    Question. Signal for hot water not getting through

    Hi all, 
 After boosting the hot water for probably too long on our pulsacoil thermal storage, the circuit breaker was tripped and I saw that the timer unit had melted through. 
 I got a replacement unit and have installed it and flicked the circuit breaker switch back on. The water seems to be...

    Paying yourself through a Ltd as a subby

    When starting out subbying, a few people suggested to me that I should start out as ltd. As I would already be paying agencies/umbrellas £20 a week to receive my wages (£1040~ a year) it would work out cheaper to go Ltd and pay an accountant. Subsequently I had a meeting with an accountant and...

    Oops. Drilled through a cable.

    Stupidly, I drilled through an FP cable, close to a Call Point. It’s plastered into the wall. Now, Can I chase and reveal the cable, crimp the conductors, use heatshrink and plaster back in? It would be a hell of a lot easier than any other method but I want to do it correctly. Cheers in...

    E7 with 2 meters (on/off peak), but current only goes through one?

    Hi folks, We moved into a new flat about 6 months ago and have realised we're being billed for all of our electricity at the expensive "all day" rate - despite having a very large "Thermaflow" electric boiler which is designed to draw tons of power heating up water overnight to use throughout...

    Advice after drilling through electrical cable above plug socket

    Hi all, I have stupidly drilled through the same electrical cable TWICE 1 inch apart. This is above a twin plug socket which obviously now doesn’t work. The holes are about 1m above the socket.
