Overview
Heating faults are rarely just boiler faults
When a house will not heat properly, the boiler gets the blame first and is frequently innocent. Cold radiators, uneven heat, hot water that works while the radiators stay cold and rooms that never reach the thermostat setting are usually caused by circulation, valves, controls or water quality — components spread across the property rather than inside the appliance.
A heating repair therefore has to start with the system rather than the boiler. Flow and return temperatures, pump operation, motorised and thermostatic valve behaviour, wiring centre and control logic, radiator distribution and system water condition all get considered together, because fixing one in isolation frequently just moves the symptom somewhere else.
That is the practical advantage of one engineer covering boilers, full system installations and plumbing. Sam has 15 years on the tools and works on all of it, so a repair is not artificially confined to whichever part of the system falls inside somebody's specialism.
Who it is for
- Households where some radiators are hot and others stay cold
- Anyone whose heating comes on at the wrong times, or not at all, despite the boiler running
- Properties with banging, gurgling or noisy pumps and pipework
- Homes where hot water works fine but the heating does not, or vice versa
- Landlords who need a tenant's heating restored properly rather than temporarily
When it is needed
- Radiators cold at the bottom, or cold entirely, while others heat normally
- Thermostat or programmer no longer controls the system as it should
- Persistent noise from the pump, valves or pipework
- Heating that runs constantly, or short-cycles on and off
- Leaks from radiator valves, pipework joints or the pump
The cost of leaving it
What ignoring a heating fault leads to
Cold spots at the bottom of radiators mean sludge has settled inside them. That sludge does not stay put — it circulates, and everything it passes through pays for it. Pumps wear, valves stick, the boiler's heat exchanger silts up, and a fault that started as one lukewarm radiator turns into a system-wide circulation problem and, eventually, an appliance failure that the manufacturer will not cover.
Control faults cost money quietly. A programmer that no longer switches off, a thermostat sited badly or a motorised valve stuck open means the system heats when nobody asked it to. There is no dramatic symptom; there is simply a higher bill every month until somebody investigates.
Leaks are the escalation people regret most. A weeping radiator valve is a five-minute repair. The same leak left through a winter destroys floorboards, carpet and ceilings below, and constant automatic top-up feeds oxygen into the system and accelerates the corrosion that caused the leak in the first place.
There is also the seasonal trap: heating faults are tolerated through spring and autumn because the house is bearable, then become urgent in the first cold week, when every engineer in Hampshire already has a full diary.
Common mistakes
- Bleeding the same radiator repeatedly instead of asking why air keeps appearing
- Turning the thermostat up to compensate for a system that is not circulating properly
- Fitting a new pump when the actual restriction is sludge, so the new pump fails too
- Adding sealant to a leaking system instead of finding and repairing the leak
- Replacing the boiler to solve a fault that was never in the boiler
Our process
How a heating repair is carried out
System-wide diagnosis, then a repair that addresses the cause.
01
Symptom mapping
Which radiators are affected, when the fault appears, what the controls are doing and what has been done before. This narrows a whole-house symptom down to a circuit, a component or a water quality issue very quickly.
02
System diagnosis
Flow and return temperatures, pump operation and speed, motorised and thermostatic valve function, wiring centre and control operation, system pressure, and the physical condition of radiators and pipework are all checked.
03
Findings and price before work
You are told what has failed and why, and what it costs — £90 + VAT per hour plus parts for work that does not require a quote, or a fixed written quote for larger remedial work such as a powerflush or radiator replacement.
04
Repair and system correction
Pumps, motorised valves, thermostatic and lockshield valves, controls, radiators and leaking joints are repaired or replaced as needed, and the system is refilled, vented and re-dosed with inhibitor where it has been drained.
05
Balance, test and guarantee
Radiators are balanced so the house heats evenly, controls are proved through a full cycle, and the boiler is checked back into service. All workmanship carries our one-year guarantee, and if the underlying cause is water quality you get a straight recommendation rather than a repeat visit next season.
Benefits
What you get out of it
An evenly heated house, and the reason for the fault dealt with.
Lower running cost
Controls that work, valves that close and a system that circulates freely mean the boiler runs when it should and stops when it should.
Damage prevented
Leaks traced and repaired properly rather than topped up around, which protects floors, ceilings and the system's own water quality.
The cause identified, in writing
If the real problem is sludge, scale or an undersized emitter, you are told that plainly with the remedy and its cost, rather than being sold the same repair again next winter.
Transparent hourly rate
£90 + VAT per hour for work that does not require a quote, with the diagnosis explained before anything is started.
Guaranteed and insured
One-year workmanship guarantee, Gas Safe registered 593588, and £2 million public liability insurance behind every visit.
In detail
Common heating faults, and what causes them
The recurring failures we see across north Hampshire housing, and what each one actually means.
Cold at the bottom versus cold at the top
A radiator cold at the top and warm at the bottom has air in it, and bleeding it will fix it — though air that keeps returning points to a leak drawing in air, a failing automatic air vent, or pumping over on an older vented system.
