A shared ownership valuation is a specialised assessment required by mortgage lenders and housing associations when purchasing or remortgaging a shared ownership property. Unlike standard mortgage valuations, this type of valuation calculates the full market value of your property and determines the percentage equity you currently own. Our RICS registered valuers in Egham follow strict guidelines to ensure your valuation report satisfies all requirements set by your lender and the relevant housing association. We have experience working with all major housing associations operating in the Surrey region.
The valuation process involves a thorough inspection of your property, taking into account its size, condition, location, and comparable sales in the TW20 area. Our valuers consider local market data, including recent sales of similar properties in Egham and Englefield Green, to provide an accurate assessment. For properties in shared ownership schemes, we also calculate the fractional value of your equity share, which is essential for staircasing calculations when you wish to purchase additional shares in your property. This calculation ensures you pay the correct price based on current market value rather than your original purchase price.
Egham features a diverse housing stock, from Victorian and Edwardian properties in the Conservation Area to modern apartments and new builds like those at Grace House in Maxwell Mews. The town contains 26 listed buildings within the Egham Conservation Area, including properties on the High Street and the Church of Saint John the Baptist. These historical elements can significantly impact property values and must be carefully considered during the valuation process. Our valuers have extensive experience assessing properties across all these different styles and ages. We understand how conservation area restrictions and listed building status affect market value.
New developments in the TW20 area continue to add to the housing stock, with conversions like Virginia House on Station Road providing additional residential units. Properties in these modern developments may have different valuation considerations compared to traditional housing, including remaining lease length and service charge implications. Our valuers stay current with all new build activity in the area to ensure accurate assessments whether your property is a Victorian terrace or a contemporary apartment.

Our valuer researches recent comparable sales in the Egham area, considering local market trends, property type, and specific features of your home.

Egham's property market presents unique characteristics that our local valuers understand intimately. The area combines historic properties in conservation areas with modern developments, creating a diverse market that requires expert knowledge to navigate accurately. From Victorian terraces on the High Street to contemporary apartments near the station, we have the expertise to provide reliable valuations across all property types in TW20. Our valuers are familiar with how factors like proximity to Royal Holloway University and flood risk areas affect property values in the local market.
We pride ourselves on providing clear, comprehensive reports that explain exactly how we arrived at your property valuation. If you have questions about the report or need clarification on any aspect of your equity share calculation, our team is available to discuss this with you. We want you to feel confident understanding your position in the shared ownership scheme and the options available to you for the future.

