Who is this for?

  • High net worth borrowers with complex income, wealth held in assets rather than salary, or a loan of £1 million or more.
  • International buyers, expats and foreign nationals buying or refinancing UK property, including those paid in another currency.
  • Borrowers whose property is held through a company, a trust or an offshore structure.
  • Buy-to-let investors with large portfolios.

Before you call, understand your income flows over the last three years from all sources. Be ready to give an accurate summary of income and documentation.

This page is not for a salaried borrower with a standard property and deposit, whom a high street lender will usually serve better. If your case is simply large, see large mortgages.

Mortgages we arrange

  • London & UK Mortgages

    The UK, and particularly London, remains one of the world’s leading markets for prime and super-prime property. Through our Mayfair office, Enness Global assists domestic and international clients seeking tailored mortgage solutions for primary residences, second homes and investment properties across the UK.

  • Million Pound Mortgages

    Enness Global specialises in arranging large and complex mortgage facilities for high-net-worth borrowers. We assist clients seeking bespoke financing for prime residential property, investment acquisitions and refinancing requirements, including cases involving complex income, global assets and high-value lending structures.

  • Complex Mortgages

    Complex borrowing situations often require a more tailored approach than traditional high-street lending can provide.

  • International Mortgages

    Enness Global assists internationally mobile and foreign national clients seeking mortgage finance across multiple jurisdictions.

  • Large Buy-to-Let Mortgages

    Securing a large buy-to-let mortgage can become increasingly complex where borrowers have sizeable portfolios, complex income or specialist property requirements. Enness Global assists investors seeking tailored financing solutions for high-value residential investment properties across the UK and internationally.

Specialist mortgage guide

What is a specialist mortgage broker, and how is it different from a specialist lender?

A specialist mortgage broker is an FCA-regulated intermediary that assesses a borrower's case, chooses the lender route and prepares the application to that lender's standard. A specialist lender is the institution that makes the lending decision and provides the money.

A broker compares criteria across lender types and takes the case to the one whose appetite fits.

01

When you need a specialist broker

When does a borrower need a specialist mortgage broker rather than a high street lender?

A borrower needs a specialist mortgage broker when the case does not fit an automated affordability model. The usual reasons: income paid as bonus, dividends, carried interest or partnership profit; wealth held in investments; a loan of £1 million or more; property held in a trust; or income outside the UK.

High street models struggle when income is irregular or the loan is large; declines on criteria are common even for wealthy borrowers. A private bank may lend on the wider balance sheet, sometimes on condition that assets move to the bank. A specialist broker sets out both routes first.

Which mortgages does Enness Global arrange?

Enness Global arranges residential, buy-to-let, private bank and international mortgages for high net worth borrowers, and each route has its own page. By size: large mortgages and, above £10 million, high value mortgages. By income: complex mortgages. By lender: private bank mortgages. By residency: UK mortgages for international borrowers and foreign currency mortgages. For investors: buy-to-let mortgages. For capital raising: remortgages. For property abroad: international mortgages.

02

Complex income, residency and declines

How does a specialist mortgage broker present complex income to a lender?

A specialist mortgage broker presents complex income as a documented pattern rather than a single figure: what the borrower earned over two or three years, in what form and how reliably. That means accounts, tax computations, bonus and dividend history and trust statements.

Lenders differ in what they count. Some count all of a two-year bonus record; others count part. Some assess retained profit; many exclude it. The broker knows those positions before submission and packages the evidence in the order that lender's underwriter expects.

Can a specialist mortgage broker arrange a UK mortgage for a non-resident, or for income paid in a foreign currency?

Yes. A specialist mortgage broker can arrange a UK mortgage for a non-resident foreign national, a British expat or a borrower paid in another currency. A number of private banks, international banks and specialist lenders state in their criteria that they consider these borrowers, each with its own residency and currency rules.

Lenders usually apply a haircut to foreign currency income before affordability is assessed. Source-of-funds and identity checks on overseas wealth take longer than UK borrowers expect, so the adviser lists the documents at the first conversation. Changes in the exchange rate may increase the sterling equivalent of your debt.

Can a specialist broker help if a private bank or high street lender has already declined?

Yes, where the decline was on criteria rather than on credit. Most declines for wealthy borrowers happen because the case did not fit the lender's model. A specialist mortgage broker asks for the decline reason first, because it rules out a route.

A decline elsewhere is not an approval at Enness Global. In Islay Robinson's words: "One bank saying no is usually a particular criteria or policy point, and those criteria and policies are different lender to lender. Being refused by one lender is not an indication that you are uncreditworthy or that you will be unable to get a mortgage."

Applying

What will you need, and what does Enness do?

What Enness doesWhat you will need
Forms a view on the case, the route and your date, and agrees the fee in writingThe property or refinancing, the price or value, and your date
Chooses the lender type and issues the evidence listUnderstand your income flows over the last three years from all sources, and be able to give an accurate summary of that income with the documentation behind it
Packages the case to the lender's own standard before submissionProof of identity and address for each borrower, and the source of the deposit
Answers the lender's questions and reads the valuation with youExisting borrowing, other properties and outgoings
Records the offer conditions and expiry, briefs your solicitor and holds the timeline to completionYour solicitor's details early, and word of any change to income or assets

How does it get done, and how long does it take?

