What it is
HIU repair in Brentwood and Romford
Most heat interface unit faults announce themselves: hot water that runs cold halfway through a shower, heating that will not come on while the hot water is fine, water under the cupboard, pressure that keeps dropping, or a code on the display.Which of those it is matters, because they point at different parts. Hot water but no heating is usually the actuator or the controls. Neither one is often the supply into the flat rather than the unit itself. A blocked strainer behaves like a dying unit and costs a fraction of one.The call-out is £140 and that is to find out what is actually wrong. The repair is priced once it is diagnosed, so you are told what it costs before anything is changed. A part swapped on a guess is a part you have paid for twice.We work on Danfoss, Ideal, Worcester, Caleffi, V-therm, Evinox, Inta and more. Get a free quoteHow we do it
- 1Tell us what it is doing
The make of the unit, what the display says, and which of heating or hot water is affected. A photograph on WhatsApp is usually enough.
- 2We come and test it
£140 to investigate. We check the supply into the flat as well as the unit, because one behaves like the other.
- 3You get the price before the work
What is wrong, what it takes to put right, and what that costs. You decide.
- 4We fix it and test it with you
Run up, checked on both heating and hot water, and left working.

What our customers say
Anthony is amazing! We haven’t had heating in 4 and a half months and have had 3 previous engineers visit to try and fix it. Big thank you to Anthony for fixing it so quickly on his visit.
Anthony our engineer was amazing! Sorted out issue quickly and efficiently. Very polite and friendly!! Was a pleasure meeting you mate.
The plumber was really good. He fixed the HIU that was leaking. Now it doesn’t leak anymore, and everything works perfectly. He did a great job!
Other work we do
HIU servicing
A heat interface unit that is never looked at loses hot water performance slowly enough that nobody notices until it is bad.
Read moreHIU replacement
If you live in a flat on communal heating, the unit in your cupboard is a heat interface unit, and replacing one is a different job from anything in a house.
Read moreRadiators
A radiator added, moved, swapped for a towel rail, or balanced so the back bedroom finally warms up.
Read moreLeaks
A leak you can see, a stain on a ceiling you cannot explain, or a meter that keeps turning with everything off.
Read moreDrainage
A sink that drains slowly, a gully that backs up in heavy rain, or waste pipework that has never run properly.
Read moreToilets
Fitted, swapped, or the one that has been running quietly into the pan since the spring.
Read moreSinks and taps
Taps that drip, taps that have seized, and basins and sinks swapped without wrecking the worktop.
Read moreCylinders
G3 unvented qualified. Cylinders installed and replaced, vented and unvented, and the small parts on them that fail quietly until there is no hot water.
Read moreHeating controls
Thermostats, programmers and smart heating, fitted and actually set up rather than left on the default.

Questions about this work
What is the £140 for?
Coming out and finding the fault properly, including testing the supply into the flat and not only the unit. The repair itself is quoted after that, once we know what it is.
My neighbours have hot water and I do not.
Then the supply into the building is fine and the fault is in your flat: the unit, the strainer, the valves or the controls. That is the useful thing to know before anyone comes out.
There is water under the unit.
Turn the isolation valves off if you can reach them and ring us. One of the reviews on this site is a leaking unit that was fixed and has not leaked since.
Do you work on gas boilers?
No. We are not Gas Safe registered. If the appliance burns gas you need a Gas Safe registered engineer.
How do we get started?
Call 07444 756220 and speak to Anthony, or send a message on WhatsApp to the same number. You can also email monganplumbingandheating@yahoo.com. Include the property postcode and a short description of what needs attention.
What if the heating or hot water has stopped?
Tell us what has changed and any fault code on the display, and have a look at what the pressure gauge reads. If there is water coming out of the unit, turn the water off at the stopcock and ring us. A photo of the display saves a lot of guessing.

Tell us what is happening and where the property is. A photo of the unit, the fault code or the leak answers more than a paragraph does.

Good HIU service, knows his staff well and very quick and the gentleman even helped fixed error code on ambiente heating system, which was not part…
