Is there a comparison site for replacement combi boilers? Look no further!
January 13, 2022
Are you thinking about getting a brand new combi boiler for your home to keep it nice and warm in winter? Gas boilers are one of the most significant investments that you can make when you’re improving your home. If you’ve never had new one installed before or it’s been a long time since you last replaced your gas boiler, what is it that you need to know to make the right choice for your household?
There are different types of gas boiler such as the
When budgeting for your replacement combi boiler, here’s a general range of prices to give you a good idea of just how much you’ll need to save up.
|On your quote||Range of prices|
|The cost of your boiler||£625-£6,190|
|Boiler installation cost||£630-£780|
|Cost of moving pipes||£190-£310|
|Mechanical flush before installation||£440-£535|
As you can see, there’s a really wide variation between the bottom price and the top price. That variation is caused mainly by the cost of the boiler you choose. Please do bear in mind that most homeowners will choose a combi boiler which costs them between £625 and £1,250 so you should expect to pay no more than £1,885 to £2,500 when you factor in installation charges. In addition, mechanical flushes are only needed when you’re replacing a very old boiler system. What that means, in probably 85% or more of installations, is that you won’t need to budget the £440 to £535 it costs into your calculations. Later in this article, we’ll look at the other factors that influence the price of a gas combi boiler installation. Benefits: A new gas boiler is likely to be more efficient than your old one. More cost effective resulting in you probably being able to save a significant amount of money on your fuel bills every year. It is also possibly going to be more compact than your old one thus taking up less space.
There are a number of different key factors that not only influence the price of the boiler you pay but which also influence how suitable the boiler is for your home.
Dimensions – first is the height, the width, and the depth of your boiler. If your replacement combi boiler is going into the same place in your home where it is now, your installer will probably recommend a boiler which is exactly the same size or very close in size. If you’re moving the boiler to a new location in your property, be sure to tell the installer where you want it to go to so that he or she can recommend a boiler which fits comfortably into the place you have in mind.
Flow rate – the flow rate lets you know how many litres of water your combi boiler can handle every minute. The more taps you have around the home, the better it is to have a higher flow rate.
Output – closely connected to the flow rate is the output (measured in kilowatts (kW)). You want your water to be hot when it comes out of the tap or out of the shower. To achieve that, you’ll need a combi boiler that can easily heat up the amount of water that your household generally needs just when it needs it.
Energy efficiency rating – combi boiler technology has come a long way in a few years and they’ve become very energy efficient. “A”-rated boilers use 90% of more of the gas used in heating water for your taps and your radiators with “B”-rated boilers coming close behind at 85-89% utilisation. The more energy efficient your boiler, the lower your gas bills.
What other factors does an installer consider when making a combi boiler recommendation for your home? Of course, every property is different and the people living in these properties have different needs but here’s the general rule of thumb installers use:
If you get the right boiler, you’ll benefit every year from sizable savings on your utility bills. Get it wrong and, although you’ll have all the hot water and heating you’ll ever need, you won’t see the savings on what you pay for your gas because your new combi boiler will cost a lot more to run.
There are six main boiler manufacturers in the UK and installers prefer to work with these big brands because of the quality of the combi boilers they produce and the length of guarantees they offer to clients.
Established in 1962 and suppliers to Sandringham Estate, Worcester Bosch score very highly on internet review sites with both customers and installers.
Worcester Bosch combi boilers guarantees last between 2 years and 5 years depending on the actual model you choose with your installer.

These people are well managed and they provide outstanding support in all the aspects. Keep it up.

We endeavour to procure bespoke, free, no obligation quotes from potential suppliers of products and services to each of our customers, such as you, that make an enquiry via our website. This is a quote finding and supplier introduction service; we do not ourselves provide the products and services that you may require. We provide these services to consumers and businesses.
We aim to provide 1-4 quotes within 36 hours from your online completion of an enquiry working in conjunction with data controllers who specialise in the delivery of competitive supplier quotes. The number of quotes that we will try and help you to receive does vary depending on the product or service that you are looking to receive quotes for. If we do not call you before passing your details to the companies that supply the quotes we will stipulate the maximum numbers of companies that we will pass your details to when you enter your details in our product specific web form. If you have enquired about double glazing on our website one of the companies that we work closely with is Safestyle UK plc. Depending on your postcode area and requirements we may pass your details to Safestyle UK plc. We will reconfirm this when we speak to you on the phone.
To be able to deliver suitable quotations to you we send your personal data and the details of your requirements to potential suppliers.
