If you reside in a bungalow or own a house with a low roof-line then this conservatory may appeal as there is great flexibility with regard to the height of the roof.

Lean to conservatories can be constructed using either floor to ceiling glazed units or a dwarf wall can be incorporated.

What affects the price of a lean-to conservatory?

These are the seven factors that can greatly influence the cost of building your lean-to conservatory:

  • The size (the bigger your conservatory, the bigger the price tag attached to it)
  • The base (ready-made bases are typically much cheaper than traditional footings that need to be dug out manually)
  • The material for the frame (prices of softwood, engineered wood, uPVC, hardwood and aluminium all vary for the same sized room)
  • The roof (roofs made from polycarbonate are usually the cheapest option while double glazed and tiled roofs cost considerably more)
  • The glazing and doors (the energy rating of doors and glass can impact their prices)
  • The walls (dwarf-wall features create a definite increase on the price of your conservatory)
  • The company quoting you for the work (two different contractors can give you two very different quotes. To avoid any extra unnecessary costs we advise that you get at least 4 quotes to find the best price)

    Are you having a dwarf wall installed on your conservatory?

    A dwarf-wall is a low wall which is used as the base for the perimeter of a conservatory. These walls are typically no less than 1 meter tall and feature panels or brickwork to create an aesthetically and appealing outside look to your conservatory. However, adding a dwarf-wall feature to your conservatory will add to the amount that you have to budget for.

    Your installer needs to prepare the base or foundation of your lean-to conservatory

    Your conservatory needs to be constructed on a solid base to ensure that it remains stable at all times. You do however have a choice of three different types of foundations or base.

    Traditional footings are one of the most options you can create a base with however they are very labour intensive meaning that the whole installation may take a little bit longer. If your professional installer tells you that your ground as poor but that you still choose to place a traditional footing, they will need to dig a deeper hole than usual to create your foundation.

    Concrete raft bases are another option to consider when selecting which type of base your conservatory will have. This type of base is essentially a slab of seven-inch pre-mixed concrete that is poured into a steel reinforced mesh to create your desired conservatory shape.

    The last option is to have a steel base fitted for your conservatory’s foundation. Steel bases are a popular option possibly because of how easy they are to install. They typically come ready-made with if you select a standard lean to conservatory design.

    Which material do you want to use for the frames?

    The material you choose for your conservatory significantly alter the final price you’ll end up paying. If you use hardwood, your conservatory will cost more per square foot than if you pick aluminium or uPVC as your framing material instead.

    When choosing the materials you want for your conservatory, you shouldn’t only consider the price but the qualities of each type of material too. There’s not just one standard choice of uPVC, aluminium, or hardwood – there are lots of options.

    For example, if you decide you want aluminium windows but you decide on using a very cheap aluminium, it is less likely that your conservatory will have the built-in thermal breaks necessary to stop the interchange of hot and cold temperatures from outside and insider.

    Although it’s understandable that you may initially want to cut costs by choosing a cheaper material, your conservatory is more likely to experience condensation problems towards the end of its warranty period and it may even be unusable in particularly hot or cold weather. In the long run, you may end up spending more money on utility bills trying to keep your conservatory warm in the winter and cool in the summer.

    Be certain to choose the right material of a high-enough quality that fits within your budget.

    What type of door and how many doors do you want on your lean-to conservatory?

    Many home owners with conservatories choose to install a single set of French doors because they appreciate their simple yet classic appearance. However, you may decide that sliding, bifold, or tilt and turn doors create the type of look and feel for your conservatory that you prefer.

    If you’re considering purchasing a more complex door fitting for your conservatory, you should note that the overall price of the installation will increase, sometimes by a lot, depending on the door’s design, size, and the material it’s made from.

    What type of lean-to conservatory roof Replacement you want ?

    While most standard lean-to conservatory roofs typically have the same sloping roof, you can customise your unique roof by selecting the material from which it will be made.

