CENTRAL HEATING & HOT WATER REPAIRS
Silver Saints repair central heating and hot water across London. No heat, no hot water, cold radiators, failed pumps and valves, and thermostats and timers that have stopped controlling anything.
Experienced engineers we know, not an app of anonymous bidders.
Gas, boiler and heating work is charged at this rate rather than our standard handyman rate.
Plus parts. No call-out fee. Saturday at the weekday rate. An annual gas boiler service is a fixed £100 plus VAT, and an unvented cylinder service the same.
What we fix
A heating system fails in a handful of places: the boiler, the circulation, the controls or the water in the pipes. We find which before anything is replaced.
No heating or no hot water
The whole system down, traced from the boiler outwards.
Cold radiators
One cold radiator or a whole floor of them, which are different problems.
Boiler not firing or locking out
Reset, then diagnosed, because a boiler that locks out twice will lock out again.
Low system pressure
Topped up and then investigated, since pressure that drops has somewhere to go.
A noisy or kettling boiler
Kettling, banging and gurgling, usually scale or poor circulation.
A frozen condensate pipe
The common winter lockout, thawed and lagged so it does not repeat.
Thermostat, timer or controls
Heating that runs constantly or not at all, which is often the controls, not the boiler.
Pump or motorised valve failure
The parts that move the water, and the usual cause of heating with no hot water.
Sludge and poor circulation
Identified honestly, because sludge needs a flush rather than a repair.
We work on gas and system boilers from Worcester Bosch, Vaillant, Ideal, Baxi and Glow-worm, radiators and TRVs, pumps, motorised and zone valves, room thermostats, programmers and timers, and central heating circuits and controls.
More specific? For a boiler fault code or breakdown see gas boiler repairs, for a landlord CP12 see gas safety certificates, for a badly sludged system see central heating power flush, for a cylinder see unvented hot water cylinder service and repairs, and for valve-only work see radiator and valve repairs.
What it costs
Labour at £98 plus VAT per hour, plus parts. Diagnosis is the first part of every heating job, because replacing a pump on a system whose real fault is a valve fixes nothing.
Gas Safe registered
All gas work is carried out by Gas Safe registered engineers, who work under their own registration, as required by the Gas Safety (Installation and Use) Regulations 1998.
That is the law for any gas work in a home or a rental property, not a matter of preference, and it is why gas work is not something our general handymen take on.
Anything on the gas side of a system goes to a Gas Safe engineer. Radiators, valves and the wet side of the heating can be done without one.
Where we cover
We cover all London boroughs plus the TW, KT, CR and BR postcode areas. London period conversions run old systems with cast-iron radiators and decades of sludge, while new-build flats run compact systems where one failed valve takes out the heating and the hot water together. Engineers cross central London by motorcycle and scooter, which means faster arrival and easier parking.
Landlords and letting agents
No heating or no hot water is the most urgent repair a tenant can report, especially in winter, and it is the one most likely to escalate.
We arrange access with your tenant or collect keys from your agent, so you do not need to attend, and we can carry out the annual gas safety check at the same visit.
Account invoicing and pre-approved spend limits are set out on our landlord services page.
Repair, flush or replace
Most heating faults are one component: a pump, a valve, a sensor or the controls.
Where the real problem is sludge in the system, a repair will not hold, and we will say that a power flush is what is needed rather than keep changing parts.
And where an old boiler is failing repeatedly and parts are getting hard to find, we will tell you plainly that replacement is better value than another repair.
Why Silver Saints
We are a managed service, not a bidding app: every Saint is a vetted professional we know personally, not a login on a marketplace.
Heating and hot water FAQs
How much does central heating repair cost in London?
Gas, boiler and heating work is charged at £98 plus VAT per hour, plus parts. Most diagnoses take about an hour.
Can you come out today for no heating in London?
Often yes. Silver Saints usually has same or next day slots for heating repairs in London, and every booking carries a one-hour arrival window.
Are your heating engineers Gas Safe registered?
Yes. All gas work is carried out by Gas Safe registered engineers working under their own registration, as the Gas Safety (Installation and Use) Regulations 1998 require.
I have heating but no hot water. Why?
Usually a diverter or motorised valve, or the cylinder controls. Silver Saints tests the valve and the controls before replacing anything.
