The Real Cost of Starting a Softwashing Business

Mark Cave

Picture a new contractor. They've watched a few videos and they're excited. So they spend somewhere between £8,000 and £15,000, sometimes more, on a custom van build, electric hose reels and a high end proportioner. Often it's on finance. And they haven't landed a single paying customer yet. That's the shiny rig trap, and it sinks people before they start.

I'm Mark Cave, founder of SoftWash UK. Last time we looked at how window cleaners and jet washers can spot render and roof work on their existing rounds. The obvious next question is: what does it actually cost to get going? So let's go through it properly, category by category, and you'll see it's a lot less than that van build.

Mark Cave

There are six areas where your money goes. Training, equipment, chemicals, insurance, compliance and PPE, and then marketing and working capital. Let's start with training, because I think it's the cheapest insurance you'll ever buy.

Mark Cave

The SoftWash UK Approved and Certified Softwash Applicator Training Course is £595, down from £700, and it's CPD accredited. Now, here's something a lot of people don't know. Exterior cleaning falls under Building Repair and Maintenance within the scope of CITB, the Construction Industry Training Board. Eligible employers registered with CITB can claim up to 70% grant funding towards approved training. So check your eligibility before you pay full price.

Why does training come first? Think about what a mistake costs. A render respray callback can run past £3,000. Scorched lead flashing. Dead mature shrubs in a customer's border. Limestone that's been dissolved by the wrong product. Any one of those wipes out the cost of the course many times over. Knowledge comes before products, every time.

Mark Cave

Now equipment. This is where people overspend, so let me give you two sensible levels.

Mark Cave

The entry level setup is roughly £300 to £800. That's a chemical resistant pump sprayer or manual batch containers, lances with Viton or Santoprene seals, chemical resistant PVC or polyurethane hose, proper measuring jugs, and the access poles you need. That's genuinely enough to start doing paid work.

Mark Cave

The semi professional level is £1,200 to £2,500. That might be a 12 volt chemical diaphragm pump on a trolley. Or an inline proportioning system, like our Clever Injector Dosatron system, which is around £1,153, mounted on a portable trolley or a basic van frame. It takes the guesswork out of mixing and saves time on every job.

Mark Cave

My rule of thumb is simple. Start lean, prove your cash flow, and then pay for the automated proportioner and the van rig out of cleaning profits. Not out of personal debt. A van build doesn't win customers. Good work does.

Mark Cave

Next, chemicals. Your initial budget is about £150 to £350. A sensible starter basket has fresh sodium hypochlorite at 14 to 15 percent, a bleach stable surfactant like Clever Wash, which we dose at 200 to 1, that's 5 millilitres per litre, and a residual biocide such as Soft Wash Pro 50, which is DDAC, for roofs and tarmac. Then specialist products as you need them, like K Rend Algae Cleaner Gel X Pro for render, and oxalic acid for rust and lead staining.

Mark Cave

And there's an inventory trap here. Sodium hypochlorite breaks down with heat and sunlight. If you stockpile drums in a warm garage or in the van, you're paying for product that's losing strength every week. Buy fresh batches that line up with booked jobs.

Mark Cave

Now to the one that catches people out. Insurance. Expect to pay around £400 to £900 a year, depending on your height allowances and turnover. But the price isn't the issue. The gap is.

Mark Cave

A standard window cleaning or pressure washing public liability policy will almost always exclude chemical application, pollution incidents, and what's called treatment risk. That's damage caused directly to the surface you're cleaning. So you could be insured on paper and still be uncovered the day a render job goes wrong. Tell your broker plainly that you're carrying out chemical softwashing, and get written confirmation of treatment risk cover. Don't rely on a phone call.

Mark Cave

Then paperwork and protection. A RAMS and site specific COSHH pack is about £25 for compliant templates. PPE is roughly £100 to £200. That's chemical gauntlets, a full face visor or goggles, respiratory protection as specified by your COSHH assessment, coveralls, chemical resistant safety boots, and an emergency eye wash and plant rinsing kit. This isn't optional extras. Commercial clients and facilities managers will often ask to see the documents before you set foot on site.

Mark Cave

Last category: marketing and working capital. Marketing is about £150 to £400. A properly set up Google Business Profile, local pages for render and roof cleaning, decent vehicle decals, and a portfolio of before and after photos. Simple, local, and it works.

Mark Cave

And please keep a cash buffer of £500 to £1,000. British weather will cancel jobs. Commercial clients may pay on 30 to 60 day terms. You'll need fuel, spare fittings and O rings. Running out of cash in month two is a far more common reason for failure than running out of equipment.

Mark Cave

So what does it all add up to? If you're an existing exterior cleaner who already has a van and a water supply, you're looking at roughly £1,000 to £2,200 all in. That covers training, a starter kit, chemicals, your insurance endorsement and PPE. Starting from scratch, excluding the commercial vehicle, it's about £2,500 to £5,000 for a fully compliant, professional setup, including that working capital buffer. Compare that with a £15,000 van build and you can see which one leaves you standing when the first quiet month arrives.

Podcasts like this are a good start, but if you're serious about offering softwashing professionally, the structured route is the SoftWash UK CPD Certified Softwash Training Course. It's online, so you learn at your own pace, and it goes much deeper into chemical selection, surfaces, safety, equipment and pricing. Complete it and you can become an Approved Softwash Applicator, get listed in the directory, and join the National Association of Softwash community. Head to softwashing.uk to see the course, check the CITB grant, and browse the equipment and chemicals.

Here's your action step before the next episode. Add up your own version of those six categories on paper, and ask your insurance broker one question: do I have written treatment risk cover? Thanks for listening, take care, and I'll speak to you again soon.
