Is this reasonable?

However it doesn't apply in this situation any way.

i agree, if it was on his land then most likely yes, but from the situation described, imo, it doesnt apply

Really to what definition is ‘your home’ are you using?

There’s certain information you must give your customers when selling door to door (also known as doorstep selling).

This includes the sale of goods and services to customers at:

their home
their workplace
another individual’s home

You must also follow the general rules for accepting returns or giving refunds.

From the website above.

You can get away with emergency work, and anything under £75 I think is the figure. Otherwise a customer can demand all monies back for an infinite length of time. It falls under 'doorstep selling' legislation designed to trap rogue traders.