We offer a price comparison service. All of the companies that we deal with know that you are conducting a comparison, hence they will often offer cheaper prices, for example on labour, than they would were they approached directly by a customer, hence our service has the potential to get you big discounts.
To provide our service we first explain in more detail how we use your personal information so that the consent you give us, which is detailed in the next paragraph, is fully and fairly informed.
You may seek further information about the scope of the consent as well as vary or withdraw your consent as outlined under the heading “What are my rights in relation to the personal data that you hold?”
We obtain personal information and business information (for business products and services) about you, only from you, and do not acquire information about you from anyone else.
First, to provide our quote finding service we will ask you manually to supply us via the website with your personal details namely: First Name, Last Name, Email Address, Telephone Number, Street, House Number, Post Code and Company Name (for business products & services). You may also be asked on the website and by follow up telephone call for further information to help us process your request for quotations.
Second, information is obtained electronically when one computer connects with another across the Internet as when you visit our website such as such as your computer’s unique numerical Internet address (IP address). Information so obtained while necessary to the operation of and communication between computers may well also allow you as owner of the information to be identified, much like a name and address, and thus constitute personal data. The law requires such information to be identified and so far as practicable, for informed consent to be given by you, before the electronic information is passed from your computer to ours. Further explanation about the automatic electronic collection of your information is provided under the heading “Your electronic information”.
We do not use your IP address to identify you personally but these logs may contain unique identifiable information left by your computer.
We may use IP addresses to ensure that we are not receiving fraudulent registrations from the same IP address as evidence in the event of being challenged for unsolicited marketing. The IP address log would show that a registration took place on a given day.
We provide our service to both consumers and businesses. The way the service works is very similar but due to the nature of the products and services and the suppliers of these, the processes are slightly different. From your perspective, you will receive the same level of service from us and your expectations in terms of receiving quotations from appropriate suppliers that you can then choose from are the same.
The processes how your data will be used are explained below.
After you submit your details we may phone you to discuss the products or services you seek from a suitable supplier, to check we’ll be able to meet your needs and, should you still wish to go ahead with us, to get you free and no-obligation quotes. This will normally be us but below explains how it works with the different products and services that we are able to help in the quoting process with.
At times we work as the appointment booking agent for the companies working on our network so even if you have requested direct contact from the company you may still receive a call from us in order to book the appointment for your quotation.
For certain home improvement enquiries we may not at the time you register with us have an installer who can provide quotes for that product. If that is the case we will pass your details to another quote finding company (in a secure manner) who will call you to see if they can match your details with some installers of that product. They will not use your information to do anything other than to call you about the product that you enquired about.
Enquiries for business products and services are handled by Leads 2 Trade Ltd.
If you have come to CompareCompanies looking for businesss products or services Leads 2 Trade will transfer your business and personal details on to up to four companies. Before passing your details to up to four companies we will check your details and match your details to a number of businesses to find the best deals. The businesses may contact you by email, telephone (including automated calls) and/or SMS. Quotations may be provided to you by appointment or electronically and you will be told over the phone how you can expect yours to be delivered.
We take your details and pass them on to one or more companies that can provide the type of product or service that you are looking for and will invite those companies to submit quotes for your consideration.
We pre vet all companies that join our quote finding service as potential suppliers to our customers, such as you, to ascertain as best we can that they will be suitable for your requirements and will keep your personal data safe. However, the final responsibility for determining suitability to supply the product or service lies with you, the customer, when considering the detailed quotations and deciding if you wish to contract with a given supplier or suppliers.

However, the final responsibility for determining suitability to supply the product or service lies with you, the business customer, when considering the detailed quotations and deciding if you wish to contract with a chosen, given supplier.
We are not responsible for the standard of work carried out by the suppliers that provide you with quotations as a result of your enquiry via our site. There is no warranty provided by us, implied or otherwise for the products or services provided by any suppliers that you contract with. Individual suppliers may offer their own warranties, but these and any standards of workmanship are not in any way associated with Leads 2 Trade Ltd. or its partners.
We take the security of your data very seriously from the outset. Our web address is HTTPS. (HyperText Transport Protocol Secure) This is the protocol used to access a secure Web server. We use https:// as the prefix to our Web address rather than the common http://, so that your session is managed by a security protocol and the transmission of data is encrypted to and from the Web server.
Secure certificates (SSL Certificates) are in place. These are small data files that digitally bind a cryptographic key to an organisation’s details. These allow secure connections from a web server to a browser. SSL is used to secure the transfer of your data to our server.
