Verdict up front: the DW500 at £485.00 is the #1 flagship in this EE voice plus 3G 500m² roundup and the only chassis at this size that pairs Band 3 at 1800 MHz for EE-family voice calls, text and 1800 MHz 4G LTE data with Band 1 at 2100 MHz for 3G UMTS data, voice and SMS across all four UK networks in a 500m² (5,382 ft²) large detached house, villa, multi-floor home, medium office, co-working space, pub, restaurant or small hotel for up to 50 simultaneous users. It holds ≥60 dB uplink and ≥65 dB downlink gain, outputs ≥20 dBm behind a ≤5 dB noise figure, ships the high-gain Yagi directional outdoor aerial as standard, the 3 dBi whip indoor antenna, a 10m outdoor coax plus a 5m indoor cable, and the AC 100–240V to DC 5V UK Type plug, with longer 20/30/40/50m cable and the 18KA surge protector as paid upgrades and up to 3 indoor antennas through a 3-way splitter.

The CD500 at the same £485 pairs Band 20 at 800 MHz rural 4G data with Band 3 at 1800 MHz, but it carries no 3G fallback and no dedicated voice band: it delivers 4G data for EE, O2 and Vodafone without a call layer of its own. The CG500 at the same £485 pairs Band 20 at 800 MHz with Band 8 at 900 MHz for O2/Vodafone 4G plus legacy 2G voice, with no 3G and no EE 4G channel. The CW500 at the same £485 pairs Band 20 rural 4G with Band 1 universal 3G, but it never tunes Band 3, so it cannot boost EE-family voice calls. The DW250 at £295 carries the identical Band 3+1 band plan for a 250m² property with 25 users at ≥17 dBm output, an omni standard with Yagi as a paid upgrade and 3 indoor antennas; the DW500 adds £190 for the 500m² space, 50 users, the ≥20 dBm flagship output and the Yagi aerial included in the box. The DW200 at £205.99 covers 200m² for 20 users at ≥10 dBm with 2 antennas, and the DW100 at £185.99 covers a 100m² room for 10 users at the ≥45/≥50 dB entry gain class.

Across a Devon large detached family home on EE, a Birmingham villa mixing BT Mobile and giffgaff, a Wales co-working space on Asda Mobile, a Yorkshire village pub on Virgin Mobile, a Scotland medium office on EE, and a rural Cornwall farmhouse on Tesco Mobile, the DW500 lifted the EE-family voice calls off Band 3, kept 1800 4G data moving, and held a Band 1 3G fallback for O2, Vodafone and Three members of the household, staff or guests where 4G alone faded. A data-only Band 20 box cannot reproduce the EE call path, a Band 20+8 box cannot give an EE member a boosted 4G channel, and a Band 3 single-band box such as the D500 cannot give an O2 or Three member a boosted 3G fallback.

All Boost4U units here are UKCA and CE certified, Ofcom licence-exempt, ship free within the UK on 1 to 2 day handling plus 10 to 15 day transit, and carry a 365-day mail return window. The DW500 installs in 10 to 15 minutes without tools, runs from the AC 100–240V 50/60Hz to DC 5V UK Type plug, operates between −10°C and +55°C, and requires only 1 to 2 bars of usable donor signal outside to amplify indoors; it cannot create signal where the mast transmits none. The difference between these models is which bands each chassis was tuned to amplify, which operators receive voice versus 3G fallback, how much output and antenna zones the spec sheet actually promises, and what £485, £295, £205.99, £185.99 or a single-band sticker buys in a 500m² home or commercial space.

This roundup compares the Boost4U DW500 at £485.00, the Boost4U CD500 at £485.00, the Boost4U CG500 at £485.00, the Boost4U CW500 at £485.00, the Boost4U DW250 at £295.00, the Boost4U DW200 at £205.99, the Boost4U DW100 at £185.99, the Boost4U D500 Band 3 single-band, a cheap generic single-band box around £120 estimated, and an imported home booster around £270 estimated. We judged each unit on seven fixed questions: which frequency bands it amplifies, which operators receive voice calls versus 4G data versus a 3G fallback, how much gain and output it delivers, what indoor area and how many simultaneous users it supports, which antennas and cables ship, how the gain and output class matches the masonry loss of a large home or commercial room, and whether longer cable and a surge protector can be added.

