From new boiler installs to full central heating systems and unvented cylinders — KRL Plumbing & Heating gives South London homeowners a compliant, no-corner-cut install, backed by a written survey and clear pricing before any work starts.
Most homeowners don't realise what's been left out of a low quote — until something goes wrong months later.
Old sludge and debris get left in the system, clogging your brand-new boiler within months and voiding the warranty.
A bigger boiler needs a bigger gas supply. Skip this and the boiler can't perform — or worse, it's unsafe.
A rushed flue job is one of the most common causes of comebacks, leaks, and failed gas safety checks.
Every job below includes a full survey, written fixed price, and a compliance checklist — so you know exactly what you're paying for.
Combi, system or regular boiler swaps with correct flue, pipework and flush — fully certified.
From £2,000Low pressure to combi, or back boiler removal — done properly with pipe upsizing where needed.

Yes. When you book, a local engineer comes to your home, assesses your current setup and what you need, and gives you a written, fixed-price quote — with no obligation to go ahead.
We'll happily review it with you. Often a lower price means a power flush, pipe upsizing, or proper flue sealing has been left out. We'll show you exactly what's included on our side so you can compare fairly.
For no heating or hot water, we prioritise same-week appointments wherever possible across our South London coverage area.
