RICS Red Book valuations accepted by HMRC








Probate work starts with a date, not a sale price. Our RICS-qualified valuers carry out probate valuations across Horsham, giving executors an open market value at the date of death that HMRC can review against the estate account. We work to the RICS Valuation (Global Standards), often called the Red Book, because a probate figure needs to be defensible, not guessed. For families dealing with a death, that clarity helps a difficult process feel more orderly.
Horsham has a wide spread of housing, from listed homes around the town centre conservation areas near Market Square and the Causeway to post-1980 houses in RH12 4SE. homedata.co.uk records show an overall average house price of £525,845, with detached homes at £822,544 and flats at £252,536, so small differences in condition can shift a probate figure by a large amount. We also know the local stock includes clay-built and older properties that can show movement or damp, which makes a site inspection far more reliable than a desk-based estimate. Good evidence matters because HMRC can question a return later, and executors are the ones who must stand behind the number.

A probate valuation is the open market value of a property at the date of death. That figure is used for inheritance tax and for the estate records, so it must reflect what a willing buyer would have paid in Horsham on that date, not what the family hopes the home will achieve after probate. A Victorian terrace near Market Square, a semi in a newer part of RH12, and a flat off the Causeway can all produce different values even if they sit in the same postcode area. Our valuers look at condition, tenure, local comparables and any factor that would matter to a buyer.
An estate agent's appraisal is built for marketing, while a Red Book report is built for HMRC scrutiny. That difference matters in Horsham because older streets in the town centre conservation areas can include listed buildings, altered layouts and maintenance issues that a brief market appraisal may not explore in enough depth. Our RICS team records the evidence behind the figure, including photos, comparable sales and any obvious defects such as damp or movement. If HMRC ever asks why the number was used, the report gives executors a clear paper trail.

The local market gives probate valuations real context. homedata.co.uk records show Horsham's overall average house price at £525,845, with detached homes at £822,544, semi-detached homes at £465,566, terraced homes at £391,373 and flats at £252,536. The 12-month change is -2.3% overall, with detached at -2.8%, semi-detached at -1.7%, terraced at -1.8% and flats at -3.8%. There were 1,061 property sales in the last 12 months, so our valuers can build a report on actual local movement rather than guesswork.
Horsham District has a population of 149,500, with 62,500 households recorded in the 2021 Census. The housing mix is split across detached homes at 33.6%, semi-detached at 30.5%, terraced at 18.2% and flats or maisonettes at 17.1%, which tells us why a probate valuation in the same street can still vary by house type. Age matters too, because 13.5% of homes are pre-1919, 11.0% date from 1919-1945, 31.0% from 1945-1980 and 44.5% post-1980. That spread creates very different inspection priorities, from solid walls and timber defects in older homes to condensation and workmanship issues in newer ones.
Local economics also feed into buyer behaviour. Horsham benefits from financial services, professional services, advanced engineering and pharmaceuticals, while RSA Insurance Group, The Body Shop headquarters and firms linked to the Gatwick Airport catchment area all support housing demand. That matters for probate because executors often need to know whether a detached home on the edge of town, or a flat closer to the centre, sits in a stronger pool of buyers. A valuation backed by local evidence is easier to defend than a generic regional estimate.
Executors usually need a probate valuation when they apply for Grant of Probate or deal with inheritance tax. If the estate is above the threshold, or if a property forms a major part of the estate, HMRC wants the open market value at the date of death, not a later asking price. In Horsham, that can apply to everything from a terraced house near Market Square to a detached home in RH12 4SE or a flat in one of the newer developments. Executors also have 12 months from death to submit the IHT return, so early evidence helps keep the paperwork moving.
Jointly owned property, multiple properties and rental homes can all bring extra steps. A house near the Causeway, a cottage by the town centre conservation area, or a property that sits close to Boldings Brook may need closer review if there are flood, drainage or movement concerns. HMRC can also review the valuation later, up to 4 years, so a rushed figure can become expensive to defend. Our valuers give executors a report that fits the probate file, the estate accounts and any future sale.

