Five Enviro 400 CBGs were ordered on 30 April 2016, becoming 701-705. The vehicles were the world’s first Euro 6 gas powered double deckers, and followed on from Scania & Alexander Dennis' development of the gas powered Enviro300 which had proven both economically sound and reliable. Gas tanks are installed under the staircase and rear seats instead of the roof pod used on the single-decker. Gas produces almost no particulates or hydrocarbons, almost zero carbon and 99% less nitrogen oxide than a diesel vehicle. The Natural Gas comes from a certified carbon neutral bio-methane source, mainly cow poo.

The interior features high back seating with black flat-cloth, at-seat USB charging sockets for mobile phones and tablets, a table area upstairs with a wireless ‘aircharge’ mobile and tablet charging pad, free superfast 4G Wi-Fi, wood effect flooring and next stop audio and visual customer information systems. The buses also feature two wheelchair bays as part of a trial for future specifications, allowing two wheelchair users to travel together.

701 was exhibited at the Coach and Bus Live show at the NEC in Birmingham from 1st to 3rd November 2016, and 703 was displayed in Broad Street as part of the official launch of the vehicles on 14 January 2017. All five were delivered to the Scania dealership in Thatcham in December where they were stored pending registration and taxation, apart from 704 which was brought to Reading for staff familiarisation, albeit still un-registered.

701 is seen below in Friar Street on 31st March 2017:

Pending delivery of 701-5, three diesel Scania N250 / ADL Enviro 400 MMCs were loaned from Scania in October 2016 pending delayed delivery of 701-5. The first arrived on 18th October, followed by the other two by 23rd and were allocated fleet numbers 775-77 following on from the Enviro 400 chassied Enviro 400 MMCs.

All three entered service on 24th October 2016 with Royal Blue logos on dealer white livery. This branding was removed in January following 701-5 entering service, with the vehicles acting as additional generic fleet vehicles until returning off loan. 776 was with Ipswich Buses by 21st February 2017, 775 remained in service until 19th March and 777 until 17th March, returning to Scania around 22nd March and passing directly to Borders Buses where they were joined by 776 from Ipswich.
