Should I Buy a DIY Conservatory?

DIY (or modular) conservatories are made to specification and delivered in kit form. They can be assembled without causing any mess – as no drilling or nailing will be required. If you feel confident building the base – which is the hardest and most expensive part – and are confident that your supply is selling quality materials that are backed by manufacturer guarantee, then you probably should buy a DIY conservatory in Harrow.

Whether you go via the supplier route, or instruct an installation company to fit your conservatory, you need to be sure that the company you choose is accredited. The Double Glazing and Conservatory Quality Assurance Ombudsman Scheme (DGCOS) strictly vets its members and has access to a compensation fund in the event that a homeowner needs to make a claim resulting from problems arising out of their installation. Should you buy a DIY Conservatory in Harrow? If the installer is DGCOS registered – or accredited with an equivalent body – then you should be safe to proceed.

What is the Best Type of Conservatory?

There is no definitive answer to this question. What is the best type of conservatory in Harrow? It will come down to what you afford in part – and, in any case, ‘best’ is a subjective term. That said, Victorian style conservatories are extremely popular – and so we thought we’d look briefly at the different installation options available.

Victorian Conservatories can be constructed in either 3- or 5-facet form (facet being another term for sides – each of which will contain a window that’s widely angled to optimise space and let in as much light as possible). The former is suitable for most types of homes and locations. Because the latter utilises Bay Windows – which project outward – it owns a more classical look and so may better suit classical/period-styled properties.

So, what is the best type of conservatory for Harrow properties? The Victorian is worth considering, as it can be adapted to suit modern tastes too; but it could overwhelm a smaller dwelling, rather than complementing its style. We would recommend looking at the different types of conservatory listed on our website to get a better idea of what’s available.

Our accredited installers can help you decide what is the best type of conservatory for Harrow houses; request a quote from us and we’ll take the time to call you and see if you’d like further information about local installers.

Fully Fitted Conservatory Prices

Once you’ve shortlisted some installers – and have verified that they’re accredited to a lead body (for example, DGCOS) – it’s time to start collecting some fully fitted conservatory prices. But what should you expect to pay? As a general guide, you will be looking at a total cost of somewhere between £5000-£20000.

Without knowing more about your budget and preferences, it’s hard to be precise. The cheapest form of conservatory is the Lean-To. Its design is simple and, because it is always rectangular or square in shape, you won’t have any wasted space. You can reduce your fully fitted conservatory price if you use the existing walls of your home as solid sides (this can include a garden wall). In rare cases, a Lean-To could cost as little as £2000.

The Lean-To may not suit a classical/period property, which may be better complemented by a style like the Victorian. This can be built with either 3 or 5 facets (the latter uses a bay window) and you should expect to pay upwards of £13000 for one of a high quality.

As you can see, fully fitted conservatory prices in Harrow will vary. For a free online guide price, use our conservatory cost calculator.

Is an orangery better than a conservatory?

Orangeries aren't better – just different. Conservatories tend to be more popular with homeowners because they look different stylistically and therefore stand out. Orangeries are primarily of brick construction, so they tend to blend in with the architectural design of the property (they are often mistaken for extensions). Most installers now offer orangeries as well as conservatories, so you can seek further advice when calling around for quotes.

How do I find trustworthy installers?

Installers will list any accreditations they have on their website. An accredited company will have been vetted by an organisation/ombudsman already – and often that body will be able mediate in the event that a dispute arises between the customer and their installer. Under no circumstances should you use a company that's not affiliated – as you'll have no protection or support if things go wrong.

How much is a conservatory?

The cost of a conservatory is open-ended. Buying a DIY conservatory can save you thousands – but the build quality isn't always as good as a fitted one. With prices ranging from £5000-£20000, it's best to shop around and get advice from as many installers as you can. We can get you talking to conservatory companies in Harrow, so please request a quote from us so – we'll then call you to discuss potential installers based near you.

Frequently Asked Conservatory Questions

IThe majority of conservatories with a tiled conservatory roof will not require planning permission. This is because they are covered under what is known as a 'permitted development.'

However, Building Regulations will apply if you want to build an extension on your home.

Whether you are looking to invest in a brand-new conservatory, or just wanting to replace your existing conservatory roof, there are many conservatory roofing options available. The most popular conservatory roof materials are:
  • Solid Roofs
  • Glass
  • Polycarbonate

Solid Conservatory Roofs

If you are looking to achieve a more contemporary appearance, then a solid conservatory roof provides the perfect combination of conservatory and home extension. This conservatory roof option allows you to make use of the space you have, providing you with a living area you can use all year round.

Worried about light? Roof windows or glazed panels can be incorporated into the design, enhancing natural light for a light and airy feel. A lightweight tiled roof conservatory is also up to 15 times more thermally efficient than any other roof.

Polycarbonate Conservatory Roofs

Polycarbonate Roof Ideal for those on a tighter budget, a polycarbonate is often seen as a cost-effective option to roof glazing. They come in many different options such as different colours, shading and U-Values.

Typical colours include Bronze, Clear and Opal.

