Selling a Business in the South East: Hampshire, Berkshire, and Oxfordshire
If you're an owner-manager in the Thames Valley or Southern counties thinking about exit, you're operating in one of the UK's most active mid-market deal environments. Buyer appetite in this region — from London trade buyers, international acquirers, and sector-specific consolidators — is consistently strong. That said, the region is not homogeneous: a defence supply chain business near Portsmouth faces a completely different process from a professional services firm in Reading. Understanding what drives value and who the likely buyers are in your part of the South East will save you time and significantly improve your outcome.

What makes the Thames Valley and Southern counties different from the rest of the South East?
The Thames Valley corridor — stretching from Slough and Windsor through Reading, Wokingham, and out to Oxford — is one of the densest concentrations of technology and professional services businesses outside London. Decades of UK headquarters and EMEA operations from international companies (technology, pharma, financial services) have created a substantial ecosystem of owner-managed businesses that supply, support, and service those large organisations.
This matters for your sale because it shapes the buyer pool. A professional services or technology-enabled business in Reading or Maidenhead is highly visible to London-based private equity, trade buyers headquartered in the Thames Valley, and international acquirers already operating in the area.
Hampshire has a different character. The defence and aerospace cluster around Fareham, Portsmouth, and the wider Solent corridor — anchored by major players like BAE Systems and QinetiQ — has generated a large supply chain of owner-managed businesses. Southampton's maritime, logistics, and professional services base adds further depth. Winchester and the surrounding area are home to professional services and consultancy businesses with strong regional client relationships.
Oxfordshire brings a third distinct profile: research-intensive businesses connected to the university ecosystem, a growing pharmaceutical and life sciences presence, and a technology sector that has matured significantly over the past decade.
What sectors see the most M&A activity in Hampshire, Berkshire, and Oxfordshire?
Activity is concentrated in the following areas across this geography:
- Thames Valley: technology services, professional services, facilities management, business services, recruitment (particularly specialist technical and professional)
- Hampshire / Solent: defence supply chain (engineering, systems integration, specialist manufacturing), maritime services, construction and fit-out, healthcare services, professional services
- Oxfordshire: pharmaceutical services and CROs, specialist manufacturing, technology, professional services, construction
Defence and aerospace supply chain transactions require particular care around security clearance, sensitive contract disclosure, and ITAR/export control restrictions. These are not reasons to avoid a sale — but they do mean your process needs to be structured carefully from the outset.
What EBITDA multiples are realistic in this region?
Multiples vary by sector, scale, and quality of earnings rather than geography per se — but the buyer appetite in this region supports competitive outcomes. The table below gives indicative ranges for owner-managed businesses in the £2.5m–£25m revenue range.
| Sector | Indicative EBITDA Multiple Range | Notes |
|---|---|---|
| Technology services / IT managed services | 6x – 10x | Recurring revenue, customer concentration, and team depth are key drivers |
| Professional services (B2B) | 5x – 8x | Depends heavily on key-person risk and contracted revenue |
| Defence supply chain (engineering/manufacturing) | 4x – 7x | Contract visibility and security clearances add complexity |
| Facilities management / business services | 4x – 7x | Contract tenure and client mix matter significantly |
| Pharmaceutical services / CRO | 6x – 10x | Strong buyer appetite; sector commands premium |
| Specialist manufacturing | 4x – 7x | Niche positioning and IP improve multiples |
| Recruitment (specialist/technical) | 4x – 6x | Permanent vs. contract mix affects valuation approach |
| Healthcare services | 5x – 8x | Regulated businesses attract strategic buyers |
Multiples are EBITDA-based and represent indicative ranges for completed transactions at the time of publication. Individual outcomes will vary.
Who are the likely buyers for your business?
The buyer universe here is broader than in many UK regions.
London and international trade buyers are routine acquirers of Thames Valley professional services and technology businesses. The proximity to London (30–60 minutes by train) means London-based buyers treat this region as part of their natural acquisition territory.
International strategic buyers — particularly North American and European groups — are active in the Thames Valley specifically because they already have a footprint here. An acquisition in Reading or Oxford is often part of a broader EMEA growth strategy.
Private equity and buy-and-build platforms are active across professional services, facilities management, and healthcare. The region's density of quality owner-managed businesses makes it a productive hunting ground for roll-up strategies.
Defence and government services consolidators are the primary buyer type for Hampshire supply chain businesses. These are typically larger primes, specialist mid-market defence groups, or private equity platforms with a defence focus. Buyer qualification matters: not all interested parties will have the security clearances or sector knowledge to complete a transaction involving sensitive contracts.
Management buyouts remain viable, particularly where there is a strong second-tier management team and the business is at the lower end of the revenue range.
What does the adviser landscape look like here?