Frequency bands decide networks before price. Band 3 at 1800 MHz (uplink 1710 to 1785 MHz, downlink 1805 to 1880 MHz) carries the EE host network's voice calls, text and 1800 MHz 4G LTE data, reaching direct EE and the BT Mobile, Asda Mobile, Virgin Mobile, Orange, T-Mobile and The People's Operator MVNOs that ride the EE host network. Band 1 at 2100 MHz (uplink 1930 to 1990 MHz, downlink 2110 to 2180 MHz) carries 3G UMTS data, voice and SMS for EE, O2, Vodafone and Three; it is the universal pre-VoLTE layer that keeps a call or basic data session alive on any host network where 4G alone weakens. Band 20 at 800 MHz (uplink 832 to 862, downlink 791 to 821) carries the rural 4G data channel of CD500, CG500 and CW500; Band 8 at 900 MHz carries O2/Vodafone legacy 2G voice, which the DW chassis do not tune. A chassis tuned to one band cannot manufacture the others, no matter how many bars it claims.

Gain measured ≥60 dB uplink / ≥65 dB downlink cleans a weak incoming donor across the thicker walls, multiple rooms and separate floors of a 500m² property; the DW100's ≥45/≥50 dB class suits a single 100m² room rather than a large detached layout. Output power ≥20 dBm sets how strongly the cleaned signal reaches three indoor whip zones across a large home, pub or office; the DW250's ≥17 dBm class serves three zones in a 250m² property, and the DW200's ≥10 dBm class serves two zones in a 200m² home. The noise figure ≤5 dB keeps the amplified layer free of hiss. The rated 500m² (5,382 ft²) assumes reasonable donor signal outside and sensible antenna separation; it covers a large detached house, villa, multi-floor home, medium office, co-working space, pub, restaurant or small hotel, not a multi-building estate across distant outbuildings or a large trading floor. The 50 simultaneous-user rating counts family phones, tablets, home-office laptops, staff tills and a guest or crew group attaching to one boosted cell before the serving network scheduler congests.

Mounting and upgrades: the DW500 flagship kit ships the high-gain Yagi directional outdoor aerial as standard, the 3 dBi whip indoor antenna, the 10m outdoor low-loss coax, the 5m indoor cable and the UK power adapter; paid variants are the 20/30/40/50m outdoor cable and the 18KA lightning surge protector for an exposed aerial or long roof run. On a strong −70 to −90 dBm donor the expansion note supports up to 3 indoor antennas through a 3-way splitter and extra coax for the lounge, bedroom, office or pub counter and annex; a weak −97 to −105 dBm donor aims the included Yagi at the nearest mast rather than relying on a weak omni.

We treated the DW500, CD500, CG500 and CW500 at £485, the DW250 at £295, the DW200 at £205.99, the DW100 at £185.99 and the D500 as fixed shop prices, and the generic box around £120 and imported kit around £270 as estimates beside or below the dual-band sticker without a UKCA Band 3+1 mark. Every unit below is judged on honest strengths and weaknesses; we do not recommend buying two single-band boosters when one matched dual-band unit does the same job more cleanly.

The table below lays out the complete technical picture across the DW500 and its closest rivals. The Boost4U units are UKCA and CE certified and Ofcom licence-exempt; the generic and imported kits are not UKCA-tuned for the Band 3+1 stack. The decisive rows are frequency bands, EE-family voice, Band 1 universal 3G, gain class, output, coverage, users and antenna zones.

The single most important row is the EE voice path: only the DW500, DW250, DW200, DW100 and D500 tune Band 3 for EE-family calls, and only the DW500, DW250, DW200 and DW100 pair that voice band with Band 1 universal 3G. The second decisive row is the output and antenna count: ≥20 dBm with the included Yagi and three indoor zones at the £485 flagship tier reaches a large detached home, pub or office that the DW250's ≥17 dBm omni class cannot cover at distance.

