Repair or replacement: compare the written options

Ask what each proposal actually resolves

A repair proposal should explain the task being offered and any uncertainty that remains. A replacement proposal should identify what is being replaced and what stays in place. Ask the professional to distinguish observed findings from assumptions about concealed components. If further investigation is needed, agree its scope and charging basis before treating the initial figure as a completed-job price.

A temporary measure is not necessarily the same scope as a permanent repair. Ask what follow-up is required and who will arrange it, without interpreting this website as advice about how long a temporary measure can remain. We provide no safe waiting period, equipment-life prediction or technical diagnosis. Those questions belong with an appropriately qualified professional who can assess the installation.

Compare complete costs rather than one component

Place labour, attendance, materials, disposal and making good in separate rows when comparing written options. Ask whether another visit is included, and whether opening or restoring surfaces is part of the proposal. A lower material price can be outweighed by different labour or access requirements. Conversely, a larger replacement scope may include work the repair option does not address.

Checkatrade’s UK guide, checked on 6 November 2026, lists emergency call-out fees of £100–£120 per attendance and emergency labour of £75–£150 per hour in its October 2026 rate table. Its VAT basis is not explicit. These are broad editorial figures, not estimates for either option at your property. Obtain each provider’s total including applicable VAT and identified exclusions.

• Are the two options addressing the same task?
• Are follow-up visits and making good included in each?
• Which costs are fixed and which remain estimates?

Discuss compatibility and future support

For a replacement, ask for the proposed product specification, compatibility assumptions and any associated changes needed. A similar-looking fitting may not have identical requirements. Ask who checks suitability and what happens if the product cannot be used when the installation is inspected. Do not buy parts on the assumption that this website has validated them.

For a repair, ask about the proposed part, availability and the written terms covering the completed work. For either option, establish who handles later questions and which guarantee or warranty terms apply. Different promises may cover the product and the installation separately. Retain the actual terms rather than relying on a headline claim, and ask about exclusions you do not understand.

Make an authorised and documented decision

If you are not the owner or the person funding the work, establish who must approve the choice. Rented and managed properties can have reporting and purchasing processes that differ from an owner-occupied home. Do not assume that selecting a replacement commits the landlord, insurer or managing agent to pay for it. Ask the relevant party directly and keep their response.

Once an option is agreed, retain the specification, scope, payment arrangement and process for approving changes. At completion, request an itemised invoice and written account of what was done and what remains. Our worksheet can help with stated arithmetic only; it cannot compare lifetime costs without reliable information, predict recurring failures or certify that either option is technically appropriate. Clear questions support a professional discussion, not a remote verdict.
