Five new radiators can mean five quick swaps or five small plumbing jobs, and the difference is what moves the price.
The Quick Answer
- Size, type and heat output for each room set the base cost of the units.
- Like for like swaps on existing tails are cheaper than moving or upsizing radiators.
- Thermostatic valves cost more than plain valves but give room-by-room control.
- Doing all five in one visit saves draining, refilling and repeat labour.
- Some cold or leaking radiators need a repair, not a replacement.
- A proper quote lists units, valves, pipework, flushing and inhibitor up front.
David Prince has over 20 years’ experience on London heating systems and heads a team of the firm’s own Gas Safe engineers, never subcontractors. Whether you need radiators or radiator replacement in Croydon, we cover the whole area.

How much for 5 new radiators?
The cost of five new radiators depends on the size and type of each unit, whether the pipework can be reused, and how much of the system needs draining and rebalancing. Swapping like for like on existing pipe tails is the cheapest route; moving positions, upsizing or adding valves and a system flush pushes the figure up.

What actually drives the price of five radiators
Five radiators is rarely five identical jobs. A small single panel in a cloakroom and a tall double panel in a through lounge sit at opposite ends of the price range, and the heat output each room needs decides which one goes on the wall. Get that wrong and you either pay for metal you do not need or end up with a cold room and a boiler working harder than it should.
The other half of the price is the plumbing. If the new radiator is the same size and sits in the same place, the existing tails often line up and the swap is quick. If the unit is taller, wider, or moving to another wall, pipework has to be altered, floorboards may need lifting and the system has to be drained and refilled. Valve choice matters too: thermostatic valves on every radiator cost more than lockshields but give you room-by-room control.

Replacing five at once versus replacing them one at a time
Doing all five in one visit is usually better value than five separate appointments. The system only gets drained once, the inhibitor only gets replaced once, and the labour is continuous rather than a series of set-ups and pack-downs. If you are having the whole set changed, it is also the sensible moment to have the system flushed so the new panels are not filled with the sludge that killed the old ones.
There are times when a staged approach makes more sense, and there are times when replacement is not needed at all. A radiator that is cold at the bottom, weeping at a valve or noisy on start-up is often a repair rather than a write-off. We handle both, so nobody is talked into five new units when three will do and two need bleeding, balancing or a new valve.

What a five radiator quote should include
A price should tell you what you are getting before anyone turns up with a van full of panels. Ours sets out the units, the valves, the pipework alterations, the draining and refilling, and any flushing or inhibitor, so there are no surprises once the job is underway. Our radiator installation services are carried out by our own engineers, never subcontracted labour, and every installation is backed by a 10 year guarantee.
Ask for the heat output figures alongside the price. That is the number that tells you the radiator suits the room rather than simply fitting the gap on the wall.

How the job runs on the day
David Prince heads a team of expert heating engineers spread across Greater London and the South East, so there are engineers working in most areas on any given day. Five radiators in an average house is typically a single day’s work, sometimes less where the pipework lines up and no floors need lifting.
Gas Safe registration is a legal requirement for anyone working on gas appliances, as the Gas Safe Register sets out, and our engineers are registered, insured and used to working in occupied homes. Dust sheets go down, water gets caught rather than dropped on your carpet, and the room is left as we found it. If something on the system fails while we are there, nine out of ten repairs are dealt with the same day rather than booked in for another week.
