It is not a boundary, and no boundary is drawn. Where marks overlap, the one first in the key is drawn; the counts include every postcode.

Is HP8 at risk of flooding?

6 of the 220 postcodes in HP8 have a home or business in an area at risk of flooding from rivers or the sea, the Environment Agency says. At those, it puts 20 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 6 of 220 postcodes High: 20Low: 13

High: 3.3% or more a year (1 in 30). Medium: 1% to 3.3% a year. Low: 0.1% to 1% a year. Very low: under 0.1% a year (1 in 1,000). Each band is the chance of flooding in any one year.

Homes and businesses in an area at risk of flooding from rivers or the sea, as the Environment Agency counts them, added up over the postcodes. It is for the land, not each building, and leaves out surface water, groundwater and sewers. Each postcode page has its own figures and its flood warning areas.

What do homes sell for in HP8?

Homes in HP8 sold for a typical £745,000 in the 12 months to September 2026, across 71 sales, HM Land Registry's figures show. The 12 months before gave £767,500 from 108 sales: not a change larger than chance would explain, given which homes happened to sell.

£745,000 typical price, the 12 months to September 2026
£767,500 12 months to September 2025
  • Detached £1,025,000 43 sales
  • Semi-detached £623,500 16 sales
  • Terraced £500,000 9 sales
  • Flat or maisonette 3 sales, too few to price

Each bar is that kind's typical price, against the most expensive kind here.

Standard sales of homes at market value. A typical price is the median, the middle sale. Sales take weeks to be registered, so the last month or two are incomplete. Each postcode page gives the figure for its own postcode sector.
