It differs from a full radiator installation in that the pipework and heat emitter positions usually already exist and are staying put; the job is choosing the correct replacement, matching it to the existing pipe centres or adjusting them, and refitting it properly. We offer this two ways: supply and fit, where we source and price the radiator for you, or labour-only, where you have already bought a specific column, designer radiator or towel rail and want it fitted correctly. ### Who it is for Homeowners with a single radiator that has failed, corroded or pinholed, anyone replacing a plain panel radiator with a column or designer model for looks, bathrooms needing a heated towel rail instead of a radiator, and people who have bought a radiator online or in a showroom and just need it fitted properly with the pipework, valves and balancing done right. ### When you need it When a radiator is weeping at a joint, staying cold along the bottom edge even after bleeding and cleansing elsewhere in the system, has visible rust staining under it, or when you are redecorating and want to change the style before the wall goes back to a fresh coat of paint. It is also worth doing before a kitchen fitting or extension, where the radiator needs to be moved or removed entirely to make way for new units or an opened-up space. ### Why it needs a registered engineer A replacement done badly does not just look untidy, it changes how the whole system behaves. Fit a radiator with a lower output than the one it replaced and the room gets colder, not warmer, however new it looks. Reuse valves that were already weeping and the new radiator is fitted onto an existing leak. Skip re-dosing inhibitor after the system has been drained down and every radiator on the circuit, not just the new one, starts corroding a little faster from that point on.

Our process ## How We Carry Out the Work, Step by Step - 1 ### Step 1: Assessment and sizing check We look at the radiator being replaced, measure the room if the output is in any doubt, and check whether the new radiator you have chosen, or the one we are supplying, will actually heat the room properly rather than just fit the space on the wall. - 2 ### Step 2: Supply and fit, or labour-only quote in writing If we are sourcing the radiator, you get the make, model, output and total price in writing. If you have already bought your own radiator, we quote the fitting labour once we have confirmed the pipe centres, valve type and wall fixings will work. - 3 ### Step 3: Isolation and removal The system or the individual radiator circuit is isolated, the old radiator is drained and removed, and we check the condition of the pipework, brackets and wall behind it before the new one goes up. - 4 ### Step 4: Fitting, valves and pipework New brackets are fixed into sound substrate, valves are fitted or replaced as needed, and pipework is adjusted where the new radiator's centres or connection points differ from the old one, whether that is a straightforward swap or a radiator moved to a new position for a kitchen or extension. - 5 ### Step 5: Refill, inhibitor and balance The system is refilled, dosed with inhibitor to replace what was lost during the drain-down, fully vented, and the whole system is balanced so the new radiator does not draw flow away from the rest of the house. What you get ## The Difference It Makes ### Correct output, not just a new box on the wall We check the replacement will actually heat the room properly rather than assuming a like-for-like swap by size alone is good enough. ### Supply and fit or labour-only, your choice Buy your own column, designer radiator or towel rail and we will fit it properly, or let us source and price the whole job for you. ### Cold-bottom radiators diagnosed properly We check for sludge and debris inside the radiator rather than treating every cold spot as an air lock that bleeding will fix. ### System balanced afterwards, not just the new radiator connected Every radiator on the circuit is checked and balanced so replacing one does not quietly leave another lukewarm. ### Fixed written price before work starts You know the total cost, whether that is a supply-and-fit price or a labour-only quote, before anything is disconnected. ### Radiators moved for kitchens and extensions We can relocate or remove a radiator entirely to suit a new kitchen layout or an extension, capping off or extending pipework properly rather than leaving a visible stub. In detail ## Choosing, Sizing and Fitting a Replacement Radiator Heat output is measured in BTUs or watts, and it is the single most important number when replacing a radiator, more important than the pipe centres or the finish. A column radiator or a slimline designer radiator can look substantial on the wall while actually having less surface area, and therefore less output, than the plain panel radiator it is replacing. We work out the room's heat requirement and check any proposed replacement against it, rather than assuming that because a radiator looks similar in size it will perform the same. This matters just as much on a labour-only job where you have chosen the radiator yourself; we will tell you before fitting day if the output looks short for the room. A radiator that stays stubbornly cold across the bottom, sometimes across the whole bottom third, after the top has bled clear and warmed up properly, is very rarely still an air problem. It is almost always sludge, rust and debris that has settled in the base of the radiator body over years, insulating that section from the hot water flowing above it. Bleeding will never clear this because there is no air trapped there to release. The proper fix is either a thorough power flush of the whole system, or in cases where a single radiator is particularly bad, removing it, flushing it out separately on the ground with a hose, and refitting it with fresh valves and inhibitor. Column radiators and designer radiators bring their own fitting considerations beyond output. Column radiators are heavier than an equivalent panel radiator and need brackets fixed into sound masonry or timber, not just plasterboard, especially on taller and wider models. Vertical