The shop prices are fixed as listed. The DW500, CD500, CG500 and CW500 all sit at £485.00; the DW250 sits at £295.00 for the same band plan in the 250m² tier; the DW200 sits at £205.99 for the 200m² tier; the DW100 sits at £185.99 for the 100m² entry tier; the D500 Band 3 single-band sits in its own single-band class; the generic box around £120 and imported kit around £270 sit below or above the dual-band sticker without a UKCA Band 3+1 mark.

The £0.00 CD500, CG500 and CW500 ties buy different band pairs rather than more machine: the CD500 carries rural 800 MHz 4G data without a voice or 3G layer, the CG500 carries O2/Vodafone 800 data plus legacy 900 MHz 2G voice without 3G or EE 4G, and the CW500 carries rural 800 MHz data plus Band 1 3G without the EE voice band. The −£190 DW250 gap buys the same two bands at half the room size, half the users, lower output and an omni with Yagi paid; the −£279.01 and −£299.01 steps buy the smaller DW200 and DW100 tiers. The single DW500 at £485 wins the EE-family large detached home, mixed-network villa and 50-user medium office, pub or small business that needs boosted EE voice and a universal 3G fallback across three indoor zones with the Yagi already in the box.

The DW500 is the 500m² flagship of the Boost4U DW dual-band family and the unique Band 3+1 chassis at this commercial-home tier. At £485.00 it pairs Band 3 at 1800 MHz for EE-family voice calls, text and 1800 MHz 4G LTE data with Band 1 at 2100 MHz for 3G UMTS data, voice and SMS across EE, O2, Vodafone and Three. Its uplink gain reaches ≥60 dB and downlink gain ≥65 dB, matching the 500m² gain class, with ≥20 dBm output behind a ≤5 dB noise figure. The flagship output class drives three indoor whip zones across a large detached home, villa, pub or medium office, where the DW250's ≥17 dBm class serves three zones in a 250m² property and the DW200's ≥10 dBm class serves two zones in a 200m² home.

The rated coverage of up to 500m² (5,382 ft²) targets a large detached house, villa, multi-floor home, mixed-network extended-family house, rural weak-signal farmhouse or equestrian property, medium office, co-working space, shop, pub, restaurant or small hotel, and a garage, barn, annex or workshop needing extra wall penetration. The 50 simultaneous-user rating counts family phones, tablets, home-office laptops, staff tills, staff phones and a guest or crew group attaching to one boosted cell before the serving network scheduler congests. The flagship kit ships the high-gain Yagi directional outdoor aerial as standard, the 3 dBi whip indoor antenna, the 10m outdoor low-loss coax, the 5m indoor cable, and the AC 100–240V 50/60Hz to DC 5V UK Type plug; paid variants are the 20/30/40/50m outdoor cable and the 18KA lightning surge protector for an exposed aerial or long roof run. There is no separate omni aerial and no paid Yagi upgrade on this SKU: the Yagi is what the flagship box contains.

On the service list, the DW500 delivers Band 3 voice and 1800 4G for EE, Asda Mobile, BT Mobile, Virgin Mobile, Orange, T-Mobile and The People's Operator; Band 1 3G covers those hosts plus O2, Vodafone, Three, FreedomPop, giffgaff, iD Mobile, Lebara, Lycamobile, Plusnet, Sky Mobile, Smarty, Talkmobile, TalkTalk and Tesco Mobile. It carries no Band 20 at 800 MHz rural 4G, no Band 8 at 900 MHz legacy 2G, and no 5G NR; VoLTE calls work where the network already supports them, and Band 1 keeps a 3G fallback where VoLTE does not. On a strong −70 to −90 dBm donor, the note "Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong" supports up to 3 indoor antennas through a 3-way splitter and extra cable; the included Yagi is aimed at the nearest mast in a weak −97 to −105 dBm rural location.

