Flue gas analysis and combustion checks on every service, with readings recorded on your certificate.

Whether it is a single boiler above a salon or a plant room serving an entire building, our engineers service, diagnose and repair to manufacturer specification and current regulations, and we tell you honestly when a repair no longer makes economic sense.

Plant Rooms

Plant room maintenance, upgrades and refurbishment.

Plant room maintenance, upgrades and refurbishment. Commercial boilers and cascades, hot water generation, booster sets, auto pressurisation units, circulation pumps, expansion vessels, controls and associated pipework, all looked after under one contract. Plant room surveys and condition reports for buildings you have just taken on. Labelling, valve charts and asset registers so your plant room is documented, not a mystery behind a locked door.

A neglected plant room is where building failures start. We keep yours serviced, documented and compliant, and when plant reaches end of life we specify and install replacements with minimal disruption to the building above.

Taken on a building with an unknown plant room? Call 0207 101 4121 for a survey.

What Clients Say

We are ABC Estates the selling agents of a property in Barnet. The purchaser required a gas safety certificate before proceeding. Pleasant Plumbers were instructed, and Mohan, their engineer arrived on time (early in fact). He was extremely efficient, and courteous. We will now be recommending Pleasant Plumbers to our own clients.
