USB sockets have become one of the most requested electrical upgrades in Kent homes over the past five years. With smartphones, tablets, wireless headphones, smartwatches and countless other USB-powered devices now part of daily life, the standard three-pin socket with a bulky adaptor simply feels outdated. USB outlets built directly into your wall sockets offer a cleaner, more convenient and safer way to charge.
As NAPIT registered electricians who have fitted thousands of sockets across Deal, Dover, Canterbury and all of Kent, we put together this complete guide to USB socket installation. We cover the different types available, where to install them, safety considerations, costs and everything else you need to know before upgrading.
What Is a USB Socket?
A USB socket looks like a standard double socket but includes built-in USB charging ports alongside — or in place of — the traditional three-pin outlets. Most modern USB sockets include a combination of USB-A and USB-C ports, allowing you to charge the vast majority of devices directly without using an adaptor.
Unlike plugging a phone charger into a standard socket, USB outlets deliver power directly from your home's 230V supply through an internal transformer. This is more efficient than most plug-in adaptors, generates less heat, and frees up your three-pin sockets for appliances that actually need them.
USB-A vs USB-C: What's the Difference?
USB-A is the older, rectangular port that most people recognise. It typically delivers 5V at up to 2.4A, giving roughly 12W of charging power — enough for overnight charging of phones and tablets, but relatively slow by modern standards.
USB-C is the newer, oval-shaped port that has become standard on nearly all new devices. USB-C sockets installed by electricians can support USB Power Delivery (PD), delivering up to 20V at 3A — that's 60W, enough to fast-charge smartphones, tablets and even many laptops. If you own a newer iPhone, iPad Pro, Android device or USB-C laptop, a USB-C outlet is the fastest and most future-proof choice.
Most of our Kent customers now opt for sockets that include both USB-A and USB-C ports — usually two of each — giving maximum flexibility for households with a mix of old and new devices.
Where Should You Install USB Sockets?
Bedrooms: Beside the Bed
This is the most popular location for USB sockets. A double socket with USB ports beside each bedside table eliminates the need for multiple adaptors and trailing cables. You can charge your phone, smartwatch and wireless earbuds overnight while keeping the main three-pin sockets free for lamps.
Kitchen: Worktop and Island
Kitchens are where tablets are used for recipes, phones are propped up for video calls and Bluetooth speakers need regular charging. USB sockets on kitchen worktops and islands keep these devices powered without cluttering your main sockets with adaptors.
Home Office: Desk Level
A home office desk should have at least one double socket with USB ports within easy reach. This powers your laptop via USB-C (if supported), charges your phone and handles wireless mouse or keyboard charging — all without crawling under the desk to find a spare socket.
Hallway: Near the Front Door
A USB socket near your front door is incredibly convenient for topping up your phone before leaving the house, or for guests who need a quick charge. It's also the ideal location for a smart doorbell transformer.
Living Room: Behind the Sofa
Behind the sofa is where phones are dropped while watching TV, where wireless headphones live, and where gaming controllers need charging. USB sockets in this location eliminate the cable chaos that usually accumulates around the living room.
Are USB Sockets Safe?
Yes — when installed by a NAPIT registered electrician. All USB sockets we install in Kent meet BS 7671 wiring regulations and carry CE or UKCA marking for electrical safety. The internal transformers are protected against overcurrent, overvoltage and short circuits.
However, cheap unbranded USB sockets bought online can be dangerous. We have seen outlets with inadequate insulation, poor solder joints and no overcurrent protection. Always choose reputable brands like MK, Hamilton, Schneider or British General, and always have them installed by a qualified electrician who can test and certify the work.
Do USB Sockets Use Electricity When Not in Use?
Modern USB sockets draw a tiny amount of standby power — typically less than 0.3W when idle. At current UK electricity prices, this works out to roughly £1–£2 per year per socket. The convenience and safety benefits far outweigh this negligible cost.
How Much Does USB Socket Installation Cost in Kent?
A standard double socket with two USB ports installed by L Fowler Electrical typically costs between £110 and £180 in Kent, depending on the brand, location and how the cable needs to be run. Installing multiple sockets at the same time is more cost-effective — we often fit 4–6 USB sockets across a home in a single day for a reduced per-point rate.
Premium finishes such as brushed steel, chrome or matte black cost slightly more than standard white plastic. USB-C PD sockets that deliver higher power for laptops also carry a small premium over basic 12W USB-A outlets.
We cover all of Kent including Deal, Dover, Canterbury, Folkestone, Margate, Ramsgate, Broadstairs, Faversham, Whitstable, Herne Bay, Ashford, Sittingbourne and all surrounding villages.

Why Upgrade to USB Sockets?
USB sockets are one of the most cost-effective electrical upgrades you can make. They declutter your home by eliminating bulky adaptors, free up three-pin sockets for appliances, charge devices faster than most plug-in adaptors, and add a modern touch that impresses buyers if you ever sell. In our experience across Kent, USB sockets are the single upgrade that homeowners say they wish they had done sooner.