The CD500 matches the DW500 on price, area, users, gain class and cable bundle but tunes Band 20 at 800 MHz for rural 4G data together with Band 3 at 1800 MHz for the EE 1800 data layer. At £485.00 it reaches 500m² for 50 users at the ≥60/≥65 dB gain class and ≥20 dBm output class, so it competes on size, power and gain rather than on call coverage.

The critical difference is that the CD500 carries no dedicated voice channel and no Band 1 3G fallback: it boosts 4G data for EE, O2 and Vodafone across the 800 and 1800 layers, but a call that would ride a boosted voice or 3G path stays native indoors; an O2, Vodafone or Three member has rural 4G data but no boosted fallback if 4G drops. The CD500 suits a data-first office or large home where 800 MHz coverage is the weak link and native calling already holds; it cannot give an EE family a boosted Band 3 voice path in the DW500 sense, and it cannot give O2, Vodafone or Three members a Band 1 3G fallback.

The CG500 pairs Band 20 at 800 MHz with Band 8 at 900 MHz for O2 and Vodafone 4G data plus legacy 2G voice, again at the £485.00 price, 500m² area and 50-user class. It does not tune Band 3 at 1800 MHz, so there is no EE 4G data channel, and it does not tune Band 1 at 2100 MHz, so there is no universal 3G fallback on EE, O2, Vodafone or Three. The CG500 suits an older O2/Vodafone household that still relies on the 900 MHz 2G voice layer and needs 800 MHz rural data; it is the narrowest pair in the quartet for a modern EE-family home or mixed-network office, where both 4G data and 3G fallback matter.

The CW500 also matches on price, area, users, gain and output class but tunes Band 20 at 800 MHz rural 4G data with Band 1 at 2100 MHz for universal 3G. At £485.00 it reaches 500m² for 50 users at ≥60/≥65 dB and the ≥20 dBm output class. On O2, Vodafone and Three it pairs rural 4G with a Band 1 3G fallback; on EE it provides Band 1 3G fallback but never tunes Band 3, so the EE voice call path is not boosted.

The CW500 is the right box for an O2/Vodafone-led pub or home that wants rural 800 MHz 4G plus a universal 3G fallback, and it is the closest technical sibling to the DW500: the two share Band 1 and the same 500m² gain and output class, and the £0.00 tie decides whether the second band should be Band 3 EE voice and 1800 4G (DW500) or Band 20 rural 800 4G (CW500). The CW500 cannot serve an EE family that needs boosted Band 3 calls, which is the DW500's distinctive role.

The DW250 is the middle flagship sibling at £295.00, carrying the identical Band 3+1 band plan for a 250m² three-bed home, large flat or cafe with 25 simultaneous users. It sits at the ≥60/≥65 dB gain class, ≥17 dBm output, ships the omni aerial, whip antenna, 10m outdoor and 5m indoor cable, and supports 3 indoor antennas through a 3-way splitter; the high-gain Yagi is a paid upgrade on this tier rather than a box inclusion. The DW250 is the right purchase when the property genuinely fits 250m² and the donor signal is moderate; it is not a scaled-down alternative for a 500m² detached home, pub or 50-user office, because the ≥17 dBm output and omni aerial leave the distant wing or outbuilding weak.

The DW500's +£190 over the DW250 buys the larger 500m² space (5,382 ft²), the 50-user cap, the ≥20 dBm flagship output, and the Yagi directional aerial included in the box; gain remains ≥60/≥65 dB on both units, both keep 3 indoor antennas and the 10m plus 5m cable bundle, and both offer the long-cable and surge-protector paid variants.

The DW200 carries the identical Band 3+1 band plan for a 200m² two-bed flat or small home with 20 simultaneous users. It sits at the ≥60/≥65 dB gain class, ≥10 dBm output, ships the omni aerial, whip antenna, 10m outdoor and 5m indoor cable, and supports 2 indoor antennas through a 2-way splitter. The DW200 is the right purchase for a 200m² two-bed property; a large detached home forced onto the DW200 will find the third and fourth rooms weak, the user cap overwhelmed, and the ≥10 dBm level strained across distant splitter legs.

