Managing agents and facilities teams in Digswell

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.

Grease trap cleaning in Digswell, done properly

Fats, oils and grease are the main cause of blocked kitchen drains. Down the line, they can add to fatbergs in the sewer. A well-maintained trap holds them back. The work covers restaurants and takeaways, inline grease traps and kitchen waste pipes, and people most often call us about a kitchen drain that smells and a grease trap that hasn’t been emptied in a long time.

Work in a smaller place like Digswell is planned around your opening hours, and the journey is planned ahead.

The paperwork matters as much as the work. Each visit is written up with pictures, 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.

Grease trap cleaning around Digswell

There are about 55 restaurants, cafés and canteens and about 13 takeaways and sandwich shops across Digswell and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Fat from washing up sets hard in pipes, and kitchens like these produce plenty of it. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in Digswell. Walls, floors, ceilings and equipment are all part of what they look at. Photos and dates from each deep clean make a useful record.

If you run catering at a healthcare site, such as a hospital like Queen Elizabeth II Hospital about 2.5 miles south, deep cleans and grease trap visits are planned so meals still go out. For busy kitchens close to Welwyn North station, deep cleans and grease trap work can be done after closing.

Honest limits

We’ll always give you a straight diagnosis, so here’s what this work can’t put right:

  • Leaking pipework or sink wastes, which need a plumber
  • Sewer problems outside the premises
  • A grease trap that is too small for the kitchen

If in doubt, ring 0345 646 2711 or use the quote form and we’ll say what we think before booking.

What we work on in Digswell

  • Inline grease traps
  • Pot wash sinks
  • Restaurants and takeaways
  • School and care home kitchens
  • Under-sink grease traps
  • Kitchen waste pipes

How the visit works

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes less than an hour for many under-sink units. For a place like Digswell, we load the van from the survey notes so the work can be done in one visit where possible.

  1. We agree a time when the sinks are not needed.
  2. The trap is opened up and checked.
  3. We remove the grease layer and settled solids.
  4. We clean the baffles, inlet and outlet.
  5. The trap is closed, tested and the next clean discussed.

How to prepare

  • Mention any locked doors, roof access or ceiling voids
  • Let us know when the site is closed or quiet
  • Make sure someone can let us in and lock up afterwards

Fixed quotes for grease trap cleaning in Digswell

You’ll get a fixed price before any work starts. It takes into account:

  • Whether it’s a one-off visit or part of a schedule
  • The size of the system
  • Working hours and out-of-hours timing
  • Where the site is and how we reach it

Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

Asking for a quote

Photos let us diagnose from a distance. The most useful are:

  • The postcode and the type of business
  • Your opening hours and when the area is out of use
  • Photos showing the whole system and its surroundings
  • Detail shots of panels, filters and grilles

Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.

What staff can safely do

Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

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 don’t reach the grease that builds up further in. That part needs specialist access and equipment.

What the work involves, part by part

Grease interceptors

An interceptor works on the same principle as a smaller trap. Cooling water lets grease rise and solids settle.

Under-sink grease traps

An under-sink trap is out of sight. When they fill, the sink slows and starts to smell.

Digswell questions

Which environmental health team covers Digswell?

That’s Welwyn Hatfield council, whose environmental health officers carry out food hygiene inspections in Digswell. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.

Do you work overnight in Digswell?

Yes, out-of-hours work is a big part of what we do. That way a site in Digswell doesn’t have to lose a day’s trading. Just call 0345 646 2711, or email photos with your opening times and we will plan around them.

Will I get paperwork for my records?

Yes. Each visit ends with a written report and pictures, covering the work, any areas we couldn’t access and the recommended next date. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.

What is TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.

Which records should we keep?

Everything that shows the system is looked after: our reports and photos, any certificates and your in-house logs. A single log for each site works best.

How often should a grease trap be cleaned?

It varies. We look at how full the trap is and how quickly it fills, then suggest a schedule.

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.

What types of premises do you cover?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

Common problems we fix in Digswell

Waste cooking oil poured down the sink fills a grease trap far faster than washing-up. Small amounts soon build up.

Common reasons sites call us include:

  • Gurgling drains in the kitchen
  • Sinks that drain slowly
  • A bad smell from the sinks or drains
  • An overdue grease trap

Half-term is a good time for school kitchens, at schools like Harwood Hill Junior Mixed Infant and Nursery School for instance, to have the grease trap emptied and the kitchen deep cleaned.

Before you book anyone

  • What paperwork you get at the end
  • Whether the price is fixed
  • If they look at the system before pricing
  • When they can work, and whether that’s outside your opening hours
