How to Open a Builders' Merchant Trade Account

A trade account at a builders’ merchant gives you two main things: access to negotiated prices below the standard cash rate, and a credit facility so you do not have to pay for every order at the point of collection. For sole traders, subcontractors and small building firms, a trade account at one or two local branches is often the single most effective way to reduce material costs and manage cash flow. This guide explains exactly how to open one, what you need and what to expect.

What a Trade Account Actually Gives You

The label “trade account” covers two distinct arrangements, and it is important to understand the difference before you apply.

Cash trade account (also called a cash customer or cash account): You have a registered account with the branch, which means the counter staff know you and your pricing is agreed in advance. But you pay at the point of purchase, there is no credit. This is the easiest account to open, often requiring nothing more than filling in a form with your name, business name and contact details. Cash trade accounts typically offer better prices than a walk-in customer gets, but not as good as a full credit account.

Credit account (monthly terms): This is the standard trade account. You buy throughout the month and receive a single monthly statement. At Travis Perkins, for example, payment is due at the end of the month following the date of invoice, which is what merchants usually mean by 30-day terms.¹ Longer terms are sometimes negotiated by high-volume customers, but end-of-month terms like these are the norm. Credit accounts require a formal credit check and trade references, and come with a credit limit set by the merchant, which can rise as you build a payment history.

Who Can Open a Trade Account

Merchants will open credit accounts for:

• Sole traders, you do not need a limited company. Provide your UTR (the 10-digit Unique Taxpayer Reference HMRC issues when you register for Self Assessment), proof of address and ideally a reference from a material supplier or subcontractor you have dealt with before.¹²
• Partnerships, as for sole traders; the merchant will want to know who the partners are.
• Limited companies, usually the most straightforward, as the merchant can check the company’s Companies House record and run a business credit report on it. Provide your company registration number, registered address and two trade references.
• Self-employed contractors, treated the same as sole traders in practice.

Homeowners renovating their own property often cannot open a full credit account, as there is no trading business to run a credit check against. Some merchants do take self-builders, though: Travis Perkins’ credit application lists Self Build alongside sole trader, partnership and limited company.¹ However, some merchants offer a “homeowner cash account” that locks in a price level and gives you a customer number. If you are running a significant project, it is worth asking your branch what they can do.

What You Need to Apply

Most merchants ask for the following on their application form:

• Business name and trading address
• Legal structure (sole trader, Ltd, partnership)¹
• VAT number (if registered; registration is compulsory once taxable turnover goes over £90,000 in a 12-month period)³
• Company registration number (if Ltd)¹
• UTR number (sole traders)
• Names and contact details of two trade references, ideally other merchants or suppliers you have accounts with⁴
• Bank details (bank name, sort code and account number)¹
• Principal director or owner’s name and date of birth (for credit check consent)¹

Some national chains run the application online; most smaller merchants and independents still use paper forms at the counter.

The Credit Check

For a credit account, the merchant will run a search with a credit reference agency.¹ It may also search the personal credit file of the owner or principal directors.¹ Directors of a limited company may be asked to sign a personal credit guarantee, which makes them answerable for the account if the company does not pay.¹ A poor credit history will not automatically disqualify you, but may result in a lower initial credit limit or a requirement to pay by direct debit. If your application is declined, ask what the specific issue is, sometimes it is as simple as a director’s address not matching records, which can be corrected quickly.

How Long Does It Take?

Some larger chains with online applications can be faster, occasionally same-day for limited companies with clean credit. If you need materials urgently, ask whether you can buy on cash terms while the account is being processed.

Pros and Cons of a Trade Credit Account

Advantages:

• Negotiated prices below standard cash/retail rates on core lines, with the discount set by your spend and the product category
• Monthly invoice simplifies bookkeeping, one payment covers multiple purchases
• Builds a relationship with branch staff, leading to better service and willingness to hold stock
• Credit limit provides working capital flexibility, particularly on projects where the client pays in arrears

Disadvantages:

• Requires active credit management, you must pay on time to maintain good pricing and credit limit
• Credit limit may be insufficient for large projects, requiring upfront cash on large orders until the limit is raised
• Opening accounts at multiple merchants takes time and attention
• If you pay late, the merchant may reduce your credit limit or require cash only
• Late payment can also cost money: unless the contract sets its own rate, a supplier can charge statutory interest of 8% plus the Bank of England base rate on overdue business debts⁵

Plumbing Merchants: Opening a Trade Account

Plumbers’ merchants work identically to general builders’ merchants, with a few quirks worth knowing. The large chains, Wolseley, City Plumbing, Williams and commercial specialist BSS, generally offer the same two-tier structure: a cash account opened quickly, and a monthly credit account on proof of business plus references. Gas Safe registration or plumbing qualifications are not normally needed to open an account, but presenting them can help, since merchants often set discounts by trade and by product category.

Two practical tips: first, negotiate your discount structure per category, not overall: the list-price margin on brassware and plastic is very different from copper tube, and a single blanket percentage always favours the merchant. Second, if you’re a general builder who buys occasional plumbing materials, ask whether your builders’ merchant account can be used at a plumbing business in the same group before opening a separate one. Group structures change, though: City Plumbing, for example, left Travis Perkins in 2021, when the group sold its Plumbing and Heating division to H.I.G. Capital.⁶

Can a Homeowner Get Trade Prices?

Trade accounts with credit facilities are mainly for businesses. However, several approaches can get a homeowner closer to trade pricing:

• Ask for a homeowner cash account. Some branches will register you as a named customer and apply a modest discount, particularly on a large project.
• Buy through your contractor. If you have a builder or tradesperson on site, they may be willing to purchase materials on your behalf through their account, passing on the trade price (you pay them directly). Confirm this arrangement in writing and ask for a copy of the merchant’s invoice for your records.
• Open a business account legitimately. If you run any freelance or self-employed work, even part time, you have a trading identity that can support a cash trade account at many merchants.

Getting Your Credit Limit Raised

A new account’s initial credit limit may not go far on a large project. To get it raised:

1. Use the account consistently and pay every statement on time for at least two to three months.
2. Ask your branch account manager for a limit review, most merchants will increase limits for reliable payers.
3. If you have a large project coming up, notify the branch in advance so they can factor in expected spend.

Some merchants assign you a dedicated account manager once you are spending above a certain monthly threshold, which varies by merchant. That relationship is valuable, they can expedite orders, hold stock and occasionally offer additional discounts at end of quarter.

Payment Methods

Most credit accounts are settled by bank transfer or direct debit. Some smaller merchants still accept cheques. Paying promptly, or early, occasionally earns goodwill, but few UK merchants offer formal early-payment discounts in the way that some European suppliers do.

Keep your account in good standing. A single missed payment rarely causes problems if you call and explain, but habitual late payment will result in your account being put on hold, which is highly disruptive mid-project.
