Welcome to Harp Windows

Looking after our customers since 1989



Based in Hertfordshire, Harp Windows is a family owned and family

run company, and was established back in 1989. We both manufacture

and install high quality replacement windows, doors and conservatories.

Over the years, we've worked hard to build up an established local

reputation based on professional integrity, efficient customer service,

quality and value for money.


Customer Comments


"Extremely professional, courteous and


friendly service from first visit to final



Mr & Mrs Pearce - Watford


"We would like to commend you on an

excellent service throughout. Andy and

Martin fitted the windows very

professionally, and they are an excellent

team. Very clean, tidy and friendly. We will

have no hesitation in recommending you to

all. Many of our neighbours have already

commented that the windows look fantastic.

We are extremely pleased with the result.

Thank you once again for the wonderful

service throughout."

Mr & Mrs Sheppard - High Wycombe


"This has been an exceptional professional

service from all the people I've dealt with"

  Charity sponsorships                  

To celebrate our 20th anniversary in 2009, we ran a charity sponsorship throughout the year. We made

a charitable donation for every installation undertaken, and our customers could choose which charity

we donated to for their installation. Due to the success of this initiative, we have decided to continue

and to date we have donated well in excess of £4000:

  • 2009 Help for Heroes = £380, Cancer Research = £870, Harefield Trust = £190

  • 2010: Help for Heroes = £710, Cancer Research = £1130, Harefield Trust = £100

  • 2011 Help for Heroes = £550, Cancer Research = £680, Harefield Trust = £220

Customer feedback

We are delighted that feedback from the Consumer Protection surveys is as good as ever. Our results for the year 2012 are as follows:



Customer satisfaction is of utmost importance to us, and we cannot emphasize enough the value of good

customer communication, particularly during an installation. To this end, in June 2008 we introduced a

straightforward customer satisfaction survey, which is given to all our customers to complete after

installation. Customers are not obliged to complete these questionnaires, however we are delighted to

have received an excellent response from them.
