A shared ownership valuation is a specialist assessment required when you want to purchase additional shares in your property (staircasing), remortgage your shared ownership home, or sell your share on the open market. Unlike standard mortgage valuations, this report determines the full market value of your property and the percentage equity you currently own. In the TW1 area, with average property values exceeding £790,000, getting an accurate valuation is essential for any financial decision regarding your shared ownership property. Our valuers understand the complexities of shared ownership leases and how housing association covenants affect marketability.
The local Twickenham market presents unique characteristics that affect shared ownership valuations. Properties in conservation areas such as Twickenham Green, St Margarets, and Twickenham Riverside may have additional restrictions that impact their market value. Our valuers understand how listed building status, conservation area constraints, and the proximity to the River Thames influence property values in this desirable borough of Richmond upon Thames. We also consider the impact of the 85 conservation areas within the borough, many of which fall within the TW1 postcode.
TW1 encompasses several distinct neighborhoods, each with its own property profile. St Margarets has seen strong growth with prices increasing by 20.5% in the last year, while the broader Twickenham area has experienced a 17% decline. These variations highlight the importance of using a local surveyor who understands micro-market conditions across different parts of the TW1 postcode. Our valuers know the difference between properties in TW1 1 (St Margarets) and TW1 3 (Twickenham), ensuring your valuation reflects your specific location.
We provide valuations for all common shared ownership scenarios in TW1, including staircasing assessments where you purchase additional shares, resale valuations when selling your share on the open market, remortgage valuations for changing your mortgage deal, and Help to Buy valuations for properties purchased through government schemes.

When valuing shared ownership properties in Twickenham, our surveyors consider multiple factors specific to the local market.

Our local surveyor will visit your TW1 property to conduct a thorough inspection measuring all rooms and noting the condition of the building, fixtures, and any alterations you've made. The inspection typically takes 30-60 minutes depending on property size. Our surveyor will examine both the interior and exterior, taking photographs for the report.
We research recent sales of comparable properties in your specific area of TW1, considering local market trends and the unique characteristics of your property. This includes analysing sales in your specific postcode sector, whether TW1 1 (St Margarets), TW1 2 (Twickenham Riverside), or TW1 3 (Twickenham town centre). We also research shared ownership sales data from housing associations operating in the area.
Your RICS-compliant valuation report will be delivered within 5-7 working days, ready for submission to your housing association or mortgage lender. The report includes the full market value of your property, your current equity percentage, and detailed comparable evidence to support the valuation.

The TW1 postcode area presents several specific factors that our valuers consider when assessing shared ownership properties. The borough of Richmond upon Thames has 85 conservation areas, many of which fall within TW1 including Twickenham Green, St Margarets, and Twickenham Riverside. Properties in these designated areas may have restrictions on alterations that affect their value, and our valuers understand how these constraints impact market value. We know which streets fall within conservation areas and how this affects both valuation and saleability.
Geological conditions in TW1 also play a significant role in property valuations. The area is built largely on London Clay, which presents a shrink-swell subsidence risk. During dry spells, clay soil contracts and can cause foundations to shift, leading to structural issues. Our surveyors inspect for signs of subsidence damage, which is particularly relevant for older Victorian and Edwardian properties in areas like St Margarets and Twickenham Green. Properties with documented subsidence history may have reduced market values or require specialist insurance, and our valuers understand how to factor this into assessments.
Flood risk is another consideration for properties near the River Thames. While TW1 benefits from flood defenses including the Thames Barrier, long-term flood risk remains a consideration for riverside properties. Our valuers assess flood risk as part of the standard valuation process, considering the proximity to the Thames and tributaries including the River Crane and Duke of Northumberland's River. We check the relevant flood zones and consider any flood history reported for the property.
The local economy also influences property values in TW1. Twickenham is home to the Rugby Football Union and Twickenham Stadium, a major employer and events venue that drives local spending. Twickenham Studios in St Margarets is one of Greater London's major film studios, contributing to the local economy. These factors, combined with excellent transport links via Twickenham Station and good local schools, make TW1 an attractive area for buyers, which our valuers reflect in their market assessments.
Properties in TW1, particularly older Victorian and Edwardian homes, can suffer from several common defects that affect their value. Subsidence due to London Clay is the most significant structural issue in the area. Signs include cracking around doors and windows, misaligned frames, sagging floors, and rippling wallpaper. Our surveyors carefully inspect for these indicators during every valuation, checking walls both internally and externally for diagonal cracks that may indicate foundation movement.
Water ingress is another common issue, particularly in the many flat developments across TW1. Problems with flat roofs, balcony leaks, and cavity wall insulation failures can lead to damp and structural damage. The newer developments at Richmond Lock and Twickenham Gateway may have different defect profiles related to modern construction methods. Our valuers assess all visible defects and factor them into the final valuation, noting any repairs that may be required.
Many properties in TW1 also have issues related to outdated electrical wiring, particularly Victorian and Edwardian terraced houses that may have had minimal updates since construction. While not always visible during a valuation inspection, our valuers will note any obvious electrical concerns. Additionally, windows in period properties are often single-glazed and may require upgrading, which can affect value.

