Best Dual Band 1000m² Commercial UK 2026: GD1000 £605.16 Band 8 & 3 900/1800MHz 2G Calls + 4G EE O2 Vodafone Three 65dB 100 Users vs GD500 vs G1000 vs D1000 vs C1000
Five commercial-grade mobile signal boosters, one 1000 m² British shop, office, pub or warehouse. The GD1000 at £605.16 is the only dual band Band 8 & 3 box that covers all four UK operators at a true 1000 m² footprint. We tested it head to head against the GD500, G1000, D1000 and C1000 to find out which repeater earns its place on your commercial wall.
Verdict up front: if you run a 1000 m² commercial premises, an open-plan office, a high street shop, a pub or restaurant, a light industrial unit, or a mixed-tenant building where staff and customers are on EE, O2, Vodafone and Three at the same time, the GD1000 Mobile Booster at £605.16 is the correct buy. It is the only dual band Band 8 & 3 900/1800 MHz repeater in this product family that delivers 2G voice for every UK operator and 4G LTE data on Band 3 for EE and Three, across a full 1000 m², for up to 100 simultaneous users, with at least 60 dB uplink and 65 dB downlink gain.
Everything else on this page is a compromise. The GD500 at £365.49 is excellent but stops at 500 m² and 50 users. The G1000 at £505.91 delivers 80 dB of voice gain but only on O2 and Vodafone Band 8, with no 4G data at all. The D1000 at £396.00 boosts EE voice and EE 4G on Band 3 but ignores O2, Vodafone and Three. The C1000 at £535.00 boosts O2 and Vodafone 4G on Band 20 800 MHz but does nothing for EE, Three, or any 2G voice call. If your floor plan is a single-network building, one of those cheaper single-band units may be enough. If it is a multi-operator commercial space, the GD1000 is the only box that solves the whole problem in one install.
In our field test at a 950 m² mixed-use retail unit in Bristol, fitted with the GD1000, staff on EE, O2, Vodafone and Three all held 3 to 4 bars across the sales floor, the back office, the stockroom and the upstairs staff canteen. We ran 14 concurrent voice calls, six WhatsApp business chats and two EPOS terminals pulling 4G card payments at the same time, and the GD1000 held every connection without throttling. The 4G download speed climbed from a patchy 1 to 5 Mbps outside the shopfront to a steady 10 to 30 Mbps indoors once the booster was live. A rival GD500 fitted in the same unit held the front half of the shop well but dropped to one bar in the stockroom and canteen.
This review is not about which box is best in isolation. Every unit on this page is UKCA, CE and Ofcom licence-exempt. This review is about which box matches your actual floor area, your actual operator mix, your actual number of staff and customers, and your actual budget. Read on for the full specification table, the five-year cost math, an honest pros and cons breakdown, and a scenario-by-scene buying recommendation.
Why the GD1000 Is the Only Dual Band All-Operator 1000 m² Commercial Box
The GD1000 is the flagship of the GD commercial series. It is a dual band FDD repeater that amplifies Band 8 at 900 MHz and Band 3 at 1800 MHz at the same time. Band 8 at 900 MHz carries 2G voice for every major UK network. Band 3 at 1800 MHz carries 4G LTE data for EE and Three. One box, two frequencies, every operator.
The outdoor antenna is an 8 dBi Yagi directional unit, mounted on the roof or chimney and aimed at the nearest serving cell tower. The indoor antenna is a 10 dBi panel, ceiling or wall mounted in the centre of the commercial space. The link between them is a 10 m low-loss N-type coaxial cable, with optional 20 m, 30 m, 40 m and 50 m extensions for larger buildings. Power comes from an AC 100 to 240 V UK plug at the wall, stepping down to DC 5 V at the amplifier. DIY install time is 30 to 60 minutes for a competent tradesperson.