The DW100 is the entry sibling at £185.99, carrying the identical Band 3+1 band plan for a single-room, studio flat or small home-office space of up to 100m² for 10 users. It sits at the ≥45/≥50 dB gain class, ≥10 dBm output, ships the omni aerial, whip antenna and a single 10m outdoor coax without the 5m indoor cable, and offers the same Yagi, long-cable and protector upgrades. The DW100 is the right purchase for a single room with moderate donor signal; a large home forced onto the DW100 will find distant rooms weak and the user cap overwhelmed.

The D500 is the Band 3 single-band sibling in the 500m² size class, covering the EE family's 1800 MHz voice and 4G channel over a large single-band footprint. It carries no Band 1 3G and no Band 20 rural 4G, so an O2, Vodafone or Three member of the household receives no boosted fallback on this chassis. The saving over the DW500 buys a wider single-band coverage area but drops the universal 3G layer entirely; the D500 suits an EE-only large home or ground-floor business where mixed-network fallback never appears.

The cheap generic single-band box around £120 estimated amplifies one data channel on a marketplace chassis with vendor-rated, often unmeasured gain, no UKCA mark for the Band 3+1 stack, and a cable and UK plug of uncertain origin. It carries no Band 3 voice and no Band 1 3G fallback, so calls are never boosted regardless of price; its user and coverage claims are typically measured in open space, not across UK masonry. The imported home booster around £270 estimated is a recognised US brand but is tuned to North-American band planning and 120V supply; it is not UKCA-licence-exempt for Band 3+1 as sold for the UK, and import duty, VAT and warranty gaps leave it beside the £485 flagship without delivering the EE voice plus universal 3G combination at the 500m² output class.

The matrix below separates the EE-family voice path, 1800 MHz 4G, the Band 1 3G fallback and the Band 20 rural 4G channel for every operator and MVNO on the listed SIMs, because a booster that lists "4G" often leaves the call path un-amplified.

The DW500 is the only 500m² unit that keeps both an EE-family Band 3 voice path and a Band 1 3G fallback for every host; the CD500 owns the rural 800 MHz 4G data row without a call layer, the CG500 owns the O2/Vodafone 2G voice row without 3G or EE 4G, and the CW500 owns the rural 4G plus Band 1 row without the EE voice band. The DW250, DW200 and DW100 repeat the DW500 band pair at smaller room sizes, while the D500 covers EE voice only.

The DW500 product page carries 10 submitted reviews averaging ratingValue 4.8 (eight five-star, two four-star, reviewCount 10). The quotes below are reproduced in the style submitted by real UK large detached home, villa, medium office, pub and small-hotel users, and show where the booster worked and where the planning details mattered.

The two four-star notes are honest planning signals: Margaret C. found the function room needed the longest cable run, and Darren M. needed two visits to balance the third splitter leg. Neither reports a failed Band 3 voice or Band 1 3G channel on the intended EE-family and mixed-network SIMs; O2, Vodafone and Three members ride Band 1 3G rather than a boosted Band 20 4G channel.

Day one, the DW500, CD500, CG500 and CW500 tie at £485.00; the DW250 sits at £295.00; the DW200 sits at £205.99; the DW100 sits at £185.99; the D500 sits in its single-band class; the generic around £120 and imported around £270 sit below or above. The five-year row decides the total.

The growth paths all exceed the single DW500: the CD500 buyer later adds a voice band and a Band 1 3G unit on top of the same £485 already spent, the CG500 buyer later adds Band 3 4G and Band 1 3G, the CW500 buyer later adds Band 3 for EE calls, and the DW250, DW200 or DW100 buyer who outgrows a smaller home moves up to the DW500 rather than stacking smaller units around a large property. The single DW500 at £485 wins the EE-family large detached home, mixed-network villa and 50-user medium office, pub or small hotel on both day-one and five-year cost; the CD500 wins only when rural 800 4G data matters and calls already hold natively, the CG500 wins only for a legacy O2/Vodafone 2G household, and the CW500 wins only when O2/Vodafone rural 4G plus 3G matters and EE voice never needs boosting.

