Is Softwashing a Legitimate Business in the UK?

Mark Cave

Once you've kept your startup costs lean, there's a question that always comes next. Is softwashing actually a proper business here in the UK, or is it just hype that's doing the rounds on social media? It's a fair question, and today I'm going to answer it honestly.

Mark Cave

I'm Mark Cave, founder of SoftWash UK. I've spent years around this industry, and I'll give you the opportunity and the reality check together. If I only gave you the exciting half, I'd be doing you a disservice.

Mark Cave

Let's start with the weather, because it explains a lot. The UK has a damp maritime climate. We get regular rain and mild winters. For biological growth, that's close to perfect. Green algae, red algae, which is Trentepohlia, lichen, moss and black mould all thrive here. Buildings and surfaces don't get a break from it.

Mark Cave

Now add the way we've been building. Over the last two decades, UK homes and commercial buildings have moved heavily towards through coloured render. Silicone thin coat systems like K Rend, Weber and Parex, and monocouche too. They look great when they're new. But they're porous, and they attract algae.

Mark Cave

Here's the part that matters for you. You can't simply blast those finishes with a pressure washer. High pressure can gouge the surface, strip aggregate and cause the coating to fail. So you've got a huge number of surfaces that need cleaning, and the quick, cheap method is exactly the one that damages them. That gap is where professional softwashing sits.

Mark Cave

Now think about what the customer is really buying. Nobody wakes up wanting sodium hypochlorite. They want asset protection. They want kerb appeal, a safer surface to walk on, and to avoid a big bill. Repainting a rendered house often runs to £3,000 to £8,000 once you factor in scaffolding and specialist painters. A softwash is a fraction of that. When you explain it that way, the conversation changes from a cleaning price to a cost avoidance decision.

Mark Cave

Roofs follow the same logic. Moss and lichen on concrete and clay tiles can be dealt with using softwashing and biocide treatments, without the surface erosion, blown seals or water getting in that pressure washing can cause. Manual scraping, then low pressure biocide application, means you can treat a roof without walking all over fragile tiles.

Mark Cave

So where does the money come from? Domestic render restoration is the obvious one. High demand, quick turnaround, and a visible difference the customer can see from the road. Then roof de mossing with a DDAC biocide such as Soft Wash Pro 50. Then hard landscaping, things like Indian sandstone, limestone and block paving, where pressure washing leaves embedded lichen spores behind. And then commercial work: retail parks, industrial units, schools, often out of hours, with strict runoff and exclusion zone controls.

Mark Cave

But the real shift is recurring work. A one off clean pays the bills this week. An annual or twice yearly biocide maintenance spray gives you predictable income, and it helps keep your cash flow steady through autumn and winter, when many exterior cleaners go quiet.

Mark Cave

Now the reality check, because this is not easy money. Softwashing is not passive and it's not get rich quick. You need to understand how different surfaces react, how to work out dilutions, how dwell time changes with the weather, and how to control runoff.

Mark Cave

Plant and property protection is the number one cause of customer complaints. Unmanaged runoff into a border, a fishpond or a storm drain can create serious financial and reputational damage, and one bad job like that can undo a lot of good ones. This is exactly why knowledge has to come before products.

Mark Cave

On the competition side, there are really two markets. Anyone can buy a pressure washer and call themselves an exterior cleaner. That end of the market is crowded, it's price driven, and it produces a lot of property damage. Professional softwashing is a different tier, because chemical handling raises the bar. You're working with sodium hypochlorite, surfactants like Clever Wash and biocides, and that demands real understanding.

Mark Cave

The customers worth having know this. Facilities managers, commercial property managers, housing associations, schools and discerning homeowners actively avoid splash and dash operators. They'll ask for site specific RAMS, COSHH assessments, and proof of public liability insurance, including written cover for treatment risk. If you can hand that over calmly, you're already ahead of most of the people you're competing with.

Mark Cave

Is a licence needed? At the moment, no. There's no mandatory statutory licence to offer softwashing in the UK. But please don't hear that as no rules. You're still bound by COSHH, by environmental law on drainage and surface water pollution, and by your general workplace safety duties. No licence doesn't mean no responsibility.

Mark Cave

That brings me to pricing, and this is where I see people undersell themselves. Don't price softwashing like manual hourly labour. Price it on risk, access, chemical volume and the value of the asset you're protecting. A flat patio with easy water access is a very different job from a three storey rendered elevation above a conservatory and a planted border. If you quote both by the hour, you'll lose money on one of them.

Mark Cave

So, practical takeaways. One, learn the surfaces before you chase the jobs. Two, sell the outcome: protecting the asset and avoiding a repaint. Three, get your paperwork in place before a commercial client asks for it. Four, build a maintenance offer into every job, so your work doesn't stop when the van pulls away. And five, quote for risk and value, not just your time.

Mark Cave

A podcast like this is a good starting point. But if you're serious about offering softwashing professionally, the gap between knowing about it and doing it properly is where training comes in. The SoftWash UK CPD Certified Softwash Training Course is an online course you can work through at your own pace. It covers chemical selection, surface identification, equipment, safety, compliance and pricing, built from years of real world experience, so you can avoid the mistakes that cost people money.

Mark Cave

Completing it also lets you become an Approved Softwash Applicator, with a listing in the directory and a place in the National Association of Softwash community. That can help justify premium quotes, because customers can see that you've invested in standards. You'll find all of it at softwashing.uk, along with the Knowledge Centre, chemicals and equipment.

Mark Cave

So here's something to think about before the next episode. Look at the last three jobs you quoted. Did you price the time, or did you price the risk and the value of what you were protecting? If it was just time, that's your first thing to fix.

Take care, and speak to you again soon.
