Hi James - don't know anyone who has this and tbh, I am not (yet) convinced that they will be successful in reducing energy bills/CO2. I am sceptical because I don't understand the methods used for evaluating any 'real' savings.


(although I admire those who will give new/alternative technology a try) :)


sorry this doesn't answer your question, hopefully others may know.

Voltage Optimisation is a sound principle, but it risks being one of those things that charlatans capitalise on to rip off consumers.


The principle is this - electrical equipment in the UK is rated at 230v. This is the official UK supply rating, and it accommodates variations in supply when demand is high. This rating is lower than the UK 'average' supply voltage of 240v.


The difference between the 240v supply delivered, and the 230v supply that the equipment requires can mean that the equipment burns 10% more energy to work, whilst delivering no improvement in performance.


More importantly it can mean that the lifetime of the equipment is dramatically reduced - a bulb rated for 230v and supplied with 240v will effectively halve its lifetime.


So there's massive advantage if the supply can be tidied up to 230v. The National Grid cannot achieve this, so the best way to do it is locally.


The problem is that if the optimiser is badly designed it may use up all the energy it's supposed to be saving you. Hence you effectively achieve nothing.


Given the debacle over 'broadband' services, I've no doubt there will be people out there who sell 'optimisers' that do nothing of the sort.


Hence if we want to push optimisers, education and standards are key.

    • Andy is an absolute star. Have used him for years and he’s become a hugely trusted and valued friend as well as handyman. Always willing to go the extra mile and doesn’t cut corners, but great on pricing. Can’t recommend enough.
    • Surely you are still covered under these circumstances even if you don't have the physical licence? I can't believe you would be prevented from driving? That would be a ridiculous system. I don't recall any delays   when mine was renewed. Why would their medical department be involved if you have no medical issues? Could someone have made some admin mistake somewhere along the line?
    • Does anyone have the same problem.  I am 79 and have sent my licence renewal form to the DVLA on the 21st October 20 which they have received. I have just received a letter from them them dated 22 December 2025 today saying my licence is with their Drivers Medal Department and will be processed as soon as possible. This follows my telephone call to them after three weeks  from the October date as I had not received my licence back as per their time frame. I also followed this up mid December after finally getting through but did not get any confirmation as to what the situation was. Is this normal practice? On the 7 January 2026 I will be unable to drive as my licence has not been sent back. I have no medical issues and meet all the requirements with no problem as per previous renewals in fact nothing has changed health wise.Their the letter states if they need any more details from me, they will contact me directly. Why has it taken 2 and a half months get get this far? Is this some sort of ploy to get older drivers to finally give up their driving by making life difficult as possible.  Has anyone else experienced this. Read Medical not Medal.
    • You're being a little disingenuous here. It is simply not true that "the area should remain suburban 2/3 storeys maximum" because: -> the area the development is in isn't 2/3 storeys maximum today - as evidenced by the school on the lot adjoining the development to the south, as well as the similarly-sized buildings to the north and east.  -> the SPG doesn't preclude this type of development anyway. This "genie in a bottle" stuff is desperate barrel-scraping. Now you're raising the spectre of a 9 storey building on the Gibbs & Dandy site (the chance would be a fine thing) but also arguing Southwark is too slow to approve things and opposed to development more than 2-3 storeys!
