Placing Orders

Our online quoting system will give you a fixed and bespoke quotation for most typical domestic boiler installations. All that is required is a postcode and answers to some basic questions about your property to help decide what boiler is suitable for your home. However, feel free to call or email us and we’re happy to discuss more specific requirements, or answer any questions you have. If you like, we’ll even come and see you at home
All boilers are not equal. Most online boiler companies will only quote simple combi boiler replacements as this makes it easier for them to quote, but they sometimes overestimate the price to cover their “unexpected costs”. At Simply Fit we are heating specialists with over 20 years experience so our online quoting system can offer bespoke quotations for most combi boilers, system boilers and regular (heat only) boilers based on the questions asked in our online quoting system. Should your property fall outside of the parameters for an online quote we’ll let you know straight away and ask you to call us to book a home survey. We’ll then come to you free of charge to work out a price for your property, providing options based on price, efficiency and required use
For a new build property and/or full refurbishment we would recommend booking a home survey. We’ll come out to meet you to go through everything required, and will recommend the best solution for your heating and hot water requirements. Don’t just be talked into a combi because uncle bill has one and he says they are great, there may be a better, more efficient solution for your home


About Our Boilers

A combination or ‘combi’ boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in your roof space.
They are also very cost-effective and energy-efficient, as water is heated instantly rather than being heated and then stored in a cylinder. An added benefit is that hot water is delivered at mains pressure, which means that you could get a powerful shower without the need for a separate pump
Heat Only boilers (sometimes known as regular or conventional boilers) are typically found in homes that already have a traditional heating and hot water system with a separate hot water cylinder. The systems are normally called 'Y' Plan or 'S' plan systems. These boilers also need a cold water storage tank in the loft to feed the hot water cylinder as well as a tank that maintains the water level of the central heating system.
A regular boiler is sometimes still the best option for replacing an existing boiler if the property has an exceptionally old radiator system, as it might not be able to cope with the higher water pressure that is delivered by system or combi boilers, if you're in any doubt what to go for jut give us a ring and we'll talk through your options. There's always a way to fit a combi but its best to check with us first as you may need a survey to check.
System boilers also require a cylinder for storing hot water however are typically mains fed, with a pressurised heating system also. Some of the heating components such as the pump and diverter valves are built into the boiler itself.
Your can normally expect very good hot water flow rates and system boilers are actually preferred in larger homes with a bigger hot water consumption by using a cylinder that heats up much more quickly. These boilers are also compatible with solar water heating systems, by using a twin coil cylinder which deliver environmental benefits as well as lower energy bills.
A combi boiler is a self contained unit that historically, used to have lots of internal parts. They got quite a bad reputation years ago for being unreliable, but this is definitely not the case now! They have much less moving parts and are extremely reliable if fitted correctly. Millions of homes in the UK are heated using combi boilers and it has to be said they were a genius invention. We of course can advise if a combi is suitable for your property based on the size and output of your home, just give us a call
Yes we do. We know in some cases a standard combi boiler just won't cut the mustard for your hot water requirements, that's why we offer storage combi's with a built in hot water tank. These units are not that much bigger than a normal combi boiler but can deliver hot water at approx 18-20 litres a minute, which is nearly double the rate of a normal combi, feel free to give us a call if you want to find out more
Yes Absolutely! Generally, traditional boilers waste huge amounts of energy through the hot flue gasses, but modern boilers recycle the heat lost from the gasses so you may get away with a slightly smaller output boiler in your home that is much more efficient. Think of it like this; with your old boiler if you spend £100 in energy you may only get £60-£70 back in heat, with a new boiler fitted and sized correctly you spend £100 and get around £95 back in heat. Efficiency is found in correct radiator sizing, range rating and effective commissioning by a well trained engineer
The gas Industry is such that boilers typically get incorrectly specified by inexperienced companies. This is not the case at Simply Fit. Before your order is confirmed we’ll double check your requirements to make sure your boiler is sized correctly for your home to ensure the best performance and efficiency. For example; If you’ve decided to have a combi boiler fitted and require better hot water flow rates, you might want to increase the kW rating of your boiler to suit, but its not just a matter of installing a larger boiler. Our engineers will range rate your boiler on commissioning after installing it to perfectly suit the exact output required on heating so you get the best of both worlds, optimising output whilst maintaining efficiency. If you are unsure of what output size you require, go through our online quoting system, or book a home survey if you would like a custom configuration
To validate your boiler warranty you must get your boiler serviced properly every year. When we say properly we mean according to manufacturer's instructions, which is a lot more than a simple flue gas analysis (which takes literally 10 minutes). Thankfully at Simply Fit we service boilers properly are manufacturer approved and can take care of this for you just give us a call or book online
At simply fit we take our customers' safety very seriously and we recommend that you get your boiler serviced at least annually to keep your boiler in great shape and to support your warranty. We can do that for you through our aftercare & servicing page
