A typical home in Letchworth costs about £400,000, and the money mostly goes on the outside space. A flat goes for about £200,000. A terrace is about £350,000. A detached house is about £650,000. In the first garden city, the garden is the part you pay for.
The Land Registry recorded 282 sales in the year to mid-May 2026, at a median of £400,000. Broken down by type, the 67 detached houses sold for a median of about £650,000, the 61 semis about £515,000, the 104 terraces about £350,000 and the 50 flats about £200,000. Terraces made up the largest group of sales, so the town median leans towards them. Ebenezer Howard's Three Magnets diagram promised the best of town and country with the drawbacks removed, but the price of a garden never made it onto the diagram.
The house price index for the area stood at about £417,000 in May 2026, up about 4% on a year earlier and down about 1% on the month before. For flats alone, the index rose only about 1% over the same year. Overall that is modest growth, and the flat market has barely moved while the wider index went up.
Band C is the most common council-tax band in Letchworth, and about 27% of homes fall into bands A and B. North Hertfordshire Council charges about £2,450 a year for band D, the bill most people use for comparison. The range runs from about £1,630 for band A to about £4,900 for band H. If you are buying in the terraced streets, check the band on the council's register for that exact house. Two terraces that look the same can be in different bands, and the bill difference lasts as long as you own the house.
North Hertfordshire's private rents average about £1,420 a month on the Office for National Statistics' index as of April 2026, up about 5% on the year. That is a mean for the whole district, so it does not single out Letchworth. Across the same district, a one-bed averaged about £1,010, a two-bed about £1,270, a three-bed about £1,550 and a four-bed or larger about £2,210. Rents are rising faster than the price index, and landlords in the district will have spotted that before tenants did.
The Office for National Statistics models median gross household income across Letchworth at about £63,000 for the financial year to March 2023. Gross means before tax, and that figure is three years older than the sale prices it is being set against. Against a £400,000 median house, it is a stretch for a single-income household and workable for two earners buying a terrace. Detached houses are a different conversation.
Of the sales that could be matched to an energy certificate, about 93% of the total, the median price was about £4,870 per square metre. The typical floor area behind that figure is about 86 square metres. That is a family-sized house with no spare room to speak of, and the garden is what makes the price.
Three-bedroom homes make up about 45% of Letchworth's households in the 2021 census. Two-beds are about 22%, four-beds or larger about 20% and one-beds about 14%. Raymond Unwin and Barry Parker laid out a town for families, and a century later the three-bed is still the default.
Letchworth sits in the middle for price. It is not cheap and it does not overcharge, and most of what you pay goes on the garden.
