Is an online valuation accurate in TW5 9?
We publish a transparent prediction-vs-outcome accuracy report at /accuracy-report — every Offrly valuation is paired against the eventual HM Land Registry sold price for the same property. The figures there are the only accuracy claim Offrly makes.
What does the Offrly valuation NOT include?
Offrly's estimate is built from comparable sales and listing photos. It does not factor in lease length, ground rent, service charge, cladding (EWS1) status, or specific structural / planning issues — those are buyer-side due diligence items. For mortgage, probate or insurance binding purposes, a RICS-qualified surveyor is required.

How these numbers are calculated
The numbers on this page are illustrative tables anchored on the TW5 9 sold median. The Offrly valuation form above gives the address-specific estimate that doesn't rely on these averages.
- Local context (sold median + transaction count). Median of every TW5 9 sale recorded in HM Land Registry Price Paid Data over the last 12 months. The HMLR sale-to-registration lag is typically 2 weeks to 2 months, so the most recent 1–2 months are incomplete and may revise upward.

Sample valuations by property type.
Formula:
HMLR sold median for the type × bedroom multiplier (target ÷ 3-bed baseline). Multipliers (1: 77%, 2: 87%, 3: 100%, 4: 112%, 5: 124%) imply per-step uplifts of 1→2 +13.0%, 2→3 +14.9%, 3→4 +12.0%, 4→5 +10.7%. The 2→3 and 3→4 steps sit inside Nationwide — What Adds Value bands (2→3 bed: terraced 13%, semi 14%, detached 17%; 3→4 bed: terraced 10%, semi 10%, detached 13%); the 1→2 and 4→5 steps are unsourced and taper conservatively. Supplementary context: ONS adhoc 14839 (simple-average UK prices by bedroom count). Caveat: the formula treats each property type's HMLR median as a 3-bed baseline. For types whose typical bed-count differs (detached homes are often 4-bed), this approximation can over- or under-count the bedroom premium. For an address-specific number that doesn't make this assumption, run the form above. -
Condition uplift table.
Formula:
HMLR sold median × condition factor. Bands used: Excellent +5–12%, Good baseline, Fair −5–10%, Poor −15–30%. The "Indicative value" column shows the midpoint of each band. There is no UK-standard published condition-adjustment table — these are illustrative ranges. The RICS Red Book sets out the principles surveyors follow but does not publish a specific percentage table; individual surveyors apply their own adjustment in context. -
Lease-length discount table.
Formula:
HMLR sold median × lease factor. The "Indicative value" column shows the midpoint of each band. Discounts steepen sharply below 80 years remaining — the "marriage value" threshold under the Leasehold Reform, Housing and Urban Development Act 1993. The 70-year ≈ 88% relativity figure is consistent with HomeOwners Alliance's short-lease guidance. The sub-60-year band is Offrly-illustrative — no specific public source pins that discount; the bucket extends the marriage-value pattern as leases get materially shorter. Note: the Leasehold and Freehold Reform Act 2024 abolishes marriage value but is still being phased into force, so today's market still reflects the pre-reform discount pattern.
