CHARTERED ACCOUNTANTS AND BUSINESS ADVISORS IN HARPENDEN

Large enough to meet your financial needs, small enough to know your name.

Who Are We

Cubed Consultancy is a firm of ICAEW chartered accountants in Harpenden, Hertfordshire, and is FCA-authorised for financial planning.

That means your tax position and your financial plan are built together, in the same conversation.

We work from Harpenden, with a London presence, for owner-managed businesses across Hertfordshire and the commuter belt — limited company directors, partnerships, sole traders, and families with property or investments alongside a business. We also act for professional sportspeople, entertainers and clients holding cryptoassets.

Before we talk numbers we talk about your business: where you are, where you’re heading, and what success actually looks like. Large enough to meet your financial needs, small enough to know your name.

Industries we know inside out

Construction

CIS returns, the VAT reverse charge, and retentions that sit unpaid for a year after the job finishes.

Retail

Margin by product line and channel, stock at the year end, and VAT across marketplaces and your own site.

Sports

Purse income, image rights, and planning for a career that may last ten years rather than forty.

Crypto & Blockchain

Transaction histories rebuilt across exchanges and wallets, and returns filed with the workings attached.

Entertainment

Royalties, income that arrives in lumps, and tax already withheld on work done abroad.

How we work

Records kept up to date in Xero, QuickBooks or Sage, so you always know where your money is going.

Bookkeeping and Payroll
