Business finance for window & door installers

The survey-to-install funding gap

Window and door installation — uPVC, aluminium and timber windows, composite and bi-fold doors, conservatories and glazing — runs on bespoke, made-to-measure product, and that is where the cash gets tight. A job follows a fixed sequence: survey and quote, customer order with a deposit, manufacture to size by the supplier, then fit. The frames can't be ordered until the survey is final, and the supplier usually wants a deposit, or payment on or before dispatch, before they cut glass and extrude or machine frames to your customer's exact opening.

The timing rarely lines up neatly. A homeowner typically pays a modest deposit on order and the balance on or shortly after completion, while you've already had to fund the supplier's deposit and often the full frame cost weeks earlier, plus the fitters' labour on install day. On commercial and new-build glazing the gap stretches further, with payment on the main contractor's terms or staged valuations. The made-to-measure nature means you can't carry stock to smooth it — every order funds its own frames up front.

Deposits, van stock and the everyday drag

Three pressures recur for installers:

• Supplier deposits on frames. The single biggest pinch — paying to have bespoke units made before the customer's balance lands.
• The deposit-to-balance gap. The customer's deposit rarely covers what you owe the supplier, so you fund the difference until completion.
• Van stock and consumables. Trims, cills, fixings, sealant, glass units for breakages and the everyday kit each fitter gets through.

Volume makes it sharper, not easier. Take on a busy run of installs or a small commercial contract and you have several sets of frames on order at once, each with a supplier deposit funded ahead of the homeowner's or contractor's balance. A strong order book is a heavier up-front funding requirement, not a lighter one — the more you sell, the more deposits you're carrying before the balances arrive.

What window and door installers use funding for

Working capital for installers typically covers:

• Supplier deposits on frames — funding bespoke windows and doors into manufacture before the customer's balance lands.
• The deposit-to-balance gap — bridging between the customer's deposit and the larger sum you owe the supplier.
• Van stock and consumables — trims, cills, glass units, fixings and sealant across the fitting team.
• Busy install runs — funding several orders' frames at once when work is flowing.
• Commercial and new-build glazing — carrying larger jobs paid on contract terms or staged valuations.
• Certification and competence — keeping FENSA or CERTASS registration and competent-person status current.

For vehicles and lifting or access equipment you'll keep for years, asset finance usually spreads the cost more cheaply. Short-term working capital suits the deposits, the stock and the wait to completion.

What to weigh up before you borrow

Tie the borrowing to confirmed orders. Funding supplier deposits against signed jobs with a deposit taken is sensible; treat the customer's deposit as money towards their job, not spare cash, and don't over-commit on supplier orders beyond what your confirmed pipeline supports. On commercial glazing, confirm the contractor's payment terms before you rely on them, since the gap can stretch well beyond a domestic balance.

Watch margin on fixed-price quotes — frame and glass prices can move between quote and order — and make sure it still absorbs the cost of finance. Look at the total repayable figure rather than a headline rate, and line repayments up against when balances and valuations actually clear. This is general information, not advice on your accounts — model it against your own order pattern and supplier terms.

How no-personal-guarantee company finance fits

Credicorp lends to the limited company, not to the director — so there is no personal guarantee and your personal assets are not pledged against a business facility. As an exempt business lender we provide short-term working capital to UK limited companies, structured around how an installation business actually orders, fits and gets paid.

For window and door installers that means money that lands when the supplier deposit is due and clears when the customer's balance or the contractor's valuation is paid. A business loan suits a single defined push — frames and labour on one large commercial glazing job. A revolving line such as Credicorp Flex fits the steady flow of domestic installs, letting you draw to fund deposits and repay as each balance lands, then draw again for the next order.
