Top Mobile Phone Signal Boosters In The UK

The UK, just like everywhere in the world, is full of people suffering through your common signal issue, but with the advent of boosters, the problem can be lessened if not eliminated. However, not every tool is created equal, and you’ll have to sift through as much as you can to find the best mobile phone signal booster in the UK according to UCtel. Once you find the top units, in theory, your signal issues are entirely solved.

Now, finding these units required a look at a host of qualities each possessed and below, we’ll look at each, all before talking about the best one. So, let’s do this!


What makes a good unit?


For those who aren’t in the know, boosters are units consisting of multiple components coming together to draw in, amplify, and redistribute existing signals, allowing for faster internet, and better calls. The components they consist of are as follows:

  • An external antenna that’s fitted outside, on the highest point of the place in need, and gathers the signal
  • An amplifier fitted inside the place in need, and boosts the signal
  • An internal antenna (or multiple to increase coverage) fitted in an area that needs the boosting the most
  • Coaxial (sometimes fiber optic) cable that connects the above components, and limits signal loss


For those who are aware of what boosters are, going through the above may be seen as time-wasting. However, one of the factors considered when looking for the top mobile signal boosters in the UK tackles only one of the above components, which we’ll get to soon enough. With that out of the way, let’s begin talking about the factors considered when finding the best tool:


The unit’s legality

The legality of boosters in the UK is a big deal. All technology has to be deemed legal, and in compliance with the exemptions in Section 8 of the WT Act 2006, as offered by Ofcom, the regulatory body in the UK.

Anything not in compliance will result in fines upwards of £5,000, and possible jail time of up to a year. Fortunately, the examples we’ll talk about are entirely legal, even including Ofcom’s 2022 exemption extension that requires that repeaters can support 2g and/or 3g.


The unit’s strength

This is where knowledge about the different components of boosters comes into play, as one of them, the amplifier, needs to be strong enough to cover a designated area. The signal is measured in decibel-milliwatts (dBms), and depending on what your situation needs, anything from the average of -99dBms to the excellent -50 (dBms) could work for you.

Now, amplifiers are rated in decibels (dBs), which are expressed in a positive number(20dB), and the higher the rating, the stronger the outside signal can be boosted. This means more coverage, but that depends on what you need, as a car won’t require the same amplifying power an office building does.


The amount of carriers the unit holds

 Units can come in singular, and multiple network carrier versions. The choice between both options depends on whether you want stability or variety. Single carrier boosters are more stable, but switching carriers is a hassle, so you might want to have the alternative.

Pricing is also another aspect that you should think about. However, with the units we’re about to go through, it all varies according to whom you purchase from.



The best units out there


Now that we have some criteria, we can begin looking at the best this nation has to offer. Without further ado, let’s look at some examples:


Cel-Fi’s GO X


This booster lands on this list due to several factors, the primary of which is its single carrier status, which means that a 100dB gain is possible. With this amount of power, and it being a single carrier, weaker signals can be boosted to such an extent that upwards of 1,400 square meters can be covered. While it’s built for your small home and office, vehicles can utilize it as well. To sum things up, look at the following:

  • They’re fairly easy to set up
  • They can support anything from 3g to 5g
  • They are versatile, fitting in small buildings, and cars
  • Only one carrier can be supported at a time


Cel-Fi’s QUATRA 4000e


This DAS hybrid( a Distributed Antenna System that uses both active and passive means to boost and distribute signals) has 100dB of gain for the four networks it can support. The reason one would think this is the best mobile signal amplifier in the UK, outside the above is the up to six coverage units possessed. This makes it very scalable, allowing for greater areas upwards of 11,600 square meters. Some of this and more can be summed up as the following:

  • Four carriers can be boosted
  • Its large coverage can cover large building
  • It’s the most expensive of the varieties presented here due to its complexity, with some dealers charging over $19,000
  • Configuration and management can be done remotely
  • It can also cover between 3G and 5G
  • Its use hybrid DAS nature uses fiber optic cable that suffers the lowest amount of loss


Cel-Fi’s Prime


This tool has integrated antennas, which means cabling or an external antenna isn’t necessary. Despite all this, these single carrier boosters can amplify signals up to 80dB for both 3g and 4g, for a 100 square meter coverage. Its notable aspects are as follows:

  • It’s the easiest variety to install on the list
  • Connecting to it helps preserve your device battery
  • It’s built especially for small rooms


Final thoughts


Given the benefits of boosters, the last thing you want is a faulty tool or one that doesn’t comply with Ofcom regulations. Anything that can be considered the best mobile signal booster in the UK has to meet that standard first, and afterwards, everything is subjective. The above shows that the best booster doesn’t really exist, because it has to meet your specific needs.

What the above examples show are three of the best boosters that suit certain individuals or groups. Other great boosters are out there, but you need an experienced, knowledgeable dealer to help find your match.
