The short version
Arch Enclosures builds wide, arched aluminium and polycarbonate buildings over pools, in spans from 5 to 25 metres. It says it has over 40 years of experience in lightweight structures and sells direct, as a fixed price package covering design, manufacture and installation by its own engineers.
It also sells two other ranges. Its low enclosure pages name Aquacomet and its timber arch pages name Abri Sud, so those two appear to come from other makers.
Its product pages carry no prices. The only figures are general guide ranges in articles on its site, and those do not agree with each other.
What it costs
Arch’s product pages give no figures. It describes its offer as a “complete fixed price package” and, for its low range, says installation fees are included in the quotation and depend on location.
Articles published on its site between July and September 2026 do give guide figures. They are written about the market in general, not as quotes for Arch’s own buildings, and none is tied to a size:
| What the article describes | Guide figure |
|---|---|
| Bespoke aluminium enclosures, a modest domestic structure | From around £15,000 |
| Mid-range retractable aluminium enclosure, installed | £15,000 to £30,000 |
| Mid-height telescopic models, residential | £25,000 to £40,000 |
| High-level standing enclosures | From around £40,000, over £80,000 for large bespoke designs |
| Full commercial installations | Regularly over £60,000 |
The articles disagree on where prices start. One says entry-level systems start from around £10,000 to £15,000. Another says entry-level aluminium and polycarbonate systems start at around £3,000 to £6,000. None mentions VAT.
We also read three pages about Arch on other sites (its listing as an Abrisud partner, a business directory and a magazine feature). None gives a price.
What you get

Arch says each component “meets and often exceeds British and EU specifications” and that its tracks hold the building against strong winds. It gives no wind or snow figure for the aluminium Arch range. Its Timber Arch pages state a minimum of 100 km/h of wind and 45 kg of snow per square metre. It does say it will supply full drawings and calculations for planning consent.
Warranty
A 10 year factory guarantee on its Arch buildings, stated on the site and in the brochure. The terms are not set out.
The low range is different: 3 years on materials and manufacture, 5 years on SAN panels, 10 years on solid polycarbonate panels, and installation covered in the first year only. Those terms say the warranty lapses if snow is left to build up or in wind over 15 metres per second.
The company
The site names Arch Enclosures Ltd and gives a P.O. Box in Haywards Heath. It does not give a company number. The public register has Arch Enclosures Limited, number 07656970, incorporated on 3 June 2011, with its registered office in Littlehampton. We matched it by name.
On 1 October 2026 the register showed it as active, with accounts filed to 31 May 2025 and the next due by 28 February 2027. A second company, Arch Enclosures UK Ltd (17313922), was incorporated at the same address on 2 July 2026. We do not know which company a new contract would be with. Ask, and check that the name on your contract matches the one on the register.
What we could not find
- A price, or a price range, for an Arch building of a stated size.
- Load figures for wind or snow on the aluminium Arch range.
- The terms of the ten year guarantee.
- A company number on the website.
Questions worth asking
- Which company will I be contracting with?
- What would a building for my pool size cost, with VAT, and how does that sit against the guide figures in your articles?
- What are the wind and snow ratings for my span, and can I see the calculations?
- What does the ten year guarantee cover, and what does it exclude?
- For the low and timber ranges, who is the maker and who gives the warranty?
