refinancing risk at maturity. Request indicative debt terms and a lender-style sensitivity analysis.
4. Structural demand. Will occupiers want this specific building in ten years? Look at location, transport, specification, amenity, energy performance and the depth of local occupier demand and new supply. Request local take-up data and availability for competing buildings.
5. Regulatory and execution risk. What could delay, restrict or add cost? Consider EPC rating and MEES exposure, planning status, change-of-use potential, building safety, and refurbishment complexity. Request the EPC, planning history, surveys and any consultant reports.
6. Exit liquidity. Who buys it from you, and at what discount if conditions are poor? Consider lot size, the likely buyer universe, lease length at exit and the cost of any works needed to be saleable. Request advice on the realistic buyer pool.

Using the Matrix: Two Hypothetical Assets

The comparison below is hypothetical and illustrative. It uses qualitative judgements and deliberately avoids numerical scores, because a score would imply a precision the inputs do not support.

Neither profile is automatically better. Asset B may be the stronger investment if it is priced for its risks and a credible plan exists to extend or re-let. The Matrix does not make the decision; it shows where the decision actually sits.

Testing the Matrix Against Five Scenarios

Worked Example: Why the Headline Yield Is Not the Return

The following is a hypothetical illustration with stated assumptions. It is not a forecast and does not describe any Murivest opportunity.

Assumptions: purchase price £10,000,000; net rent £700,000 a year; Stamp Duty Land Tax calculated on the non-residential rates (nil to £150,000, 2% from £150,001 to £250,000, 5% above that, per GOV.UK); agent fee 1%; legal fee 0.5%; VAT at 20% on those fees.

• SDLT: £2,000 + 5% of £9,750,000 = £489,500
• Agent £100,000, legal £50,000, VAT on fees £30,000
• Total purchaser's costs: £669,500 (about 6.7%); all-in cost £10,669,500
• Net initial yield = £700,000 ÷ £10,669,500 = 6.56%, not the 7.00% a quick calculation on price alone would suggest

The leverage test. Assume £5,000,000 of interest-only debt, leaving equity of £5,669,500. At an interest rate of 6.0%, interest is £300,000, cash after interest is £400,000 and the cash yield on equity is about 7.06%, above the 6.56% unlevered yield, so debt adds income. At 7.0%, interest is £350,000, cash after interest is £350,000 and the cash yield on equity is about 6.17%, below the unlevered yield, so debt now dilutes income. The example ignores vacancy, capital expenditure, tax and amortisation, all of which would reduce the figures further.

The lesson is simple. Where the net initial yield and the cost of debt are close, a small rate move changes the character of the investment.

Location Analysis: London, Manchester and Birmingham Through the Matrix

The Matrix applies to locations as well as buildings, but a location is only a starting point. The notes below describe the questions each market raises, not a ranking or a recommendation.

London. The largest and deepest buyer pool supports exit liquidity, and Central London values have held flat in the data cited above. The key questions concern entry-price discipline, because quality is widely recognised, and the difference between Central London, fringe and outer-London stock. Murivest's London market page sets out its advisory coverage.

Manchester. Regional offices combine thin new supply with a smaller buyer pool than London. The key questions are specification, EPC, and how deep local occupier demand is for the particular building. See Murivest's Manchester market page.

Birmingham. Another large regional centre with its own occupier base. The same discipline applies: building quality, lease profile and exit. See Murivest's Birmingham market page.

Representative Opportunities on the Murivest UK Platform

Murivest's UK platform shows representative opportunities across its coverage. These illustrate the type of mandate Murivest works on. They are not offers, and the availability, price and terms of any asset must be confirmed in writing under mandate and NDA before any decision is made.

REPRESENTATIVE: London Office

Location: London

Indicative size shown: £100m, 10-year WAULT

Status shown: Private / Off-market

Applying the Matrix, a 10-year WAULT is a strong starting point for income resilience, but the investor should still ask who the tenants are, whether any break clauses sit within that term, and what the all-in net initial yield is after purchaser's costs. "Off-market" means the asset is not broadly marketed; it does not mean it carries less risk, and the same due diligence applies.

ALSO REPRESENTATIVE: Manchester Industrial and Logistics

Location: Manchester

Indicative size shown: £100m, 8% net initial yield

Status shown: Public opportunity

ALSO REPRESENTATIVE: Birmingham Retail

Location: Birmingham

Indicative size shown: £100m, 8% passing yield

Status shown: Public opportunity

The two quoted yields are not the same measure. A net initial yield deducts purchaser's costs from the return, whereas a passing yield is typically calculated on the rent currently payable relative to price. A buyer comparing the two must put them on the same basis first.

Ten Questions to Settle Before Pursuing an Office Acquisition

1. What is the net initial yield after full purchaser's costs, and on what rent?
2. How much of the rent is contracted beyond the first break, and who are the tenants?
3. Is the passing rent above or below current market rent?
4. What is the EPC rating, and what would an upgrade to EPC B cost for this building?
5. What is competing supply in this location, and is it Grade A or secondary?
6. How does the investment perform at interest rates one to two percentage points higher?
7. What capital expenditure is needed in the first five years, and who has costed it?
8. Who is the likely buyer at exit, and what lease length will they want?
9. What is the return in your home currency, and what would hedging cost?
10. Which parts of this analysis rely on information you have not independently verified?

Frequently Asked Questions

Is UK office space a good investment in 2026?

It depends on the asset. Published data show Central London office values holding flat while outer-London and regional offices repriced lower in the first half of 2026, so building selection matters more than the sector label. This is general information, not advice.

What is a good yield for a UK office investment?

There is no single good yield. Savills reported a prime regional office yield of 6.50% in February 2026, but a yield must be judged against tenant strength, lease length, capital expenditure needs and financing costs. Always compare net initial yields on a like-for-like basis.

How do interest rates affect UK office values?

Higher borrowing costs and government bond yields tend to push property yields outward, which reduces capital values. CBRE linked recent capital value falls to exactly this effect.

What does EPC B by 2031 mean for office owners?

The government has indicated that privately rented non-domestic buildings over 1,000 square metres would be expected to reach EPC B from 2031 where cost-effective. This is a policy intention, not yet law, so buyers should price potential upgrade costs and monitor legislation.

Can overseas investors buy UK office buildings?

Yes, subject to legal, tax and compliance requirements, including registration of overseas entities with Companies House before buying. Our companion guide, How to Buy Commercial Property in the UK, covers these in detail.

Methodology and Limitations

This note was prepared on 11 October 2026 using publicly available sources, each cited where used. Market data are drawn from CBRE, Savills, Colliers and Knight Frank publications covering the periods stated; Bank of England decisions are taken from the Bank's published summaries; tax rates are taken from GOV.UK. Different research houses measure investment volumes and returns differently, so figures are not directly comparable across sources and some totals disagree. Forecasts are not provided, and no scenario in this note is a prediction.

The Murivest Capital Allocation Matrix is an internally developed analytical framework. It has not been independently validated, is not industry-standard and does not generate a statistically predictive score. Worked examples are hypothetical. Murivest was established in 2025 and does not claim a track record in this market beyond what it can evidence. Search-interest context for this topic was informed by a 24-hour Google Trends sample (11 to 12 May 2026) in which "office space" was the most searched of seven related terms; that sample is a directional topic signal only and is not used as market evidence.
