What do electric boiler installation and repair services include?
This service includes all the tasks needed to get your electric boiler working to provide hot water in your home, whether it’s a new installation or fixing an existing one. This can involve removing the old water heater to make way for the new installation. Â
Other tasks can include positioning the tank, installing pipes, connecting the expansion tank, connecting the temperature and pressure valve, and attaching the electrical connections and wiring. Your handyman can also repair damaged electric boilers. Â Â Â
Removing the old water heater
Some boiler electricians can remove an old water heater to make way for a new one. Your specialist begins by cutting off the power and shutting off the water at their mains. A bucket is used to catch any water stored in the boiler that will pour out of its pipes. They can then detach all the pipes and connections and transfer the old boiler tank to a storage area. Some electric boiler installers may offer to dispose of the old tank for you.Â
Positioning the new electric boiler
Your hired boiler specialist can determine and place the boiler tank in the most appropriate spot in your basement, and centre them on a raised platform for easier access and as a safety measure against flooding. If you don’t have a raised platform, some specialists can make one for you for an additional fee. Â
Fitting and installing pipes
Next, your specialist installs the pipes. They measure the pipes and cut them to the right widths and lengths. They can remove the burrs on the lip and inner portions of the pipes to ensure better flow. Each pipe installation is wrapped with plumber’s tape, soldered or installed in both methods when necessary, for additional safety and protection against leaks. Â
The appropriate components like compression nuts, rings and flexible hose are likewise installed; your specialist ensures that all these installations have a perfect seal and a tight fit. Â Â
Attaching the expansion tank, temperature and pressure valve
Your boiler installation specialist attaches the expansion tank to the cold-water supply line next to or above the electric heater. The pipes they install are cut to the right lengths, deburred and soldered as needed. Your specialist can match the pressure of the expansion tank with your water line’s pressure using a handheld air pump once the expansion tank is installed. They finish the installation and seal the tank and pipes with soldering if necessary.Â
Attaching electrical connections
With the power and water still off, your specialist attaches the electrical wiring of the boiler to your main circuit breaker. Once all installations are done, they turn the water and power on and test if the water in your spigots run hot. Â
Repairing a damaged electrical boilerÂ
If you need an electric boiler repair service, your specialist inspects the boiler with the power and water shut off. They check for leaks in pipes, joints and fittings, pressure imbalances or other issues and do the appropriate fixes.Â

The boiler is currently only providing lukewarm water for a few minutes before the water goes completely cold. This issue is ongoing and means there is no reliable hot water available at the property. Could someone please attend the property to inspect the boiler and carry out the necessary repairs so that it is producing hot water properly again? The quote is for labour, I will pay for materials separately.

Breville Dual Boiler BES920 – blocked brew solenoid / no water flow)

Haggerston, Greater London, E2

I have a Breville Dual Boiler BES920 (Australian model). Symptoms: – Steam wand works normally – Brew pump runs but espresso does not come out – Hot water tap only drips – Loud rattling noise when brewing This is a very common BES920 issue and is almost certainly a blocked brew solenoid valve or scale blockage. I’m looking for someone experienced with espresso machine repair to: – remove the top panel – clean the brew solenoid / brew outlet – reassemble and test No parts required unless damaged. Machine runs on 230V (AU model, UK power compatible).

Installation of Hive thermostat for combi-boiler
£150
Lea Bridge, Greater London
8th Dec 2025
Installation of a hard-wired Hive thermostat to replace a manual thermostat that was installed with my Worcester combo-boiler. The boiler is a Worcester Bosch 8000 system and only installed 18 months ago - so should be compatible with the Hive thermostat. I’ve bought a Hive bundle that include the hub to allow set up of the WiFi-enabled remote control. I’ve included pictures of the boiler system, current thermostat unit and Hive pack. Happy to provide any extra information required to quote:
Josh made the whole process of installing my Hive thermostat very easy. Good communication, friendly and got the job done efficiently. Would definitely recommend

Replace heating elements on a boiler
£200
Elephant And Castle, Greater London, SE1
27th Nov 2025
This boiler is not working as it should and I was recommended to replace the heating elements. So looking for someone to do this... It's not heating water well or fast enough, it costs me insane amount of money (like summertime around £100 goes to just have hot water in the morning for one shower session). Now it provides barely warm water after 3 hours of heating water. I don't know price for this work so please do let me know how much materials and labour will cost!
Highly recommend Egzon! He went above and beyond to fix our boiler, even cleaned the lime scale (which wasn't part of the deal), he did everything super quickly, came on time, and overall he's very nice person! Will definitely recommend him to our friends and will call him if anything.

Maida Vale, Greater London

We have a bathroom cabinet which has lights built in. It looks to be all wired in correctly. We’ve tried replacing the bulbs but it is still not working. Would also like a shaver power port installed if possible. We have also purchased a new heating system tado, but it requires power to the compartment the boiler is stored in. There is currently a cable running there so I believe they just needs to be a new socket added.
