Heating Problems We Can Help With
Heating problems are not always easy to diagnose from the symptoms alone. You may know that the property is not warming properly, but not whether the fault sits with the boiler, radiators, controls or another part of the system.
We can help with:
- No heating
- No hot water
- A boiler that will not start or keeps cutting out
- Boiler error codes
- Radiators that remain cold
- Some rooms heating while others stay cold
- A heating system that keeps losing pressure
- Banging, bubbling or vibrating noises
- Leaking radiators, valves or heating pipes
- Heating that takes too long to warm the property
- Thermostat or heating-control problems
- Repeated faults elsewhere in the heating system
The visible symptom does not always reveal where the fault sits. Absolute Plumbing Limited will assess the relevant parts of the system before recommending a repair, replacement or further investigation.
Heating Engineer London: Our Services
Absolute Plumbing Limited provides heating repairs, installations and fault finding for homes and commercial properties across South West and Central London.
Boiler Installation, Repairs and Servicing
We install and replace boilers, diagnose faults and carry out repairs and routine servicing. We can also advise whether a repair remains practical or whether replacing the boiler would be the better long-term option.
Radiator Installation and Repairs
We install new radiators, replace existing units and repair problems such as leaks, cold spots, faulty valves and loose fittings. We can also advise whether the radiator itself needs attention or whether the problem may sit elsewhere in the heating system.
Heating-System Repairs and Fault Finding
We investigate pressure loss, poor circulation, uneven heating, unusual noises and faults that keep returning. We look beyond the most obvious symptom to identify what is causing the problem and what needs to be repaired.
Thermostats and Heating Controls
We diagnose faults with thermostats, timers and other heating controls that affect when or how your property warms up. Where needed, we can repair, replace or upgrade the relevant controls so the system responds properly.
Power Flushing and Circulation Problems
We assess heating systems where sludge or debris may be restricting the flow of hot water and causing cold spots or poor circulation. Not every cold radiator requires a power flush, so we will check the likely cause before recommending one.
A Real Example of Our Heating Repair Work
The Problem
Chris had been using Absolute Plumbing Limited for his annual boiler servicing. When the pump in his heating system needed replacing, he contacted Chris and Dave again to carry out the repair.
What We Did
Two engineers from Absolute Plumbing Limited, Dave and Chris, assessed the heating system and removed the faulty pump before installing the replacement.
The Result
The new pump was fitted and the heating system was working properly again. Chris was pleased with the team’s knowledge, punctuality and efficient service.
“Responsive, knowledgeable, efficient and on time. Chris & Dave look after my annual boiler service and a recent pump replacement too. Very happy to recommend.”

