A house in Aldenham costs around £900,000, if you can find one for sale. Hardly any change hands in a year. Band G is the usual council-tax band. Renting doesn't get you in cheaply either. Getting into Aldenham costs a lot, whichever way you go about it.
The Land Registry recorded three sales in Aldenham in the year to mid-January 2026, with a median of about £906,000. With so few sales, the register can't split that price by house type, so nobody can tell you from it what a semi fetches against a detached house. Three sales also means a single large house can pull the median up or down a long way. To get a sense of value, look up the Land Registry's sold prices for the specific street over several years. The last twelve months can't tell you much on their own.
The wider market moved only a little. The official house price index for the area covering Aldenham rose about 3% in the twelve months to May 2026, to an average of about £562,000, and flats rose by under 1%. Those are small rises. That average covers a much wider area than the village, and the gap between it and Aldenham's own sales shows how much more people pay to live here.
Council tax confirms the picture. Band G is the most common band, and only about 9% of homes are in bands A or B. A band D home pays about £2,406 a year, the figure most readers can compare with their current bill. A band H home pays about £4,812, and there are more of those here than in the two cheapest bands combined. Hertsmere's valuation list agrees that this is an expensive village.
Renting is cheaper only if you look at the whole borough. Across Hertsmere, the typical private rent was about £1,800 a month as of April 2026, up about 3% on a year earlier. That is the average from the Office for National Statistics' rent index for the borough, and Aldenham's own rents could be different. By size, the borough averages about £1,230 for a one-bed, £1,580 for a two-bed, £1,900 for a three-bed and £2,750 for four bedrooms or more. The index doesn't cover studios or single rooms. Homes to rent are scarce in the village anyway, because most households own their home.
Measured against local incomes, buying here is out of reach unless you already own a valuable home. Typical household income was about £75,000 a year before tax in the financial year to March 2023, a figure the Office for National Statistics models across a neighbourhood wider than the village. After tax it comes to about £55,000. A median sale of around £906,000 needs a lot of savings or equity on top of either figure. Most of these buyers are paying with the proceeds of the last house they sold.
The houses are mostly large. In the 2021 Census about 40% of homes had three bedrooms and 31% had four or more. About 26% had two bedrooms and only 3% had one. A small starter home for a single buyer is close to non-existent here, so the cheapest way in is a two-bed, and there aren't many of those.
Value is Aldenham's weakest point. Prices, council tax and even the borough's rents are high, and the sales record is too thin to show where a bargain might be.
