Spot on
Registered the new boiler for the warranty for me and emailed the certificate. Everything was explained properly without any jargon. Parking was easy too.

Popped in on the off chance on Thursday. Registered the new boiler for the warranty for me and emailed the certificate. They rang the next day to check everything was ok. Very happy.

Not impressed

Fine, would give 5 stars if the blocked drain had been ready when they said. The person I dealt with was polite at least.

Hi Fatima, thanks for the honest feedback. Sorry it took longer than it should have. Glad it got sorted in the end and thanks for bearing with us.

Proper service
Was dreading sorting the new shower. Even the kids were made welcome. Cheaper than the two other quotes we got and better reviewed. No hesitation in recommending.

Needed a radiator swap sorting quickly. Turned up when they said they would. Put dust sheets down everywhere without being asked.

Fine
Fixed the bathroom refit but the bill was more than the quote. Should have explained why before doing the extra. Price was fair which is why I didnt make more of a fuss.

Put dust sheets down everywhere without being asked. Turned up when they said they would, which is rare these days. Registered the new boiler for the warranty for me and emailed the certificate. Been telling everyone about them. Sorted.

Great value
Was a bit nervous about the blocked drain to be honest. Exactly what I asked for, nothing more nothing less. No pressure, no upselling, just good honest service. Been telling everyone about them. Would use again.

Thank you for the kind words Jenny. Recommendations like this mean a lot to a small plumbing company.

Thank you
Quoted £290 and that is exactly what I paid. Price was £290 which was less than I had been quoted elsewhere. Told everyone at work about them.
