I would check with your local council in the first instance because it's quite possible different areas have different rules. Even if someone replied to say it's fine in your area, you can't use that as an excuse if you are in the wrong.

Aside from that, there are other things to consider like pedestrians negotiating the hose and how will it affect other cars around you? There will be other things to consider so regardless of whether it's legal or not, take your surroundings into account.

 

I understand this and I would be careful with the other cars & pedestrians coming my way.
TBH, i have been searching in the council website and haven't found anything.

 

Probably the best way is to write to them as they can't put everything on their website. By writing to them and asking for a reply in writing you will have proof, assuming a positive reply, to show anybody who asks. Alternatively telephone them and explain in detail what you intend doing and then ask for confirmation in writing.

 

First and foremost public liability must be your priority. It could be the most expensive car wash in history if someone trips on a hazard or slips on water that freezes late in the day as a result.

 

What about deploying one like this?
I have seen it when people charge their cars.

Id Look into rinse-less washing and a battery powered unit for rinsing when needed

I use one of these for rinseless application, its also got enough grunt to help shift some bigger particles. I use it even after a full foam wash to spray the car down with DI water/rinseless mix to eliminate water/soap spotting

Its the only karcher equipment id recommend tbh.

 

I can't tell you if that is appropriate mate. I appreciate you want to wash your car and I can relate to that. Ultimately only you can calculate the risks involved. 👍

 

I know, and that's why I really appreciate your advice and help.

 

@macmark upstairs flat, opposite side of the road and my water source comes from my kitchen sink tap 😅

@Merovingio I’ve got a 100ft expanded hose, this is my 4th one from cars running over it in the space of 5 years and a 50m extension. Once you have everything outside then it’s just a case of setting everything up, filling up buckets and setting products aside. If I need to fill up my spray bottles and foam cannons I do all that before putting them all in the buckets before heading out. I like to keep clean microfibres in a separate bag and store them in the boot to keep them out the way when washing the car. A lot of the time people cross the road when I’m washing the car, but now and then people walk behind me if their walking their dog on the grass, if I’m rinsing I stop, say hi and let them walk by. Or if I see someone pushing a pram, I immediately stop and clear a path so there’s room for the pram and I’ll apologise for causing any obstructions for the pram cause they need to go over the hose and the power cable. I’m starting to do rinseless washing and it’s a lot more convenient for me. All I need is a bucket filled with the solution and rinseless sponge all filled up in the bathroom with the shower, a bottle of QD hooked onto the side of the bucket as well as my IK sprayer and a bag of clean MF looped through my arm.

 

An email has just come in from Clean and Shiny with something that might be right up your street (pun intended)
It's the EGO wash and go battery operated pressure washer that is fed from a bucket, container or beer barrel. It's eye watering as well, EGO HPW2000E Cordless Pressure Washer

 

One thing to bear in mind, the noise regulations state you cannot make loud noise outside of the hours 8am to 6pm Monday to Friday and 8am to 1pm Saturday. Pressure washer probably counts as loud.

 

In the main, those strict times are set for professionals doing construction etc. For DIY power tool use, it's more of a goodwill thing otherwise you couldn't use your pressure washer on a Sunday.

This is what I found as an example.

Recommended hours for goodwill:

Weekdays: 9am–7:30pm
Weekends: 10am–5pm
Bank Holidays: Avoid before noon

Rural areas often tolerate longer hours, while Londoners face quicker complaints.

 

I've been using a Worx Hydroshot portable pressure washer for 10 years now.
I often take it to London and do my car and my dad's car on the street outside his house with no driveway.
As the hose is short and no power cable.....no tripping hazard.
Nowhere near as powerful as a proper pressure washer but enough for a good prewash and rinsing. The advantage here is you can jet without ricocheting onto neighbouring cars.
