If you are developing commercial property in Slough, the right facility is rarely the cheapest headline rate. It is the one that funds the build to completion, holds through letting and sale, and leaves day-one equity for your next site. We arrange commercial property development finance across Slough and the wider Berkshire market, from senior debt through to JV equity.

We underwrite a Slough scheme on its commercial fundamentals, with the local residential market as a gauge of exit liquidity for any residential element. That market is thinner but functional, around 797 residential sales in the past year at a £386,000 median, which helps test the values for the homes in a mixed-use or conversion scheme.

Development finance structures for Slough schemes

We arrange the whole capital structure for Slough commercial schemes. Senior development finance funds the bulk of the build, typically to 65 to 70 percent of cost and 60 to 65 percent of gross development value. Stretch senior and mezzanine finance lift leverage when the appraisal supports it, reducing the equity you commit. JV equity fills the remaining gap for developers scaling beyond their own balance sheet. For operational schemes that let up or trade after completion, such as student accommodation, care homes, hotels or self-storage, stabilisation finance carries the asset from practical completion through to stabilised income. Once the scheme is stabilised or sold, development exit finance refinances it onto cheaper money while units sell or let, releasing equity for the next site in Berkshire.

Commercial development we finance across Slough

Each commercial asset class is underwritten on different tests by different lenders, and we arrange finance for all of them in Slough and across Berkshire. That covers student accommodation and offices, warehouses and logistics, care homes and healthcare, retail, hotels and leisure, industrial and mixed-use schemes, and the higher-growth classes of self-storage, data centres and life sciences. Knowing which lender backs which sector here, and at what leverage, is the work we do before a scheme ever reaches a credit committee.

What the Slough market means for your appraisal

Slough is a mid-market location within Berkshire, where development margins depend on disciplined costs and a realistic exit. That profile suits senior development finance with a modest stretch or mezzanine top-up, and it is among the more straightforward backdrops for a lender to underwrite.

Residential market depth as exit context

Residential sold-price depth is one input a development lender uses to gauge exit liquidity, particularly for the residential element of mixed-use, build-to-rent and conversion schemes. Slough recorded around 797 residential sales over the past year at a median of £386,000, which makes the local market thinner but functional. New-build stock carries a premium of -27% over existing stock here. Commercial values turn on covenant, yield and sector demand, which we assess scheme by scheme.

This residential mix is exit context for the homes within a mixed-use or conversion scheme. It is not a guide to commercial values, which are sector and covenant driven.

FAQ

Commercial property development finance in Slough: common questions

How much commercial property development finance can I raise in Slough?

Most senior lenders fund up to 65 to 70 percent of total cost, capped at 60 to 65 percent of gross development value, with stretch senior or mezzanine lifting that toward 85 to 90 percent of cost on a strong scheme. The Slough exit market, currently thinner but functional, informs the gross development value a lender will accept.

Which lenders provide development finance in Slough?

We hold more than one hundred lender relationships across banks, challenger banks, debt funds and private capital. The right lender for a Slough scheme depends on the sector, the leverage you need and your track record, and we shortlist the desks most likely to back it across Berkshire.

How does the Slough residential market affect a commercial scheme?

It matters mainly as exit context for the residential element of mixed-use, build-to-rent and conversion schemes. HM Land Registry records a £386,000 residential median in Slough over the past year across roughly 797 sales, with flats around £215,000. Commercial values, by contrast, turn on covenant, yield and sector demand, which we assess scheme by scheme.

Do you fund commercial development beyond Slough?

Yes. We arrange commercial property development finance across the whole of Berkshire and the wider UK, with the same approach: model the capital stack, match the scheme to the lenders that back its sector, and negotiate terms on the developer's behalf.
