A boiler quote signed in your own home, rather than at a showroom or trade counter, is usually classed as an “off-premises” contract in UK consumer law — and that classification carries its own statutory cancellation right, on top of anything the installer’s own terms say.

When this cancellation right actually applies

The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 give consumers a cancellation right specifically for contracts made off-premises — meaning the trader and consumer are together somewhere other than the trader’s own business premises, such as a survey or sales visit carried out at your home. Since a large proportion of boiler quotes and sales are arranged exactly this way — an engineer or salesperson visiting to survey the property and agree a price on the spot — this off-premises classification applies to a genuinely large share of domestic boiler contracts.

This is a different, and separate, cancellation right from anything the Consumer Rights Act 2015 provides for faulty goods. It exists purely because of where the contract was agreed, not because of any problem with the boiler or the work itself.

How the 14-day cooling-off period actually works

For a service contract like a boiler installation, the 14-day cancellation period runs from the day after the contract is made. You do not need to give a reason for cancelling within this window — it is an unconditional right, not one that depends on you having found a fault or a cheaper alternative. To cancel, you (or your representative) simply need to inform the trader of your decision to withdraw, using the trader’s cancellation form if one was provided, or “any other clear statement.” What matters for timing purposes is when you send that communication, not when the trader receives or acknowledges it.

Exceptions that can genuinely apply

A small number of situations narrow or remove this right, and it’s worth checking which applies to your specific job:

• Contracts under £42 are excluded from the Regulations’ cancellation requirements entirely.
• Urgent repairs specifically requested by the consumer — for example, calling out an engineer because you have no heating or hot water at all — are treated differently, since these are contracts the consumer has actively asked to be carried out urgently.
• Where you have expressly asked the trader to begin work before the 14 days are up, and acknowledged that doing so may affect your cancellation rights, the position changes — if the work has been fully completed with your agreement, you may lose the right to cancel once it’s finished.

Outside of these specific carve-outs, the ordinary 14-day right applies to a standard, non-urgent boiler installation agreed at your home.

How to actually cancel, and what a trader must do afterwards

Put your cancellation in writing where possible — an email or a written letter, even if the Regulations don’t strictly require a particular format — so there is a clear, dated record of when notice was given. Once you’ve validly cancelled, the trader is required to reimburse you within 14 days of being notified, including any deposit or upfront payment already made. Failing to provide clear information about cancellation rights before the contract was made is itself a breach the Regulations treat seriously — described in guidance as a criminal offence in more serious cases — which underlines that this isn’t a minor technicality traders can simply ignore.

What happens to any deposit if you cancel

A validly exercised cancellation within the 14-day window entitles you to a full refund of any deposit paid, since the Regulations require the trader to reimburse all payments received in connection with the cancelled contract. This is a materially different position from simply changing your mind about a contract agreed at a trader’s own showroom or premises, where no equivalent statutory cooling-off right automatically applies in the same way.

FAQs

Does this right apply if I went to a showroom to agree the boiler installation?

Generally no — the off-premises cancellation right is specifically about contracts agreed somewhere other than the trader’s business premises. A contract signed at a showroom or trade counter is treated differently under the Regulations.

Can I still cancel if the installer has already ordered the boiler?

Usually yes, within the 14-day window, unless you specifically asked for work to begin early and acknowledged in writing that this could affect your cancellation right. Ordering materials alone doesn’t automatically remove your right to cancel the contract itself.

What if I need the boiler installed urgently and can’t wait 14 days?

Genuinely urgent repair requests, such as having no heating or hot water at all, are treated differently under the Regulations, since you are the one asking for urgent work — it’s worth discussing this specifically with your installer if timing is critical.
