The Leyland National was built with integral, modular construction and a rear engine. All components were designed for ease of construction and replacement. Until 1978, it was always built with a roof mounted pod at the rear, housing the heating equipment, which consequently blew warm air out at roof level. At first the pod was almost the length of a bay and appeared designed to give a Trans-Atlantic feel. In 1976 a new shorter version of the roof pod was introduced along with the battery being relocated to the front under the cab. The Leyland National was available in three lengths, the majority being 10.3m and 11.3m. It was easy to spot the longer ones as its main side windows were all the same length, on the shorter models the windows were shorter except for one in the middle (where the exit doors were on dual door variants) which was the same length as on the longer models. The third length was 10.9m, specially produced for Australian operators due to stringent axle weight limits. This used the front section of the 11.3 metre bus and the rear section of the 10.3 metre bus. One 10.9 metre bus (the prototype) was sold to a Scottish operator (Rennies of Dunfermline) and was fitted out to dual purpose specification for use on express services.

The Leyland National was a simple design: all parts could be replaced. Some operators, like London Transport, bought dual door models, and then later configured some of them to single door. This was helped by the design of the body, the fact that parts were inter-changeable and that the bus was constructed using Avdelok rivets, specially designed for the National, instead of the more usual pop rivets screws or welding.

The earlier vehicles were only available in a limited number of standard colours, e.g. dark red, light red, dark green, to try to match but simplify existing operators' liveries. This just predated the decision by the National Bus Company to standardise on two colours: poppy red and leaf green. The timing was such that several vehicles were delivered in dark red paint to Ribble, who repainted them poppy red before entry into service. At London Transport's insistence, London bus red was added to the colour card, and their fleet eventually amounted to over 500 examples acquired between 1973 and 1980.

In 1978, Leyland brought out a simplified model (10351B/1R) intended to replace the Bristol LH which had been in production since 1967 and was a type popular in NBC companies for rural routes. It was available in a single length (10.3m) and had a revised interior that had minimal lighting and without the rear roof-mounted heating unit in previous models. Heating was under the seats, and was basic but effective. These vehicles were lighter, and this characteristic and the lower cost helped make extra sales. London Country bought quite a number of these, which other operators snapped up when London Country was broken up.

The National 2 was introduced in 1979. It differed from its predecessor mainly by having a wider choice of engines, along with a new nose moulding giving it a more bulbous look and a grille to cool the new front-mounted radiator, and a revised rear end with new lights and a different engine door.[2][3]

The first was delivered in March 1972 to Cumberland Motor Services (ERM35K) and the bus quickly became a common sight on British roads.[4] Although developed for the National Bus Company (whose subsidiaries effectively had to purchase it), it was also bought by the Scottish Bus Group subsidiaries,[5] London Transport,[6] SELNEC[7] and British Airways[8] (which chose the 3 door version) and other operators.

The export version of the Leyland National was constructed in the standard way, although some were what might be called a hybrid, consisting of longer windows up to the rear axle and shorter ones after. This resulted in a 10.9 metre bus as opposed to either a 10.3 or 11.3 metre version.

Given the design it was very easy to produce left hand drive vehicles and these were used as a way of generating orders.

However, the Leyland National was not particularly successful in the export market - the largest export order of 450 was to Caracas, Venezuela, in 1975–76. Around 125 Leyland Nationals were shipped to Kingston, Jamaica, between 1972 and 1974 to be operated by the Jamaica Omnibus Service, a subsidiary of the British Electric Traction company. Forty were exported to Trinidad and Tobago for use by the National Bus Company.

Nederlandse Spoorwegen in the Netherlands purchased 25, but problems with windscreen glare resulted in the windscreens being removed and a different version being fitted.[12] In France, Dijon purchased six, while St Étienne Municipality purchased 20.[13]

Singapore Bus Services received a single 11.6m dual door Leyland National 2 in February 1981 which would mostly work on bus route 143 as SBS6820L until its withdrawal in 1983, after which it was exported to Australia.[14]

In Australia, ACTION purchased 70 Nationals in 1974–75, 16 being fully assembled in England and 54 in Australia. Some were repowered with MAN engines.[15] In 1975, Brisbane City Council purchased seven[16] while the Melbourne & Metropolitan Tramways Board purchased 30.[17]

The Metropolitan Transport Trust purchased 63 in 1975–76 for use in Hobart. These were all 10.3 metre units, however one was rejected and its replacement was a 10.9 metre unit.[18] Surfside Buslines were the largest Australian private bus operator with a fleet of 38 purchased new and second-hand.[19]

The chassis of the Leyland National was also sold as the Leyland B21 in limited numbers to overseas operators.[20]

In all over 7,000 Leyland Nationals were built.[21][22] It was replaced by the Leyland Lynx.

Very few Nationals remain in service, the last major operator was Chase Bus Services, Chasetown who sold the operations to Arriva Midlands and ceased operating as a separate entity on 28 April 2007.[23] Notably all but two retained Leyland 510 engines to the end.

Over 100 Leyland Nationals have been preserved.[24] The Workington factory has closed, though part of the building now forms part of a Stobart Group depot.

In 1980, some underfloor-engined articulated buses with bodywork derived from the Leyland National were assembled by Charles H Roe.[25][26]

In the 1980s, Leyland National bus components were also used to build the following classes of railbuses for British Rail:

• Class 141
• Class 142
• Class 155 (many later converted to Class 153s)

Despite the best intentions, the front end of the Leyland National was not considered substantial enough to allow for a standard bus front end to be used on train carriages. The body was very similar to a National, the components used were identical but the configuration was to a different format.
