Outsourced Bookkeeping Services in the UK: Pricing, Benefits & How to Choose
A comprehensive guide to outsourced bookkeeping for UK businesses. Understand MTD compliance, HMRC requirements, typical pricing in GBP, and what to look for in a provider.
The UK market for outsourced bookkeeping services has grown significantly over the past decade, driven by increasing regulatory complexity, the rollout of Making Tax Digital (MTD), and a growing recognition among business owners that professional financial management is not a luxury but a necessity.
Whether you run a sole trader operation in Manchester, a limited company in London, or a growing SME in Edinburgh, managing your books in compliance with HMRC regulations, Companies House requirements, and UK GAAP standards demands time, expertise, and attention to detail. For many UK businesses, outsourcing this function is the most cost-effective and reliable way to stay compliant while focusing on growth.
According to recent industry reports, over 60% of UK SMEs now outsource at least part of their bookkeeping or accounting function. The trend has been accelerated by the shift to cloud-based accounting software, which makes it seamless for an external team to manage your books in real time regardless of where they are located.
In this guide, we cover everything a UK business needs to know about outsourced bookkeeping: from the regulatory landscape and compliance obligations, to pricing breakdowns in GBP, to how to evaluate and choose the right provider for your specific needs.
The UK Bookkeeping Landscape
The UK has one of the most well-regulated business environments in the world. HMRC (Her Majesty's Revenue and Customs) oversees tax compliance, while Companies House governs corporate filings. Understanding the regulatory framework is essential before choosing an outsourced bookkeeping provider.
HMRC Requirements
All UK businesses must maintain adequate financial records for tax purposes. HMRC requires that records are kept for at least six years and must be sufficiently detailed to support your tax returns. For VAT-registered businesses, this extends to maintaining digital records under Making Tax Digital regulations. Failure to maintain proper records can result in penalties ranging from £100 to £3,000, and in severe cases, HMRC may estimate your tax liability.
Making Tax Digital (MTD)
MTD is HMRC's flagship initiative to modernise the UK tax system. Since April 2022, all VAT-registered businesses must keep digital records and submit VAT returns using MTD-compatible software. From April 2026, MTD for Income Tax Self Assessment (MTD for ITSA) will be mandatory for self-employed individuals and landlords with qualifying income over £50,000, extending to those with income over £30,000 from April 2027.
MTD Timeline for UK Businesses
- April 2022: MTD for VAT mandatory for all VAT-registered businesses
- April 2026: MTD for ITSA mandatory for income over £50,000
- April 2027: MTD for ITSA extended to income over £30,000
- Future: MTD for Corporation Tax (date TBC by HMRC)
FRS 102 and FRS 105 Standards
UK businesses must prepare their financial statements in accordance with either FRS 102 (the Financial Reporting Standard applicable in the UK and Republic of Ireland) or FRS 105 (the micro-entities regime). FRS 102 is the primary standard for most UK companies, covering everything from revenue recognition to financial instruments. FRS 105 offers simplified reporting for micro-entities that meet size thresholds (turnover not exceeding £632,000, balance sheet total not exceeding £316,000, and no more than 10 employees).
An outsourced bookkeeping provider handling UK accounts must be thoroughly familiar with these standards to ensure your financial statements are prepared correctly and accepted by Companies House and HMRC without issue.
Key UK Accounting Bodies
Global body with strong UK presence; ACCA-qualified accountants are highly regarded.
Premier UK chartered accountancy body; the ACA qualification is considered gold standard.
Focused on management accounting; ideal for providers offering strategic finance support.
Foundational qualification; AAT-qualified bookkeepers handle day-to-day transaction processing.
Benefits of Outsourced Bookkeeping for UK Businesses
UK businesses face unique challenges including complex VAT rules, frequent regulatory changes, and the ongoing MTD rollout. Here is why outsourcing your bookkeeping function makes sense.
Significant Cost Savings in GBP
A full-time bookkeeper in the UK typically earns between £22,000 and £32,000 per year, plus employer National Insurance contributions (13.8%), pension auto-enrolment (minimum 3%), and other employment costs. When you factor in recruitment, training, sick pay, holiday pay, and office space, the total cost of employment easily reaches £35,000 to £50,000 annually.
