RICS Red Book valuations accepted by HMRC








Our RICS-qualified valuers carry out probate valuations across Southsea, from PO5 terraces to flats closer to the seafront. We provide HMRC-compliant reports that record the open market value at the date of death, which executors need for probate and inheritance tax work. The process is handled with care, because families often need clear answers at a difficult time. A formal valuation also gives solicitors and personal representatives a figure they can rely on when the estate paperwork starts to move.
Southsea's market does not sit still for long. homedata.co.uk puts the overall average asking price at £303,275 in May 2026, with flats at £175,667, 2-beds at £243,535 and detached homes at £630,000. The current average listing price is £322,502, while the PO5 1 postcode sector saw 3.1% growth in the last year, or -0.1% after inflation. Those differences matter when an estate includes a period terrace, a leasehold flat, or a larger family home.

Our valuers inspect the property, review its condition, and assess what it would have sold for on the open market at the date of death. That date matters. HMRC wants a market value figure, not a guess based on emotion, a relative's memory, or the price an estate agent might suggest for a sale. The result needs to stand up if the estate is reviewed later, so we set out the reasoning in a clear and defensible way.
The report is prepared to RICS Valuation - Global Standards, often called the Red Book. That standard gives executors a formal record that explains the evidence behind the figure, including comparable sales and any factors that affect value in Southsea. A probate valuation is different from a quick appraisal because it is built for tax and legal use, not just for marketing. In a place like PO5, where flats and terraces can sit in very different price bands, that distinction is important.
Our approach also helps when a property has been in the same family for many years. A dated interior, a leasehold flat, or a home with later alterations can all change the number HMRC expects to see. We take those details into account, then match them against local evidence from Southsea and the wider Portsmouth area. The aim is simple, a figure that is fair on the estate and properly supported.

Southsea's average asking price sits at £303,275 in May 2026, but that headline figure hides a wide spread of values. homedata.co.uk lists flats at £175,667, 1-beds at £149,195, 2-beds at £243,535, 3-beds at £325,911, 4-beds at £518,310 and 5-beds at £659,533. The majority of properties sold in Southsea over the last year were terraced homes, so a probate figure for a terrace cannot be treated like a flat or detached house. Our valuers read that mix carefully before setting the date-of-death value.
Southsea's current average listing price stands at £322,502, up 1.61% since six months ago, even though asking prices have changed by -2.6% in the past 6 months. The PO5 1 postcode sector recorded 3.1% house price growth in the last year, or -0.1% after inflation, which shows how quickly figures can shift even within one local patch. That is why a broad suburb-wide average is rarely enough for probate work. We look at the property itself, then weigh the evidence against the most relevant local comparables.
Home.co.uk records show 8 properties reached a sold status in the last 90 days in Southsea, which underlines how selective the local market can be. Demand in Portsmouth and Southsea comes from a mix of young professionals, families and remote workers, while lower mortgage rates are helping affordability. Those market conditions can influence comparables, but they do not change the legal test for probate. The question remains the same, what would the property have achieved on the open market at the date of death?
Executors usually need a probate valuation before the estate can be reported to HMRC and before the Grant of Probate can move forward. That is especially important where the estate may sit above the nil-rate band of £325,000, or where the home passes to direct descendants and the residence nil-rate band of £175,000 may also apply. Joint ownership, more than one property, or a sale that is already being discussed can all make an accurate figure essential. The valuation helps the estate stay aligned with the legal forms from the very start.
Our valuers often help when families are dealing with a Southsea property that has been held for decades, or when a flat has very little recent comparable evidence in the immediate street. The figure must reflect the date of death, not the date of instruction or the date the property later reaches the market. That difference matters for the IHT return, estate accounts and any later capital gains records. A clear, dated report helps everyone involved work from the same number.
Some estates need a valuation because the home will be sold, while others need it because the beneficiaries are keeping the property. Either way, the probate figure sits at the centre of the estate administration. If the number is too high, the estate may pay more tax than it should. If it is too low, HMRC may ask for evidence later, which is why a Red Book report is such a useful document to have in place early.

