About

A specialist practice, not a body shop.

Built around a simple idea: on a rail programme, assurance is the function that decides whether the railway opens on the date the client promised.

Sidharth Dawar
Director & Principal Assurance Consultant

Two decades holding independent safety authority on some of the world's largest rail programmes — from Crossrail's integration to authorising a $10bn metro with a national regulator.

Who we are

Independence, depth, and a regulatory track record.

Get assurance right and it's a source of certainty; get it wrong and it's the thing quietly holding everything up. We bring the independence, the technical depth and the regulatory experience to make safety evidence hold up — and we deliver it as clearly scoped work you can plan around, with associate capacity for larger engagements.

Integrated Assured Solutions works across metro, high-speed, mainline, freight and commuter rail, in the UK, the Gulf and internationally.

We run a quality management system built to ISO 9001:2015. It covers how we take on work, how every deliverable is reviewed before release, how we record and fix what goes wrong, and how we check our own performance each year. We are working with ISOQAR, a UKAS accredited certification body, towards certification; the Stage 1 assessment was completed in September 2026. Our quality policy is public.

Standards & credentials

Rigorous where the standards actually bite.

Deep working authority across the frameworks that govern rail safety — and the judgement to apply them proportionately.
