Emergency Boiler and Heating Repairs London

When winter closes in the last thing you need is your central heating breaking down. During the winter a warm cozy house throughout and hot water on demand is all you want, right? Unfortunately, boiler breakdowns occur when you least expect them. When they do, you want a professional company to swiftly repair it with the minimum of downtime? The issue could be anything from the simplest to the more complex of breakdowns. Either way, you want a professional gas safe registered engineer to diagnose the fault and quickly fix it.

Electric Boiler Repairs

Electric boilers do not create dangerous emissions such as carbon monoxide (gas boilers do) which can be fatal! Both works on the same basic principle except electricity obviate the need for oil, gas, and a flame to heat the water in the system. Electric boilers are compact and do not require a separate flue, chimney, or need to be fitted to an outlet wall, which gives greater flexibility in terms of where the boiler is located. If you experience any problems with your electric boiler, service team can help 24/7.

Gas Boiler Repair

Gas boilers are to be phased out over the next decade (or so) according to Government reports. This is so the UK can decrease its dependence on fossil fuels and improve the eco standard of housing and the environment. So, change is afoot but not just yet. Besides, there’s still plenty of life in your gas boiler, so no need to concern yourself just yet. However, in the years ahead you will need to make plans for an alternative heat source for your home. In the meantime, let’s focus on the here and now and repairs to your boiler.

  More About Boiler Repair

    Combi boiler repair

    A combi boiler is a combination of a water heater and central heating system. When you turn on the hot water tap, hot water is instant. Which means you don’t have to heat the water and store it in a water cylinder. In the event of a combi breakdown though, there isn’t a cylinder to store hot water in, so you will be without until the boiler is fixed.

    Boiler repair or replacement

    It depends on many factors whether you should replace or repair your existing boiler in the event of a breakdown. If the boiler is under warranty and a repair/replacement option is available then go for the best option. With boilers that have been in service for 10-15 years or more there could be a problem with parts becoming obsolete. Maybe, the part/s can be sourced, but probably at a cost! If the repair cost is close to the cost of a new boiler, then it makes economic sense to replace it.

    Repairs to common boiler problems


    There could be various reasons for a leaking boiler. Sometimes it can be a worn seal on the various connection points in the boiler. You may notice water dripping from beneath the boiler, which usually suggests a loose connection or a crossed thread in the brass coupling. It could be due to corrosion or the result of poor workmanship.

    Low pressure

    The usual boiler pressure in a fully charged boiler should be between 1.4 and 2 bars. If the water pressure is lower 1.4 bars and constantly drops after you have topped it up, it could suggest a faulty expansion vessel or a leak somewhere in the pipework that needs fixing immediately.

    Insufficient heating

    Could be caused by a range of issues. However, the common one in our experience is the build-up of sludge in radiators. This produces cold spots and poor circulation. The boiler has to work at its maximum in an attempt to reach the temperature set on the thermostat, which won’t happen, up go the energy bills! Cold spots or trapped air in the radiators is best handled by a professional heating engineer.

    No heating

    If the heating doesn’t turn on it could be a fuse has tripped or the boilers’ thermostat is faulty or not turned up high enough (not really an issue). However, the problem can also be more complex, like an issue with the PCB/valve etc

    Hot water but no heating

    If you are receiving hot water without heating (vice versa) or during the summer months, when the heating is off, you notice a radiator/s closest to the boiler getting warm/hot. This is usually related to a faulty diverter valve. Time to replace it.

    Boiler noises

    If your boiler is rattling, knocking, popping and bubbling it could be limescale, debris or sludge build-up inside the boiler. If your boiler is ‘kettling’ introduce some FERNOX Boiler Noise Silencer available from any decent plumbing merchant or an online plumbing supplier. A full dose of this will silence those strange popping and bubbling noises. The installation of a limescale reducer will prevent limescale building in the pipes and hot water storage tank (which you won’t have if you’ve a combi boiler).

    Faulty pilot light

    Failing thermocouple, broken seal, or a faulty gas valve can be the cause of a faulty pilot light. During your annual boiler service the pilot light will checked.

    The boiler regularly shuts off

    If your boiler keeps shutting off it could be an intermittent fault, which are not always easy to diagnose. If the fan is not working as it should the circuit board stops the boiler from working. The fan starts up before the boiler and generates a draught that forces harmful gases up through the flue to the outside. An Air Pressure Switch determines if the boiler is safe to start and carry on working. If you experience the above and to avoid further complications, contact a professional gas engineer as soon as possible.