Why does my boiler pressure keep dropping?
Pressure that drops has somewhere to go: a leak, a valve or a failed expansion vessel. Silver Saints tops it up and then finds out why.
My radiators are cold but the boiler is running. Why?
Often a pump, a valve or air and sludge in the system. Silver Saints checks circulation before condemning the boiler.
Are you a job-board app like the marketplaces?
We are not a job-board app. Unlike marketplaces that match your job to the cheapest available bidder, Silver Saints contracts its own team of experienced, vetted, multi-skilled tradespeople, people we know personally and work with directly. From booking to billing, you get one accountable service and a real relationship, not an anonymous login from a gig-economy pool.
Do you do the annual boiler service too?
Yes, at a fixed £100 plus VAT, and an unvented cylinder service is the same. Both can be booked alongside a repair visit.

Silver Saints repair central heating and hot water across London. We fix systems with no heating or no hot water, cold radiators, boilers not firing or locking out, low system pressure, noisy and kettling boilers, frozen condensate pipes, thermostat, timer and controls faults, failed pumps and motorised valves, and poor circulation from sludge. All gas work is carried out by Gas Safe registered engineers under their own registration, as the Gas Safety (Installation and Use) Regulations 1998 require. Labour is £98 plus VAT per hour, plus parts, and the annual gas boiler service is a fixed £100 plus VAT. Saturday is the weekday rate and there is no call-out fee.

No heating or no hot water?
Book online or call, and we'll sort it quickly with the Silver Service you deserve. Monday to Saturday, 8am to 5pm.
What's included in the service?
A Silver Saints central heating repair visit in London starts with diagnosis, not assumptions. Because the same symptom, such as no heating or no hot water, can come from the boiler, the cylinder, the pump, the valves or the controls, a GasSafe-registered engineer works through the system to find the actual cause before quoting the repair.
Diagnosis
The engineer establishes exactly what is wrong: firing the boiler and reading any fault codes, checking system pressure and circulation, testing the controls, motorised valves and pump, and checking radiators for trapped air or sludge. Where the fault is on the gas side, this includes the safety checks a GasSafe engineer must carry out.
Agreeing the repair
Once the fault is found, the engineer explains what needs doing and agrees the parts and the likely cost with you before starting. Where a manufacturer part is needed we recommend a like-for-like replacement so it is compatible with your system, and any larger work is quoted in full first.
Carrying out the repair
Most common heating and hot water repairs are completed on the visit, within the hour where possible: bleeding and balancing radiators, freeing or replacing a valve, replacing a pump, restoring lost pressure, or clearing a frozen condensate pipe. Where a part has to be ordered, we arrange a return visit and confirm the cost with you first.
On completion
The engineer tests that the repair has worked across the system, leaves the area clean and tidy, and the work is covered by our guarantee on the labour and parts we supply. All gas work is carried out by GasSafe-registered engineers.

Gas Safety Certificates in London
Silver Saints carry out landlord gas safety checks across London for a fixed £100 plus VAT. Gas Safe registered engineers, access arranged with your tenant, and the certificate emailed on completion.
Experienced engineers we know, not an app of anonymous bidders.
The £100 covers the visit and the first appliance. Extra appliances are added to that price.
No call-out fee. Saturday at the weekday rate. Certificate emailed on completion.
What we do
A gas safety check is an annual legal duty, not a nice-to-have, and it covers every gas appliance and flue in the property rather than just the boiler.
Landlord gas safety certificate
The annual CP12 the law requires, on every gas appliance and flue in the property.
An annual gas safety check
The same check for a homeowner who wants the peace of mind rather than the paperwork.
One appliance or several
A base price covers the visit and the first appliance, with extras added on.
Boiler, cooker, hob and fire
All gas appliances checked, not just the boiler, because the law covers all of them.
Combined check and service
The CP12 and the annual boiler service in one visit for £185 plus VAT.
Certificate for a new tenancy
Booked around your check-in date, so the record is in place before the tenant moves in.
Flue and ventilation checks
Part of every check, and the part that most often flags a problem.
Certificate emailed on completion
Sent the same day, so you have the record without waiting for the post.
Access arranged with the tenant
We contact them and arrange it, so you do not need to be there.
