 Trustindex verifies that the original source of the review is Google. I can’t speak more highly of James, Ethan and Ivor. They worked solidly for 2 whole days to completely transform our old driveway and patio which was full of weeds creeping through the bricks and stained over years of wear and tear. They then sanded between the bricks to try and prevent the return of the weeds. In addition to this they cleaned our solar panels, treated the roof, and cleaned the external walls of the house including a large stain on the front which I was worried wouldn’t come off. The house looks brand new and several friends and family have commented particularly on the transformation of the patio and paths all around the house. The amount of work they have done in just two days is very impressive. These guys are polite, friendly, professional and just all round lovely people. Thanks fellas - will be using you again in the future for sure and recommending you to others.

 Trustindex verifies that the original source of the review is Google. I can thoroughly recommend Cleaning Doctor. We received an excellent service from start to finish — reliable, professional and extremely thorough, with real attention to detail.

Everything was carried out exactly as promised and to a very high standard. They were also a genuine pleasure to deal with: friendly, courteous, straightforward and completely dependable.

It’s refreshing to find a company that combines excellent workmanship with genuinely good customer service. We wouldn’t hesitate to use Cleaning Doctor again and would thoroughly recommend them.

Five stars from us.

 Trustindex verifies that the original source of the review is Google. I can totally recommend this Company for gutter cleaning after some work they carried out for me .
The owner James was excellent in every way and deserves 6 stars if that was possible!  His friendly approach, excellent work and reasonable charge are so appreciated in this cynical age.
Many thanks James

Award-Winning Service

Real examples of our solar panel cleaning expertise.

Our Process

Safe, Effective, Chemical-Free

We use the industry-standard pure water method for optimal results.

1. Pure Water Technology

We purify water on-site to remove all minerals and impurities. This "hungry water" actively absorbs dirt and dries without leaving any spots or streaks.

De-ionized Water: Zero mineral deposits

Chemical Free: Eco-friendly

Spot-Free Dry: Maximum light absorption

2. Telescopic Soft Brush

We use long-reach carbon fibre poles with specially designed soft-bristle brushes. This allows us to scrub the panels gently to lift grime without scratching the surface.

Long Reach: Cleans safely from ground

Non-Abrasive: Protects panel coating

Bird Mess

Safely removed.

Debris

Leaves cleared.

My professional accreditations

Why Clean Solar Panels?

The benefits of professional solar panel maintenance.

Maximise Output

Dirty panels can lose up to 30% of their efficiency. Cleaning them ensures you get the maximum return on your investment.

Protect Warranty

Many solar panel manufacturers require regular cleaning as part of their warranty conditions to prevent damage.

Remove Bird Droppings

Bird mess creates "hot spots" on panels which can cause permanent damage to the cells if not removed promptly.

Pure Water System

We use de-ionized pure water which dries spot-free, unlike tap water which leaves mineral deposits that block light.

Safe Cleaning

We use telescopic poles and soft brushes to clean safely from the ground or gutter level, avoiding damage to your roof.

Rain Isn't Enough

Rainwater contains contaminants and pollutants. Rain doesn't clean effectively; in fact it can make the problem worse.

Price Promise

The price quoted includes all labour and equipment – no hidden extras.

Fully Insured

We carry full public liability insurance, giving you complete peace of mind while we work on your property.

Frequently Asked Questions

Common questions about our solar panel cleaning services.

Why can't I just use a hose pipe?

Tap water contains minerals (calcium and magnesium) that leave white spots on the glass when they dry. These deposits can shade the cells and reduce efficiency. Our pure water system leaves zero residue.

How often should they be cleaned?

We generally recommend cleaning them once every 6-12 months, ideally in Spring to prepare for the longer days. However, if you live near trees or a busy road, more frequent cleaning may be beneficial.

Will cleaning damage the panels?

No. We use soft-bristle brushes specifically designed for solar glass. We do not use high-pressure washers, which can damage seals, nor do we use harsh chemicals that could affect the coating.

Do you need to walk on the roof?

In most cases, no. We use long-reach telescopic poles to clean panels from the safety of the ground or a ladder level. If roof access is absolutely necessary, we use proper safety equipment.

Does rain clean solar panels?

Rain helps a little, but it doesn't remove stuck-on grime, pollen, or bird droppings. Think of your car windscreen; rain doesn't keep it perfectly clean. A professional scrub is needed to remove the film that blocks light.
