What affects the quote in Blackheath
We do not publish a price list, because sites vary so much. The quote depends on:
- The size of the system
- Site rules, permits and inductions
- When the work can happen, such as evenings, overnight or weekends
- How many systems or sites are involved
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
Asking for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- The times we could work without disrupting the site
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.
Grease trap cleaning for kitchens and businesses in Blackheath
Every trap is different. Under-sink units are small and fill quickly, while inline traps and interceptors hold more. We assess the trap and how fast it fills and suggest an interval that suits. We are often asked to deal with drains that gurgle and bubble and a full, neglected grease trap, on pot wash sinks, restaurants and takeaways and under-sink grease traps.
In rural areas, a kitchen may drain to a private system rather than a public sewer, so keeping fat out with a working grease trap matters even more.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

When to call us in Blackheath
Every pan and plate washed sends grease towards the drain. They cool and float to the top of the trap and the grease layer grows.
Common reasons sites call us are:
- An inline trap or interceptor due for cleaning
- A grease trap that hasn’t been emptied in a long time
- A blocked kitchen drain caused by grease
- Scheduled grease trap emptying
Where a church or community hall near Church of St Martin, or anywhere in Blackheath, has a kitchen used by volunteers, a periodic deep clean keeps it ready for the next event.
Questions to ask before booking
- What happens if part of the system can’t be accessed
- If the quote is a fixed price or an estimate
- How VAT is shown on the quote
- Exactly which parts of the system are covered
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, which takes an hour or two in most kitchens, depending on the size and condition of the trap. Somewhere like Blackheath, lanes, gates and parking are worth mentioning in advance.
- We agree a time when the sinks aren’t needed.
- We open the trap and look at its condition.
- We remove the grease layer and settled solids.
- We clean the baffles, inlet and outlet.
- The trap is closed, tested and the next clean discussed.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
Ask for a quote
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What happens if it’s left?
A blocked drain can stop a kitchen in its tracks. Water won’t drain away and waste water can come back up. Cleaning the grease trap on time helps prevent it. If the system at a site near Blackheath fails, there may be nowhere nearby to move to.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.

Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Use strainers in the sink plugholes
- Report slow or smelly sinks early
- Tell us if your menu or hours change
- Do not store things on top of the trap
If we spot problems beyond the trap, such as a drain that still runs slowly, we will tell you. It may need a drainage specialist to investigate.
If the kitchen has got busier, the trap fills faster. Booking cleans more often keeps the drains flowing.

Blackheath: your questions answered
Which council inspects kitchens in Blackheath?
In Blackheath, it’s Waverley council that carries out food hygiene inspections. Keep the dates of your last deep clean and grease trap visit with your food safety records, ready if an officer asks.
Can a school kitchen in Blackheath be done out of term time?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of Blackheath. Just call us on 0345 646 2711, or send details by email with your term dates and we will plan around them.
How much time does a grease trap clean need?
The size and state of the trap make the difference, but a clean generally takes a short visit for a small trap and longer for an inline unit or interceptor. We’ll confirm when we quote.
Do you work in Blackheath?
Yes. Our area takes in London and the counties of South East England, and that includes Blackheath.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
