By Kevin Potter · 5 March 2026. Your primary category is roughly 32% of where you rank in the Local Pack. Most tradespeople pick the wrong one. Here is the correct one for every UK trade plus the nine secondary slots Google gives you free.
Of every field in Google Business Profile, the primary category does the most work for the least effort. It is one click, it takes thirty seconds, and it is often the single largest ranking signal Google receives about your business.
It is also the field most tradespeople get wrong. We have audited over a hundred trade profiles. Around 60% have the suboptimal primary category. The most common error: builders ticking "Builder" when "General Contractor" is the higher-volume choice.
Below is the correct primary for every common UK trade. After the lookup table, the secondary categories that compound the signal.
| Your trade | Correct primary GBP category |
|---|---|
| Plumber | Plumber |
| Electrician | Electrician |
| Builder | General Contractor |
| Painter & Decorator | Painter |
| Removal company | Moving and Storage Service |
| Roofer | Roofing Contractor |
| Gas engineer | Heating Contractor |
| Locksmith | Locksmith |
| Landscaper | Landscaper |
| Carpenter / Joiner | Carpenter |
| Plasterer | Plasterer |
| Cleaner (residential) | House Cleaning Service |
| Architect | Architect |
| Garden / Tree surgeon | Tree Service |
Google lets you add up to 9 additional categories beyond your primary. Each one is a separate signal telling Google about another service you offer. They are free. Most tradespeople ignore them.
Here is how to fill all 9 by trade:
Plumber. Drainage Service, Boiler Supplier, Bathroom Remodeler, Central Heating Service, Gas Engineer, Pipework Contractor, Emergency Plumber, Water Damage Restoration Service, Septic System Service.
Electrician. Electrical Installation Service, Lighting Contractor, Solar Energy Equipment Supplier, EV Charging Station, Fire Alarm Supplier, Security System Installer, Electrical Repair Shop, CCTV Installation Service, PAT Testing Service.

Roofer. Roofing Supply Store, Gutter Cleaning Service, Chimney Sweep, Insulation Contractor, Skylight Contractor, Solar Energy Equipment Supplier, Construction Company, Flat Roofing Contractor, Lead Worker.
If your trade is not listed, pick categories that match each main service you offer. Avoid adding categories you do not actually deliver, since Google can suppress profiles that look stuffed.
Picking your primary category by what sounds prestigious. "Construction Company" sounds bigger than "General Contractor", but for a builder it gets fewer local searches. Pick for search volume in your area, not for ego.
Changing the primary category frequently. Each change is a reset. Pick once, leave it alone for at least six months.
