At Fallows, we specialise in providing RICS Red Book–compliant Capital Gains Tax (CGT) valuations for a wide range of property types. Whether you are selling, gifting, or restructuring property assets, our Chartered Surveyors deliver clear, evidence-based reports that are fully compliant with HMRC requirements.

With extensive experience across residential, rural, and portfolio valuations, we ensure that our clients receive accurate assessments of market value at the correct dates — minimising the risk of disputes and giving peace of mind.

Why You Need a CGT Valuation

Capital Gains Tax is charged on the profit (or “gain”) you make when selling or disposing of a property that has increased in value. Unlike regular estate agency appraisals, HMRC requires valuations prepared by a qualified RICS Chartered Surveyor that meet strict professional standards.

Our reports are:

  • HMRC-ready and evidence-backed
  • Prepared by RICS Registered Valuers
  • Delivered promptly (typically 5–10 working days)
  • Designed to provide clarity for solicitors, accountants, and executors

Principal Private Residence (PPR) Relief Valuations

Many homeowners benefit from Principal Private Residence Relief (PPR), which can exempt a property from CGT. However, complexities arise when: The property has been let during ownership; Occupancy has been split between multiple homes, or, if parent remains in the property after gifting it to children.

We regularly provide CGT valuations to support PPR claims, often alongside rental valuations where ongoing occupation must be formalised to avoid a “reservation of benefit” that could prejudice the relief.

Second Homes & Rental Properties

Selling or gifting a second home or a property held under a tenancy usually triggers a CGT liability. Our valuations account for: Local sales at the time of transfer; the impact of any tenancies; historic values (if required) and HMRC's reporting standards and valuation guidance.

We frequently work with landlords, second-home owners, and families transferring property between generations.

Farmland & Agricultural CGT Valuations

Agricultural land presents unique challenges in CGT reporting. We assess the impacts of tenancies (AHAs, FBTs etc), constraints (SSSIs, Listings, Flood Zones), land quality, access to irrigation, hope value and planning constraints to name a few.

Our valuations are based on inspection, evidence, and detailed local knowledge across Hampshire, West Sussex, Surrey, Kent, Dorset, and Oxfordshire.

Portfolio Valuations

We frequently value large and complex portfolios, including buy-to-lets, HMOs, mixed use holdings and farmland.
We understand that portfolio owners require both clarity and efficiency. To minimise disruption, we can often inspect only a representative sample of properties while still preparing a robust portfolio-wide valuation. Reports are delivered alongside detailed spreadsheets, which owners find invaluable for both tax reporting and ongoing management.

Frequently Asked Questions About Capital Gains Tax Valuations

Find answers to the most common questions executors, solicitors, and families ask about probate valuations and the inheritance tax process.

What is a Capital Gains Tax valuation and when is it needed?

A Capital Gains Tax valuation is an assessment of a property’s market value to calculate tax owed when the asset is sold, transferred, or gifted. It’s often required when disposing of property, selling an inherited home, or transferring assets between connected parties.

What is a historical property valuation for Capital Gains Tax?

CGT is a tax calculated on how the price of an asset has increased since you came to own it. A historical property valuation determines the value of a property at a specific date in the past if there isn't clear evidence of a purchase price. The valuation is often the date of acquisition or a key tax reference date such as 31 March 1982 so that capital gains can be calculated accurately.

How far back can HMRC request a historical valuation?

HMRC can require historical valuations going back many years and as far as 1982 depending on the asset’s ownership history. This might include valuation dates decades in the past, especially for long-held family properties or agricultural land.

Can HMRC challenge my Capital Gains Tax valuation?

Yes, HMRC can and does challenge valuations. If there is a significant difference between your valuation and theirs, they may request further evidence or refer the case to the Valuation Office Agency. Using detailed, evidence-based reports reduces this risk.

What information is needed for a CGT or historical valuation?

A valuer will typically require the property address, photographs, floor plans, land area, planning history, and details of any significant improvements since the relevant valuation date. For historical dates, local market evidence from that time will be researched by the Valuer.

How are improvements accounted for in a CGT calculation?

The cost of qualifying capital improvements (such as extensions or conversions) can be deducted from the gain, so accurate records and receipts are important.

Can a CGT valuation reduce my tax bill?

Yes, if carried out accurately and supported by evidence, a valuation can ensure you only pay tax on the actual gain. Overstating the value at acquisition (or understating at disposal) could result in paying more than necessary.
