The COMBI-NATION pricing policy is very competitive and our aim is to keep it that way.

Central heating and plumbing work
Customer Service
Combi nation came and quoted for replacing our old boiler with a new combi. They were honest about extra costs for pipe work, but didn't try and charge for this unless we needed it. The work was done quickly and neatly and we were really happy with our boiler. We then decided to decorate and needed a hand with a radiator, again done quickly and without any mess. Carrying on with more work they removed a sink from a bedroom. Overall really happy with all the work that has been done and I wouldn't hesitate to recommend to others and to get them back for any other plumbing work we need.

Highly Recommended Plumbers
Customer Service
Combi-nation had the not so envious task to replace the old boiler in my new property. I had 4 engineers quoting me for the work and Combi-nation were by far the best value for money. Though their quote was lower than the other companies, you wouldn't be able to tell from the first class work the guys have done. Gwyn and Paul worked tirelessly for 3 days to get the new boiler fitted. During the fitting process a few issues with our central heating system were discovered. The guys let us know exactly what needed to be done and once again provided very fair prices for the work needed. And even though it was very messy work, they left our property spotless. All in all, I had a stellar experience with Combi-nation and would not hesitate to recommend them to anyone.

Excellent Service!
Customer Service
I have been using this company for a while now and cannot fault them in any way. I have always had great service from everyone that works here. As a landlord we need a company that can go out to properties on short notice and cost reasonable prices which Combi-Nation have done every time!. I would recommend them to anyone.