    Frequently Asked Question

    Q: Do I need to call a professional to fix a hot water heater?

    A: Yes, that’s why serviceteam is here to take away the worry and risk from a keen DIYer taking a ‘punt’ with this type of repair. If you do take a ‘punt’ and have a go’ yourself, you will be coming into contact with water and electricity and you risk becoming electricity’s path to ground - it’s dangerous! DIY Lives Matter! To be honest, it’s not worth the risk. So, if in doubt, contact serviceteam Ltd. on 020 3811 0705 and book a visit for a professional tradesperson to diagnose the fault and repair it.

    Q: How long does a hot water tank remain warm (non-combi boiler)?

    A: Well, it depends on the type and quality of the cylinder installed and the insulation around it (foam lagged/cylinder jacket etc). However, the average water cylinder will remain hot for several hours. If a shower/bath is taken, then of course the hot water reduces as it’s replaced with cold water. At least you have a temporary hot water backup for the odd shower. Unfortunately, with a combi boiler you will not have the luxury of a cylinder full of hot water as backup (it was removed when the combi was installed) That’s when you have to move quickly to avoid any inconvenience by calling serviceteam Ltd. and get your repair visit booked.

    Q: Do electric boilers require servicing?

    A: Unlike a conventional gas boiler, electrical boilers have fewer mechanical parts, but it is still recommended to have your boiler serviced at least annually even more so if a system filter or inline scale reducer has not been installed.

    Q: Are electric Boilers more efficient than gas boiler?

    A: Well, electricity is more expensive than gas, that's for sure but you may very well save on servicing and repairs. Before deciding to change to an electric boiler, you will need to check the maximum load that your circuit board can safely manage; otherwise it will trip out regularly. It's possible to have an 80 or 100 amp fuse fitted into UK homes, but first, you must consult a qualified electrical engineer who will give advice before you invest in an electric boiler.

    Q: Are electric Boilers as good as gas boilers?

    A: Well, it’s up to you to decide which one’s better for you. Electric boilers are more compact, more energy-efficient, and comparatively cheaper to install. A Government initiative is looking at phasing out all gas boilers in domestic properties around 2025 to meet emission targets. Running costs will be slightly higher with an electric boiler.

    Q: Gas or an electric boiler which one is more efficient?

    A: When it comes to efficiency, an electric boiler is more efficient and cheaper to install than a gas boiler, but a unit of electricity (kWh) is more costly then a unit of gas, which means higher energy bills!

    Q: Is it okay to leave the boiler on?

    A: No, especially if you’re not at home. If you are away from home and have a remote connection to your system via your mobile phone you can schedule the heating to fire up for a limited time, if freezing weather conditions are forecast. This might be an option worth exploring with serviceteam Ltd?

Serviceteam completes so many jobs during a year that we can often provide you with a fixed price for the works without attending Other jobs require am enquiry to be raised, so we can compile a quotation. Any photos provided will help us to assess requirements. If your project is large or complex, we will assign one of our qualified engineers to visit and prepare a detailed quotation. Alternatively, you can select serviceteam’s Pay by Time option, certainly if you have an emergency or a “to do” list made up of one or several minor jobs. When on site our engineer will appraise the works required and give an indication of how long the works are expected to take. If we are unable to complete the works within the first visit due to the need for extra time or materials, then we will provide you with a fixed price quotation for the extended works for consideration and authorization before proceeding.
Enquiries can be logged through our website, email, WhatsApp or by calling 020 3538 7067.

What happens next?
When booking online the details of your job, including your preferred time slot/s will be sent to our scheduling department where within one working hour, scheduling will assign the appropriately qualified engineer to your job.

If we are unable to accommodate your job at the time requested, due to high demands on our resources, we will be in touch with alternative dates.

How do we charge?
At the point of booking your service we will log your preferred payment details card number etc. Payment will not be taken from your credit/debit card until the works have been completed, usually within 24 hours. Please note credit card transactions are limited to £150.00. maximum. A copy of your paid invoice and a job-sheet will be emailed to you when payment has been approved. Our dedicated Operations Team, based in London, are on call to discuss any current or future jobs as well as managing your project through to completion.
