Why apartments lose signal
New apartment blocks are well insulated, which keeps mobile signal out, and tenants notice straight away.
Tenant complaints
Poor signal is one of the first things tenants report.
Energy-efficient glazing
Modern windows block signal at the façade.
Concrete floors
Thick floors and cores stop signal between levels.
Car parks and amenities
Gyms, lounges and parking below ground often have no signal.
Outdoor signal, brought inside

Only legal boosters
Many boosters sold online are illegal in the UK and can disrupt the network for everyone nearby. We install only Ofcom-compliant, operator-approved systems.
Mobile signal before and after our installations
We survey every building before and after installation with our own survey app. These are real readings from recent projects, including buildings like yours.

Average signal strength (RSRP) across each surveyed floor. Usable means better than −107 dBm, the level phones need for reliable calls over 4G.
Apartment signal boosters: common questions
Does it cover every network?
A multi-network system covers EE, O2, Vodafone and Three, so every tenant benefits whichever network they use.
Can you install in occupied buildings?
Yes. We work in common areas and plan access with your managing agent.
How long does installation take?
It depends on the size of the building. The quote includes an installation plan, and we work around your opening hours to keep disruption low.
Are signal boosters legal in the UK?
Yes, if they meet Ofcom’s rules. Since the Wireless Telegraphy (Mobile Repeater) (Exemption) Regulations 2018, approved single-network boosters can be used without a licence. Multi-network systems need the networks’ consent, which we arrange. Unapproved boosters bought online are illegal, and Ofcom can act against anyone using one.
Can one system cover every network?
Yes. A multi-network CEL-FI QUATRA system covers EE, O2, Vodafone and Three, so staff and visitors get signal whichever network they use.