Glass Conservatory Roofs

Glass conservatory roofs are a popular choice because they provide great temperature control. They help to prevent your conservatory from being too hot in the Summer and too cold in the Winter.

It can also be specified with self-cleaning properties, helping to keep roof maintenance to a minimum.

In most instances the council tax will not increase on a property unless the additions another living quarter or self-contained annex. This means the addition of a conservatory should not increase the council tax payable on a property. To be absolutely certain you can always check the government's website which gives advice on council tax.
The main difference between a conservatory and an orangery is how the roof is constructed. A conservatory roof is over 75% glazed whereas an orangery roof has less than this amount. A conservatory also has over half of its wall space glazed whereas an orangery can include more brickwork than this.
Yes, you can put a conservatory on the front of your house. This is because conservatories come under the category of a permitted development. As such in most instances you do not need planning permission. This applies if the area surrounding the original house is not more than 50% covered by other buildings or additions.
A glass conservatory can cost as little as £4,000 depending on the style you choose and the amount of building work you need. Larger glass conservatories with more building work can cost £20,000 and above. If you know the conservatory style and size you need or just want an idea of cost our online conservatory cost calculator will give you a guide price.
A Loggia Conservatory can cost about £15,000 to £20,000 for an average size. The Loggia Conservatory is a popular style but can be more expensive than traditional conservatory styles.
A Loggia Conservatory can cost between 20% to 50% more than a uPVC conservatory. It is a good idea to shop around for quotes in order to get a competitive conservatory cost.
The average conservatory cost begins in the region of £4,000 to £5,000. This will be for a reasonably small and basic conservatory. The cost of a conservatory can be as much as £40,000 to £50,000. This will be a large conservatory, fully fitted with all building work included. As this is a wide spread it is a good idea to know your style and size in order to get an average conservatory cost.
The majority of conservatory roofs can be replaced within the course of a day however, this is dependent on design. A solid conservatory roof with added extras such as lighting, might take longer than a day.

Your chosen conservatory installer will protect any existing finishes during the project so no need to worry about your existing floor being damaged during transformation.

Orangeries have more solid wall and roofing than a conservatory. This means they are able to retain more heat in the Winter and stay cooler in the Summer.
However, modern conservatory extensions such as a tiled roof conservatory or solid roof conservatory, can offer just as much warmth.
There are many ways of gaining temperature control. Conservatory blinds, ventilating windows, cooling film and air conditioning to name a few. You might also want to consider replacing your conservatory roof with a tiled or solid design.
There are many ways of keeping your conservatory warm in the Winter. If you have a small conservatory then an electric heater will suffice but those with bigger conservatories may want to look into installing underfloor heating.
Glazing is also very important in a conservatory. Most heat can be lost through glass so ensure your conservatory glazing is thermally efficient. You can also tackle draughts or cold spots by installing conservatory blinds.
This will largely depend on your location. You will find that certain areas have different setbacks based on the use of the building. We recommend that you check with your local council or take a look at the Goverment's Planning Portal.

You must notify your neighbour if you want to:

- Build on or at the boundary of your 2 properties - Work on an existing party wall or party structure - Dig below and near to the foundation level of their property
Replacing your conservatory roof can indeed make your conservatory warmer however, this will depend on the type of roof you choose. A solid or tiled conservatory roof will offer greater insulation than a plastic or glazed roof.
A solid roof can be put on a conservatory. There are many solid conservatory roof designs available - just ask your chosen installer for a recommendation. The majority of new-build conservatories with a solid, tiled or glazed roof will not require planning permission. They are covered under what is known as 'permitted development'. However, building regulations will apply if you want to build an extension.
When it comes to your home improvement, it's important to have all the necessary legal documentation. The installation of a conservatory, orangery or porch does not require a FENSA registration form.
The average life span of a uPVC conservatory is largely dependent on the quality of materials and build. Typically, a uPVC frame can last up to 25 years but some can last for decades ensuring they are well maintained.
Planning permissions used to say that a certain percentage of roofing must be translucent in order for a conservatory to be exempt from planning permission. Changes to building regulations however, now means that you may not require planning permission for roof replacement.
Swapping your existing conservarory roof for a tiled or solid roof replacement can be done without needing to file for planning permission. Planning permission may be required however, if the height of your extension is changed following completion.
A conservatory is defined as a 'building that has no less than 75% of its roof area made of translucent material and no less than 50% of its total wall area made of glass.
It is possible to convert a conservatory to an orangery but it isn't a simple process. A surveyor will need to come out and assess your property and conservatory to see if it is at first , feasible.
Both extensions and orangeries often require planning permission and in order to satisfy requirements, a new structure will have to be built.
If a conservatory is within two metres of a boundary, a conservatory should not be higher than three metres. It must also not extend beyond the rear wall of the original house by more than 3m if an attached house or by 4m if a detached house.
For construction work to begin a trench will need to be excavated to a minimum depth of 600mm. A conservatory needs footings just as much as any extension does.
Solid ground will need to found first and needs to be accepted by Building Control as being a minimum of 1 metre in standard conditions.
Foundations will need to be dug and because conservatories are lightweight in structure, their foundation loads are usually quite low. This can often lead to the notion that shallow foundations are satisfactory however, shallow foundations are more susceptible to subsidence.

