Which? Trusted Trader — independently vetted & approvedHeat Interface Unit specialists for Brentford's heat network homes — from the riverside developments to the Great West Road. No hot water? Low pressure? We're based in Brentford TW8, so help is minutes away.
Based at Westlink House, Brentford TW8 — same-day response across the heat network developments.
If you live in one of Brentford's newer apartment developments, chances are your heating and hot water come from a communal heat network rather than your own boiler. The Heat Interface Unit (HIU) is the boiler-sized box in your cupboard that transfers heat from the network into your home.
When an HIU fails you lose hot water or heating just like a boiler breakdown — but many general plumbers won't work on them. We diagnose and repair HIUs across Brentford's developments, service them annually, and replace units at the end of their life.
Fast, tidy work on all major HIU brands — including Danfoss, SAV, Evinox and Altecnic units.
No hot water, no heating, pressure loss, leaks or noisy operation — most faults diagnosed and fixed the same day.
Annual servicing keeps filters and heat exchangers clean, protects efficiency and lowers your heat network bills.
End-of-life unit? We supply and fit replacement HIUs with minimal disruption to your apartment.
Same-day HIU call-outs across TW8 and the surrounding developments.

Common causes include a blocked plate heat exchanger, a failed control valve or actuator, low network flow, or a faulty temperature sensor. We diagnose HIU faults quickly and complete most repairs the same day.
Manufacturers recommend an annual service. Regular servicing keeps filters and plate heat exchangers clean, maintains efficiency, reduces your heat bills and prevents breakdowns.
HIUs aren't gas appliances, but they need a heating engineer with genuine HIU and heat network experience. Silverdale is Gas Safe registered and works on all major HIU brands.
A well-maintained HIU typically lasts 10–15 years. If yours is losing pressure, noisy or struggling for hot water, it may need a repair, a deep service or replacement — we'll give you an honest recommendation.
