If you've spent any time searching for extractor fans, MVHR units or commercial ventilation equipment online, you'll know the market is cluttered with generalist electrical retailers who stock three models and call it a range. Efans UK takes a different approach: they specialise entirely in heating and ventilation, carry stock from proper manufacturers, and promise free next-day delivery across the UK. That's a meaningful offer when you're a builder waiting on a job or a homeowner with a bathroom ceiling half-open.
This review covers the full picture — what they stock, what they charge, where they fall short, and whether the specialist positioning actually translates into a better buying experience. We've looked at their product range, pricing, delivery promise and customer support claims so you don't have to work it out from scratch.
The short answer: for anyone who knows what they need and wants it fast at a fair price, Efans UK is a solid choice. If you're still at the "what on earth is an MVHR unit?" stage, read on — we'll cover that too.
About Efans UK
Efans UK is a specialist online retailer focused exclusively on heating and ventilation products for domestic and commercial buildings. Unlike a Screwfix or a Toolstation, which carry ventilation as one aisle among dozens, Efans has built their entire catalogue around fans, ducting, heat recovery and air movement. That focus matters: the staff understand the products, the range goes deeper, and the technical advice is more likely to be useful than a generic helpline reading off a spec sheet.
They operate as a trade-friendly business that also sells direct to homeowners. This dual audience shapes how they communicate — you'll find technical specifications alongside plain-English guidance, which is genuinely useful if you're a first-time buyer trying to understand the difference between a single-room heat recovery unit and a whole-house MVHR system.
Their market position sits between the big-box generalists (cheaper on headline price, weaker on range and advice) and specialist HVAC trade suppliers (stronger on technical depth, but often slower, pricier and less accessible to the public). Efans tries to split that difference — and largely succeeds.

What Efans UK Offers
The Efans UK product range covers the full ventilation stack, from the unit that moves the air to the ductwork and grilles that get it where it needs to go. Key categories include:
- MVHR units — whole-house mechanical ventilation with heat recovery, from entry-level domestic units to larger commercial-grade systems
- Extractor fans — bathroom, kitchen and utility room fans from established manufacturers, covering both standard and low-energy models
- Commercial fans — inline, centrifugal and axial fans for larger buildings, plant rooms and industrial spaces
- Heat recovery units — single-room decentralised units for retrofit projects where whole-house ducting isn't viable
- Weather louvres — including made-to-order custom sizes, which is genuinely unusual for an online retailer
- Ducting and grilles — rigid and flexible ducting, bends, reducers and decorative grilles to complete an installation
On price, the range sits at the competitive end of the market — not the cheapest you'll find on a price-comparison site, but consistently fair for branded equipment with next-day delivery included. Most domestic extractor fans sit in the £20–£120 range; MVHR units run from roughly £400 into the thousands depending on capacity and specification. Custom louvres are priced on application.
Featured Product: MVHR Units
Mechanical ventilation with heat recovery — MVHR — is the standout product category at Efans UK, and the one where their specialist positioning makes the biggest practical difference.
An MVHR system extracts stale, moist air from wet rooms (bathrooms, kitchens, utility rooms) and simultaneously draws fresh air in from outside, passing both airstreams through a heat exchanger in the process. The outgoing warm air heats the incoming cold air before it's distributed around the house. In a well-insulated home, this means you're ventilating properly without haemorrhaging heat through an open window — which matters considerably more now that building regulations and energy costs are both pushing in the same direction.
Efans stocks MVHR units suitable for everything from a two-bedroom flat to a large detached house, with models from manufacturers who actually specialise in this equipment rather than bolting a heat exchanger onto a generic fan housing. Efficiency ratings, air flow volumes (measured in m³/h) and noise levels (dB) are all listed clearly in the product specs — useful when you're trying to match a unit to a building's calculated ventilation requirement under Part F of the Building Regulations.
The made-to-order element is worth flagging here too. MVHR installations often require weather louvres sized to fit specific wall or roof penetrations. Efans can supply custom louvres to order — something most online retailers simply can't do, and which normally means a time-consuming detour to a fabrication specialist.
Who is this for? Primarily self-builders, architects specifying new builds, and contractors retrofitting ventilation into existing properties. It's not a casual purchase — an MVHR unit is a considered investment that typically requires professional installation and commissioning. But if you're in that market, check the current range and pricing at Efans UK before going to a trade-only supplier. The prices are competitive and the delivery speed is a genuine advantage on a build programme.
Who should skip the MVHR range? Anyone who just needs a bathroom fan for a straightforward extract-only installation. That's a different product entirely, and Efans stocks those too — you don't need to go near the MVHR section.