Conservatories that are built with foundations shallower than the Building Regulations advise, are likely to encounter problems.

Building Regulations state:

A2. The building shall be constructed so that ground movement caused by :-
(a) swelling, shrinkage or freezing of the subsoil; or
(b) land-slip or subsidence (other than subsidence arising from shrinkage), in so far as the risk can be reasonably foreseen, will not impair the stability of any part of the building
Usually, there are no planning requirements when it comes to building a conservatory to a bungalow. However, the conservatory will be subject to certain conditions so be sure to check with your local building authority or with the Government's Planning Portal to ensure your conservatory remains within these guidelines.
Any structure that is built as an extra living quarter will require its own council tax band, even if it shares facilities with the main dwelling. If you're adding a conservatory then council tax won't be an issue however if you're adding a whole new annex, then your council tax is likely to change.
On average, an orangery can cost anything from £10,000 to £20,000. It is likely to cost double the amount of a conservatory, however it's important to note that an orangery provides more functionality and home value when compared to standard glazed conservatory.
An orangery allows you to benefit from both conservatory and extension, being a combination of the two.
When is a conservatory not a conservatory? In order for a structure to remain a permitted development (a conservatory), the build needs to comply with a number of rules. A conservatory must be ground level, must not be more than 30m2, must be thermally separated from the original building, have its own heating and have glazing in critical zones that meet Part Nof the building regulations.
An extension refers to an additional structure that is anatomically in-keeping with your main property. An extension often requires planning permission unless it is classified as permitted development and is built with opaque cavity walls and brick-based foundations. Extensions are a big home improvement and investment, needing the work of an architect.
Conservatories or glazed extensions are perfect for those looking to add extra space on a budget. Typically, they are less of a logistical strain and in most cases do not require planning permission,
A conservatory can be built under permitted development rights, not needing an application for planning permission. A conservatory however is subject to the limits and conditions listed here. Building a conservatory onto an extension however, will be subject to different conditions. In some cases and under the permitted development regulations, you cannot attach an extension to an already extended part of a dwelling. It has to be attached to the original walls of the dwelling house.
A well built conservatory can increase your home's value by up to 7% . A conservatory can add lots of value to your home, increasing monetary value and making it much more attractive to a prospective buyer. A conservatory extension will change how you live and interact in your home for the better, enhancing space and comfort. It will certainly put your home above other properties too, especially when it comes to attracting a potential buyer. Read more here.
Conservatories are generally much cheaper than a single-storey extension of the same size. The price difference will largely depend on size and how complex the structure is to build, as well as the quality of materials.
The cost of a conservatory extension can range from £6,000 to £20,000. Compared to a full on extension, it is a much more affordable way of increasing space within your property. A full blown extension can cost up to £30,000. An extension is priced on average, per square metre.
A conservatory or single-story extension can be built without planning permission if: It's a maximum of 4 metres high or 3 metres high, within 2 metres of a boundary and the conservatory or extension does not cover more than half of the garden.
From now until 2019, you can extend outwards by up to 8 metres for detached homes and 6 metres for other property types. For this, instead of applying for planning permission you will need to undergo a Neighbour Consultation Scheme.
Fully fitted conservatory prices start from around £4,000 for a small room up to £20,000 + for bigger, more bespoke rooms. To get an idea on how much you can expect to pay for your new conservatory, you can use our conservatory cost calculator. It will provide you with a unique online guide price based purely on your own specifications. Fully fitted conservatory prices will vary from company to company and is also very much dependent on design.
In most circumstances, building regulations tend to apply when you build a new extension or a very large structure to your property. However, most of the time, conservatories are exempt from building regulations when they are erected at ground level and the floor surface areas is less than 30 square metres.
The average life expectancy of a conservatory depends on the quality of materials used as well as the installer. Generally speaking a conservatory built with uPVC window and door frames can last up to 25 - 30 years.
Conservatory extension costs are far more affordable than a full-blown extension. A conservatory costs anything starting from £3,000 - £4,000 deadening on final styles and specifications. On the other hand, full build house extensions can cost anything from £20,000 right up to £100,000+! Generally speaking extensions are priced on average, per square metre.
It is possible to build either a conservatory or a single-storey extension without gaining planning permission if: firstly, it has a maximum height of 4 metres or 3 metres high if situated within 2 metres of an existing boundary. The conservatory itself does not exceed over half the size of the garden.
The average cost to build a conservatory varies depending on many factors such as: size, style, materials, roof, number of windows and doors, building work requirements and internal works e.g. lightning, plastering, finishing etc. On average, costs for smaller type conservatories such as the lean-to conservatory style will start from around £3000 - £4000 including VAT and installation (subject to final requirements and technical survey).
Yes you can! Whatever the shape of your existing conservatory, you can be sure that there is a solid roof equivalent to meet your exacting requirements.
Changing roofs from a polycarbonate to a solid roof means that building regulations will apply. Your chosen installer will be able to answer any questions you have and help with any red tape such as contacting local authorities to resolve building regulations compliance.