Our server is protected by a firewall. Log in details are securely shared internally between employees.
Any personal data held in our database is encrypted. If there are any security breaches, your data is encrypted and therefore secure.
Each supplier to whom we pass your information in order to provide you with quotes has contracted with us to keep your data safe and use it only for the provision of a quote and, if selected by you, to provide the product or services you require.
We always have contracts in place with the companies that we pass your details on to both to ensure that they will keep your data secure and that they comply with the rules of the GDPR (General Data Protection Regulation) which we also operate within.
Please be assured – we will not use your details for marketing or use or pass your details to third parties other than as described in this statement without explicit consent from you.
Finally, please note that the transmission of information via the Internet is not completely secure. Although we will do our best to protect your personal information, we cannot guarantee the security of your information transmitted to our site; any transmission is at your own risk. Once we have received your information, we will use strict procedures and security features to try to prevent unauthorised access.
We rely on your explicit consent to process your personal data. This means that we ask you to consent to the following use of your data:
We will email or text you about similar products and services. We will only do this if you haven’t opted out of receiving such emails or texts.
We like to work with Facebook, Google and other platforms (“Platforms”) to reach out to you with adverts for Other Products. We also like to use Platforms to reach out to other people who might like to use our quote request service.
We do this in two ways. In both cases, your data, along with other data, is used to create a custom audience and/or a lookalike/similar audience. Whenever an audience is shared with a Platform, the data is first hashed and pseudonymised, meaning that any data within the audience that could identify a person is replaced with an artificial identifier. So, the process is secure. Also, we don’t share more data than we need to for the purpose of creating the audience.
We share your personal data within our business and with data processors who can find suitable product and service suppliers for you. Your data will then be used to enable suppliers to provide quotations and potentially move towards a contract with you.
Some of the suppliers that may offer products and services to you are based outside of the EEA.
We transfer your data as detailed above with your consent.
We keep your personal data for no longer than is necessary for the purposes for which it is being processed. This is to reduce the risk that it will become inaccurate, out of date or irrelevant.
We ensure that your personal data is securely disposed of when no longer needed.
Your rights are embodied in the contract formed between us when you visit the website (as subsequently augmented when submitting your personal information and, if you are called, when speaking on the phone) and as contained in the General Data Protection Regulations 2018 – also known as GDPR.
If you have any questions or concerns please first read this section of the statement and then email our Data Protection Officer on firstname.lastname@example.org, They will be pleased to assist before as well as after you may have provided personal information to us.
You may also write to our Data Protection Officers either at our registered office address stated at the outset of this statement.
If you need more information about data protection you might contact the Information Commissioner: see https://ico.org.uk/global/contact-us/email/
The GDPR provides individuals with the rights in relation to personal information about themselves which is held by us as summarised in the table below.
Some of the rights are unlikely to be of practical use. For example, if you wish for a copy or correction or cessation of use of some or all of your personal data we, our suppliers and our other introducing companies are likely already to have eradicated it from our or their system given the short periods your date is retained and its limited use.
Nevertheless, the GDPR principle of transparency in particular provides you with the right to enquire and to be informed and we briefly set out all of the rights here. Further information about the rights and the circumstances in which they apply may be obtained from a number of published sources and from our fact sheets which are available on request.
Information Right – you may require us to provide a more detailed explanation of how we collect, process and use your personal information.
Personal Data Access Right – you may require us to provide an electronic copy of your data free of charge.
Personal Data Correction Right – you may require us to correct your personal information as held by us.
Personal Data Erasure Right – you may require us to permanently erase the personal data that we hold about you.
Data Processing Restriction Right – you may require us to stop using your data for particular purposes such as mailing or profiling.
Data Processing Objection Right – you may require us to suspend using your data if for example it is incorrect or you simply wish to withdraw your consent.
Data Portability Right – you may require us electronically to transfer your personal information to another supplier, for example to facilitate switching.
Automated Decision-Making Right – you may require us not to make decisions about you relying solely only on a computer decision.
Breach Notification Right – if in the unlikely event there occurs a breach of security which is likely to result in a high risk to your rights as a data subject, we must inform you without undue delay.
Rights aside, if you have a change of heart and do not wish us to pass your information to potential suppliers or another introducing company please let us know immediately by email or, should we call you, during our phone conversation and we will remove your information from our and their systems.
You are not bound to enter into a contract with any supplier that provides a quotation to you and can unsubscribe from any communications related to your enquiry from them or us at any time.
If you have any questions, please email email@example.com.
