Water damage from a slow leak
A radiator valve that weeps rather than drips can go unnoticed for months, staining floors, skirting and ceilings below before anyone realises it is more than condensation.

What radiator installation and repair covers
Radiators are the part of the heating system you actually feel, which is exactly why faults here are noticed fast, a cold bedroom, a valve dripping onto the floor, a radiator that takes an age to warm up. This service covers both replacing and adding radiators, and repairing the valves, pipework connections and radiator bodies themselves when something goes wrong.
On the installation side, the most common jobs are upgrading an old single panel radiator to a double panel or double convector to noticeably increase heat output in an undersized room, adding radiators to an extension or loft conversion, and replacing radiators as part of a bathroom or kitchen refurbishment where the old radiator no longer suits the space. I size every replacement or new radiator against the room's actual heat loss rather than matching the output of whatever was there before, which is often the reason a room felt cold in the first place.
On the repair side, leaking valves, corroded radiator bodies, seized thermostatic radiator valves and radiators that will not bleed properly are the calls I get most often. Some of these are quick fixes on the day; others, a radiator that has corroded through, for example, need replacing rather than repairing, and I will always tell you which applies before doing any work.
Who it is for
Homeowners in Epsom, Reigate, Banstead, Cobham and South West London upgrading undersized radiators, adding heating to a new room, or dealing with a leaking, cold or faulty radiator that needs fixing or replacing.
When it is needed
When a radiator is leaking from a valve or joint, will not heat up despite bleeding, is visibly corroded or rusting through, or when a room consistently feels colder than the rest of the house because the radiator was never sized correctly for it.
Why a professional matters
Radiator work involves draining and refilling part of the heating system, correct isolation of valves, and, for gas-fired systems, attention to how the change affects overall system balance and boiler performance, all of which benefit from proper diagnosis rather than a straight swap.
What happens when radiator faults are left
A dripping valve or a radiator that never quite gets warm rarely feels urgent, which is exactly why these faults are often left until they cause more disruption than the original problem.
Corrosion getting worse
A radiator body that has started to corrode will not repair itself, and a small pinhole leak today is a split radiator later, usually at the least convenient moment.
Cold rooms you stop noticing
It is easy to adjust to a cold room by using a portable heater or simply accepting it, but an undersized or faulty radiator is usually a straightforward fix rather than something to live with indefinitely.
System-wide knock-on effects
A stuck valve or a radiator that will not balance correctly can affect circulation to other radiators on the same circuit, so one faulty radiator can be part of why a whole floor heats unevenly.
Common mistakes I get called out to fix
- Ignoring a slowly weeping valve because it is only a small drip, until it damages flooring beneath.
- Replacing a radiator like-for-like without checking whether the room actually needs a higher output.
- Repeatedly bleeding a radiator that will not hold air out, rather than investigating a failing valve or vent.
- Painting over early corrosion on a radiator body instead of addressing it before it becomes a leak.
- Fitting a new radiator without isolating and draining the system correctly, risking airlocks or leaks elsewhere.
My radiator installation and repair process
- Step 1
Assess & quote
For new or replacement radiators I check room size and heat loss to recommend the right output; for repairs I diagnose the fault on-site. New installation work is quoted as a fixed price; repairs are quoted hourly with no call-out fee.
- Step 2
Isolate & drain
The affected part of the system is isolated and drained correctly, minimising disruption to the rest of the heating circuit.
- Step 3
Fit, repair or replace
New radiators are hung level and connected with the correct valves; repairs address the actual fault, whether that is a valve, a joint or the radiator body itself.
- Step 4
Refill, bleed & balance
The system is refilled, radiators bled properly, and flow balanced so heat is distributed evenly across the circuit rather than favouring whichever radiator is nearest the boiler.
- Step 5
Test & guarantee
The radiator is tested for leaks and even heat output before I finish, backed by 1 year on my workmanship and 1 year on parts and materials supplied.
What you get from professional radiator work
Correctly sized heat output
New and replacement radiators are specified against the room's actual heat loss, not just matched to what was there before.
No call-out fee for repairs
You are never charged simply for me attending to assess a leak or a cold radiator.
Transparent pricing
Reactive repairs are priced hourly with the rate agreed upfront; larger installation jobs are quoted as a fixed price before work starts.
Leaks found and stopped properly
Valve, joint and radiator body leaks are diagnosed and repaired or replaced rather than temporarily tightened and left to recur.
