How the job changes from site to site
Grease interceptors
An interceptor works on the same principle as a smaller trap. Grease floats and solids sink.
School, care home and staff kitchens
Drains in care settings need to keep flowing. Visits are planned between meals.
Grease trap cleaning in Forest Hill, done properly
Kitchens in Forest Hill use us for grease trap cleaning, whether it’s an under-sink unit or a larger inline trap. Visits are booked around your service, so the kitchen keeps running. Common call-outs are for washing-up water that won’t drain away and a bad smell from the sinks or drains, across school and care home kitchens, restaurants and takeaways and under-sink grease traps.
Across London, council environmental health teams inspect food businesses, and the cleanliness of the whole kitchen is part of what they look at. Kitchens in Forest Hill often book a deep clean before or after an inspection.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes anything from under an hour to a few hours, depending on the trap. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Forest Hill.
- We agree a time when the sinks are not needed.
- The trap is opened up and checked.
- Built-up grease and food waste are taken out.
- We clean the baffles, inlet and outlet.
- We close it up, check it drains and suggest when it needs cleaning again.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
- Make sure someone can let us in and lock up afterwards

What a clean won’t put right
We will always give you a straight diagnosis, so here’s what grease trap cleaning will not do:
- Blockages further down the drainage network
- Broken pipework below ground
- A trap undersized for the amount of cooking

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Common questions in Forest Hill
Do you work overnight in Forest Hill?
Yes. We work evenings, overnight and at weekends. It means the site in Forest Hill keeps running as normal. Your opening times are the first thing we ask for.
Which environmental health team covers Forest Hill?
Food hygiene inspections in Forest Hill are carried out by Southwark council. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.
Where does the grease from the trap go?
We take it away. There’s nothing left for your team to deal with after we’ve finished.
What if parts of the system can’t be reached?
We record them on the report, with photos where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
Which records should we keep?
Each report and certificate we give you, kept together in your maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How do you protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Commercial kitchens in Forest Hill
Look up Forest Hill on the FSA’s food hygiene register and you will find about 210 restaurants, cafés and canteens and about 147 takeaways across Forest Hill and its immediate surroundings (about a mile and a half). Each of them sends fat, oil and grease towards the drain, which is why grease traps need regular emptying. Food hygiene inspections in Forest Hill are the job of Southwark council’s environmental health team. An inspection covers the structure of the kitchen as well as the food. Having the dates of the last deep clean to hand saves digging for them on the day. Compact London kitchens collect grease in tight corners, which an overnight deep clean can reach.
A summer deep clean suits schools such as Fairlawn Primary School, as the kitchen can be stripped back with no lunches to serve. If you look after a hall kitchen near Honor Oak Christian Fellowship Centre or anywhere in Forest Hill, a deep clean between busy seasons is easier than a scramble before a big event. Healthcare kitchens cook through the year, so a deep clean has to be fitted around meals; Dulwich Community Hospital, about 1.5 miles north-west, is the nearest hospital to Forest Hill.
Forest Hill is about 2 miles south-east of East Dulwich, in Greater London. Whether your site is in the middle of Forest Hill or further out, grease trap cleaning is available to all kinds of commercial premises, from small sites to large estates. Across Greater London, we cover 764 places, and Forest Hill is one of them.
Every address in SE23, SE22 and SE26 is covered for grease trap cleaning, from busy streets to back roads. Whether your site is on Ewart Road, London Road and Rojack Road or a nearby road, our technicians can take on the work. Close by, we work in Honor Oak (1 mile north), Perry Vale (1 mile south-east), Brockley (1 mile north-east), Crofton Park (1 mile north-east) and Dulwich (1 mile west). Larger places within reach include London (4 miles north-west), City of Westminster (6 miles north-west), Marylebone (6 miles north-west), Kensington (7 miles north-west), St Pancras (6 miles north-west) and Shoreditch (6 miles north).

Other landmarks nearby include Greenwich Castle (3.1 miles north-east) and Horniman Museum and Gardens (0.5 miles south-west). Not far away are One Tree Hill and Knight's Hill.
Managing agents and facilities teams in Forest Hill
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Leave it or put it right?
Pests are drawn to grease and food waste. A clean trap is less of an attraction, alongside good kitchen hygiene. A booked night’s work in Forest Hill costs you no trading time; an unplanned closure does.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
Why us?
- A written report with photos after every visit
- A fixed price before any work starts

How we price grease trap cleaning
The price is fixed before any work begins. It’s based on:
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- How big the system is
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Asking for a quote
To help us quote quickly, please include:
- Wide pictures of the system and the area around it
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
For a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We usually come back within one working day.