Pros and Cons of Efans UK
Pros
- Free next-day UK delivery — included as standard, not as a paid upgrade. On a building project, this is worth real money in avoided delays.
- Genuine specialist range — ducting, grilles, louvres and accessories are stocked alongside the fans, so you can complete an order in one place rather than cobbling together parts from three suppliers.
- Made-to-order custom louvres — unusual for an online retailer and genuinely useful for non-standard installations.
- Onsite engineer support — the availability of technical advice from people who understand ventilation systems, not just a generic customer service script, is a meaningful differentiator.
- Competitive pricing on branded stock — prices are fair for equipment from recognised manufacturers, and the free delivery makes the total cost of order more competitive than it first appears against rivals who charge £8–£15 for shipping.
Cons
- No physical showroom or trade counter — everything is online. If you want to see a unit before you buy, or need something urgently on a Saturday morning, you're out of luck.
- Specialist focus cuts both ways — if you need ventilation equipment alongside other building materials or electrical components, you'll still need a second supplier. Efans doesn't do plumbing fittings or general electrical.
- Custom louvre lead times are unclear upfront — made-to-order products naturally take longer than off-the-shelf stock, but the site doesn't always make lead times obvious before you enquire. Worth checking before you commit if you're on a tight programme.

Who Is Efans UK For?
Efans UK is best suited to three types of buyer: the self-builder or renovator who has done their research and knows what specification they need; the small contractor or sole-trader installer who wants trade-quality kit at a fair price without a trade account; and the homeowner replacing a like-for-like extractor fan who wants the job done tomorrow.
The free next-day delivery and onsite technical support make it particularly well-suited to anyone on a build schedule where delays cost money. The depth of range — ducting, grilles, louvres and accessories all in one place — also means fewer split orders and fewer coordination headaches.
It's less well-suited to buyers who are still at the research stage and need hand-holding through the specification process, or to anyone who wants to physically inspect a product before purchasing. It's also not the right call if you need ventilation equipment as part of a broader materials order — you'll save time using a general merchant for that.
On value for money in the UK context: with free next-day delivery baked in and prices that hold up against the generalist retailers, Efans UK offers genuine value for the buyer who knows what they want.
FAQ
Is Efans UK legit?
Yes, Efans UK is a legitimate specialist online retailer selling branded heating and ventilation equipment. They stock products from recognised manufacturers and offer free next-day UK delivery with technical support. As with any online purchase, check your statutory rights under the Consumer Contracts Regulations 2013, which give you 14 days to return most online orders.
Does Efans UK offer free delivery?
Yes — free next-day delivery across the UK is included as standard on orders from Efans UK, with no minimum spend threshold advertised. This is one of their headline selling points and makes them genuinely competitive against suppliers who charge separately for shipping on heavy or bulky items like fans and ducting.
Can Efans UK supply custom or non-standard sizes?
Yes, for weather louvres specifically, Efans UK offers made-to-order custom sizes — which is unusual for an online retailer in this category. For other products such as ducting and grilles, the range covers standard sizes. If you have a non-standard requirement, contact them directly before ordering to confirm availability and lead time.
Does Efans UK sell to the public, or is it trade only?
Efans UK sells to both trade and domestic customers. You don't need a trade account to buy. The site is accessible to homeowners, and the product listings include enough technical detail to be useful to both a professional installer and an informed DIY buyer replacing a fan in their own home.
How do I know which extractor fan or MVHR unit to buy from Efans UK?
Efans UK offers onsite engineer support — you can contact them with your project details and get technical advice before you order. For MVHR units, you'll need to know your floor area and the number of wet rooms; for extractor fans, the room volume and any building regulations requirements (Part F) will determine the minimum extract rate. Their team can help you match a product to those figures.
Our Verdict
Efans UK does one thing and does it properly: heating and ventilation equipment, in stock, delivered free the next day, with people available who actually understand what they're selling. For a contractor fitting out a new build, a self-builder specifying an MVHR system, or a homeowner who just needs a bathroom fan by tomorrow, that combination is hard to beat at the price point.
The limitations are real but narrow. No physical presence, no broader product range, and some opacity around custom lead times. None of those matter if ventilation is what you need.
If you're buying extractor fans, MVHR units, ducting or commercial ventilation equipment in the UK in 2026, browse the full range at Efans UK before you default to a generalist retailer. The specialist depth and free next-day delivery make it the smarter starting point for most buyers in this category.
We rate Efans UK 4.0 out of 5.
