Question 1

How long does a water heater installation take in London?

Accepted Answer

A standard tank water heater installation in London typically takes two to four hours, assuming no major changes to existing plumbing or connections are needed.

Tankless installations or system conversions can take longer, particularly if venting, gas lines, or electrical panels require upgrading.

Question 2

How do I know if I need a new water heater or just a repair?

Accepted Answer

Minor issues such as a faulty thermostat, a worn heating element, or sediment buildup can often be resolved with a repair. However, if your unit is over 10 years old, leaking from the tank itself, or requiring frequent service calls, replacement is usually the more cost-effective path forward.

Question 3

Do I need a permit for water heater installation in London?

Accepted Answer

A permit is usually required for water heater installation in London, particularly when the work involves gas lines, electrical connections, or venting. It's worth confirming with your local building department before work begins.

You can find pros on HomeStars who are familiar with local code requirements and who can help ensure your installation is completed properly and up to standard.

Question 4

What size water heater do I need for my London home?

Accepted Answer

The right size depends on the number of people in your household and your daily hot water usage. As a general rule, a tank of 150 to 190 litres suits most households of two to four people, while larger households may need 270 litres or more.

Tankless units are sized by flow rate rather than tank capacity, so the right fit will depend on how many fixtures or appliances may be running at the same time.
