IT Support for Accountants and Accountancy Firms in London
Managed IT and cyber security for practices that hold clients’ financial records, bank details and tax logins. Protection against scam emails, secure file sharing with clients, safe working from home, and one dedicated engineer who knows your practice.
The IT risks accountancy practices face
Accountants hold everything a fraudster needs: bank details, National Insurance numbers, payroll records and logins to client and HMRC accounts. These are the problems we see most often in accountancy practices.
Scam emails and fake HMRC messages
Criminals send fake HMRC, client and supplier emails, especially in the run-up to tax deadlines when staff are busy and under pressure.
Client financial data
A lost laptop, a weak password or a document sent to the wrong person can expose client records and lead to a data breach you have to report.
Stolen logins
Access to accounting software, online banking and HMRC accounts is valuable. One stolen password can open the door to client money and records.
Downtime at deadline time
A broken computer, an email outage or a slow connection in January or at year end costs fees, overtime and client goodwill.

Every January we’d get a wave of fake HMRC emails, and one nearly caught a junior member of staff. Since Guard IQ took over, they’re blocked before they reach anyone and the team knows what to look out for.
Half our team works from home during busy season. Guard IQ set it up so everyone can get to our accounting software securely, and logins are properly protected.
As a small practice, we wanted one person who understands our setup and our deadlines. We always deal with the same engineer and everything is explained without jargon.

IT support for accountants: common questions
Can’t see your question? Call us on 020 8537 8167.
Do you provide IT support for accountants across London?
Yes. We support accountancy practices across North West London, Central London and Hertfordshire, with same-day onsite attendance in our core North West London area and remote support for every practice, including staff working from home.
Can you support our accounting and tax software?
Yes. Whether you use desktop software installed in the office or cloud accounting, we keep the computers it runs on secure and up to date, help your team day to day, and deal directly with the software provider when something goes wrong.
How do you protect an accountancy practice from HMRC scam emails?
We block scam and fake emails before they reach staff, switch on two-step login for every account so a stolen password is not enough to get in, and train your team to spot fake HMRC, client and payment requests, especially in the busy months before tax deadlines.
How can we share files securely with clients?
We set up secure file sharing through your Microsoft 365 account, so you can send and receive tax returns, accounts and ID documents with links that can expire and be limited to the right person, instead of unprotected email attachments.
Can staff work securely from home or another office?
Yes. We set up secure remote access so staff can reach practice software and client files from home or another location, with two-step login and every computer protected and monitored.
Do accountancy firms need Cyber Essentials?
It is not a general legal requirement, but clients, insurers and larger organisations increasingly ask for it. Under the 2026 rules, a firm fails automatically if two-step login is missing or important security updates are left for more than 14 days. Our plans take care of both.
What happens if our IT fails close to a tax deadline?
Critical problems get a response within 1 business hour. We also monitor your computers around the clock and schedule updates away from your busiest periods, so problems are spotted and fixed before deadline week.
How does switching from our current IT provider work?
We check your current notice period, take over the admin logins, set up monitoring and security, and move anything needed without disrupting client work. Most practices are fully onboarded within 30 days.