An executor, solicitor, or family member books the valuation and shares basic details about the Southsea property, ownership, and the date of death. We then confirm the next step and arrange access.
Our valuer visits the property, notes condition, layout, age, improvements, and anything that could affect the open market value. In Southsea, that might include lease length, flat conversion changes, or the state of a terrace that has been owned for many years.
We review relevant evidence from Southsea and the wider Portsmouth area, using the closest sales and listing information we can find. This is where local judgement matters, because a PO5 flat and a detached house rarely follow the same value pattern.
The valuation is written up in formal RICS format with the reasoning behind the figure. Executors receive a clear document they can use for probate, HMRC correspondence, and estate records.
We send the completed report once the evidence has been checked and the figure signed off. Straightforward instructions are often completed within 5-7 working days, though more complex estates can take longer.
The report can be used with the IHT forms and the probate application, giving the estate one consistent value from the start. If HMRC asks questions later, the report gives a clear audit trail.
IHT starts with the nil-rate band of £325,000 per person, frozen until April 2028. If the home passes to direct descendants, the residence nil-rate band of £175,000 per person can also apply, and unused allowance can often pass between married couples and civil partners. That means a Southsea home worth £303,275 may not trigger tax on its own, but the rest of the estate can still push the total above the threshold. The property figure is often the largest single number in the estate, so it needs to be right.
Southsea homes vary sharply in value. A flat at £175,667 sits in a very different position from a detached house at £630,000 or a 5-bed at £659,533, even before savings, personal items and investments are added. Our valuers record the open market value at the date of death, which is the figure HMRC needs for the IHT return and the figure later used in estate administration. That record also helps solicitors keep the estate accounts consistent if the property is sold later.
Executors have 12 months from death to submit the IHT return, although the work often starts long before that deadline. HMRC can challenge a valuation within 4 years, so a Red Book report gives a clear trail of evidence if questions are raised later. A careful valuation now can prevent awkward queries when the estate has already moved on. It also keeps the family from having to revisit the same figures repeatedly during a stressful period.
A probate sale usually starts with the valuation, not the asking price. In Southsea, homedata.co.uk places the current average listing price at £322,502, but asking prices have changed by -2.6% in the past 6 months, so the number on a listing is not the same as the value HMRC needs. If the estate sells later at a different price, that sale becomes part of the estate record and any later capital gains calculation. The date-of-death figure remains the tax benchmark for probate.
Home.co.uk records show 8 properties reached a sold status in the last 90 days in Southsea, which suggests the local market is active but measured. That matters for executors deciding whether to sell, transfer, or hold the property while probate is completed. Our team can also support the next stage with conveyancing, which keeps the legal side moving once the valuation is in place. A clean start at the valuation stage makes the rest of the process easier to manage.
Families often ask how the sale timeline affects the probate number. It does not change the valuation date, but it does affect the paperwork that follows. A fair probate figure can protect the estate if the sale completes above or below expectations. It also gives solicitors and beneficiaries a clear point of reference if questions come up later.

HMRC needs an open market value at the date of death so the estate can be reported correctly. Our RICS valuers provide that figure in a formal report, which is used for probate, inheritance tax, and estate accounts. In Southsea, where property values can vary from flats at £175,667 to detached homes at £630,000, a simple guess is rarely enough. A proper valuation helps executors avoid errors that can affect the estate later.
Our probate valuations in Southsea start from £250. That fee covers the inspection, comparable research, and a formal report prepared to RICS Valuation - Global Standards. More complex estates, leasehold issues, or multiple properties can require extra time, but straightforward instructions are usually quoted clearly from the outset. We keep the process transparent so executors know what is included.
HMRC accepts a well-supported RICS probate valuation because it is prepared to a formal standard and explains the evidence behind the figure. The key point is that the report must reflect the open market value at the date of death, not a marketing price or a rough estimate. If HMRC asks for supporting evidence later, the report provides a clear trail. That is exactly why executors often choose a Red Book valuation.
Straightforward probate valuations are typically completed in 5-7 working days once access has been arranged. Some Southsea estates take longer if there are multiple owners, leasehold issues, or a property that needs more detailed comparable research. We always aim to keep the process moving without cutting corners. Families usually want a firm figure quickly, but accuracy still comes first.
The nil-rate band is £325,000 per person, frozen until April 2028. If the home passes to direct descendants, the residence nil-rate band of £175,000 per person may also apply, and unused allowance can often pass between married couples and civil partners. The value of the Southsea property is only one part of the estate calculation, but it is often the largest part. That is why the date-of-death valuation matters so much.
An estate agent's appraisal is useful for deciding a sale price, but it is not the same as a probate valuation. HMRC needs a formal, evidence-based figure that records the open market value at the date of death. An agent may help with marketing later, while our valuers provide the legal and tax figure first. If the estate is likely to be reviewed, the Red Book report is the safer document to hold.
Joint ownership can change how much of the property belongs in the estate, so the legal position needs to be checked before the probate figure is finalised. Our valuers can still provide the market value of the whole Southsea property, then the solicitor can apply the correct ownership share. That is common where a home was owned as joint tenants or tenants in common. The valuation itself still needs to reflect the date of death.
Each property needs its own date-of-death value, even if they are in different parts of Southsea or elsewhere in Hampshire. A flat, a family home, and a rental property can all sit in different value bands, so one estimate will not cover the estate properly. We can help executors keep the figures separate and clearly recorded. That makes the IHT return and estate accounts much easier to complete.
Our probate valuations in Southsea start from £250. That fee covers the inspection, the comparable evidence review, and a formal report prepared to RICS Valuation - Global Standards. For many straightforward homes in PO5, the report is completed in 5-7 working days, although more involved estates can take longer if there are multiple titles or a complex ownership structure. The price reflects the amount of work needed to defend the figure, not just a quick opinion.
We do not stop at a rough number. Our valuers consider the property's condition, layout, type, lease position if relevant, and the local evidence from Southsea and the wider Portsmouth market. Once the analysis is finished, we set out the logic clearly so executors and solicitors can see how the figure was reached. If HMRC asks for the basis of the number, the report is written to stand up to scrutiny.
Families often find it helpful that one instruction can keep the paperwork aligned. The same figure can feed the probate application, the IHT return, and the estate accounts, which reduces the risk of contradictions later. If the property is going to be sold, the valuation also gives a clean starting point for negotiations and for any later capital gains records. For Southsea estates, that can save time at the exact point when the family needs it most.
