Probate Valuation in London

HMRC requires that all property included in a deceased person's estate is valued at its open market value as at the date of death. In London, this is not a straightforward exercise. The capital's property market is hyper-local - a two-bedroom flat in Bermondsey might sell for considerably more or less than an equivalent property in nearby Elephant and Castle, depending on the specific street, floor level, and building condition. Generic online estimates rarely capture these nuances, and HMRC does not accept automated valuations as formal probate evidence.

A RICS probate valuation provides a defensible, professional opinion of open market value that HMRC will accept. If an estate is challenged - either because HMRC suspects undervaluation or because beneficiaries dispute the figures - a RICS report provides the legal standing to support the reported values. Our assessors maintain detailed records of comparable sales evidence and document their reasoning, giving executors full protection against personal liability.

London property values have shifted considerably in recent years. Rightmove reported an overall average asking price of £656,619 over the last year, down 8% from the previous year and 11% below the 2023 peak of £735,637. For inheritance tax calculations, the specific date-of-death value matters enormously, and only a qualified surveyor with access to contemporaneous comparable evidence can establish this with the precision HMRC expects.

• Required for IHT400 and IHT405 forms submitted to HMRC
• Necessary to obtain a grant of probate from the Probate Registry
• Protects executors from personal liability if values are later challenged
• Used to calculate any capital gains tax on subsequent sale
• Required for properties held in trust or jointly with another party

Probate in England and Wales follows a defined legal process, and London estates add layers of complexity that executors must navigate carefully. If the deceased owned a London property - whether a leasehold flat, a share of freehold house, or a long lease in a purpose-built block - this must be disclosed to HMRC as part of the estate valuation. London's prevalence of leasehold properties makes this particularly relevant, as the length of the remaining lease directly affects value and must be reflected in the probate report.

Our surveyors assess each property individually. For a typical London terraced house in a borough like Islington or Hackney, the surveyor visits the property, notes its condition relative to local comparables, reviews Land Registry transaction data, and applies professional judgment to arrive at a figure reflecting what a willing buyer would have paid on the open market on the date of death. The assessment accounts for structural condition, decorative state, and any short-lease implications where relevant.

Where an estate includes multiple London properties - common among landlords or those who inherited property themselves - we offer discounted multi-property rates. Each property receives a full RICS report, but the site visit and comparable research efficiency improves across a portfolio. Executors managing complex estates with several flats across different boroughs can instruct us once and receive coordinated reports for all properties within the same timeframe.

• Inspect the property at a time convenient to the executor or occupant
• Research comparable sales in the immediate area around the date of death
• Assess condition and any factors affecting open market value
• Produce a written RICS report with supporting comparable evidence
• Deliver the report to the executor within 5-7 working days
• Follow-up support available if HMRC queries the valuation

London's housing stock is unlike anywhere else in the UK. The capital contains 2.92 million housing units spanning nearly four centuries of construction. Around 12.6% of properties were built before 1900, predominantly in central and inner boroughs. Kensington and Westminster hold the highest concentration of pre-1900 housing, with nearly one in four properties in those areas dating from the Victorian era or earlier. These buildings require careful assessment - their value reflects both the scarcity of period stock and the ongoing cost of maintenance, which can be substantial in listed or conservation area properties.

The inter-war period (1930-1949) accounts for 20% of London's housing stock, concentrated in outer boroughs like Lewisham, Walthamstow, and Harrow. These properties were largely built with London Stock Brick, timber floors, and solid wall construction. They frequently present issues with dampness, original single-glazed windows, and outdated electrical systems - all of which affect open market value and must be reflected accurately in a probate valuation. Our assessors know these property types well and price their conditions correctly.

Post-war housing (1950-1982) accounts for around 24% of London's stock, with a significant proportion in purpose-built estates and early high-rise blocks. Leasehold complexities, cladding assessments following the Grenfell inquiry, and EWS1 certification requirements have added significant uncertainty to the valuation of flats from this era. Our surveyors are trained to navigate these issues and reflect them appropriately when calculating estate values.

Modern properties built after 1996 make up just over 12% of London's housing stock, concentrated in regeneration zones like Canary Wharf (E14), where nearly 53% of units were built after 1996, Royal Docks (E16), Bermondsey (SE16), and Stratford (E15). New-build valuations for probate are generally more straightforward but still require a registered valuer - developer price lists are not acceptable to HMRC as standalone evidence of open market value.

London remains the least affordable region in Britain, with the average home costing 13.9 times the typical annual salary. This price-to-income ratio means a significant proportion of London estates trigger inheritance tax. The current nil-rate band is £325,000, and the residence nil-rate band adds a further £175,000 when a family home passes to direct descendants - giving a combined threshold of £500,000 for most qualifying estates. With London averages comfortably above this for detached houses, semis, and terraces, inheritance tax is a near-certainty for many London executors.

Flat values have declined more sharply than houses in London - flats averaged £430,000 in December 2025, down 3.6% annually - while semi-detached houses rose 2.9% to an average of £715,000. This divergence means the property type within an estate significantly affects the IHT calculation. Our probate reports document not just the headline value but the specific characteristics that support it, giving HMRC everything needed to process the IHT return without follow-up requests for additional evidence.

• Properties above £325,000 likely create some inheritance tax liability
• The residence nil-rate band requires the property to pass to direct descendants
• Jointly-owned properties require a discount for the co-ownership element
• Properties in trust require specialist valuations under different HMRC rules
• A RICS report date-stamped to the date of death is the standard HMRC expects
