Different circumstances require different property valuations. For example, if you are trying to sell a family property in Chelsea then the valuation needed is not the same as if you are carrying out an estate valuation following the death of a relative. Unfortunately, most homeowners realise this only halfway through the process.
In the UK, there are two main types of property valuation. The first is the formal approach that most chartered surveyors use when determining a value. Please note that there are five in total, all of which are approved by RICS.
The second is the practical valuation that is linked to certain milestones in life such as mortgages, probate, separation, and taxation.
In this article we unpack both options because distinguishing between the two can avoid unnecessary expense and frustration.
The five RICS valuation methods
RICS acknowledges that there are five technical approaches to valuing a property. Each approach is appropriate for a certain property type or set of market circumstances.
Comparative method
This is the backbone of residential valuation. A surveyor researches recent sales of similar types of property within the area, then accounts for differences to come to a conclusion of value. When the local market is booming and the number of recent sales increases, the comparative method can be the most reliable.
However, this approach does have its shortcomings In quieter rural markets, or in the case of an unusual property, it may be necessary to choose an alternative method.
Investment method
Where a property derives value primarily from rental income, the investment method is usually the most appropriate valuation approach. The surveyor assesses either the current passing rent or anticipated market rent, deducts relevant outgoings and applies a capitalisation rate to establish the property’s capital value. This method is used for buy-to-let investments, HMOs and mixed use assets.
The investment method links the value of the building directly to its income-producing capability, reflecting the way investors assess performance and long-term return potential.
Residual method
The residual method is mostly used where a property’s value sits in its development potential as opposed to its existing use. Examples include land with planning permission, derelict buildings suitable to redevelopment and large plots with the potential for accommodation.
With this approach, the surveyor will estimate the gross development value also known as the GDV, of the completed scheme. They will then deduct all anticipated costs including
construction costs, fees, finance, and developer's profit. The figure that remains will present the current value of the site.
This method is widely used by property developers, and most homeowners will only come across it if they are selling land or a property with significant development potential.
Profits method
Certain properties are inseparable from the enterprise within them. For example, a hotel, a care home, or a pub's worth lies in the income they generate. Under the profits method, the surveyor assesses the level of maintainable income that an efficient operator could generate from the property. They then convert this into capital value. The focus is on its ability to support a sustainable business operation.
This method is rarely used for standard residential property, but if you own a property that has strong operation or commercial abilities, this may be an option.
Cost method (contractor's method)
Where there is insufficient market evidence to support the valuation through comparable sales or income analysis, the cost method is used. This is usually the case for specialist or rarely traded assets such as heritage sites, schools, churches or other unique property types.
With this approach, the surveyor estimates the cost of constructing an equivalent building at current rates and then adjusts this figure to reflect factors such as age, depreciation and functional obsolescence.
Surveyors sometimes refer to this as "the method of last resort," and with good reason. The figures produced do not reflect what the market would pay, only what reconstruction would cost. For truly one-of-a-kind properties, however, this is often the only valid starting point.
Practical types of property valuation for homeowners
The five methods above are valuation approaches that surveyors use to calculate value. The types of valuations below highlight practical situations that homeowners are likely to encounter.
Whether you are preparing to sell, remortgage, settle an estate or make a long term financial decision, the purpose of the valuation determines the process and level of detail involved:
Market valuation (estate agent appraisal)
This is the type of property valuation most homeowners will encounter first.
A market valuation, which is referred to as an estate agent appraisal, is designed to estimate the achievable sale price of a property in current market conditions. An estate agent will assess the property’s condition, size, location and recent comparable sales before recommending an asking price strategy.

A market appraisal is usually complimentary and has no obligation attached. This is your first step if you are considering selling.
Mortgage valuation
When you apply for a mortgage, the lender will arrange a mortgage valuation before confirming the loan amount. The purpose of a mortgage valuation is narrow and is to assess whether the property provides security for the proposed lending. With this in mind, the valuation focuses on the lender’s risk position and offers an indication of market value for lending rather than a detailed assessment of the condition.
A mortgage valuation is not a survey. It will not flag structural cracks, damp in the cellar, or a roof in need of replacement within three years. If you are the purchaser, take out your own HomeBuyer Report or Building Survey. The mortgage valuation protects the bank while the survey protects you.
RICS Red Book valuation
A RICS Red Book valuation is a formal property valuation that is prepared in accordance with the RICS valuation - Global Standards, commonly referred to as the Red Book. In order to produce the Red Book valuation, the valuer needs to meet RICS requirements that relate to methodology, independence, professional standards and reporting. Due to this framework, Red Book valuations are relied upon in legal, tax, financial and professional contexts.
