Estate planning accountants
in London

London holds the highest residential property values in the UK by a wide margin, and that single fact reshapes inheritance-tax planning here more than anything else. Across large parts of inner and west London, an ordinary family home bought decades ago is now worth well over £1m, so estates that feel modest to the people who own them routinely sit above the nil-rate band before any savings, investments, or pension pots are even counted. The result is that London has the largest concentration of estates over the inheritance-tax threshold of any region, and many of those estates belong to people who have never thought of themselves as wealthy. Their wealth is the house they live in, not liquid assets they can rearrange easily.

Because so much value is tied up in property, the residence nil-rate band matters a great deal here, and so does the taper that quietly removes it. The residence nil-rate band adds £175,000 of relief on a home left to direct descendants, but it is reduced by £1 for every £2 an estate exceeds £2m. In a city where a family home plus a pension and some investments can push a single estate past £2m without much effort, that taper is not a remote concern for the very rich. It is a live issue for a great many London households, and the loss of relief is gradual and easy to miss until the estate is being administered.

London also has the country's deepest concentration of international and cross-border estates. Many residents hold property or other assets abroad, have moved to the UK from elsewhere, or have family spread across multiple countries. The way someone is treated for UK inheritance tax now turns on long-term residence rather than the older domicile concept, and that change interacts with overseas assets, foreign wills, and double-tax treaties in ways a generalist will often handle only occasionally. A specialist estate-planning accountant who works with internationally connected families regularly is far better placed to spot where a foreign will conflicts with an English one, or where an overseas asset creates an unexpected UK charge.

Layered planning is more common in London than anywhere else in the UK, partly because estates are larger and partly because the supply of specialist advisers is deep. A typical London estate plan might combine a will using both nil-rate bands, lifetime gifting to use the seven-year rule, trusts for younger or vulnerable beneficiaries, charitable legacies to bring the rate down to 36%, and careful sequencing of pension drawdown ahead of the April 2027 change that brings unused pension funds into the IHT net. Each element interacts with the others, and getting the order and timing wrong can waste reliefs that cannot be recovered later.

London is also where family businesses, investment companies, and property portfolios most often sit inside a single estate. The Business Relief and Agricultural Relief rules tighten from April 2026 to a combined £1m cap at 100% relief, with 50% relief above that, so owners of trading businesses and qualifying land in and around the capital now need to plan around a ceiling that did not previously bite. For families whose business is worth several million pounds, that is a material shift, and it rewards early, specialist planning rather than a review left until illness or death forces the issue.

Specialist estate-planning advice matters in London first because the sheer size of estates makes mistakes expensive. At 40%, every £100,000 of value that could have been sheltered but was not costs £40,000 in tax. In a city where the home alone often crosses the threshold, the difference between a plan that uses both nil-rate bands and the residence nil-rate band correctly and one that does not can run into hundreds of thousands of pounds on a single estate.

The £2m taper makes London a place where general advice frequently falls short. Many households here sit just either side of that line, and small decisions, such as how a pension is drawn, whether a gift is made, or how a business interest is valued, can determine whether £175,000 of residence relief survives or is tapered away. A specialist who models the estate around the taper, rather than treating the residence nil-rate band as automatic, protects relief that a generalist may assume is simply available.

Finally, London's international and multi-generational families need advisers who handle cross-border estates as routine work, not as an exception. Foreign property, overseas beneficiaries, long-term-residence questions, and conflicting wills across jurisdictions all create traps that an occasional adviser will not have seen often. We handle this kind of estate as day-to-day work, so the complexity is met with genuine familiarity rather than a first attempt.
