Mira is a registered trade mark of subsidiaries
of Caradon Mira Limited.
The company reserves the right to alter product
specifications without notice.

Failing this, contact your installer to ensure that the product has
been installed and commissioned in full accord with our detailed
installation instructions. Our Customer Services is available, on
the number shown below, to advise you or your installer.

If this does not resolve the difficulty, contact our Customer
Services who will give every assistance and, if appropriate,
arrange for our local Service Engineer or Agent to call on a
mutually agreeable date.

If, through circumstances beyond our control, we are unable to
provide this cover we will, with prior agreement, authorise a
competent local installer to attend.

Within the Guarantee period there will be no charge for the parts
or labour insofar as a fault with our product is concerned.
However, it is important to appreciate that our Guarantee
extends to our product only and that it does not cover difficulties
arising from incorrect installation or misuse.

During a Service visit a responsible person – familiar with the
purpose of the visit – should be present. Should our Service
Engineer or Agent be unable to gain access at the pre-arranged
time a callout charge may be made.

Payment for Service visits, if applicable, should be made
directly to the Service Engineer or Agent, using either Visa,
Access or a cheque supported by a banker’s card.

Guarantee

Caradon Plumbing Solutions guarantee this product
against any defect of materials or workmanship for one
year (three years for the Mira Excel thermostatic range)
from the date of purchase, provided that the product has
been installed correctly and used and maintained in
accordance with the instructions supplied.

Any part found to be defective during the guarantee
period will be replaced or repaired – at our option – without
charge, provided that the product has been properly used
and maintained.

The product should not be taken apart, modified or
repaired except by a person authorised by Caradon
Plumbing Solutions.

Your statutory rights are in no way affected by this
guarantee.

After  Sales  Service  – how  we  can
help you

Caradon Plumbing Solutions have a team of expert staff
ready to provide assistance, should you experience any
difficulty with your Mira shower.

The Caradon Plumbing Solutions Customer Services is
available to give you advice on any problem encountered.
Should the problem be unable to be resolved by advice,
we will offer either a replacement part to be sent to you,
or for one of our Service Engineers or Agents to call.

Spare Parts

At Caradon Plumbing Solutions we keep a stock of all
functional parts of our products for up to ten years from
the date of final manufacture of the product.

If during that period, our stock of a particular part is
exhausted we will, as an alternative, provide an equivalent
new product or part at a price equating to the cost of
repair to the old, bearing in mind the age of the product.

Caradon Plumbing Solutions will normally despatch
spare parts within two working days and by 1st class
post. In the interests of customer safety, spares that
require exposure to areas of mains voltage can only be
sent to a competent person.

Payment for such parts – if applicable – can be made by
Visa or Access over the phone at the time of ordering.
Should payment by cheque be preferred a pro forma
invoice will be sent.

Customer Care Policy

If within a short time of installation the product does not
function correctly, first check with the Installation, Operation
and Maintenance Guide to see if the difficulty can be
overcome by simple home maintenance.
