Common questions

Before you call

Will you take the old boiler or bathroom away?

Yes, removal and disposal are part of the job.

Do I need an EICR as a homeowner?

Only if you rent the property out. Landlords in England must have a valid EICR every five years and give a copy to tenants. Homeowners tend to get one before selling, after buying an older house, or when the consumer unit looks original to the building.

Who do I call if something fails at the weekend?

The out-of-hours number, 07879 234479. The office line, 01726 821 559, is answered Monday to Friday, 8am to 5pm.

What areas do you cover?

Cornwall and Devon, from St Austell and Truro across to Launceston and Saltash, and over the Tamar for Plymouth and Exeter. The full list of towns is on our contact page. If you are not sure whether you are in range, call the office and ask.

Do you give free quotes?

Yes, and there is no obligation attached. For anything beyond a small repair we come and look at the job first, because pricing plumbing or electrical work over the phone is guesswork.

Why use one firm for the plumbing and the electrics?

Because most jobs need both. A bathroom, a kitchen, an unvented cylinder, underfloor heating, a heat pump, an EV charger: every one of those is plumbing and electrics together. We hold both registrations, so one order covers the whole job.
