In short

GP partnership buy-in finance pays for the capital a new partner puts into the practice: usually their share of the partnership's working capital and, where the partners own the surgery, a share of the property equity. Because NHS practice goodwill cannot be sold in England and Wales, the price is set by the capital accounts and the premises, not a goodwill valuation. Lenders focus on the partnership agreement, the practice's contract and list, and the incoming partner's share of profit.

This page is for salaried GPs, locums and GP registrars who have been offered a partnership, and for practices working out how a new partner will fund their entry. The sums involved vary widely, from a modest working capital contribution in a leasehold practice to a much larger amount where the partners own the building. Smart Funding Solutions is a broker, not a lender: we search our panel of 300+ lenders, including those used to lending to medical partners, and arrange facilities from around £10,000 to £500,000+, with larger facilities available in suitable cases. For the full range of practice borrowing, see our GP practice loans hub.

What a GP buy-in actually costs

Buying into a GP partnership is different from buying into a law firm or an accountancy practice, because there is no goodwill to pay for. The sale of the goodwill of an NHS medical practice is prohibited in England and Wales, so an incoming partner is not paying for the patient list. What they are paying for usually falls into two parts.

Working capital. Partnerships need cash to pay staff and suppliers before NHS and other income arrives. Each partner's share of that is held in a capital account, and the partnership agreement says how much a new partner must contribute, over what period, and how it is repaid when they leave.
Property equity, if the partners own the surgery. Where the building is owned by some or all of the partners, a new partner is often expected, or invited, to buy a share of the property from a retiring partner. The price is normally the share of the property's value less the matching share of any mortgage. This is usually the larger element.

Some practices let new partners build up their capital account gradually by retaining part of their profit share. Others expect the full contribution on day one. The BMA's practical guide to taking on new GP partners covers what practices should settle before a partner joins, and is useful reading from the other side of the table.

Costs, risks and the first tax bill

Partners in a traditional partnership share unlimited liability for the practice's debts, including staff costs and leases. Taking on borrowing to join is a personal commitment on top of that. Read the agreement carefully, take independent legal and accountancy advice, and understand what happens to your capital, and to the property share, if you leave early.

Moving from salaried work to partnership changes how you pay tax. You stop receiving pay under PAYE and become self-employed, which usually means a first self-assessment bill and payments on account landing close together. New partners often underestimate this. If it arrives at an awkward time, an income tax loan can spread it, but it is better to plan reserves from your first drawings.

Interest on a loan used to buy a share in a partnership or contribute capital to it can qualify for income tax relief, subject to conditions and the overall cap on certain reliefs. HMRC explains the rules in its helpsheet on interest eligible for relief on qualifying loans (HS340). Confirm how it applies to you with your accountant before relying on it.

Finally, the practice has to register the change with the CQC and the commissioner. Lenders may ask for evidence that the CQC application to add a partner is under way before releasing funds.

Underwriting

What lenders check before funding a new partner

The partnership agreement

Whether there is a current, signed agreement or the practice is a partnership at will, and what it says about capital, profit shares, retirement notice, expulsion and the property. A practice without an up-to-date agreement is harder to lend into, and the BMA explains why an up-to-date partnership agreement matters.

The contract and the list

Whether the practice holds a GMS, PMS or time-limited APMS contract, list size trends, and income from enhanced services and the network it belongs to.

Your profit share

Your starting share, any parity period before you reach full share, and what that leaves after your pension contributions and tax.

Partner stability

How many partners there are, their ages, and who is planning to retire. A shrinking partnership concentrates liability for leases, staff and property on fewer people, and lenders know it.

The premises position

Who owns or leases the building, any existing mortgage, and whether the rent reimbursement covers the property costs.

Your personal credit

Existing borrowing, including any residential mortgage, and your credit file.

Checklist

Documents to gather

The partnership offer letter or heads of agreement, including the capital figure and your profit share
The partnership agreement and the deed of adherence you will sign
The last two to three years of practice accounts, with the capital account balances
Your recent payslips or, if you have locumed, your tax returns and tax calculations
If property is included: the surgery valuation, the current mortgage statement and the rent reimbursement details
Photo ID and proof of address

Ways to fund the buy-in

A loan to the incoming partner

The most common route for the working capital element is a term loan to the new partner personally, used to make the capital contribution. Lenders size it on the partner's expected share of profits rather than their salaried income, which is why a signed offer and the practice accounts matter so much. These loans are usually unsecured; see our page on unsecured business loans for how that type of borrowing is assessed. Borrowing of £25,000 or less by sole traders and small partnerships can be regulated consumer credit, which brings additional protections.

Where the buy-in includes the building, the usual approach is for the incoming partner to join the property-owning partners on a new or refinanced commercial mortgage, so the retiring partner's equity is paid out through the refinance rather than by a personal loan. This keeps the property debt long-term and secured on the building, where it belongs. The lender will look at the surgery's value and at the NHS rent reimbursement the practice receives for it; our page on GP surgery premises finance explains that side in detail.

Partnership-level borrowing

Sometimes the practice itself borrows to repay a retiring partner's capital, and the new partner's contribution is built up over time from retained profit. This spreads the cost across all partners and can make recruitment easier, but it increases the debt every partner is jointly responsible for. It is closer to a buyout of an outgoing owner than a personal buy-in.

Comparison

Route	Suits	Watch for
Personal term loan	Working capital contributions; leasehold practices	Repayments come from your drawings; guarantees and personal liability
Joining the surgery mortgage	Buying property equity from a retiring partner	Joint liability for the whole mortgage, not just your share
Practice borrowing	Partnerships that want to phase contributions	Debt shared by every partner, including the new one
Retained profit, no borrowing	Practices with strong reserves and patient partners	Lower drawings in the early years

We approach lenders on our panel that lend to incoming medical partners and, where the surgery is involved, commercial property lenders.
We compare the offers with you, including term, security, guarantees and early repayment terms.
The lender carries out its checks and makes the final decision.

If you are comparing partnership offers across professions, our general guide to partner buy-in loans covers firms where goodwill is part of the price. It is free to enquire; any broker fee is disclosed separately before you proceed.

FAQs

Questions clients ask

Do I have to buy into the surgery building to become a partner?

Not always. Some partnerships separate property ownership from the partnership itself, so a new partner can join without owning the building, sometimes with an option to buy in later. Others make it a condition. It is worth asking early, because it changes both the amount you borrow and the type of lending involved.

Can I get buy-in finance before I have signed the partnership agreement?

A lender can often give an indication on the basis of a written offer and the practice accounts, but most will want the signed agreement or deed of adherence before funds are released. Starting early gives time to resolve any gaps in the agreement that would otherwise hold up the loan.

What happens to my capital if I leave the partnership?

The partnership agreement sets how and when your capital account is repaid, and whether your property share must be sold to the remaining partners. Repayment is often staged over a period after you leave, so any loan you took to fund it may need repaying before your capital comes back to you.

Is it better for the practice to borrow instead of the new partner?

It depends on the practice's debt, the other partners' appetite and the tax position. Practice-level borrowing spreads the cost but binds every partner to it. Where a retiring partner's property share is involved, refinancing the surgery through commercial property finance is often cleaner than personal loans.

Is GP partnership buy-in finance secured?

It depends on what you are buying. A contribution to the partnership's working capital is often funded with an unsecured loan, usually backed by your personal liability. Buying a share of a partner-owned surgery is normally funded with a mortgage secured on your share of the property, sometimes alongside the existing partners' borrowing. Our page on GP surgery premises finance explains how lenders treat surgery buildings.
