A qualified plumber handles everything from fixing a leaking tap to a full central heating installation. In Northern Ireland, plumbers must be Gas Safe registered by law to work on any gas appliances. Where the work calls for it, ask your plumber to confirm their Gas Safe registration and current public liability insurance, and check the Gas Safe register directly before any work begins or any money is paid.

Frequently asked questions
Do I need a plumber or a gas engineer?
If your job involves any gas appliances — boilers, gas cookers, gas fires — you need someone who is Gas Safe registered. Many plumbers are also Gas Safe registered and can handle both. If the job is purely water-based (leaks, taps, showers), any qualified plumber can help.
How long does a boiler installation take?
A straightforward boiler swap typically takes 1–2 days. If you are changing boiler type (e.g. from back boiler to combi) or relocating the boiler, it may take 2–3 days. Always get the work certified with a Gas Safe certificate on completion.
Should I supply my own materials?
Many plumbers prefer to source materials themselves as they have trade accounts and can guarantee the quality. However, if you already have a suite or fixtures you want fitted, a good plumber will work with them. Discuss this upfront and get it confirmed in writing.
What is power flushing and do I need it?
Power flushing cleans sludge and debris from your heating system using high-velocity water. It is typically recommended before a new boiler installation, or if some radiators are cold at the bottom while others are fully hot. It costs £300–£600 and extends the life of your boiler significantly.
Important
If your job involves gas — even a gas cooker connection — your plumber must be Gas Safe registered by law. Always ask to see their Gas Safe ID card before work starts.
