What best can mean on these listings
A useful best has a criterion you can point at. In this set that is review volume, a joule figure printed on the amazon.co.uk page, or the price of a strip that still states its surge claim. It is not a rank of the whole UK market, and it is not a Type 2 SPD in the consumer unit. Models that UK roundups often name, including other Belkin gangs and APC, were not kept here.
About £9, and a brand warranty on the pack
The Masterplug SRG4210N, ASIN B07XMZSL25, is £8.70, with four sockets, a 2 m cable, 370 joules, and power and surge LEDs. Register it for a connected-equipment warranty of up to £1,000 for three years. Daisy-chaining voids that cover. Skip it if you need a switch per socket or USB.
Where you have no room for a cable, the Masterplug three-socket adaptor, B004I5BQ42, is £8.25, with individual switches and 4.6 from 5,929 reviews. It claims surge protection and prints no joules, and reviewers say it blocks the neighbouring socket on a twin plate. Skip that adaptor if you still need the second outlet or you want a joule figure on the page.
A TV or a PC, where the joule line is printed
The Belkin BSV400, B00OE4510M, is £14.99, four sockets, 2 m, 525 joules, and 4.7 from 6,912 reviews, the largest count here. Reviewers say there are no keyholes, so skip it if the bar must be screwed to a wall.
The HANYCONY HN6090, B09LTTFM9M, is £19.99, eight AC sockets, 1.8 m, and 1,800 joules, the highest joule line in the set. Switches are per bank, and one buyer received a different USB-C count from the bullets, so skip it if you need one switch per socket or a USB layout you can trust from the photos.
One switch for a whole bench
The HANNELORE seven-gang, B0C2VPQDVK, is £29.95, with a metal body, a 3 m cable, seven sockets in one row, and one master switch. The maker prints a 2,500 W cap. Reviewers mount it under a desk or in a rack and use the switch to kill a bench or an aquarium cabinet. Surge protection is claimed and joules are not stated.
One reviewer found it too tall for a tidy 1U space, and another said switching it off tripped the house RCD. Skip it for a bedside table or for anyone who will hang a heater on those seven sockets.
What this shortlist will not call best
Nothing here is a 16 A lead: Belkin’s support page mentions a family input that must not be copied onto a 13 A plug. A higher joule number, including 1,800, is the largest energy claim printed in this set. It is not a legal grade.
The tower and the four-gang HANYCONY stay off this shortlist: joules are absent, the tower has 65 reviews, and that HANYCONY description does not state a BS 1363 plug. The checks are on the surge protector buying guide.
Common questions
What is the best surge protector in this set if I want to spend about £9?
The Masterplug SRG4210N at £8.70, with 370 joules, four sockets, and a 2 m cable, if you can register the £1,000 connected-equipment warranty. Skip it when you need a switch on each socket. If you cannot use a cable at all, the £8.25 three-socket adaptor is the other option, with no joule figure and a body that blocks the next socket on a twin plate.
What if I want the largest review count?
The Belkin BSV400 at £14.99, 525 joules, 4.7 from 6,912 reviews. Skip it when you need wall keyholes. Do not treat review text about six sockets or USB as a description of this four-gang BSV400. The £20,000 warranty on Belkin’s UK support page is not printed on this amazon.co.uk listing.
What if I want the highest printed joule figure here?
The HANYCONY HN6090 at £19.99 prints 1,800 joules, with eight AC sockets and 4.6 from 2,042 reviews. That is the largest figure in this set, not a legal grade and not proof against lightning. Skip it when you need one switch per socket. Check the USB ports on arrival, because one reviewer received one USB-C and three USB-A rather than two of each.
What if I need USB-C?
The IECOPOWER at £23.99 is the listing that claims two USB-C ports at PD 20 W, plus 1,050 joules. Some reviewers charged a MacBook from it. Several others found the ports loose or dead, and the review count is 90 at 4.4. Skip it if you cannot face a return. The tower’s USB is 2.4 A shared, which is a smaller claim, and it prints no joules.
What should I buy for a workshop or a rack?
The HANNELORE at £29.95, seven metal sockets, 3 m, one master switch, and a printed 2,500 W cap. Joules are not stated. Skip it when the television needs a joule figure, when the space is a tight 1U, or when a previous unit of this kind has tripped the house RCD. A heater still belongs in the wall, under that 2,500 W line.
Does best mean it stops lightning?
It does not. The criterion on this page is price, printed joules, or review volume inside this set. Masterplug states that this kind of lead is not a lightning arrester. In a storm, unplug the equipment. A strip also does not replace a Type 2 SPD in the consumer unit, which is an electrician’s job if you decide you want one fitted.
