Family run · Southampton & Eastleigh · 25 years
Your local plumbing, heating and electrical experts
Welcome to BBI Heating & Electrical. We are based in Eastleigh and Southampton, proudly serving Hampshire. Our team specialises in all aspects of plumbing, heating and electrical installations and services — from traditional solutions like boilers and electrical wiring to renewable installations.
Our commitment to delivering you the best service is backed by our 25 years experience and "gold standard" MCS accreditation. You can trust us to deliver quality workmanship and reliability for all heating and electrical needs.

What makes us different
Most of this market is split down the middle. We are not.
There are two kinds of company competing for your renewable installation. Renewable specialists, who understand heat pumps but subcontract the electrics and cannot service your boiler. And national volume installers, who sell a product configured online and send a contractor you have never met. We are a third thing: one local firm holding every accreditation the job needs.
Six accreditations, one contractor
Gas Safe for gas. NICEIC for electrical. MCS (NIC601962) for renewables and grant access. F-Gas for refrigerant. WaterSafe for water, vetted by Southern Water. OFTEC for oil. Very few firms our size hold all of them.
Family run, and it shows in the work
Twenty-five years of Hampshire history means we are still here when something needs adjusting in year three. Our projects include barn conversions, low-profile underfloor heating retrofits and a seven-bedroom guest house heat pump cascade — all in this county.
We publish our prices
Service prices are on the website, and two of them can be booked online. That is a deliberate choice: you should be able to see a number before you speak to anyone.
Verifiable
Our accreditations, in full
Each of these is checkable on a public register. We list our registration numbers because you should be able to confirm them without asking us.
Manufacturer and scheme approvals
