“Just an email to say thankyou you to you and your team in setting up the cleaning contract for LMG’s new office.

From notifying you of our decision to Serna starting on site, it was a very quick turnaround and we appreciate the efforts in making that happen.”

Head of Procurement 

“As stated previously your team was very professional during the coronavirus pandemic providing vital cleaning services for the project. The operatives provided were very diligent and adhered to all government guidelines. This in turn helped set precedent to all other contractors working on the project.

Resourcing of labour and cleaning products was well organised especially with the impact of COVID. If we had a resource issue it was quickly resolved.

Thanks again to you and your team.”

Wates Construction, London & Kent

“I have dealt with Serna Cleaning for the last six months and have been extremely pleased with the company’s standards.

The cleaners come 5 times a week and do a consistent cleaning job throughout our office and showroom and ensure that they complete all areas covered in our agreement. When I have had an occasion to see the cleaning team, they have been friendly and acted in a professional manner.

The excellent team of cleaners and back up staff are always willing to tackle other tasks and have helped me in difficult situations on numerous of occasions. Furthermore, the management team always promptly addresses and issues and it is with great pleasure that I give Serna Cleaning the highest of recommendations.”

Site Manager, Norr 11

“I moved my cleaning contract to Serna Services in September 2012 after continually poor service from a franchised cleaning company. The difference between the two was immediately clear.

The high level of cleaning and service is the same today as it was on day one. So often with cleaning companies you receive excellent initial levels of service that quickly drop off, this is not the case with Serna Services. Communication is excellent and frequent. If ever I need anything extra completed it is done so immediately without fuss. On the one occasion something was missed (and it was extremely minor!) it was followed up straight away and rectified.

As a customer you immediately get the sense that Serna Services is clearly a family run business that is big on scaled and far more professional than their rivals. The combination of these two elements proves to be very reassuring.”

General Manager, Phoenix Cinema

“We have been using Serna Services since April 2013 and we are extremely pleased with the service they provide.

Their employees are efficient, friendly, and quick workers. In an industry where cleanliness is key, we are very happy with the level of service we receive.

After years of using erratic companies, we can attest to the consistent service provided by Serna and we now exclusively use their company.”

Operations Manger, Queen Anne Street Medical Centre

“We write to recommend Serna as a competent and effective cleaning sub-contractor to the cleaning industry.

Serna provided ample resources to achieve a challenging program of work after our final QA inspections always completed the cleaning to our satisfaction.

When we called upon Serna for an additional final clean (following defect rectification works by other sub-contractors), Serna where quick to respond with a team of 30+ cleaners and the requisite plant under the keen and dedication supervision.

I feel certain you will be satisfied with Serna’s cleaning Service, as we have been.”

Senior Project Manager, Vinci Construction UK Limited

“We are currently in our second year with Serna Cleaning. I must say ‘I wished we had found them sooner’ as they have been a ‘breath of fresh air’, compared to our previous cleaning company.

We have established a good relationship with them and find they address our needs and are very flexible with adjusting their schedule to match ours.

Their operatives are supervised/managed by Neil, whose humble, gentle, courteous nature is matched by his appearance, grooming and smell.”

Site Manager, Earlham Primary School

“We confirm that we have dealt with Serna Services since 2004, during which time they have provided us with excellent service in the areas of beginning and end of tenancy professional clean as well as housekeeping.

We consider them very professional and reliable and due to the excellent result of their work we have been able to recommend them to clients and tenants for regular domestic cleaning and key holding management.

We have no hesitation in recommending them for the above services”

L Condoleta, Managing Director

“From the first meeting with Mauricio I was impressed with the level of care and the personal approach to customer relations. The costs were very competitive; however, the level of detail taken throughout our office clean was what impressed us most.

The cleaning has been structured so as to provide no disruption to our office working hours and we have noticed a marked improvement as to the level of work compared with our previous office.

Another benefit of moving to Serna Services is the way Mauricio has taken the hassle and time consuming ordering consumables away from more. Whenever any products need replenished, or suggestions or improvements, Mauricio will let me know and proceed once authorised. This proactive approach is a real advantage.

I wouldn’t hesitate in recommending Serna Services and am delighted we made the choice to become their client.”

Finance Director, More Creative Ltd

“We have been using Serna Services for cleaning our school since August 2011 and have been very impressed with the professional way they work. Our school is now much cleaner than it was with our previous provider.

Serna have established very good protocols and encouraged the staff they took on through TUPE to raise their game. There are very few problems but if there is an issue they get onto it straight away. I can thoroughly recommend them.”
