About Blackstone Accountancy

Accountancy you can rely on, backed by experience and personal service

At Blackstone Accountancy, we provide professional accounting, tax and payroll services that are accurate, compliant and easy to work with. We help UK businesses and individuals stay on top of their finances, reduce stress and make better-informed decisions.

Based in London, we work with small businesses, contractors, freelancers, locums and individuals who want their accounts handled properly, with clear processes, responsive support and attention to detail.

Who We Are

Blackstone Accountancy is a UK-based professional firm providing accounting, taxation, payroll and business advisory services across a range of sectors. Our approach is simple: understand your business, build a reliable process around it and deliver consistent, high-quality work throughout the year.
We know that missed deadlines or inaccurate records can lead to HMRC penalties and unnecessary stress. That’s why we focus on accuracy, structure and clear communication, so your compliance runs smoothly in the background.

What we stand for

Accuracy without shortcuts

Accounts, tax calculations and submissions are prepared carefully, with checks built into every stage of the process.

Compliance and peace of mind

We keep up to date with HMRC and Companies House requirements, including legislation such as IR35 and Making Tax Digital, so you stay compliant throughout the year.

Clear communication

We believe accountancy works best when expectations are clear. You’ll always know what we need, when we need it and when your returns will be filed.

Personal, responsive support

You’re not dealing with a call centre. We build long-term working relationships, so your affairs are looked after by people who understand your business.

A service that feels in-house

Our goal is to feel like part of your team, not an outside firm. We take time to understand how your business works, anticipate changes and respond quickly when questions arise.

By combining structured processes with personal support, we help clients reduce risk, stay tax-efficient and free up time to focus on what they do best.
