RICS Red Book valuations accepted by HMRC








Probate work needs a steady hand. Our RICS-qualified valuers carry out probate valuations across Letchworth, from SG6 1 to the older Garden City streets around the conservation area. We provide HMRC-compliant figures at the open market value on the date of death, so executors have a report they can rely on when dealing with inheritance tax and estate administration. The process is clear, discreet and written for the people who have to make decisions at a difficult time.
Local price gaps can be wide, even within the same postcode sector. homedata.co.uk records show an average Letchworth house price of £441,383 over the last 12 months, with detached homes at £669,092 and flats and apartments at £187,569. We look at comparable sales, the property’s condition and the likely buyer market before issuing a Red Book valuation that stands up to scrutiny.

A probate valuation is the open market value of the property at the date of death, written in a format HMRC can use. Our valuers prepare the figure under RICS Valuation - Global Standards, often called the Red Book, because a probate file needs evidence rather than a quick opinion. That distinction matters if the estate includes a house in SG6, a flat in the town centre or a larger home on a more private plot. The final number is based on market reality on the relevant date, not on what the family hopes the property might fetch later.
Estate agent appraisals can be useful background, but they are not the same as a probate valuation. An asking price is shaped by marketing strategy, while a probate figure has to reflect the open market value at a fixed point in time. Letchworth’s mix of red brick homes, rendered houses, tile-hung details and timber features means two nearby properties can sit in different price bands. Our role is to separate appearance, condition and location from sentiment, then set out the evidence in plain English.

homedata.co.uk records show 336 home sales in Letchworth over the last 12 months, which gives our valuers a solid base of local evidence. Of those sales, 79 were detached homes, 71 were semi-detached, 115 were terraced and 71 were flats or apartments. That mix matters in probate work because a family home in the original Garden City streets will not be valued in the same way as a newer flat or a detached property on a larger plot. We compare the right property type, the right street pattern and the right condition profile before setting a figure.
Price movement has also been uneven by property type. Detached homes showed a 3.3% change, semi-detached homes rose by 9.2%, terraced homes moved by 4.8% and flats fell by -4.4% over the last 12 months. homedata.co.uk also records that house prices in the SG6 4 postcode sector grew by 1.1%, while SG6 1 fell by -3.4% in the same period. Those gaps are exactly why a probate estimate should not be lifted from a broad town average.
Letchworth Garden City was founded in 1903, and that history still shapes the housing stock we inspect today. Active new-build schemes such as Knights Park, Letchworth Gate and The Templars in SG6 1AN sit alongside older homes from the pre-1919, 1919-1945 and post-1945 periods. Large parts of the town also fall within a Conservation Area, with Listed Buildings spread across the original layout. A probate valuation here has to reflect age, construction and setting, not just bedroom count.
Executors usually need a probate valuation as soon as they start handling the estate, because the figure is needed for the inheritance tax return and the Grant of Probate process. If the estate value is above the nil-rate band, or if there is a home passing to direct descendants, the residence nil-rate band may also be relevant. We regularly advise families where the property is in joint ownership, where there are two homes to value, or where the deceased left a house in Letchworth and another asset elsewhere. Each case needs the same disciplined approach.
The need can arise even when the family does not plan to sell straight away. HMRC wants the value at the date of death, not the later sale price, so an executor should not wait until the market has moved before getting the report done. In a town with older homes, conservation controls and listed properties, that timing helps keep the estate file organised from the start. Our valuers set out the evidence early, which reduces avoidable questions later.

