Acton Swimming Club was formed in 1904 when Acton Baths were opened. The opening ceremony was held in the Second Class Baths (now the small pool) under the auspices of the newly formed Acton Swimming Club.

Councillor Boissonado declared the Baths open with young Master Harry F Hancock (7 years old) of Acton Swimming Club swimming two lengths. This was followed by Acton's first race, the 4 x 1 length front crawl relay against Napier Swimming Club, which Acton won.

Acton continued to do well throughout the 20s when Acton Ladies SC joined Acton SC (Gentlemen) as one club.

During the Second World War Acton SC had to close down. It re-opened in 1951. In 1953 Mr and Mrs Matthews joined Acton SC and the swimmers began training twice a week. The Club Championship was also devised with cups being presented by friends or organisations connected to the club.

By 1966 Acton had become a very fashionable and successful club. In that year the Club won 12 galas in a row including one in Belgium. During this time they were the first club to win the Winter League without losing a gala. Many of their swimmers went on to become Middlesex Champions.

In 1967 the pool closed down and Acton had to train at Old Ealing Baths. Many of its star swimmers left and moved to Heston SC or the newly formed Northolt SC in the new Northolt Pool. The club returned to Acton Baths in 1968 and continued to struggle throughout the 70s. They had some success in local competitions thanks to Mr Meeney, Miss Tracey Fryer and Mr Conway all working along with the Committee to keep the club afloat.

By the early 1980s Pat Arnell had joined Acton and started to improve the club by introducing a training structure and more sessions. Club records began to tumble, Pat also introduced the Masters Swimming section to Acton SC which to date has been very successful. Many of Pat's swimmers reached Middlesex finals. The pool was then closed down again for refurbishment in the late 1980s for two years.

The Club returned with 80 members in 1982. John Bell then joined as Head Coach, with help from Ken Adey. By 1994 the Club was about to close down through lack of members. An extraordinary General Meeting was held and volunteers came forward to help. Within four years Acton had their first Middlesex Champions for over 20 years. In 1998 Holly Mills won four individual Middlesex titles, the 50m butterfly, 50m backstroke, 50 m breaststroke and 100m Individual Medley, and together with Cerys Fry, Jessica Trevelick and Maya Susuki also won gold in the Girls Medley Relay Team.

In 1999, with seven training sessions a week, Acton continued to improve. The Club had 14 Middlesex Championship finalists, with Holly Mills and Joseph Naud both winning Middlesex titles. The Club also won 6 Club team trophies and had two runners up spots in the Milton Keynes Junior Leagues and the North London Junior League which promoted them to Division 1.

Ken Adey was appointed Head Coach in 2000 and saw Acton retain the Epping Forest Junior Open Trophy as well as winning another team trophy in the North London Junior League where they finished 3^rd. The Club Swimmers continued to do well in the North London Graded League and have improved their position in the National Speedo League where they finished 22nd in Division 2 London. In the Milton Keynes Junior League Division 1 - competing for the first time against some of Britain's top junior clubs - they found it tough going, finished third from bottom and were relegated back to Division 2. In June, in the Masters Swimming section, ex-international swimmer Ian Hubble was appointed Masters coach.

Acton had another successful year in 2001 winning the Milton Keynes Division 2 League, their first League title since 1966. There was disappointment that the North London Junior League ended as Acton's youngsters looked as if they might do well in this League. The Club went on to win the Northolt Invitation Gala and an Inter Club Gala at Acton Baths, and finished 2nd in the Allan Davies Trophy Gala. In the North London Graded League Acton came 2nd in two galas and 3rd in another, finishing in 5th place overall. In the National Speedo League Division 2 the club had their best year to date finishing 20th with a second place at Potters bar. In the Middlesex Championships Acton had 19 top eight places, a new club record, with 6 bronzes from Gemma Porter and Lucy Burch, and Tayo Coker collecting 1 relay and 3 individual bronze medals.

In 2002 Acton held its 50th Anniversary Gala after having been reformed in 1951 following the Second World War. The gala was won by Teddington with Acton finishing 2nd and Anaconda 3rd. In the Middlesex Development Autumn and Winter Meets Acton's youngsters won 22 gold medals, 17 silvers, 10 bronzes, 38 speeding tickets and had a total of 84 finalists. Jessamy Hardie and Tayo Coker reached the National Finals of the Biathlon Championships, where Jessamy finished 26th and Tayo finished 36th. In the North London Graded League Acton finished 4th overall, winning the gala at Gurnell, and in the National Speedo League the Club finished 21st with a 2nd place at Borhamwood. In the Milton Keynes Junior League Acton's youngsters finished in a creditable 12th position overall with a 2nd place in the final round at Luton.

The Masters Swimming section continued to grow and by the end of 2002 had 30 members. Malcolm Munro had a fantastic year under the guidance of coach Ian Hubble. At the Crystal Palace Long Course Meet in June Malcolm became the 2002 British Masters Champion in the 50m Breaststroke and 100m Breaststroke in the 55-59 age group, and in July at the Barnet Copthall Masters Distance Swim Meet Malcolm broke 3 County records in the 55-59 age group when winning the 100m Breaststroke, 200m Breaststroke and 200m Backstroke.

The Club had another record breaking year in 2003. In the London Graded League Acton finished in a creditable 4th place. Up to round 4 Acton was in 1st place but fell away in the second half of the year. The series included 2 gala wins at Kensington and Northolt. Acton youngsters finished in 12th in the Milton Keynes Junior League Division 1 with a 4th place in the first round and 2nd place at Northampton. In the third round Acton finished 4th behind Maidenhead and just 42 points behind Ealing. In the National Speedo League London Division 2 Acton finished 15th with 2 fifth places and 1 fourth place. The club also competed in 3 Inter Club Galas finishing 3rd at Northolt, 4th at Teddington and 1st at Forward Hillingdon in a very exciting gala. In the Middlesex Age Groups Acton collected a record 34 top eight places, with 3 golds won by Melko Coker, 1 gold by Tayo Coker and 1 bronze by Jessica Clark. Melko also won 4 silvers and 1 bronze to take the top boy for his age in the Bagcats awards. Jessamy Hardie finished 4th in the 50m and 200m breaststroke and qualified for the Southern Counties where she finished in 11th in the South of England. In the Masters Section Malcolm Munro had another great year by breaking the Middlesex County 200m backstroke record in October at the Basingstoke Masters Meet.

In 2004 Acton Swimming Club celebrate their centenary year and continue to break even more records. In the London Graded League the club has competed in four galas to date, finishing 5th in three galas, winning the gala at Waltham Forest and are currently in 3rd place overall. The club have also swum in three inter-club galas against Brent Dolphins and Feltham and won all three. In the Milton Keynes Junior League Division 1 Acton came 6th in the first round, 3rd in the second round and are currently in 15th place.

In the Club’s Centenary Gala Acton won against Teddington and Ealing (Northolt Phoenix) SC on the 12th June, 100 years to the date that Acton swam their first race. On June 26th Acton celebrated in style by holding their Centenary Party at the Old Actonians Sport Club (photos on web site).
