The full figures for William Street
Domovita is a UK property portal. Sold prices here come from HM Land Registry and are free to search - no account, no sign-up.
Every standard-market sale HM Land Registry has recorded on William Street in the SL1 postcode district. Sales data to September 2026 (HM Land Registry), updated monthly. England and Wales coverage.
Across the wider SL1 district (not just this street), the typical (median) sold price is ↑ 588% between 1995 and 2025, median-on-medianCalculated across the wider SL1 postcode district, not this street alone (one street rarely has enough sales each year for a reliable trend). We compare the district's median sold price in its earliest year with at least 10 recorded sales against its most recent complete such year - a median-on-median comparison. We count only years that have had time to settle: never the current calendar year, and not the year before it until our data reaches March, because registrations are still arriving.
↑ 5% over the 2 years to 2025
Note: the mix of homes sold changes over time, which also moves this comparison - see the by-type breakdown.

Property types in SL1
Each share is that property type's slice of all standard (HM Land Registry category-A) sales in SL1. The price beside it is the mean sale price for that type across all recorded years. The freehold/leasehold split and any new-build figure compare averages weighted by number of sales. Much of a "flat vs house" or leasehold gap is the property type itself, not a premium.Whole SL1 district - not filtered

59% freehold, 41% leasehold, across all recorded years. Comparing new-build and existing homes type by type (each type weighted by how many sales it has here), new builds sold for around 2% less, across all recorded years. New builds sell mostly in the years they were built, so part of that gap is when they sold, not only that they were new; the detail below compares within each type.
Tenure and new-build detail by type
| Type | Freehold | New-build vs existing |
|---|---|---|
| Detached | 99% | -40% for new build |
| Semi-detached | 95% | -21% for new build |
| Terraced | 96% | -1% for new build |
| Flat / Apartment | 1% | +50% for new build |
New-build vs existing compares mean prices within the same type, so it is partly mix-adjusted - but it is not a like-for-like index.

Homes that sold more than once on William StreetEvery address on William Street with two or more recorded standard (HM Land Registry category-A) sales, matched on the exact address so a sale can never be attributed to a neighbouring home. "Change" is the difference between consecutive sales of the same home. "Annualised" is the constant yearly rate that would grow the earlier price into the later one over the time between them (compound), and is only shown when the sales are at least two years apart (closer pairs show how long apart they were). These are historical facts about past sales - they are not an estimate of what any home is worth today.
A home selling twice is the cleanest price comparison the Land Registry data offers - the same bricks, years apart. One address here has sold more than once.
