They explained that separate thermostats are mandatory since 1982 so if
faulty it would have to be replaced.

On inspection they found it was not wired in the boiler (yellow wire
link across where stat would be wired) ... and no cable there, assume it
must have been 'cut out' when previous non-combi boiler was replaced 5
years ago. Honeywell stat certainly used to work with old boiler
(simple bi-metal type)

I did ask how it passed the annual boiler & controls service if it
doesn't work - no answer on that.

I think i'd be looking for a refund of that years service contract
fee.

It would not be easy or neat to run in new cables .... so I have 2
options. 1. Fit a basic Remote wireless thermostat-anybody know of a
simple one?, don't need programming options as there is a programmer
timer on the boiler.

If going to fit a thermostat I'd fit a programmable one they don't
duplicate the pure on/off time based programmer on the boiler. They
enable different temperatures based on time of day and day of week.
Being able to set a day time temp lower (when people are home and
active) than the evening (couch potato time) a bit over having just a
single temp all day/evening.

Beware of "5+2 day" ones that may only have a temperature pattern for
5 days (M-F) and two days (S & S). 7 day ones enable a different
temperature pattern each day of the week.

British gas are also preparing a quote, for this - though may do it
myself.

As well as the refund get 'em to bring it up to spec for no charge.
Do you really need the service contract? Threaten to not renew
without refund and correctional work done for no charge.