This region is well-served, which is an advantage. You broadly have three pools of adviser to draw from:
London advisers are accessible for businesses across the region and are often appropriate for Thames Valley businesses where the buyer pool is London-centric or international. Journey times from Reading, Oxford, or Southampton to London are short enough that working relationships are practical.
Thames Valley regional advisers — based in Reading, Oxford, and surrounding towns — have deep networks in the local business community and strong relationships with regional professional services firms. For businesses where local knowledge adds value to the process, these firms are worth considering seriously.
Hampshire and Solent advisers — based in Southampton, Portsmouth, and Winchester — tend to have strong relationships with the defence, maritime, and construction sectors. For supply chain and specialist manufacturing businesses, sector-specific knowledge at adviser level is genuinely valuable.
For all transactions, you will also need a specialist corporate solicitor experienced in SPAs and mid-market deal structures, and a tax adviser familiar with BADR and the implications of deal structuring on your personal tax position.
What are the key process steps for selling a business in this region?
The process is broadly the same across UK regions, but the timeline and buyer engagement stages are worth setting out clearly.
- Pre-sale preparation — typically 3–6 months before going to market. Clean up management accounts, resolve any outstanding legal or compliance issues, assess key-person dependency, and consider whether your structure (shareholding, property, pension) is optimised for sale.
- Appoint your adviser team — corporate finance adviser, solicitor, and tax adviser. These should be appointed before you approach any buyers.
- Prepare the information memorandum — a detailed, honest, and well-structured document presenting the business to prospective buyers. For defence businesses, this requires careful thought about what can be disclosed at each stage.
- Approach the market — your adviser will run a structured or targeted process, approaching likely buyers in a controlled sequence. Thames Valley and Oxfordshire businesses will typically attract both London and international interest; Hampshire defence businesses will require a more targeted, qualified approach.
- Receive and evaluate offers — initial offers (indicative only) are followed by Heads of Terms (HoTs) with a preferred bidder.
- Due diligence — typically 8–12 weeks. Expect detailed commercial, financial, legal, and (for regulated or defence businesses) compliance due diligence.
- SPA negotiation and completion — legal negotiation of the Share Purchase Agreement, warranty and indemnity insurance, and final completion. Typical deal timeline from appointment to completion: 6–12 months.
What tax considerations apply to your sale?
The principal reliefs available to owner-managers selling UK companies remain Business Asset Disposal Relief (BADR) and, in relevant structures, Employee Ownership Trust (EOT) relief.
Under current rules (April 2026), BADR applies at a 14% Capital Gains Tax rate on qualifying gains up to a £1m lifetime limit. The standard CGT rate for higher and additional rate taxpayers on share disposals sits at 24%. If your gain is likely to exceed £1m — which is common in this region given business values — the tax planning around structuring, consideration timing, and earn-out treatment is material and should be addressed early.
EOT sales remain exempt from CGT for qualifying disposals and can be a genuine exit route where the owner values employee continuity and the business has a suitable management team to carry it forward.

Frequently asked questions
How long does it typically take to sell a business in Hampshire, Berkshire, or Oxfordshire? From appointing your adviser team to completion, allow 6–12 months for a well-prepared business. Businesses requiring security clearance or ITAR compliance checks in due diligence can run longer. Starting preparation 12–18 months before your target exit date gives you the best control over timing.
Do defence supply chain businesses sell at lower multiples because of the complexity involved? Not necessarily. Contract visibility, repeat revenues, and niche technical capability in a defence supply chain business can command strong multiples — the complexity of the process is a different issue from the valuation. A well-run business with long-term MOD or prime contractor relationships is attractive to the right buyer.
Will London advisers understand my Hampshire or Oxfordshire business? Some will, some won't. Sector knowledge matters more than geography. A London adviser with a strong defence or pharmaceutical services track record will add more value to those deals than a regional generalist without it. Ask about recent completed transactions in your sector, not just their geography.
What is the buyer appetite for Thames Valley professional services businesses right now? Appetite from both private equity and trade buyers remains strong for professional services businesses with recurring revenues, a diversified client base, and a team that can operate independently of the founder. Key-person dependency is the most common reason buyers reduce their offer or walk away.
Can I use an EOT structure if my business has defence contracts? Yes, in principle. The EOT structure is a legal and tax matter, not directly connected to your contract portfolio. The practical question is whether your management team is capable of running the business independently post-sale and whether the EOT structure is financially viable given your valuation expectations.
What should I do first if I'm thinking about selling in the next two to three years? Get an independent valuation of your business so you have a realistic anchor for your planning. Then work backwards: address any structural issues (key-person risk, contract terms, accounting quality) that would reduce value or complicate due diligence. Two to three years is a comfortable runway to address most issues — one year is tight.
