RICS-certified valuations across all 32 London boroughs, from £195
London's shared ownership market is among the most active in the UK, with thousands of buyers each year using the scheme to purchase a share of properties across the capital. Whether you are buying your initial share, staircasing to increase your ownership, or remortgaging, our RICS-registered valuers provide accurate, lender-compliant valuations that reflect London's complex and fast-moving property market.
With average house prices sitting at £551,000 across London as of December 2025 - and flats, which make up the majority of shared ownership stock, averaging £430,000 - getting the valuation right matters enormously. A difference of just a few percentage points in the assessed value can mean thousands of pounds when calculating your staircasing cost or your lender's loan-to-value requirement.
Our London valuers carry out shared ownership valuations from £195, with pricing based on the property's value and size. We cover all 32 boroughs and the City of London, and our surveyors understand the specific factors that shape values in each local market, from the Victorian terraces of Hackney to the new-build apartment developments of Nine Elms and the Royal Docks.

Shared ownership
A shared ownership valuation is a formal assessment of a property's open market value, carried out by a RICS-registered valuer. It establishes the full market value of the property, which is then used to calculate the cost of purchasing additional shares during staircasing or to satisfy a mortgage lender's requirements. Unlike a general estate agent appraisal, a RICS valuation carries legal weight and follows the Royal Institution of Chartered Surveyors' Red Book Global Standards.
Housing associations across London require a RICS Red Book valuation before they will process any staircasing application. Mortgage lenders require the same when you are purchasing your initial share or refinancing. Our valuers produce a formal report that meets all these requirements, drawing on comparable sales data from across London's borough markets and adjusting for the specific characteristics of your property - floor level, finish quality, service charges, and lease terms.
London accounts for a significant proportion of shared ownership stock in England, with providers such as Peabody New Homes, Guinness Homes, and Square Roots offering properties across the capital. The London housing market recorded 70,800 transactions in the 12 months to December 2025, with approximately 3.1% of those being new-build sales - many sold on a shared ownership basis through housing association schemes.
Price movements vary significantly across London's 32 boroughs. Flat prices fell 3.6% year-on-year by December 2025, which has direct implications for buyers looking to staircase: a lower market value means a lower cost per additional percentage point purchased. Semi-detached properties in outer boroughs rose 2.9% over the same period. Zoopla reported a 0.2% fall in average London prices in the 12 months to January 2026, while Rightmove's sold price data shows overall values sitting 8% below the previous year and 11% below the 2023 peak.
In a market showing correction across certain property types, a precise and up-to-date RICS valuation is particularly important. Housing associations may not have adjusted their internal databases to reflect recent price movements, and a current market valuation from our registered surveyors ensures you are staircasing at a price that reflects what comparable properties are actually selling for right now.

London Clay, which underlies much of north and central London, is among the most shrink-swell-prone soils in the country. Projections indicate over 40% of London homes could be affected by subsidence by 2030, rising to more than 50% by 2070. Our valuers assess subsidence risk and visible cracking during each inspection, as these issues can materially affect the market value of a shared ownership property and may require specialist investigations before a lender will proceed.
London's geology creates specific valuation challenges that our surveyors understand in detail. The city's underlying London Clay is heavily susceptible to shrinkage during dry spells and swelling during wet periods - a cycle that puts stress on older foundations. Victorian and Edwardian properties with shallow strip foundations are particularly vulnerable, and cracked walls, sloping floors, and sticking doors and windows are common signs of ongoing movement. When valuing a shared ownership property in these areas, our assessors consider the condition of the foundations, the presence of nearby trees, any tree removal history, and any reported subsidence claims on the property file.
Flood risk is the second major environmental factor in London valuations. Surface water flooding is identified as the city's primary flood risk, occurring when heavy rainfall overwhelms the Victorian drainage network. Approximately 15% of London lies within a tidal or fluvial floodplain, protected by the Thames Barrier and associated flood defences. Areas along the Thames and its tributaries, and parts of south London including Croydon, carry additional groundwater flooding risk. Properties in high-risk flood zones can see their market values affected, and housing association buyers approaching staircasing should factor flood risk into their long-term ownership calculations.
Mining history adds a further dimension in some London boroughs. Chalk and flint mines exist beneath parts of Greater London, and while rarely a direct concern for modern residential properties, their presence can prompt ground stability queries from some lenders. Our valuers identify any relevant ground condition issues and reflect them appropriately in the assessed market value, noting any recommended investigations in the body of the report.
Our RICS valuers carry out a personal inspection of your property, examining its condition, size, specification, and any factors that distinguish it from comparable homes in the area. For shared ownership properties in London, this includes reviewing the specifics of the lease, the service charge and ground rent structure, and any restrictions or obligations that affect the property's attractiveness on the open market. Floor level matters significantly for London flats - ground-floor and basement flats typically command lower values per square foot than upper floors, and our valuers apply appropriate adjustments.
Following the inspection, we research comparable sales within your immediate area - typically within a half-mile radius for flats in inner London boroughs, or a wider search zone in outer London where comparable stock is less densely transacted. We adjust our valuation for differences in floor area, specification, condition, lease length, and building quality. The resulting Red Book report states our opinion of open market value in pounds, signed by a RICS-registered valuer whose name and membership number are included on the face of the report.
We deliver your report within 3-5 working days of the inspection. Our valuations are accepted by all major UK mortgage lenders and all London housing associations including Peabody, L&Q, Notting Hill Genesis, Catalyst, Southern Housing, and Clarion. If your lender or housing association has a specific format requirement, we confirm this before the inspection to ensure the report meets their specifications.