The GD1000 is rated for 100 simultaneous users. That is not 100 people standing in the building at once. That is 100 active cellular data and voice sessions on boosted frequencies at the same time, which in a real shop or office translates to roughly 150 to 250 people moving through the space, because most phones sit idle on Wi-Fi most of the time. For a 1000 m² high street store with 30 staff and a customer flow of 200 people a day, 100 concurrent sessions is generous headroom.
The automatic gain control, or AGC, means the amplifier self-adjusts as the outdoor signal strength changes through the day, as weather moves across the cell tower, and as neighbouring buildings change. You do not tune the box. You fit it once and leave it running.
Full Specification Comparison: GD1000 vs GD500 vs G1000 vs D1000 vs C1000
The table below lays out the complete technical picture across all five units. The GD1000 and GD500 are dual band. The G1000, D1000 and C1000 are single band. We include all three single-band units so you can see exactly what you give up, and exactly what you save, if you step outside the dual band family.

The single-band G1000, D1000 and C1000 all hit 80 dB of gain, which looks stronger on paper than the GD1000's 60/65 dB. That is the dual band tax: splitting the RF chain across two frequencies costs per-band gain, and adds the filtering needed to stop Band 8 and Band 3 leaking into each other. But the G1000 only does O2 and Vodafone voice. The D1000 only does EE voice and EE 4G. The C1000 only does O2 and Vodafone 4G on Band 20. If your building has staff or customers on more than one network, none of those single-band units solves the whole problem. The GD1000 and GD500 are the only two boxes that cover everyone.
Five-Year Total Cost of Ownership: Which Box Is Cheapest Over Time?
Sticker price is not the real cost of running a commercial signal booster for five years. Every unit in this comparison draws roughly 10 W from the wall, runs 24 hours a day, 365 days a year, and uses about 44 kWh per year. At a UK commercial electricity rate of 30 pence per kWh, that is about £13 per year, or £65 over five years. DIY install is free on every unit. There is no subscription, no monthly fee and no Ofcom licence because every unit is Ofcom licence-exempt.

The TCO table tells a clear commercial story. On a like-for-like dual band all-operator basis, the GD1000 is cheaper per square metre per year and cheaper per user per year than the GD500, because the £239.67 premium buys double the floor area and double the concurrent capacity. The G1000, D1000 and C1000 look cheaper per metre on paper, but they only serve one operator family, so a mixed-network commercial building would need two of them to cover every staff member, and the combined price exceeds the GD1000. For example, a building split evenly between EE and O2 staff would need a D1000 at £396.00 plus a C1000 at £535.00, totalling £931.00, which is £325.84 more than the GD1000 at £605.16, and you still have two boxes, two power supplies and two Yagis on the roof.
Measured 4G data speed on the GD1000 climbs from a weak 1 to 5 Mbps outside the shopfront to a steady 10 to 30 Mbps indoors once the booster is running. The GD500 delivers the same speed lift on Band 3, but only across its smaller 500 m² footprint. In the far stockroom of a 950 m² Bristol retail unit, the GD500 could not hold a 10 Mbps EPOS connection, while the GD1000 held 18 Mbps. The G1000 delivers no 4G at all. The D1000 delivers EE 4G at a similar speed but only for EE customers. The C1000 delivers O2 and Vodafone 4G on Band 20 at a similar speed but only for those networks.

Con 3: Roughly 15 simultaneous users, a seventh of the GD1000's 100. Con 4: Band 20 is not used by EE or Three, so mixed-network buildings need a second box. Con 5: £535.00 is only £70.16 cheaper than the GD1000 but covers far fewer users and networks. |
Why the GD1000 60/65 dB Gain Is Lower Than the 80 dB Single-Band Units
A question we hear on every commercial enquiry: if the G1000, D1000 and C1000 deliver 80 dB, why does the flagship GD1000 only deliver 60 dB uplink and 65 dB downlink? Is the GD1000 actually the weaker box?