Outsourced bookkeeping for a similar scope of work typically costs between £600 and £1,800 per month (£7,200 to £21,600 per year), delivering savings of 40-65% compared to an in-house hire.
Compliance Confidence
UK tax law changes frequently. In recent years alone, we have seen IR35 reform, changes to the VAT threshold, the introduction of plastic packaging tax, and the rollout of MTD. An outsourced provider with dedicated UK compliance expertise stays on top of these changes so you do not have to. They ensure your books are always ready for HMRC inspection, VAT submissions are timely, and Companies House filings are accurate.
Access to a Full Team of Experts
Instead of relying on a single in-house bookkeeper, outsourcing gives you access to an entire team with diverse expertise. Your provider typically has specialists in VAT, payroll, management reporting, and year-end accounts preparation. This breadth of knowledge is especially valuable for UK businesses dealing with complex VAT scenarios such as partial exemption, reverse charges, or cross-border services.
Scalability Without Recruitment Headaches
As your UK business grows, your bookkeeping needs evolve. You might start as a sole trader and incorporate as a limited company, or expand from one entity to several. An outsourced provider scales with you without the time and cost of hiring, training, and potentially making redundant additional staff.
MTD-Ready Technology
Professional outsourced providers already use MTD-compatible software such as Xero, QuickBooks, Sage, or FreeAgent. They manage your digital records, ensure digital links are maintained (no copy-paste from spreadsheets), and handle your quarterly VAT submissions directly through the HMRC API.

Typical Pricing for Outsourced Bookkeeping in the UK
Pricing varies based on business size, transaction volume, and the level of service required. Below are typical ranges you can expect in the UK market in 2026, expressed in GBP.
| Service Tier | Monthly Cost (GBP) |
|---|---|
| Basic Bookkeeping | £200 - £600 |
| Full-Service Bookkeeping | £600 - £1,800 |
| Bookkeeping + Controller | £1,800 - £4,500 |
| Full Finance Function | £4,500 - £12,000+ |
Tip: Factors That Affect Your UK Pricing
The single biggest factor is transaction volume. A retail business processing thousands of daily transactions will pay significantly more than a consultancy with 30 invoices per month. Other major factors include whether you are VAT-registered (VAT return preparation adds cost), the number of bank accounts and credit cards, payroll complexity, and whether you need CIS (Construction Industry Scheme) returns.

- - Onboarding/setup: £300 - £2,000
- - Historical cleanup: £40 - £100/hour
- - Year-end accounts prep: £500 - £3,000

UK-Specific Compliance Requirements
Your outsourced bookkeeping provider must handle or support all of the following UK compliance obligations. Make sure any provider you evaluate can demonstrate competence in each area.
VAT Returns
If your business is VAT-registered (mandatory if taxable turnover exceeds £90,000), you must file quarterly VAT returns via MTD-compatible software. Your bookkeeper must accurately categorise transactions by VAT rate (standard 20%, reduced 5%, zero-rated, exempt), handle reverse charges for services received from abroad, manage partial exemption calculations if you make both taxable and exempt supplies, and submit returns through the HMRC API.
Key deadline: VAT returns and payment are due one month and seven days after the end of each VAT quarter. Late filing incurs automatic penalties under HMRC's points-based penalty system.
PAYE and Payroll
If you employ staff, you must operate PAYE (Pay As You Earn) and make Real Time Information (RTI) submissions to HMRC before or on each payday. This includes calculating Income Tax and employee/employer National Insurance contributions, administering statutory payments (SSP, SMP, SPP), managing student loan deductions, and submitting Full Payment Submissions (FPS) and Employer Payment Summaries (EPS). Your outsourced provider should either handle payroll directly or integrate seamlessly with your payroll provider.
Corporation Tax
UK limited companies must file a Company Tax Return (CT600) within 12 months of the end of the accounting period, with Corporation Tax payment due nine months and one day after the period end. The current Corporation Tax rate is 25% for profits over £250,000, with a small profits rate of 19% for profits under £50,000 and marginal relief in between. Your bookkeeper should maintain records that make year-end accounts and CT600 preparation straightforward for your accountant or tax adviser.