Frequently Asked Questions
A heating engineer installs, repairs, services and diagnoses problems with boilers, radiators and other parts of a heating system.
They can investigate issues such as no heating, no hot water, pressure loss, cold radiators, faulty controls, poor circulation and unusual noises. Where the work involves a gas boiler or another gas appliance, the engineer must be appropriately Gas Safe registered.
A plumber mainly works on water, pipework, taps, toilets and drainage, while a heating engineer specialises in boilers, radiators and central-heating systems.
There is some overlap between the two trades, particularly with radiators and heating pipework. However, not every plumber is qualified to work on a gas boiler. Any work involving gas appliances or gas fittings must be carried out by an engineer who is Gas Safe registered and qualified for that specific type of work.
Absolute Plumbing Limited provides both plumbing and heating services, so the team can determine which expertise is needed for the problem you are experiencing.
You should call a heating engineer when your heating or hot-water system is not working properly, the same fault keeps returning or you are unsure whether it is safe to keep using the system.
Common reasons to arrange a visit include:
- No heating or hot water
- A boiler that will not start or repeatedly cuts out
- Boiler error codes that return after a reset
- System pressure that keeps dropping
- Radiators that stay cold after bleeding
- Some rooms heating while others remain cold
- Leaking radiators, valves or heating pipes
- Banging, bubbling or vibrating noises
- Faulty thermostats, timers or heating controls
- Heating that takes unusually long to warm the property
A one-off issue may sometimes have a simple cause, but repeated pressure loss, recurring error codes or ongoing circulation problems should be professionally investigated rather than repeatedly reset or topped up.
Where the problem involves a gas boiler, the work must be carried out by an appropriately Gas Safe registered engineer.
Look for a heating engineer whose qualifications, relevant experience, reviews and pricing can all be checked before you book.
For gas boiler work, verify the business on the Gas Safe Register and ask to see the individual engineer’s Gas Safe ID card. The card also shows which categories of gas work that engineer is qualified to carry out.
Read recent reviews across more than one platform, but do not rely only on the overall rating. Look for reviews that mention the same service you need, such as boiler repairs, radiator work or heating-system fault finding, and pay attention to comments about punctuality, clear explanations, tidy workmanship and whether the final cost matched what was agreed.
It is also sensible to check whether the company has been independently vetted and whether it explains its pricing clearly. Ask what the call-out or hourly rate covers, whether VAT and materials are additional, and whether you will be consulted before any extra work is carried out. Consumer guidance also recommends verifying credentials rather than taking claims at face value and getting a clear breakdown of costs.
Absolute Plumbing Limited is Gas Safe registered, Checkatrade approved and rated 5.0 on Google, with reviews covering plumbing, boiler, radiator and heating work.
Go to the Gas Safe Register’s “Find an Engineer or Check the Register” page and search using the business name, location or Gas Safe registration number.
Once you find the business, check that its registration is current and that it is qualified for the type of gas work you need. You should also ask the individual engineer to show you their Gas Safe ID card when they arrive, as this confirms their identity and lists the categories of gas work they are qualified to carry out.
Absolute Plumbing Limited charges £110 + VAT per hour for heating work, with the final cost depending on the fault, the time required and whether any replacement parts or additional materials are needed.
A straightforward diagnosis or repair may be completed within the first hour, while recurring pressure loss, circulation problems, boiler faults or work involving several parts of the heating system may take longer. Parts and materials are charged separately where required.
The engineer will explain what has been found and discuss any additional work and costs with you before proceeding.
A fair quotation should clearly explain the work being proposed, the labour rate, whether VAT is included and which parts or materials will be charged separately.
Make sure you understand whether you have received a fixed quotation or an estimate based on the expected time required. The document should also explain what could cause the final price to increase and confirm that additional work will not be carried out without your agreement. For larger jobs, comparing written quotations from several suitably qualified engineers can help you judge whether the price and scope are reasonable.
Do not compare the final figures alone. One quotation may include parts, system testing, removal of old equipment or other work that another excludes, so check that you are comparing the same scope.

Yes. Absolute Plumbing Limited will explain what has been found and confirm the proposed repair and cost before carrying out any additional work.
Heating work is charged at £110 + VAT per hour, with parts and materials charged separately where required. If the engineer identifies further work during the job, this will be discussed with you before proceeding.
A trustworthy heating engineer should assess the fault and explain whether a repair is practical before recommending replacement.
The right option depends on factors such as the age and condition of the boiler, radiator or heating component, the cause of the fault, the availability and cost of replacement parts, and whether the same problem is likely to return. A repair may make sense when the fault is isolated and the rest of the system is in good condition, while replacement may be more reasonable if the equipment is badly corroded, repeatedly breaking down, unsafe or uneconomical to repair.
Ask the engineer to explain what has failed, what the repair would involve, how much it is expected to cost and why replacement is being suggested. For a major or expensive replacement, you may also choose to obtain another written quotation before deciding. UK consumer guidance recommends using a Gas Safe registered engineer for gas boiler work and checking the cost of the visit and proposed work before proceeding.
Absolute Plumbing Limited assesses the problem first and will not automatically recommend replacing a boiler, radiator or heating component where a suitable repair is available.
Absolute Plumbing Limited will take the precautions needed to protect your floors, walls, furniture and belongings while the work is carried out.
Depending on the job, this may include moving vulnerable items out of the work area, using protective coverings, keeping tools and materials contained, and taking particular care when draining radiators, lifting floorboards or accessing pipework. Professional heating companies commonly use measures such as dust sheets and overshoes to help keep customers’ homes clean and protected.
Our team takes pride in careful workmanship and will clean the work area, remove waste and leave your home neat and tidy once the job is complete. Where heating work affects walls, flooring or finishes, we will explain what is required and help ensure the area is left in a better condition than we found it.

If you smell gas, call the National Gas Emergency Service immediately on 0800 111 999. The helpline is free and available 24 hours a day.
While waiting for advice or assistance:
- Open doors and windows to ventilate the property.
- Turn off the gas supply at the meter, provided you can do so safely.
- Extinguish cigarettes and any other naked flames.
- Do not switch lights or electrical appliances on or off.
- Do not use anything that could create a spark.
- Leave the property if the smell is strong or you feel unsafe, and make the call from outside.
Do not wait for a routine heating-engineer appointment or attempt to find the leak yourself. Follow the emergency service’s instructions and only allow an appropriately Gas Safe registered engineer to carry out any necessary gas work.
