A typical home in London Colney sells for about £420,000. Flats go for about a quarter of a million. Semis and detached houses clear half a million. Most homes sit in council-tax band D. It is a village price with a commuter-belt surcharge built in.
The Land Registry recorded 81 sales in London Colney in the year to May 2026, at a median of about £420,000. Terraces were the busiest part of the market, with 33 sales at a median of about £450,000. The 29 flats sold for about £250,000, the 14 semis for about £528,000, and the five detached houses for about £545,000. A detached figure built on five sales is closer to a rumour than a price, and a semi that costs almost as much as a detached house tells you plenty about the semis.
Over the twelve months to May 2026, the published house price index for the wider area rose 3%. Flats rose about 1%. That is a market edging along. Nothing in it is overheating or falling apart.
Band D is the most common council-tax band, and only about 10% of homes are in bands A or B, so cheap bills are scarce. A band D bill in St Albans comes to about £2,420 a year. Before an offer goes in, look up the band for the specific house on the valuation list, because band D is the line the particulars most often leave out.
Renting means paying St Albans district rates: about £1,920 a month on average in April 2026, up 3% on a year earlier. That is a mean from the Office for National Statistics' rent index for the whole district, so it isn't a median of the flats currently advertised in the village. By size, the district average runs from about £1,260 for a one-bed and £1,620 for a two-bed to about £2,000 for a three-bed and £2,890 for four bedrooms or more. A three-bed to rent costs about the same each month as a three-bed buyer's mortgage might, which explains why so few people rent one for long.
Household income in London Colney is high, though so is the bar. The Office for National Statistics models it at about £67,430 a year before tax for the financial year to March 2023, averaged across the three middle-layer areas the village covers. That is three years old and gross, so the take-home number is smaller and the house prices have moved since. A median-priced house still asks a lot of a household on that income, even a comfortable one. Two salaries and a long mortgage is the usual way in.
Measured by floor space, homes sold for a median of about £5,400 per square metre. The typical home behind that figure has about 79 square metres. The figure covers the 90% of sales the energy certificate register could match to a floor area, so a handful of sales are missing from it. Seventy-nine square metres is a modest family house, and buyers pay for every one of them.
The 2021 Census shows a village built around the three-bed. About 44% of homes have three bedrooms, 25% have two, 19% have four or more, and only 12% have one. A first-time buyer hunting for a one-bed has very little to choose from. The family buying a three-bed will be up against every other family looking for the same house.
House prices in London Colney are middling. They aren't cheap, they aren't outrageous, and any bargains get bought by the village's own three-bed families before an outsider spots them.