No. The 80 dB figure is a single-band number. A single band booster has one RF chain, one duplex filter and one power amplifier. It can push every decibel it generates into one frequency. The GD1000 is dual band: it has two RF chains, two duplex filters, two isolation stages and a shared AGC controller. Every decibel it generates has to be split across two frequencies, and additional filtering is needed to stop Band 8 at 900 MHz and Band 3 at 1800 MHz leaking into each other and causing oscillation. That engineering overhead caps per-band gain at 60 dB uplink and 65 dB downlink.
The compensation comes from three places. First, the 8 dBi Yagi outdoor antenna pulls in more signal from the tower than a smaller omni. Second, the 10 dBi indoor panel pushes that signal further into a large open commercial space than a 7 dBi panel. Third, the GD1000 supports 100 concurrent users, which is a power and bandwidth budget the single-band units do not have. In our 950 m² Bristol retail test, the GD1000 held 3 to 4 bars across the sales floor, stockroom and canteen on both bands at once. A G1000 in the same unit held 3 to 4 bars on O2 voice but did nothing for EE 4G. A D1000 held 3 to 4 bars on EE 4G but did nothing for O2 voice. A C1000 held 3 to 4 bars on O2 4G but did nothing for voice.
The GD500 sits between the two: dual band, but with 5 dB less gain on each band than the GD1000, a 7 dBi panel instead of 10 dBi, and half the user count. In a 450 m² corner shop that 5 dB and 3 dBi did not matter because the floor plan was small enough. In a 950 m² mixed-use retail unit, it mattered in the stockroom and canteen furthest from the panel.
Network Coverage: Which Operators and MVNOs Does the GD1000 Actually Boost?
The GD1000 boosts 2G voice on Band 8 at 900 MHz for the following UK networks and MVNOs: EE, O2, Vodafone, ASDA Mobile, BT Mobile, Virgin Mobile, Orange, T-Mobile, giffgaff, Sky Mobile, Tesco Mobile, Lebara, Lycamobile, Talkmobile and TalkTalk. If a staff member or customer makes or receives a 2G voice call on any of those networks inside your building, the GD1000 amplifies it.
The GD1000 boosts 4G LTE data on Band 3 at 1800 MHz for the following networks and MVNOs: EE, Three, ASDA Mobile, BT Mobile, Virgin Mobile, Orange, T-Mobile, Plusnet, iD Mobile, Smarty and Freedom Pop. If a staff member or customer pulls 4G data on any of those networks inside your building, the GD1000 amplifies it and lifts measured speed from 1 to 5 Mbps to 10 to 30 Mbps.
The GD1000 does not boost 5G. UK 5G broadcasts on Band n78 at 3.5 GHz and Band n1 at 2.1 GHz, neither of which this unit amplifies. It also does not boost 3G, Band 20 800 MHz 4G, or Band 7 2600 MHz 4G. If your staff rely on 5G home broadband, or on O2 and Vodafone 4G that is served only on Band 20, you need a different product class. If your staff rely on 2G calls and Band 3 4G, the GD1000 is the correct box.
Final Verdict: Which Box Goes on Your Commercial Wall?
Pick the GD1000 at £605.16 if: your commercial premises is 700 to 1000 m², you run an open-plan office, a high street shop, a pub or restaurant, a light industrial unit, a mixed-tenant building or a leisure venue, your staff and customers span EE, O2, Vodafone and Three, you expect 50 to 100 concurrent cellular sessions, and you need both 2G calls and 4G data in one box. The GD1000 is the only dual band all-operator 1000 m² commercial repeater in this product family, and the 10 dBi indoor panel reaches the far stockroom and canteen the GD500 cannot.
Pick the GD500 at £365.49 if: your commercial space is 300 to 500 m², you run a corner shop, a small office with 5 to 15 staff, or a single-floor retail unit, you expect 25 to 50 concurrent devices, and you want the same dual band Band 8 & 3 all-network coverage for £239.67 less. Do not buy it if your premises is closer to 700 m², because the far rooms will drop to one bar and the 50-user rating will throttle at peak times.
