Chartered Certified Accountants · Harrow & Slough
We set out to build the practice that owner-managed businesses stay with for decades — not because moving is difficult, but because the relationship keeps earning its place.
A qualified accountant on every file. Technology doing the repetitive work, so our time goes into the judgement calls. And advice given straight, even when it is not what you were hoping to hear.
“Quality service at a reasonable fee”
About the practice
RAS Accountants & Business Advisors is led by Raheel Hasan, FCCA, who brings 17+ years of professional accounting experience across audit, tax and advisory work in UK practice.
The firm was built around five commitments, and they are not decoration. Excellence is the baseline: accounts, returns and audit files prepared to the standard of a large practice, because that is where the standard was learned. Long-term relationships are the point of the exercise — we would rather be the firm you call before a decision than the one tidying up afterwards.
Commercial candour means you get the straight answer, including the one you were not hoping for. Being future-focused means planning around where your business is heading rather than reporting on where it has already been. And being tech-driven — cloud ledgers, sensible automation and the discipline to keep them tidy — is what buys back the time to do the first four properly.
The result is the dedicated, one-to-one attention of a boutique practice, combined with the strategic insight of a large firm.
Meet the teamFive commitments that shape how we work, and how we expect to be judged.
Every set of accounts, every return and every audit file is prepared to the standard expected in a large practice, because that is where the standard was learned. Technical rigour does not scale down with the size of the engagement.
We are not interested in one-off transactions. We want to be the firm you call before you make the decision rather than after it, and we intend to still be that firm in ten years’ time.
Straight answers in plain language. If a plan carries risk, you will hear about it. If something is not in your interest, we will say so, even when staying quiet would be the easier course.
Tax and structure are forward-looking problems. We plan around where your business is heading, not simply report on where it has already been, so opportunities are identified while there is still time to act on them.
We work in the cloud — Xero, Sage, QuickBooks — and automate the repetitive so that your time, and ours, goes into the judgement calls. Technology has been part of this practice from the outset, not an afterthought bolted on later.

Raheel founded RAS Accountants & Business Advisors after more than 17 years in UK practice, spanning audit, statutory accounts, tax and advisory work for owner-managed businesses.

His client experience spans property, retail, professional services, healthcare and manufacturing, including companies with complex group structures. He brings a strong technical streak to the work, combining cloud platforms such as Xero, Sage and QuickBooks with today's AI tools to automate routine compliance — because efficient compliance is what creates the room for genuine advice.
