Repair or Replace Your Boiler?
A boiler fault does not always mean you need a new system. Depending on the age, condition and type of problem, a boiler repair may still be the most practical and cost-effective option.
Signs that replacement may be worth considering include:
- Frequent breakdowns or repeated repair costs
- Heating or hot water that is no longer reliable
- The boiler repeatedly losing pressure
- Visible corrosion, leaks or damage
- Replacement parts becoming difficult to obtain
- An engineer advising that the boiler is unsafe or beyond economical repair
- Your current boiler no longer meeting your household’s heating or hot-water needs
Absolute Plumbing Limited can inspect the boiler, explain what has gone wrong and advise whether repair or replacement is the better option. If it can be repaired safely and economically, we can quote for the repair. If replacement makes more sense, we will recommend suitable boilers for your property and heating needs.
Which Type of Boiler Is Right for Your Home?
The right boiler depends on the size of your property, the number of bathrooms, your hot-water demand and the heating system already in place.
Our team will explain the advantages and limitations of each option, and recommend a new boiler installation that suits your property, heating needs and budget.
Combi Boilers
A combi boiler provides heating and hot water directly from one unit, without a separate hot-water cylinder. Combi boilers can be a good option for smaller homes or flats with one main bathroom and limited storage space.
Regular or Conventional Boilers
A regular boiler works with both a hot-water cylinder and a cold-water storage tank. It may be suitable for larger or older properties with traditional heating systems, especially where the existing pipework and water pressure are designed for this setup.
System Boilers
A system boiler works with a separate hot-water cylinder, allowing it to supply more than one outlet at a time. It often suits larger homes or households with higher hot-water demand, particularly where several bathrooms are used regularly.

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.

Two engineers from Absolute Plumbing Limited, Dave and Chris, assessed the heating system and removed the faulty pump.

Boiler Installer: Frequently Asked Questions
The cost depends on the boiler you choose and the work needed at the property. A direct replacement in the same location is usually simpler than changing the boiler type, moving it or upgrading pipework, the flue or controls.
Absolute Plumbing Limited will first discuss whether your current boiler still meets your heating and hot-water needs, then explain the suitable replacement options. The price of the boiler and any additional work will be included in a clear quotation before the installation begins.
Gas and plumbing labour is charged at £110 + VAT per hour in South West and Central London, but the total installation cost will depend on the full scope of the job.
A straightforward boiler replacement will usually take one day. More complex work may take two or more days, particularly if the boiler is being moved, the system type is changing or upgrades are needed to the pipework, flue or controls.
Absolute Plumbing Limited will assess the job beforehand and confirm the expected timescale in the quotation so you know how long the installation is likely to take.
The best boiler depends on your property size, number of bathrooms, hot-water demand and existing heating system.
- Combi boiler: Often suitable for smaller homes or flats with one main bathroom and lower to moderate hot-water demand.
- System boiler: Usually better for larger homes with more than one bathroom or households that regularly use several hot-water outlets at the same time.
- Regular or conventional boiler: Often suited to older or larger properties that already have a traditional heating system with a hot-water cylinder and cold-water storage tank.
Absolute Plumbing Limited will assess your current system, water pressure and heating needs before recommending the most suitable boiler type and output.
A standard boiler installation with Absolute Plumbing Limited includes removing and disposing of the old boiler, fitting and connecting the new boiler, completing the agreed pipework and flue work, and testing the system to make sure it is operating correctly.
We will also:
- Clean or flush the heating system where required
- Fit any agreed controls, filters or additional components
- Test and commission the new boiler
- Show you how to use the boiler and controls
- Register the manufacturer warranty where applicable
Your quotation will clearly set out everything included in the installation and identify any additional work needed at the property.
Yes. Once a qualifying boiler installation has been registered, you should receive a Building Regulations Compliance Certificate. Absolute Plumbing Limited’s Gas Safe registered installer will notify the installation on your behalf.
The certificate is normally posted to the property after the work has been registered. Keep it safe, as it confirms that the installation was notified under the Building Regulations and may be needed when you sell the property.
Yes. Absolute Plumbing Limited can install a new boiler in a different location, provided the proposed position is safe, suitable and meets the relevant installation requirements. The new location must allow for suitable flue and condensate connections, access for future servicing and any necessary gas, water and heating pipework.
Moving the boiler usually takes longer and costs more than replacing it in the same position because pipework, controls or the flue may need to be rerouted. Absolute Plumbing Limited will assess the proposed location, explain what work is required and include it in your quotation.
Yes. Absolute Plumbing Limited will remove your old boiler and dispose of it responsibly as part of the agreed replacement work. This is standard practice for a full boiler installation, and many UK installers include removal and disposal in their installation service.
The quotation will confirm what is included, particularly if the job also involves removing an old hot-water cylinder, storage tanks or other parts of the existing heating system.
Yes. Absolute Plumbing Limited uses Gas Safe registered engineers for boiler installations and other gas work. In the UK, anyone carrying out gas work must be registered and qualified for the specific type of appliance or work involved.
You can verify the business or individual engineer on the official Gas Safe Register using the company name or registration number.
Your new boiler will come with a manufacturer guarantee, but the length and cover will depend on the brand, model and installation package you choose. Many UK boiler guarantees cover manufacturing faults, including eligible parts and labour, for a set period. Some models offer longer cover when installed with approved components or by an accredited installer.
Absolute Plumbing Limited will confirm the available guarantee options before installation and explain who will register the boiler. Most manufacturers require registration soon after installation and an annual service by a Gas Safe registered engineer to keep the guarantee valid.
You should arrange for someone to be at the property when the boiler installation begins and when the work is completed. This allows the installer to gain access, confirm the agreed work and discuss any questions before starting.
You may not need to remain there throughout the entire installation, provided Absolute Plumbing Limited has permission to access the necessary areas. Someone should be available at the end so we can demonstrate the new boiler and controls, explain the paperwork and complete the handover.
Yes. Absolute Plumbing Limited installs boilers for commercial properties in London. We can assess the building’s heating and hot-water requirements, recommend a suitable system and provide a clear quotation for the installation.
Commercial boiler work will depend on the property, appliance type, output and existing system. We will confirm the scope, expected timescale and any access or upgrade requirements before work begins.
A new boiler should normally be serviced once a year by a Gas Safe registered engineer. Annual servicing helps check that the boiler is operating safely and efficiently, and it can identify developing faults before they become more serious.
Most manufacturers also require yearly servicing to keep the boiler guarantee valid. Keep the service record updated, as you may need it if you make a future guarantee claim.