We check gas boilers, cookers, hobs and gas fires, gas meters, pipework and appliances, and the flues and ventilation serving them, using Gas Safe test equipment, and issue the CP12 Landlord Gas Safety Record.
Different job? For a boiler fault see gas boiler repairs, for the annual service on its own see gas boiler service, for heating and hot water faults see central heating repairs, and for the wider package see landlord services.
What it costs
A fixed price, not an hourly rate. The £100 plus VAT covers the visit and the first appliance, and extra appliances are added to it. Booking the certificate with the boiler service saves against doing both separately.
Prices exclude VAT. If an appliance fails the check, the repair is quoted separately at our £98 plus VAT hourly gas rate.
The legal duty
Landlords must arrange an annual gas safety check on every gas appliance and flue in the property, and give the tenant a copy of the record, under the Gas Safety (Installation and Use) Regulations 1998.
The record must go to an existing tenant within 28 days of the check, and to a new tenant before they move in.
Every check is carried out by a Gas Safe registered engineer working under their own registration, which the law requires for any gas work.
Where we cover
We cover all London boroughs plus the TW, KT, CR and BR postcode areas. London has one of the highest concentrations of rented homes in the country, so most of these checks are annual renewals we can diarise around your tenancy dates. Engineers cross central London by motorcycle and scooter, which means faster arrival and easier parking.
Landlords and letting agents
This is the one certificate you cannot let lapse, and the one most often chased at the last minute before a new tenancy.
We arrange access with your tenant directly, so you do not need to attend, and the certificate is emailed on completion rather than posted.
Booking the check with the boiler service in the same visit is £185 plus VAT, which is less than the two separately and means one access arrangement instead of two.
Account invoicing and pre-approved spend limits are set out on our landlord services page.
How the visit works
We contact your tenant and agree a slot with a one-hour arrival window, so nobody waits in all day.
The engineer tests every gas appliance in the property along with its flue and ventilation, which on most flats takes half an hour to an hour.
The certificate is emailed on completion. If anything fails, it is recorded, made safe where it needs to be, and the repair quoted separately.
Why Silver Saints
We are a managed service, not a bidding app: every Saint is a vetted professional we know personally, not a login on a marketplace.
Gas safety certificate FAQs
How much is a gas safety certificate in London?
A landlord gas safety certificate is £100 plus VAT, covering the visit and the first appliance. Additional appliances are added to that price.
Can I have the certificate and a boiler service together?
Yes. Silver Saints does both in one visit for £185 plus VAT, which is less than booking the certificate and the service separately.
Do landlords legally need a gas safety certificate?
Yes. Landlords must arrange an annual gas safety check on every gas appliance and flue and give the tenant a copy of the record, under the Gas Safety (Installation and Use) Regulations 1998.
How quickly can you do a CP12 in London?
Often the same or next day. Silver Saints arranges access with your tenant and emails the certificate on completion, so you do not need to attend.
Which appliances are checked?
Every gas appliance in the property: the boiler, and any cooker, hob or gas fire, plus the flues and ventilation that serve them.
What happens if an appliance fails the check?
It is recorded on the certificate and, where it is unsafe, made safe. Any repair is quoted separately at our £98 plus VAT hourly gas rate.
Are you a job-board app like the marketplaces?
We are not a job-board app. Unlike marketplaces that match your job to the cheapest available bidder, Silver Saints contracts its own team of experienced, vetted, multi-skilled tradespeople, people we know personally and work with directly. From booking to billing, you get one accountable service and a real relationship, not an anonymous login from a gig-economy pool.
Are your engineers Gas Safe registered?
Yes. Every check is carried out by a Gas Safe registered engineer working under their own registration, which the law requires for any gas work.
In summary
Silver Saints carry out landlord gas safety certificates and gas safety checks across London for a fixed £100 plus VAT, covering the visit and the first appliance, with extra appliances added to that price, or £185 plus VAT combined with the annual boiler service in one visit. We check boilers, cookers, hobs and gas fires along with their flues and ventilation, issue the CP12 Landlord Gas Safety Record, arrange access with your tenant so you do not need to attend, and email the certificate on completion.

Boiler & Heating Repairs in London
Silver Saints repair gas boilers across London. Boilers not firing, fault codes and lockouts, no hot water, low pressure, leaks and kettling, by Gas Safe registered engineers.
