Tewin & Digswell Property Market Report — September 2026
In Tewin, Burnham Green and Digswell, a single sale can move the average. That is not the same as the market moving.
Small numbers deserve careful reading
This is a thin, high value pocket of the county. Across Welwyn, Tewin, Burnham Green and Digswell together, just 87 sales completed over the past twelve months, at a blended average of £690,778. Digswell alone saw only 16 sales, and its 14.9 per cent fall in average price should be read as a small sample finding its own level, not as a verdict on the village. Where volumes are this low, one or two unusual transactions can swing a percentage a long way in either direction.
Fewer deals, not necessarily a weaker market
Welwyn saw the sharpest change of anywhere on our patch this year. Completed sales in Welwyn fell 36.6 per cent on the year, the largest volume drop across any area we cover, even as its average price rose 3.4 per cent and price per square foot rose 4.9 per cent. Tewin & Burnham Green told a steadier story, 22 sales at an average of £898,758, down 7.5 per cent, with price per square foot down 6.7 per cent. Fewer transactions is not the same signal as falling value, and in villages this small the two need to be read apart.
Why a clear guide price still matters most here
Scarcity does not set the price on its own. With so few comparable sales in any given month, buyers here rely even more heavily on a guide price that is demonstrably grounded in genuine local evidence, not a round number. Nationally, supply is running at a twelve year high and buyer enquiries remain 9 per cent below last year, which makes clarity at launch, not just patience, the deciding factor in villages where the next comparable sale may be months away.
What this means
For sellers in a market this thin, your home will very likely be the only recent comparable for its own next sale. A guide price built carefully on the handful of genuine local comparables available, set out through Putterills’ five step process, matters more here than almost anywhere else on our patch.
For buyers do not read a single reported sale as the market rate. Ask for the fuller local picture before you decide what a fair offer looks like.
Across Welwyn, Tewin, Burnham Green and Digswell
Three small, high value markets, each best read on its own terms.
Welwyn. 49 sales, averaging £618,761, up 3.4 per cent, though completed sales fell 36.6 per cent on the year, the sharpest volume drop on our patch.
Tewin & Burnham Green. 22 sales, averaging £898,758, down 7.5 per cent, a number worth treating as a rough steer rather than a precise reading given how few sales it rests on.
Digswell. 16 sales, averaging £625,357, down 14.9 per cent, the smallest sample on our patch this year, footnoted accordingly.
If you are considering a move in one of these villages, the useful first step is a conversation about the genuine local evidence, not the headline percentage.
