Book Your First Clean99.7%
Bacterial Elimination Rate
Independent laboratory testing across 847 Chlorine-serviced pools in 2024 confirmed a 99.7% bacterial elimination rate — a figure that exceeds NHS recreational water standards by a factor of three. We use a precision-dosed chloramine reduction protocol developed with Imperial College London's water chemistry department. Your pool water is safer than most municipal supplies.

Minutes. Average service duration.
Thirty-eight minutes from gate to gate. Our technicians carry a full chemical analysis kit, a silent-operation vacuum rig, and a calibrated dosing system. Nothing is improvised on-site. Every visit follows a 24-point protocol that our senior chemist reviews quarterly. Fast because we have done this 4,200 times — not because we cut corners.

Basement pool, Mayfair townhouse — post-service

Call-out fee. Always.
Every quote is fixed. Every visit is fixed. There has never been a call-out surcharge, an emergency premium, or a "complexity fee" in the history of this company. Property managers tell us this is the single most unusual thing about us. We think it should be the industry norm. If your pool needs attention at 5 a.m. on a bank holiday, the price is the price.
Zero surcharges recorded across 6,200 service calls since 2017
Filtration system check, Kensington — standard visit
100%
Unmarked. Every visit.
Not one Chlorine vehicle carries external branding. Not one technician wears a branded uniform visible from the street. Our clients include three FTSE 100 executives, two members of the judiciary, and a number of individuals whose privacy requirements are non-negotiable. We designed our entire operation around discretion — because for our clients, a pool maintenance van parked outside is a statement they have not chosen to make.
Operational policy since founding — zero client complaints regarding discretion

"The water chemistry report sits in my procurement file. When our insurers asked for evidence of due diligence on pool maintenance, I sent them four years of Chlorine documentation. The conversation ended there."

"I manage fourteen properties across Mayfair and Belgravia. Chlorine is the only contractor I have never had to chase, re-brief, or apologise for to a client. That is not a compliment I give lightly."

zero incidents
"We had a water quality incident at a competitor-managed property that cost them a TripAdvisor rating and three bookings. Since switching to Chlorine two years ago, our pool has never once been flagged — and the written report after every visit is exactly what our insurers require."

"The discretion is what sold me initially. No van outside, no uniform at the front door, no conversation with the housekeeper beyond what is necessary. The pool is simply perfect every Monday morning."
