About this property

Letchworth Garden City:... Letchworth is the world's first Garden City that was founded by Ebenezer Howard in 1903, with a vision that would relieve the poverty and slum conditions suffered by so many within the late Victorian era. With a dream of Garden Cities where the best elements of town and country would be combined from the town in order to be used to benefit the ordinary townspeople. Now more than 100 years on, the Estate is now managed by the Heritage Foundation.

The agent hasn't said which band this home is in; you can look it up on GOV.UK. In North Hertfordshire, 2026/27 bills run from £1,632 a year in band A to £4,897 in band H.

Figures from MHCLG (Open Government Licence v3): the average bill for each band across North Hertfordshire, including the typical parish precept, so a parish's own bill can differ a little. Discounts lower the bill, such as 25% off for an adult living alone.
