The typical Marlborough home sells for about £317,500, and almost nothing actually sells at that price. Flats go for about £150,000. Detached houses go for over £600,000. Prices barely moved in a year. It is a town with two price lists and one misleading average.
In the Land Registry's twelve months to late May 2026, 92 homes sold at a median of about £317,500. Split by type, 24 flats went for around £153,000, 31 terraces for around £297,000, 17 semis for around £345,000 and 20 detached houses for around £606,000. Terraces sit closest to the headline figure, which makes them the nearest thing Marlborough has to a normal house. The detached market is a separate conversation, usually conducted by people who have already sold somewhere dearer.
The published house price index for the area rose about 1.6% in the twelve months to May 2026, which is a rounding error dressed up as a market. Flats went the other way, down about 1.8% over the same period. That is a small move, but it is the only type heading downhill, and a first-time buyer is allowed to notice. The index covers the wider area, not the town alone.
Band C is the most common council-tax band, and only about 22% of homes sit in bands A or B. A band D home pays about £2,570 a year. The valuation list takes the same view as the estate agents: modest is not the local default.
Renters only get a county figure. Typical private rent across the Wiltshire area was about £1,060 a month as of April 2026, up about 7% on a year earlier. That is a mean from the Office for National Statistics' rent index, not the middle of the listings. By size, it runs to about £730 for one bedroom, £950 for two, £1,190 for three and £1,710 for four or more. There is no published figure for studios or rooms. Landlords with a period front door in a protected market town are unlikely to treat the county average as a ceiling.
The Office for National Statistics models median household income here at about £58,900 before tax, for the financial year to March 2023. Put that beside a £317,500 median sale and a one-income household is looking at a stretch, not a purchase. Two decent salaries make the terrace market workable. The detached market was never pricing for salaries in the first place.
Across the sales that can be matched to an energy certificate's floor area, which is about 62% of them, the median price is about £4,240 per square metre. The typical floor area behind that figure is about 89 square metres. Those metres come without an off-street parking guarantee, and some come with listed-building paperwork. The price doesn't mention either.
The 2021 Census puts about 10% of homes at one bedroom, 28% at two, 34% at three and 28% at four or more. Three-bed family houses are the most common, and big houses are as plentiful as two-beds. One-bedroom homes are scarce, which goes a long way to explaining why the cheap end of this market is so short of choice.
Marlborough is priced above the middle but not beyond reach. It is fair value for a family on two incomes, and hard going for anyone arriving alone with one.