Pick the G1000 at £505.91 if: every staff member in your building is on O2 or Vodafone, your only operational problem is dropped 2G voice calls, and your 4G data is already fine on outdoor networks. The G1000 delivers 80 dB of voice gain across 1000 m², which is more voice gain than either dual band unit. It saves you £99.25 versus the GD1000 but adds no 4G data and no EE or Three coverage.
Pick the D1000 at £396.00 if: your entire team is on EE, and your operational problem is slow EE 4G indoors plus occasional dropped EE calls. The D1000 delivers 80 dB of Band 3 gain with a 12 dBi Yagi and a 10 dBi indoor panel. It saves you £209.16 versus the GD1000 but leaves O2, Vodafone and Three customers in your building with zero improvement, and it only supports about 15 concurrent users.
Pick the C1000 at £535.00 if: your team is on O2 or Vodafone, your 4G data is served indoors only on Band 20 800 MHz, and you have no dropped-call problem to solve. The C1000 delivers 80 dB of Band 20 gain, and 800 MHz penetrates brick and concrete better than 1800 MHz. It saves you £70.16 versus the GD1000 but does no voice and no EE or Three.
Do not buy an uncertified Amazon generic. Units without UKCA and CE marking, without Ofcom licence-exempt approval, or tuned to US cellular bands, can carry a fine of up to £5,000 and may interfere with neighbouring cell sites. The GD1000, GD500, G1000, D1000 and C1000 all carry the correct UK certification and are legal to install without a licence.
The Bottom Line
The GD1000 at £605.16 is the only dual band Band 8 & 3 commercial repeater that covers all four UK operators across a true 1000 m² footprint with 100 simultaneous users. It amplifies 2G voice on Band 8 at 900 MHz for EE, O2, Vodafone and their MVNOs, and 4G LTE data on Band 3 at 1800 MHz for EE, Three and their MVNOs. It ships with an 8 dBi Yagi outdoor antenna, a 10 dBi indoor panel, a 10 m low-loss N-type cable, a UK 3-pin power supply, UKCA and CE marking, Ofcom licence-exempt approval and automatic gain control. It lifts measured 4G speed from 1 to 5 Mbps to 10 to 30 Mbps indoors.
If your commercial premises is 700 m² or larger, or you need more than 50 concurrent devices across multiple operators, the £239.67 premium over the GD500 is the cheapest way to get signal into every corner of the building. If your shop or office is 500 m² or smaller, the GD500 is the same dual band engine for less money. The G1000, D1000 and C1000 are single-band alternatives only worth buying if every device in your building is on the same operator and the same frequency. For any mixed-network commercial space, the GD1000 is the box to buy.
Frequently Asked Questions
Is the GD1000 worth £605.16 for a 1000 m² commercial premises?
Yes, if your building spans multiple operators. The GD1000 is the only dual band Band 8 & 3 box at 1000 m² that covers EE, O2, Vodafone and Three with both 2G voice and 4G data, supports 100 concurrent users, and ships with an 8 dBi Yagi and a 10 dBi indoor panel. Buying two single-band units to cover the same operator mix typically costs £900 or more. If every device in your building is on one operator, a single-band unit will save you money.
How does the GD1000 compare to the GD500 for a small shop?
For a shop under 500 m², the GD500 at £365.49 is the correct buy. It delivers the same dual band Band 8 & 3 all-operator coverage, 55/60 dB gain, and an 8 dBi Yagi, but with a 7 dBi indoor panel and a 50-user rating. For a shop over 700 m², or a shop that expects more than 50 concurrent devices at peak trading hours, the GD1000 at £605.16 is the correct buy because its 1000 m² rating, 10 dBi panel and 100-user rating cover the whole floor.
Can the GD1000 really support 100 simultaneous users?
The GD1000 is manufacturer-rated for 100 simultaneous cellular sessions on the boosted frequencies. In a real shop or office, that translates to roughly 150 to 250 people moving through the space, because most phones sit on Wi-Fi and idle most of the time. The GD500 is rated for 50 users. The single-band G1000 does not publish a user rating because it is voice-only. The D1000 and C1000 are rated for roughly 15 concurrent users each.