If you are looking to purchase additional shares in your shared ownership property (staircasing), you will need a current market valuation to determine the price of the extra share. Most housing associations require the valuation to be no more than 3-6 months old, so timing your valuation correctly is essential. Our team can provide you with a valuation that meets all requirements for staircasing calculations. When staircase purchasing, you will typically pay a percentage of the current market value for each additional percentage share you wish to acquire.
Several local factors influence property valuations in the Egham area. The town benefits from its proximity to Royal Holloway University, which creates demand for both rental and purchase properties. This institution significantly impacts the local housing market, with student accommodation and buy-to-let properties playing a notable role in the area's property landscape. Properties near the university often command premium valuations due to consistent demand from students, academics, and young professionals.
The Egham Conservation Area, with its 26 listed buildings including the Church of Saint John the Baptist and various period properties on the High Street, adds character to the town centre but may impose restrictions on modifications. Properties in or near conservation areas often require additional consideration during the valuation process. The presence of listed buildings, including two Grade II* and 24 Grade II properties, can affect neighbouring property values both positively through street scene character and negatively through development restrictions. Our valuers understand how these heritage designations impact market value.
Flood risk is another important factor in the TW20 area. The Environment Agency has issued flood alerts for parts of Egham, particularly in areas near the River Thames and surrounding waterways including postcodes TW20 8LJ and TW20 8SS. Properties in designated flood risk zones may be affected by insurance requirements and mortgage conditions, which our valuers take into account when assessing market value. The long-term flood risk from rivers, surface water and groundwater should be reflected in your property valuation. We check specific flood risk data for your property address during the valuation process.
The recent market conditions in TW20 show a notable shift from the peak prices of 2022. Historical sold prices in the area over the last year were 12% down on the previous year and 16% down on the 2022 peak of £613,607. This context is crucial for shared ownership valuations, as understanding the trajectory of local prices helps ensure accurate assessments. Our valuers analyse these trends carefully to provide valuations that reflect current market conditions while remaining compliant with RICS standards. The decrease in transaction volume, down 42% from the previous year with only 177 sales, also indicates a more cautious market requiring careful comparable analysis.
A shared ownership valuation is a specialised RICS assessment that determines the full market value of your property and calculates your current equity share percentage. This valuation is required by mortgage lenders and housing associations when purchasing a shared ownership property, remortgaging, or staircasing to increase your equity share. The report must be conducted by a RICS registered valuer and comply with the RICS Valuation Global Standards (the Red Book). Unlike a standard mortgage valuation, this specifically calculates the fractional value of your share versus the housing association's remaining share in the property.
Shared ownership valuations in the TW20 area typically start from £199 including VAT for standard properties. The exact cost depends on factors such as property type, size, and location within Egham. For larger properties or those in conservation areas, prices may be higher due to the additional complexity of assessing period features and listed building considerations. We provide transparent pricing with no hidden fees, and you will always know the total cost before booking your appointment. The average cost across the UK is around £452, but we offer competitive local pricing for the Egham area.
The actual property inspection typically takes between 30 minutes and 2 hours depending on the size and complexity of your property. After the inspection, you will receive your formal RICS valuation report within 3-5 working days for our standard service. We also offer a premium priority service with 2-3 working day turnaround for an additional fee if you need your report urgently. For staircasing transactions, it is worth noting that most housing associations require the valuation to be no more than 3-6 months old, so plan your timing accordingly.
You will need to provide details of your shared ownership lease, including the percentage equity share you currently own, the name of your housing association, and any recent correspondence regarding your property. If you are staircasing, we will also need details of the additional share percentage you wish to purchase. Our team will guide you through the required documentation when you book your appointment. Having your lease documents to hand will help the valuer complete the assessment efficiently and accurately.
Yes, our shared ownership valuations are fully compliant with requirements from all major housing associations and can be used for staircasing calculations. The valuation report includes the full market value of your property, which housing associations use to calculate the cost of purchasing additional shares. Most housing associations require a valuation that is no more than 3-6 months old, so it is important to time your valuation appropriately. When staircasing, you will typically pay the current market value percentage for the additional share you wish to acquire, which may be higher than your original purchase price if property values have increased.
Your shared ownership valuation will reflect the current market conditions in TW20, which may be higher or lower than your original purchase price. Recent data shows that property prices in Egham have decreased by approximately 1.23% over the last 12 months and are 16% below the 2022 peak. Our valuers will provide an accurate current market value based on comparable sales and local market analysis, ensuring your equity share is calculated correctly. If values have decreased, you should be aware that your equity share percentage now represents a lower monetary value than when you purchased.
The equity share percentage is calculated by dividing the value of your share by the total property value. If you own a 25% share in a property valued at £400,000, your equity is worth £100,000. The housing association owns the remaining 75% (£300,000). For staircasing calculations, if you wish to increase from 25% to 50%, you would pay 25% of the current market value to the housing association. Our valuation report provides both the full market value and your calculated equity share in pounds Sterling.
Several Egham-specific factors can affect your valuation. Properties in the Egham Conservation Area (with 26 listed buildings) may have restrictions that impact value. Proximity to Royal Holloway University creates consistent demand but also affects rental values. Flood risk in certain TW20 postcodes near the River Thames may affect insurance and mortgageability. The recent market downturn, with prices 16% below the 2022 peak of £613,607, means current valuations are lower than they were two years ago. Our valuers consider all these local factors when assessing your property.
Understanding your equity position is crucial for shared ownership properties. Your equity share represents the percentage of the property that you own, while the housing association owns the remaining share. For example, if you own a 25% share in a property valued at £400,000, your equity is worth £100,000. When looking to staircase to a higher share, you will need to pay a percentage of the current market value for the additional percentage being purchased. This means staircase purchasing can become more expensive if property values have risen since your initial purchase.
The TW20 area offers various shared ownership opportunities, particularly for first-time buyers looking to get onto the property ladder in Surrey. With average property prices around £445,110, shared ownership provides an accessible route to homeownership in this well-connected area. Our valuers can help you understand your current position and provide the documentation needed for any future decisions regarding your shared ownership property. We explain exactly how your equity share is calculated and what this means for your financial planning.
If you are considering staircasing, it is worth obtaining a current valuation before committing to purchasing additional shares. This gives you clarity on the exact cost and allows you to plan your finances accordingly. Our team can provide guidance on the valuation process and what to expect. With properties in Egham ranging from terraced houses around £399,414 to detached properties at around £791,694, the cost of staircase purchasing varies significantly depending on your property type and current market value.