Companies House Filings
All UK limited companies must file annual accounts with Companies House and submit a Confirmation Statement at least once every 12 months. Small companies may file abbreviated or micro-entity accounts. Your bookkeeping provider should prepare accounts in the correct iXBRL format (inline XBRL) required for electronic filing, or at minimum produce trial balances and supporting schedules that allow your accountant to prepare the statutory accounts efficiently.
CIS (Construction Industry Scheme)
If you operate in the construction industry, either as a contractor or subcontractor, you must comply with CIS requirements. Contractors must verify subcontractors with HMRC, make deductions from payments (20% for registered, 30% for unregistered subcontractors), and submit monthly CIS returns. This is a specialised area that not all bookkeeping providers handle, so confirm this capability if relevant to your business.
Key UK Compliance Deadlines
Choosing a Provider for UK Operations
Not every outsourced bookkeeping provider understands the nuances of UK taxation and reporting. Here is what to evaluate when choosing a provider for your UK business.
ACCA/ICAEW/AAT Qualifications
Ensure the team working on your books holds recognised UK qualifications. ACCA and ICAEW indicate chartered-level expertise; AAT is suitable for day-to-day bookkeeping. Ask to see qualification certificates and check professional body registers.
UK GAAP Knowledge
Your provider must understand FRS 102 and FRS 105 accounting standards, including recent amendments. They should know the differences between UK GAAP and IFRS, especially if your business is part of a group that reports under international standards.
HMRC Experience
Look for providers with direct experience interacting with HMRC. They should be familiar with the Government Gateway, the HMRC agent services account, MTD API submissions, and handling HMRC correspondence or enquiries on your behalf.
MTD-Compatible Software
Confirm the provider uses HMRC-recognised MTD-compatible software. Popular choices include Xero, QuickBooks Online, Sage Business Cloud, and FreeAgent. The software must maintain digital links and support direct API submissions.
Data Security and GDPR
Under UK GDPR and the Data Protection Act 2018, your provider is a data processor handling sensitive financial information. They must have appropriate technical and organisational measures, clear data processing agreements, and ideally hold certifications like ISO 27001 or Cyber Essentials.
Professional Indemnity Insurance
Any reputable UK bookkeeping provider should carry professional indemnity (PI) insurance. This protects you if errors in their work cause financial loss. Ask to see their certificate and check the level of cover is appropriate for your business size.
Red Flags When Evaluating UK Providers
- No UK-qualified staff on the engagement team
- Unable to name specific MTD-compatible software they use
- No professional indemnity insurance or unwilling to share details
- No clear data processing agreement or GDPR compliance documentation
- Cannot explain the difference between FRS 102 and FRS 105
- No experience with VAT partial exemption or reverse charges
- Quotes that seem unrealistically low with no scope definition
- No references from UK-based clients

Making Tax Digital: What It Means for Your Bookkeeping
Making Tax Digital is the single most significant change to UK tax administration in a generation. It fundamentally changes how businesses maintain records and interact with HMRC. Understanding MTD is essential when choosing an outsourced bookkeeping provider.
Digital Records Requirement
Under MTD, businesses must keep their records digitally using HMRC-recognised software. This does not simply mean typing figures into a spreadsheet. The software must be capable of receiving information from HMRC, maintaining digital links between different software programs used in the record-keeping process, and submitting returns directly to HMRC via API. Manual transcription of data (copy and paste between systems) is not permitted.
What "Digital Links" Means in Practice
Quarterly Updates Under MTD for ITSA
When MTD for Income Tax Self Assessment launches in April 2026, affected individuals will need to submit quarterly updates to HMRC summarising their business income and expenses. These are not full tax returns but rather periodic summaries that give HMRC (and the taxpayer) a running picture of the tax position. At the end of the year, a final declaration replaces the traditional Self Assessment tax return.
This means that if you are self-employed or a landlord with qualifying income, your bookkeeping must be up to date quarterly rather than being left to year-end. An outsourced provider ensures this happens consistently, removing the risk of missed quarterly deadlines and the penalties that follow.

Pro Tip
When choosing an outsourced bookkeeping provider for your UK business, ask which MTD-compatible software they recommend and whether software costs are included in their fee. Many providers include the software subscription as part of their package, which can save you £150-£400 per year. Also confirm they can handle the transition to MTD for Income Tax if it applies to you.
