How Much Are Fully Fitted Conservatory Prices?

Adding a conservatory to your home can provide extra light and space, but many homeowners wonder “How much will a fully fitted conservatory cost me?” When planning your conservatory build or renovation, it’s wise to understand what factors impact the pricing so you can set a realistic budget. In this article, we’ll break down the main costs that go into a fully fitted conservatory installation.

What Factors Affect Conservatory Cost?

Several main elements contribute to your total conservatory cost. Key factors that influence pricing include:

Size of the fully fitted Conservatory

Not surprisingly, the dimensions of your fully fitted conservatory will greatly impact the overall price, since that determines the necessary materials and labour. Larger builds naturally require more of both. Expect to pay more for a sprawling, open-concept conservatory versus a compact, cosy space.

Type and Style of the Fully Fitted Conservatory

The shape and architectural style you choose will affect quotes. A fully fitted lean-to conservatory that connects to an exterior house wall tends to be simpler and cheaper than other ornate styles like a Victorian, T-shaped, or P-shaped build that may demand more complex engineering.

Glazing and Material Choices for a Fully Fitted Conservatory

Glazed elements like glass or polycarbonate panels will likely be your biggest ticket item in terms of supplies. Glazing can account for up to 50% of the total conservatory cost. But you have options here to suit different budgets.

Type of Glass

Specialised glass like double glazing provides better insulation but costs more than standard single panes. Laminated and toughened safety glass also comes at a higher price point. Consider how much temperature regulation and security matter for space.

Frame Material

Wood frames offer a classic, natural look but require more maintenance over time than more durable uPVC and aluminium counterparts. Though metal materials have a higher upfront cost. Determine the long-term value based on your needs and style preferences.

Heating, Cooling, and Ventilation

Since conservatories have so much exposed glazing, it’s key to assess heating and cooling early on. This can significantly sway fully fitted conservatory cost estimates.

Heating System

An affordable heating method like wall-mounted radiators may suffice if the space mainly gets used in warmer months. But installing luxury underfloor heating pipes for year-round comfort contributes more to the end cost.

Cooling System

You may not require active cooling for the conservatory with a good cross ventilation. But adding a ceiling fan or AC unit during the build is easier than retrofitting later.


Ensure proper airflow and temperature regulation by factoring in enough vent placement during construction. Opening side and roof windows tend to provide sufficient ventilation at a reasonable price.

Electrical & Plumbing Work

Running new electrical lines and plumbing for a conservatory comes with labour fees. So only incorporate what’s essential to your plans to keep this expense down.


Good lighting may require upgrades like new circuits, switches, and fixtures. Wall sconces and overhead pendant lights suit conservatory styles while recessed can lights add helpful task lighting.

Power Sockets

Think about whether you’ll want sockets around the space to plug in table lamps, speakers, or electric patio heaters down the road. Pre-installing these during the build saves conservatory costs later.


A basic floor drain for capturing rain runoff is advisable, though more complex sinks, toilets and water lines substantially increase plumbing prices. Consider your needs.

Base Work and Foundations

safety and stability of conservatories requires solid base structures as their groundwork before erecting walls and roofs.

Concrete Base

A standard concrete foundation generally works for smaller, single story builds. This budget-friendly base option still ensures durability.

Connecting to House

For larger conservatories or multi-level builds, costs are higher to securely connect beams to the existing house structure. This usually demands involvement from structural engineers.

Additional Elements, Fixtures & Fittings

Finally, factor in finishes and accessories as part of your total conservatory price. The conservatory fixtures you select largely influence this portion.


Entry doors range widely, from affordable patio doors to intricate French doors or bi-folds that carry higher price tags and require special fittings.


Much like doors, window styles and features determine costs. Basic casement windows tend to be cheaper than more complex bay or dormer styles in terms of both materials and labour for installing them.

Blinds and Curtains

Consider useful shading solutions like internal roller blinds or pleated curtains to block light and heat when needed. Price these into initial plans if possible.


For flooring, decorative tile and natural stone come at a higher cost than basic concrete floors, but can enhance aesthetics. Laminate wood-effect vinyl makes for an attractive, wallet-friendly option.

Shelving and Storage

Build in shelves or cabinets during the construction phase to avoid later hassle and keep costs lower overall.


Constructing a fully functional conservatory means carefully weighing options at each stage – from structural supports to finishes. Now that you know the main elements impacting cost, from size and layout to material choices and fixtures, you can determine an accurate budget and shop quotes accordingly. Planning ahead for all desired features ensures your conservatory build stays on-budget while maximising usable space tailored to your family’s needs.


What’s the average total cost for a fully fitted conservatory?

The average price range sits between £12,000-£20,000 depending on size and specifications. Lean-to styles on the smaller end size-wise usually fall under £15,000 while large Edwardian builds with added luxury features hit the higher end.

What’s the most cost-effective conservatory style & material?

For best value, a PVC lean-to conservatory with polycarbonate roof and basic heating provides the most affordability and functionality. expects costs around £140-£200 per m2.

How much should labour factor into my conservatory installation cost?

A general rule of thumb is 30-35% of total spend towards labour and builders’ fees for supplies and time. This covers aspects like base builds, setup, glazing, fittings, finishing and more.

Can I save money on my conservatory by doing any work myself?

If you have construction experience, opting to do preparatory work like demolishing old structures onsite or assisting with clearing the build area during the project can potentially trim some costs. Discuss options with your chosen builder.

What hidden costs might I need to account for in my conservatory budget?

Be sure to factor in ancillary expenses like added electrical, plumbing, or structural engineering needs. Also budget a 10-15% cushion for cost overruns in case unexpected building issues arise onsite. This avoids going over budget.
