About our grease filter exchange in Haslar
A filter service works alongside TR19® cleaning, not instead of it. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. So the canopy, plenum and ducts still need their full TR19 clean. The work covers baffle filters, restaurants and pubs and island canopies, and common reasons people get in touch are filters that come out of the sink still dirty and missing filters in the filter bank.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Kitchen extracts in Haslar
Sea air reaches Haslar, which sits within about 1 mile of the coast. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. The FSA’s data shows about 40 bars, pubs and nightclubs and about 4 hotels, B&Bs and guest houses registered in Haslar and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Hampshire and Isle of Wight Fire and Rescue Service covers Haslar. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Term dates shape school work: for a school like Haselworth Primary School, an extract clean fits neatly into a half-term or summer break. Church and community hall kitchens, near St Francis or anywhere around Haslar, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens, like those at hospitals such as Gosport War Memorial Hospital (about 1.2 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Managing agents and facilities teams in Haslar
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
What affects the cost of grease filter exchange
Your quote is based on your site. We consider:
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- Parking and loading at the site
- Site requirements such as sign-in and permits
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.
What to send for a quote
What to send for a quote:
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, call us on 0345 646 2711 or send us an email.
In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Questions from Haslar
Can sea air affect grease filter exchange in Haslar?
It can. Salt air reaches Haslar, which is within about 1 mile of the coast, and it speeds up rust. Corroded fixings and housings are noted on the report so they can be dealt with.
Can you get to a site in Haslar?
Yes. Haslar is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Which grease filters does the service cover?
Both baffle filters and mesh filters are covered. At the start, we note what your canopies use so every set we bring fits.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What should go in our maintenance log?
Everything that shows the system is looked after: our reports and pictures, any certificates and your in-house logs. A single log for each site works best.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
What grease filter exchange can’t fix
Grease filter exchange can’t fix everything, and we’d rather say so up front. It does not solve:
- Odours from the discharge that filters will not stop
- Grease already built up in the ductwork, which needs a full TR19 clean
- A noisy or failed extract fan
If you are not sure, just phone us on 0345 646 2711 or email us and we will give you a straight answer.
Where we work
- Mesh filters
- Island canopies
- School and hospital kitchens
- Baffle filters
- Wall canopies
- Restaurants and pubs
What the work involves, part by part
Mesh filters
Grease lodges deep in the layers of a mesh filter, so a quick rinse rarely gets it clean.
School, care home and staff kitchens
Lighter kitchens can often go longer between changes. The interval is set to fit.
What happens on the day
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the grease filter exchange, tidy up and hand over the paperwork. On site, the work takes well under an hour for most canopies. A few pictures of the system help us make the most of a visit to a place like Haslar.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.
Related advice
Why deal with it now?
Once filters are saturated, more grease gets past them. That makes the next full clean a bigger job, and grease may build up faster than the cleaning interval allows. Our emergency line runs 24/7, but a planned visit to Haslar is calmer for everyone.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