Offshore vs UK-Based Providers
One of the biggest decisions UK businesses face is whether to use a UK-based provider, an offshore provider, or a hybrid model. Each approach has distinct advantages and trade-offs.
| Factor | UK-Based Provider | Offshore Provider |
|---|---|---|
| Cost | Higher (£800-£2,500/mo for full service) | Lower (£300-£1,200/mo for full service) |
| UK Tax Knowledge | Deep, native understanding of HMRC and UK GAAP | Varies widely; best offshore providers train staff specifically on UK rules |
| Time Zone | Same time zone (GMT/BST), real-time collaboration | May have overlap; some providers offer UK hours coverage |
| Communication | Native English, familiar with UK business culture | Professional English; cultural nuances may require adjustment |
| Data Protection | Subject to UK GDPR; data stays within UK jurisdiction | Requires adequate safeguards for international data transfers |
| Scalability | Limited by local talent pool | Larger talent pools allow rapid scaling |
| Qualifications | ACCA, ICAEW, AAT qualified | Often ACCA qualified (global body); may also hold local qualifications |
Data Protection Considerations (GDPR)
Under UK GDPR, transferring personal data outside the UK requires adequate safeguards. If you use an offshore bookkeeping provider, you must ensure that appropriate transfer mechanisms are in place. These include adequacy decisions (the UK has recognised certain countries as providing adequate data protection), Standard Contractual Clauses (SCCs), or Binding Corporate Rules. Your provider should be able to demonstrate their compliance with these requirements and have a clear data processing agreement in place.
GDPR Checklist for Offshore Providers
- Written data processing agreement (Article 28 UK GDPR)
- Appropriate transfer mechanism (adequacy decision, SCCs, or BCRs)
- Clear data retention and deletion policies
- Technical security measures (encryption, access controls, audit logs)
- Incident response and breach notification procedures
- Staff training on data protection and confidentiality
- Regular security audits or certifications (ISO 27001, SOC 2)
The Hybrid Model: Best of Both Worlds
Many UK businesses are finding that a hybrid model offers the optimal balance. In this approach, a UK-qualified manager oversees the engagement and handles HMRC communications and complex advisory work, while an offshore team handles the day-to-day transaction processing, reconciliations, and routine reporting. This delivers the cost savings of offshore delivery with the compliance confidence of UK-based oversight.
The MZBPO Approach
MZBPO operates this hybrid model. Our team includes ACCA-qualified professionals who understand UK tax law and HMRC requirements. Day-to-day bookkeeping is handled by our trained team using cloud-based, MTD-compatible software, with UK-qualified oversight on every engagement. This gives our UK clients cost savings of up to 60% without compromising on compliance quality. As a BKR International member firm, we adhere to global quality standards that go beyond minimum requirements.
Conclusion
The UK bookkeeping landscape is becoming increasingly complex. With MTD expanding, Corporation Tax rates rising, and HMRC adopting a more technology-driven approach to compliance, having professional bookkeeping support is no longer optional for most businesses. Outsourcing offers a compelling combination of cost savings, expertise, and compliance confidence that is difficult to replicate with an in-house hire at the same price point.
Whether you choose a UK-based provider, an offshore partner, or a hybrid model, the key is to ensure your provider truly understands UK regulations, uses MTD-compatible technology, and has the qualifications and experience to handle your specific compliance obligations.
Key Takeaways
- UK outsourced bookkeeping typically costs £200-£1,800/month for SMEs, saving 40-65% compared to in-house hires
- MTD compliance is mandatory for all VAT-registered businesses and expanding to Income Tax from April 2026
- Look for ACCA/ICAEW/AAT qualifications and direct experience with HMRC, UK GAAP (FRS 102/105), and MTD-compatible software
- VAT, PAYE, Corporation Tax, and Companies House filings all have strict deadlines with automatic penalties for late submission
- Offshore providers can save 30-50% more but must demonstrate UK GDPR compliance and adequate UK tax knowledge
- A hybrid model with UK-qualified oversight and offshore delivery often provides the best balance of cost and quality
- Always check for PI insurance, data processing agreements, and references from UK clients before committing
