General maintenance prices
Generally, these garden services are charged for by the hour, and the price you pay will vary on the size of your garden and on the area you live in. London garden service prices will be a lot higher than elsewhere.
As an estimate, a 20 by 13-foot garden would cost on average £150 to maintain in an afternoon, say.
However, a 25 by 20-foot garden would cost around £200 and may take a whole day to maintain.
For a big garden, say 40 by 25 feet, the gardening services associated with maintaining it could be £300 and take a day or two to complete.