Homeowners and property owners are likely to require a Red Book valuation for matters that include probate, divorce, disputes, tax reporting or corporate property matters.
Probate valuation
Following a death, the deceased's estate must be valued for inheritance tax purposes. A probate valuation determines the open market value of the property as at the date of death. Estates where the value falls within the nil rate band (currently £325,000) are exempt from inheritance tax; above that threshold, the rate is 40%.
Getting this wrong has serious repercussions. An undervaluation could trigger an HMRC investigation, while an overvaluation means the estate pays more inheritance tax than necessary. HMRC's own guidance recommends instructing a professional surveyor, and given the sums at stake, that advice is worth following.
Matrimonial valuation
Divorce and separation require a clear, agreed figure for any jointly owned property. Typically, both parties or their solicitors agree on a single, jointly instructed valuer who produces a report for the court. The valuation needs to withstand scrutiny from both sides, which is why courts expect RICS-accredited professionals.
This type of valuation also applies when unmarried cohabiting partners separate and need an independent basis for dividing their property assets.
Capital gains tax valuation
Sell a property which is not your main residence and there is a potential capital gains tax charge on any profit. A CGT valuation establishes the value of the property at the date of acquisition and at disposal, so the taxable gain can be accurately calculated. Second homes, former rental properties, inherited homes you have held as investments — all may require one.
Precision matters here. HMRC can, and does, challenge valuations it considers unreasonable. A valuation prepared by a professional with supporting evidence is your best defence.
Insurance (reinstatement) valuation
An insurance valuation answers a very specific question: if your property were completely destroyed tomorrow, how much would it cost to rebuild it to the same standard? The answer accounts for construction materials, labour, demolition, site clearance, and compliance with current building regulations. It often bears little resemblance to the market value — a Georgian townhouse in Belgravia might sell for millions, but the reinstatement cost reflects construction economics, not the property market.
Buildings insurance based on an inaccurate reinstatement figure could leave you significantly under-insured. Regular reassessment is sensible, particularly after major renovation work.
Online and automated valuations
Online valuation tools use algorithms, recent sales data, and property databases to give an instant estimate. They are free, fast, and useful for a rough idea of which way the market is heading. Where they fall short is the finer detail — they cannot account for a recently upgraded kitchen, a roof that is starting to look sorry, or that the neighbour's extension now blocks the afternoon light.
Use them as a starting point for a conversation rather than a figure to base decisions on.
How to choose the right type of valuation
Your circumstances point you in the right direction:
- Selling? Begin with a market appraisal from an experienced local estate agent. If you need an independent figure for legal or financial purposes, commission a Red Book valuation.
- Buying? Your lender handles the mortgage valuation. Budget for a separate survey to understand the property's true condition.
- Going through a divorce? A matrimonial valuation from a jointly instructed RICS surveyor is the standard route for court proceedings.
- Dealing with a bereavement? A professional probate valuation protects you from HMRC challenges and ensures inheritance tax is calculated correctly.
- Disposing of a non-primary residence? A CGT valuation gives you a defensible basis for your tax return.
- Reviewing your insurance? A reinstatement cost assessment ensures your cover reflects what rebuilding would actually cost.
One professional valuation can sometimes serve more than one purpose — your surveyor or estate agent can advise on what is needed for your specific situation.
Frequently asked questions
What are the five types of valuations?
The five methods accepted by RICS are comparative, investment, residual, profits, and cost (also termed the contractor's method). For residential property in the UK, the most common approach is the comparative method, which looks at sales of similar properties nearby and makes adjustments for differences.
What is the difference between a mortgage valuation and a survey?
A mortgage valuation is just a quick confirmation that the property is worth enough to secure the loan. A survey — a HomeBuyer Report or full Building Survey — is a comprehensive inspection of the property's structural condition. They have different functions, and one is no substitute for the other. No estate agent would think of purchasing a property without a proper survey being carried out.
How much does a property valuation cost?
A market appraisal by an estate agent is normally free of charge. Mortgage valuations are generally covered by the lender's arrangement fee or charged at £150 to £1,500, depending on the property value. RICS Red Book valuations for probate, matrimonial, or tax purposes are normally charged between £250 and £600, though fees can be higher for larger or more complex properties.
Do I need a valuation to sell my house?
There is no legal requirement for a formal valuation before selling. The majority of sellers obtain one or more free market appraisals from estate agents in order to decide on an asking price. A formal RICS valuation is only required if you need a figure for legal, tax, or financial purposes — or if you simply want a wholly independent view to compare against what an agent recommends.
