Yes if your dropped calls spread across more than six rooms, four or five floors, a deep basement, a function room or an annexe. The G1000 lifts coverage to 1000 m² versus 500 m², raises maximum gain to 80 dB (from 75 dB), improves the noise figure to ≤3 dB (from ≤4 dB), pushes output to 23 dBm (from 20 dBm), upgrades the outdoor antenna to a 10 dBi directional panel (upgradable to 12 dBi Yagi), and extends the coax to 20 m. If you live in a five-six-bed detached home, the G500 is enough. If your property has seven or more bedrooms, a deep basement, a loft room, or you run a large bar, hotel, restaurant or multi-floor office, the G1000 at £505.91 is the right size.

In most UK large pubs, restaurants and small hotels (around 300–400 m² built footprint across two or three floors) the answer is yes, especially if the indoor panel sits on a central corridor and the outdoor panel points at the nearest O2 / Vodafone mast. 1000 m² / 10,764 ft² is the rated maximum. The 80 dB gain plus the 10 dBi outdoor panel are specifically tuned to deliver 2–3 bars into basements, cellars and upper floors. In weak rural fringe-signal areas coverage can drop — check Band 8 field mode on your phone before ordering. It will not cover a multi-building hotel estate or a warehouse; for that you need the C-series commercial range.

Because 1000 m² commercial spaces need the maximum possible captured donor signal from outside. The 10 dBi outdoor panel has a narrower beam and higher gain than an 8 dBi unit, so it pulls in weaker distant O2 / Vodafone mast signals and rejects noise from other directions. For very deep rural locations where the donor signal is barely one bar, the G1000 outdoor panel can be upgraded to a 12 dBi Yagi for even more capture. The trade-off is that the outdoor panel must be aimed precisely at the mast — a few degrees off and you lose gain.

For a typical three-to-four-storey townhouse hotel or small inn, yes — the 80 dB gain, 23 dBm output and 20 m coax are tuned to push Band 8 voice signal across four floors and into a standard basement. Mount the outdoor panel on the roof or top-floor fascia facing the nearest O2 / Vodafone mast, run the 20 m coax down through the stairwell, and aim the indoor panel from the central landing towards the reception and bar. If your basement is very deep (two levels below ground) or your building is five storeys or more, you may need to add a second indoor panel via the optional splitter kit — this is the G1000's expandable design for exactly that scenario.

It depends on your layout, your outdoor signal and whether you run a business from the property. If your five-six-bed house is open-plan, on two floors, and you already get two bars of O2 / Vodafone calls in most rooms, the smaller G500 is likely enough. The G1000 becomes the right choice when: (1) you have seven or more bedrooms, a deep basement, an annexe or a multi-storey extension that keeps dropping calls; (2) you are deep rural with only 1 bar of outdoor Band 8; (3) you run a large bar, restaurant, hotel, clinic or four-five-floor office; or (4) you need the cleanest possible voice quality at ≤3 dB noise figure for client or medical calls. The 365-day refund lets you trial it in situ.

For domestic properties in England and Wales, a single wall-mounted outdoor antenna under certain size limits usually falls under permitted development. However, the G1000 is a 10 dBi panel on a bracket and the install involves drilling through an exterior wall. For commercial premises — pubs, hotels, restaurants, offices — you should always: (1) ask the freeholder, landlord or management company if you lease the building; (2) check planning rules if the building is listed or in a conservation area; (3) confirm with your local council if the premises is in an Area of Outstanding Natural Beauty. Many councils treat a single wall-mounted panel as permitted development, but we recommend a quick phone call to your local planning office before you drill on any commercial building.

The G1000 is tuned for exactly this marginal-but-present donor level: 80 dB gain plus the 10 dBi outdoor panel take a weak 1 bar and re-broadcast it as a strong indoor signal across up to 1000 m². In practice, expect the rooms nearest the indoor panel to hold four bars, the furthest bedroom, basement or top floor to hold two to three bars, and the edges of the premises to hold one to two bars. If you stand outside and your phone shows zero bars and runs emergency-only, no Ofcom-legal booster can manufacture signal from nothing. Check Band 8 field mode on your phone before ordering — and consider the optional 12 dBi Yagi upgrade if the donor point is very weak.

The G1000 is voice-and-SMS-only on Band 8 (900 MHz) at £505.91, while the C1000 is a multi-band 4G LTE data booster on Band 20 (800 MHz) — they are completely different product lines. If your only pain is missed calls and failing texts on O2 / Vodafone / giffgaff / Sky Mobile across a large home or commercial venue, the G1000 gives you the most powerful voice coverage Boost4U makes. If you also need to stream, video-call over mobile data, run booking tablets on 4G or connect CCTV over cellular, the C1000 4G data unit is the better choice. The G1000 will not speed up your mobile internet — it is purely for calls and SMS.

Budget 60–90 minutes for a competent DIYer on a typical residential or small commercial install, and expect to work from a ladder for the outdoor panel. You will need a cordless drill for the two wall brackets, a screwdriver, a wrench for the coax connectors and a ladder to reach the gable, chimney or fascia line. The G1000 is designed for self-install: mount the outdoor panel facing the mast, run the 20 m coax through a drilled wall, mount the indoor panel on a central wall aimed at the covered zone, and plug in the 240V mains adapter. AGC locks on within about 60 seconds. No engineer visit, no call-out fee, no Ofcom licence — but if you are not comfortable on a ladder, drilling an exterior wall on a commercial building, or running 20 m of coax through multiple floors, ask a local handyman or low-voltage engineer for a half-day of their time.

The G1000 draws up to 20 W from the 240V UK mains adapter — about the same as four LED downlights left on 24/7. At typical UK commercial electricity rates that works out at roughly £47 per year of continuous running, around £4 a month. It is higher than the smaller G voice units simply because the G1000 delivers more power, more gain and a 10 dBi panel across 1000 m². There is no subscription, no SIM contract, no monthly fee — once bought, the unit just sits on the wall and amplifies the O2 / Vodafone Band 8 signal you already pay for through your existing phone bill. The 365-day money-back guarantee means you can trial it for a full year before committing.
