Fix malfunctioning Nest thermostat system

£120

Peckham, Greater London, SE15

14th Mar 2026

I have 2 Nest thermostat units on the first floor which don't turn on, but the units on the ground floor and top floor do. As far as I can tell the base plate (white square one) on the first floor is not receiving power. But there is a Heatmiser UH6 on the first floor which seems to be working correctly. I'm looking for someone who can identify and fix the issue. Let me know if you need additional details.

Fire alarm battery change

£20

Turnpike Lane, Greater London

4th Jan 2026

Our alarm needs changing batteries but we've no step ladder and it's in a very awkward position on the upstairs landing above the stairs and the ceiling is high. Not entirely sure what batteries needed as first time we've changed it. Would be great to get it sorted and have correct batteries refitted safely, or if it just needs a reset - for that to be done. Quick help would be great as we've had a neighbour mention it.
