A whole system is the one heating job where the design matters more than the kit, and it is the job most often done without one.

Each room is worked out before a single radiator is chosen.
Pipe runs are laid out so every radiator can actually get its share.
Upstairs and downstairs controlled separately where the house suits it.
Filled, balanced and tested, so the system works as designed, not just installed.
Radiator sizing comes from heat loss, which is calculated per room from its dimensions, its external wall and window area, what is above and below it, and the construction. A north facing bay fronted sitting room with a bay window and a cold floor void loses several times what a boxed in internal bedroom does, and sizing both from floor area produces one room that never warms and another that cooks.
The calculation also sets the flow temperature the system can run at, and that is what decides whether the house could later take a heat pump without re running everything.
Central Heating Installation is priced after the job has been seen, anywhere in the areas we cover. Send the postcode and a few lines about what it is doing when you contact us, and the answer comes back in writing.
An old system is often a series of tees worked out on the day, where the near radiators starve the far ones and no amount of valve setting fully fixes it. A new install is laid out so flow can be set: a sensibly sized primary, branches that are short and even, and lockshields that are reachable, which sounds trivial until somebody has to balance a system with a valve under a fitted wardrobe.
Two zones, usually upstairs and downstairs, with their own thermostats, means not heating four bedrooms at seven in the evening. In a London house with a converted loft, a third zone up there is usually worth it, because a loft behaves nothing like the rest of the house. Each zone is a motorised valve, a thermostat and a bit of wiring centre, and retrofitting one later costs several times what it costs during the install.
A new boiler on old pipework draws the old system's debris straight into it. So the system gets cleaned, a filter is fitted at the return, and inhibitor goes in and gets recorded. Then commissioning: every radiator balanced to its design flow, flow temperature set, controls programmed and demonstrated, and the figures written down. That last part is what separates a system that works from a system that is merely installed.
The age and type of property, how many rooms, and how it is heated now. Floor plans help if you have them.
