FAQ:

How much does boiler installation near me typically cost?

The cost of a boiler installation depends on several factors, such as the size of your home, the type of boiler you need and the condition of your existing system. Every property is different, so there’s no single price that fits all. 

Before starting any job, a qualified installer will inspect your current setup to understand what’s required. Things like gas supply, flue position, pipe size and water pressure all affect the final cost and the kind of boiler that’s suitable for your home.

In most cases, we provide a detailed, fixed quote after the initial survey. That way, you know exactly what’s included the boiler, labour, controls, fittings and any additional work such as power flushing or thermostat upgrades.

It’s always best to avoid estimates given over the phone without a proper inspection. A site visit ensures accuracy and avoids hidden costs later. Professional installers will also recommend efficient models that match your household’s heating and hot water needs, helping you save energy in the long run.

A standard gas boiler installation in London usually takes one to two days, depending on the job’s complexity and the type of system being fitted. If it’s a like-for-like replacement for example, changing an old combi boiler for a new one in the same position most engineers can complete it within a single working day.

When converting from a system or regular boiler to a combi, it can take longer. This is because the old cylinder and water tanks need to be removed, and the pipework often needs adjusting. Installers may also need to run new flue or condensate lines, fit controls and carry out safety checks.

At the end of the installation, the engineer will test the system, balance the radiators and make sure the new boiler is working efficiently. They’ll also register the installation with Gas Safe and the manufacturer to activate your warranty.

While most homes only require a short installation time, larger properties or systems with underfloor heating may need additional work. A proper on-site assessment will always give you a clear timeline before any work starts.

Yes every boiler installer we use in London is Gas Safe registered. This certification is legally required for anyone working on gas appliances in the UK. It means they’ve been properly trained, tested and approved to work safely with gas boilers, pipework and flues.

When you hire a Gas Safe engineer, you can be confident that your boiler installation meets national safety standards. . Once the installation is complete, our engineers will issue a Gas Safe certificate confirming that the work meets regulations.

We always encourage customers to ask to see their engineer’s Gas Safe ID card before work begins. The card shows their photo, registration number and the types of gas work they’re qualified to do. You can also verify their details on the official Gas Safe Register website.

Choosing certified engineers not only keeps your home safe but also ensures your boiler warranty remains valid. Unregistered or unqualified installers risk voiding your warranty and could put your property at serious risk of gas leaks or carbon monoxide exposure.

Our boiler installation teams in London work with all major types of domestic boilers, including combi boilers, system boilers and regular (conventional) boilers. The right choice depends on your home size, water demand and existing setup.

Combi boilers are the most popular option for flats and smaller homes because they provide heating and hot water directly from the mains no tanks or cylinders needed. They’re compact, efficient and great for properties with limited space.

System boilers are better suited for medium to large homes with more than one bathroom. They work with a hot water cylinder, allowing multiple taps or showers to run at the same time without losing pressure.

Regular boilers, also known as heat-only boilers, are typically found in older properties with existing tanks and cylinders. They’re reliable for homes with traditional heating systems and larger hot water storage.

We install trusted brands like Worcester Bosch, Vaillant, Ideal, and Baxi. Before installation, our engineers assess your property to recommend the best system for your heating needs, water pressure and budget.