The executor, solicitor or family member sends us the address, the date of death and any relevant notes about ownership or access.
Our valuer visits the property, checks the accommodation, looks at visible defects and notes anything that could affect value in Letchworth.
We compare recent local sales, including homes in SG6 1 and SG6 4, then weigh that evidence against the property type and condition.
The valuation is written in Red Book format with the market evidence, the date of death figure and the assumptions we have relied on.
We send the report, usually within 5-7 working days, so the executor can use it for the IHT return and estate paperwork.
If the property is sold later, the probate figure provides a clear reference point for solicitors, accountants and beneficiaries.
The nil-rate band for inheritance tax is £325,000 per person, frozen until April 2028. The residence nil-rate band adds £175,000 per person where the home passes to direct descendants, and married couples or civil partners can often transfer unused allowances. That means the tax position for a Letchworth estate can change sharply depending on ownership, will wording and whether the property is left to children or grandchildren. A correct probate valuation is the starting point for the whole calculation.
Property value can tip an estate over a threshold faster than many families expect. With the town average at £441,383, and detached homes at £669,092, a single house in Letchworth can take a large share of the estate allowance before bank accounts, investments and personal possessions are even counted. The figures in SG6 4 and SG6 1 also show that street-level value is not uniform, so the right date-of-death valuation matters. We often see estates where a careful Red Book report changes the tax picture and the paperwork that follows.
Executors have 12 months from the date of death to submit the inheritance tax return, and HMRC can challenge valuations within 4 years. That is why we keep our reports clear, evidenced and easy to file away with the rest of the estate records. If the home is in the conservation area or on older ground with clay soils, we note any issues that may have influenced market value. A valuation that explains its reasoning is much easier to defend if HMRC asks questions later.
homedata.co.uk records 336 sales in the last 12 months, so there is a real transaction trail for our valuers to study when a probate sale is likely. Terraced homes accounted for 115 of those sales, while detached homes made up 79, semi-detached homes 71 and flats 71. That spread helps us judge how a property is likely to perform if the estate later decides to sell. It also means we can spot when a probate figure is drifting away from what the local market has actually done.
Letchworth’s building stock brings its own considerations. Red brick, render, tile-hanging and timber features are common, and the underlying chalk with clay-with-flints or glacial till can leave some homes exposed to shrink-swell movement. Surface water flooding can also appear in localised spots after heavy rain, even though the town is not generally treated as a high river or coastal flood area. If the executors decide to sell, our conveyancing support can help move the matter on, and any uplift above the probate value may create capital gains tax questions for the estate.

HMRC needs a date-of-death market value so the inheritance tax return and estate accounts are accurate. A probate valuation gives the executor a figure that can be defended if the estate is reviewed later. Our RICS-qualified valuers write that figure in Red Book format, which is the standard HMRC expects.
Our fees start from £250 for straightforward homes. Larger detached properties, listed buildings and homes with more complex access or title arrangements can cost more because they take longer to inspect and research. We always explain the quote before the booking is confirmed.
Yes, provided it is prepared by a suitably qualified valuer to RICS Valuation - Global Standards. HMRC is looking for a defensible figure backed by comparable evidence, not a casual estimate. Our reports are written with that requirement in mind, which helps keep the probate file tidy.
The visit itself is usually straightforward, but the full report normally takes 5-7 working days. Homes in the conservation area, listed buildings or properties with access restrictions can take a little longer if extra evidence is needed. We keep the executor updated if that happens.
The nil-rate band is £325,000 per person, frozen until April 2028. The residence nil-rate band is £175,000 per person where a home passes to direct descendants, and unused allowances can often be transferred between spouses or civil partners. In Letchworth, a property valued at £441,383 can make the calculation much more sensitive.
An estate agent's figure can help with marketing, but it is not the same as a probate valuation. HMRC wants the open market value at the date of death, supported by methodical research and a Red Book report. We often see the difference most clearly on homes in SG6 1 and SG6 4, where street-by-street values can shift.
That does not stop a probate valuation, but it can affect the evidence we review and the value we assign. Listed Buildings, older brick homes and properties with render or timber details often need extra care in the report. We note those factors clearly so the executor understands how the figure was reached.
Our probate valuation fees start from £250, which covers the inspection, local comparable research and the Red Book report. The report sets out the open market value at the date of death, the evidence used and any assumptions that affect the figure. For a family dealing with an estate in SG6, that clarity is often more useful than a short verbal estimate. It gives the solicitor, accountant and executor a single reference point.
Straightforward terraced homes usually sit at the lower end of the fee range, while detached properties, listed buildings and homes with unusual construction can take more time. In Letchworth, older properties around the original Garden City layout often need extra attention because of conservation area controls, building materials and age-related defects such as damp, roof wear or movement linked to clay soils. We keep the process practical and direct, with no hidden steps. Once the inspection is complete, the usual turnaround is 5-7 working days.
The valuation package is built for probate, not for marketing. That means the report is written to HMRC standards, with a date-of-death value and enough detail to support the estate if questions come up later. If the property is sold after probate, the figure also gives the family and their solicitor a clear baseline for any later tax or accounting calculations. For executors managing a Letchworth estate, that paper trail can save time at a busy point.