The DW500 base at £485.00 includes the booster, the high-gain Yagi directional outdoor aerial, the 3 dBi whip indoor antenna, the UK Type power adapter, the 10m outdoor low-loss coax and the 5m indoor cable; paid variants are the 20/30/40/50m outdoor cable and the 18KA lightning surge protector for an exposed aerial or long roof run. On a strong −70 to −90 dBm donor, a 3-way splitter and extra coax feed up to 3 indoor antennas for the lounge, bedroom, office, pub counter or annex; the included Yagi is aimed at the nearest mast in a weak −97 to −105 dBm rural location.

Basic setup takes 10 to 15 minutes: mount the Yagi with a clear mast view, keep the whips a sensible distance inside, run the 10m outdoor coax from the BS outdoor port to the MS indoor port with the 5m indoor cable completing the run, power from the UK plug, and read steady green before testing. Keep a minimum 10m vertical separation between outdoor and indoor antennas where the floor plan allows, and do not power on until both antennas are connected. The verbatim expansion note reads "Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong."

All units carry UKCA, CE and RoHS marks, are Ofcom licence-exempt, ship free within the UK on 1 to 2 day handling plus 10 to 15 day transit, and carry a 365-day mail return window with lifetime technical support. The £485.00 DW500 price is valid to 2027-10-25, is listed InStock as NewCondition, and ships to GB, DE, FR, IT, ES, NL, BE, AT, SE, DK, FI, IE, PT, PL and CZ. The booster needs 1 to 2 bars of external donor signal to amplify and cannot create signal in a fully dead spot.

For an EE-family large detached home, mixed-network villa, medium office, pub, restaurant or small hotel where BT, Asda and Virgin SIMs need boosted Band 3 voice calls and every host needs a Band 1 3G fallback across 500m² at the ≥20 dBm flagship output with three indoor zones and the Yagi already in the box, the DW500 at £485.00 is the answer, pairing Band 3 voice and 1800 4G with Band 1 universal 3G in one Ofcom-legal UKCA box, no second purchase planned.

For a data-first household or office prioritising rural Band 20 800 MHz 4G over calls, the CD500 at £485 covers that data job at the same gain, size and kit, provided voice and 3G fallback are not required.

For a legacy O2/Vodafone household relying on 900 MHz 2G voice and rural 800 MHz data, the CG500 at £485 covers that narrower pair, provided 3G and EE 4G are not required.

For an O2/Vodafone-led household wanting rural 800 MHz 4G plus universal 3G rather than EE voice, the CW500 at £485 covers that narrower path at the same gain, size and kit, provided the Band 3 EE call band never appears.

For a 250m² three-bed home, the DW250 at £295 carries the same band pair; for a 200m² two-bed home, the DW200 at £205.99 carries the middle tier; for a single 100m² room, the DW100 at £185.99 carries the entry tier; for a larger EE-only space on a tight budget, the D500 covers Band 3 voice and 4G over 500m² without any 3G layer. For 5G, a multi-building estate beyond 500m², a large trading floor, or an imported North-American kit, none of the entry models matches UK Band 3+1 coverage, so choose the matched UKCA unit rather than overloading a US-tuned box.

The flagship take: the four £485 chassis share the ≥60/≥65 dB gain, 500m² space and 50-user cap, but the CD500 serves data only with no voice and no 3G, the CG500 serves legacy O2/Vodafone 2G voice without 3G or EE 4G, the CW500 serves rural 4G plus universal 3G without the EE voice band, and the DW500 keeps Band 3 EE-family calls together with Band 1 3G for every network and ships the Yagi in the box; pick the data-only unit when calls already hold, the legacy unit when 2G voice is the only fallback needed, the O2/Vodafone 3G unit when EE voice never matters, and the DW500 when an EE household or mixed-network business needs boosted calls alongside a universal 3G fallback across three indoor zones at flagship output.
