Russell griffiths Posted December 30, 2020 Posted December 30, 2020 Is surge protection still a thing??? im planning location of sockets at the moment and have got to my wife’s office, it will be full of all computer type stuff, so should the computer go through a surge protection socket of some description. Also what about television and stuff located in the front room.
TonyT Posted December 30, 2020 Posted December 30, 2020 It’s now in BS7671 SPD modules can be fitted in consumer unit protecting. Whole installation, retro fitted afterwards to protect whole installation. 1
Onoff Posted December 30, 2020 Posted December 30, 2020 It's basically a requirement of the 18th edition regs. The designer can avoid it if a risk assessment is carried out. Think though about how many things in a modern house could be fubar'd from a surge, be it from the supply side or atmospherics. From white goods to boiler controls along with the obvious mains connected routers, pcs etc. You might be able to mod your cu and do it up front or just individual circuits. 1
Russell griffiths Posted December 31, 2020 Author Posted December 31, 2020 Any idea what is added at the CU to do this.

Considering retrofitting one of these https://www.electricaldirect.co.uk/product/danson-100a-main-switch-4-modules-metal-consumer-unit-with-spd-type-2-750647
Oz07 Posted December 31, 2020 Posted December 31, 2020 Got one in my cu. Wasn't officially a reg at the time bit was close and sparky said that's the way it's going.
Russell griffiths Posted December 31, 2020 Author Posted December 31, 2020 Thanks all will talk to the sparky.
Mr Punter Posted March 10, 2021 Posted March 10, 2021 Just resurrecting this. I have some small flats / studios with plastic CUs and no RCD, so I need to have metal CUs fitted. Is surge protection now mandatory?
TonyT Posted March 10, 2021 Posted March 10, 2021 https://www.expertelectrical.co.uk/delivery/ metal and RCD yes. spd your call but for all it costs see attached link as an example

I was looking at swapping for these https://www.screwfix.com/p/british-general-12-module-6-way-populated-high-integrity-dual-rcd-consumer-unit/4674g The wiring is fairly new and there are 8 small flats in the building.
TonyT Posted March 10, 2021 Posted March 10, 2021 It’s the risk assessment part that could come to bite you in the backside if you didn’t do it or fit SPD and are renting them out and lightning damage occurred the website I linked to has surge protection and a mcb so takes 2 ways space in a consumer unit for less than £30 its the ‘fuse box range’ indeed they have a metal board with dual RCD and SPD fitted starting from £97. Just require extra mcbs at £2 each.
Onoff Posted March 10, 2021 Posted March 10, 2021 (edited) You could go SPD and all double pole RCBOs... SBS-Price-List-2021.pdf Edited March 10, 2021 by Onoff
Mr Punter Posted March 11, 2021 Posted March 11, 2021 Thanks @Onoff and @TonyT. I went for MK boards with surge protection and 2 x type A RCDs in the end. Cost an extra £430 over the 8 flats but hopefully more future proof.