and horizontal designer radiators often have valve connections in different positions to a standard panel radiator, which means the existing pipework sometimes needs extending, shortening or rerouting rather than simply reconnecting to the same spot on the wall. Heated towel rails in bathrooms need the same output check as any other radiator: a rail that looks the part but is undersized for a family bathroom will leave both the room and the towels underheated. Thermostatic radiator valves and lockshield valves are worth replacing at the same time as the radiator itself if they are more than a few years old or already showing signs of weeping, rather than reconnecting the new radiator to valves that were already on borrowed time. This is a small extra cost against the labour of opening the joint back up in six months when an old valve finally gives way. Balancing the system afterwards, using the lockshield valve on every radiator to set the correct flow, is what stops one newly replaced radiator from taking more than its share of hot water and leaving another room in the house running cooler than before. Moving a radiator to suit a new kitchen layout, an extension, or a knocked-through room is a common reason for replacement rather than a straightforward like-for-like swap. This might mean relocating a radiator to a different wall, removing it entirely where underfloor heating or a different heat source is planned for that space, or extending the pipe run to a room that previously had none. We check what the boiler and existing pipework can carry before agreeing to move a radiator, because adding length and extra bends to a circuit changes how it balances against the rest of the system, and cap off or reroute any redundant pipework properly rather than leaving a capped stub visible under new flooring or units. ### Residential and commercial properties We replace radiators in terraces, semis, flats and rental properties across Merseyside, and the practical constraints differ by property type. Solid-wall Victorian terraces often need heavier brackets fixed into original masonry for column radiators, while newer homes with plasterboard stud walls need the correct fixings specified before a heavy radiator goes up. On labour-only jobs we check the radiator you have bought is genuinely suitable for the wall it is going onto before we agree a fitting date. ### Variations of this service - Straightforward like-for-like swap Corroded or leaking panel radiator replaced with a new one of matching or better output, reusing the existing pipe centres and valve positions. - Panel to column or designer radiator Upgrading the style of a radiator while checking output carefully, since column and designer models do not always match a panel radiator's heat output size for size. - Heated towel rail installation Replacing a bathroom radiator with a heated towel rail sized to the room, with valve and pipework adjustments as needed. - Radiator moved for a kitchen or extension Relocating, removing or adding a radiator to suit a new layout, with pipework extended, rerouted or capped off properly. - Labour-only fitting Fitting a radiator you have already bought, with valves, brackets and pipework adjusted to suit, followed by a full system balance. ### Materials, parts and equipment - Panel, column and designer radiators from Worcester Bosch, Vaillant, Baxi and Heatline compatible ranges - Heated towel rails for bathrooms and en-suites - Thermostatic radiator valves and lockshield valves - Copper and press-fit pipework and full-bore isolation valves - Radiator brackets rated for the weight and size of column and designer models - Central heating inhibitor for re-dosing after every drain-down Questions ## Radiator Replacement & Supply and Fit: Frequently Asked Questions What is the difference between radiator replacement and radiator installation?Replacement swaps an existing radiator for a new one, usually in the same position, or relocates one to suit a new layout. A full radiator installation is typically part of a wider central heating project adding radiators to rooms that never had them, with pipework run from scratch. Can I supply my own radiator and just pay for fitting?Yes, we offer labour-only fitting. We will check the radiator's pipe centres, valve connections and weight are suitable for the wall before confirming a price, since not every radiator bought online arrives ready to connect to existing pipework without adjustment. Why is my radiator cold at the bottom but hot at the top?This is usually sludge or debris settled in the base of the radiator rather than trapped air, so bleeding will not fix it. Depending on how widespread the problem is across the system, the fix is either a full power flush or removing and flushing the individual radiator. Can you move a radiator for a new kitchen or extension?Yes. We check what the existing pipework and boiler can support before relocating, removing or extending a radiator circuit, and cap off or reroute any redundant pipework properly rather than leaving it hidden under new flooring. Will a designer radiator heat my room as well as my old panel radiator?Not necessarily. Column and designer radiators do not always match a panel radiator's output for the same wall space, so we check the heat requirement of the room against any replacement you are considering before fitting it. Do you replace the valves as well as the radiator?We recommend it where existing valves are aged or showing any sign of weeping, since reconnecting a new radiator to a failing valve just moves the leak risk rather than removing it. We will flag this before fitting rather than assuming you want them reused. Will replacing one radiator affect the rest of my heating system?It can, which is why we balance every radiator on the system after fitting, not just the new one, to make sure the change does not leave another room running cooler than before. Do you cover radiator replacement across Merseyside?Yes, across Liverpool, Knowsley, Halton and St Helens. We answer the phone seven days a week, 8:30am to 5:30pm, and can often arrange a replacement quickly once you have confirmed which radiator you need. Still not sure?