    If you choose to install a fully glazed roof, a sheeting of glass or polycarbonate will run from the ceiling to the floor of your new conservatory. This can be an attractive option for homeowners who want to create an airy room that lets in the most amount of natural sunlight.

    Alternatively, you can choose to install a part-glazed roof onto your lean-to conservatory. Part-glazed roofs typically have a dwarf-wall feature from the ground up to 3 foot on average, after which window panel walls continue up to the height of the ceiling.

    Last, you could choose a solid, fully tiled lean-in conservatory roof. These types of roofs tend to be higher in price than their window-panel-based alternatives and that’s because of the additional materials and labour costs. Although this type of roof is often more expensive up-front, you may find that a tiled roof helps to regulate your conservatory’s temperature making your new space more enjoyable.

    Internal features

    Although most of the options you can choose from when you’re selecting your conservatory are focused on the outside, you should also carefully consider the features you really want on the inside too. Things to think about include:

    • How many power sockets do you need?
    • Do you want multiple light switches?
    • What type of heating system do you want? (underfloor, radiators, air conditioning)
    • Do you want a tiled or wooden floor?

    Your questions answered

    What can a Lean To conservatory be used for?

    It can be used for a variety of purposes such as:

    • A playroom for the children also providing them with access to the garden.
    • As an additional living room to relax in at any time of the day or night and throughout the year especially as there are so many choices of heating system.

    Planning permission for lean-to conservatories

    While planning permission isn’t typically required to install a lean-to conservatory in most cases, you may require one if any of the following statements apply to you:

    • Your home is a listed building,
    • Your home is subject to Directive 4
    • If you live in a conservation area
    • If the conservatory extends more than three metres away from the wall to which it is being attached (for metres if you live in a detached house)
    • If the height of your conservatory is more than 4 metres

    You should contact the planning department at your local council to discuss your case before committing any money into your project if you meet any of the criteria listed.

    Conservatory installations – how long do they take?

    You should typically wait no longer than 4 to 5 weeks from the time you place your order to have your lean-to conservatory installed. While some contractors may quote you a shorter time frame of 3 to 4 weeks, several factors can influence the amount of time needed to complete the installation process of your lean-to conservatory start to finish.

    For example, other than planning permission requirement, the following will affect the time it takes:

    • How long the groundwork will take
    • Any non-standard design extras you have requested
    • If your conservatory is not of a standard size and some or all of it has to be manufactured bespoke to your home.

    Should my lean-to conservatory installer belong to any trade body?

    Yes. The professionals you choose to install your lean-to conservatory should belong to a trade body. That’s because, by joining one, this means that they have made a promise to follow their strict rules of conduct on build quality and after-sales support.

    By hiring an installer who belongs to one or more of these bodies, this offer your peace of mind about the quality of their work and how sustainable their business is. We recommend that you work with lean to conservatory roof installers who are members of or who are accredited to the following bodies:

    • The Fenestration Self-Assessment Scheme (FENSA)
    • Certification and Self-Assessment (CERTASS)

    What should be on the quote for my lean-to conservatory?

    It’s important to make absolutely sure that you’ll pay no more to an installer than the price you see written on the quote. Make sure that your quotation contains all of the following information:

    • Everything that’s included for the price
    • Whether VAT is included in the price or not
    • The time frame you should expect your lean-to conservatory to be fully installed within
    • The agreed payment terms
    • If you are buying using finance that your installer has arranged, what the monthly repayments are, how much interest you’ll pay over the life of the loan, and if there are any early repayment penalties.
    • Whether an insurance-backed warranty is offered meaning that, if your contractor stops trading, your lean-to conservatory will be repaired by a substitute company.

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.

    Keeping your details safe…

    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.

    Lawful basis for processing your data

    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:

    Business users only

    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.

    To create custom and lookalike/ similar audiences

    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.

    Transfers of data outside the EEA (European Economic Area)

    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.

    Data Retention Policy

    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.

    What are my rights in relation to the personal data that you hold?

    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, 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

    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.

    How else can we help?

    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.
