The Lounge

The No1 Lounge at T3 reopened in April 2025 following a closure for redevelopment, emerging alongside the brand-new Clubrooms space that now occupies part of the original floor. The refresh has updated the servery and common areas while retaining the core No1 format: a single main lounge space with a complimentary food and drink offer, open to all passengers on a Priority Pass or cash basis. The redesign gave up the former shower and spa area to Clubrooms — meaning No1 T3 no longer has shower facilities, which was a feature of the previous incarnation.

The lounge sits on the first floor of the Lounge F complex, directly above the BA Galleries lounges. It is a materially different environment from the airline lounges below — more casual, more varied in its passenger mix, and open to anyone regardless of airline or cabin. It shares the floor with Clubrooms, which is along the corridor to the right of the lift — the two lounges serve the same building but are separate products with separate reception desks.

Layout and Seating

The refreshed space is a single open-plan room with a mix of seating types — sofas and low tables for casual visits, higher stools and ledge seating along the walls for working, and standard dining tables near the food counter. The layout is functional rather than distinctive, in contrast to Clubrooms next door. Natural light is limited — the first-floor position above an internal corridor means window aspects are restricted, and the room does not have the apron views available from the Orangery in Clubrooms. It is a comfortable space to sit for an hour before a flight; it is not a room designed to make you want to linger.

Food and Drink

Food is served from a self-serve counter rather than at the table — the key operational difference from Clubrooms. Hot and cold options are available throughout the day, rotating between breakfast, lunch and dinner formats. The standard No1 menu covers eggs and pastries in the morning, sandwiches and hot mains through the day. Vegetarian options are always available. The quality is reliable and consistently middle-of-the-road — adequate for a pre-flight stop, not a reason to arrive early.

The bar is the more remarked-upon element. Complimentary wines, beers and spirits are self-serve, and the cocktail programme has drawn specific praise from reviewers as a cut above what most Priority Pass lounges at Heathrow offer. Champagne and sparkling wine are available at a surcharge rather than included. Coffee is self-serve from a machine. The overall drinks offer is the strongest argument for No1 over a generic contract lounge — and, for a short visit with a cocktail and a plate of food, the value relative to the terminal’s food-and-beverage alternatives is clear.

Dress Code

Smart casual is required across all No1 Lounges group properties. Sportswear, beachwear and overly casual clothing are not permitted. The standard is applied at the door — clean trousers, a collared shirt or equivalent will not cause any issue. The same policy applies at Clubrooms next door.

No1 vs Clubrooms

No1 and Clubrooms occupy the same floor of the same building and serve much of the same passenger population. The core difference is service style and price. No1 is free on Priority Pass with a self-serve food counter and drinks bar. Clubrooms charges a £15 supplement and delivers à la carte table service, a more curated food menu, complimentary cocktails brought to the table, a no-under-12s policy, and the Orangery space with apron views. For a short visit or a quick stop before the gate, No1 is the right call. For a longer stay or a proper pre-departure meal, the £15 Clubrooms supplement is straightforward to justify.

No1 at T3 vs No1 at Other Airports

The No1 Lounge is a network brand with sites across the UK including Heathrow T2, Gatwick North and South, Birmingham, Edinburgh and others. The T3 location is consistent with the brand standard — the same format, the same access terms, the same level of finish. The April 2025 redevelopment has brought the T3 space up to the current No1 specification, removing the dated shower and spa area that had become a weak point. Passengers who know the No1 Lounge from Gatwick or Birmingham will find T3 familiar; the room is broadly comparable in atmosphere and quality. The main T3-specific advantage is the proximity to Clubrooms as an easy upgrade option if you arrive and want something better.

Getting In

Straightforward on Priority Pass — card and boarding pass at reception. Walk-in access is available but pre-booking is recommended during peak morning and late-afternoon windows, particularly on busy weekends. My Lounge, which opened in July 2025 further into the T3 departure area at Lounge D, is the other free Priority Pass option in the terminal. Pre-booking via no1lounges.com guarantees entry for a small fee above the standard access cost.
