Alitex Greenhouse Cost: Real 2026 Prices

Alitex does something almost nobody else in the premium glasshouse tier does: it prints real prices. Not "request a brochure" prices. Actual figures, on the actual model pages, including delivery and installation. The problem is that nobody has put them in one place, next to the older numbers still floating around the internet, so a buyer searching for Alitex cost today finds a 2018 blog post, a $60,000 headline, and an £11,250 figure that is eight years stale and barely more than half of today's price.

So here is the whole picture, dated August 2026, assembled from Alitex's own published prices, its guarantee terms, and dated press and owner reports. We don't sell greenhouses, and Alitex has not paid to be written about. For how Alitex compares to its only real peer, see Hartley Botanic vs Alitex.

Quick Answer: What an Alitex Actually Costs

Hold onto two things. First, the published price is closer to the finished number than a Hartley quote, because delivery and installation are already in it. Second, the brick base is not, and on a dwarf-wall Victorian that is real money you arrange yourself, the same base-and-foundation story as every serious greenhouse project in the real cost of a greenhouse.

The published UK price list, model by model

These are Alitex's own National Trust Collection prices as of August 2026, from the individual model pages. Every one includes VAT at 20 percent and delivery plus installation within mainland England and Wales.

Bespoke is the second lane, and there Alitex works like Hartley: a sales designer visits your site, and the price follows the design. No published figures exist for bespoke builds, so treat the Ickworth's £55,600 as the last public number before the quote takes over.

Why the numbers you have seen don't match

Search for Alitex prices and you will find figures spanning more than double. They are all real. They are just from different years and different markets, and no page bothers to say so.

• £11,250 for the Hidcote comes from a well-known 2018 comparison by The Enduring Gardener. It was accurate then, and it excluded installation of the base. Today the same model lists at £19,500, which is a rise of about 73 percent in eight years.
• £15,950 for the Mottisfont was Real Homes' reported starting figure in 2020. Gardens Illustrated quoted £25,689 for it in June 2024. Today it lists at £27,800. That is roughly 74 percent above the 2020 figure.
• From £19,500 for the Tatton was Alitex's own answer on its Houzz profile, in an undated reply from the late 2010s. Today the Tatton is £36,800, and £19,500 buys the smallest model in the range instead.
• $60,000 is not a contradiction of any of those. It is the current US floor.

The lesson is the one we apply across this site: a greenhouse price without a date attached is not information. If you are budgeting from an article or a forum thread, check when it was written, then assume today's number is meaningfully higher.

US pricing: the Kew Collection

Alitex sells a different range in the US, the Kew Collection, through Alitex U.S. LLC in Providence, Rhode Island, with the structures still engineered and made in Hampshire, England. The published US position, live in 2026: prices start from $60,000, and the entry Capel model (8'5" x 10'1", the same footprint as the UK Hidcote) is listed at $61,500 including delivery and installation in 19 listed states, most of the East Coast plus WA, OR, and CA. Outside those states, the install is quoted separately.

The same-size greenhouse is materially more expensive in the US than in the UK. Alitex does not publish a line-by-line explanation for the gap, so do not treat currency conversion as the comparison. The US number is a delivered-and-installed import price for a structure made in England and sold through a separate US operation. Ask for an itemized project quote, then compare that installed total with the UK scope and with the dated figures in what a Hartley Botanic actually costs.

If the US number stings, the honest alternative at the same footprint is a Janssens Victorian kit at $8,000 to $19,000 for the structure, real 4mm tempered glass, assembled by you or a contractor rather than a factory crew.

What the price includes, and what lands on top

Alitex's published prices are unusually complete, which matters when you compare quotes. Included in the UK list price: the structure, VAT, delivery, and installation by Alitex's own team within mainland England and Wales. Included in the US Capel price: delivery and installation in the 19 listed states. Automatic roof vents are standard across the range, not an upcharge.

What is not included is the part that catches buyers:

• The brick base or dwarf wall. Alitex's own disclaimer says it plainly: the brick base is not included, because it is tailored to your site. A masonry dwarf wall is the premium end of the base spectrum, several thousand in mason work on a proper footing, priced honestly in the foundation and base guide. Alitex offers a building-works service within about 100 miles of its Hampshire HQ, or you hire your own builder to their drawings. Get the base quote before you sign, not after.
• Benching and accessories. Priced separately and openly: greenhouse benching at £860 per linear metre, external shades from £1,880, a greenhouse heater at £380. A fully fitted interior adds thousands, and Alitex publishing the accessory prices makes that easy to see in advance, which we count in its favor.
• Heating and running power and water to the site. A single-glazed glasshouse in a real winter needs heat, and the trench, circuit, and running cost are your lines, priced honestly in the greenhouse heating cost guide.
• Permits and setbacks. A permanent glasshouse on a masonry base is exactly the kind of structure that can need a permit or trip a setback or HOA rule, and finding out after ordering is the expensive version. Check whether you need a permit before the design visit, not after.
• Lead time. Alitex does not publish one. Every structure is made to order, so ask for the current figure in writing when you get the quote.