A radiator cold at the bottom and warm at the top is the opposite problem: sludge has settled in the panel and water is only passing across the top. Bleeding achieves nothing there. It needs flushing, and if several radiators show it, the system as a whole needs a powerflush.
Pumps and circulation
A pump that is noisy, running hot or failing to develop head restricts the whole system. But pumps rarely fail for no reason — most die because they have been pushing debris-laden water for years. Replacing the pump without addressing the water simply resets the clock.
Setting the correct pump speed after replacement matters too. Too low and distant radiators starve; too high and the system becomes noisy and the boiler's return temperature climbs, pushing it out of condensing operation.
Valves: thermostatic, lockshield and motorised
Thermostatic radiator valves seize, usually in the closed position, and usually because they have been left untouched all summer. The pin can often be freed rather than replaced. Lockshield valves are the ones used to balance the system, and they are the reason a house heats evenly or does not.
Motorised valves — two-port and three-port — are the components that decide whether heat goes to radiators, the cylinder, or both. A failed motorised valve or actuator is the classic cause of hot water working while the heating does not, and it is frequently misdiagnosed as a boiler fault.
- Seized thermostatic radiator valves, often freeable rather than replaceable
- Lockshield valves set incorrectly, causing uneven heat distribution
- Two-port and three-port motorised valves and actuators
- Automatic bypass valves that have stuck open
- Automatic air vents that have failed and are drawing air in
Controls and wiring
Programmers, room thermostats, cylinder thermostats and the wiring centre form the logic of the system. A fault here produces behaviour that looks random: heating on at odd hours, hot water heating when it should not, or a system that will not respond to the thermostat at all.
Diagnosing controls is a matter of proving each element in turn rather than replacing the thermostat because it is the visible one. Poor thermostat siting — above a radiator, in a draught, or in the coldest room in the house — causes plenty of complaints that are not faults at all.
Leaks and system pressure
Leaks show up as recurring pressure loss on a sealed system. Common sources are radiator valve glands, compression joints on pipework that has been disturbed, the pump head gasket, the pressure relief valve discharging outside, and radiators corroded through from the inside.
Finding the source is far preferable to using a leak sealer. Sealants can clog the very components — pumps, valves, plate heat exchangers — that you least want blocked, and they make the next diagnosis harder.
Water quality: the root cause behind most of the above
Magnetite sludge forms wherever oxygen reaches steel radiators, and hard Hampshire water adds limescale to the mix. Together they restrict circulation, wear pumps, block valves and coat heat exchangers.
The remedy is a powerflush where the system is heavily contaminated, followed by inhibitor and a magnetic filter to keep it clean. That is the difference between a repair that lasts and a repair that recurs.

Questions
Heating repairs
answered straight
Anything not covered here, call 07825 758511 and ask. 8am–5pm, Monday to Friday, with out-of-hours emergency call-outs available.
How much do heating repairs cost?
Work that does not require a quote is charged at £90 + VAT per hour plus parts. Larger remedial work — a powerflush or several radiator replacements, for example — is given as a free written quote that is fixed once issued.
Why are some of my radiators cold?
Cold at the top means air, and bleeding will usually solve it. Cold at the bottom means sludge has settled in the radiator and it needs flushing. If several radiators are cold at the bottom, the system as a whole needs a powerflush rather than individual attention.
My hot water works but the heating does not — is the boiler broken?
Often not. On a system with a cylinder, that pattern usually points at the motorised valve, its actuator, the cylinder thermostat or the wiring centre. On a combi it is more likely the diverter valve. It is diagnosed by testing rather than assumed.
Can you fix a leaking radiator valve?
Yes. Leaking valve glands, failed thermostatic valves and corroded radiators are all repaired or replaced, and the system is refilled and re-dosed with inhibitor afterwards.
How long does a heating repair take?
Most diagnoses and common component replacements are completed in a single visit. Where parts have to be ordered, you are given the timescale on the day.
Do you offer emergency heating repairs?
Normal hours are 8am–5pm, Monday to Friday, and out-of-hours emergency call-outs are available for no heat, no hot water and leaks. Call 07825 758511.
Is my heating fault worth repairing, or should I replace the system?
If the pipework and radiators are sound and the fault is a component, repair every time. If the system is heavily corroded, undersized or has been extended piecemeal for decades, a full central heating installation is usually the better spend, and we will show you both figures.
Do you guarantee heating repairs?
Yes — a one-year workmanship guarantee on all work, and longer where the part fitted carries its own manufacturer warranty.
Will you re-balance the system after the repair?
Yes. Balancing is part of the job, not an extra, because a repair that leaves the house heating unevenly has not actually finished.
Which areas do you cover?
Basingstoke and north Hampshire, including Hook, Hartley Wintney, Tadley, Andover, Kingsclere, Overton, Micheldever and Aldermaston.