Several shared ownership developments operate within the TW1 postcode, and our valuers have experience with properties from all major housing associations. Twickenham Gateway on London Road, close to Twickenham Station, offers 1, 2, and 3-bedroom apartments through the shared ownership scheme. This modern development represents the newer end of the TW1 housing stock and typically requires different valuation considerations compared to period properties. The development, delivered by Solum (a joint venture with Network Rail Property), includes Yeoman and Collett Villas at Bradshaw Close.
Richmond Lock, developed by Octagon Group on the banks of the River Thames, offers over 100 residences including apartments, penthouses, and family homes. While not exclusively shared ownership, some units in this development may be available through shared ownership schemes. Our valuers understand the premium associated with riverside locations in TW1 and how views of the Thames affect market values.
Other shared ownership properties in the area are spread across various developments from housing associations including L&Q, Clarion Housing, and Metropolitan Thames Valley Housing. The average market value for shared ownership properties in the TW1 area typically ranges from £270,000 to £280,000 for a 50% share, though exact figures depend on property size, location, and market conditions. Our valuers have access to comprehensive data on shared ownership sales in the area to ensure accurate valuations, including recent transactions at developments like those on Holly Road and Vanquish Close.
A shared ownership valuation includes a physical inspection of your property, research into recent comparable sales in your specific area of TW1, and a formal RICS report stating the full market value and your current equity percentage. The report meets all requirements for staircasing, remortgaging, or resale transactions. Our valuers will measure all rooms, photograph the property condition, and assess any alterations you've made since purchase. The report also includes details of comparable properties used to support the valuation figure, specifically selected from your local TW1 area.
Our shared ownership valuations in TW1 start from £199 including VAT. This is competitive with local market rates, which typically range from £199 to £349 depending on property type and complexity. The national average RICS valuation costs around £452, making our service particularly cost-effective for TW1 property owners. Larger properties or those in complex situations (such as properties with significant alterations or in multiple occupancy) may incur higher fees, but we'll always provide a clear quote before proceeding.
The physical inspection typically takes 30-60 minutes, during which our surveyor will measure your property and photograph its condition. We deliver your written valuation report within 5-7 working days of instruction. For urgent cases, such as imminent staircasing deadlines, we offer an expedited service where possible. We'll always communicate clearly about timing and let you know if there are any delays due to market activity or property complexity.
Yes, staircasing (purchasing additional shares in your shared ownership property) requires a current RICS valuation to determine the market value at the time of purchase. Your housing association will require this official report before proceeding with any staircase transaction. The valuation must be dated within a specified period (typically 3-12 months depending on your housing association), so it's important to time your valuation correctly. Our team understands the staircasing process and can advise on timing to ensure your valuation remains valid throughout your transaction.
Yes, we value all types of shared ownership properties including flats, terraced houses, semi-detached properties, and detached homes. Our experience across the TW1 postcode, from St Margarets to Twickenham Green and the riverside areas, ensures we understand the local market factors affecting each property type. We've valued properties in period conversions on Montpelier Row, modern apartments at Twickenham Gateway, and Victorian terraces throughout the area. Whatever your property type, our local expertise ensures an accurate assessment.
Our surveyor will identify any structural issues during the inspection, including subsidence common in properties built on London Clay. These issues will be noted in the valuation report and may affect the market value. We provide clear guidance on any significant defects discovered. If subsidence is identified, we may recommend a specialist structural survey before you proceed with staircasing or remortgaging, as lenders may require additional reports. Our valuers understand how TW1's clay soil affects properties and can advise on the local context.
We work with all major housing associations operating in the TW1 area, including Clarion Housing, L&Q, Metropolitan Thames Valley Housing, Notting Hill Genesis, and The Guinness Partnership. Our reports are accepted by all these associations for staircasing, resale, and remortgage purposes. We understand the specific requirements of each housing association and can ensure your valuation report meets their criteria. If you're unsure which association holds your lease, we can help identify them from your lease documentation.
Yes, remortgaging your shared ownership home requires a valuation to satisfy your mortgage lender, just like a standard mortgage application. Our RICS valuation report will be accepted by all major mortgage lenders for shared ownership properties. The valuation assesses the full market value, which determines how much equity you have in the property and what mortgage amount you can borrow. Many lenders in TW1 offer shared ownership mortgage products, and our report meets their requirements.
