Kitchen extract cleaning in Portsmouth

TR19® kitchen extract cleaning in Portsmouth

Portsmouth is a naval city, built largely on Portsea Island, with Southsea’s seafront, Gunwharf Quays, a university and a large hospital all within reach. Restaurants, pubs, hotels and canteens across the city depend on extract systems that need regular cleaning. We clean kitchen extract to BESA’s TR19® Grease specification across Portsmouth, from Old Portsmouth and Southsea to Cosham and beyond.

We survey first, from photos or on site, and give you a fixed quote, usually within one working day. Cleaning happens when the kitchen is closed: evenings, overnight or at weekends. Afterwards you get a TR19® certificate and a photo report with before and after pictures. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. See kitchen extract cleaning for what a full clean covers.

If you’re not sure when your extract was last cleaned, a TR19 inspection with grease readings shows where you stand. It is a sensible first step after taking over a lease or before an insurance renewal.

Naval heritage, the seafront and a busy island city

Portsmouth packs a lot onto a small island. The Portsmouth Historic Dockyard and the waterfront at Gunwharf Quays draw visitors all year, and Southsea’s seafront has restaurants, cafés and pubs that are busiest in summer and at weekends. Many of these kitchens cook for long hours in peak season, which can move them into a heavier BESA cleaning band for part of the year. Grease thickness testing shows whether the interval needs to be shorter.

The coast brings salt air, which can corrode roof fans, housings and fixings. When we clean the extract fan, we check its condition and can repair or replace it.

Much of the city is dense terraced streets, with restaurants and takeaways in converted shops and flats above. In those buildings the extract often runs up the back of the property past windows, and a clean duct protects the people living above as well as the business. The University of Portsmouth, Queen Alexandra Hospital, schools and care homes add institutional kitchens that cook to fixed timetables, which makes planning cleans around holidays and meal times straightforward.

Takeaways are a big part of the city’s food scene, and many open from lunch until late, seven days a week. Fryers, grills and woks working that hard can push a short duct into the heavy band, so grease readings and a regular grease filter exchange help keep it under control.

Food Standards Agency records list about 262 restaurants, cafés and canteens, 152 takeaways, 95 pubs and bars and 16 hotels and guest houses within roughly a mile and a half of the centre of Portsmouth, plus 48 schools and colleges and 49 hospitals, care and childcare premises. Every one that cooks under a canopy has an extract that needs cleaning. Source: FSA food hygiene rating data, October 2026.