A specialist mortgage is run in six stages by a named adviser. First conversation: the adviser forms a view on whether the case is doable, which route fits and whether your date is realistic; the fee is agreed in writing. Plan and route: the lender type is chosen and the evidence list issued. Submission: the case is packaged to the lender's own standard and sent; a weak submission is the largest single cause of delay.

Valuation and underwriting: the lender's questions are answered and the valuation read. Offer: conditions and expiry recorded, your solicitor briefed. Completion: funds released, or the reason for a moved date recorded. Your adviser chases the lender, valuer and solicitor, not you.

Who lends on this

Who lends on this?

Of the 116 lenders whose residential criteria Enness Global tracks from published sources, 41 (around a third) state that they will consider complex income (Enness Lender Database, September 2026). Enness Global also places cases with lenders whose appetite it has confirmed directly. Terms depend on status, valuation and lender criteria.

What does Enness Global's CEO and Founder say about specialist mortgage broking?

"Each lender has a different risk profile and policy, reads certain pieces of information in different ways, and that gives different outcomes. Each application has to be tailored to specifically how that lender wants to write mortgage business."

Islay Robinson, CEO and Founder, Enness Global.

See his leadership page and islayrobinson.co.uk.

What is Enness Global's CEO and Founder seeing in specialist mortgages in September 2026?

There is ever increasing creativity in the specialist lending market. Given the number of lenders competing for business, we are often seeing banks find new ways to offer mortgages: rolled-up interest, monetising a particular asset, a higher loan to income ratio, a different assessment of expenses. We are also seeing signs of easing in mortgage regulation around loan to value and loan to income. There is a real dynamism in specialist mortgages in the UK. The mistake I still see, including from other brokers, is presenting the same case the same way to multiple lenders, as of September 2026.

Case snapshot and risks

An example: a £4.5 million interest-only mortgage at approximately 90 per cent loan-to-value

Completed case. Client type: a UK-based high net worth borrower. Situation: high borrowing on a prime residential purchase, preserving capital for investment. Property: valued at several million pounds. Facility: circa £4.5 million at approximately 90 per cent loan-to-value. Structure: interest-only, split across multiple lending tranches, repayment strategy agreed with the lender from the outset. Lender type: private bank. Dates: not held on the published record.

What could have gone differently: a low valuation would have re-sized the loan. Published in full at £4.5M mortgage at 90% LTV for a prime residential property purchase.

What are the risks and what could go differently?

Your date may not be achievable on the chosen route. Enness Global says so at the first conversation, offers the routes that can meet it or a bridge that buys time, and records the date.

The lender may ask for more evidence or a different presentation of income. Enness Global submits to the lender's standard first time and answers each question with your evidence. You provide the evidence list before submission.

A lender may decline despite substantial income and assets, usually on criteria. Enness Global explains why, records the reason and takes the case to the next route; a decline elsewhere is not an approval here. You decide whether to go on.

Lenders decline on criteria and change terms on valuation; a private bank offer may require moving assets, the trade-off of that route.

Who is accountable for your case?

A named adviser at Enness Global runs your case from the first conversation to completion and is your single point of contact. On this page that adviser is Islay Robinson, CEO and Founder, Enness Global (Islay Robinson). Your adviser plans the route with you, prepares the submission to the lender's standard, answers the lender's questions, and holds the timeline across the lender, the valuer and your solicitor. You do not chase any of them.

You will hear from your adviser at each stage named above, and immediately if a date moves or a lender asks for something that changes the plan. If you are not hearing from us, tell us: call +44 (0)203 758 9393 or email info@enness.co.uk.

If something goes wrong, tell your adviser first. If you are not satisfied with the response, you can raise a complaint with Enness Global under our complaints procedure.

Enness Global is a broker, not a lender. Your home may be repossessed if you do not keep up repayments on your mortgage.

Let's talk now

How much mortgage can I get?

The amount you can borrow depends on your full financial profile: income in all its forms, assets and liquidity, loan-to-value, property type, residency and each lender’s criteria. For high net worth borrowers, private banks and specialist lenders may consider dividends, bonuses, investment income and trust distributions alongside salary. All lending is subject to status, valuation and lender criteria.

This mortgage would not have happened without Enness. Enness is infinitely more informed than most brokers, and they both went the extra mile. I thoroughly recommend them and will undoubtedly be using their services again in the future. Thank you!

New Property Purchase

Enness was an unbelievable support for our family. They went above and beyond to help us through the process. From start to finish, Enness supported us and we would recommend them to anyone looking to purchase a new property, remortgage or otherwise.

UK - Warren A, Aug 14

Enness was fantastic!!...

Enness were fantastic and got the job done when no other broker could. Our circumstance was very unique, and through their connections, we were able to get a mortgage at a competitive rate.
Being that we're from America and not familiar with purchasing property in the UK, Enness answered all of our many questions and walked us through the process as if we were their only client.
