When Wellington organized his troops into numbered divisions for the Peninsular War, the component brigades were named for the commanding officer. For the Hundred Days Campaign, he numbered his British infantry brigades in a single sequence, 1st to 10th. The 7th Brigade formed part of the 7th Division under the command of Major-general Kenneth MacKenzie. It consisted of: It was assigned to garrison duty and so played no part in the Battle of Waterloo.

World War I
At the outbreak of the First World War, the 7th Brigade was a regular army formation stationed at Tidworth and assigned to the 3rd Division. It mobilized with the division, crossed to France between 11 and 16 August, concentrated around Aulnoye and Avesnes, and moved forward on 21 August 1914. Other than a brief period when it was reorganized in England in 1918, the brigade served with the 3rd and 25th Divisions on the Western Front throughout the war.

3rd Division
With the 3rd Division, the brigade took part in a large number of actions in 1914: the Battle of Mons (23 and 24 August) and subsequent retreat (24 August – 5 September) including the Action of Solesmes and the Battle of Le Cateau. It then took part in the First Battle of the Marne (6 – 9 September) and the Race to the Sea: First Battle of the Aisne (13 – 20 September), and the battles of La Bassée (10 October – 2 November), Messines (31 October – 2 November), Armentières (1 and 2 November) culminating in the First Battle of Ypres (5 – 21 November), notably the Battle of Nonne Bosschen (11 November). 1915 was relatively quieter, but included the First Attack on Bellewaarde (16 June), Hooge (19 July) and the Second Attack on Bellewaarde (25 September).

While with the 3rd Division, the brigade commanded
 * 3rd Battalion, Worcestershire Regiment
 * 2nd Battalion, South Lancashire Regiment
 * 1st Battalion, Wiltshire Regiment

25th Division
On 18 October 1915, 7th Brigade was posted to the 25th Division in exchange for 76th Brigade as part of a policy of "stiffening" New Army Divisions with regular units. Once there, it was extensively reorganized on 26 October: On 12 January 1916, the brigade formed the 7th Machine Gun Company and was joined by the 7th Trench Mortar Battery on 18 June 1916.
 * 2nd Battalion, Royal Irish Rifles transferred to 74th Brigade in exchange for 10th (Service) Battalion, Cheshire Regiment
 * 2nd Battalion, South Lancashire Regiment transferred to 75th Brigade in exchange for 8th (Service) Battalion, Loyal North Lancashire Regiment

The brigade saw action in 1916 defending against the German attack on the Vimy Ridge (21 May) but particularly in the Battle of the Somme, including the battles of Albert (3 – 13 July), Bazentin Ridge (14 – 16 July), Pozières Ridge (18 August – 3 September including the fighting for Mouquet Farm on 3 September) and Ancre Heights (1 – 22 October including the capture of the Stuff Redoubt and the Regina Trench).

On 1 March, the 7th Machine Gun Company joined the 74th, 75th and (divisional) 195th Machine Gun Companies in the 25th Battalion, Machine Gun Corps. Due to a shortage of manpower, all British divisions on the Western Front were reduced from a 12-battalion to a 9-battalion basis in February 1918. As a consequence, 7th Brigade was reduced from four to three battalions. Almost immediately, the German Spring Offensive fell upon the division. The 25th Division was remarkably unlucky; having faced the first German onslaught at the First Battles of the Somme (21 – 25 March), it was moved north to refit, where it faced the second offensive in the Battles of the Lys (9 – 29 April). It was once again moved south to a quite part of the line where it was attacked for the third time in the Battle of the Aisne (27 May – 6 June).

Due to losses sustained, the division was withdrawn from the line and the brigades were reduced to cadre. The divisional and brigade HQs returned to England with 10th Cheshires and 10 other Training Cadre (T.C.) battalions, arriving on 30 June. For the 7th Brigade this meant: The brigade arrived in England on 30 June and went to Mytchett Camp, Aldershot. Soon after, the T.C. battalions left the brigade (10th Cheshires and 8th Leicesters on 7 July, 13th East Surreys on 16 July) for Eastern Command where they were reformed.

 * 13th (Service) Battalion, East Surrey Regiment joined as a T.C. from 119th Brigade, 40th Division at Boulogne on 30 June and went to England with the brigade

The brigade HQ returned to France with 25th Division HQ on 15 September, arriving at St. Riquier near Abbeville the next day. Units left behind in France (artillery, engineers, signals, pioneers, machine gunners, etc.) rejoined the division between then and 19 October. The brigade was reformed on 16 September with battalions withdrawn from the Italian Front: Thereafter the brigade took part in the Final Advance to Victory, notably in the Battles of the Hindenburg Line – Battle of the Beaurevoir Line (4 and 5 October), Battle of Cambrai (8 and 9 October), and Pursuit to the Selle (9 – 11 October) – and the Final Advance in Picardy – Battle of the Selle (17 – 25 October) and Battle of the Sambre (4 November).
