Parking an issue out front?
Assuming a van with microbore I reckon £60 for the first clean and then if monthly £35, eot £40.
Parking could be an issue,double yellow on a one way street,and you have to drive 'round the houses'to the back,about 600 yds.
I reckon an hour for reg clean.
Put me price in for first and reg cleans,a bit high but im not to bothered,got to much to do as it is
