Building maintenance guides

Plumbing, bathroom fittings, electrical safety, drainage, waterproofing, roofs and preventive maintenance — practical, sourced guides for flat owners, tenants and building committees.

Every guide is written from published government guidance, standards bodies and manufacturer manuals, and every source is listed beneath it. Each one says plainly which jobs are safe to do yourself and which need a qualified tradesperson or engineer.

How we write and check these guides →

This guide is general information. Have gas, structural and live electrical work done by a qualified, licensed professional. Your building’s rules and committee decisions take precedence over anything written here.
