BEFORE YOU BOOK

Check before you book

No register applies

No licence or register applies to sash window restorers in England, Wales, Scotland or Northern Ireland, so anyone may offer sash window restoration. The law steps in only where sash window restoration turns into gas work, notifiable electrical work or building work.

Ask for a business name, the insurer and a written description of the sash window restoration.

Listed buildings

Section 7 of the 1990 listed buildings legislation for England and Wales says that works altering a listed building in a way that affects its character need listed building consent, and section 9 makes doing them without it an offence. If your home is listed, ask the council before the sash window restoration.

For a listed home, ask the council whether the sash window restoration needs listed building consent before booking. legislation.gov.uk →

Lead in old paint

HSE says lead was widely used in paint until the 1960s and not out of all paint until the early 1980s, and advises against dry sanding or burning it off; wet abrasives, chemical strippers or extraction are the safer methods.

Ladders and work at height

The Work at Height Regulations 2005 (and Northern Ireland's own of the same year) require work at height to be planned and done with suitable equipment; HSE's ladder guidance is a 1-in-4 angle and three points of contact. Stairwells and high ceilings make the sash window restoration a work-at-height job.

For high or stairwell work, ask what access equipment the sash window restoration will use. hse.gov.uk →

VAT

Sash window restoration is standard-rated at 20%, draught-proofing, glazing and painting included. Over the £90,000 registration threshold a trader must charge it and show it separately; under it there is no VAT and no VAT number.

Ask the sash restorer for the VAT number and whether the price per window is plus VAT. gov.uk →

“Is my house listed, and does this sash window work need consent?”

A good answer: They tell you to check with the council and avoid changing materials until you know.

“How will you prepare old paint on the sashes?”

A good answer: Without dry sanding or burning, because of lead.

“Will you splice rotten timber or replace the sash?”

A good answer: Splice where possible, replace only what cannot be saved.

“Which draught-proofing will you fit to the sash windows?”

A good answer: Brush seals and new beads, named.

“Can you keep the old glass?”

A good answer: Yes where it survives; heritage glass to match if not.

“What is the price per sash window?”

A good answer: Each window priced with its work listed.

STEP 1Put it in writing to the sash window restorerStart with an email to the sash window restorer: the problem, photos and what would put it right. A trader's sash window restoration is covered by section 49 of the Consumer Rights Act 2015, and the remedies — doing it again, or a price reduction — follow from sections 55 and 56.
STEP 2Use the make-it-right stepRate the sash window restoration below four stars and you are asked whether the sash window restorer should see the complaint first; we keep it moving until it is answered, then you review.
STEP 3Listed buildings and Trading StandardsUnauthorised works to a listed building are for the council's planning team. For a dispute, Citizens Advice (0808 223 1133), Advice Direct Scotland (0808 800 9060) or Consumerline (0300 123 6262).
STEP 4Small claims, if money is owedA claim against the sash window restorer that will not settle can go to court without a lawyer — the small claims track for up to £10,000 in England and Wales, simple procedure for up to £5,000 in Scotland, and the small claims court for up to £5,000 in Northern Ireland.

Hiring a sash window restorer: questions people ask

No. No register applies; listed building consent can be needed in a listed home.

Like-for-like repair may not; anything that affects the building's character does. Ask the council.

It may contain lead; HSE advises against dry sanding or burning it off.

£120–£1,200 per window, with about £400 typical for a repair and overhaul. What pushes it up or down is in the sash window restoration price guide; search above by town for restorers in your area.

Usually, as a reversible repair, but on a listed building ask the council first; brush seals and new beads are the common method.

Half a day for new cords; one to two days per window for a full restoration.