Experienced engineers we know, not an app of anonymous bidders.
Gas, boiler and heating work is charged at this rate rather than our standard handyman rate.
Plus parts. No call-out fee. Saturday at the weekday rate. An annual gas boiler service is a separate fixed £100 plus VAT.
What we fix
A modern boiler tells you it has failed but not why. A fault code narrows it down; the diagnosis is what tells you whether it is the sensor, the part it protects, or the system around it.
Boiler not firing or locking out
Reset and then diagnosed, because a repeat lockout is a fault, not a glitch.
A fault code on the display
Read as a starting point, then tested, rather than treated as the answer.
No hot water or no heating
Often the diverter valve on a combi, which is a repair rather than a replacement.
Low boiler pressure
Topped up and then investigated, since pressure that drops has somewhere to go.
A leaking boiler
Isolated and traced, whether it is a seal, a valve or the heat exchanger.
Pilot light or ignition faults
Ignition leads, electrodes and gas valves on older and newer boilers alike.
Cutting out intermittently
The hardest kind, tested until the fault shows itself rather than guessed at.
A noisy or kettling boiler
Kettling from scale or poor circulation, which is the system as much as the boiler.
A frozen condensate lockout
The common winter one, thawed and lagged so the same freeze does not repeat.
We work on combi, system and heat-only gas boilers from Worcester Bosch, Vaillant, Ideal, Baxi and Glow-worm, on PCBs, fans, pumps, diverter valves, pressure sensors, ignition and gas valves, and on flue and condensate runs.
Different job? If the boiler runs but the system does not heat see central heating and hot water repairs, for the annual service see gas boiler service, for a landlord CP12 see gas safety certificates, and if the boiler is past economic repair see boiler replacement.
What it costs
Labour at £98 plus VAT per hour, plus parts. Diagnosis comes first and is usually about an hour, because fitting a part on a guess is how a boiler gets two visits instead of one.
Gas Safe registered
All gas work is carried out by Gas Safe registered engineers, who work under their own registration, as required by the Gas Safety (Installation and Use) Regulations 1998.
That is the law for any gas work in a home or a rental property, not a matter of preference, and it is why gas work is not something our general handymen take on.
Anything on the gas side of a system goes to a Gas Safe engineer. Radiators, valves and the wet side of the heating can be done without one.
Where we cover
We cover all London boroughs plus the TW, KT, CR and BR postcode areas. London flats run compact combis in cupboards with awkward flue and condensate runs, and a condensate pipe on an outside wall is the reason so many boilers lock out in a cold snap. Engineers cross central London by motorcycle and scooter, which means faster arrival and easier parking.
Landlords and letting agents
A boiler breakdown is the most urgent thing a tenant can report, and the one most likely to become a complaint if it drags on.
We arrange access with your tenant or collect keys from your agent, so you do not need to attend, and the annual gas safety check can be done at the same visit.
Account invoicing and pre-approved spend limits are set out on our landlord services page.
Repair or replace, honestly
Most boiler faults are one component, and replacing it is far better value than a new boiler.
But on an old boiler where parts are scarce and expensive, and the same fault keeps returning, another repair is money after money.
We will tell you plainly which side of that line your boiler is on, and quote on the day rather than sell you a replacement you do not need.

Can you repair my boiler today in London?
Often yes. Silver Saints usually has same or next day slots for boiler repairs in London, and every booking carries a one-hour arrival window.

Yes. All gas work is carried out by Gas Safe registered engineers working under their own registration, as the Gas Safety (Installation and Use) Regulations 1998 require.
My boiler is showing a fault code. What does it mean?
The code narrows it down but does not name the cause. Silver Saints reads it and then tests, so the right part is replaced the first time.
Why does my boiler keep locking out?
A repeat lockout is a fault, not a glitch: often ignition, a sensor or a frozen condensate. Silver Saints diagnoses rather than just resetting it.
My combi gives heating but no hot water. Why?
Usually the diverter valve. Silver Saints tests it before replacing anything, and a diverter is a repair rather than a new boiler.
Are you a job-board app like the marketplaces?
We are not a job-board app. Unlike marketplaces that match your job to the cheapest available bidder, Silver Saints contracts its own team of experienced, vetted, multi-skilled tradespeople, people we know personally and work with directly.
