Boiler repairs for a flat or apartment
1960s low-rise, 2000s conversions and modern developments across the urban areas of CM/EN. We do a steady stream of boiler repairs across flat or apartments in West Essex and East Herts. Repairs in flats are mostly about communal-flue diagnostics, low pressure faults on undersized systems, and getting parts through concierge — routine work for us.

Not a national chain — your local engineer, your local prices.
Flat or apartment-specific issues we see
- Shared/communal flues on 60s low-rise limit boiler choice
- Freeholder/managing agent permission needed for external flue changes
- Older flats often have gas pipe undersized for modern combis
- Kitchen wall thickness often too thin for standard flue depth
Our approach for flat or apartments
For flats we always check flue routing options at survey — sometimes the only viable install requires switching from combi to system boiler, or vice-versa. We handle the freeholder paperwork for you.

Frequently asked questions
Do we need the freeholder's permission?▾
For any external flue change, yes — most freeholders approve within 2 weeks. We provide the technical spec they need to sign off.
Can we use a room-sealed appliance?▾
Always — we don't install open-flue boilers in flats, they're a CO risk in confined spaces.
Managing agent needs to know — can you handle that?▾
Yes, we regularly liaise with London and Essex managing agents for access.
Room-sealed only?▾
Correct — we won't fit or work on open-flue appliances in flats. CO safety is non-negotiable.