The lifetime guarantee, read carefully

Alitex backs the aluminium frame with what it calls a lifetime guarantee, and the definition is printed: 25 years or the lifetime of the purchaser, whichever is longer. The paint finish carries 10 years, conditional on washing the structure once a year and sealing any paint chips within three months. Doors and bonded glazing bars carry five years. The FAQ gives Bayliss vent openers two years, while the guarantee page groups vent openers with one-year accessories, so confirm that term in the contract.

Two things to read twice. First, all of these guarantees are personal and non-transferable, in Alitex's own words. If you sell the house, the guarantee does not follow the greenhouse, exactly as with Hartley. Second, Alitex's own pages currently disagree about building works: the guarantee page says brickwork by their team is covered for one year, while the FAQ says ten. That is the kind of ambiguity you resolve before signing, in writing, not after a wall cracks.

On the substance, the cover is the strongest paper in the industry alongside Hartley's 30-year structural guarantee, on a frame that is powder-coated aluminium with a thermally broken profile and 4mm low-e toughened glass. This is a structure genuinely built to outlast its guarantee.

Alitex money versus the alternatives

Two things that table shows. First, Alitex's pricing transparency is a real buyer advantage over Hartley: you know within a few hundred pounds what a Tatton costs before anyone visits your garden, while a Hartley number requires a sales conversation. Second, the step down to a Janssens is enormous in money and small in glass. What you give up is the made-to-measure build, the maker's own installation crew, and the guarantee depth, which is exactly what the premium buys. Whether that trade is worth it for you is a lane question, mapped across the best greenhouses roundup.

One brand that used to sit in this comparison no longer does: Gabriel Ash stopped producing new greenhouses in April 2026. If you are weighing remaining stock, read the Gabriel Ash cost and closure guide before treating its old prices as live.

Before the design visit

Five things to get in writing, so the published price becomes your finished number:

1. The base. The drawings, the spec, and a real quote for the brick base or dwarf wall, from Alitex's building-works service or your own builder, before you sign.
2. The installed total for your site. In the UK, confirm you are inside the mainland England and Wales installation zone. In the US, confirm your state is on the included list, and get the install quote if it is not.
3. The building-works guarantee term. Alitex's pages say both one year and ten. Ask which applies to your contract and get it in the paperwork.
4. The current lead time, order to handover, since none is published.
5. The accessory total. Benching, shading, and heating are priced openly, so have the full fitted number in front of you, not just the structure line.
6. The payment schedule. Alitex does not publish deposit or stage-payment terms, so have the schedule, and what triggers each payment, written into the quote.

Then add the heating and power lines from the real cost of a greenhouse, and you have a project number you can decide on. If it lands outside your comfort, the brand directory maps the credible makers in the lanes below.

Frequently Asked Questions

What is the cost of this greenhouse?

In the UK, the published National Trust Collection prices run from £19,500 for the Hidcote (2.6 x 3m) to £55,600 for the Ickworth (2.9 x 7.1m), including VAT, delivery, and installation in mainland England and Wales, with the brick base extra. In the US, the Kew Collection starts at $60,000, with the entry Capel at $61,500 including delivery and installation in 19 listed states. Bespoke designs are quoted individually and run higher. All figures are Alitex's own published prices as of August 2026.

My dream greenhouse 😍, I wonder how much it would cost to build something like this?

For the greenhouse itself, start with Alitex's published £19,500 to £55,600 UK range or its $60,000 US floor. Then add the site-specific lines that are not in the standard UK price: brick base, groundworks, power, water, heating, benching, shading, and any bespoke changes. Get those quotes before signing so the structure price becomes a real project budget.

I would love an Alitex greenhouse, but since I'm not made of gold, I will build it myself.

You are paying for a hand-built, made-to-measure aluminium structure with 4mm low-e toughened glass, installation by the maker's own team, a frame guaranteed for 25 years or your lifetime, and the National Trust and Kew design heritage. Owners on gardening forums put it plainly: the prices make your eyes water, and the structures earn their reputation. If you will own the house for decades and want the glasshouse done once, it is a defensible buy. If your real need is growing space, a Janssens kit or a top-end Palram grows the same plants for a fifth of the money.

Has anyone done a comparison of these two Victorian structures and if so what does MSU or anyone else consider the better of the two?

For Alitex versus Hartley Botanic, there is no universal winner. Alitex gives you published standard-model prices and Hartley does not. Both sell premium British aluminium glasshouses with deep guarantees, and both require a project-specific comparison of base work, installation, service, and exclusions. Use the same written scope for both quotes, then read the full Hartley Botanic vs Alitex comparison.

Found the greenhouse of my dreams on Facebook marketplace and I fear I will forever grieve for it

Used and ex-display Alitex structures surface rarely, and the economics are tricky. You arrange dismantling, transport, replacement glass, and reassembly yourself, and the non-transferable guarantee does not follow the structure. Price that full relocation before committing, compare it with a smaller new model, and treat the used structure as guarantee-free.
