Hi I'm new to the forum and hope you can provide advice.

I recently moved to a house with a Worcester 280 Combi boiler.

The heating is proving difficult to control as it relies on
thermostatic radiator valves and no room stat is fitted. Seems pretty
expensive too as the boiler runs much more than it needs to.

A programmable room stat would be a good choice. It will take the place
not only of a stat, but does the job of timer as well.

Anyway, can I fit a room stat myself (the job seems straightfoward and
there is provision on the control board by removing a wire link and
wiring the stat in), or do I need to get an approved person to do the
work? Part L seems to refer to new installations.

Part L would probably require that a stat be fitted should the boiler
get replaced... Not sure if there is an impact on an existing install

As there will be mains power to the stat, is this classed as a new
installation under part P of building regs?

It probably is notifiable under part P. However this is one of those
cases where "doing the right thing" (i.e. paying a building notice fee
etc) will make a very significant addition to the cost (i.e. more than
the cost of the stat), and will bring no dicernable benefit to anyone
that I can see.
