Nest thermostat equivalent for my system?

Bendy_House

I thought that was the case, M-G. The 'stat part is rechargeable, I think, and topped up via a USB adaptor or similar?

In which case your plumber has misinformed you, a'tern.

It's certainly the case with Hive - the twin-channel receiver would fit (I'm pretty sure) straight on to the backplate of your current programmer, and the Prog Stat part can be mounted anywhere as it communicates wirelessly, and can be moved around too.

This is very DIYable.

The App control is gonna change yer life, 'tern

£120 for the complete 'Mini'-based kit, from Hive themselves. You can almost certainly pick up a better deal if you bide your time on t'Bay, but best to buy from proper source.

Ooh - £110 from Toolstation & Screwfix.

Wherever, make sure it's with the twin-channel receiver.

I have a boiler in kitchen with thermostat (not wired) in hall. 

The controls are in a cupboard upstairs with the hot water tank. 

Thermostat and controls communicate wirelessly. 

Plumber who renovated the system said a Nest thermostat would have to be wired to controller. He said would be expensive and not very practical as wiring would have to run along the ceiling. 

Are there any alternatives as the current controller is  difficult to program? Also we have to go upstairs to turn on/off water and heating if we are going out or adjust the thermostat which we find hard to read. 

I don’t understand what the issue with the Nest thermostat is…

My Nest thermostats are fully portable (so long as they are next to an electric plug). There are two parts to a Nest thermostat - a heat link, which is connected to the boiler and the thermostat, which can be positioned wherever you want. The thermostat and heat link communicate wirelessly with each other, with the thermostat telling the heat link what to do and the heat link turning the boiler on and off.

Exactly  - almost no different from the set up OP currently has - except current thermostat looks battery operated , The NEST thermostat unit would just need to be within reach of a mains socket

Heatlink box would replace the existing UP2 programmer and require the same cables as now

Does the Nest 'stat need constant external power?

or replace the Drayton-sourced BG with a Drayton Wiser 2-channel kit ~£130 for exactly same reasons. 
Imo is better than Hive but ymmv.
Neither will be able to make full use of the Worcester boiler's ability for modulation due to the proprietary communications protocol (EMS)  but then depending upon the boiler's age WB may not offer a control that does all that the OP might want (I am in this position).

Wow. What's the point of it being wireless, if it'll need a power cable even if wall mounted?

Baaaaaad design, Nest.

Honeywell's T6R is the same

Hive's SLT5 is absurd the other way. This is their fixed 'wired' 'stat, so doesn't need a receiver, but is wired directly to the wiring centre. Cool - can it get its power from there too?! Can it heck - it still needs batteries, albeit only three...

The Wiser looks good.

But, from personal experience, ArcticTern, the Hive will clip right in as a DIY jobbie, and you will love it. £110, or less.