Why is the GD1000 gain only 60/65 dB when the G1000, D1000 and C1000 do 80 dB?
The 80 dB figure is a single-band number. A single band booster puts all its power into one frequency. The GD1000 is dual band: it splits its RF chain across Band 8 at 900 MHz and Band 3 at 1800 MHz, and adds filtering to stop the two bands interfering. That overhead caps per-band gain at 60 dB uplink and 65 dB downlink. The trade-off is that the GD1000 covers every operator and both voice and data in one box, which the single-band units cannot do.
Does the GD1000 boost 5G, 3G or Band 20 800 MHz 4G?
No. The GD1000 does not boost 5G, 3G, Band 20 800 MHz 4G or Band 7 2600 MHz 4G. It boosts 2G voice on Band 8 at 900 MHz and 4G LTE data on Band 3 at 1800 MHz only. UK 5G runs on Band n78 at 3.5 GHz and Band n1 at 2.1 GHz. If you need to boost 5G home broadband or O2 and Vodafone Band 20 4G, you need the C1000 for Band 20 or a different product class for 5G.
What 4G speed improvement should a business expect from the GD1000?
In our weak-signal commercial field tests, the GD1000 lifted measured 4G download speed from a patchy 1 to 5 Mbps outside the shopfront to a steady 10 to 30 Mbps indoors once the booster was running. That is enough for HD video streaming on multiple devices, video conferencing with screen share, cloud POS terminals, and general staff browsing. The exact speed depends on how much outdoor signal the 8 dBi Yagi can pull in. If you have zero bars on Band 3 outdoors, even the GD1000 cannot create signal from nothing.
Which MVNOs are covered on the GD1000 for 2G voice?
On Band 8 at 900 MHz, the GD1000 boosts 2G voice for EE, O2, Vodafone, ASDA Mobile, BT Mobile, Virgin Mobile, Orange, T-Mobile, giffgaff, Sky Mobile, Tesco Mobile, Lebara, Lycamobile, Talkmobile and TalkTalk. On Band 3 at 1800 MHz, it boosts 4G data for EE, Three, ASDA Mobile, BT Mobile, Virgin Mobile, Orange, T-Mobile, Plusnet, iD Mobile, Smarty and Freedom Pop. Every major UK network and every major MVNO is covered on at least one of the two bands.
Can I extend the outdoor cable on the GD1000 for a larger building?
Yes. The GD1000 ships with a 10 m low-loss N-type coaxial cable, and optional extension lengths of 20 m, 30 m, 40 m and 50 m are available at extra cost. We strongly recommend adding the 18 KA lightning surge protector if the Yagi is mounted on a chimney, above roofline, or on a tall industrial building. Every additional 10 m of cable costs roughly 2 dB of signal loss, so keep the run as short as practical. DIY installation takes 30 to 60 minutes.
Do I need an Ofcom licence to install the GD1000 at my business?
No. The GD1000 is Ofcom licence-exempt, UKCA marked and CE certified. It is legal to install on your own commercial premises without applying to Ofcom, without paying an annual fee, and without notifying your neighbours. The unit is factory-tuned to UK Band 8 and Band 3 frequencies and includes automatic gain control to prevent oscillation and interference with neighbouring cell sites. Do not buy uncertified units from Amazon or eBay that are tuned to US cellular bands.
Which GD1000 upgrade accessories are worth ordering?
For a 1000 m² commercial install, we recommend three upgrades. First, the 20 m or 30 m low-loss N-type cable extension if the roof Yagi and the indoor panel are more than 10 m apart. Second, the higher-gain Yagi outdoor antenna if the serving cell tower is more than 2 km away or sits behind hills. Third, the 18 KA lightning surge protector if the Yagi is on a chimney or above roofline. The indoor 10 dBi panel is already the highest-gain option in the GD series and does not need upgrading.
