A new boiler is one of the bigger decisions you will make about your home, and it deserves more than a quick price over the phone. For more than 15 years we have been fitting boilers in homes across Barnet, Enfield, Haringey, Camden, Islington, Hackney, Waltham Forest, Bromley, Ealing, Redbridge and Harrow. Every job starts with a proper look at your property, your hot water habits and your existing pipework, so the boiler we recommend is the right size and type for the way you actually live.
Combi, system and regular boilers explained
Most homes suit one of three boiler types. The right one depends on how many bathrooms you have, how many people need hot water at once, your water pressure and how much space you have to spare.
Combi boilers
A combination boiler heats water directly from the mains as you need it, so there is no hot water cylinder and no tank in the loft. Combis are compact and work well in flats and smaller houses with one bathroom. They can struggle when two showers run at the same time, so they are not always the answer for larger households.
System boilers
A system boiler heats a sealed hot water cylinder, usually kept in an airing cupboard. Because hot water is stored, several taps and showers can run together. System boilers suit busy family homes with more than one bathroom and generally need no loft tanks.
Regular boilers
Also called conventional or heat-only boilers, these work with a hot water cylinder and a cold water tank in the loft. They are often the sensible choice in older London properties where the existing pipework was designed around a gravity-fed system, or where mains pressure is low.
Signs you may need a new boiler
Boilers rarely fail without warning. If you recognise several of these signs, it is worth getting an honest opinion before winter:
- Rising gas bills without any change in how you use your heating.
- Frequent breakdowns, or call-outs becoming a regular part of the year.
- Age – boilers over roughly 10 to 15 years old are usually far less efficient than modern condensing models.
- Leaks or corrosion around the casing or pipework.
- Parts that are hard to get, because the model has been discontinued.
- Uneven heating, with some rooms cold while others are warm.
Not every problem means replacement. Sometimes a repair to your existing boiler is the more sensible option, and we will tell you if that is the case.
Our installation process
We keep things clear and predictable from first call to final handover:
- Survey – we visit, check your current system, flue route, gas supply and water pressure, and talk through what you need.
- Recommendation – we explain which boiler type and size suits your home, and why.
- Quotation – you receive a fixed-price written quote, with no hidden extras added later.
- Installation – we remove the old boiler, fit the new one and protect your home while we work.
- Testing – we commission the boiler, check gas pressures, flue performance and controls.
- Handover – we show you how to use the boiler and controls and register the guarantee.
If you want the detail behind each stage, read our step-by-step guide to a boiler installation.
Benefits of professional installation
Gas work must legally be carried out by a Gas Safe registered engineer, but a good installation is about more than meeting the minimum. Correct sizing means the boiler is not oversized for your home and does not cycle on and off wastefully. Cleaning the system before the new boiler goes in protects the heat exchanger, which is why we often recommend a MagnaCleanse system clean alongside a new install.
A properly commissioned boiler is also what manufacturers expect before they honour their guarantee. On some models, guarantees of up to 10 years are available when the boiler is fitted and registered correctly and serviced every year. We register the boiler for you and notify the installation so you receive your compliance paperwork.
Finally, there is the simple matter of being treated well. We give honest, no-pressure advice, turn up when we say we will, and leave your home clean and tidy.
Boiler brands we install
We fit boilers from Worcester Bosch, Vaillant, Viessmann and Intergas. Each has its own strengths, and we are happy to explain the differences rather than push one name. You can compare them on our guide to the boiler brands we fit, or ask us during your survey.
Whichever brand you choose, looking after it matters. An annual boiler service keeps it running safely and keeps the manufacturer guarantee valid. When you are ready, get in touch for a free survey and a fixed-price quote.