Even heat across the system
Balancing the circuit after new or repaired radiators go in means heat is distributed properly rather than concentrated near the boiler.
Guaranteed work
1 year on my workmanship and 1 year on materials and parts supplied, including new radiators and valves.
Radiator installation and repair detail: types, faults and situations
Radiator work covers a wide range, from a single valve repair to a full room-by-room upgrade. Here is how I approach the situations I see most often across Surrey and South West London.
Radiator installation and upgrades
Upgrading from a single panel to a double panel or double convector radiator is one of the most cost-effective ways to fix a persistently cold room, since it significantly increases heat output for the same wall space. New radiators for extensions or converted lofts are sized against the specific heat loss of the new room rather than assumed from a nearby existing radiator.
- Single to double panel or double convector upgrades for undersized rooms
- New radiators for extensions, loft conversions and converted garages
- Radiator replacement as part of bathroom or kitchen refurbishments
- Column and designer radiator installation where style matters alongside output
- Low surface temperature radiators where safety is a consideration
Common radiator faults and repairs
Leaking valves are the most frequent call, usually from a worn valve spindle or gland rather than the radiator itself, and are typically repairable without replacing the whole radiator. Radiators that will not heat despite bleeding often point to a stuck or closed valve, a lockshield that has never been set correctly, or sludge restricting flow through the radiator body.
- Leaking thermostatic radiator valve (TRV) and lockshield valve repair or replacement
- Diagnosing radiators that will not bleed or hold heat
- Radiator body leak assessment, repair versus replacement
- Pipework joint leaks at radiator connections
- Valve seizure and TRV head replacement
Balancing and system-wide effects
Adding, replacing or repairing a radiator changes how the whole circuit balances, particularly on older systems. I check and adjust lockshield valves across affected radiators so the change does not leave other rooms starved of flow.
Domestic and small commercial radiator work
Most radiator installation and repair work is residential, houses and flats across Epsom, Reigate, Banstead, Cobham, Walton-on-Thames, Dorking, Worcester Park and South West London, including landlord instructions for tenant-reported faults.
Small commercial premises with a wet heating system are covered where the work sits within the scope of my Gas Safe registration.
Radiator Installation & Repair — your questions answered
How much does it cost to replace a radiator?
New radiator installations are quoted as a fixed price based on the radiator size, valve type and any pipework changes needed, agreed upfront and always with a free quote. Simple repairs, like a leaking valve, are charged at £90 + VAT for the first hour with no call-out fee.
How long does it take to fit a new radiator?
A straightforward like-for-like radiator swap usually takes a couple of hours. Adding a radiator to a room that has never had one, or upgrading pipework to support a larger radiator, can take longer, which I confirm at quote stage.
My radiator is leaking from the valve, is that urgent?
A dripping or weeping valve is worth attending to promptly since it can damage flooring if left, though it is rarely a genuine emergency unless it is leaking heavily. I can usually get to it within 24 hours as a standard call-out, sooner if it is significant.
Why is my radiator cold even after bleeding it?
This usually points to a stuck or closed valve, a lockshield that was never set correctly, or sludge restricting flow through the radiator. I diagnose the actual cause on-site rather than assuming bleeding alone will fix it.
Should I upgrade to a bigger radiator instead of just replacing it?
If the room has always felt cold, quite possibly. I check the room's heat loss against the existing radiator's output and will tell you honestly whether a like-for-like replacement is enough or whether upgrading to a double panel or double convector would actually solve the problem.
Can you add a radiator to a room that has never had one?
Yes, provided pipework can be run to it from the existing circuit: common with extensions, converted lofts and garages. I check the existing system has capacity before quoting so the new radiator does not starve others of heat.
What guarantee do you offer on radiator work?
1 year on my workmanship and 1 year on materials and parts supplied, including new radiators, valves and fittings.
How long should a new radiator last?
A good quality radiator on a system with clean water and correct inhibitor dosing should last many years without issue. Corrosion and sludge are what shorten radiator life, so I check system water quality as part of any installation.
Do you repair designer or column radiators as well as standard panel radiators?
Yes, the diagnosis and valve repair process is the same regardless of radiator style, though parts availability can vary for older or unusual designer models, which I will check before quoting.
Which areas do you cover for radiator installation and repair?
Epsom, Reigate, Banstead, Cobham, Walton-on-Thames, Dorking, Worcester Park, the wider Surrey area and South West London, based from Reigate.
