Fixed quotes for TR19 inspection in Tower Hill
We do not publish a price list, because no two systems are the same. The quote depends on:
- What state the system is in
- Working hours and out-of-hours timing
- How many systems or sites are involved
- Site rules, permits and inductions
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.
Asking for a quote
Before you ask for a quote, gather:
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
To get a fixed quote, give us a ring on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
About our TR19 inspection in Tower Hill
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you’re on. Common call-outs are for kitchens whose menu or hours have changed and systems that need surveying before cleaning, across access surveys, deposit thickness tests and post-clean checks.
Somewhere as small as Tower Hill, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- File every inspection report with your certificates
- Report grease dripping from the canopy
- Keep to the recommended interval
- Tell us if menus or opening hours change
For an insurer audit, send them the report as it is, including readings, pictures and any inaccessible sections.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Different parts, different methods
Extract fan and discharge
Grease on the fan adds to wear. Readings show if it needs attention before the next clean.
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, and readings show whether that is enough.
Common questions in Tower Hill
Do you cover smaller places like Tower Hill?
Yes. Tower Hill is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Can the work in Tower Hill be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Tower Hill needn’t be disturbed. Your opening times are the first thing we ask for.
What does a pre-clean survey involve?
It’s a look at the whole extract before it’s cleaned, with readings and pictures. We can work from photos and details, or visit, whichever suits the system.
What do the grease readings need to be?
Two figures matter: a mean of no more than 200 microns between cleans, and 500 microns at any single point, which needs immediate spot cleaning. Our report sets your readings against both.
Do you survey before quoting?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
How it works
Each visit runs to the same pattern: protect the area, make the system safe, carry out the TR19 inspection, clear away and leave you the report. The visit itself takes an hour or two for a single kitchen, longer for a large or complex system. A quick note on how to find the site and where to park makes a visit to Tower Hill run smoothly.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Each test point and any access problems are photographed.
- You get a report with readings, pictures and recommendations.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Agree a time when the area can be out of use
Get a fixed quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
Advice
Tower Hill kitchens: local notes
The Food Standards Agency lists about 17 bars, pubs and nightclubs and about 6 hotels and B&Bs as registered food businesses across Tower Hill and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Tower Hill get their food hygiene inspections from Horsham council. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Tower Hill is West Sussex Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
For kitchens close to Christs Hospital station, where the day often starts early and ends late, the extract can be cleaned overnight. If you run catering at a healthcare site, such as a hospital like Horsham Hospital about 1.3 miles north-east, the extract may need cleaning more often than a part-time kitchen. Volunteers running a hall kitchen near Parish Church of St Mary, or anywhere in Tower Hill, may not know when the extract was last cleaned, and a grease test settles it.

Why it’s worth doing now in Tower Hill
Without readings, you’re guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, which you will not know without measuring. If the system at a site near Tower Hill fails, there may be nowhere nearby to move to.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
