HIU engineer, London and Essex
Heat interface unit servicing, repairs and replacement in flats on communal and district heating.
What we do with heat interface units

If your flat is on communal or district heating there is no boiler in it and no gas. What sits in the cupboard is a heat interface unit, taking hot water from the building’s plant and using it to run your radiators and your taps.
Those units are what we do: servicing, repairs and replacement, for residents and for the agents who look after whole blocks.
We work on Danfoss, Ideal, Worcester, Caleffi, V-therm, Evinox, Inta and more.
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!
For landlords, letting agents and managing agents
Several flats in one visit, at a lower price per flat. It is how most of the blocks we look after do it.
HIU servicing, per property
| Single property | £130 |
|---|---|
| Up to 5 properties | £120 each |

Per property, done in the same visit. More than 10 units, ring and we will price it.
- 1Tell us how many
The block or the portfolio, how many units, and whether they are on the same riser. That is all we need to price it.
- 2We agree a day
One visit, done in sequence. You tell residents, or we can work to a schedule you set.
- 3The work
Strainers out and cleaned, exchangers checked, actuator and controls tested on both heating and hot water, flow temperature read against what the building is sending.
- 4One report at the end
What we found in each flat, in plain words, with anything worth watching flagged before it becomes a call-out.

Get in touch
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.