Select a date and time from our available slots. We cover all 32 London boroughs and the City of London, and typically have inspection slots available within 3-5 working days of your booking.
Our RICS-registered valuer visits your home, examines its condition and characteristics, reviews the lease documentation, and takes any necessary measurements or photographs. The inspection typically takes 30-60 minutes depending on the size of the property.
Your formal RICS Red Book valuation report is delivered within 3-5 working days of the inspection. It states our opinion of open market value and is accepted by all UK lenders and all London housing associations.
Submit the report directly to your housing association for a staircasing application, or to your mortgage broker and lender to support your purchase or remortgage. The valuation is valid for 3 months from the inspection date.

Commission your RICS shared ownership valuation only once your housing association has confirmed it will process your staircasing application, as the report is valid for just 3 months from the inspection date. Commissioning too early risks the valuation expiring before your transaction completes. For a remortgage, your mortgage broker will confirm when the lender needs the report - this is typically once your application has been submitted and the lender issues a valuation instruction.
A shared ownership valuation in London costs between £195 and £850. The exact price depends on the property's market value and the number of bedrooms, as larger and higher-value properties require more detailed comparable research and typically take longer to inspect. Our online quote tool generates an instant fixed price based on your specific London property details. There are no hidden charges or VAT surprises - the price you see is the price you pay.
You need a RICS Red Book shared ownership valuation when you are staircasing - buying additional shares in your home from your housing association. You also need one when remortgaging your shared ownership property with a new lender, as most lenders require a current RICS valuation before they will offer a product. Some London housing associations, including Peabody and L&Q, also require a RICS valuation as part of the resale process when you sell your share back to the association or on the open market. In every case, a formal RICS report is required rather than a simple estate agent's opinion of value.
The physical inspection of your London property takes approximately 30 to 60 minutes. After the inspection, your RICS Red Book valuation report is delivered within 3 to 5 working days. From booking to receiving your completed report, the full process typically takes around 5 to 10 working days depending on diary availability in your borough. The valuation itself is valid for 3 months from the date of the inspection, within which time you must complete your staircasing or remortgage transaction.
Yes. All RICS Red Book valuations for shared ownership purposes require a personal inspection. Our valuer needs to see the property's condition, layout, specification, and finish to make an accurate assessment, and must identify any specific factors that affect value - including evidence of subsidence movement, damp, disrepair, or any alterations. Desktop or automated valuations (AVMs) are not accepted for formal shared ownership purposes by any housing association or mortgage lender. Some lenders do accept desktop valuations for very straightforward remortgages, but your mortgage broker will confirm whether this applies to your situation.
London Clay, which underlies large parts of the capital, is one of the most shrink-swell-prone soils in England. Over 40% of London homes are projected to be affected by subsidence by 2030. If our valuer identifies signs of movement during the inspection - such as diagonal cracking above door frames, stepped cracking in brickwork, or sloping floors - they will reflect this in the market value assessment and note any recommended specialist investigations. Significant subsidence can reduce a property's market value and may cause a lender to require a structural engineer's report before proceeding with a mortgage offer.
Yes, a single RICS Red Book valuation can typically be used for both staircasing and a remortgage if both transactions proceed within the same 3-month validity window. Confirm this approach with your housing association and mortgage lender before booking, as some lenders require valuations from their own approved panel of surveyors. If both transactions proceed simultaneously - as is common when buyers staircase to 100% and immediately remortgage - one report usually covers both purposes, which can save you the cost of commissioning two separate valuations.
Approximately 15% of London lies within a floodplain, and surface water flooding is the city's most prevalent flood risk due to the high proportion of impermeable surfaces and the age of the Victorian drainage network. Properties in flood risk areas can see reduced market values, and some lenders will not offer mortgages on properties in the highest-risk zones without flood insurance in place. Our valuers assess flood risk as part of the valuation process, noting any relevant Environment Agency flood zone designations and how comparable sales in affected areas reflect the risk premium in the market.
Our RICS valuers cover all 32 London boroughs and the City of London. We operate extensively in inner boroughs where shared ownership stock is most concentrated - Tower Hamlets, Southwark, Lambeth, Islington, Hackney, and Newham - and across outer boroughs including Croydon, Bromley, Hounslow, Barnet, Enfield, and Bexley. We also cover the major development zones at Nine Elms, Canary Wharf, the Royal Docks, and Stratford, where housing associations offer large volumes of new-build shared ownership homes from providers including Peabody, Guinness, and Square Roots.
