This guide explains typical card processing costs, how pricing works, and what builders merchants should look for when comparing providers.

Typical card machine costs for builders merchants in the UK

Most builders merchants process high-value transactions and a mix of debit and credit cards. Typical pricing in the UK often falls within these ranges:

• Debit cards: around 0.3% to 0.9%
• Credit cards: around 0.7% to 1.8%
• American Express: around 1.5% to 2.5%

However, these are only guide prices. The actual cost depends on how your pricing is structured and how different fees are applied across transactions.

Why headline rates can be misleading

Many providers advertise low headline rates, but builders merchants often find their effective rate is higher in practice. This is because additional fees may be applied depending on the type of card used, how the transaction is processed and the provider’s pricing model.

For example, a low advertised debit rate may not reflect:

• Premium or business card fees
• Interchange and scheme costs
• Terminal rental or service charges

This is why many businesses focus on their effective rate — the true average cost across all transactions.compare card machine providers

Terminal costs for builders merchants

Card machine costs are another part of the overall pricing structure. Builders merchants often use a mix of countertop and portable terminals.

• Rental: typically £15 to £30 per month per terminal
• Purchase: around £150 to £500 depending on the device

The right setup depends on how payments are taken — at the counter, in the yard, or across multiple locations.

Settlement speed and cashflow

One of the biggest differences between providers is how quickly funds reach your account.

Traditional providers often settle funds within 1 to 3 working days. Some modern payment platforms offer much faster settlement options, including same-day or near-instant funding.

For builders merchants processing high daily volumes, faster settlement can have a noticeable impact on cashflow and working capital.

How to compare card machine pricing for builders merchants

When comparing providers, builders merchants should look beyond headline rates and focus on the full pricing structure.

• Effective rate across all transactions
• Terminal costs and contract terms
• Settlement timing
• Reporting and visibility

A provider with a slightly higher headline rate may still offer better overall value if settlement is faster or pricing is more transparent.

How builders merchants reduce card processing costs

Many builders merchants reduce their costs by reviewing their current provider and comparing alternative options. compare card machine providers
