The newcomers are Caledonia Storm (Caledonia's second string), Rotherham Metro, who return to BWPL after a short break, Spalding, Warwick and Watford Saxons (Watford's second team).
South Derby and University of Bristol men's teams have both withdrawn. So Grantham and Bedford, who finished fourth and fifth in Championship 4 this season, move up to fill vacancies in Division 4. Competing alongside the newcomers in Division 5 will be Leeds, Sheffield Dolphins and Tyldesley.
The women's Division 3 line-up was confirmed following last weekend's qualification tournament as: Birmingham, English Roses, Leeds Hammerheads, Liverpool Water Beatles, Polytechnic, Sheffield Stingrays, Southampton and Sunderland.
