St Albans is one of the least affordable districts in England, with homes costing roughly 15 to 17 times local earnings in recent official measures. That gap between property values and incomes is exactly why estate planning here looks different from the national average.
The affordability ratio comes from the Office for National Statistics, which put St Albans among the least affordable places outside central London, with prices around 15.5 times workplace earnings (ONS, Housing affordability in England and Wales, 2024, subject to change). For inheritance tax the practical point is simpler: a large share of local estates is carried by the home itself, and many of those homes have quietly grown past the thresholds that decide whether tax is due.
Where a typical St Albans estate sits against the thresholds
Inheritance tax is charged at 40% on the part of an estate above the tax-free bands (gov.uk, as at July 2026, subject to change). One person has a £325,000 nil-rate band, plus a residence nil-rate band of up to £175,000 where a home passes to children or grandchildren, giving up to £500,000. A couple can combine both sets, reaching up to £1,000,000 where a home passes to direct descendants.
Set the local numbers against those lines. The average St Albans home at £638,000 (ONS, May 2026, subject to change) already exceeds the £500,000 that one person could shelter with a home left to descendants, by around £138,000. For a married couple or civil partners the same home still falls within the combined £1,000,000, so the home alone is unlikely to create a bill on the second death. The pressure usually comes from everything sitting on top of it: pensions now within scope for many estates, investment portfolios, and second properties are common in this part of Hertfordshire.
Because the nil-rate band and residence band are frozen until the end of the 2030-31 tax year (5 April 2031) (gov.uk, subject to change), St Albans values rising at 3.0% a year steadily lift more estates over the line while the allowances stand still. What looked comfortably within the bands a few years ago may not be by the time an estate is administered.
The £2 million taper is the live question here
For higher-value St Albans estates the detail that matters most is the residence nil-rate band taper. That £175,000 residence band is reduced by £1 for every £2 by which the estate exceeds £2,000,000 (gov.uk, residence nil-rate band, as at July 2026, subject to change). Cross the £2m mark and the very allowance that a family home was meant to attract begins to disappear.
The withdrawal is faster than many people expect. On one person's £175,000 residence band, the taper removes it entirely once the estate reaches about £2,350,000. Where a surviving spouse holds two residence bands worth £350,000 between them, the full amount can be withdrawn by roughly £2,700,000. In a district where a family home may be worth well over a million on its own, an estate holding that home plus pensions and investments can reach the taper zone without anyone feeling wealthy in cash terms. This is general information rather than a calculation for any particular estate, and the figures are subject to change.
The taper is also why the order and timing of gifts, the way a home is left, and the use of trusts tend to matter more for St Albans owners than for families in lower-value areas. Bringing an estate back below £2,000,000, or keeping it there, can restore residence band that the taper would otherwise take. Whether that is achievable, and sensible, depends entirely on individual circumstances and is a question for advice rather than a rule of thumb.
Detached homes and the couple's allowance
The district's housing mix sharpens the point. In May 2026 the average detached home in St Albans stood at £1,224,000, with semi-detached at £758,000 and terraced at £569,000 (ONS, St Albans, May 2026, subject to change). A detached St Albans home therefore exceeds the £1,000,000 combined couple allowance on the property alone, before a single pension, ISA or second home is counted.
For owners of these homes the planning conversation is rarely about whether inheritance tax could arise, and more about how much, when, and what can reasonably be done in advance. Domicile and the location of assets can matter for families with international ties, which are not unusual in the commuter belt. Trusts are sometimes used to hold assets for children or grandchildren with more control over timing. And lifetime gifting, made early enough to fall outside the estate, is one of the more direct levers, though it carries its own rules and trade-offs that need to be weighed for each family.