We take the property address in Horsham, the date of death and any known issues from the estate paperwork. If the home sits in RH12 4SE or in the town centre conservation area, we note that from the start.
A qualified valuer visits the property and checks the visible condition, layout and saleability. Older houses with red brick, tile hanging or timber features often need a slower inspection, especially where damp or movement is suspected.
We compare the home with sold evidence from homedata.co.uk and, where relevant, current market context from home.co.uk. That includes houses around Market Square, the Causeway and other Horsham streets with similar age and type.
We factor in subsidence risk from Weald Clay, drainage problems, roof wear, timber decay and any flood exposure from the River Arun, the River Adur or Boldings Brook. The report reflects how buyers would react to those points on the date of death.
Our RICS team produces a formal report with the valuation figure, supporting evidence and the reasoning behind the number. Executors can place it with the probate papers and share it with solicitors or accountants.
The probate value supports the IHT return, the estate accounts and any later sale. If the property is sold after probate, the same figure also helps calculate any gain from the date of death onward.
The inheritance tax rules are fixed, but the property value can change the outcome sharply. The nil-rate band is £325,000 per person and is frozen until April 2028, while the residence nil-rate band is £175,000 per person where the home passes to direct descendants. Married couples and civil partners can usually transfer unused allowances, which can reduce the tax position on the second death. For a Horsham estate, the probate valuation is the figure HMRC uses to measure the estate against those thresholds.
A detached house at £822,544 is already well above the standard nil-rate band, so the valuation needs to be strong from the start. Even a flat at £252,536 can sit close to the point where other assets push the estate into tax territory once savings, investments or a second property are added. Our valuers also look at issues such as Weald Clay movement, damp, flood risk and conservation restrictions around the Causeway and Market Square, because those factors can affect what a buyer would pay on the date of death. If an estate needs to be defended later, the evidence behind the figure becomes just as important as the figure itself.
Some estates include more than one property, and Horsham households often do. A family home in the district, a buy-to-let near the centre or a recently built house in RH12 4SE can all be part of the same return, and each asset needs its own defensible value. Our reports help solicitors, accountants and executors keep the numbers aligned. That reduces the risk of disagreement when the estate is being finalised.
Probate sales in Horsham often start with a realistic view of the local market. home.co.uk currently lists active new homes at Highwood Green and Broadacres in RH12 4SE from £499,995 to £799,995, The Maples from £374,995 to £649,995 and Orchard Gate from £549,950 to £999,950. Those developments sit alongside older homes in the town centre, so the sale route depends on age, condition and buyer demand for the type of property in question. A valuation that already reflects local comparables makes the next step easier for the estate.
If the estate sells after probate, capital gains tax uses the probate value as the starting point, not the original purchase price. That is one reason executors in Horsham need a sound date-of-death figure before marketing a home near Market Square, the Causeway or one of the newer developments on the edge of town. homedata.co.uk records show 1,061 sales in the last 12 months, which gives us a solid evidence base when we assess how quickly similar homes are moving. The same evidence can also help solicitors decide whether to sell straight away or wait for a better moment.
Our team can also support the sale side. We can connect executors with conveyancing, survey and EPC support so the estate is ready for marketing, listing and completion. That matters where the house has older features, a clay-related movement issue or flood exposure near the River Arun, the River Adur or Boldings Brook. Probate work is often time-sensitive, so keeping the process joined up saves repetition for families.

HMRC needs the property's open market value at the date of death so the estate can be assessed correctly. In Horsham, that figure may differ a lot between a flat at £252,536 and a detached home at £822,544, so a generic estimate is rarely enough. Our RICS-qualified valuers provide a Red Book report that executors can rely on when completing the estate paperwork.
Our probate valuations start from £250 in Horsham. The fee depends on the property's size, complexity and whether the home is in a conservation area around Market Square or the Causeway. For many straightforward homes, the figure covers inspection, analysis and a formal written report.
HMRC accepts valuations that are prepared to RICS Valuation (Global Standards) and supported by proper evidence. Our reports set out the sold comparables, the condition of the property and any local factors such as Weald Clay movement or flood exposure. If HMRC queries the figure later, the report gives executors a clear paper trail.
Most valuations are completed within 5-7 working days, although older homes or properties with unusual features can take longer. A listed building in the town centre or a house near Boldings Brook may need extra review if the condition or flood risk affects value. We aim to keep the process steady so executors can move on with the estate.
The nil-rate band is £325,000 per person and the residence nil-rate band is £175,000 per person where the home passes to direct descendants. Those figures are frozen until April 2028, so the property value in a Horsham estate can make a material difference to the tax outcome. If spouses or civil partners have unused allowances, those can usually be transferred.
A free market appraisal can help with selling, but it is not the same as a probate valuation. HMRC may accept an estate agent's figure in some straightforward cases, yet a Red Book report carries much stronger evidential weight, especially for homes with issues such as damp, movement or listed building constraints around Market Square. Our valuers prepare the report specifically for probate.
They can, because buyers in Horsham will look closely at maintenance, insurance and future repair costs. A property in the town centre conservation area or near the River Arun, the River Adur or Boldings Brook may need more careful analysis than a modern house in RH12 4SE. Our valuation reflects how those factors affect open market value on the date of death.

Probate valuations in Horsham start from £250. That fee covers a visit from our RICS-qualified valuer, review of the relevant local comparables and a Red Book report that states the open market value at the date of death. For properties with more moving parts, such as a listed home in the town centre conservation area or a detached house with suspected clay-related movement, the work can take longer, but the process stays transparent from the outset.
Turnaround is typically 5-7 working days once the inspection is complete, and we keep executors updated if more evidence is needed. The report is written in a format that can sit alongside the probate papers, estate accounts and solicitor correspondence without needing rework. That matters in Horsham because older red brick homes, tile-hung properties and post-war houses can all need different levels of analysis. A carefully prepared report is usually cheaper than dealing with an HMRC query later.
homedata.co.uk records show the local average house price at £525,845, so a probate fee should be judged against the work involved rather than against the estate value itself. Whether the property is a flat at £252,536 or a detached house at £822,544, we keep the valuation grounded in evidence and the condition seen on the day. Families often need a calm, fixed approach at a difficult point. Our valuers provide that, with the documentation needed to move the estate forward.
